Federal Plan Requirements for Greenhouse Gas Emissions From 
Electric Utility Generating Units Constructed on or Before January 8, 
2014; Model Trading Rules; Amendments to Framework Regulations

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: In this action, the Environmental Protection Agency (EPA) is 
proposing a federal plan to implement the greenhouse gas (GHG) emission 
guidelines (EGs) for existing fossil fuel-fired electric generating 
units (EGUs) under the Clean Air Act (CAA). The EGs were proposed in 
June 2014 and finalized on August 3, 2015 as the Carbon Pollution 
Emission Guidelines for Existing Stationary Sources: Electric Utility 
Generating Units (also known as the Clean Power Plan or EGs). This 
proposal presents two approaches to a federal plan for states and other 
jurisdictions that do not submit an approvable plan to the EPA: a rate-
based emission trading program and a mass-based emission trading 
program. These proposals also constitute proposed model trading rules 
that states can adopt or tailor for implementation of the final EGs. 
The federal plan is an important measure to ensure that congressionally 
mandated emission standards under the authority of the CAA are 
implemented. The proposed federal plan is related to but separate from 
the final EGs. The final EGs establish the best system of emission 
reduction (BSER) for applicable fossil fuel-fired EGUs in the form of a 
carbon dioxide (CO2) emission performance rate for steam-
fired EGUs and a CO2 emission performance rate for natural 
gas-fired combined cycle (NGCC) units, and provide guidance and 
criteria for the development of approvable state plans. The purpose of 
the proposed federal plan is to establish requirements directly 
applicable to a state's affected EGUs that meet these emission 
performance levels, or the equivalent statewide goal, in order to 
achieve reductions in CO2 emissions in the case where a 
state or other jurisdiction does not submit an approvable plan. The 
stringency of the emission performance levels established in the final 
EGs will be the same whether implemented through a state plan or a 
federal plan. The EPA is also proposing enhancements to the CAA section 
111(d) framework regulations related to the process and timing for 
state plan submissions and EPA actions. The EPA intends to finalize 
both the rate-based and mass-based model trading rules in summer 2016.

DATES: Comments. Comments must be received on or before January 21, 
2016.

I. General Information

A. Executive Summary

    In the CAA, Congress created a partnership between the EPA and the 
states. Under section 111(d) of the CAA, the EPA establishes emission 
performance levels based on its determination of the BSER for existing 
sources of air pollution and provides guidelines for state plans to 
apply standards of performance to their sources that meet the BSER 
level of performance. The EPA promulgated EGs under CAA section 111(d) 
which set source-level CO2 emission performance rates for 
the EGUs at certain large fossil fuel-fired power plants (``affected 
EGUs''). States then apply these EGs to their sources in developing 
state plans to achieve these emission performance levels for EPA 
approval, or initial submittals, by September 6, 2016. The amount of 
reductions in CO2 that the EPA determined to be achievable 
for these sources is based on its determination of what constitutes the 
BSER. This determination is finalized in the EGs, which are designed to 
maximize the flexibility of both states and affected EGUs in meeting 
CO2 emissions performance rates. While states may impose the 
emission rates directly on their affected EGUs, states also have the 
option of submitting more tailored plans that meet state-specific 
emissions goals. The EGs also provide flexibility by allowing for 
emissions trading and multi-state compliance options.
    While it has been the EPA's longstanding view that the statute 
identifies states as the preferred implementers of CAA programs, the 
agency makes clear in the EGs that states cannot and will not be 
penalized for failing to participate in this program. However, if a 
state does not submit an approvable plan under section 111(d) of the 
CAA, the EPA will develop, implement, and enforce a federal plan to 
reduce CO2 from the fossil fuel-fired power plants in that 
state. This is wholly consistent with the ``cooperative federalism'' 
structure of the CAA and many of our nation's other environmental laws. 
In addition, we have heard from states and other stakeholders that it 
would be helpful for the agency to present model designs for state 
plans, and a federal plan would be an appropriate means of doing that.
    Accordingly, the EPA proposes a federal plan under section 111(d) 
of the CAA for the control of CO2, a GHG pollutant, from 
certain emitting fossil fuel-fired power plants, in the event that some 
states do not adopt their own plans. Specifically, the EPA is proposing 
approaches in the form of mass- and rate-based trading options that 
provide flexibility in implementing emission standards for a state's 
affected EGUs. Both proposed approaches to the federal plan would 
require affected EGUs to meet emission standards set using the 
CO2 emission performance rates in the EGs. The federal plan 
will achieve the same levels of emissions performance as required of 
state plans under the EGs. The EPA will promulgate a final federal plan 
for only the affected EGUs in states that the EPA determines did not 
submit an approvable plan.
    At the same time, these two proposed options offer states model 
trading rules that the states can follow in developing their own plans 
in order to capitalize on the flexibility built into the final EGs. 
Thus, this document proposes four discrete actions: (1) A rate-based 
federal plan for each state with affected EGUs; (2) a mass-based 
federal plan for each state with affected EGUs; (3) a rate-based model 
trading rule for potential use by any state; and (4) a mass-based model 
trading rule for potential use by any state. The regulatory text of 
each federal plan and corresponding model trading rule is identical, 
except as indicated otherwise within the text of the model rule (for 
instance, the EPA is providing model rule text for states to use 
related to the crediting of a broader set of clean energy resources 
than is being proposed in the federal plan).
    The EPA intends to finalize both the rate-based and mass-based 
model trading rules in summer 2016. The EPA will finalize a federal 
plan for only a given state in the event that the state does not submit 
an approvable plan by the deadlines specified in the final EGs and the 
EPA takes action finding that the state has failed to submit a plan, or 
disapproving a submitted plan because it does not meet the requirements 
of the EGs.\1\ Indeed, states may simply choose to accept a federal 
plan for their sources rather than undertake the development of a plan 
of their own by not submitting a state plan. Under this proposed rule, 
a federal plan promulgated for a particular state would take the form 
of either the mass-based model trading rule or the rate-based model 
trading rule. The EPA currently intends to finalize a single approach 
(i.e., either the mass-based or rate-based approach) for every state in 
which it promulgates a federal plan, given the benefits of a broad 
trading program, as discussed in

[[Page 64969]]

section I.B of this preamble. We invite comment on which approach, 
i.e., either mass-based or rate-based trading, should be selected if we 
opt to finalize a single approach.
---------------------------------------------------------------------------

    \1\ For simplicity, at times this document may refer to the co-
proposed federal plans as ``the federal plan.'' (It may refer to the 
model trading rules in the singular as well.) Even though the 
singular is used, this term is meant to encompass both the rate-
based approach and the mass-based approach. The use of the singular 
when referring to this proposed federal plan also is intended to 
encompass all state-specific federal plans. In other words, the EPA 
intends to finalize ``the federal plan'' as a series of state-
specific ``federal plans.'' This is consistent with the agency's 
prior practice in other multi-state trading programs such as the 
NOX Budget Trading Program, the Clean Air Interstate Rule 
(CAIR), and the Cross-State Air Pollution Rule (CSAPR), where a 
single rule promulgated multiple FIPs.
---------------------------------------------------------------------------

    It is the EPA's intention to give the states as much opportunity as 
possible to set their own course for carrying out the EGs. Even where a 
federal plan is put in place for a particular state, that state will 
still be able to submit a plan, which, upon approval, will allow the 
state and its sources to exit the federal plan. In addition, as 
discussed in section VI.A of this preamble, states may take delegation 
of administrative aspects of the federal plan in order to become the 
primary implementers. And as discussed in sections V.E and VII.A of 
this preamble, states may submit partial state plans in order to take 
over the implementation of a portion of a federal plan. For instance, 
in a mass-based trading program, the agency proposes to allow states to 
submit partial state plans to replace the federal plan allowance-
distribution provisions with their own allowance-distribution 
provisions, similar to the approach we have taken in prior trading 
programs. Finally, even in states in which the affected EGUs are 
operating under a federal plan, the agency recognizes that states may 
adopt complementary measures outside of CAA programming to facilitate 
compliance and lower costs that could benefit power generators and 
consumers, directly or indirectly.
    A state program that adheres to the model trading rule provisions 
specified in this rulemaking would be presumptively approvable. States 
may submit means of meeting the EGs' requirements that differ from the 
model trading rule provisions, so long as the state demonstrates to the 
EPA's satisfaction in the state plan submittal that such alternative 
means of addressing requirements are at least as stringent as the 
presumptively approvable approach described here.\2\ Additionally, 
there are stand-alone portions of the model trading rules, such as the 
evaluation, measurement, and verification (EM&V) procedures, that would 
be approvable even if a state adopted an approach that differs from the 
federal plan. The model trading rules serve as a mechanism to 
facilitate larger trading markets since consistency with the federal 
plan allows trading across both the state and federal programs. The EPA 
expects a larger trading region is likely to result in lower overall 
costs. These and other aspects of the model trading rules and federal 
plan provide additional support for this rule as proposed. Thus, the 
proposed rule would ensure that congressionally mandated emission 
standards under authority of section 111 of the CAA are implemented, 
either by the states in the first instance, or by the EPA where needed.
---------------------------------------------------------------------------

    \2\ For example, in the context of a mass- or rate-based trading 
program, a state may submit a plan with alternative components other 
than those described, so long as the program includes each of the 
requirements and the state satisfactorily demonstrates in the state 
plan submittal that such alternative means of addressing the 
requirements are as stringent as the presumptively approvable 
approach as described, and therefore provide for the implementation 
of the state plan's emission standards.
---------------------------------------------------------------------------

    The agency is proposing a finding that it is necessary or 
appropriate to implement a CAA section 111(d) federal plan for the 
affected EGUs located in Indian country. CO2 emission 
performance rates for these facilities were finalized in the EGs. 
Tribes generally may seek ``treatment as a state'' (TAS) and submit a 
tribal plan to implement CAA programs, including programs under CAA 
section 111(d), and this proposed finding does not preclude tribes from 
doing that. However, tribes are not subject to the deadlines applicable 
to state action under the EGs and in the absence of a federal plan, 
CO2 emissions from these EGUs could go unregulated. 
Therefore, as discussed in section VI.D of this preamble, we are 
proposing a necessary or appropriate finding.
    This document also proposes certain enhancements to the process and 
timing for state submittals and EPA action in the CAA section 111(d) 
framework regulations of 40 CFR part 60, subpart B (these proposals are 
not a part of the federal plan or model trading rules). These changes, 
if finalized, would be applicable under the Clean Power Plan and other 
CAA section 111(d) rules. These changes clarify the availability of 
certain procedural mechanisms similar to those available under CAA 
section 110 (such as calls for plan revisions and the availability of 
``conditional approvals,'' etc.). They also extend the deadlines for 
EPA action, in part to conform with the timelines in the EGs. These 
changes do not alter the timelines for state action under the EGs and 
do not alter the submission requirements established in the EGs. 
Finally, the agency proposes to clarify and request comment on an 
interpretive issue raised in the Clean Power Plan proposal regarding 
whether a reconstruction or modification that is subject to a CAA 
section 111(b) standard moves an existing source out of a CAA section 
111(d) program. These proposed changes are discussed in section VII of 
this preamble. The agency intends to finalize these changes earlier 
than the finalization of the model trading rules.
    In proposing a federal plan, the EPA considered a variety of 
potential impacts that its action might have on the environment, on 
businesses, particularly in the energy sector, and on the reliability 
of the electrical grid. The agency gave extensive consideration to 
impacts on vulnerable communities, particularly low-income communities, 
communities of color, and indigenous communities. These considerations 
are discussed in sections III, VIII, IX, and X of this preamble.
    The agency convened a Small Business Advocacy Review Panel under 
the Regulatory Flexibility Act and has completed an Initial Regulatory 
Flexibility Analysis (IRFA). Various recommendations from the Panel are 
found reflected throughout this proposal. In section X of this 
preamble, the agency explains how it has conducted or intends to 
conduct all other statutory or executive order (EO) reviews that apply 
to this proposed action. The EPA also explains in this document how it 
proposes to take into consideration the ``remaining useful lives'' of 
affected EGUs in the design of the proposed federal plan, as discussed 
below in section III.G of this preamble.
    The agency considered the impacts this action could have on the 
electricity grid and developed options for compliance that are cost-
effective and that provide substantial flexibility for the affected 
EGUs that will accommodate the parties charged with maintaining the 
reliability of electrical power. A key feature of the proposed federal 
plan and model trading rule is that the flexibility inherent in both of 
the two approaches (i.e., rate-based or mass-based trading) enables the 
EPA and the states to create a level of flexibility for affected EGUs 
that allows owners and operators to determine the best way to achieve 
emission reductions, at the EGU-, state-, multi-state-, regional-, or 
national level. As a result, compliance strategies can mirror, or be 
integrated with, the ongoing operations of the current electricity grid 
as it continues to serve its primary critical function of ensuring an 
uninterrupted supply of affordable and reliable electricity. This 
flexibility is especially valuable whenever the need to address 
specific reliability concerns arises. It allows owners and operators of 
reliability-critical EGUs to continue to meet their compliance 
obligations while operating to maintain electric reliability.
    The EPA outlined and initiated the Clean Energy Incentive Program 
(CEIP) in the final EGs (see section VIII of the final EGs). The 
program is designed to

[[Page 64970]]

incentivize investment in certain types of renewable energy (RE) 
projects, as well as demand-side energy efficiency (EE) projects 
implemented in low-income communities, that generate MWh or reduce end-
use energy demand during 2020 and/or 2021. The EPA proposes to apply 
the CEIP in all states subject to either a rate-based or mass-based 
federal plan.
    We also reviewed impacts that this action could have on the 
environment and the need to ensure environmental integrity of the 
program as well as avoid unintended environmental impacts. We took 
measures to ensure that the reductions in carbon emissions this plan 
will achieve are real, and not just apparent. As in the EGs, in both 
the rate- and mass-based approaches, the EPA has incorporated 
components to address the concern that the dynamics of either a rate- 
or mass-based trading program could incentivize shifting generation 
from existing units in ways that would result in more CO2 
emissions than would otherwise be expected, or that undermine the 
purpose of the CAA section 111(d) program.
    We considered whether compliance choices under a federal plan could 
lead to an unintended concentration of other air pollutants in certain 
overburdened communities, particularly low-income communities and 
communities of color. As discussed below, our analysis shows why we do 
not expect this to occur at any significant level. In general, as in 
the EGs, we anticipate that the federal plan will result in overall 
reductions of co-pollutants, in addition to reductions in 
CO2, with corresponding co-benefits to public health. We 
also reviewed whether this action could trigger an obligation to 
consult with other agencies responsible for implementing the Endangered 
Species Act, and propose to conclude that it will not.
    In the final EGs, the EPA emphasized the importance of state 
actions to ensure that in developing their respective compliance plans 
the states addressed the concerns and priorities of vulnerable 
communities. In the process of developing a final federal plan, the EPA 
will take actions to address those concerns as well. In addition to the 
public hearings that the EPA will be holding for all members of the 
American public on this proposed rulemaking, we will also be conducting 
a national webinar and outreach meeting(s) in all ten regions on this 
proposed rulemaking for communities. The goal of these outreach 
activities is to provide communities with the information they need to 
understand how the proposed rulemaking will potentially impact their 
respective communities. At the same time, this information will be 
useful in helping communities engage the EPA during our comment period, 
as well as with their states during the state plan development process. 
We will also be providing other outreach and support activities for 
vulnerable communities, which are outlined in the community and 
environmental justice (EJ) considerations in section IX.B of this 
preamble.

B. Organization and Approach for This Proposed Rule

    In this action, the EPA is proposing a federal plan to implement 
the Clean Power Plan EGs for affected fossil fuel-fired EGUs operating 
in states that do not have approved state plans. Specifically, the EPA 
is co-proposing two different approaches to a federal plan to implement 
the Clean Power Plan EGs--a rate-based trading approach and a mass-
based trading approach. While establishing emission standards for 
affected EGUs that would be directly enforceable against the owners and 
operators of the source, both approaches would grant EGUs substantial 
flexibility in meeting their compliance obligations. For this reason, 
among others, these proposed approaches also serve as two proposed 
model trading rules that states may adopt or tailor in designing their 
own plans.
    The EGs provide that states have until September 6, 2016 (or upon 
making an initial submittal, until September 6, 2018) to submit state 
plans, and the EPA does not intend to finalize and implement the 
federal plan for any states prior to the agency's action of determining 
a failure to submit a state plan or disapproving a state plan. At the 
same time, in order to support states' consideration of adoption of one 
of the model trading rules as an approvable state plan, the agency 
intends to finalize either or both model rule options presented in this 
proposed rule by summer 2016, prior to the deadline for state 
submittals.
    The EPA currently intends to finalize a single approach--i.e., 
either a rate-based or a mass-based approach--in all promulgated 
federal plans for particular states in order to enhance the consistency 
of the federal trading program, achieve economies of scale through a 
single, broad trading program, ensure efficient administration of the 
program, and simplify compliance planning for affected EGUs. The EPA 
recognizes that the mass-based trading approach would be more 
straightforward to implement compared to the rate-based trading 
approach, both for industry and for the implementing agency. The EPA, 
industry, and many state agencies have extensive knowledge of and 
experience with mass-based trading programs. The EPA has more than two 
decades of experience implementing federally-administered mass-based 
emissions budget trading programs including the Acid Rain Program (ARP) 
sulfur dioxide (SO2) trading program, the Nitrogen Oxides 
(NOX) Budget Trading Program, CAIR, and CSAPR. The tracking 
system infrastructure exists and is proven effective for implementing 
such programs. The EPA requests comment on which approach--mass-based 
or rate-based trading--is preferred for the federal plan. Some 
stakeholders have suggested there could be utility in the availability 
of both approaches based on the unique circumstances of particular 
states. The EPA recognizes that it remains potentially possible to 
finalize a different approach to a federal plan in some circumstances, 
but believes that in general, and consistent with prior federal trading 
programs such as CSAPR, creating a single, broad program has the most 
advantages.
    The stringency of the proposed federal plan is the same as the 
CO2 emission performance rates established for affected EGUs 
in the EGs. As explained in the final EGs, the EPA determined the 
CO2 emission performance rates through the application of 
the BSER. In the EGs, the EPA has taken final action on the BSER for 
CO2 emissions from existing fossil fuel-fired EGUs. Any 
comments on this proposed rule relating to the BSER, its stringency, 
rationale, or legal basis, will not be considered as, by definition, 
they will be beyond the scope of this action.\3\
---------------------------------------------------------------------------

    \3\ The agency recognizes that the ``remaining useful lives'' of 
facilities subject to a CAA section 111(d) federal plan is a factor 
that it must consider at the time it implements the federal plan. 
This factor, and how the agency proposes to consider it, is 
discussed in section III.G of this preamble below.
---------------------------------------------------------------------------

1. The Rate-Based Approach
    In the first approach, the EPA would implement a rate-based 
emissions trading program. In a rate-based program, affected EGUs must 
meet an emission standard, derived from the EGs, expressed as a rate of 
pounds of CO2 per megawatt hour (lbs/MWh). If sources emit 
above their assigned rate, they must acquire a sufficient number of 
emission rate credits (ERC), each representing a zero-emitting megawatt 
hour (MWh), to bring their rate of emissions into compliance. Emission 
rate credits (ERCs) may be generated by affected EGUs or by other 
entities that supply zero- or low-emitting electricity resources to the 
grid through an approval and recognition process that

[[Page 64971]]

the EPA will administer. ERCs may be bought and sold, or banked for use 
in later years. The rate-based approach is explained in greater detail 
in section IV of this preamble.
2. The Mass-Based Approach
    The second approach to a federal plan that the EPA is proposing in 
this action is a mass-based trading program. In a mass-based program, 
the EPA would create a state emissions budget equal to the total tons 
of CO2 allowed to be emitted by the affected EGUs in each 
state, consistent with the mass goals established in the EGs. The EPA 
would initially distribute the allowances within each state budget--
less three proposed allowance set-asides--to the affected EGUs based on 
their historical generation. Allowances may then be transferred, 
bought, and sold on the open market, or banked for future use. The 
compliance obligation on each of the affected EGUs is to surrender the 
number of allowances sufficient to cover the EGU's respective emissions 
at the end of a given compliance period. The EPA is also proposing as a 
part of the mass-based approach three set-asides of allowances: (1) For 
a Clean Energy Incentive Program; (2) to support renewable energy (RE) 
projects; and (3) to allocate allowances based on an updating 
measurement of affected-EGU generation. The EPA is also proposing that 
a jurisdiction may choose to replace the federal plan allocation 
provisions with its own allowance allocation provisions. The mass-based 
approach is explained in greater detail in section V of this preamble.
3. Other Proposed Actions
    The EPA is proposing in this action a finding that it is necessary 
or appropriate to regulate affected EGUs in certain parts of Indian 
country via a federal plan. This is discussed in section VI.D of this 
preamble.
    In this action, the EPA is also proposing a number of changes to 
the framework CAA section 111(d) regulations of 40 CFR part 60, subpart 
B. These changes generally are intended to provide enhancements to the 
process for state plan submissions and the timing of EPA actions 
related to state plans and the federal plan. Specifically, the EPA 
proposes six changes, to include: (1) Partial approval/disapproval 
mechanisms similar to CAA section 110(k)(3); (2) a conditional approval 
mechanism similar to CAA section 110(k)(4); (3) a mechanism for the EPA 
to make calls for plan revisions similar to the ``SIP-call'' provisions 
of CAA section 110(k)(5); (4) an error correction mechanism similar to 
CAA section 110(k)(6); (5) completeness criteria and a process for 
determining completeness of state plans and submittals similar to CAA 
section 110(k)(1) and (2); and (6) updates to the deadlines for EPA 
action. These proposed changes are explained in greater detail in 
section VII of this preamble. They are not a component of the proposed 
federal plan, or changes in the EGs. If these changes are finalized, 
they will be applicable to other CAA section 111(d) rules. The EPA 
intends to finalize these changes earlier than the finalization of the 
model trading rules.

C. Who does the Proposed Action apply to?

    Regulated Entities. Existing fossil fuel-fired EGUs (or affected 
EGUs) covered by the final Clean Power Plan that are located in a state 
that does not have an EPA-approved state plan are potentially subject 
to this proposed action. Affected EGUs are those that were in 
operation, or had commenced construction, on or before January 8, 
2014.\4\ The following North American Industrial Classification System 
(NAICS) codes apply as shown in Table 1 of this preamble:
---------------------------------------------------------------------------

    \4\ An affected EGU is any fossil fuel-fired EGU that was in 
operation or had commenced construction as of January 8, 2014, and 
is therefore an ``existing source'' for purposes of CAA section 111, 
but in all other respects would meet the applicability criteria for 
coverage under the GHG standards for new fossil fuel-fired EGUs.

    This table is not intended to be exhaustive, but rather provides a 
general guide for identifying entities likely to be affected by the 
proposed action. Whether an affected EGU is affected by this action is 
described in the applicability criteria in 40 CFR 60.5845 and 60.5850 
of subpart UUUU. Questions regarding the applicability of this action 
to a particular entity should be directed to the person listed in the 
preceding FOR FURTHER INFORMATION CONTACT section of this preamble.
1. What is an affected electric utility generating unit?
    For the federal plan, the definition of an affected EGU is 
identical to the definition in the final Clean Power Plan. 
Additionally, the applicability of the federal plan is consistent with 
the EGs, where an affected EGU subject to the federal plan is any steam 
generating unit (SGU), integrated gasification combined cycle (IGCC), 
or stationary combustion turbine (SCT) that was in operation or had 
commenced construction as of January 8, 2014,\5\ and that meets certain 
criteria, which differ depending on the type of unit. The criteria to 
be an affected EGU are as follows: A unit, if it is a SGU or IGCC, must 
serve a generator capable of selling greater than 25 MW (Megawatts) to 
a utility power distribution system, have a base load rating greater 
than 260 GJ/h (250 MMBtu/h) heat input of fossil fuel (either alone or 
in combination with any other fuel), and historically have supplied 
more than \1/3\ of its potential electric output and 219,000 MWh as 
net-electric sales on any 3 calendar year basis. If a unit is a SCC, 
the unit must meet the definition of a combined cycle or combined heat 
and power (CHP) combustion turbine, serve a generator capable of 
selling greater than 25 MW to a utility power distribution system, have 
a base load rating of greater than 260 GJ/h (250 MMBtu/h), and 
historically have combusted more than 90 percent natural gas on a heat 
input basis on an annual basis.
---------------------------------------------------------------------------

    \5\ January 8, 2014 is the date the proposed GHG standards of 
performance for new fossil fuel-fired EGUs were published in the 
Federal Register (79 FR 1430).

---------------------------------------------------------------------------

[[Page 64972]]

2. How To Determine if a Unit Is Covered By an Approved and Effective 
State Plan
    Section 111(d) of the CAA, as amended, 42 U.S.C. 7411(d), 
authorizes the EPA to develop and implement a federal plan for affected 
EGUs upon the EPA's action finding a failure to submit or disapproving 
a state plan.\6\ The affected EGUs covered in EPA-approved state plans 
are not subject to the federal plan. If the federal plan has been put 
in place in a state, but is later replaced by an EPA-approved state 
plan, the affected EGUs would become subject to the state plan as of 
the effective date specified in a Federal Register notice regarding the 
EPA's approval of the state plan. The EPA is not expecting state plans 
to be submitted by the states that submit negative declarations. 
However, in the event that there are later determined to be affected 
EGUs located in these states, the final federal plan would be applied 
to such EGUs through a future action. Part 62 of title 40 of the CFR 
identifies the status of approval and promulgation of CAA section 
111(d) state plans for designated facilities in each state. Recognizing 
the urgent need for actions to reduce GHG emissions, and in accordance 
with the Presidential Memorandum,\7\ as well as the benefit of 
providing states with model trading rule options to consider as they 
prepare their state plans, the EPA is proposing this rulemaking 
concurrently with the Administrator's signing and promulgation of the 
final Clean Power Plan EGs. 40 CFR part 62 is updated only once per 
year. Thus, if 40 CFR part 62 does not indicate that your state has an 
approved and effective plan after the compliance date has passed 
requiring state plan submittal, you should contact your state 
environmental agency's Air Director or your EPA Regional Office (see 
Table 2 in section II.B of this preamble) to determine if approval 
occurred since publication of the most recent version of 40 CFR part 
62.
---------------------------------------------------------------------------

    \6\ In this Preamble, the term ``state'' generally encompasses 
the 50 states and the District of Columbia, U.S. territories, and 
any Indian Tribe that has been approved by the EPA pursuant to 40 
CFR 49.9 as eligible to develop and implement a CAA section 111(d) 
plan. However, the federal plan is not proposed for affected EGUs in 
certain states or territories where the EGs did not finalize 
emission performance rates.

II. Background Information

A. What is the regulatory development background for this proposed 
rule?

    On August 3, 2015, the EPA finalized the Clean Power Plan EGs for 
existing fossil fuel-fired EGUs (40 CFR part 60, subpart UUUU) under 
authority of section 111 of the CAA (79 FR 34950). The Guidelines apply 
to existing fossil fuel-fired EGUs, i.e., those that were in operation 
or had commenced construction before January 8, 2014. States with 
existing EGUs subject to the EGs are required to submit to the EPA by 
September 6, 2016, a state plan that implements the EGs. States may 
also make initial plan submittals in lieu of a complete state plan, in 
which case extensions will be granted until September 6, 2018 (40 CFR 
part 60, subpart UUUU).\8\ As discussed in section VI.D of this 
preamble, Indian Tribes may, but are not required to, submit tribal 
plans. Once the EPA finds that a state has failed to submit a plan, or 
disapproves a state plan,\9\ section 111 of the CAA and 40 CFR 60.27 
require the EPA to develop, implement, and enforce a federal plan for 
existing EGUs located in that state. In addition, CAA section 301(d)(2) 
authorizes the Administrator to treat an Indian Tribe in the same 
manner as a state for this EGU requirement. See 40 CFR 49.3; see also 
``Indian Tribes: Air Quality Planning and Management,'' hereafter 
``Tribal Authority Rule,'' (63 FR 7254, February 12, 1998). As 
discussed in section VI.D of this preamble, the agency in this action 
is proposing a necessary or appropriate finding for the affected EGUs 
in several areas of Indian country and is proposing the federal plan 
for these affected EGUs.
---------------------------------------------------------------------------

    \8\ See section VII of this preamble for additional information 
on proposed changes to 40 CFR 60.27 to provide enhancements and 
flexibilities to the agency's process for review and action on state 
plans and promulgation of federal plans.
    \9\ If a state has submitted a complete plan, then the EPA will 
go through a public notice and comment process to fully or partially 
approve or disapprove the state plan.
---------------------------------------------------------------------------

    The agency believes it is appropriate to propose the federal plan 
at this time for any states that may ultimately be found to have failed 
to submit a plan, or had their plan disapproved by the EPA. For some 
states in this situation, the federal plan may be no more than an 
interim measure to ensure that congressionally mandated emission 
standards under authority of section 111 of the CAA are implemented 
until they can get an approved plan in place. Other states may choose 
to rely on the federal plan and would not need to develop their own 
plan. This proposal also serves as two proposed model trading rules 
which states can adopt or tailor for adoption as their state plan. The 
role of the model rules is discussed in section II.B of this preamble.
    In this proposal, the EPA is soliciting public comment only on the 
proposed approaches for a federal plan and model trading rule for the 
implementation of the Clean Power Plan EGs. Comments on the underlying 
Clean Power Plan rule will be considered outside the scope for this 
proposed rule.

B. What is the purpose of this proposed rule?

    The purpose of this action is two-fold: (1) To co-propose two 
approaches to a

[[Page 64973]]

federal plan to implement the Clean Power Plan EGs for affected EGUs 
operating in any state lacking an approved state plan by the relevant 
deadlines; and (2) to propose these same approaches as model trading 
rules for states to consider in developing their own plans.
1. Federal Plan
    Section 111 of the CAA and 40 CFR 60.27 require the EPA to develop, 
implement and enforce a federal plan to cover existing EGUs located in 
states that do not have an approved plan. Section 111(d) of the CAA 
relies upon states as the preferred implementers of EGs for existing 
EGUs. States with affected EGUs are to submit state plans or make 
initial submittals to the EPA by September 6, 2016 pursuant to the 
EGs.\10\ States without any existing EGUs are directed to submit to the 
Administrator a letter of negative declaration certifying that there 
are no affected EGUs in the state. No plan is required for states that 
do not have any affected EGUs. Affected EGUs located in states that 
mistakenly submit a letter of negative declaration will become subject 
to the federal plan until a state plan covering those EGUs becomes 
approved. The EPA intends to finalize the federal plan only for those 
states that the EPA finds failed to submit plans or whose plans the EPA 
disapproves. For more information on the timing and mechanics of EPA 
action on state plans and finalization of this federal plan, see 
section II.D of this preamble below.
---------------------------------------------------------------------------

    \10\ States may request extensions of up to two years as part of 
a complete initial CAA section 111(d) submission.
---------------------------------------------------------------------------

2. Model Trading Rule
    The EPA is also proposing the federal plan approaches as two forms 
of a model trading rule (mass-based and rate-based), which states can 
adopt or tailor for implementation as a state plan under the EGs. The 
EPA intends to finalize the model trading rules earlier than it 
promulgates a federal plan for a state. When the EPA finalizes one or 
both of its proposed approaches as a final model trading rule, and a 
state adopts a final model trading rule in its entirety as its state 
plan, it would be presumptively approvable.
    The EPA has designed these rules so that they meet the requirements 
of the final EGs. If one of the model rules is adopted by a state 
without any change, it would be presumptively approvable. We use the 
term ``presumptively'' in recognition that a state plan submission must 
be accompanied by other materials in addition to the regulatory 
provisions. These requirements are set forth in the final Clean Power 
Plan and framework regulations of 40 CFR part 60, subpart B. For 
instance, they include a formal letter of submittal from the Governor 
or his or her designee, evidence that the rule has been adopted into 
state law and that the state has necessary legal authority to implement 
and enforce the rule, and evidence that procedural requirements, 
including public participation under 40 CFR 60.23, have been met.
    In further support of state use of the model rules, we are drafting 
the model trading rule so that it can be adopted or incorporated by 
reference with a minimum of changes that would be necessary to make the 
rule appropriate for use by states. This way, a state may incorporate 
by reference the model rule as the state plan, or as the backstop to a 
state measures plan with few if any adjustments. States may make 
changes to the model trading rule, so long as they still meet the 
requirements of the EGs. If the state chooses to tailor or modify the 
model trading rule such as by expanding the scope of eligibility of 
projects that may generate ERCs in a rate-based trading program, the 
EPA may still approve the plan, but the EPA would conduct appropriate 
review of such provisions for consistency with the EGs and the state 
would have to demonstrate to the EPA's satisfaction that its 
alternative provisions are as stringent as the presumptively approvable 
approach described. We note here, and in the regulatory text of the 
model trading rule, that the scope of eligibility of proposed ``ERC 
resources'' for the federal plan is different than the scope of 
eligibility provided for in the model rule. Thus, all of the language 
and provisions in the regulatory text relevant to these other ERC 
resources is relevant only to the proposed model trading rule and not 
to the federal plan as such (i.e., those ERC resources discussed in 
section IV.C.3 of this preamble are applicable to the model rule and 
only metered RE and applicable nuclear are applicable to the federal 
plan).
    The EPA's approval of a state plan, including a plan that adopts 
the model trading rule, will be the result of an independent notice-
and-comment rulemaking process. Without prejudging the outcome of that 
process, the EPA recognizes that it may be able to approve or 
``conditionally approve'' state plans that are substantially similar, 
but not identical to, the final model trading rules. Ultimately, state 
plans must meet the requirements of the EGs for approvability. Thus, a 
conditional approval would be based on a condition that the state take 
such actions as may be necessary by a date certain to meet the 
requirements of the EGs. (The EPA is proposing to explicitly provide 
for conditional approvals in the CAA section 111(d) framework 
regulations. See section VII.B of this preamble.)
    In accordance with the EGs, the process for review and approval (or 
disapproval) of state plans, whether based on the model trading rules 
or otherwise, would occur once the states have made their submissions 
by September 6, 2016. As provided in the EGs, states have the option of 
not submitting a full state plan, but rather making an initial 
submittal, in order to obtain an extension of 2 years before submitting 
a full state plan for EPA approval. It could be beneficial for 
coordination purposes if a state that is interested in adopting one of 
the model trading rules but intends to make an initial submittal next 
year were to indicate which model trading rule they intend to adopt. 
This is not an additional requirement beyond what the EGs require for 
initial submittals, however.
    The EPA strongly encourages states to consider adopting one of the 
model trading rules, which are designed to be referenced by states in 
their rulemakings. Use of the model trading rules by states would help 
to ensure consistency between and among the state programs, which is 
useful for the potential operation of a broad trading program that 
spans multi-state regions or operates on a national scale. As discussed 
at length in the EGs, EGUs operate less as individual, isolated 
entities and more as multiple components of a large interconnected 
system designed to integrate a range of functions that ensure an 
uninterrupted supply of affordable and reliable electricity while also, 
for the past several decades, maintaining compliance with air pollution 
control programs. Since, as a practical matter under both the EGs and 
any federal plan, emission reductions must occur at the affected EGUs, 
a broad-scale emissions trading program would be particularly effective 
in allowing EGUs to operate in a way that achieves pollution control 
without disturbing the overall system of which they are a part and the 
critical functions that this system performs. In addition, consistency 
of requirements benefits the affected EGUs, as well as the states and 
the EPA in their roles as administrators and implementers of a trading 
program. States of course remain free to develop a plan of their own 
choosing to submit to the EPA for approval following the

[[Page 64974]]

criteria set out in the final Clean Power Plan EGs.
    The EPA believes there are compelling policy reasons that support 
the provision of a proposed model trading rule at this time. The EPA 
has heard from multiple stakeholders and in public comments submitted 
on the proposed EGs that there is a strong interest in seeing a model 
state plan or trading rule prior to the deadline for state submittals 
under the EGs. According to these stakeholders, model rules can provide 
predictability for planning purposes, both among states and affected 
EGUs. In addition, some states have indicated that they may prefer to 
rely on a federal plan, either temporarily or permanently, rather than 
develop a plan of their own. This proposal of a model trading rule 
addresses these policy interests.
    The approach of proposing model trading rules that are identical in 
all key respects to proposed federal plans that may be promulgated 
later, is consistent with prior CAA section 111(d) and CAA section 110 
rulemakings. For example, the NOX state implementation plan 
(SIP) Call model rule at 40 CFR part 96 (63 FR 57356; October 27, 1998) 
was identical in all meaningful respects with the Federal 
NOX Budget Trading Program at 40 CFR part 97 (65 FR 2674; 
January 18, 2000). And the CAIR model rule in 40 CFR part 96 (70 FR 
25339; May 12, 2005) was identical in all meaningful respects with the 
federal CAIR in 40 CFR part 97 (71 FR 25396; April 28, 2006).\11\ While 
these identical programs for model rules and Federal Implementation 
Plans (FIPs) were finalized in separate parts of the CFR, the EPA does 
not see any reason that it could not just as easily propose the federal 
plan as the model trading rule in the same section of the CFR.\12\ If a 
federal plan were to be finalized for a given state at a later time, 
this would be reflected in 40 CFR part 62 by cross-reference, along 
with any modifications or adjustments that may be appropriate at the 
time of actual promulgation of a federal plan.
---------------------------------------------------------------------------

    \11\ We also note that historically under the CAA section 
111(d)/129 rules, the content of EGs and their corresponding federal 
plans have had significant overlap.
    \12\ We propose to include a note in the regulatory text 
explaining where aspects of the proposed subpart relevant to states 
as part of the model trading rule are not applicable.

----------------------------------------------------------------------------------------------------------------

C. Legal Authority

    Section 111(d)(2) of the CAA, 42 U.S.C. 7411(d)(2) provides the EPA 
the same authority to prescribe a plan for a state in cases where the 
state fails to submit a satisfactory plan as the agency would have 
under CAA section 110(c) in the case of failure to submit an 
implementation plan. In addition, the EPA has authority under CAA 
section 111(d)(1) to prescribe regulations that establish procedures 
similar to CAA section 110 with respect to the submission of state 
plans, and the EPA also has general rulemaking authority as necessary 
to implement the CAA under CAA section 301. A federal plan under CAA 
section 111(d) applies, implements and enforces standards of 
performance for affected EGUs. Under the Clean Power Plan EGs, state 
plans will be due on September 6, 2016, but states are also allowed to 
seek a 2-year extension for a final plan submittal, upon a satisfactory 
initial plan submittal by the same deadline. See 40 CFR 60.5755, 
60.5760(b). If a state does not submit a final state plan or initial 
plan submittal,\13\ or if either a final state plan or an initial plan 
submittal does not meet the requirements of the EG, the agency will 
take the appropriate steps to finalize and implement a federal plan for 
that state's EGUs.
---------------------------------------------------------------------------

    \13\ Indeed, states may simply choose to accept a federal plan 
in lieu of undertaking to develop a state plan at all. While the 
statute uses the phrase ``fails to submit a satisfactory plan,'' the 
EPA does not believe this should carry any pejorative connotation. 
While Congress identified states and local governments as having 
``primary responsibility'' for air pollution prevention and control, 
CAA section 101(a)(3), states are in no way penalized for not 
submitting a plan under CAA section 111(d). Rather, the EPA steps 
into the shoes of the state to carry out the CAA section 111(d) 
program in its stead. To the extent states may be interested in 
accepting a federal plan, the EPA would be interested in hearing 
that through the comment process on this proposal.
---------------------------------------------------------------------------

    Further, states will remain free, and indeed are strongly 
encouraged, to submit an approvable state plan even after promulgation 
of the federal plan for their jurisdictions. The EPA will withdraw the 
federal plan for a state when that state submits, and the EPA approves, 
a final plan. See 40 CFR 60.5720.

D. Timing of EPA Actions on the Model Trading Rules, Federal Plan, and 
Other Proposed Actions

    This action co-proposes two approaches to the federal plan, both of 
which also constitute proposed model trading rules that states could 
adopt as state plans for EPA approval. The EPA currently intends to 
finalize one or both of the model trading rules by next summer so that 
they may be available to states as soon as possible to help inform 
their state plan development efforts prior to the initial submittal 
deadline of September 6, 2016, and 2 years before the states' final 
plan deadline of September 6, 2018.\14\ If the EPA

[[Page 64975]]

finalizes the model trading rules in that timeframe, the only direct 
consequence will be to provide the states certainty as to one or two 
particular approaches to the design of their state plan that the EPA 
will approve if adopted in full. The finalization of a model trading 
rule will not constitute a final action with respect to a federal plan 
for the affected EGUs in any state. Rather, the proposed federal plan 
will remain just that, a proposal. The EPA will promulgate a final 
federal plan for any state only after it has made a finding on a 
state's failure to submit a plan, or fully or partially disapproved a 
submitted state plan. The EPA will go through a public notice and 
comment process before disapproving a submitted and complete state 
plan, in whole or part. The EPA invites comments on this staged 
approach to finalizing one or more model trading rules on the one hand 
(which we currently intend to do in summer 2016), and finalizing 
federal plans on the other (which we currently intend to do state-by-
state upon our taking predicate action on states' plans).
---------------------------------------------------------------------------

    \14\ We anticipate that the model rules' text could be finalized 
either in a new subpart or subparts of 40 CFR part 62 of title 40 of 
the CFR as proposed, or in a final document that is not published in 
the CFR.
---------------------------------------------------------------------------

    In this action, the EPA is also proposing enhancements to the 
process for agency action on state submittals and promulgation of a 
federal plan under CAA section 111(d). For more detailed discussion of 
these changes, see section VII of this preamble. This aspect of this 
proposal is separate from the federal plan and the model trading rules. 
The EPA intends to finalize these changes on a timeline earlier than 
both a model trading rule and the federal plan.
    Under the framework regulations as proposed to be amended, see 
section VII below, and the final EGs, at 40 CFR 60.27 and 60.5715 and 
5760, respectively, the initial timelines for EPA action on state 
submittals and, potentially, the promulgation of a federal plan will be 
as follows: The EPA will have 12 months from the date of a state's 
submission to approve or disapprove that state's plan. The EPA will 
have 12 months from the date of its action on a state submission to 
promulgate the federal plan for the EGUs in that state. Under the 
completeness-criteria process proposed to be added to 40 CFR 60.27, see 
section VII.E below, the EPA would have 6 months from the deadline for 
a state's submission to notify a state that its submittal does not meet 
completeness criteria and constitutes a failure to submit a plan. In 
the case of initial submittals under 40 CFR 60.5765, the EPA will have 
90 days from the date the EPA received the initial submittal to notify 
a state that its initial submittal does not meet the requirements of 40 
CFR 60.5765(a). As with state plans, the EPA will have 12 months to 
promulgate a federal plan from the date of its finding that a state 
failed to submit a complete and approvable initial submittal. 
(Formally, such a finding would be that the state failed to submit a 
state plan.)
    The timeframes stated in the previous paragraph reflect the maximum 
time allowed for EPA action. We note that under CAA section 111(d)(2) 
and CAA section 110(c), the EPA may promulgate a final federal plan for 
a state immediately upon making a finding of failure to submit a state 
plan or initial submittal, or upon making a finding of final 
disapproval of a state plan. Congress gave the EPA authority in CAA 
section 111(d)(2), as it did in CAA section 110(c), to promulgate a 
federal plan at any time after it disapproves or finds a failure to 
submit a state plan. The Supreme Court has recognized that under this 
authority, the EPA may promulgate a FIP ``at any time'' within the 2-
year limit of CAA section 110(c) ``that begins the moment EPA 
determines a SIP to be inadequate.'' EME Homer City v. EPA, 134 S. Ct. 
1584, 1601 (2014). ``EPA is not obliged to wait two years or postpone 
its action even a single day . . . .'' Id. It is essential to implement 
plans for the control of emissions of CO2 expeditiously and 
avoid unnecessary delay. Among other reasons, this will provide 
affected EGUs regulatory certainty and will assist the regulated 
entities as well as those authorities with responsibility for ensuring 
grid reliability to have as much time as possible to plan for the 2022 
compliance start date set in the EGs. Thus, it is reasonable to propose 
this federal plan now so that federal plans will be ready to be 
promulgated quickly in cases where states have failed to submit a plan 
or their plans are found unsatisfactory.
    It is the agency's intention to promulgate federal plans promptly 
for states who do not submit plans or initial submittals by September 
6, 2016. However, the effect of putting the federal plan in place at 
that time would ultimately be limited in impact upon states. Because 
the EPA would implement the federal plan, its promulgation does not 
obligate state officials to take any actions themselves. Further, 
states remain free--and the EPA in fact encourages states--to submit 
state plans that can replace the federal plan. States can do so in 
advance of the beginning of the performance period in 2022, or may 
transfer to a state plan after that date. However, in doing so, the 
agency and states should be mindful of the goals of regulatory 
certainty discussed in the prior paragraph.
    Because we are proposing a federal plan that would apply emission 
standards to affected EGUs in all states that the agency determines not 
to have an approvable plan, the EPA invites comment from all persons 
with concerns about or comments on the proposed federal plan as it may 
apply in any state, whether or not that state has submitted, or intends 
to submit, its own plan on which the EPA has yet to take action.
    In this document, the EPA is proposing regulatory text setting out 
the substantive provisions for both of the proposed federal plans/model 
trading rules. The EPA is not providing specific regulatory text that 
would, if finalized, actually promulgate a federal plan for each state 
for which this proposed federal plan might be applied.\15\ We currently 
envision that this language would be in the form of a new section to 
the state-specific subparts of part 62 and would be ministerial in 
nature. It would likely provide that the affected EGUs in each such 
state are subject to a federal plan and would then cross-reference or 
incorporate by reference the substantive provisions of one of the two 
subparts proposed in this action (if finalized), along with any 
applicable modifications or adjustments as may be necessary, either 
based on new information or in response to comments regarding the 
application of the federal plan to that particular state. This text may 
appear similar to the FIP language found in the final CSAPR rule (76 FR 
48208, 48361-78; August 8, 2011).
---------------------------------------------------------------------------

    \15\ The minimum contents of a notice of proposed rulemaking 
under the CAA are set forth at CAA section 307(d)(3) and 5 U.S.C. 
553(b).
---------------------------------------------------------------------------

E. Use of the Model Trading Rule as a Backstop

    As discussed in the final EGs, the EPA believes that either a mass-
based or rate-based model trading rule could function well as the 
federally enforceable ``backstop'' that the EGs require to be included 
in ``state measures'' type state plans.\16\ (The proposed federal plan 
does not itself require a ``backstop'' because it relies on an 
``emission standards'' approach, rather than a ``state measures'' 
approach, as delineated in the final EGs.) The conditions and 
requirements for the federally enforceable backstop in a state measures 
approach are discussed in

[[Page 64976]]

detail in the final EGs. See sections VIII.C.3.b and VIII.C.6.c of the 
final EGs. To summarize those provisions, without reopening them for 
comment, the federally enforceable backstop must fully achieve the 
CO2 emission performance rates or the state's interim and 
final CO2 emission goals if the state plan fails to achieve 
the intended level of CO2 emission performance. The state 
plan submittal must identify the federally enforceable emission 
standards for affected EGUs that would be used in the backstop, 
demonstrate that those emission standards meet the requirements that 
apply in the context of an emission standards approach, identify a 
schedule and trigger for implementation of the backstop that is 
consistent with the requirements in the EGs, and identify all necessary 
state administrative and technical procedures for implementing the 
backstop (e.g., how and when the state would notify affected EGUs that 
the backstop has been triggered). In addition, the backstop emission 
standards must make up for any shortfall in CO2 emission 
performance during a prior plan performance period that led to 
triggering of the backstop.
---------------------------------------------------------------------------

    \16\ We are aware of at least one case in which a court has 
upheld the use of a trading program as a backstop to ensure CAA 
requirements are met. See WildEarth Guardians v. U.S. EPA, No. 12-
9596 (10th Cir. filed October 21, 2014) (upholding use of backstop 
cap-and-trade program under 40 CFR 41.309 of the Regional Haze 
Rule).
---------------------------------------------------------------------------

    The EGs explicitly recognized that the backstop emission standards 
could be based on one of the model trading rules that the EPA is 
proposing in this action. As discussed in section II.B of this preamble 
above, we are drafting the model trading rule so that it can be adopted 
or incorporated by reference with a minimum of changes necessary to 
make the rule appropriate for use by states, and this includes its use 
as a backstop. Instances of this approach are throughout the proposed 
rule text and reflect our desire to ease the use of the model rule for 
states, as a full state plan, or as a backstop to a ``state measures'' 
plan.
    One way in which a backstop may need to differ from the model 
trading rules proposed in this action is the requirement to make up for 
a shortfall in emissions performance in a state's prior plan 
performance period. The model trading rules do not provide provisions 
that would automatically adjust the emission standards to account for 
any prior emission performance shortfall (which is an option states 
have if designing their own backstop). Thus, a state relying on the 
model trading rule as its backstop would likely need to submit an 
appropriate revision to the backstop emission standards adjusting for 
the shortfall through the state plan revision process. This would 
likely be done in conjunction with the process for putting the backstop 
into effect.
    If a state chooses to use the model rule as its federally 
enforceable backstop in a state measures plan, this does not mean that 
the backstop is itself the federal plan. Rather, the model rule becomes 
adopted as a part of the state plan. Both approaches to the model 
trading rule are ``emission standard'' approaches under the EGs where 
an emission standard is imposed and federally enforceable on the 
affected EGUs: In the rate-based approach the emissions standard is an 
allowable rate of emissions; in the mass-based approach the emission 
standard is the requirement to hold allowances equal to reported 
emissions. The EPA may also handle the administration of the trading 
program for states utilizing the model trading rule. However, even 
though the backstop may take the form of an EPA-administered, 
federally-enforceable trading rule, this does not mean that a federal 
plan has been put into effect. The state retains all of its rights and 
responsibilities with respect to the implementation and enforcement of 
the backstop as a component of its state plan.
    Applicability and Enforceability. If promulgated for the affected 
EGUs in a particular state, this federal plan will require affected 
EGUs to meet specific emission standards for CO2 and related 
requirements. These enforceable compliance obligations will apply to 
the owners and operators of those affected EGUs. See 40 CFR 62.13. No 
obligation falls on states or state officials (except to the extent 
they may be owners and operators of affected EGUs).\17\ In the event of 
noncompliance, the provisions in the federal plan are federally 
enforceable against an affected EGU, in the same manner as the 
provisions of an approved state plan under CAA section 111(d), and 
similar to a FIP or an approved SIP under CAA section 110. See CAA 
section 111(d)(2)(B), 42 U.S.C. 7411(d)(2)(B) (power to enforce state 
and federal plans), section 113(a)-(h), 42 U.S.C. 7413(a)-(h), and 
section 304, 42 U.S.C. 7604. This means that the Administrator has the 
ability to enforce against violations and secure appropriate corrective 
actions pursuant to CAA sections 113(a)-(h), and states and other third 
parties maintain the ability to enforce against violations and secure 
appropriate corrective actions pursuant to CAA section 304.
---------------------------------------------------------------------------

    \17\ See Reno v. Condon, 528 U.S. 141, 151 (2000). State 
officials responsible for developing state plans, however, should be 
aware of the procedural enhancements being proposed to the framework 
regulations of 40 CFR part 60, subpart B, in this rulemaking 
document. These changes are discussed in section VII of this 
preamble below. These changes are not a component of the proposed 
federal plan or the EGs. Although these changes do not alter the 
deadlines or submission obligations provided in the Clean Power Plan 
Emission Guidelines, state officials and other interested parties 
are encouraged to review and comment on these changes.
---------------------------------------------------------------------------

III. Federal Plan Structure To Achieve Reductions

A. Overview

1. Interactions With State Plans and Scope of Trading
    The EPA intends to set up and administer a program to track trading 
programs--both rate-based and mass-based--that will be available for 
all states that choose it. The EPA proposes that affected EGUs in any 
state covered by a federal plan could trade compliance instruments with 
affected EGUs in any other state covered by a federal plan or a state 
plan meeting the conditions for linkage to the federal plan. In the 
proposed mass-based federal plan trading program, this would mean that 
affected EGUs in a state covered by the federal plan or a state meeting 
the conditions for linkage to the federal plan could use, as a 
compliance instrument, an allowance distributed in any other state 
covered by the federal plan or a state meeting the conditions for 
linkage to the federal plan. Similarly, in the proposed rate-based 
federal plan trading program approach, this would mean that affected 
EGUs in a state covered by the federal plan or a state meeting the 
conditions for linkage to the federal plan could use, as a compliance 
instrument, an ERC issued in any other state covered by the federal 
plan or a state meeting the conditions for linkage to the federal plan. 
We propose that an affected EGU in a state covered by the mass-based 
trading federal plan must use allowances for compliance (not ERCs). 
Similarly, an affected EGU in a state covered by the rate-based trading 
federal plan must use ERCs for compliance (not allowances).
    The agency promulgated provisions for ``ready-for-interstate-
trading'' plans in the EGs. The EPA is proposing the federal plans as 
ready-for-interstate-trading plans. State plans that adopt the model 
rule are also considered ready-for-interstate-trading. The EPA proposes 
to allow interstate trading between affected EGUs in states covered by 
the proposed federal plans and affected EGUs in states covered by state 
plans (referred to below as ``linking'' states, or ``linkages'') under 
the following conditions, which are discussed further below the list:
     The state plan must be approved.
     The state plan must implement the same type of trading 
program as the federal plan trading program in order to

[[Page 64977]]

be linked for interstate trading, i.e., mass-based trading programs can 
link to mass-based trading programs only, and rate-based trading 
programs can link to rate-based trading programs only.
     The state plan must use the identical compliance 
instrument as the federal plan (this requirement is detailed below).
     The state plan must be approved as a ready-for-interstate-
trading plan.
     The state plan must use an EPA-administered tracking 
system (we are also requesting comment on expanding this to include a 
state plan that uses an EPA-designated tracking system that is 
interoperable with an EPA-administered system, as detailed below).
    The EPA proposes that interstate ERC trading could occur both (1) 
from affected EGUs in states covered by the rate-based trading federal 
plan to affected EGUs in states with approved rate-based trading state 
plans meeting the proposed conditions for linkages (including the 
conditions for being ``ready-for-interstate-trading'' that were 
finalized in the EG), and (2) from affected EGUs in such state-plan-
covered states to affected EGUs in federal-plan-covered states. The EPA 
also requests comment on expanding the scope of interstate trading to 
include linking states covered by the rate-based trading federal plan 
with any state that has an approved rate-based trading state plan 
meeting the proposed conditions for linkages and that uses an EPA-
designated ERC tracking system that is interoperable with an EPA-
administered ERC tracking system. The EPA also requests comment on 
allowing a state that has an approved rate-based trading state plan 
meeting the proposed conditions for linkages and that uses an EPA-
designated ERC tracking system to register with the EPA, and after 
registration, to link with states covered by the rate-based trading 
federal plan. There are multiple benefits to a registration 
requirement, which include ensuring that the tracking systems are 
functionally interoperable.
    For the mass-based federal plan, the EPA proposes that interstate 
allowance trading could occur in both directions, i.e., from affected 
EGUs in states covered by the mass-based trading federal plan to 
affected EGUs in states with approved mass-based trading state plans 
meeting the proposed conditions for linkages, and from affected EGUs in 
such state-plan-covered states to sources in federal-plan-covered 
states.
    The EPA proposes that a condition of linkage between a state plan 
and the federal plan is the use of an identical compliance instrument. 
In the mass-based federal plan the EPA proposes to issue allowances in 
short tons; as a result, the EPA is proposing in this rule that linkage 
for the mass-based federal plan is limited to state plans that issue 
allowances in short tons. The agency also requests comment on whether 
to extend linkage to state plans that issue allowances in metric tons 
and on what provisions would be necessary to implement such linkages. 
The EPA believes that considerations for linkages to state plans that 
use metric tons may include tracking system design, and stipulation of 
which parties convert state plan allowances denominated in metric tons 
to allowances denominated in short tons and at what stage of compliance 
operations the conversion occurs. The agency requests comment on these 
and any other considerations for linkages between the federal plan and 
state plans that issue allowances in metric tons.\18\
---------------------------------------------------------------------------

    \18\ In this preamble all references to ``tons'' are short tons, 
unless otherwise noted.
---------------------------------------------------------------------------

    The EPA also requests comment on expanding the scope of interstate 
trading to include linking states covered by the mass-based trading 
federal plan with any state that has an approved mass-based trading 
state plan meeting the proposed conditions for linkages and that uses 
an EPA-designated allowance tracking system that is interoperable with 
an EPA-administered allowance tracking system. The EPA also requests 
comment on allowing a state that has an approved mass-based trading 
state plan meeting the proposed conditions for linkages and that uses 
an EPA-designated allowance tracking system to register with the EPA, 
and after registration, to link with states covered by the mass-based 
trading federal plan.
    In the Clean Power Plan EGs, the EPA promulgated requirements that 
apply to an emissions budget trading state plan that includes non-
affected EGU emission sources, to provide the opportunity for such a 
state plan to be potentially approvable for linking to other state 
plans (see Clean Power Plan EGs, section VIII). In this proposed rule, 
the proposed approach to link from the mass-based trading federal plan 
to state plans could result in linking of the federal plan to state 
plans that include non-affected emission sources. The EPA requests 
comment on this proposed approach.
    The EPA believes that a broad trading region provides greater 
opportunities for cost-effective implementation of reductions compared 
to trading limited to a smaller region. The proposed approach to 
interstate trading is intended to strike a reasonable balance between 
providing the opportunity for a wide interstate trading system while 
maintaining the integrity of the linked programs. The agency requests 
comment on the proposed approach to interstate trading linkages in the 
federal plans.
    Whether the EPA ultimately finalizes rate-based or mass-based 
federal plans, the agency believes that the ERC market and the 
allowance market would be competitive. The opportunities for interstate 
trading detailed above would reduce any potential for firms to exercise 
market power in the ERC market or allowance market. The EPA requests 
comment on this expectation of a competitive ERC market and a 
competitive allowance market, and comment on potential program design 
choices that could address any identified market power concern. The EPA 
intends to provide information to the market and the public, consistent 
with other trading programs that the agency administers, as detailed in 
sections IV and V of this preamble, for the rate-based and mass-based 
approaches, respectively.
    A transparent and well-functioning allowance or ERC market is an 
important element of a mass-based or rate-based trading program. The 
EPA has over 20 years of experience implementing emissions trading 
programs for the power sector and based on that experience, believes 
the potential or likelihood of market manipulation is fairly low. 
Nonetheless, the EPA is evaluating the options for providing oversight 
of the allowance or ERC markets that may be established through the 
final EGs and federal plans. This could include engaging with other 
federal and state agencies as appropriate, and potentially with third 
parties, in conducting market oversight. The agency requests comment on 
appropriate market monitoring activities, which may include tracking 
ownership of allowances or ERCs, oversight of the creation and 
verification of credits, and tracking market activity (e.g., 
transaction volumes and prices).
2. Addressing Potential Leakage and Interstate Effects
    The final EGs specify the concern of leakage, which is defined in 
section VII.D of the final EGs as the potential of an alternative form 
of implementation of the BSER (e.g., the rate-based and mass-based 
state goals) to create a larger incentive for affected EGUs to shift 
generation to new fossil fuel-fired EGUs relative to what would occur 
when the implementation of the BSER took the form of standards of 
performance incorporating the subcategory-specific emission performance 
rates representing

[[Page 64978]]

the BSER. The final EGs specified that mass-based plan approaches must 
address leakage, because the form of the mass goals may ultimately 
impact the relative incentives to generate and emit at affected EGUs as 
opposed to shifting generation to new sources, with potential 
implications for whether the mass goal implements or is consistent with 
the BSER and overall emissions from the sector. These circumstances are 
much less likely to be present under a rate-based plan approach, where 
the form of the goal ensures sufficient incentive to affected existing 
EGUs to generate and thus avoid leakage, similar to the CO2 
emission performance rates. By requiring mass-based plan components 
that address leakage, the final EGs ensure that mass goals are 
equivalent to the CO2 emission performance rates and are 
thus an equivalent expression of the BSER. Section VII.D of the final 
EGs details the requirement for addressing leakage and why it is 
needed, and section VIII.J of the final EGs specifies options for mass-
based state plan components that address leakage. We are proposing, as 
part of the mass-based approach under the federal plan and model rule, 
to implement allowance allocation approaches to address leakage, 
specifically through establishing an output-based allocation set-aside 
and a set-aside that encourages the installation of RE. These proposed 
strategies are detailed in section V.D of this preamble.
    In the final EGs, the EPA also discussed the concern that 
CO2 emission reductions would be eroded in situations where 
an affected EGU in a rate-based state counts the MWh from measures 
located in a mass-based state, but the generation from that measure 
acts solely to serve load in the mass-based state. In that scenario, 
expected CO2 emission reduction actions in the rate-based 
state are foregone as a result of counting MWh that resulted in 
CO2 emission reductions in a mass-based state. The proposed 
rate-based approach, in accordance with the final EGs, restricts ERC 
issuance for any emission reduction measures located in a mass-based 
state, except for RE. RE measures located in a state with a mass-based 
state plan can only be approved for ERC issuance for use by a state 
under a rate-based federal plan if it can be demonstrated that load-
serving entities in the rate-based state have contracted for the 
delivery of the RE generation that occurs in a mass-based state to meet 
load in a rate-based state. As part of this federal plan, we are 
proposing that this can be demonstrated through the provision of a 
power delivery contract or power purchase agreement in which an entity 
in the rate-based state contracts for the supply of the MWhs in 
question and providing documentation that the electricity was treated 
as comparable to a generation resource used to serve regional load that 
included the rate-based state. This demonstration must be included as 
part of the project application for ERC issuance to the EPA or its 
agent from the RE provider in the mass-based state. Once the project is 
approved, subsequent applications for issuance of credit to the EPA 
will need to reference that the MWh submitted are associated with that 
contractual arrangement with the mass-based RE provider. The EPA 
requests comment on this approach. It should also be noted that we are 
proposing that under the proposed mass-based approach, if RE located in 
a mass-based state receives mass-based set-aside allowances for any 
generation, that generation is not eligible to be issued ERCs in a 
rate-based state.
    The EPA requests comment on the proposed treatment of leakage and 
of interstate effects under both the proposed rate-based federal plan 
approach and the proposed mass-based federal plan approach, and as part 
of the corresponding proposed model rules.
3. Provisions To Encourage Early Action
    The EPA outlined and initiated the CEIP in the final EGs (see 
section VIII.B.2 of the final EGs). The program is designed to 
incentivize investment in certain types of RE projects, as well as 
demand-side energy efficiency (EE) projects implemented in low-income 
communities. These RE projects must commence construction, and these EE 
projects must commence implementation after the date of submission of a 
final plan to the EPA by the state they are located on or benefitting, 
or after September 6, 2018 for those states on whose behalf the EPA is 
implementing the federal plan, and will receive incentives for the MWh 
they generate or the end-use energy demand reductions they achieve 
during 2020 and/or 2021. The CEIP also provides an additional incentive 
to drive investment in demand-side EE projects implemented in low-
income communities. The EPA proposes to apply the CEIP in all states 
subject to either a rate-based or mass-based federal plan. The EPA's 
proposed approaches to implementing the program in the rate-based and 
mass-based federal plans are detailed in sections IV and V of this 
preamble, respectively.

B. Inventory of Emissions

    Fossil fuel-fired EGUs are by far the largest emitters of GHGs 
among stationary sources in the United States, primarily in the form of 
CO2, and among fossil fuel-fired EGUs, coal-fired units are 
by far the largest emitters. This section describes the amounts of 
these emissions and places these amounts in the context of the U.S. 
Inventory of Greenhouse Gas Emissions and Sinks \19\ (the U.S. GHG 
Inventory).
---------------------------------------------------------------------------

    \19\ ``Inventory of U.S. Greenhouse Gas Emissions and Sinks: 
1990-2013'', Report EPA 430-R-15-004, United States Environmental 
Protection Agency, April 15, 2015. http://www.epa.gov/climatechange/ghgemissions/usinventoryreport.html.
---------------------------------------------------------------------------

    The EPA implements a separate program under 40 CFR part 98 called 
the Greenhouse Gas Reporting Program \20\ (GHGRP) that requires 
emitting facilities over threshold amounts of GHGs to report their 
emissions to the EPA annually. Using data from the GHGRP, this section 
also places emissions from fossil fuel-fired EGUs in the context of the 
total emissions reported to the GHGRP from facilities in the other 
largest-emitting industries.
---------------------------------------------------------------------------

    \20\ U.S. EPA Greenhouse Gas Reporting Program Dataset, see 
http://www.epa.gov/ghgreporting/ghgdata/reportingdatasets.html.
---------------------------------------------------------------------------

    The EPA prepares the official U.S. GHG Inventory to comply with 
commitments under the United Nations Framework Convention on Climate 
Change (UNFCCC). This inventory, which includes recent trends, is 
organized by industrial sectors. It provides the information in Table 3 
of this preamble, which presents total U.S. anthropogenic emissions and 
sinks \21\ of GHGs, including CO2 emissions, for the years 
1990, 2005, and 2013.
---------------------------------------------------------------------------

    \21\ Sinks are a physical unit or process that stores GHGs, such 
as forests or underground or deep sea reservoirs of CO2.

    In addition to preparing the official U.S. GHG Inventory, which 
represents comprehensive total U.S. GHG emissions and complies with 
commitments under the UNFCCC, the EPA collects detailed GHG emissions 
data from the largest emitting facilities in the United States through 
its GHGRP. Data collected by the GHGRP from large stationary sources in 
the industrial sector show that the utility power sector emits far 
greater CO2 emissions than any other industrial sector. 
Table 5 of this preamble presents total GHG emissions in 2013 for the 
largest emitting industrial sectors as reported to the GHGRP. As shown 
in Table 4 and Table 5 of this preamble, respectively, CO2 
emissions from fossil fuel-fired EGUs are nearly three times as large 
as the total reported GHG emissions from the next ten largest emitting 
industrial sectors in the GHGRP database combined.

C. Affected EGUs

    For the Clean Power Plan and this federal plan, an affected EGU is 
any SGU, IGCC, or stationary combustion turbine that was in operation 
or had commenced construction as of January 8, 2014,\28\ and that meets 
the following criteria, which differ depending on the type of unit. To 
be an affected EGU, such a unit, if it is SGU or IGCC, must serve a 
generator capable of selling greater than 25 MW to a utility power 
distribution system and have a base load rating greater than 260 GJ/h 
(250 MMBtu/h) heat input of fossil fuel (either alone or in combination 
with any other fuel). If such a unit is a SCT, the unit must meet the 
definition of a combined cycle or CHP combustion turbine, serve a 
generator capable of selling greater than 25 MW to a utility power 
distribution system, and have a base load rating of greater than 260 
GJ/h (250 MMBtu/h).
---------------------------------------------------------------------------

    \27\ U.S. EPA Greenhouse Gas Reporting Program Dataset as of 
August 18, 2014. http://ghgdata.epa.gov/ghgp/main.do.
    \28\ Under section 111(a) of the CAA, determination of affected 
sources is based on the date that the EPA proposes action on such 
sources. January 8, 2014 is the date the proposed GHG standards of 
performance for new fossil fuel-fired EGUs were published in the 
Federal Register (79 FR 1430).
---------------------------------------------------------------------------

    When considering and understanding applicability, the following 
definitions may be helpful. Simple cycle

[[Page 64980]]

combustion turbine means any stationary combustion turbine which does 
not recover heat from the combustion turbine engine exhaust gases for 
purposes other than enhancing the performance of the stationary 
combustion turbine itself. Combined cycle combustion turbine means any 
SCT which recovers heat from the combustion turbine engine exhaust 
gases to generate steam that is used to create additional electric 
power output in a steam turbine. CHP combustion turbine means any SCT 
which recovers heat from the combustion turbine engine exhaust gases to 
heat water or another medium, generates steam for useful purposes other 
than exclusively for additional electric generation, or directly uses 
the heat in the exhaust gases for a useful purpose.
    We note that certain affected EGUs are exempt from inclusion in a 
state plan and this federal plan. Affected EGUs that may be excluded 
under the EGs are those that (1) Are subject to subpart 40 CFR part 60, 
subpart TTTT as a result of commencing modification or reconstruction; 
(2) are SGUs or IGCC that are currently and always have been subject to 
a federally enforceable permit limiting net-electric sales to one-third 
or less of its potential electric output or 219,000 MWh or less on an 
annual basis; (3) are non-fossil units (i.e., units that are capable of 
combusting 50 percent or more non-fossil fuel) that have historically 
limited the use of fossil fuels to 10 percent or less of the annual 
capacity factor or are subject to a federally enforceable permit 
limiting fossil fuel use to 10 percent or less of the annual capacity 
factor; (4) are stationary combustion turbines that are not capable of 
combusting natural gas (i.e., not connected to a natural gas pipeline); 
(5) are CHP units that are subject to a federally enforceable permit 
limiting, or have historically limited, annual net electric sales to a 
utility power distribution system to the product of the design 
efficiency and the potential electric output or 219,000 MWh (whichever 
is greater) or less; (6) serve a generator along with other SGU(s), 
IGCC(s), or stationary combustion turbine(s) where the effective 
generation capacity (determined based on a prorated output of the base 
load rating of each SGU, IGCC, or stationary combustion turbine) is 25 
MW or less; (7) are a municipal waste combustor unit subject to subpart 
Eb of 40 CFR part 60; or (8) are a commercial or industrial solid waste 
incineration unit that is subject to subpart CCCC of 40 CFR part 
60.\29\
---------------------------------------------------------------------------

    \29\ We had proposed in the Clean Power Plan EGs that affected 
EGUs were those existing source fossil fuel-fired EGUs that met the 
applicability criteria for coverage under the final GHG standards 
for new fossil fuel-fired EGUs being promulgated under CAA section 
111(b). However, we are finalizing in the EGs that states need not 
include certain units that would otherwise meet the CAA section 
111(b) applicability in this CAA section 111(d) EGs. These include 
simple cycle turbines, certain non-fossil units, and certain CHP 
units. The final CAA section 111(b) standards include applicability 
criteria for simple cycle combustion turbines, for reasons relating 
to implementation and minimizing emissions from all future 
combustion turbines.
---------------------------------------------------------------------------

    The EPA also requests comment on an alternative compliance pathway 
that could be available to units under a mass-based approach. The ways 
that the approach could be implemented are further outlined in the 
Alternative Compliance Pathway for Units that Agree to Retire Before a 
Certain Date Technical Support Document (TSD). Under this approach, two 
basic requirements would need to be met. The first is that the unit 
would have to take a commitment that it would retire on a date on or 
before December 31, 2029. The second is that the unit would have to 
demonstrate that it will take an enforceable emission limitation that 
would assure that the overall state emission goal is met. The TSD 
explores ways that this approach could be implemented, including ways 
that the enforceable emission limitation could be calculated and 
implemented. The EPA requests comment on whether this approach should 
be available for all units or limited to small units (e.g. less than 
100 MW nameplate capacity). The EPA also requests comment on whether 
and how such an approach could be included under a rate-based approach.
    The applicability of this proposed federal plan follows the same 
applicability criteria as the final EGs. The rationale for these 
criteria is provided in section IV.D of the Clean Power Plan. We are 
not reopening the criteria or rationale here.
    In the federal plan Affected EGU TSD, the EPA lists all applicable 
affected EGUs according to our records from the National Electric 
Energy Data System (NEEDS), Energy Information Administration (EIA), 
and comments from the Clean Power Plan. In this TSD, each affected EGU 
is assigned its proposed applicable standards if a federal plan were to 
be promulgated for that affected EGU at any time. The EPA requests 
comments and updates to this list of affected units. Section VI.C of 
the final EGs describes the data used in setting the standards and how 
an inventory of affected units has been compiled.

D. Compliance Schedule

    In accordance with the schedule set out in the EGs, the federal 
plan is proposed to be implemented in a phased approach. The first 
period, corresponding to the Interim Period in the EG, is proposed to 
run from beginning of calendar year 2022 until end of calendar year 
2029 (January 1, 2022 to December 31, 2029). The Final Period would run 
from beginning of calendar year 2030 (January 1, 2030) indefinitely 
into the future. The first period is proposed to be comprised of three 
``compliance periods,'' set by calendar year. The first compliance 
period will be from January 1, 2022 to midnight, December 31, 2024 (3 
calendar years). The second compliance period will be from January 1, 
2025 to midnight, December 31, 2027 (3 calendar years). The third 
compliance period will be from January 1, 2028 to midnight, December 
31, 2029 (2 calendar years).
    Under the EGs, midnight, December 31, 2029 marks the end of the 
Interim Period, and the beginning of the Final Period. The EPA proposes 
that the compliance periods in the Final Period will each be 2 calendar 
years. Thus, the first compliance period after 2030 would be from 
January 1, 2030 to midnight, December 31, 2031. The second compliance 
period would be from January 1, 2032 to midnight, December 31, 2033. 
This would repeat accordingly unless changed by the EPA through a 
revision to the federal plan or other action.\30\
---------------------------------------------------------------------------

    \30\ This schedule would be the same under either a rate- or 
mass-based approach.
---------------------------------------------------------------------------

    The EPA recognizes that the compliance periods provided for in this 
rulemaking are longer than those historically and typically specified 
in CAA rulemakings. As reflected in long-standing CAA precedent, 
``[t]he time over which [the compliance standards] extend should be as 
short term as possible and should generally not exceed one month.'' See 
e.g., June 13, 1989 Guidance on Limiting Potential to Emit in New 
Source Permitting and January 25, 1995 Guidance on Enforceability 
Requirements for Limiting Potential to Emit through SIP and Sec.  112 
Rules and General Permits. The EPA determined that the longer 
compliance periods provided for in this rulemaking are acceptable in 
the context of this specific rulemaking because of the unique 
characteristics of this rulemaking, including that CO2 is 
long-lived in the atmosphere, and this rulemaking is focused on 
performance standards related to those long-term impacts.

    Prior to the beginning of the first compliance period in 2022, the 
agency intends to establish the infrastructure for operating a federal 
trading program and to work closely with affected EGUs in the states 
where the federal plan is promulgated prior to the start of the first 
compliance period in 2022. We request comment on whether it would be 
possible to grant, on a case-by-case basis, certain affected EGUs, 
particularly small entities, additional time to come into compliance, 
and to request additional input from the public as to the design of 
such flexibility that would be compatible with the EGs and a federal 
plan that implements a trading system.
    The EPA recognizes that it is important to ensure a degree of 
liquidity in compliance instruments in either of the proposed trading 
approaches, while also maintaining the stringency required by the final 
EGs. A number of aspects of the rate-based and mass-based programs 
would assist with this, including allocation methods or rules, 
mechanisms to place allowances or credits into the market relatively 
early, requirements for public transparency of information related to 
allowance, or credit issuance, tracking, transfers and holdings. The 
EPA solicits comment on other approaches to ensure market liquidity 
while continuing to meet the stringency of the final EGs.

E. Addressing Reliability Concerns

    The proposed federal plan has been designed to ensure that, to the 
greatest extent possible, implementation would not interfere with the 
power sector's ability to maintain electric reliability.\31\ Like the 
EGs, the federal plan provides a long planning horizon and 
implementation period. In addition the federal plan allows affected 
EGUs to obtain tradable allowances and credits to meet obligations 
which assures that reliability can be maintained without disruption to 
the electricity system.
---------------------------------------------------------------------------

    \31\ The EPA evaluated certain aspects of electric reliability 
in the context of modeling projections for the final Clean Power 
Plan, and that evaluation is described in the ``Resource Adequacy 
and Reliability Analysis TSD'' for that rulemaking, a copy of which 
is also included in the docket for this rulemaking.
---------------------------------------------------------------------------

    There are many features of the electricity system that ensure that 
electric system reliability will be maintained. For example, in the 
Energy Policy Act of 2005, Congress added a section to the Federal 
Power Act to make reliability standards mandatory and enforceable by 
the Federal Energy Regulatory Commission (FERC) and the North American 
Electric Reliability Corporation (NERC), the Electric Reliability 
Organization which FERC designated and oversees. Along with its 
standards development work, NERC conducts annual reliability 
assessments via a 10-year forecast and winter and summer forecasts; 
audits owners, operators and users for preparedness; and educates and 
trains industry personnel. Numerous other entities such as FERC, U.S. 
Department of Energy (DOE), state public utility commissions (PUCs), 
independent system operators and regional transmission organizations 
(ISOs/RTOs), and other planning authorities also consider the 
reliability of the electric system. There are also numerous remedies 
that are routinely employed when there is a specific local or regional 
reliability issue. These include transmission system upgrades, 
installation of new generating capacity, calling on demand response, 
and other demand-side actions.
    Additionally, planning authorities and system operators constantly 
consider, plan for and monitor the reliability of the electricity 
system with both a long-term and short-term perspective. Over the last 
century, the electric industry's efforts regarding electric system 
reliability have become multidimensional, comprehensive and 
sophisticated. Under this approach, planning authorities plan the 
system to assure the availability of sufficient generation, 
transmission, and distribution capacity to meet system needs in a way 
that minimizes the likelihood of equipment failure.\32\ Long-term 
system planning happens at both the local and regional levels with all 
segments of the electric system needing to operate together in an 
efficient and reliable manner. In the short-term, electric system 
operators operate the system within safe operating margins and work to 
restore the system quickly if a disruption occurs.\33\ Mandatory 
reliability standards apply to how the bulk electric system is planned 
and operated. For example, transmission operators and balancing 
authorities have to develop, maintain and implement a set of plans to 
mitigate operating emergencies.\34\

---------------------------------------------------------------------------

    The EPA's approach in this proposed federal plan builds on the 
foundation provided in the EGs' determination of the BSER to ensure 
that the final federal plan, like the final EGs, does not interfere 
with the industry's ability to maintain reliability of the nation's 
electricity supply. First, the federal plan, like the EGs, provides 
more than 6 years before reductions are required and an 8-year period 
from 2022 to 2029 to meet interim goals. This allows time for planning 
and steady, measured implementation.
    Second, the federal plan is a market-based trading program which 
will allow affected EGUs the opportunity to buy and sell emissions 
credits or allowances as well as bank them. The EPA's proposed federal 
plan includes two alternative approaches: A mass-based trading program 
and a rate-based trading program. Trading programs of both types have 
many positive attributes. Among them is that they help to ensure that 
imposition of the federal plan will not interfere with the industry's 
ability to maintain the reliability of the nation's electricity supply. 
Such a program does not restrict unit-level operational decision-making 
beyond requiring units to hold a sufficient number of tradable permits 
(e.g., allowances or ERCs) to cover emissions. It, therefore, 
inherently allows for unit-level operational flexibility to facilitate 
the maintenance of reliability and makes the program enormously 
resilient. If a unit finds it needs to run more than anticipated, the 
market-based compliance system provides a way for the EGU to meet its 
generation needs while it maintains compliance with the federal plan.
    Third, just as we have required the states to do in developing 
state plans, the EPA is considering reliability as a part of developing 
this federal plan. For example, the EPA will consult with planning 
authorities. The EPA will work with the ISO/RTO Council to convene a 
face-to-face meeting for planning authorities with the EPA during the 
comment period to discuss any concerns or other feedback on the federal 
plan from those entities. This meeting will help to ensure that the EPA 
is taking into consideration any concerns about the relationship of 
this rulemaking to the ability of the industry to maintain electric 
reliability across the country as we finalize the federal plan. It will 
give the planning authorities an opportunity to hear directly from the 
EPA how the federal plan is designed and gives the planning authorities 
an opportunity to voice concerns and ask questions. This will help 
inform comments that planning authorities may submit to the docket.
    In the final Clean Power Plan EGs, the EPA laid out the 
availability of a reliability safety valve that could be used if an 
unanticipated catastrophic emergency caused a conflict between

[[Page 64982]]

maintenance of electric reliability and inflexible requirements that a 
state plan might impose on an affected EGU or EGUs. Under the federal 
plan, inflexible requirements are not imposed on specific plants. 
Rather as explained earlier, the very nature of the federal plan, in 
which affected EGUs can obtain allowances or credits if needed, 
supports reliability. Therefore, a reliability safety valve for the 
federal plan is not needed. The EPA invites comments on this aspect of 
the proposed federal plan.
    The EPA, DOE, and FERC have agreed to coordinate efforts to help 
ensure continued reliable electricity generation and transmission 
during the implementation of the final EGs and the final federal plan 
in any state that does not have an approved state plan. The three 
agencies have developed a coordination strategy that reflects their 
joint understanding of how they will work together to monitor 
implementation. The three agencies will work together to monitor 
implementation, share information and resolve any difficulties that may 
be encountered.
    The EPA is not proposing to include an allowance set-aside, or 
similar mechanism in a rate-based approach, to address reliability 
issues in the federal plan; however, we request comment on including 
such a set-aside in the context of a mass-based approach. The EPA 
requests comment specifically on creation of an allowance set-aside for 
the purpose of making allowances available in emergency circumstances 
in which an affected EGU was compelled to provide reliability critical 
generation and demonstrated that a supply of allowances needed to 
offset its emissions was not available.
    The set-aside would be in addition to the proposed set-asides that 
are detailed in section V.D in this preamble. The EPA would set aside 
allowances in each state under the mass-based federal plan, and if a 
reliability issue is perceived by the EPA, DOE and FERC coordinated 
monitoring process discussed above, the EPA would distribute allowances 
from the set-aside to support affected EGUs during or after an 
unforeseen, emergency reliability event. If there were unused 
allowances remaining in the set-aside, then the EPA would distribute 
them to affected EGUs pro rata based on the allocation approach that is 
detailed in section V.D of this preamble. The EPA requests comment on 
all elements of such an approach, including what events would trigger 
the need for allowances from the reliability set-aside; eligibility 
criteria to receive the set-aside allowances; the size of the set-
aside; and the timing of distribution of allowances from the 
reliability set-aside. Additionally, the EPA requests comment on how a 
reliability ``set-aside'' approach could be implemented in the rate-
based federal plan.
    As detailed later in this preamble, the EPA proposes in the federal 
plan to implement a CEIP, which was established in the EGs to reward 
investment in certain clean energy projects that achieve MWh results 
during 2020 and 2021 (see sections IV and V of this preamble for the 
proposed approach to implement this incentive program in the rate-based 
and mass-based federal plans, respectively). Implementation of the CEIP 
in the federal plans would create ERCs and allowances before 2022, 
allowing for creation of banks that could be used in the event of an 
unforeseen, emergency reliability issue. The EPA requests comment on 
the potential for these banks of ERCs and allowances to support 
reliable electricity generation and transmission to be utilized in the 
event of this kind of reliability emergency.

F. Worker Certification

    In the EGs, the EPA suggested that to ensure that emission 
reductions are realized, it is important that construction, operations 
and other skilled work undertaken pursuant to state plans is performed 
to specifications, and is effective, safe, and timely. The EPA asks for 
comments as to whether the federal plan should encourage EGUs to ask 
for a demonstration that the work undertaken under a federal plan is 
performed by a proficient workforce. A good way to ensure such a 
workforce is to require that workers have been certified by: (1) An 
apprenticeship program that is registered with the U.S. Department of 
Labor (DOL), Office of Apprenticeship or a state apprenticeship program 
approved by the DOL; (2) a skill certification aligned with the DOE 
Better Building Workforce Guidelines and validated by a third party 
accrediting body recognized by DOE; or (3) other skill certification 
validated by a third party accrediting body.

G. Remaining Useful Lives and Potential for ``Stranded Assets''

    Section 111(d)(2) of the CAA provides, ``In promulgating a standard 
of performance under a plan prescribed under this paragraph, the 
Administrator shall take into consideration, among other factors, 
remaining useful lives of the sources in the category of sources to 
which such standard applies.'' 42 U.S.C. 7411(d)(2). This language 
tracks similar language in CAA section 111(d)(1) with respect to state 
plans. In the final EGs, we explained how the Guidelines permit states 
in applying a standard of performance in their state plans to consider 
the remaining useful life of a facility. We determined that it was 
appropriate to specify that the general variance provisions in 40 CFR 
60.24(f) should not apply to the class of affected facilities covered 
by these Guidelines. We concluded that facility-specific factors and in 
particular, remaining useful life, do not justify a state making 
further adjustments to the performance rates or aggregate emission goal 
that the Guidelines define for affected EGUs in a state and that must 
be achieved by the state plan.
    Because the Guidelines do not allow for states to deviate from 
state goals based on remaining useful life, the EPA does not believe 
such goal adjustments are necessary or appropriate in the federal plan 
either. Nonetheless, this does not obviate the requirement that the EPA 
itself, in the design of its federal plan, consider, among other 
factors, the remaining useful lives of the affected facilities. The 
agency therefore proposes the following analysis of this factor.\35\
---------------------------------------------------------------------------

    \35\ We note that the preamble and supporting materials for the 
EGs discuss a related concern raised by some stakeholders, which is 
whether the EGs could result in widespread ``stranded assets'' as a 
direct result of the rule. As explained there, we believe this 
concern is distinct from the ``remaining useful lives'' factor in 
CAA section 111(d)(1), and for the same reasons, believe it is 
distinct from the factor Congress directed the agency to consider in 
CAA section 111(d)(2). Nonetheless, we undertook analysis in the 
final EGs of whether and to what extent there may be a ``stranded 
asset'' concern. See memorandum to Clean Power Plan Docket EPA-HQ-
OAR-2013-0602 titled ``Stranded Assets Analysis'' dated July 2015. 
We believe that analysis demonstrates that this is not likely to be 
a widespread issue under the federal plan either.
---------------------------------------------------------------------------

    Congress added the ``remaining useful lives'' factor to CAA section 
111(d)(2) in the 1977 CAA Amendments. Congress did not provide in the 
statute any direction on how or to what degree ``remaining useful 
lives'' of facilities subject to a section 111(d) federal plan is to be 
considered. As discussed in the preamble to the final EGs, Congress' 
intent in enacting the provision was to allow for older facilties with 
short remaining useful lives to not be required to install capital-
intensive pollution control devices to meet emission standards that 
would only be used for a short period of time before a plant ceased 
operation. A House of Representatives report on a predecessor bill to 
the enacted statute stated, ``Older plants with relatively short 
remaining useful lives might have chosen to cease operation if the only 
means of emission

[[Page 64983]]

limitation available to meet emission limits were pollution control 
technology.'' H. Report 94-1175, at 159 (1976) (emphasis added). This 
language is probative of the fact that Congress viewed ``remaining 
useful lives'' as a consideration for facilities with relatively little 
remaining useful life. We are confident the proposed federal plan will 
not force costly pollution control investments at older plants with 
short remaining useful lives.
    Further, the statute provides that this factor is one ``among other 
factors'' that the agency is to consider in promulgating a standard of 
performance. Congress provided no guidance in the statute as to what 
those other factors could be. The inclusion of unspecified factors that 
the agency may determine for itself to consider, along with the use of 
the term ``consider,'' highlights that Congress intended to give the 
agency a substantial degree of discretion in determining how the 
``remaining useful lives'' factor is considered. The statute does not 
require, and Congress did not intend, that this consideration mandate 
the agency to prevent all premature retirements of affected EGUs, to 
impose no emission requirements on older affected EGUs, or to ensure 
that profitability is maintained at all times for all affected EGUs. 
Congress knew how to explicitly exempt older plants from CAA 
requirements at the time of the 1977 Amendments. For example, Congress 
excluded plants in existence before August 7, 1977 from the 
preconstruction requirements of the prevention of significant 
deterioration (PSD)/non-attainment new source review (NSR) program, see 
CAA section 165(a). And in CAA section 169A related to visibility 
impairment in federal class I areas, Congress excluded from 
applicability units that began operation before August 7, 1962. 42 
U.S.C. 7491(b)(2)(A). In CAA section 111(d) Congress did not set any 
such specific criteria. Rather it directed the agency to ``consider'' 
the remaining useful lives of facilities, among other factors.
    This view also accords with past agency practice in implementing a 
similar provision. In the 1977 Amendments, Congress listed ``remaining 
useful life'' as a factor for consideration in the visibility program 
under section 169A. 42 U.S.C. 7491. The ``remaining useful life of the 
source'' is one of several enumerated factors that the state or the EPA 
is to consider in determining the best available retrofit technology 
(BART) for a particular source. Consistent with congressional purpose, 
the EPA has implemented this factor in the regional haze program for 
many years through the BART guidelines, in appendix Y to 40 CFR part 
51. In the context of the visibility program, we have interpreted this 
provision to mean that the remaining useful life should be considered 
when calculating the annualized costs of retrofit controls. See 40 CFR 
part 51, appendix Y, section IV.D.4.k. In the agency's view, this 
approach to ``remaining useful life'' aligns with congressional intent 
and informs our view of how the ``remaining useful lives'' factor 
should be considered under this CAA section 111(d) federal plan. The 
key consideration is whether the time period associated with 
amortizable costs of compliance will exceed the remaining useful lives 
of the sources in question.
    Consistent with legislative intent and past agency practice, we 
propose that the federal plan adequately considers ``remaining useful 
lives'' of affected EGUs by providing for trading and other 
flexibilities authorized in the EGs. To summarize, these include: 
Relatively long periods for affected EGUs to come into compliance, the 
ability to credit early action, the use of emissions trading, the use 
of multi-year compliance periods, and the ability to link to other 
federal or state plans to create larger emissions markets. The federal 
plan is proposed to include a Clean Energy Incentive Program as 
provided for in the EGs, which will credit early action and ease 
compliance in the initial years of the program. These tools will create 
economic incentives that reward over-performance of some affected EGUs, 
and allow others to simply acquire credits or allowances to comply with 
their emission standard, thereby avoiding the need for installation of 
costly pollution controls at sources with a short remaining life.
    Thus, the proposed federal plan is designed in such a way that it 
adequately, and inherently, takes into account the remaining useful 
lives of affected EGUs. It provides substantial compliance flexibility, 
including means of avoiding the need to make extensive capital 
investments in control technologies that could not be recouped during 
the remaining useful lives of a facility.\36\ The design of the federal 
plan as a form of emission trading provides individual affected EGUs 
the flexibility to make cost-conscious compliance choices. This 
flexibility avoids or substantially diminishes any likelihood that 
compliance will be a physical impossibility or result in unreasonable 
costs.
---------------------------------------------------------------------------

    \36\ Because we believe that this is the case for all facilities 
through the basic design of the federal plan, we also can confirm, 
in line with the EGs, that the availability of variances from the 
emission standards is unnecessary in the federal plan. Under the 
general framework regulations, facility-specific variances from an 
otherwise applicable standard of performance have been potentially 
available under the application process in 40 CFR 60.27(e)(2), which 
incorporates the factors provided in 40 CFR 60.24(f) for states. 
Consistent with our view that the federal plan adequately considers 
remaining useful lives, and for the same reasons, the need for 
facility-specific variances under the circumstances of 60.24(f) 
(unreasonable costs of controls, physical impossibility of 
installation of necessary control equipment, or other factors that 
make longer compliance times or less stringent standards 
significantly more reasonable) is not expected to arise, and thus, 
the agency proposes to make 40 CFR 60.27(e) inapplicable in this 
federal plan.
---------------------------------------------------------------------------

    By relying on either rate- or mass-based emission trading, the 
proposed federal plan capitalizes on the inherent flexibility available 
through market-based techniques. In effect, under a trading program 
with repeating compliance periods, a facility with a short remaining 
useful life has a total outlay that is proportionately smaller than a 
facility with a long remaining useful life, simply because the first 
facility would need to comply for fewer compliance periods and would 
need proportionately fewer ERCs or allowances than the second facility. 
Buying ERCs or allowances as a compliance method could avoid excessive 
up-front capital expenditures that might be unreasonable for facilities 
with short remaining useful lives, and therefore addresses the 
consideration of ``remaining useful lives.'' Buying ERCs or allowances 
as a compliance method also would reduce the potential for stranded 
assets.
    In addition, the timing of the federal plan limits the immediate 
costs of compliance, particularly for facilities that have useful lives 
ending before 2022, but also for facilities that have useful lives 
ending before 2030. There are no compliance obligations for affected 
EGUs under this federal plan until 2022, when the first compliance 
period begins. At that point, the agency is following the glide path 
provided for in the EGs, which begins with relatively higher emission 
targets that will slowly strengthen over the interim performance period 
from 2022-2029 through three multi-year compliance periods. The final, 
most stringent, compliance obligation does not begin until 2030.
    Further, unlike state plans that can be more stringent under CAA 
section 116, the federal plan is no more stringent than the EGs, and, 
as explained in the EGs, the Guidelines reflect a reasonable, rather 
than a maximum possible, implementation level for each building block 
in order to establish overall goals that are achievable. As discussed 
in the

[[Page 64984]]

EGs, the BSER determined an average level of emissions achievable by 
groups of EGUs, rather than for an individual EGU. In considering the 
remaining useful lives of facilities under a federal plan, the EPA 
believes this approach to setting the emission standards, coupled with 
the ability to trade, adequately accounts for remaining useful lives of 
facilities. In essence, it allows the facilities to comply with the 
federal plan through the purchase or acquisition of ERCs or allowances, 
and to avoid the need to make costly investments in control technology 
for plants that have short remaining useful lives.\37\ For these 
reasons, the federal plan adequately considers ``remaining useful 
lives.'' We invite comment on our consideration of facilities' 
``remaining useful lives'' in the federal plan.
---------------------------------------------------------------------------

    \37\ In addition, the ability to generate ERCs for sale or to 
sell unneeded emission allowances (depending on whether in a rate- 
or mass-based system) may give some affected EGUs an economic 
incentive to take measures to reduce emissions that otherwise would 
have been uneconomical.
---------------------------------------------------------------------------

H. Implications for Other EPA Programs and Rules

1. Title V Permitting
    Under the proposed federal plan, title V permits for sources with 
affected EGUs will need to include any new applicable requirements that 
the plan places on the affected EGUs. The EPA, however, is not 
proposing any permitting requirements independent of those that would 
be required under title V of the CAA and the regulations implementing 
title V, 40 CFR parts 70 and 71.\38\ All major stationary sources of 
air pollution and certain other sources are required to apply for title 
V operating permits that include emission limitations and other 
conditions as necessary to assure compliance with applicable 
requirements of the CAA, including the requirements of an applicable 
CAA section 111(d) state plan or federal plan. CAA sections 502(a) and 
504(a), 42 U.S.C. 7661a(a) and 7661c(a). The ``applicable 
requirements'' that must be addressed in title V permits are defined in 
the title V regulations, and include requirements under CAA section 
111(d) (40 CFR 70.2 and 71.2 (definition of ``applicable 
requirement'')).
---------------------------------------------------------------------------

    \38\ Part 70 addresses requirements for title V programs 
implemented by state, local, and tribal governments, and part 71 
governs the title V program implemented by the EPA or delegate 
agencies in areas under federal jurisdiction, such as Indian 
country.
---------------------------------------------------------------------------

    The EPA anticipates that, given the nature of the units covered by 
the proposed federal plan, most of the sources at which they are 
located are already or will be subject to title V permitting 
requirements. For sources subject to title V, the requirements 
applicable to them under the proposed federal plan will be ``applicable 
requirements'' under title V and, therefore, will need to be addressed 
in the title V permits. For example, requirements under the proposed 
federal plan concerning designated representatives, monitoring, 
reporting, and recordkeeping, the requirement to either meet an 
emission rate (including through holding ERCs (rate-based approach)), 
or to hold allowances covering emissions (mass-based approach) will be 
``applicable requirements'' to be addressed in the permits.
    The EPA does not believe this approach is affected by the Supreme 
Court's decision in Utility Air Regulatory Group v. U.S. EPA, 134 S. 
Ct. 2427 (June 23, 2014). The Supreme Court held that the EPA may not 
treat GHGs as an air pollutant for purposes of determining whether a 
source is a major source required to obtain a title V operating permit. 
In accordance with that decision, the D.C. Circuit's amended judgment 
on April 10, 2015 vacated the title V regulations under review in that 
case (40 CFR 70.12 and 71.13) to the extent that they require a 
stationary source to obtain a title V permit solely because the source 
emits or has the potential to emit GHGs above the applicable major 
source thresholds. The D.C. Circuit also directed the EPA to consider 
whether any further revisions to its regulations are appropriate in 
light of UARG v. EPA, and, if so, to undertake to make such revisions. 
As the agency made clear in a memorandum to Regional Administrators 
last year, ``While the EPA will no longer apply or enforce the 
requirement that a source obtain a title V permit solely because it 
emits or has the potential to emit GHGs above major source thresholds, 
the agency does not read the Supreme Court decision to affect other 
grounds on which a title V permit may be required or the applicable 
requirements that must be addressed in title V permits.'' \39\ 
Accordingly, while the emission of GHGs alone cannot trigger the need 
for a title V permit under UARG, the EPA believes a final federal plan 
under CAA section 111(d) will create new ``applicable requirements'' in 
the form of an emission standard (either an emission rate or an 
allowance system) and related requirements for GHGs (here, 
CO2) on affected EGUs. See 40 CFR 70.2, 71.2 (definition of 
``applicable requirement'' includes ``any standard or other requirement 
under section 111 of the Act, including section 111(d)'') (emphasis 
added). Thus, an affected EGU may be required to modify its existing 
title V permit, or obtain a new permit if it does not already have one, 
if it becomes subject to an emission standard for CO2 under 
a CAA section 111(d) federal plan.

Administrator, Office of Air and Radiation, and Cynthia Giles,

---------------------------------------------------------------------------

    The title V permits program is structured to provide flexibility 
for market-based approaches, such as allowance trading programs under 
the federal plan, including flexibility to make changes under such 
programs without necessarily requiring a formal permit revision. For 
example, the title V regulations provide that a permit issued under 
title V shall include, for any ``approved * * * emissions trading or 
other similar programs or processes'' applicable to the source, a 
provision stating that no permit revision is required ``for changes 
that are provided for in the permit.'' 40 CFR 70.6(a)(8) and 
71.6(a)(8). Consistent with this provision in the title V regulations, 
the proposed federal plan regulations include a provision stating that 
no permit revision shall be required for the allocation, holding, 
deduction, or transfer of allowances once the requirements applicable 
to such allocations, holdings, deductions, or transfers of 
CO2 allowances are already incorporated in such permit. 
Consistent with title V regulations, this provision should be included 
in each title V permit for a covered source. As a result, allowances 
will be able to be traded (or allocated, held, or deducted) under the 
federal plan without a revision of the title V permit of any of the 
sources involved.
    As a further example of flexibility under title V, and consistent 
with 40 CFR 70.7(e)(2)(i)(B) and 40 CFR 71.7(e)(1)(i)(B), the EPA is 
proposing that any changes that may be required to an operating permit 
with respect to a trading program under the federal plan may be made 
using the minor permit modification procedures of the title V rules. 
The EPA proposes that such changes may include the initial changes 
needed to the title V permit to establish the applicability of the 
trading program to the source, specify the covered units, and to 
include other permit terms that may be needed for implementation, 
including the general approach for monitoring and reporting. The minor 
permit modification procedures could also be used for any subsequent 
changes

[[Page 64985]]

to permit terms that may be needed with respect to the trading program, 
although we expect such changes to be infrequent. As noted above, once 
a trading program has been established in the permit, there may be 
transactions, such as individual trades, that will require no formal 
permit modification procedures because such trading would be already 
addressed and allowed by the permit (``provided for in the permit'') 
provided the changes do not conflict with any existing terms of the 
permit. If a source wishes to make a change that would go against any 
express term of the permit, the permit must be revised to allow such a 
change before the source begins operation of the change. Under the 
implementation strategy described above, the EPA believes it would be 
unlikely that any change in trading allowances would violate a term of 
a permit, but this principle is important to keep in mind when deciding 
if a minor permit modification is appropriate with respect to operating 
a trading program in the context of a title V permit.
    The EPA believes that the approach to permitting requirements we 
are proposing here, which imposes no additional permitting requirements 
independent of title V and provides for the use of minor permit 
modification procedures, will streamline the process for sources 
already required to be permitted under title V and for permitting 
authorities. If there are any sources that would become newly subject 
to title V as a result of the requirements of this proposed federal 
plan, the initial title V permit that would be issued pursuant to 40 
CFR 70.7(a) or 71.7(a) would address the federal plan requirements, 
when finalized.
    The EPA notes that the approach to title V permitting that is being 
proposed is somewhat similar to the approach adopted in the final 
CSAPR. See 76 FR 48299-48300 (August 8, 2011). The agency recently 
issued guidance to assist permitting authorities and sources subject to 
CSAPR in incorporating CSAPR requirements into title V permits.\40\ The 
EPA invites comment on its proposed approach to permitting requirements 
for the federal plan, including whether it would be of use to develop 
guidance similar to the guidance developed for permitting under CSAPR. 
The EPA invites comment on its proposed approach to incorporating 
applicable requirements of the federal plan into title V permits and 
revising those requirements, including specifically seeking comment on 
whether all requirements should be eligible for incorporation into 
title V permits via minor modification procedures or if only a 
specified subset of such requirements should be eligible for such 
procedures.

2. Implications for New Source Review Program
    The NSR program is a preconstruction permitting program that 
requires major stationary sources of air pollution to obtain permits 
prior to beginning construction. The requirements of the NSR program 
apply both to new construction and to modifications of existing major 
sources. Generally, a source triggers these permitting requirements as 
a result of a modification when it undertakes a physical or operational 
change that results in a significant emission increase and a net 
emissions increase. NSR regulations define what constitutes a 
significant net emissions increase, and the concept is pollutant-
specific.
    In the final EGs, the EPA recognized that, as part of its CAA 
section 111(d) plan, a state may impose requirements that require an 
affected EGU to undertake a physical or operational change to improve 
the unit's efficiency that results in an increase in the unit's 
dispatch and an increase in the unit's annual emissions. If the 
emissions increase associated with the unit's changes exceeds the 
thresholds in the NSR regulations for one or more regulated NSR 
pollutants, including the netting analysis, the changes would trigger 
NSR. We noted that while there may be instances in which an NSR permit 
would be required, we expect those situations to be few.
    The EPA believes the analysis of NSR applicability is basically the 
same for sources under a CAA section 111(d) federal plan. That is, it 
is conceivable that a source under a federal plan may choose, as a 
means of compliance with either a rate-based or mass-based approach, to 
undertake a physical or operational change to improve an affected EGU's 
efficiency that results in a significant net emissions increase of a 
regulated NSR pollutant. This would trigger NSR. However, as with state 
plans, the EPA believes that these situations will be few.
    After the proposal for the Clean Power Plan was published in June 
of 2014, the U.S. Supreme Court issued its opinion in UARG v. EPA, 134 
S. Ct. 2427 (June 23, 2014). The Supreme Court held that an increase in 
GHG emissions alone cannot by law trigger the NSR requirements of the 
PSD program under section 165 of the CAA. On remand from the Court, the 
DC Circuit issued an amended judgment in Coalition for Responsible 
Regulation, Inc. v. Environmental Protection Agency, Nos. 09-1322, 10-
073, 10-1092 and 10-1167 (D.C. Cir., April 10, 2015), vacating the 
relevant regulations. Therefore, increases in emissions of GHGs alone, 
including those that may occur through actions taken at sources to 
comply with the proposed federal plan (such as may occur when an NGCC 
unit increases its operations due to generation shift from a SGU), 
cannot trigger NSR.
    The EPA will invite comment on potential scenarios in which 
affected EGUs, particularly small entities, could be subject to the 
requirements of the NSR program as a result of taking compliance 
measures under the federal plan, and any ideas for harmonizing or 
streamlining the permitting process for such sources that are 
consistent with judicial precedent. However, the EPA is not proposing 
any changes to the NSR program in this action, and the agency is not 
reopening or reconsidering any prior actions or determinations related 
to NSR in this action. Any comments related solely to the NSR program 
will be considered outside the scope of this proposed rule.
3. Interactions With Other EPA Rules
    Existing fossil fuel-fired EGUs, such as those covered in this 
proposal, are or will be potentially impacted by several other rules 
recently finalized or proposed by the EPA.\41\ These rules include the 
Mercury and Air Toxics Standards (MATS) (77 FR 9304; February 16, 
2012); \42\ the CSAPR; Requirements for Cooling Water Intake Structures 
at Power Plants (79 FR 48300; August 15, 2014); Disposal of Coal 
Combustion Residuals from Electric Utilities, promulgated on April 17, 
2015 (80 FR 21302); and the

[[Page 64986]]

proposed Steam Electric Effluent Limitation Guidelines and Standards 
(78 FR 34432; June 7, 2013). These rules are discussed in more detail 
in the final EGs along with steps the EPA is taking to enable 
compliance with obligations under other power sector rules as 
efficiently as possible. We solicit comment on whether there are 
specific things the EPA can do in the design and implementation of the 
federal plan that further this objective.
---------------------------------------------------------------------------

    \41\ We discuss other rulemakings solely for background 
purposes. The effort to coordinate rulemakings is not a defense to a 
violation of the CAA. Sources cannot defer compliance with existing 
requirements because of other upcoming regulations.
    \42\ The Supreme Court recently reversed and remanded a DC 
Circuit Court of Appeals decision that had upheld the MATS rule. 
Mich. v. EPA, No. 14-46 (S. Ct. filed June 29, 2015). The Court did 
not vacate the rule, however, and it remains in effect.
---------------------------------------------------------------------------

I. Administrative Appeals Process

    Under either a rate-based or mass-based trading program, the EPA 
anticipates that there may be situations in which individual parties 
are affected by decisions of the agency. For example, under a rate-
based plan, a determination may be made that an eligibility application 
by an ERC provider is denied. And, for set-asides in the mass-based 
program, an affected EGU may believe that its allowance allocation 
amount was miscalculated. Similar to prior trading programs, the agency 
believes it would be efficient and potentially avoid the need for 
recourse to litigation to provide an administrative appeals process. 
Therefore we are proposing, and requesting comment on, the use of the 
regulations for appeals procedures set forth in 40 CFR part 78, to 
provide for the adjudication of certain disputes that may arise during 
the course of implementation of a federal plan under CAA section 
111(d). We also propose to revise part 78 to accommodate such appeals. 
The part 78 procedures cover prior CAA emission trading programs and 
were specifically designed with these types of disputes in mind.
    The persons eligible to file such appeals would be designated 
representatives as defined in this proposed rule and other ``interested 
persons'' as defined in part 78. The filing of an appeal and the 
exhaustion of administrative remedies under part 78 would be a 
prerequisite to seeking judicial review. For purposes of judicial 
review, final agency action would occur only when an agency decision 
under the federal plan listed as appealable under part 78 has been 
issued, and the procedures of part 78 for appealing the decision are 
exhausted.
    The actions we propose to list as appealable under the part 78 
procedures are as follows:
    In the case of the rate-based federal plan: Decisions on an 
eligibility application for ERCs; decisions regarding the number of 
ERCs generated; decisions on the transfer of ERCs; decisions on the 
disallowance of ERCs for compliance; decisions that there has been an 
excess of emissions requiring a 2-for-1 ERC administrative compliance 
penalty; decisions regarding deduction or surrender of ERCs for 
compliance from affected EGUs' compliance accounts; decisions on the 
accreditation of independent verifiers; the use of error corrections 
regarding information submitted by ERC providers, affected EGUs, or 
other ERC account holders; and the finalization of compliance period 
emissions data, including retroactive adjustment based on audit or 
other investigation.
    In the case of a mass-based federal plan: Decisions on an 
eligibilty application for set-aside allowances; decisions regarding 
the allocation of allowances to affected EGUs; decisions regarding the 
allocation of allowances from set-asides; decisions on the transfer of 
allowances; decisions regarding the finalization of emissions data by 
affected EGUs during compliance periods; decisions making error 
corrections to information submitted by affected EGUs and other account 
holders; decisions that there has been excess emissions requiring a 2-
for-1 allowance administrative compliance penalty; and decisions 
regarding the deduction or surrender of allowances for compliance from 
affected EGUs' compliance accounts.
    We request comment on this list of actions for both types of 
approaches to the federal plan, and whether there are other decisions 
that may be made in the course of implementation of the federal plan 
that are party-specific that would be appropriate to list as appealable 
under part 78. We also request comment on whether it would be 
appropriate for the EPA to finalize an administrative appeals process 
that differs in any way from that offered under part 78, or in addition 
to that offered under part 78. If so, we request comment broadly on all 
aspects of the alternative or additional adminsitrative appeals 
process, including with respect to any structural, procedural, 
subtantive, and timing requirements it should include, who should have 
access to it and in what manner, and how it would differ from part 78. 
Finally, we request comment on whether, similar to other programs 
identified in 40 CFR 78.1(a)(1), the agency should make the procedures 
of part 78 available to any actions of the Administrator under the 
comparable state regulations approved as a part of a state plan under 
the EGs.

J. Consistency of Program Structure With Clean Air Act Authority

    The EPA is co-proposing two distinct forms of emissions trading as 
the mechanism for federal implementation of standards of performance 
that achieve the emission performance levels determined by application 
of the BSER in the Clean Power Plan EGs. Both proposals are ``emission 
standard'' approaches as defined in the EGs, and the EPA is not 
proposing an approach like the ``state measures'' approach that is also 
available to states in the final EGs. The EPA has legal authority to 
establish either of the proposed trading systems as a federal plan 
under CAA section 111(d)(2). We discuss this topic briefly here and 
invite public comment. The EGs discussed the role of emissions trading 
in the BSER, see, e.g., section V.A of the preamble to the final EGs. 
The EPA regards this to be a separate issue and is not revisiting or 
reopening the discussion of the BSER or the role of trading in the BSER 
here. The EGs recognize and provide ample opportunity for states to 
establish standards of performance that allow the use of emissions 
trading or other multi-unit compliance approaches. Here we discuss why 
an emissions trading program is a lawful and appropriate form of 
federal ``implementation'' of a ``standard of performance'' under CAA 
section 111(d)(2). We invite comment on this legal discussion and the 
agency's interpretation of its authority.
1. General Section 111(d)(2) Authority
    Section 111(d)(2) provides that ``[t]he Administrator shall have 
the same authority [ ] to prescribe a plan for a State in cases where 
the State fails to submit a satisfactory plan as he would have under 
section 7410(c) of this title in the case of failure to submit an 
implementation plan . . .'' 42 U.S.C. 7411(d)(2)(A).\43\
---------------------------------------------------------------------------

    \43\ Section 111(d)(2) further provides that ``[i]n promulgating 
a standard of performance under a plan prescribed under this 
paragraph, the Administrator shall take into consideration, among 
other factors, the remaining useful lives of the sources in the 
category of sources to which such standard applies.'' The agency's 
interpretation of the ``remaining useful lives'' provision is 
discussed above in section III.G of this preamble.
---------------------------------------------------------------------------

    The phrase ``same authority to prescribe'' indicates that Congress 
viewed the EPA's authority to issue a federal plan for designated 
pollutants under CAA section 111(d) as, in some sense, co-extensive 
with its authority to issue a FIP for National Ambient Air Quality 
Standards (NAAQS) pollutants under CAA section 110. This authority 
under CAA section 111, of course, must be understood in reference to 
the purpose of that section (i.e., to achieve emission reductions for 
designated pollutants from designated facilities), rather than in 
reference to the purpose of CAA section 110 (i.e., to attain and

[[Page 64987]]

maintain the NAAQS). However, it has been the agency's longstanding 
view that, in both procedural and substantive respects, Congress 
intended that the CAA section 110 authority be looked to under CAA 
section 111(d)(2). See 40 FR 53340, at 53342 (November 17, 1975) (``It 
is obvious that [the Administrator] could only prescribe standards on 
some substantive basis. The references to section 110 of the CAA 
suggest that (as in CAA section 110) [she] was intended to do generally 
what the states in such cases should have done, which in turn suggests 
that (as in CAA section 110) Congress intended the states to prescribe 
standards on some substantive basis. Thus, it seems clear that some 
substantive criterion was intended to govern not only the 
Administrator's promulgation of standards but also [her] review of 
state plans.'').
    Over the several decades of implementation of the CAA, the courts, 
and the EPA, have addressed the nature and scope of CAA section 110 
authority. See, e.g., 71 FR 25328, 25338 (May 12, 2005) (CAIR final 
rule). In general, the EPA has broad power under CAA section 110(c) to 
cure a defective SIP. Thus, in promulgating a FIP under CAA section 
110, the EPA may exercise its own, independent regulatory authority in 
accordance with CAA section 110(c) and the CAA more broadly. When the 
EPA has promulgated a FIP, courts have not required explicit authority 
for specific measures: ``We are inclined to construe Congress' broad 
grant of power to the EPA as including all enforcement devices 
reasonably necessary to the achievement and maintenance of the goals 
established by the legislation.'' South Terminal Corp. v. EPA, 504 F.2d 
646, 669 (1st Cir. 1974). Further, the same authority that is exercised 
by the states under the CAA in connection with the adoption, 
implementation, and enforcement of a SIP may be assumed to be available 
to the EPA when the agency issues a FIP, after determining that a state 
has not adopted a satisfactory SIP. As the Ninth Circuit has held, when 
the EPA acts in place of the state pursuant to a FIP under CAA section 
110(c), the EPA ``stands in the shoes of the defaulting state, and all 
of the rights and duties that would otherwise fall to the state accrue 
instead to EPA.'' Central Ariz. Water Conservation Dist. v. EPA, 990 
F.2d 1531, 1541 (9th Cir. 1993). Accord, South Terminal, 504 F.2d at 
668 (``[T]he Administrator must promulgate promptly regulations setting 
forth an implementation plan for a state should the state itself fail 
to propose a satisfactory one. The statutory scheme would be unworkable 
were it read as giving to the EPA when promulgating an implementation 
plan for a state, less than those necessary measures allowed by 
Congress to a state to accomplish federal clean air goals. We do not 
adopt any such crippling interpretation.'').
    By the same token, if there are clear limits to the EPA's CAA 
section 110(c) authority, those too, would arguably carry over to CAA 
section 111(d)(2). For instance, CAA section 110(c)(1) ties the EPA's 
authority to promulgate a final FIP for a state to the EPA's predicate 
action on a SIP (or lack thereof): Generally, either an action 
disapproving a plan, or a finding that a state has failed to submit a 
plan. However, even here, as the Supreme Court has recognized, ``the 
plain text of the CAA grants EPA plenary authority to issue a FIP `at 
any time' within the 2-year period that begins the moment EPA 
determines a SIP to be inadequate.'' EPA v. EME Homer City Generation, 
134 S. Ct. 1584, 1602 n.14 (2014).
    Congress gave the EPA the same authority to prescribe a plan under 
CAA section 111(d)(2) as it possesses under CAA section 110(c). The EPA 
believes this authority is the ``same'' in the sense described above 
and in the case law.\44\ The scope of the EPA's action to undertake a 
FIP under CAA section 110 is informed by the scope of the state's 
action to undertake a SIP; likewise, the scope of the EPA's action to 
undertake a federal plan under CAA section 111(d) is informed by the 
scope of the state's action to undertake a state plan.
---------------------------------------------------------------------------

    \44\ We interpret the cross-reference to be to the currently 
enacted version of CAA section 110(c), rather than to a prior 
version. As discussed in section VII of this preamble, below, the 
current version of CAA section 110, including subsection (c), 
reflects changes made in the 1990 Amendments based on experience 
gained in the first two decades of the CAA's implementation. The 
statute and legislative history do not expressly address the 
question, but there is no indication Congress would have intended to 
prevent these improvements from being available under CAA section 
111 as well.
---------------------------------------------------------------------------

    The agency received comments on the proposed EGs from commenters 
who stated that the EPA cannot require states to implement the building 
blocks that make up the BSER; for example, ordering re-dispatch to 
natural gas-fired units, or ordering the construction of RE projects. 
These commenters went on to say that the EPA itself would have no 
authority to order these types of actions under a federal plan. As we 
explained in the Legal Memorandum for the final EGs, and reiterate 
here, the premise of these comments is incorrect. The EPA is not 
requiring the implementation of the BSER or the building blocks in the 
EGs. Even where the EPA is directly implementing standards of 
performance in a federal plan, the agency will not, and need not, 
attempt to order sources to implement the measures that comprise the 
BSER. Rather, as set forth in the co-proposed federal plans discussed 
in sections IV and V of this preamble, the EPA would set emission 
standards for each of the affected EGUs in the federal plan state, 
provide mechanisms for their implementation and enforcement, and 
otherwise leave to the owners and operators of the affected EGUs the 
decisions about what measures they want to take to comply with the 
emission standard. Though the emission standards will be federally 
enforceable, as under a state plan, sources may achieve them through 
implementation of measures in the BSER, or any other method.
    Thus, the question whether the EPA would have the authority to 
directly order the implementation of the measures in the building 
blocks in this proposed federal plan is not only not relevant but 
represents a categorical misunderstanding of the nature of the BSER in 
relation to the imposition of standards of performance under a CAA 
section 111(d) plan. To illustrate this, by the same token the EPA 
could not enforce many logistical aspects of a control requirement such 
as a scrubber--for instance, the EPA does not need to assert the 
authority to order into existence companies that manufacture scrubbers, 
or order their construction or delivery on a certain schedule. The EPA 
need not in setting emission standards have before it all of the 
information regarding manufacturing, transportation of parts, or other 
logistical requirements to ensure that each scrubber gets constructed 
and delivered to a source. Similarly, the EPA here does not, and need 
not, propose an implementation approach of directly intervening to re-
dispatch certain units, construct new RE projects, or take other 
measures, either included in the BSER or not. The agency determined the 
BSER and emission performance levels in the EGs on a reasonable 
assumption that all of those things can actually happen. In providing 
for the implementation of federally enforceable standards of 
performance in the federal plan proposed in this action, the agency is 
ensuring that these things will happen.
2. Use of Market Techniques To Implement Standards of Performance Under 
the Clean Air Act
    The use of market techniques such as emission trading is well-
supported in the CAA and has many regulatory precedents. The EPA 
discussed this history, and the reason why trading is a supportable 
method of

[[Page 64988]]

implementation of standards of performance under CAA section 111(d) in 
the EGs. See section V.A of the final EGs. Here we supplement that 
discussion with respect to the agency's own authority under CAA section 
111(d)(2) to use trading as a method of implementation of a ``standard 
of performance'' in the federal plan.
    The 1990 CAA Amendments added broad authorizations for the use of 
market techniques in several sections of the statute, including Title 
I. States were provided express authority to use such approaches in 
their NAAQS implementation plans under CAA section 110(a)(2)(A): ``Each 
[state] plan shall include enforceable emission limitations and other 
control measures, means, or techniques (including economic incentives 
such as fees, marketable permits, and auctions of emissions rights) . . 
. .'' 42 U.S.C. 7410(a)(2)(A). The EPA was given similar authority in 
the definition of a ``Federal Implementation Plan'' in CAA section 302, 
which defines that term as an EPA-promulgated plan, which ``includes 
enforceable emissions limitations or other control measures, means or 
techniques (including economic incentives, such as marketable permits 
or auctions of emissions allowances), and provides for attainment of 
the relevant national ambient air quality standard.'' 42 U.S.C. 
7602(y). Section 111(d)(2) of the CAA provides the EPA the same 
authority to prescribe a federal plan under CAA section 111 as it would 
have to promulgate a FIP under CAA section 110(c). Thus, the EPA 
believes the plain language of the statute authorizes the use of market 
techniques in CAA section 111(d) federal plans.
    However, even if one were to view this language as not wholly 
unambiguous with respect to the scope of federal authority under CAA 
section 111, the EPA believes that CAA section 111, in conjunction with 
authorizations and endorsements of market techniques throughout the 
CAA, and other indicia of congressional intent, strongly support the 
view that market techniques are within the EPA's authority to 
promulgate a federal plan under CAA section 111(d).
    Case law throughout the history of the CAA has generally confirmed 
the legal viability of emissions trading as an implementation measure 
so long as the trading ultimately achieves the emission reduction goals 
of the statute. See, e.g., Sierra Club v. EPA, No. 12-3169 (6th Cir. 
Filed March 18, 2015), Slip Op. at 11-14 (upholding EPA approval of 
redesignation of area to attainment on basis that reductions in 
emissions from cap-and-trade programs (NOX SIP Call, CAIR, 
and CSAPR) are permanent and enforceable). Chevron, U.S.A., Inc. v. 
Natural Res. Def. Council, Inc., 467 U.S. 837 (1984) (``Chevron''), the 
seminal case establishing the Supreme Court's standard of review of 
agency interpretations of the statutes they administer, upheld one of 
the EPA's early emissions trading programs, the Netting Rules of 1980 
(45 FR 52676; August 7, 1980), which the EPA in its discretion chose to 
allow states to apply in both attainment and nonattainment areas (46 FR 
50766; October 14, 1981). The Netting Rules allowed existing major 
sources to modify without triggering certain requirements of PSD or 
nonattainment NSR, so long as any increase in emissions associated with 
the modification is compensated for by a corresponding decrease in 
emissions elsewhere within the same facility, such that there is no 
significant net increase in emissions from the facility as a whole. In 
upholding this approach in Chevron, the Supreme Court gave deference to 
the EPA's definition of the term ``source,'' finding in that term 
sufficient ambiguity to support the agency's reasoned application of an 
emissions averaging approach for total pollution emitted from the 
source. See EPA v. EME Homer City, 134 S. Ct. 1584, 1603 (2014) 
(``Because `a full understanding of the force of the statutory policy . 
. . depend[s] upon more than ordinary knowledge' of the situation, the 
administering agency's construction is to be accorded `controlling 
weight unless . . . arbitrary, capricious, or manifestly contrary to 
the statute.' '') (quoting Chevron, 467 U.S. at 844).\45\
---------------------------------------------------------------------------

    \45\ The EPA is not aware of any case since at least the Chevron 
decision in which a trading program under the CAA was invalidated 
simply by virtue of being a trading program. The CAIR trading 
program was set aside by the DC Circuit because the court held it 
did not accomplish the objective of the Good Neighbor provision of 
the CAA, not because it used a trading approach per se. North 
Carolina v. U.S. EPA, 531 F.3d 896, 921 (D.C. Cir. 2008). More 
recently the Supreme Court upheld key portions of the CSAPR trading 
program that replaced CAIR in EPA v. EME Homer City, 134 S. Ct. 1584 
(2014).
---------------------------------------------------------------------------

    With the increasing recognition of the utility of trading, 
crediting, and averaging to meet emission reduction goals efficiently, 
the EPA set forth a comprehensive policy on trading in 1986. Emissions 
Trading Policy Statement; General Principles for Creation, Banking and 
Use of Emission Reduction Credits, 51 FR 43814 (December 4, 1986) 
(hereinafter ``ERC Policy''). In the ERC Policy, the EPA stated that it 
``endorses emissions trading and encourages its sound use by states and 
industry to help meet the goals of the CAA more quickly and 
inexpensively.'' At the same time, based on lessons learned from its 
earlier 1982 trading policy, the EPA took steps to tighten its policies 
on the use of ``bubbles'' to ensure environmental integrity of trading, 
particularly in nonattainment areas. The agency emphasized the 
requirements of enforceability, tracking (and preventing double-
counting), determining the appropriate baseline from which to measure 
emissions, and demonstration of actual air quality benefits.
    The use of an emissions trading system for CO2 
reductions for affected EGUs under CAA section 111(d) is also analogous 
to the trading system for chlorofluorocarbons (CFCs) under the pre-1990 
CAA provision for control of stratospheric ozone depleting substances. 
This program was reviewed by the Office of Legal Counsel (OLC) within 
the Department of Justice in 1989. See Memorandum for Alan Raul, 
General Counsel, Office of Management and Budget, from the Office of 
the Assistant Attorney General (April 14, 1989) (hereinafter ``OLC 
Memo'').\46\ The OLC was asked by OMB to opine whether a general grant 
of regulatory authority to the EPA to ``control'' CFCs was sufficient 
to authorize an emissions fee or a cap-and-trade system, including 
auction, of tradable allowances. The statute authorized the EPA to 
issue regulations ``for the control of any substance, practice, 
process, or activity (or any combination thereof) which in his judgment 
may reasonably be anticipated to affect the stratosphere, especially 
ozone in the stratosphere, if such effect in the stratosphere may 
reasonably be anticipated to endanger public health.'' Former CAA 
157(b) (as enacted in the 1977 CAA amendments). The Office of Legal 
Counsel concluded that this language--which it characterized as 
``plain,'' ``unambiguous,'' and ``sweeping''--was sufficient to 
authorize the EPA to establish a cap-and-trade program with auction for 
CFCs. See id. at 7 (``It cannot seriously be argued that the use of 
economic incentives to regulate pollution is a novel or strange idea 
that could not have been anticipated by the authors of the Clean Air 
Act Amendments [of 1977].'') (citing multiple examples from the policy 
literature as early as E. Mishan, The Costs of Economic Growth (1967)). 
The OLC noted that as of 1977, ``Congress was cognizant of economic 
forms of regulation, did not prohibit them, but instead used general 
language

[[Page 64989]]

permitting a wide scope of regulatory measures for the control of 
CFCs.'' To interpret the general authority of this section of the CAA 
as affirmatively prohibiting market incentives would be, in the OLC's 
words, to read into the statute the italicized clause ``regulations for 
the control [of CFCs] by traditional command and control or 
specification standard methods,'' id. at 9--a rewriting ``unwarranted 
in any case, but especially so where Congress was aware of economic 
methods of control and where such methods so ably serve the underlying

    By the time of the 1990 CAA Amendments, as discussed above, 
Congress was comfortable enough with the efficacy of market techniques 
that they were broadly authorized for use in SIPs and FIPs for NAAQS. 
See 42 U.S.C. 7410(a)(2)(A), 7602(y). In the wake of the 1990 
Amendments, the EPA issued an ``Implementation Strategy for the Clean 
Air Act Amendments of 1990.'' \47\ This Strategy included as one of 
nine overarching implementation principles, ``Market-based: Use of 
market-based approaches and other innovative strategies to creatively 
solve environmental problems.'' Further, it announced that the EPA 
would make ``full use of innovative market-based approaches,'' and that 
the agency will supplement traditional approaches with broader use of 
market incentives and other innovative approaches ``whenever 
possible.'' Id. at 3, 9.

---------------------------------------------------------------------------

    Since the 1990 Amendments, the EPA has established three of its 
most robust trading programs--the Federal NOX Budget Trading 
Program (65 FR 2674; January 18, 2000), the CAIR (71 FR 25328; April 
28, 2006), and the CSAPR (76 FR 48208; August 8, 2011), under CAA 
section 110(a)(2)(D)(i)(I), relating to air pollution that causes 
nonattainment or interference with maintenance of air quality standards 
in downwind states.\48\
---------------------------------------------------------------------------

    \48\ The EPA notes that complications that arise with respect to 
assigning a ``significant contribution'' among upwind states for 
NAAQS pollutant levels in downwind states, and designing a trading 
regime that accomplishes Good Neighbor objectives, are not present 
with respect to CO2, which is a global pollutant; 
emission reductions anywhere contribute to the environmental 
objective of addressing climate change.
---------------------------------------------------------------------------

    As noted in the rulemaking action for the final EGs, the EPA has 
instituted or authorized the use of emissions trading programs twice in 
the past under CAA section 111(d). The EPA authorized NOX 
emissions averaging or trading within or between facilities under the 
Municipal Waste Combustors EGs in 1995. 60 FR 65387, 65402 (December 
19, 1995) (codified at 40 CFR 60.33b(d)(1) and (2)). The EPA also 
developed a cap-and-trade system for mercury under CAA section 111(d) 
in the Clean Air Mercury Rule (CAMR). 70 FR 28606 (May 18, 2005). The 
EPA proposed a federal plan for trading that was identical in all 
relevant respects to the CAMR rule. 71 FR 77100 (December 22, 2006). 
However, CAMR was vacated by the D.C. Circuit on grounds unrelated to 
the establishment of a trading system for implementation before the 
CAMR federal plan could be finalized. New Jersey v. EPA, 517 F.3d 574 
(D.C. Cir. 2008).\49\
---------------------------------------------------------------------------

    \49\ The CAMR program was vacated because the EPA had not made 
requisite findings under CAA section 112(c)(9) in delisting EGUs 
with respect to emissions of a hazardous air pollutants (HAP). No 
such procedural concern is present here with respect to 
CO2, which is not a HAP under CAA section 112.
---------------------------------------------------------------------------

    The agency believes these legal and administrative precedents for 
federal trading programs under the CAA going back decades amply support 
its decision to propose two forms of emission trading as the method of 
implementation of the Clean Power Plan EGs in the federal plan. 
Notably, emissions trading is particularly appropriate with respect to 
a global pollutant such as CO2 that is well-mixed in the 
atmosphere and does not have direct, acute health impacts due to 
inhalation at ambient levels.\50\
---------------------------------------------------------------------------

    \50\ We recognize that some commenters on the EGs raised 
concerns about the localized impacts that may occur from the 
potential for concentrations of co-pollutants associated with 
CO2 emitted from affected EGUs. We address those concerns 
in the communities sections of the final EGs, at section IX, and in 
this preamble in section IX below.
---------------------------------------------------------------------------

    Finally, the Supreme Court has affirmed the breadth of the agency's 
discretion under CAA section 111(d) to select the method by which it 
would control CO2 emissions from existing power plants. See 
AEP v. Connecticut, 131 S. Ct. 2527, 2538 (2011) (``Congress delegated 
to EPA the decision whether and how to regulate carbon-dioxide 
emissions from power plants.'') (emphasis added); see also id. at 2539 
(``The appropriate amount of regulation in any particular GHG-producing 
sector cannot be prescribed in a vacuum: As with other questions of 
national or international policy, informed assessment of competing 
interests is required. Along with the environmental benefit potentially 
achievable, our Nation's energy needs and the possibility of economic 
disruption must weigh in the balance. The CAA entrusts such complex 
balancing to the EPA in the first instance, in combination with state 
regulators.'').
    This proposal is guided by the relevant cases and the experiences 
of the agency in implementing the CAA trading programs discussed above. 
The EPA invites comment on this discussion and the agency's 
interpretation that CAA section 111(d)(2) authorizes the two approaches 
to a federal plan proposed here.

IV. Rate-Based Implementation Approach

A. Overview

    The EPA's federal plan requirements for CO2 from 
affected EGUs implement the EGs as previously discussed. In this 
federal plan and model rule proposal the EPA is proposing, as one 
option, rate-based emission standards (i.e., the emission standard 
approach) for affected EGUs not covered by an approved state plan as 
specified in the Clean Power Plan. The EPA is proposing to apply the 
subcategorized emission rates in this federal plan proposal. These 
rate-based emission standards are consistent with, and would satisfy, 
the degree of emission limitation achieved by the BSER determination 
made in the final Clean Power Plan EGs, which included subcategorized 
CO2 emission performance rates for affected EGUs to meet 
during the plan performance periods. An affected EGU subject to this 
federal plan will demonstrate compliance by achieving a stack emission 
rate less than or equal to the rate-based emission standard or by 
applying ERCs, acquired by the EGU, to its measured stack emissions 
rate. The application of ERCs by an affected EGU to comply with an 
emission standard has been determined in the final Clean Power Plan as 
a mechanism available to affected EGUs with a CO2 emission 
rate greater than its respective performance rate to meet compliance 
obligations, see section VIII.K of the final EGs. Under a rate-based 
federal plan, the EPA would act as the state described in section 
VIII.C.1.a of the final EGs with the EPA acting as the issuer of ERCs, 
and otherwise implementing and enforcing the standards of performance 
for affected EGUs subject to the federal plan.
    This section describes the proposed rate-based federal plan and 
model trading rule and how each would be designed and operated, 
consistent with the EGs. For the federal plan, the EPA is proposing to 
limit the issuance of ERCs to designated categories of affected EGUs 
and to RE resources and nuclear generation (from new capacity and 
incremental capacity uprates) that are

[[Page 64990]]

measured by a revenue quality meter, rather than the full suite of 
options discussed in the EGs. The EPA requests comment on whether to 
limit the scope of the federal plan in this manner, and if not, what 
other sources of low- or zero-emitting electricity in federal plan 
states should also be eligible to generate ERCs for compliance 
purposes. For both the proposed federal plan and model rule, the EPA 
requests comment on which EM&V plan, measurement and verification (M&V) 
report, and verification report requirements should apply for each 
eligible resource. Further discussion of non-BSER measures that may be 
eligible to generate ERCs can be found in the Clean Power Plan and 
section IV.C.3 of this preamble. (The EPA is not reopening its 
determination of the BSER.)

B. Rate Goals

    In the Clean Power Plan the EPA identified a rate-based ``emission 
standards'' approach as an approvable method for state plans to 
implement the final EGs. In this approach the requirements for 
compliance rest solely on affected EGUs in the form of federally 
enforceable emission standards expressed as a rate of emissions of 
CO2 per unit of energy output. In the Clean Power Plan, the 
EPA established, through application of the BSER, separate 
CO2 emission performance rates for affected EGUs in two 
subcategories. The two subcategories are natural gas-fired stationary 
combustion turbines (i.e., natural gas combined cycle units, or NGCC 
units) and fossil fuel-fired EGUs (i.e., utility boilers and IGCC).\51\ 
The CO2 emission performance rates set in the Clean Power 
Plan are reflected below in Table 6 of this preamble. The EPA is 
proposing to apply these rates in the rate-based federal plan as the 
emission standards for NGCC units, and SGUs, respectively. For a 
thorough discussion of affected EGU category-specific CO2 
emission performance rates and rationale, see section VI of the final 
EGs. These calculated standards and the premises that these standards 
are based on are not within the scope of comment in this rulemaking as 
they were finalized in the Clean Power Plan.
---------------------------------------------------------------------------

    \51\ For simplicity, affected utility boilers and IGCC will 
collectively be called ``steam generating units.''
---------------------------------------------------------------------------

    As discussed in section III.D of this preamble above, the EPA 
proposes to implement a compliance schedule for the rate-based federal 
plan with multi-year compliance periods as follows: A 3-year period 
(2022 through 2024), followed by a 3-year period (2025 through 2027), 
followed by a 2-year period (2028 and 2029), for the Interim Period; 
and, commencing in 2030, successive 2-year compliance periods for the 
Final Period. In the Clean Power Plan, the EPA established 
CO2 emission performance rates for the subcategories of 
affected EGUs for the performance periods. The EPA proposes to use 
those emission performance rates promulgated in the Clean Power Plan as 
the rate-based emission standard for the respective EGUs that would 
become subject to this proposed federal plan if finalized. The EPA is 
not opening for comment the determinations made in the Clean Power Plan 
of each subcategorized CO2 emission performance rates. The 
rate-based emission standards for respective EGU types are provided for 
convenience in Table 6 of this preamble.
    The EPA is proposing to use a glide path during the Interim Period 
for EGUs to provide a smooth transition to the final compliance periods 
after 2030. This approach is established in the final EGs. In Table 6 
of this preamble, the applicable standards for each interim compliance 
period are listed.

 Table 6--Glide Path Interim Performance Rates (Adjusted Output-Weighted-Average Pounds of CO2 per Net MWh From
                                      All Affected Fossil Fuel-Fired EGUs)
----------------------------------------------------------------------------------------------------------------
                                                     2022-2024       2025-2027       2028-2029

                                                       rate            rate            rate
----------------------------------------------------------------------------------------------------------------
SGU or IGCC.....................................           1,671           1,500           1,380           1,305
Stationary combustion turbine...................             877             817             784             771
----------------------------------------------------------------------------------------------------------------

    The EPA is using the subcategorized rates in the rate-based trading 
approach because it allows ERCs to be fungible across jurisdictional 
borders and provides an incentive structure, as compared to other rate-
based approaches, that facilitates implementation of measures 
identified as part of the BSER. Using subcategorized rates allows for: 
(1) Consistently applied emission rates for power plants of different 
types; and (2) free trading of fungible ERCs among all affected EGUs 
subject to the federal plan and within the federal trading program. The 
EPA solicits comments on whether the subcategorized rate approach is 
the preferred rate-based approach for the federal plan and model 
trading rule.\52\ If a subcategorized approach for a rate-based model 
rule and federal plan is not preferred by commenters, the EPA requests 
comment on the perceived benefits of an alternative rate or set of 
rates (e.g., applying a uniform rate, i.e., the state goal, to all 
affected units within the state as the EGUs' emission standard).
---------------------------------------------------------------------------

    \52\ Note that the values of limits and determinations made as 
the BSER are not open for comment.
---------------------------------------------------------------------------

C. Crediting Mechanism

    Under a rate-based emission standard approach in the federal plan, 
we are proposing that EGUs subject to the emission performance 
requirements for GHGs will either need to emit at or below their rate-
based emission standard, or they will need to acquire ERCs to achieve 
compliance. An ERC is a tradable compliance unit representing one MWh 
of electric generation (or reduced electricity use) with zero 
associated CO2 emissions. These ERCs may then be used to 
adjust the measured and reported CO2 emission rate of an 
affected EGU when demonstrating compliance with a rate-based emission 
standard. For each ERC, one MWh is added to the denominator of the 
reported CO2 emission rate, resulting in a lower adjusted 
CO2 emission rate.
    Under this proposed federal plan, ERCs will be issued by the EPA to 
four categories of entities: (1) Affected EGUs that perform at a rate 
below the applicable rate-based emission standard; (2) affected NGCC 
units for all generation (represents shifting generation from SGUs to 
NGCC units, as anticipated under Building Block 2); (3) new nuclear 
units and capacity uprates at existing nuclear units; and (4) RE 
providers that develop metered projects and programs whose results, in 
MWh, are quantified and verified according to

[[Page 64991]]

EM&V criteria as described below in section IV.D.8 of this preamble. We 
are also discussing in this preamble, requesting comment for the 
federal plan, and proposing for the model trading rule a potential 
fifth category: Other low- and zero-emitting non-BSER measures that are 
described in section IV.C.3 of this preamble. The concept of using an 
ERC as a crediting mechanism to meet compliance obligations is 
consistent with the Clean Power Plan EGs and is being adopted in this 
federal plan.\53\
---------------------------------------------------------------------------

    \53\ The use of ERCs and definition as a compliance mechanism to 
meet the BSER emission performance rates is established in section 
VIII.K of the final EGs.
---------------------------------------------------------------------------

    Because the goal of this rulemaking is the actual reduction of 
CO2 emissions, it is fundamental that ERCs represent the MWh 
of energy generation or savings they purport to represent. To this end, 
only valid ERCs that actually meet the standards articulated in this 
rule may be used to satisfy any aspect of compliance by an affected EGU 
with emission standards. The responsibility for the validity of the ERC 
rests with the affected EGU. Despite safeguards included in the 
structure of ERC issuance and tracking systems, such as the review of 
eligibility applications and M&V reports, and EPA issuance of ERCs, 
ERCs may be issued that do not, in fact, represent eligible zero-
emission MWh as required in the EGs. A variety of situations may result 
in such improper ERC issuance, ranging from simple paperwork errors to 
outright fraud. The EPA requests comment on ways that the EPA could 
safeguard the validity of an ERC.
1. ERCs Generated and Owed Against a Standard
    The number of ERCs generated or needed for surrender by an affected 
fossil fuel-fired EGU is based on the CO2 emission rate of 
the EGU in comparison to a rate-based emission standard. The 
calculation of ERCs generated by an EGU or needed for compliance is the 
CO2 stack emission rate of the EGU subtracted from the 
standard the EGU is subject to, and this value is subsequently divided 
by the standard the EGU is subject to. This value is a normalized 
quantity of how much better or worse the EGU is performing compared to 
its standard. The normalized value is weighted by multiplying the MWh 
electricity output from the EGU at that emission rate. This can be 
generically expressed as:
[GRAPHIC] [TIFF OMITTED] TP23OC15.008

    If the value calculated is positive, this indicates the number of 
ERCs that are being generated; conversely, a negative value indicates 
how many ERCs will need to be acquired to meet the unit's emission rate 
for that compliance period. ERCs will be issued on an annual basis to 
ERC providers (i.e., entities generating ERCs via the ERC approval and 
issuance process detailed below). Surrender of ERCs for compliance by 
affected EGUs will not occur until the end of the compliance period as 
further described in section IV.D.10 of this preamble.
    As an example, assume a steam EGU operating in the second interim 
compliance period is subject to a rate standard of 1,500 lbs 
CO2/MWh. Assume it operates at 2,000 lbs CO2/MWh, 
and also assume it generates 1 million MWh over a compliance period. 
Its total emission rate would be 2 billion lbs CO2/1 million 
MWh. In order to achieve the emission standard, it would need to 
purchase 333,334 ERCs (rounded to the nearest higher integer). In 
essence, this quantity of ERCs represents the quantity of MWh that need 
to be added to the steam EGU's denominator (i.e., generation, here, 1 
million MWh), such that 2 billion pounds of CO2 (total 
emissions), divided by total generation (i.e., in this case, 1,333,334 
MWh) equals the emission rate for compliance (1,500 lbs/MWh).
    The discussion in this subsection builds on and applies the 
definition, benefits, use, and determination of using ERCs from the 
final EGs (section VIII of the final EGs). We invite comment on use of 
the approach just described as a method of implementation of a federal 
plan and a model trading rule, and we request comment on any 
alternatives to this approach that still fall within the established 
criteria described in the Clean Power Plan EGs. Comments that solely 
relate to determinations finalized in the EGs will be considered 
outside the scope of this proposed rule.
2. Incremental NGCC ERCs
    Building Block 2 (BB2) of the BSER determination in the Clean Power 
Plan EGs describes shifting generation from SGUs to NGCC units because 
NGCC units generate electricity at a less carbon intensive rate. BB2 
describes NGCC units generating at 75 percent of the unit's annual 
operating capacity. This level of generation, for most NGCC units, 
would represent an increase in annual generation from a 2012 baseline. 
For every hour of electricity generated by an NGCC unit beyond its 2012 
baseline (i.e., incremental generation), there is a corresponding 
emission reduction in the power system.\54\ The EPA is proposing to 
reflect the emission reductions of BB2 by crediting all NGCC generation 
on a pro rata basis that reflects expected incremental NGCC generation 
to 75 percent capacity. This means that for every hour that an NGCC 
unit generates electricity, it will also generate a partial credit 
associated with the generation shift from fossil steam to NGCC units. 
The NGCC unit will generate a partial credit because the emission 
reductions associated with BB2 have been distributed on an hourly 
basis. A discussion on the concepts behind the distribution of emission 
reductions of incremental NGCC generation on an hourly basis can be 
found at the end of this subsection.
---------------------------------------------------------------------------

    \54\ It is assumed that any increase in NGCC generation above 
2012 levels is displacing fossil fuel-fired steam EGU generation.
---------------------------------------------------------------------------

    All affected NGCC generation will be credited, with ERCs, by a 
factor that represents the described emission reductions from 
incremental generation; ERCs credited in this way will be designated as 
Gas Shift ERCs (GS-ERCs) for clarity.\55\ The collective sum of the GS-
ERCs generated realizes the amount of emission reductions described in 
BB2 when 75 percent capacity is achieved. This incentive is not a 
requirement, however. If NGCC units do not collectively increase to 75 
percent capacity or above, the lost opportunity for ERC generation 
simply will need to be achieved through other means (e.g., emissions 
performance improvements at

[[Page 64992]]

affected EGUs or additional RE generation). The amount of GS-ERCs the 
EPA proposes to be generated for every MWh of NGCC operation is set at 
a factor relating the amount of electricity generation that NGCC units 
collectively would generate at the level described in BB2 (i.e., 
reaching 75 percent capacity) and the associated emission reductions. 
This means that fractional GS-ERCs are generated for every NGCC MWh and 
when the interconnect region collectively reaches the level that would 
be generated if all NGGC units in the region operated at a 75 percent 
capacity factor there will be an amount of GS-ERCs that correlates to 
the emission reductions anticipated under BB2 of the BSER. NGCC units 
are expected to be incentivized to reach this level of generation in 
part due to market demand for GS-ERCs. Thus, GS-ERCs have the potential 
to play an important role in the sector meeting compliance obligations.
---------------------------------------------------------------------------

    \55\ A GS-ERC is treated and represents the same value as an 
ERC, but has a compliance restriction that it can only be used by 
steam generating units and not by stationary combustion turbines for 
compliance obligations.
---------------------------------------------------------------------------

    The number of GS-ERCs that an NGCC unit generates is a combination 
of three factors. The first is the GS-ERC Emission Factor. This 
emission factor represents how much better an individual NGCC's 
emission rate is compared against the fossil steam standard. This 
measures the emission reductions because of the BB2 shift in 
generation. The SGU standard used as reference here is as described 
above in section IV.B of this preamble and established in the BSER 
determination from the EGs of the least stringent region \56\ (i.e., 
the region with the highest calculated rate-based emission standard for 
SGUs). The GS-ERC Emission Factor is expressed by taking the complement 
of the ratio of the NGCC standard to the fossil-steam standard. It can 
be summarized by the following expression:
---------------------------------------------------------------------------

    \56\ The regions that are used in the Clean Power Plan EGs and 
for this proposal are the Eastern Interconnect, Western 
Interconnect, and Electric Reliability Council of Texas (ERCOT).
[GRAPHIC] [TIFF OMITTED] TP23OC15.009

    The second factor is the Incremental Generation Factor. This factor 
represents the distribution of the increased NGCC generation across all 
NGCC generation. In essence, it is prorating the incremental NGCC 
generation over all NGCC generation. The Incremental Generation Factor 
is calculated by taking the number of MWh beyond the 2012 baseline 
needed for the corresponding region to reach 75 percent NGCC generation 
capacity and dividing it by the MWh that is 75 percent NGCC generation 
capacity, giving a factor. This factor can be summarized by the 
following expression:
[GRAPHIC] [TIFF OMITTED] TP23OC15.010

    The Incremental Generation Factor is a factor that the EPA will 
calculate and will be calculated for every compliance period based on 
the least stingent region's Incremental Generation Factor based on 
increased utilization of RE and its replacement of fossil fuel-fired 
generation (based on Building Block 3 of the Clean Power Plan EGs).\57\ 
For the calculation of this factor the EPA is using the least stringent 
region for each compliance period and applying it for all GS-ERC 
calculations subject to the federal plan. The calculations for 
determinating the least stringent regional Incremental Generation 
Factor can be found in the GS-ERC TSD. Table 7 of this preamble 
presents the proposed values that would apply for all NGCC units to 
calculate the amount of issued GS-ERCs.
---------------------------------------------------------------------------

    \57\ Note that per the discussion in section VI of the final 
EGs, if the EPA had measured incremental NGCC generation for 
reassignment to fossil steam rate as the difference from the post 
building block three levels and full utilization, the post building 
block three levels would be used in the numerator here, resulting in 
a higher ``incremental generation factor'' and more ERCs for the 
same amount of NGCC generation.

----------------------------------------------------------------------------------------------------------------

    The third factor in calculating an NGCC unit's generaton of GS-ERC 
is the NGCC Generation. The NGCC Generation is the total net energy 
output generation of the affected NGCC unit during the year that ERCs 
are being calculated. The three factors combine to make the following 
equation:

GS-ERCs = NGCC Generation * Incremental Generation Factor * GS-ERC 
Emission Factor

    The GS-ERC equation above gives the number of GS-ERCs that an NGCC 
unit will generate. The Incremental Generation Factor and GS-ERC 
Emission Factor combine to make the GS-ERC generating rate for the NGCC 
unit. This functions by the Incremental Generation Factor prorating all 
incremental NGCC generation and the GS-ERC Emission Factor designating 
the proportion of the incremental NGCC generation that will generate 
ERCs. The GS-ERC generating rate multiplied by the total NGCC 
Generation gives the total GS-ERCs generated by the NGCC unit for the 
year.
    The EPA is proposing this approach, which provides GS-ERCs for all 
affected EGU NGCC generation but at a fractional, pro rated level, 
using the three factors above, for several reasons. This approach has 
the benefit of

[[Page 64993]]

allowing NGCC units to bid into the electricity market without having 
to adjust bids based on a projection of whether or not the NGCC unit 
will have generation incremental to its baseline in a given year. The 
proposed method also promotes the best performers within the NGCC 
subcategory by crediting them with a higher rate of generating GS-ERCs, 
as shown by the calculations above. The better the emission performance 
of an NGCC unit, the more GS-ERCs it is capable of earning per MWh. The 
proposed method also promotes and incentivizes all NGCC units, 
regardless of historical generation, to continue to operate at a 
greater capacity to replace steam generation. The EPA believes that 
this will allow for more fluidity in the market and flexibility for 
greater NGCC generation.
    In the Clean Power Plan the BSER determination for subcategory 
rates is calculated by using the least stringent region and applying 
the standards from that region on a national level. The determination 
of the BSER in the final EGs was a one-time determination and is not 
being altered, updated, or changed here. Rather, in this preamble the 
EPA is proposing to use the same regions and to apply the least 
stringent components to an NGCC unit's GS-ERC calculation at a national 
level (i.e., applying the GS-ERC calculation components that generate 
the most GS-ERCs for every MWh). The EPA solicits comment on applying 
the least stringent regional factor to calculate GS-ERCs for all 
affected NGCC units subject to the federal plan and model rule on a 
national level. Conversely, the EPA also requests comment on applying, 
for each region, its own regional GS-ERC generation rate. As proposed, 
the least stringent region could change from compliance period to 
compliance period. The EPA requests comment on whether a single ``least 
stringent'' region should be chosen and used for calculations or 
whether being ``least stringent'' should be evaluated on a compliance 
period by compliance period basis. The EPA also requests comment on 
whether ``least stringent'' should be evaluated on a year-to-year 
basis.
    The EPA also requests comment on whether the GS-ERC Emission Factor 
should be calculated on a unit by unit basis (as currently proposed) or 
be calculated based on the least stringent region's baseline 2012 
average emission rate. This will simplify the practice of calculating 
and distributing GS-ERC generation, but would not reward the better 
performing NGCC units within the subcategory. In the GS-ERC TSD, the 
EPA used the regions' average emission rate to calculate a factor that 
would credit GS-ERCs to all NGCC units subject to the federal plan. For 
2030 and beyond, this value is based on the Eastern Interconnect and is 
0.08 GS-ERCs/MWh. So for every MWh that an NGCC unit generates it would 
be issued 0.08 GS-ERCs and, if this were the approach the EPA proposed, 
this would apply to every NGCC unit that would be subject to the 
federal plan.
    In the GS-ERC TSD, the spreadsheet can be manipulated to show what 
an individual NGCC unit's GS-ERC Emission Factor would be in the 
proposed method. This is done by adjusting the cell for a year's 
Average GS-ERC Emission Factor to account for the individual NGCC 
unit's emission rate instead of the average NGCC emission rate.
    The calculation of GS-ERCs for an NGCC unit is independent of the 
calculation of ERCs generated or owed against the NGCC standard. It is 
possible that an NGCC unit will owe ERCs against its assigned emission 
standard for every MWh generated, but still be generating GS-ERCs. GS-
ERCs may only be used to meet steam generation units' compliance 
obligations.
    As an example, an NGCC unit is connected to the grid and generates 
1 million MWh of electric output for the first year of the final 
performance period. During this year it emits 850 million lbs of 
CO2 giving it an emission rate of 850 lbs CO2/
MWh. The NGCC unit is subject to a Final Period emission rate limit of 
771 lbs CO2/MWh. Since the NGCC unit is always subject to 
its NGCC rate-based emission standard of 771 lbs/MWh and it is 
operating at a rate above that standard it will owe non GS-ERCs for its 
own compliance. The ERCs owed are calculated by solving for the number 
of ERC MWh the NGCC unit will need to adjust its rate down to its 
emission rate limit. This is shown in the following equation:

850,000,000 lbs CO2/[1,000,000 MWh + ERC MWh] = 771 lbs 
CO2/MWh

    When that equation is solved for the number of ERC MWh needed, the 
NGCC unit would need to acquire 102,464 ERCs to adjust its emission 
rate to its rate-based emission standard.
    Additionally, the GS-ERC Emission Factor for this NGCC unit is 
calculated by using 771 lbs CO2/MWh for the NGCC emission 
rate and 1,404 lbs CO2/MWh for the SGU emission standard in 
the equation described above.
[GRAPHIC] [TIFF OMITTED] TP23OC15.011

    This calculation results in a GS-ERC Emission Factor of 0.45. This 
is only an example. Because the Incremental Generation Factor is 
calculated by the EPA, it can be found in the GS-ERC TSD and is 
proposed to be 0.26. By using the GS-ERC Emission Factor and 
Incremental Generation Factor calculated above with the NGCC unit's 
generation for the year, the number of GS-ERCs for this NGCC unit can 
be calculated.

0.45 * 0.26 * 1,000,000 = GS-ERC

    The calculation results in 117 thousand GS-ERCs being generated. 
Because an NGCC unit cannot use the GS-ERCs it generates to meet its 
compliance obligations, this NGCC unit will both generate ERCs (117,000 
GS-ERCs) and owe ERCs (102,464 non-GS-ERCs against NGCC standard). This 
NGCC unit may sell (or otherwise transfer) or bank its GS-ERCs. If a 
GS-ERC is sold, those proceeds may, in turn, be used to acquire non-GS-
ERCs to satisfy the NGCC unit's compliance obligations.
    A GS-ERC may not be used to meet an NGCC unit's compliance 
obligation because they are generated to reflect incremental NGCC 
generation replacing a SGU's generation. The calculation to derive a 
GS-ERC represents this generation shift. If a GS-ERC were to be used 
for compliance for an NGCC unit it would represent a shift from one 
NGCC unit to another, which serves little purpose in achieving emission 
reductions.
    The EPA requests comment on the proposed approach and requests 
comment and suggestions on other approaches for existing NGCC units to 
generate GS-ERCs at all times. The EPA is considering this methodology 
that GS-ERCs are generated for all NGCC generation because it ensures 
that all existing NGCC units are encouraged to run at a greater 
capacity. The EPA requests comment on alternative methods to account 
for NGCC units

[[Page 64994]]

generating GS-ERCs. Specifically, the EPA solicits comment on NGCC 
units generating GS-ERCs once a threshold of electric generation for 
the year is exceeded. This threshold is based on 2012 as a baseline and 
any NGCC generation beyond this threshold would be considered 
incremental generation. There are two different options to evaluate 
against a baseline. The first is on a unit-level, if an NGCC unit 
generates more than it did in 2012, all generation above the 2012 level 
(i.e., incremental generation) is eligible to be credited with GS-ERCs. 
The other threshold option is to use a percentage threshold. Evaluated 
on a regional level, the 2012 baseline capacity percentage for NGCC 
units in the least stringent region is applied to all units. Each unit 
is considered to be incrementally generating after it exceeds the 
capacity percent and will be credited with GS-ERCs accordingly. The GS-
ERCs in these instances are calculated by the following equation:
[GRAPHIC] [TIFF OMITTED] TP23OC15.012

    This equation quantifies the reductions of the generation shift 
from fossil steam to NGCC units by the NGCC operating rate being 
evaluated against the fossil steam standard. For all incremental NGCC 
generation the NGCC operating rate is compared against two different 
standards: (1) The NGCC standard against which ERC generation is 
evaluated; and (2) the steam standard against which GS-ERC generation 
is evaluated. An evaluation against each standard is independent of one 
another and GS-ERCs, in this situation, are only available for fossil 
steam compliance purposes.
    While having a baseline threshold for EGU generation to credit GS-
ERCs against closely resembles the EPA's BSER determination, it enables 
a system in which GS-ERCs can be generated by replacing NGCC generation 
from one unit with NGCC generation from another. In this situation 
there is not necessarily any additional NGCC generation as a 
subcategory, but a shift in which NGCC units are generating electricity 
and to what degree. This allows for a situation in which GS-ERCs can be 
generated without achieving the anticipated reductions in 
CO2 emissions.
    The EPA also requests comment on whether a distinct type of ERC 
that comes with the proposed restrictions (i.e., GS-ERCs) is necessary 
to maintain the integrity of the rate-based trading proposal. Comments 
regarding this section that solely relate to determinations finalized 
in the EGs will be considered outside the scope of this proposed rule.
3. Eligible Emission Reduction Measures for ERC Generation
    Under the rate-based federal plan, the EPA is proposing to specify 
emission reduction measures used to adjust an emission rate that are 
eligible for ERC issuance under the federal plan. Specifically, the EPA 
is proposing that RE generation that meets the requirements for 
eligible resources in the EGs (as specified in section VIII.K of the 
final EGs), meets all other requirements related to ERC issuance in the 
EGs and this proposal, and falls into one of the following specific 
categories of RE resources (as specified in section V.E of the final 
EGs), are eligible to be issued ERCs: Wind, solar, geothermal power, 
and hydropower.\58\ Further, the EPA is proposing for the federal plan 
that new nuclear units and capacity uprates at existing nuclear units 
that meet the requirements for eligible resources in the EGs (as 
specified in section VIII.K of the final EGs) and all other 
requirements related to ERC issuance in the EGs and this proposal are 
eligible to generate ERCs. Further, these RE and nuclear measures must 
have the ability to provide data from a revenue quality meter, a 
requirement that is further discussed in section IV.D.8 of this 
preamble.
---------------------------------------------------------------------------

    \58\ This treatment for RE as an eligible measure type is also 
proposed for the set-aside for RE that is part of the proposed mass-
based implementation approach co-proposed in section V of this 
preamble as the federal plan, and all proposed aspects of the 
eligible measure types described in this section and the requests 
for comment included below also apply in the mass-based set-aside 
context. Incremental nuclear is not eligible for the RE set-aside. 
The set-aside method and the use of this eligibility treatment 
within it are specified in section V.D.3 of this preamble.
---------------------------------------------------------------------------

    The EPA is proposing the inclusion of these measure types in the 
federal plan for the following reasons. These technologies, with the 
exception of nuclear, are part of the quantification of RE generation 
potential for the BSER. Thus, they are included in the quantification 
of CO2 emission performance rates and should be available to 
affected EGUs to meet their CO2 emission performance rate 
under the federal plan. See the final EGs for details on the treatment 
of these measures in BSER (see section V.E of the final EGs). These RE 
technologies are also expected to be able to deploy on an economic 
basis during the compliance period, as discussed in the final EGs (see 
section V.E.6 of the final EGs). These technologies also provide the 
simplest and most timely path for EM&V implementation under a federal 
plan, because they can use their existing metering infrastructure to 
quantify generation and submit it for ERC issuance. A concern unique to 
federal plan implementation is the need for an ERC issuance process 
that can be implemented in a streamlined manner across many 
jurisdictions in the time frame allowed by the federal plan while still 
assuring a rigorous EM&V process. By limiting eligibility to measures 
that can be directly metered, a feasible federal plan process for ERC 
issuance across a potentially large number of jurisdictions is ensured. 
This approach would allow for easier determinations of compliance with 
the requirements for EM&V proposed in section IV.D.8 of this preamble 
below (see also section VIII.K.3 of the final EGs).
    The agency requests comment on the inclusion of other emission 
reduction measures as eligible for ERC issuance under the rate-based 
federal plan. This may include other RE technologies not included 
above, such as distributed RE generation and various types of biomass. 
In this proposal, the EPA is also offering for comment a treatment 
option for biomass fuels, if it is included as an eligible measure 
under the federal plan (see below).
    The EPA requests comment on the inclusion of various types of 
demand-side EE as eligible measures for ERC issuance under the federal 
plan, such as state and utility EE programs, project-based demand-side 
EE, state building codes, state appliance standards, and conservation 
voltage reduction. The agency also requests comment on the inclusion of 
CHP as an eligible measure under the federal plan. Later in this 
section, the agency has provided detailed requirements for the issuance 
of ERCs for CHP, and we request comment on these requirements for 
inclusion in the federal plan.
    The EPA requests comment on the inclusion as eligible for ERC 
issuance under the federal plan of any other

[[Page 64995]]

emission reduction measures beyond those mentioned here, as long as 
they meet the eligibility requirements outlined in the final EGs for 
rate-based crediting. For all of the above measures on which the EPA 
requests comment, the agency is particularly interested in comments on 
how EM&V methods can be implemented for these measures across 
applicable jurisdictions in the timeframe provided by this proposal in 
a way that is rigorous, straightforward, widely demonstrated, and in 
accordance with the EM&V requirements in this proposal, outlined in 
section IV.D.8 of this preamble, and within the requirements outlined 
in the final Guidelines (see section VIII.K.3 of the final EGs). It 
should also be noted that any eligible measure will be subject to the 
eligibility requirements outlined in this proposal and the final EGs, 
including the requirement that the measure be incremental to 2012.
    The EPA acknowledges that as new technologies mature, there should 
be an avenue to add new technologies to this specified set of eligible 
measures under the federal plan. The agency requests comment on 
appropriate processes through which, after the federal plan is 
finalized, the EPA or stakeholders could demonstrate the 
appropriateness of new measure types and the EPA could evaluate and 
approve the demonstration so that a new measure type could be 
considered eligible for ERC issuance under the federal plan.
    Under the rate-based model rule, the EPA is proposing that any 
emission reduction measure is eligible as long as the requirements for 
eligible resources in the final EGs (as specified in section VIII.K of 
the final EGs) and all other requirements related to ERC issuance under 
the model rule that are specified in the EGs and this proposal. In 
particular, these measures should be able to meet the requirements for 
EM&V as finalized in the final EGs section VIII.K and those proposed 
for the model rule in section IV.D.8 of this preamble. In this section, 
the EPA is also providing detailed requirements for CHP and waste heat 
power (WHP); these requirements are proposed under the model rule, and 
we request comment on their inclusion in the federal plan. We are 
requesting comment on the inclusion of biomass and an option for the 
treatment of biomass in both the proposed rate-based federal plan and 
proposed rate-based model rule.
    As mentioned above, the EPA requests comment on the inclusion of 
biomass as an eligible measure for rate-based crediting. The EPA is 
also requesting comment on the following treatment option for biomass 
if biomass is included as an eligible measure. In the final EGs, the 
EPA recognizes that the use of some biomass-derived fuels can play an 
important role in controlling increases of CO2 levels in the 
atmosphere (see section VIII.I.C of the final EGs). The use of some 
kinds of biomass has the potential to offer a wide range of 
environmental benefits, including carbon benefits. However these 
benefits can typically be realized only if biomass feedstocks are 
sourced responsibly and attributes of the carbon cycle related to the 
biomass feedstock are taken into account. Many states have already 
recognized the importance of waste-derived feedstocks via mandatory and 
voluntary programs supporting such efforts.\59\ Some states have also 
acknowledged the potential role of certain forestry and agricultural 
industrial byproducts (such as black liquor) in energy production. Many 
states have also recognized the importance of forests and other lands 
for climate resilience and mitigation, and have developed a variety of 
sustainable forestry policies, biomass-related RE incentives and 
standards, and GHG accounting procedures.\60\
---------------------------------------------------------------------------

    \59\ Types of waste-derived biogenic feedstocks may include: 
Landfill gas generated through the decomposition of municipal solid 
waste (MSW) in a landfill; biogas generated from the decomposition 
of livestock waste, biogenic MSW, and/or other food waste in an 
anaerobic digester; biogas generated through the treatment of waste 
water, due to the anaerobic decomposition of biological materials; 
livestock waste; and the biogenic fraction of MSW at waste-to-energy 
facilities (as discussed in section VIII.I.2.C of the final EGs).
    \60\ Some states, for example Oregon and California, have 
programs that recognize the multiple benefits that forests provide, 
including biodiversity and ecosystem services protection as well as 
climate change mitigation through carbon storage. Others, like 
California's Forest Practice Regulations, support sustained 
production of high-quality timber while considering ecological, 
economic and social values. Several states focus on sustainable 
bioenergy, as seen with the sustainability requirements for eligible 
biomass in the Massachusetts renewable portfolio standard (RPS), 
which, among other requirements, limits old growth forest harvests.
---------------------------------------------------------------------------

    In addition to acknowledging such state programs, the EPA has 
undertaken a technical assessment of biogenic CO2 emissions 
from stationary sources associated with the production, processing and 
use of biomass fuels. In November 2014, the agency released a second 
draft of the technical report, Framework for Assessing Biogenic Carbon 
Dioxide for Stationary Sources. The revised Framework, and the EPA's 
Science Advisory Board (SAB) peer review of the 2011 Draft Framework, 
concluded that it is not scientifically valid to assume that all 
biogenic feedstocks are ``carbon neutral'' and that the net biogenic 
CO2 atmospheric contribution of different biogenic 
feedstocks generally depends on various factors related to feedstock 
characteristics, production, processing and combustion practices, and, 
in some cases, what would happen to that feedstock and the related 
biogenic emissions if not used for energy production.\61\ The EPA is 
engaging in a second round of targeted peer review on the revised 
Framework with the SAB in 2015.\62\ Information in the revised 
Framework and the second SAB peer review process, including stakeholder 
comments, will assist the EPA in assessing potential qualified biomass 
feedstocks in federal plan applications.
---------------------------------------------------------------------------

    \61\ Specifically, the SAB found that ``There are circumstances 
in which biomass is grown, harvested and combusted in a carbon 
neutral fashion but carbon neutrality is not an appropriate a priori 
assumption; it is a conclusion that should be reached only after 
considering a particular feedstock's production and consumption 
cycle. There is considerable heterogeneity in feedstock types, 
sources and production methods and thus net biogenic carbon 
emissions will vary considerably. Of course, biogenic feedstocks 
that displace fossil fuels do not have to be carbon neutral to be 
better than fossil fuels in terms of their climate impact.'' http://www.epa.gov/climatechange/ghgemissions/biogenic-emissions.html.
    \62\ http://www.epa.gov/sab.
---------------------------------------------------------------------------

    If biomass is included as an eligible measure, we are taking 
comment on an option for biomass treatment under the rate-based federal 
plan, which would also potentially apply to eligible generation under 
the proposed mass-based model trading rule allowance set-aside and to 
the calculation of covered emissions for affected EGUs that are co-
firing biomass.
    This option offered for comment is to specify a list of pre-
approved qualified biomass fuels. For example, the EPA could recognize 
the CO2 and climate policy benefits of waste-derived 
feedstocks (e.g., landfill gas) and certain industrial byproduct 
feedstocks (e.g., black liquor or other forestry and agricultural 
industrial byproducts with no alternative markets). As another example, 
the EPA could also recognize biomass feedstocks from sustainably 
managed forest lands, provided that these feedstocks meet certain 
requirements such as demonstration that the feedstock is sourced from 
sustainably managed lands (for example, feedstocks from forest lands 
with sustainable practices like improved management to increase carbon 
sequestration benefits) and therefore helps control increases of 
CO2 in the atmosphere. The pre-approved qualified biomass 
feedstocks list could be amended in the future as the science related 
to biogenic CO2 emissions assessments evolves. The EPA asks 
for

[[Page 64996]]

comment on whether to include a provision that allows sources to seek 
approval for other types of biomass to be added to the pre-approved 
list and what that process would entail. For example, this process 
could include consideration of the production, processing and use of 
forest- and agriculture-derived biomass fuels and related 
CO2 benefits.
    The EPA also requests comment on options for how EGUs would 
demonstrate that feedstocks meet the requirements to be accepted as a 
pre-approved qualified biomass feedstocks. These requirements could 
include demonstration of certification or verification of practices 
that are additional to other monitoring, reporting and EM&V 
requirements discussed in this proposal, such as provision of 
sufficient credible analysis of carbon benefits, third party 
verification and/or certification, or a determination of the net 
biogenic CO2 effects related to the production, processing 
and use of the feedstock.
    The EPA requests broad comment on the types of qualified biomass 
feedstocks that should be specified in the final model rule, if any. We 
request comment on the methods that we should specify in the final 
model rule for the measurement of the associated biogenic 
CO2 for such feedstocks, as well as what other requirements 
we should specify in the final model rule related to biomass. 
Specifically, we seek comment on the level of detail provided and 
whether more or less detail (and what detail) should be included in the 
final model rule. We request comment on any other requirements that 
should be included in the final model rule regarding EM&V for qualified 
biomass. Discussion of the biomass EM&V requirements in the rate-based 
model rule can be found in section IV.D.8 of this preamble below.
    The eligibility requirements for ERC resources discussed in this 
section meet the requirements outlined in the final EGs (see section 
VIII.K.2 of the final EGs). The agency in this proposal is including in 
the regulatory text for the model rule language related to the 
crediting of these other potential ERC resources, even though they are 
not being proposed as a part of the federal plan. Our intent is to 
provide states further direction through the model rule on how states 
may include this broader set of ERC-generating resources in a rate-
based plan. To reduce confusion over the applicability of these 
provisions, the agency has added a note in the regulatory text to 
clarify that these resources, and provisions throughout the proposed 
subpart that are related to those resources, are not applicable in the 
case of a federal plan. Rather they are proposed as part of the model 
trading rule only. However, again, the agency requests comment on the 
inclusion of these resources in the federal plan.
    The EPA is proposing with respect to the rate-based model rule that 
CHP units are eligible to generate ERCs. With respect to the federal 
plan, the EPA requests comment on the incorporation of non-affected CHP 
units. Electric generation from non-affected CHP units \63\ may be used 
to adjust the CO2 emission rate of an affected EGU, as CHP 
units are low-emitting electric generating resources that can replace 
generation from affected EGUs. Electrical generation from non-affected 
CHP units that meet the eligibility criteria under section VIII.K.1.a 
of the Clean Power Plan preamble can be used to adjust the reported 
CO2 emission rate of an affected EGU.
---------------------------------------------------------------------------

    \63\ The accounting treatment described in this section is for a 
``topping cycle'' CHP unit. A topping cycle CHP unit refers to a 
configuration where fuel is first used to generate electricity and 
then heat is recovered from the electric generation process to 
provide additional useful thermal and/or mechanical energy. A CHP 
unit can also be configured as a ``bottoming cycle'' unit. In a 
bottoming cycle CHP unit, fuel is first used to provide thermal 
energy for an industrial process and the waste heat from that 
process is then used to generate electricity. Some waste heat power 
(WHP) units are also bottoming cycle units and the accounting 
treatment for bottoming cycle CHP units is provided with the WHP 
description below.
---------------------------------------------------------------------------

    The electrical generation from a non-affected CHP unit that can be 
used to adjust the CO2 emission rate of an affected EGU must 
be calculated in accordance with the method specified in this section. 
The CHP unit's electrical output is prorated based on the 
CO2 emission rate of the electrical output associated with 
the CHP unit (a CHP unit's ``incremental CO2 emission 
rate'') compared to a reference CO2 emission rate.\64\ This 
``incremental CO2 emission rate'' related to the electric 
generation from the CHP unit would be relative to the applicable 
CO2 rate-based emission standard for affected EGUs in the 
state and would be limited to values between 0 and 1. The CHP unit's 
electrical output is prorated as follows:
---------------------------------------------------------------------------

    \64\ The applicable CO2 rate-based emission standard 
is in Table 6 of this preamble.

Prorated MWh = (1-incremental CHP electrical emission rate/applicable 
---------------------------------------------------------------------------
affected EGU rate-based emission standard)* CHP MWh output

    Where the ratio is limited to values between 0 and 1.
    The CHP electrical CO2 emission rate is the net emission 
rate when the CHP unit's CO2 emissions related to its 
thermal output are deducted from the CHP unit's total CO2 
emissions. The CHP electrical CO2 emission rate is derived 
as follows:

CHP electrical CO2 emission rate = [CHP fuel input \65\ * 
fuel emission factor \66\ - (UTO/boiler efficiency) * fuel emission 
factor]/CHP electrical MWh
---------------------------------------------------------------------------

    \65\ This term generally represents the thermal energy 
associated with the total fuel input.
    \66\ The fuel emission factor can be determined through 40 CFR 
part 75 Appendix G.

    Where UTO is the useful thermal output from a counterfactual 
industrial boiler that would have existed to meet thermal load in the 
absence of the CHP unit.
    This accounting approach takes into account the fact that a non-
affected CHP unit is a fossil fuel-fired emission source, as well as 
the fact that the incremental CO2 emissions related to 
electrical generation from a non-affected CHP unit are typically very 
low. To generate ERCs for CHP, the CHP Electrical CO2 
Emission Rate that is calculated (from above) is applied against the 
applicable affected EGU standards in the same fashion as described in 
section IV.C.1 of this preamble. The low CO2 emission rate 
for electrical generation from a non-affected CHP unit is a product of 
both the fact that CHP units are typically very thermally efficient and 
the fact that a portion of the CO2 emissions from a non-
affected CHP unit would have occurred anyway from an industrial boiler 
used to meet the thermal load in the absence of the CHP unit. In 
contrast, the CHP unit also provides the benefit of electricity 
generation while resulting in very low incremental CO2 
emissions beyond what would have been emitted by an industrial boiler. 
As a result, the accounting method does not presume that emission 
reductions occur outside the electric power sector, but instead only 
accounts for the CO2 emissions related to the electrical 
production from a CHP unit that is used to substitute for electrical 
generation from affected EGUs.
    The EPA is proposing with respect to the rate-based model rule that 
WHP units are eligible to generate ERCs. With respect to the federal 
plan, the EPA requests comment on the incorporation of non-affected WHP 
units. WHP units that meet the eligibility criteria under section 
VIII.K.1 of the Clean Power Plan preamble may be used to adjust the 
CO2 emission rate of an affected EGU. There are several 
types of WHP units. There are units, also referred to as bottoming 
cycle CHP units, where the fuel is first used to provide thermal energy 
for an industrial process and the waste heat

[[Page 64997]]

from that process is then used to generate electricity.\67\ There are 
also WHP units where the waste heat from the initial combustion process 
is used to generate additional power. Under both configurations, unless 
the WHP unit supplements waste heat with fossil fuel use, there is no 
additional fossil fuel used to generate this additional power. As a 
result, there are no incremental CO2 emissions associated 
with that additional power generation. As a result, the incremental 
electric generation output from the WHP units could be considered non-
emitting, for the purposes of meeting the EGs, and the MWh of 
electrical output could be used to adjust the CO2 emission 
rate of an affected EGU.\68\ The MWh of electrical output from a WHP 
unit that can be recognized may not exceed the MWh of industrial or 
other thermal load that is being met by the WHP unit, prior to the 
generation of electricity.\69\ In addition, where fossil fuel is used 
to supplement waste heat in a WHP application, the EPA requests comment 
on what provisions to include in the final model rule to prorate the 
proportion of fossil fuel heat input to total heat input that is used 
by the WHP unit to generate electricity. The EPA also solicits comments 
on other potential accounting mechanisms for WHP. As noted above, the 
EPA requests comment incorporating WHP as an ERC generating resource 
for the federal plan.
---------------------------------------------------------------------------

    \67\ In such a configuration, the waste heat stream could also 
be generated from a mechanical process, such as at natural gas 
pipeline compressors.
    \68\ This only applies where no additional fossil fuel is used 
to supplement the use of waste heat in a WHP facility. Where fossil 
fuel is used to supplement waste heat in a WHP application, MWh of 
electrical generation that can be used to adjust the CO2 
emission rate of an affected EGU must be prorated based on the 
proportion of fossil fuel heat input to total heat input that is 
used by the WHP unit to generate electricity.
    \69\ This limitation prevents oversizing the thermal output of a 
WHP unit to exceed the useful industrial or other thermal load it is 
meeting, prior to generation of electricity.
---------------------------------------------------------------------------

D. ERC Tracking and Compliance Operations

    The EPA proposes that the rate-based federal trading program use 
the agency's already-existing Allowance Tracking and Compliance System 
(ATCS). Under the proposed rate-based trading program, the federal 
trading program would be maintained in the EPA's existing data system. 
The ATCS would be used to track the trading of ERCs held by affected 
EGUs, as well as ERCs held by other entities. Specifically, the ATCS 
would track the generation of ERCs, holdings of ERCs in compliance 
accounts (i.e., accounts for affected EGUs) and general accounts (i.e., 
accounts for other entities and for affected EGUs, including affected 
EGUs that are under a ready-for-interstate-trading state plan), 
deduction of ERCs for compliance purposes, and transfers of ERCs 
between accounts. The primary role of the ATCS is to provide an 
efficient, automated means for covered sources to comply, and for the 
EPA to determine whether covered sources are complying with the 
emission rate standards. The ATCS would also provide data to the ERCs 
market and the public, including a record of ownership of ERCs, dates 
of ERC issuance, ERC transfers, buyer and seller information, serial 
numbers of ERCs transferred, emissions data, and compliance 
information. This information would be publicly available on the EPA's 
Web site and in annual progress reports. The ATCS and the EPA would 
provide all required elements of a qualified ERC tracking system as 
described in section VIII of the final EGs.
    In the subsections that follow, the mechanisms by which a rate-
based trading program would be implemented and administered are 
detailed. The EPA requests comment on each component of the trading 
system that is proposed in this preamble and the associated model rule, 
the trading program as a whole, and specifically requests comment on 
means to expedite the process of issuing ERCs, any minimum and maximum 
periods for which ERCs should be issued (e.g., monthly, quarterly, 
annually), and any means to ensure that the ERCs issued meet the 
requirements of the EGs and these proposed rules. The rate-based 
federal plan and model rule borrow many concepts from other successful 
trading programs, and the agency is interested in receiving additional 
information through comments on successful implementation of similar 
programs.
1. Designated Representatives and Alternate Designated Representatives
    This section establishes the procedures for certifying and 
authorizing the designated representative, and alternate designated 
representative, of the owners and operators of the affected EGU and for 
changing the designated representative and alternate designated 
representative. These sections also describe the designated 
representative's and alternate designated representative's 
responsibilities and the process through which he or she could delegate 
to an agent the authority to make electronic submissions to the 
Administrator. These provisions would be patterned after the provisions 
concerning designated representatives and alternates in prior EPA-
administered trading programs.
    The designated representative would be the individual authorized to 
represent the owners and operators of each affected EGU in matters 
pertaining to the rate-based trading program. One alternate designated 
representative could be selected to act on behalf of, and legally bind, 
the designated representative and, thus, the owners and operators. 
Because the actions of the designated representative and alternate 
would legally bind the owners and operators, the designated 
representative and alternate would have to submit a certificate of 
representation certifying that each was selected by an agreement 
binding on all such owners and operators and was authorized to act on 
their behalf.
    The designated representative and alternate would be authorized 
upon receipt by the Administrator of the certificate of representation. 
This document, in a format prescribed by the Administrator, would 
include: Specified identifying information for the covered source and 
covered EGUs at the source and for the designated representative and 
alternate; the name of every owner and operator of the affected EGU; 
and certification language and signatures of the designated 
representative and alternate. All submissions (e.g., monitoring plans, 
monitoring system certifications, and allowance transfers) for an 
affected EGU would have to be submitted, signed, and certified by the 
designated representative or alternate. Further, upon receipt of a 
complete certificate of representation, the Administrator would 
establish a compliance account in the ATCS for the affected EGU 
involved.
    In order to change the designated representative or alternate, a 
new certificate of representation would have to be received by the 
Administrator. A new certificate of representation would also have to 
be submitted to reflect changes in the owners and operators of the 
affected EGU involved. However, new owners and operators would be bound 
by the existing certificate of representation even in the absence of 
such a submission.
    In addition to the flexibility provided by allowing an alternate to 
act for the designated representative (e.g., in circumstances where the 
designated representative might be unavailable), additional flexibility 
would be provided by allowing the designated representative and 
alternate to delegate authority to make electronic submissions on his 
or her behalf. The designated representative and alternate could 
designate agents to submit

[[Page 64998]]

electronically certain specified documents. The previously-described 
requirements for designated representatives and alternates would 
provide regulated entities with flexibility in assigning 
responsibilities under the rate-based trading program, while ensuring 
accountability by owners and operators and simplifying the 
administration of the proposed rate-based trading program.
2. ERC Tracking and Compliance System
    The rate-based trading program rules establish the procedures and 
requirements for using and operating the ATCS (which is the electronic 
data system through which the Administrator would handle ERC issuance, 
holding, transfer, and deduction), and for determining compliance with 
the ERC-holding requirements in an efficient and transparent manner. 
The ATCS provides a record of ownership, dates of ERC transfers, buyer 
and seller information, origin of ERCs, the serial numbers of ERCs 
transferred, and ERC type (i.e., if it is a GS-ERC or not). ERC price 
information would not be included in the ATCS. The EPA's experience is 
that private parties (e.g., brokers) are in a better position to obtain 
and disseminate timely, accurate price information than the EPA. For 
example, because not all ERC transfers are immediately reported to the 
Administrator, the Administrator would not be able to ensure that any 
reported price information associated with the transfers would reflect 
current market prices.
3. Tracking System Requirements
    This federal plan and model rule's proposed tracking system and 
tracking systems that will be presumptively approvable for state plans 
fufill the criteria set forth in the final EGs. The EPA's tracking 
system includes provisions to ensure that ERCs issued to any eligible 
entity are properly tracked from issuance to submission by affected 
EGUs for compliance (where ERCs are ``surrendered'' by the owner or 
operator of an affected EGU and ``retired'' or ``cancelled'' by the 
Administrator or administering state regulatory body), to ensure they 
are used only once to meet a regulatory obligation. This is addressed 
through specified requirements for tracking system account holders, ERC 
issuance, ERC transfers among accounts, compliance true-up for affected 
EGUs,\70\ and an accompanying tracking system infrastructure design. 
Each issued ERC will have a unique identifier (i.e., serial number) and 
the tracking system will provide traceability of issued ERCs back to 
the program or project for which they were issued.
---------------------------------------------------------------------------

    \70\ ``Compliance true-up'' refers to ERC submission by an owner 
or operator of an affected EGU to adjust a reported CO2 
emission rate, and determination of whether the adjusted rate is 
equal to or lower than the applicable rate-based emission limit.
---------------------------------------------------------------------------

    The EPA received a number of comments from states and stakeholders 
on the Clean Power Plan about the value of the EPA's support in 
developing and/or administering tracking systems to support state 
administration of rate-based emission trading systems. As described 
above in section III.A of this preamble, the EPA is proposing, as part 
of both types of model trading rules, a federal trading platform that 
would allow state plans that are ready-for-interstate-trading to 
operate through a program in which the EPA provides the tracking and 
compliance system. This system will meet the requirements of the Clean 
Power Plan.
4. Compliance and General Accounts
    This section describes two types of ATCS accounts: Compliance 
accounts, which would be established by the Administrator for each 
affected EGU upon receipt of the certificate of representation for the 
source; and general accounts, which could be established by any entity 
upon receipt by the Administrator of an application for a general 
account. A compliance account would be the account in which any ERCs 
used by the affected EGU for compliance with the emissions limitations 
would have to be held until retired for compliance.
    General accounts could be used by any person or group for holding 
or trading ERCs. However, ERCs could not be used for compliance with 
emissions limitations so long as the ERCs were held in, and not 
properly and timely transferred out of, a general account. To open a 
general account, a person or group would be required to submit an 
application for a general account, which would be similar in many ways 
to a certificate of representation. The application would include, in a 
format to be prescribed by the Administrator: The name and identifying 
information of the individual who would be the authorized account 
representative and of any individual who would be the alternate 
authorized account representative; an identifying name for the account; 
the names of all persons with an ownership interest with the respect to 
allowances held in the account; and certification language and 
signatures of the authorized account representative and alternate. The 
authorized account representative and alternate would be authorized 
upon receipt of the application by the Administrator. The provisions 
for changing the authorized account representative and alternate, for 
changing the application to take account of changes in the persons 
having an ownership interest with respect to ERCs, and for delegating 
authority to make electronic submissions would be analogous to those 
applicable to comparable matters for designated representatives and 
alternates. The EPA requests comment on these compliance mechanisms.
5. Compliance Demonstration
    The EPA proposes that affected EGUs subject to this federal plan 
are required to meet compliance obligations by November 1 of the year 
following the end of the compliance period. For an affected EGU to meet 
its compliance obligations its average stack emission rate over the 
compliance period must be at or below its applicable rate standard, or 
the affected EGU must use ERCs to adjust its average stack emission 
rate to be at or below its applicable rate standard. An EGU's average 
emission rate over the compliance period will be calculated based on 
submitted data to ATCS. The compliance period average would be 
calculated by taking the measured CO2 mass in units of 
pounds (lbs) summed over the compliance period for an affected EGU and 
dividing it by the total net energy output over the compliance period 
for that affected EGU in units of MWh.\71\ This averaged emission rate 
will be compared to the emissions standards that the affected EGU is 
subject to during the corresponding compliance period. Accordingly, and 
if necessary, the appropriate number of ERCs will be retired from the 
affected EGU's compliance account to adjust the emission rate of the 
affected EGU to be equal to the emission standard. The discussion of 
using ERCs for compliance is found in section IV.D.10 of this preamble.
---------------------------------------------------------------------------

    \71\ Note that affected EGUs will submit these values to the EPA 
and the values will go through a transparent review process.
---------------------------------------------------------------------------

6. Recordation of ERC Generation and ERC Issuance
    The EPA proposes to issue ERCs for ERC generating entities once per 
year. Thus, in a 3-year compliance period, for instance, there would be 
three points at which the agency issues ERCs. After

[[Page 64999]]

each calendar year, the EPA would calculate the ERCs generated for 
affected EGU and non-EGU ERC generators based on data submitted to the 
EPA through the Emissions Collection and Monitoring Plan System 
(ECMPS). These calculated ERC quantities would be proposed as part of a 
Notice of Data Availability (NODA) with a 30-day comment period. 
Subsequently, the EPA would finalize this NODA and issue ERCs in 
accordance with the NODA, with tracking and serial numbers. For 
affected EGUs with compliance accounts, the ERCs would be issued to 
these. For entities without compliance accounts, the EPA would issue 
ERCs to an entity's general account. The timing for issuing ERCs would 
be consistent with existing programs, and the EPA believes there is 
value in consistency. However, we solicit comment on the annual 
issuance of ERCs and whether issuance should occur at different 
intervals (e.g., quarterly, biannually, or other time frames). The EPA 
requests justification along with corresponding comments regarding ERC-
issuance intervals. We request comment on how reporting and 
recordkeeping requirements could be minimized, particularly for small 
entities, to the extent possible under the statute and existing 
regulations.
    a. Issuance of ERCs to Affected EGUs. Following the determination 
of the number of ERCs an affected EGU is eligible to receive, based on 
an affected EGU's reported CO2 emission rate compared to a 
specified reference rate,\72\ the EPA will issue those ERCs into the 
affected EGU's compliance account in ATCS. The issuance will occur 
annually through the NODA process. ERCs will have a unique serial 
number, tracking number, and will distinguish ERC type (i.e., if it is 
BB2 or not) when issued to an affected EGU.
---------------------------------------------------------------------------

    \72\ As described in section IV.C.1 of this preamble.
---------------------------------------------------------------------------

    b. Issuance of ERCs for Measures Used to Adjust an Emission Rate. 
In the final EGs, the EPA has specified requirements for an ERC 
issuance process for the quantification and verification of measures 
used to adjust an emission rate that provide the necessary rigor and 
transparency while being efficient and streamlined. This is the intent 
of the federal plan as well, where there is a particular concern with 
implementing a streamlined and efficient federal process for ERC 
issuance across federal plan states. As required in the final EGs, we 
are proposing a two-step application process to the federal plan 
tracking systems for ERCs that allows for project approval to take 
place prior to the performance period, and makes the issuance of ERCs 
as quick and efficient as possible after generation has been quantified 
and verified, while still assuring a rigorous approval process. For the 
first step in the ERC issuance application process, the EPA proposes 
that RE and nuclear generation providers submit to the EPA or its 
designated agent an eligibility application for EPA approval, 
demonstrating that the project is eligible for the issuance of credits, 
including an EM&V plan that meets EPA requirements. The EPA requests 
comment on all aspects of the proposed ERC issuance process. The EPA 
also requests comment on how an ERC issuance process would apply to 
emission reduction measures for which we are requesting comment 
regarding their eligibility for ERC issuance under the federal plan, 
including types of RE not covered by the federal plan, demand-side EE, 
CHP, WHP, biomass, and any other measure that could be considered 
eligible under the final guidelines.
    The following are proposed required components of the eligibility 
application, as specified for these measures in the final EGs:

    (1) The EPA proposes that the federal plan will require that 
providers must show that the generation they would be providing to 
the federal plan system for ERC issuance is only being credited in 
the federal plan, and will not be submitted for ERC issuance in any 
other rate-based crediting system in any other state. As discussed 
in section IV.C. of this preamble, we are proposing that states with 
rate-based emission standards plans that have eligibility and EM&V 
requirements compatible with the federal plan would have the 
opportunity to participate in the federal plan trading systems, and 
create a shared pool of creditable reductions, in which case credits 
approved by such states would be eligible for use by affected EGUs 
in the federal plan.
    (2) The provider must show that the project is using an eligible 
RE or nuclear resource. Specific requirements are proposed in 
section IV.C of this preamble.
    (3) The provider must show that the project has an EM&V plan 
that meets the federal plan requirements. Proposed requirements 
specific to the federal plan are proposed in section IV.D.8 of this 
preamble. As specified in section IV.D.8 of this preamble, we 
request comment on whether nuclear energy resources should be 
subject to the same EM&V requirements as RE resources, and if not, 
we request comment on the EM&V requirements to which nuclear energy 
resources should be subject.
    (4) There are special conditions if the provider is located in a 
state with a mass-based plan. For eligible RE capacity, the provider 
can only be credited in a rate-based state or rate-based multi-state 
system if the provider can demonstrate that the generation was 
produced to meet electricity load in a state with a rate-based plan. 
The EPA is proposing that an RE provider can make this demonstration 
by providing documentation of a power purchase agreement or delivery 
contract from the rate-based state and show that the measure was 
treated as a generation resource used to serve regional load that 
included the rate-based state. For incremental nuclear capacity, no 
provider in a state with a mass-based plan can be eligible for ERC 
issuance in a rate-based state. This requirement and the 
justification for its inclusion is further discussed in section 
III.A of this preamble on Interstate Effects and also discussed in 
the Interstate Effects section of the final EGs (see sections 
VIII.K.1 and VIII.L). The EPA is proposing that there would be no 
other geographic limitation on the location of the providers of RE 
and incremental nuclear generation submitted for ERC issuance under 
the rate-based federal plan approach.
    (5) This application must include an independent third-party 
verifier's review and approval of the eligibility requirements, as 
is reflected in EM&V requirements for the final guidelines, and 
specified as part of the proposed federal plan EM&V requirements in 
section IV.D.8 of this preamble.

    We request comment on each criterion of the eligibility application 
described herein and in the proposed model rule, for each eligible 
resource. Specifically, we seek comment on the substantive content of 
the criteria, and we seek comment on the level of detail provided and 
whether more or less detail (and what detail) should be included in the 
final model rule.
    The EPA is proposing that ERCs would be tracked in the ATCS. 
Additionally, the EPA is proposing that the agency would establish a 
complementary tracking system for the ERC issuance process. It would 
provide for transparent access to RE project and program eligibility 
applications and regulatory approvals as well as information on the 
activities of accredited third party verifiers (third party verifiers 
are further discussed in section IV.D.7 of this preamble), as well for 
the public to be able to generate reports based on this information.
    The agency is proposing that the project eligibility applications 
would be accepted after the finalization of the federal plan and prior 
to the first compliance period, as soon as the agency is able to 
establish an application process, and that applications would be 
accepted on an annual basis. The agency requests comment on whether a 
quarterly or biannual application process is more appropriate. These 
applications would be accepted through the entirety of all compliance 
periods. The EPA will review and approve the project applications. It 
is proposed that the EPA

[[Page 65000]]

may designate an agent to coordinate the project application process 
and assist with review of applications.
    For the second step in the credit issuance application process, the 
EPA proposes that providers submit an M&V report to the EPA, or its 
designated agent, prior to the EPA's issuance of ERCs. This can only 
occur after the approval of a project application, the RE has been 
generated, and necessary EM&V has been completed.
    The following are proposed required components of the M&V Report:

    (1) Documentation of completed EM&V in accordance with the EM&V 
plan submitted by the RE or nuclear provider, including 
quantification of the MWh of generation to be credited and 
verification of their creation.
    (2) Documentation that the generation has not been submitted for 
crediting under any other federal or state plan, including to 
another rate-based credit tracking system.
    (3) Documentation that the MWh resulted from RE or incremental 
nuclear capacity eligible for crediting under the federal plan 
requirements and in accordance with final EGs. This documentation 
should note if the MWh are from an RE project located in a state 
with a mass-based plan, and show if the generation is approved to be 
eligible for ERC issuance under the federal plan. See above 
geographic eligibility discussion and section III.A of this preamble 
for specifics on the required demonstration for this type of RE 
generation. As discussed in that section, this option is proposed to 
not be available to incremental nuclear capacity located in a state 
with a mass-based plan.
    (4) This application must include a verification report from an 
independent third-party verifier, submitted after the verifier's 
review and approval of the eligibility application, as is reflected 
in EM&V requirements for the final guidelines, and specified as part 
of proposed federal plan EM&V requirements described below and 
included in detail in the proposed model rule.

    If the application meets these requirements, pursuant to review by 
the EPA or its designated agent, ERCs will be issued to the provider by 
the EPA through the ATCS. The specific steps of the process by which an 
eligible resource seeks ERCs, and by which an affected EGU may use ERCs 
in its compliance demonstration, are described in the proposed model 
rule. One of the steps requires the proponent to register for a general 
account in the EPA tracking system where the ERCs would be recorded. 
See 40 CFR 62.16515 for the requirements to establish a general 
account. While EPA is proposing to allow eligible resources to use a 
general account to receive any ERCs issued under this section, the EPA 
requests comment on extending the designated representative provisions 
in 40 CFR 62.16485 to eligible resources instead of the general account 
provisions. Requiring eligible resources to submit information similar 
to that collected in the certificate of representation in 40 CFR 
62.16500 and to appoint a designated representative to act on behalf of 
all owners/operators for all projects requesting ERCs may improve the 
EM&V process by making the eligible resources more accountable.
    Because it is critical to the integrity of an ERC that it 
represents the actual MWh of energy generated or saved that it purports 
to represent, and as required in the EGs for state plans, the federal 
plan and model rule include provisions to address error correction 
(i.e., mechanisms to adjust the number of ERCs issued based on all form 
of errors, e.g., clerical errors, over- and under-statements, material 
inconsistency with rule provisions, fraud, etc.). In addition, the 
federal plan and model rule include provisions that provide that, at 
any time for cause, the EPA may temporarily or permanently revoke the 
qualification status of eligible resources from being issued ERCs for 
at least the duration it does not meet the requirements for being 
issued ERCs and independent verifiers from providing verification 
services for at least the duration it does not meet the requirements of 
the state plan. For the federal plan, as discussed in section III.I of 
this preamble above, we propose to use the administrative appeals 
process set forth 40 CFR part 78 to address party-specific disputes 
concerning the issuance or validity of ERCs. States may adopt a similar 
procedural and substantive process at the state level to enable them to 
rescind or withhold approval of specific credits. We request comment on 
the content of each of these provisions in the model rule, and 
specifically seek comment on whether the model rule should include 
different or additional details related to either procedure or 
substance for error correction and the revocation of the qualification 
status of an eligible resource or independent verifier.
    The agency is proposing that M&V reports will be accepted starting 
before the beginning of the first compliance period (January 1, 2022), 
through an application process the agency will establish and 
administer, and that applications will be accepted on an annual basis. 
These applications will be accepted through the entirety of all 
compliance periods. The EPA will review and approve M&V reports, and 
may designate an agent to coordinate and assist with M&V reports. The 
EPA is proposing that it will issue ERCs for a given year no later than 
6 months after the end of the relevant year. This amount of time may be 
necessary to accommodate the ERC issuance process, including necessary 
EM&V. The overall proposed schedule for trading and true-up has been 
constructed to allow for this period of time for EM&V after the 
compliance period.
    For purposes of the proposed rate-based federal plan, the EPA 
proposes to implement the CEIP on behalf of a state by issuing early 
action ERCs for eligible actions located in or benefitting that state 
that are implemented after September 6, 2018 and that generate zero-
emitting MWh or reduce energy demand in 2020 and/or 2021.\73\ The EPA 
intends to implement the program in a way that maintains the stringency 
of the rate-based emission standards for affected EGUs in the 
compliance periods established in this rule. For the purposes of the 
rate-based federal plan, the EPA is proposing to award early action 
ERCs to two types of eligible projects, as listed below. The rationale 
for including these projects is included in section VIII.B.2 of the 
final EGs.
---------------------------------------------------------------------------

    \73\ As discussed in section VIII.B.2 of the final EGs, in the 
case of a state that submits a final state plan including 
requirements for the state's participation in the CEIP, eligible RE 
projects may commence construction, and eligible EE projects may 
commence implementation, following the date of submission of a final 
state plan to the EPA. These projects must be implemented in or 
benefit the state that submitted the final state plan to the EPA, 
and may receive incentives for the zero-emitting MWh they generate 
or the end-use energy savings they achieve during 2020 and/or 2021.
---------------------------------------------------------------------------

     RE investments that generate metered MWh from any type of 
wind or solar resources; and
     Demand-side EE programs and measures implemented in low-
income communities that result in quantified and verified electricity 
savings (MWh).
    The EPA proposes the following framework to implement the CEIP in 
the rate-based federal plan. First, the EPA proposes to implement a 
mechanism for issuing early action ERCs for eligible RE projects that 
commence construction and eligeible EE projects that commence 
implementation after September 6, 2018 and that generate zero-emitting 
MWh or reduce end-use energy demand during 2020 and/or 2021. These 
projects must be located in or benefit the state on whose behalf the 
EPA is implementing the federal plan. The EPA proposes to design this 
mechanism in a manner that would have no impact on the aggregate 
emission performance of sources required to meet rate-based emission 
standards during the compliance periods. The EPA requests comment on 
the structure of this mechanism, which could include adjusting the 
stringency of the emission standards during the compliance periods to 
account for the issuance of early action ERCs for MWh

[[Page 65001]]

generated or avoided in 2020 and/or 2021. For example, during the 
interim performance period, a number of ERCs could be retired in an 
amount equivalent to the number of early action ERCs that were awarded 
for MWh generated or avoided in 2020 and/or 2021. As another option, 
the EPA, or a state under the model trading rule, could adjust their 
targets to achieve the same stringency, taking into account the 
additional borrowed ERCs. The EPA requests comments on all potential 
methods to adjust state targets, including modeling-based approaches, 
and on what information the state must present to demonstrate that the 
new targets preserve the needed stringency. More generally, the EPA 
requests comments on these ideas, as well as on alternatives for 
maintaining the stringency of a rate-based plan implementing the CEIP 
so as to have no impact on the aggregate emission performance of 
sources required to meet rate-based emission standards during the 
compliance periods.
    Second, the agency proposes to create an account of ``matching'' 
ERCs for each state participating in the CEIP--regardless of whether a 
state is implementing a state plan or the agency is implementing a 
federal plan on its behalf. This distribution would reflect each 
state's pro rata share--based on the amount of the reductions from 2012 
levels the affected EGUs in the state are required to achieve relative 
to those in the other participating states--of a federal pool of 
additional ERCs, which would be limited to the equivalent of 300 
million short tons of CO2 emissions. Thus, states whose 
affected EGUs have greater reduction obligations will be eligible to 
secure a larger proportion of the federal pool upon demonstration of 
quantified and verified MWh of RE generation or demand side-EE savings 
from eligible projects realized in 2020 and/or 2021. The EPA intends 
that a portion of these matching ERCs would be reserved for eligible 
wind and solar projects, and a portion would be reserved for eligible 
EE projects implemented in low-income communities. The agency 
recognizes that there have been historical economic, logistical and 
information barriers to implementing EE programs in these communities, 
and therefore believes it is appropriate to reserve a portion of the 
federal pool to incentivize investment in these programs. The EPA 
requests comment on the size of reserve of matching ERCs for eligible 
low-income EE programs as well as for eligible wind and solar projects. 
The EPA is proposing that unused ERCs in either reserve would be 
redistributed among participating states. This redistribution could be 
executed according to the pro rata method discussed above. 
Alternatively, unused matching EE or RE ERCs could be swept back into a 
federal pool and distributed to project providers on a first-come, 
first served basis. EPA requests comment on these ideas as well as 
alternative proposals regarding the method for redistributing matching 
ERCs, as well as the appropriate timing for such a redistribution.
    Following the effective date of a rate-based federal plan for a 
state, the agency will create an account of matching ERCs for the state 
that reflects the pro rata share of the 300 million short ton 
CO2 emissions-equivalent matching poolthat the state is 
eligible to receive. Any matching ERCs that remain undistributed after 
September 6, 2018 will be distributed to those states with approved 
state plans that include requirements for CEIP participation, as well 
as to those states on whose behalf EPA is implementing a federal plan. 
These ERCs will be distributed according to the pro rata method 
outlined above. Unused matching ERCs that remain in the accounts of 
states participating in the CEIP on January 1, 2023, will be retired by 
the EPA.
7. Independent Verifiers
    The EPA has determined in the final EGs that independent 
verification requirements are necessary to ensure the integrity of any 
rate-based emission trading program, given the types of eligible 
measures that may generate ERCs and the broad geographic locations in 
which those measures may occur. Inclusion of an independent 
verification component provides technical support for the EPA in the 
context of the proposed federal plan, and the states in the context of 
their plans, to ensure that eligibility applications and monitoring and 
verification reports are appropriately reviewed prior to issuance of 
ERCs. Inclusion of an independent verification component is also 
consistent with similar approaches required by state PUCs for the 
review of demand-side EE program results and GHG offset provisions 
included in state GHG emission budget trading programs.
    The remainder of this section and the related language in the 
proposed model rule provide the proposed basis by which the EPA intends 
to evaluate the independence of the verifiers that it uses to provide 
verification reports pursuant to the federal plan. The qualifications 
described here and in the model rule would be presumptively approveable 
in the context of a state plan.
    As a starting point, an independent verifier must have the 
necessary technical qualifications to provide verification services for 
the subject in question, as well as fulfill certain codes of conduct in 
providing verification services. Only verifiers approved or 
``accredited'' by the EPA may provide verification services related to 
ERC issuance for the federal plan, in the same way that only verifiers 
approved by a state may be eligible to perform verification services 
pursuant to a state plan.\74\
---------------------------------------------------------------------------

    \74\ In this section, the term ``verifier'' is used 
interchangeably to refer to both a ``verification body'' (i.e., a 
verification company or organization) and a ``verifier,'' which is 
an individual that is a principal or employee of a verification 
body.
---------------------------------------------------------------------------

    In addition, verifiers must have sufficient knowledge of the rate-
based emission trading program rules, technical expertise, and 
knowledge of auditing, accounting, and information management 
practices, in order to perform verifcation services related to the 
Clean Power Plan. Accredited verifiers must be independent. Accredited 
verifiers may not provide verification services for any eligible 
resource for which they have a financial, management, or other 
interest.\75\ Such relationships constitute a conflict of interest 
(COI). COI situations may also arise as a result of personal 
relationships among individuals representing an ERC provider and an 
accredited verifier. A verification report would not be

[[Page 65002]]

accepted as part of an eligibility application or M&V report where the 
accredited verification body or any individual verifier has a COI. 
Accredited verification bodies must have management protocols in place 
to identify and remedy any COI prior to provision of verification 
services. The proposed federal plan and model rule provide that failure 
of an accredited verifier to identify and adequately address any COI 
prior to provision of verification services is grounds for revocation 
of accreditation. The EPA would perform periodic reviews of accredited 
verifiers, to ensure that verifiers are maintaining necessary technical 
and professional qualifications and are meeting program requirements 
for provision of verification services. The EPA may recognize, in part, 
accreditation by an outside organization where such outside 
accreditation demonstrates that federal plan requirements are met.\76\ 
The EPA requests comment on the proposed necessary requirements for an 
independent verifier to perform verification services in connection 
with the federal plan, including those requirements specifically 
detailed in this section of the preamble and the related language in 
the proposed model rule, and including whether there are any 
requirements that are not included in this proposal that should be 
included in the final rule. We further request comment on the level of 
detail that we should include in the final model rule regarding all 
requirements for indepenent verifiers, and all aspects of verification.
---------------------------------------------------------------------------

    \75\ Accredited verification bodies and individual verifiers may 
not have any direct or indirect organizational or personal 
relationships with an ERC provider that would impact their 
impartiality in assessing the validity and accuracy of the 
information in an eligibility application or M&V report. In addition 
to this general requirement, the following specific requirements 
also apply. Accredited verifiers must have no direct or indirect 
financial interest in, or other financial relationships with, an ERC 
provider or any related program or project that seeks issuance of 
ERCs. Accredited verifiers must have no relationship with the 
implementer of a program or project that seeks the issuance of ERCs, 
or any related ERC provider, that would represent a COI. Accredited 
verifiers must have no role in the development and implementation of 
a program or project that seeks issuance of ERCs, beyond the 
provision of verification services. Accredited verifiers must not be 
compensated, directly or indirectly, in relation to the quantified 
and verified MWh in an M&V report or on the basis of program or 
project approval, ERC issuance, or the number of ERCs issued. 
Accredited verifiers may not hold ERCs, or other financial 
derivatives related to ERCs, or have a financial relationship with 
other parties that hold ERCs or other related financial derivatives. 
Verification reports must include an attestation by the accredited 
verifier that it assessed potential COI related to an ERC provider 
and adequately addressed any identified COI. The EPA requests 
comment the potential for payments to be channeled through the EPA 
as fees.
    \76\ An example is American National Standards Institute (ANSI) 
accreditation under ISO 14065:2013 for GHG validation and 
verification bodies. More information is available at https://www.ansica.org/wwwversion2/outside/GHGgeneral.asp.
---------------------------------------------------------------------------

8. Evaluation, Measurement, and Verification Plans, Monitoring and 
Verification Reports, and Verification Reports
    This section identifies and discusses the EM&V approaches used to 
quantify and verify MWh from RE, demand-side EE, and other eligible 
measures used to generate ERCs or otherwise adjust an emission 
rate.\77\
---------------------------------------------------------------------------

    \77\ EM&V is defined here as the set of procedures, methods, and 
analytic approaches used to quantify the MWh from RE, demand-side 
EE, and other eligible measures to ensure that the resulting savings 
and generation are quantifiable and verifiable. In this proposal, we 
are proposing EM&V for the eligible RE, and we request comment on 
EM&V for demand-side EE and any other measures that could be 
eligible.
---------------------------------------------------------------------------

    Only a subset of the potentially creditable ERC resources discussed 
in this section are actually being proposed as part of the federal 
plan. The remainder, and their associated requirements, are provided as 
part of the proposed model trading rule. Thus, all provisions of this 
subsection relating to such resources are presented only for the 
purpose of comment in the context of the federal plan, but are actually 
proposed for inclusion in the model trading rule. The ERC resources 
proposed in the federal plan must meet the following criteria: (1) They 
are in the following categories of measures: On-shore wind, solar, 
geothermal power, hydropower, or new nuclear units and capacity uprates 
at existing nuclear units; and (2) they can provide quantified 
generation data from a revenue quality meter. The language pertaining 
to all other measures (e.g., demand-side EE) is proposed only for the 
model rule. While they are currently being proposed as part of the 
model rule and not the federal plan, the EPA requests comment on the 
inclusion of other RE measures, demand-side EE measures, and any other 
measures that may be eligible under the final guidelines as eligible 
measures under the federal plan. For stakeholders that are submitting 
comments on the inclusion of such additional measures, the EPA requests 
comment on how the EPA could implement across applicable jurisdictions 
a rigorous, straightforward, and widely demonstrated set of EM&V 
methods, procedures, and approaches that could be implemented in the 
time frame allowed by the federal plan and that also meet the 
requirements outlined in the final guidelines. To the extent they are 
proposed for inclusion in the model trading rule, we also invite 
comment on these requirements in the context of state implementation as 
part of a state plan. Thus, commenters on this aspect of the proposal 
should consider whether and how these provisions could be implemented 
at the state level. Comments that suggest an approach not authorized by 
the EGs will likely be considered outside the scope of this proposed 
rule.
    Additionally, with respect to EM&V, the EPA describes certain 
established industry best-practice methods, procedures, and approaches 
that would be presumptively approvable if included in state plans. 
States wishing to adopt the model rule must submit these methods, 
procedures, and approaches as specified, or may submit alternative EM&V 
that is functionally equivalent to the industry best-practices 
described as presumptively approvable.\78\
---------------------------------------------------------------------------

    \78\ The EPA recognizes that EM&V is routinely evolving to 
reflect changes in markets, technologies and data availability, and 
expects to update its EM&V guidance over time. Therefore the agency 
expects that alternative quantification approaches will emerge that 
can be approved for use, provided that such approaches are 
functionally equivalent to the provisions for EM&V outlined in this 
section.
---------------------------------------------------------------------------

    As discussed in section IV.C.3 of this preamble, quantified and 
verified MWh of RE generation and other means of generating ERCs may be 
used to adjust a CO2 emission rate when demonstrating 
compliance with the EGs. Providers other than affected EGUs who seek to 
earn ERCs must develop EM&V plans outlining how they will quantify and 
verify the resulting MWh from their efforts. These providers must then 
submit these EM&V plans as part of their application to the 
Administrator for project approval.\79\
---------------------------------------------------------------------------

    \79\ A full discussion of applicable requirements for the 
establishment and functioning of the rate-based trading system is 
provided above, in section IV.D of this preamble.
---------------------------------------------------------------------------

    a. Overall Approach and Measure-Specific Requirements. The proposed 
Clean Power Plan stated that the EPA would establish EM&V requirements 
and procedures to help states, sources, and resource providers quantify 
and verify MWh savings and generation resulting from zero-emitting RE 
and demand-side EE efforts. This action proposes those requirements 
that the EPA committed to establish. The Clean Power Plan proposal and 
associated ``State Plans Considerations'' TSD \80\ suggested that such 
EM&V requirements would leverage existing industry practices, 
protocols, and tracking mechanisms currently utilized by the majority 
of states implementing RE and demand-side EE. The EPA further noted 
that many state regulatory bodies and other entities already have 
significant EM&V infrastructure in place and have been applying, 
refining, and enhancing their evaluation and quality assurance 
approaches for over 30 years, particularly with regard to the 
quantification and verification of energy savings resulting from 
utility-administered EE programs. The EPA also observed that the 
majority of RE generation is typically quantified and verified using 
readily available, reliable, and transparent methods such as direct 
metering of MWh. The EPA is proposing EM&V methods, procedures, and 
approaches, described herein, that are intended to be consistent with 
and leverage prevailing industry best-practices.
---------------------------------------------------------------------------

    \80\ See discussion beginning on p. 34 of the State Plan 
Considerations TSD for the Clean Power Plan Proposed Rule: http://www2.epa.gov/carbon-pollution-standards/clean-power-plan-proposed-rule-state-plan-considerations.
---------------------------------------------------------------------------

    In addition, the EPA's proposed EM&V methods, procedures, and

[[Page 65003]]

approaches reflect several overarching objectives and principles 
offered by states, private organizations, and the public during the 
comment period of the Clean Power Plan EGs. One of these is the 
importance of balancing the accuracy and reliability of results with 
the associated costs of EM&V. Another objective for the EPA's proposed 
EM&V is to avoid excessive interference with existing practices that 
are already robust, transparent and effective.
    Submittals. Applicable submittals under a rate-based emission 
trading program include eligibility applications (including EM&V 
plans), monitoring and verification reports, and verification reports. 
These submittals are described in section VIII.K.3.b of the final EGs 
preamble and in this model rule and federal plan. At the initiation of 
a program or project, ERC providers develop and submit to the state or 
the EPA, respectively, an EM&V plan that documents how requirements for 
quantification and verification will be addressed as EM&V is performed 
over the program or project period. After implementation has occurred, 
the ERC provider must submit periodic M&V reports to document and 
describe how each of the requirements were applied. These reports must 
also specify the resulting MWh savings or generation values, as 
determined on a retrospective (ex-post) or real-time basis. MWh values 
may not be determined using projections or other ex-ante quantification 
approaches.
    Each EM&V plan submitted in support of an eligibility application 
must identify the eligible resource covered by the plan, and provide 
specific EM&V criteria that specify the manner in which the energy 
generated or saved by the eligible resource will be quantified, 
monitored and verified. The manner of quantification, monitoring and 
verification must meet the criteria outlined below and included in the 
proposed model rule, as applicable to the specific eligible resource. 
We request broad comment on each criteria specified below and in the 
proposed model rule, for each eligible resource. Specifically, we seek 
comment on the substantive content of the criteria, and we seek comment 
on the level of detail provided and whether more or less detail (and 
what detail) should be included in the final model rule, and whether 
the criteria should differ for each eligible resource.
    Each M&V report submitted in support of the issuance of ERCs to a 
specific eligible resource must include specific criteria described 
here and in the proposed model rule. For the first M&V report 
submitted, a key component is documentation that the electricity-
generating resources or electricity-saving measures were installed or 
implemented consistent with the description in the approved eligibility 
application. Each following M&V report must then identify the time 
period covered by the M&V report, describe how the methods specified in 
the EM&V plan were applied during the reporting period, and document 
the quantity (in MWh) of energy generation and/or electricity savings 
quantified and verified for the period covered by the M&V report. Any 
change in the energy generation or savings capability of the eligible 
resource during the period covered by the M&V report must also be 
included in the M&V report, along with the date on which the change 
occurred, and information sufficient to demonstrate whether the 
eligible resource continued to meet all eligibility requirements during 
the period covered by the M&V report. Any change should also be 
specified in the report. The EPA requests broad comment on each of 
these criteria, as described here and in the proposed model rule. 
Specifically, we seek comment on the substantive content of the 
criteria, and we seek comment on the level of detail provided and 
whether more or less detail (and what detail) should be included in the 
final model rule, and whether the criteria should differ for each 
eligible resource.
    Each verification report submitted by an independent verifier in 
support of the issuance of ERCs to a specific eligible resource must 
address the criteria described here and in the proposed rule text. Each 
verification report must set forth the findings of the verifier, based 
on an assessment of all relevant requirements, information and data, 
including an assessment of any material misstatements or data 
discrepancies. Any verification report included as part of an 
eligibility application must further describe the review conducted by 
the verifier and verify the following: The eligibility of the resource 
to be issued ERCs; that the eligible resource exists and has been, or 
will be, generating energy or saving electricity in the manner 
required; that the EM&V plan meets its requirements; and any other 
information required or that the verifier finds, in its professional 
opinion, is necessary to assess the accuracy of the subject of the 
verification report. Each verification report included as part of a M&V 
report must also describe the review conducted by the verifier and 
verify the following: The adequacy and validity of the information and 
data submitted to quantify eligible MWh of electric generation or 
electricity savings during the period covered by the report, as well as 
all supporting information and data identified in the EM&V plan and M&V 
report; evaluate whether all generation or savings data are within a 
technically feasible range for that specific eligible resource 
(determined through a quality assurance and quality control check of 
the data); that the M&V report meets its requirements; and any other 
information required or that the verifier finds, in its professional 
opinion, is necessary to assess the accuracy of the subject of the 
verification report. The EPA requests broad comment on each of these 
criteria, as described here and in the proposed model rule. 
Specifically, we seek comment on the substantive content of the 
criteria, and we seek comment on the level of detail provided and 
whether more or less detail (and what detail) should be included in the 
final model rule, and whether the criteria should differ for each 
eligible resource.
    For demand-side EE, all EM&V plans that are developed for purposes 
of adjusting an emission rate under this proposed rule are intended to 
leverage and closely resemble the plans already in routine use for a 
wide range of publicly or rate-payer funded EE programs and energy 
service company (ESCO) projects. For RE, EM&V plans similarly leverage 
resources and approaches to MWh tracking for RE that are broadly 
applied in the state and regions. The existing reports and 
documentation from existing tracking systems may serve as the 
substantive basis for a monitoring and verification report for RE.
    b. Renewable Energy EM&V Requirements. This section describes the 
EM&V requirements associated with quantifying electricity generation 
from eligible RE and nuclear energy, and for documenting these 
requirements in EM&V plans and reports. Consistent with prevailing 
views expressed in public comments, the EPA's requirements presume that 
the quantification of RE generation can leverage the infrastructure and 
documentation associated with the establishment of renewable energy 
certificates (RECs) and registration of such certificates in REC 
registries. These registries typically include well-established 
safeguards, documentation requirements, and procedures for registry 
operations intended to support the demonstration of compliance with 
state RPS policies. A key element of RPS compliance is that each RE 
generating unit must be uniquely identified and recorded in a registry 
to avoid the double counting of RECs.

[[Page 65004]]

    The primary metric for all RE is electricity generation, in units 
of MWh. Measured output must be derived either from: (1) A revenue 
quality meter that meets the applicable ANSI C-12 standard or 
equivalent, which is the typical requirement for settlements with RTO 
and other control-area operators; or (2) For customer-sited generators 
that are interconnected behind the customer meter, measurement at the 
AC output of an inverter, adjusted to reflect the energy delivered into 
either the transmission or distribution grid at the generator bus bar. 
Further, a RE generating facility of 10 Kilowatt capacity or less may 
estimate the facility's output if the state where it is located 
explicitly allows estimates to be used and provides rules for when it 
will be allowed. In the latter case, calculations of system output must 
be based on the RE unit's capacity, estimated capacity factors, and an 
assessment of the local conditions that affect generation levels. All 
such input parameters and assumptions must be clearly described and 
documented. For RE units that are managed by regional transmission 
operators or other control area operators, metered generation data 
should be electronically collected by the control area's energy 
management system, verified through an energy accounting or settlements 
process, and reported by the control area operator to the REC registry 
at least monthly. The EPA requests comment on this proposed requirement 
for quantifying RE generation for the purpose of ERC issuance.
    For RE units that do not go through a control area settlements 
process, metered data may be read and transmitted to the ERC registry 
by an independent third party, or may be self-reported. Third-party and 
self-reported generation data must be reported on an annual basis. All 
such data must be verified for reasonableness by the agency, the state, 
or the REC registry.
    For reporting purposes, RE generation may be aggregated from 
multiple generators into a single MWh value for the group, provided the 
following requirements are met: Each RE unit is uniquely identified in 
the federal tracking system, the nameplate capacity of each RE unit is 
less than 150 Kilowatt, the aggregated RE units collectively have 
nameplate generating capacities less than 1.0 MW, the units aggregated 
are located in the same state, the RE units being aggregated utilize 
the same technology/fuel type, and the RE unit's generation data are 
based on the same metering or the same generation estimating software 
or algorithms. The EPA requests comment on how existing reporting 
systems can play a role in meeting EM&V requirements under the federal 
plan and model rule, particularly, in assuring that each MWh of RE 
generation is uniquely identified and recorded to avoid double 
counting.
    An additional consideration regarding distributed RE units that 
directly serve on-site end-use electricity loads is that avoided 
transmission and distribution (T&D) system losses can be quantified, as 
is commonly practiced with demand-side EE. If such T&D losses are 
quantified, the requirements for demand-side EE would be applicable.
    The EPA requests comment on all metering, measurement, 
verification, and other requirements proposed in this subsection, 
including the appropriateness of their use for each type of RE resource 
(including the relevant size and distribution of such resource) that 
qualifies for issuance of ERCs for use for compliance.
    For RE resources with a nameplate capacity of 10 Kilowatt or more 
and for RE resources with a nameplate capacity of less than 10 Kilowatt 
for which metered data are available, we request comment on the 
appropriateness of the requirement to use a revenue quality meter for 
monitoring generation, and we request comment on the definition of 
revenue quality meter. We request comment on the appropriateness of 
other types of meters for monitoring generation. We request comment on 
whether 10 Kilowatt is the appropriate threshold, under which an 
eligible resource can be issued ERCs for generation based on data other 
than metered generation, and if not, what would be the appropriate 
threshold.
    For RE resources of all sizes and means of monitoring, we request 
comment on the appropriate requirements for allowing generation data to 
be aggregated, including comment on the provisions in the proposed 
model rule and any alternatives to them. We request comment on whether 
all of the generating units have the same essential generation 
characteristics, in order for their data to be aggregated, and if so, 
what is the appropriate definition of ``essential generation 
characteristics'' (e.g., are essential generating characteristics 
determined on a resource by resource basis, or can generation from a 
group of wind turbines be aggregated with generation from a group of 
solar panels?) We seek comment on the appropriate thresholds for the 
aggregated of individual units (e.g., nameplate capacity of less than 
150 Kilowatt per unit and the units collectively do not exceed a total 
nameplate capacity of 1 MW when aggregated, as in the proposed model 
rule).
    For non-metered units of less than 10 Kilowatt, we request comment 
on whether the final model rule should specify the specific estimating 
software or algorithms by which generation data should be measured, and 
if so, we request broad comment on the appropriate estimating software 
or algorithms and the appropriate characteristics for such estimating 
software or algorithms.
    We request comment on any other requirements that should be 
included in the final model rule regarding EM&V of RE resources.
    For all energy generating resources (such as RE, but also including 
applicable resources requiring EM&V described below), we request 
comment on the appropriate place of measurement of the generation, 
including comment on whether measurement should be at the bus bar or at 
a different location (or in the case of meters on units of less than 10 
Kilowatt, at the AC output of the inverter or elsewhere), whether 
measurement should be before or after parasitic load (and how to 
separate out parasitic load). In addition, for all energy generating 
resources, we request comment on whether generation data should go 
through a control area settlement process prior to issuance of ERCs, 
and if so, what level of specificity with respect to that process we 
should include in the final model rule. If not, or if the unit does not 
go through a control area settlement process, we request comment on how 
the data collection should be specified in the final model rule. 
Finally, we request comment on the frequency with which data should be 
collected, for all energy generating resources, of all sizes.
    c. Nuclear EM&V Requirements. The EM&V requirements associated with 
quantifying electricity generation from eligible nuclear energy 
resources, and for documenting these requirements in EM&V plans and 
reports are the same as the requirements for RE discussed in the 
preceding subsection.
    The EPA requests comment on all metering, measurement, 
verification, and other requirements in this subsection, including the 
appropriateness of their use for each type of nuclear energy resource 
(including the relevant size and distribution of such resource) that 
qualifies for issuance of ERCs for use in Clean Power Plan compliance. 
We request comment on whether nuclear energy resources should be 
subject to the same EM&V requirements as RE resources, and if not, we 
request

[[Page 65005]]

comment on to which EM&V requirements nuclear energy resources should 
be subject.
    d. Non-Affected Combined Heat and Power EM&V Requirements. In 
additon to the CHP specific EM&V requirements discussed below and in 
the associated provisions in the model rule, all CHP must follow the 
requirements for RE discussed in the preceding subsection, including 
metering requirements, special treatment for units of less than 10 
Kilowatt, and how to account for T&D losses.
    In order to determine the incremental CO2 emission rate, 
a CHP unit would monitor CO2 emissions and energy 
output.\81\ The monitoring requirements are standard methods currently 
in use and the requirements would depend on the size of the CHP units 
and the fuel used in the unit.
---------------------------------------------------------------------------

    \81\ When a CHP unit uses biomass fuel, it must report both 
total CO2 emissions and biogenic CO2 
emissions. Proposed requirements for reporting biogenic 
CO2 emissions are discussed below in the subsection 
titled Biomass EM&V requirements.
---------------------------------------------------------------------------

    Non-affected CHP facilities \82\ with electric generating capacity 
greater than 25 MW would follow the same monitoring and reporting 
protocols for CO2 emissions and energy output as are 
required for affected EGU CHP units. These requirements are discussed 
in section IV.D.13 of this preamble. For non-affected CHP facilities 
with electric generating capacity less than or equal to 25 MW, which 
use only natural gas and/or distillate fuel oil, the low mass emission 
unit CO2 emission monitoring and reporting methodology 
outlined in 40 CFR part 75 is acceptable.
---------------------------------------------------------------------------

    \82\ A CHP facility may consist of one or more electric 
generators.
---------------------------------------------------------------------------

    The EPA requests comment on all metering, measurement, 
verification, and other requirements included in this subsection with 
respect to CHP, including the appropriateness of their use for CHP 
(including with respect to the size of the CHP resource). We request 
comment on whether a CHP unit should be subject to the same EM&V 
requirements as RE resources, and we request comment on any additional 
EM&V requirements to which CHP units should be subject. Specifically, 
we request comment on specifying in the final model rule that if a CHP 
unit has an electric generating capacity greater than 25 MW, its EM&V 
plan must specify that it will meet the requirements that apply to an 
affected EGU under 40 CFR 62.16540. We also request comment on 
specifying in the final model rule that if a CHP unit has an electric 
generating capacity less than or equal to 25 MW, the EM&V plan must 
specify that it will meet the low mass emission unit CO2 
emission monitoring and reporting methodology in 40 CFR part 75. We 
request comment on any alternatives to these measurement methodologies 
that should be specified in the final model rule. We request comment on 
any other requirements that should be included in the final model rule 
regarding EM&V of CHP.
    e. Biomass EM&V Requirements. A state plan that is adopting the 
rate-based model rule must propose EM&V requirements for monitoring and 
reporting biogenic CO2 emissions from the use of qualified 
biomass at RE facilities that are eligible for adjusting a 
CO2 emission rate. If a state proposes to use the monitoring 
and reporting requirements for biogenic CO2 emissions in 40 
CFR part 98 (40 CFR 98.3(c), 98.36(b)-(d), 98.43(b), and 98.46) in its 
plan submission, those requirements are presumptively approvable. An 
EM&V plan that addresses biomass RE must follow the requirements for 
monitoring and reporting biogenic CO2 emissions from the 
facility that were approved by the EPA in connection with the specific 
state plan.
    The EPA requests comment on all metering, measurement, 
verification, and other requirements included in this subsection with 
respect to biomass, including the appropriateness of their use for 
qualified biomass. We request broad comment on the types of qualified 
biomass feedstocks that should be specified in the final model rule, if 
any. We request comment on the methods that we should specify in the 
final model rule for the measurement of the associated biogenic 
CO2 for such feedstocks, as well as what other requirements 
we should specify in the final model rule related to qualfied biomass. 
We request comment on any other requirements that should be included in 
the final model rule regarding EM&V for qualified biomass. Detailed 
discussion on the role of qualified biomass feedstocks can be found in 
section IV.C.3 of this preamble.
    f. Waste-to-Energy EM&V Requirements. A state plan that is adopting 
the rate-based model rule must propose EM&V requirements for monitoring 
and reporting biogenic CO2 emissions from waste-to-energy 
facilities that are eligible for adjusting a CO2 emission 
rate. If a state proposes to include the monitoring and reporting 
requirements for biogenic CO2 emissions in 40 CFR part 98 
(40 CFR 98.3(c), 98.36(b)-(d), 98.43(b), and 98.46) in its plan 
submission, those requirements are presumptively approvable. The EPA 
may approve other requirements of similar rigor, at its discretion. An 
EM&V plan that addresses the biogenic CO2 emissions from a 
waste-to-energy facility must follow the requirements for monitoring 
and reporting biogenic CO2 emissions from the facility that 
were approved by the EPA in connection with the specific state plan.
    As discussed in the final EGs (see section VIII.K.1 of the final 
EGs), only the portion of electric generation at a waste-to-energy 
facility that is due to the biogenic content of the MSW may be used to 
generate ERCs or counted by a state towards its achievement of its 
obligations pursuant to this regulation.
    The EPA requests comment on all metering, measurement, 
verification, and other requirements included in this subsection with 
respect to waste-to-energy, including the appropriateness of their use 
for waste-to-energy. We request comment on whether a waste-to-energy 
resource should be subject to the same EM&V as RE resources, and we 
request comment on any additional EM&V requirements to which waste-to-
energy resources should be subject, including comment on any specific 
methods for determining the specific portion of the total net energy 
output from the resource that is related to the biogenic portion of the 
waste that the EPA should include in the final model rule.
    g. Demand-Side Energy Efficiency EM&V Provisions. This subsection 
proposes EM&V provisions that will be presumptively approvable if 
included in state regulations governing how EE is to be quantified by 
EE providers and verified by independent entities acting on behalf of 
the state. As noted above these proposed provisions apply to all 
demand-side EE used to adjust an emission rate if a state adopts the 
model rule. The EPA is soliciting comment on the incorporation of EE 
for the federal plan and by extension the EM&V associated with it.
    For all demand-side EE used to generate ERCs, the EPA is proposing 
that the metric is MWh of electricity savings, which must be quantified 
on an ex-post or real-time basis and defined as a reduction in 
facility- or premises-level electricity consumption due to an EE 
program, project, or measure.
(1) Common Practice Baseline
    Based on public input and assessments of industry best-practice 
protocols and procedures, the EPA is proposing that it is presumptively 
approvable to quantify EE savings as the difference between actual 
metered electricity usage after an EE program, project, or measure is 
implemented, and a ``common practice baseline'' (CPB). A

[[Page 65006]]

CPB is the equipment that would most frequently be installed at the 
time an existing piece of equipment fails or is replaced at the end of 
its effective useful life--or that a typical consumer or building owner 
would have continued using for the remainder of the equipment's 
effective useful life--in a given circumstance (i.e., a given building 
type, EE program type or delivery mechanism, and geographic region) at 
the time of EE implementation. It defines what would commonly have 
happened in the absence of the EE program, project, or measure.
    The applicable CPB depends on a number of factors, such as 
characteristics of the EE program, project, or measure, the mechanism 
by which electricity customers are engaged, local consumer and market 
characteristics, and the applicable building energy codes and product 
standards (C&S), including the C&S compliance rate. Examples of 
appropriate CPBs to apply in specific circumstances, which may be 
presumptively approvable, can be found in the EPA's EM&V guidance. EE 
providers must document the selected CPB in their EM&V plans, along 
with clear documentation and discussion of the rationale, 
applicability, and relevant data sources, protocols, and other 
supporting information. Monitoring and verification reports must refer 
to the EM&V plan and confirm that the CPB was appropriately applied.
(2) Methods Used To Quantify Savings From Energy Efficiency Programs 
and Projects
    This section proposes criteria that are presumptively approvable 
for the general types of EM&V methods that EE providers may use to 
quantify the MWh savings from demand-side EE programs, projects, and 
measures. During the Clean Power Plan EG's public comment period, the 
EPA received input indicating that state PUCs typically allow utilities 
and other EE providers to use a range of EM&V methods that reflect 
applicable circumstances and on-the-ground conditions (versus mandating 
which methods must be used in a particular situation). Consistent with 
this approach, the EPA is proposing to offer flexibility for EE 
providers to select from three broad categories of EM&V methods to 
determine savings.
    These categories include project-based M&V, deemed savings, and 
comparison group approaches such as randomized control trials (RCT). 
Regardless of the approach selected, the EPA is proposing that annual 
savings values must be quantified using these EM&V methods at specified 
time intervals (in years) on a recurring basis over the effective 
useful life of the EE project or measure in order to ensure accurate 
and reliable savings values. To be presumptivey approable, the EPA is 
proposing that EE providers must apply the above methods at a minimum 
of 4-year intervals for building energy codes and product standards; 
every 1, 2, or 3 years for publicly- or utility-administered EE 
programs, depending on the program type, magnitude of savings, and 
experience with the program; and annually for large individual 
commercial and industrial projects, unless the EE provider can credibly 
demonstrate why this is not possible and how the accuracy and 
reliability of savings values will be maintained. The EPA is further 
proposing that, to be presumptively approvable, the selected method, 
associated assumptions, and data sources must be identified and 
described in EM&V plans.
    For comparison group approaches, the EPA is propsing that states 
and EE providers can refer to the EPA's draft EM&V guidance for a 
discussion of industry best-practice protocols and guidelines. Where 
feasible, the EPA is proposing to encourage the use of RCT methods, 
which determine savings on the basis of energy consumption differences 
between a treatment group and a comparison group, and therefore 
increase the reliability of results.
    As noted above, an alternative to comparison group methods is the 
use of deemed savings values, which establish pre-determined annual 
electricity savings values for specific EE measures. The EPA is 
proposing that the use of deemed savings values would be presumptively 
approvable if those values (a) are documented in a publicly available 
database (also known as a Technical Reference Manual (TRM)) that is 
accessible on a public Web site, or is otherwise readily accessible; 
(b) specify the conditions for which each deemed value can be applied, 
including but not limited to climate zone, building type, and EE 
implementation mechanism; and (c) are updated at a minimum of every 3 
years to reflect the per-measure MWh savings documented in ex-post EM&V 
studies that apply M&V or comparison group methods.
    For M&V methods to be presumptively approvable, the EPA is 
proposing is that industry best-practice protocols and/or guidelines 
must be followed. Examples of acceptable best-practice protocols and 
guidelines are provided in the EPA's EM&V guidance. EE providers can 
consult the EM&V guidance to assess the applicability of these 
technical resources to the EE programs and projects generating savings, 
and must document how one or more best-practice protocols or guidelines 
will be appropriately applied in EM&V plans (along with clear 
documentation and discussion of the rationale, applicability, and 
relevant data sources, and other supporting information). The EPA is 
also proposing that monitoring and verification reports must refer to 
the EM&V plan and confirm that the relevant M&V protocol or guideline 
was properly applied.
(3) Quantifying Savings
    Regardless of the approach used to quantify and verify MWh savings, 
the EPA is proposing that EM&V plans must describe how they will 
address the following provisions:
     How major changes in independent variable conditions 
(weather, occupancy, production rates, etc.) that affect energy 
consumption and savings estimates will be accounted for. The EPA is 
proposing that the effects of these changes must be calculated using 
industry best-practices such as real-time conditions or normalized 
conditions that are reasonably expected to occur throughout the 
lifetime of the EE project or measure.
     How the initial installation of EE will be verified for EE 
program categories that involve the installation of identifiable 
measures (e.g., most utility consumer-funded EE programs and project-
based EE are evaluated site-by-site). The EPA is proposing that 
verification is required within the first year of program 
implementation and that all verification activities must be performed 
using industry best-practice techniques (e.g., phone or mail surveys, 
document review, site inspections, spot or short-term metering). For 
projects implemented as part of a larger program, the EPA is proposing 
that verification can be performed using a sample of projects to 
represent the full program population.
     How avoided T&D system losses \83\ will be quantified and 
applied to EE savings determined at the customer facility or premises. 
The EPA is proposing that demand-side EE programs (other than T&D 
efficiency measures such as conservation voltage regulation or 
reduction (CVR) and volt/VAR optimization \84\) may adjust

[[Page 65007]]

reported savings by using a T&D adder. If such an adder is applied, the 
presumptively approvable approach is to use the smaller of 6 percent or 
the calculated statewide annual average T&D loss rate (expressed as a 
percentage) calculated using the most recent data published by the U.S. 
EIA State Electricity Profile.\85\
---------------------------------------------------------------------------

    \83\ T&D losses are defined as the difference between the 
quantified EGU generation required to serve a customer's load 
(measured at the EGU bus bar) and the customer's actual electricity 
consumption (measured at the customer meter).
    \84\ More information about these technologies is in section 
VIII.F.1 of the final EGs.
    \85\ Estimated losses in MWh, total electric supply, and direct 
electricity use values are available in the U.S. EIA's State 
Electricity Profiles. See Table 10 on Supply and Disposition of 
Electricity. Direct electricity use refers to the electricity 
generated at facilities that is not put onto the electricity grid, 
and therefore does not contribute to T&D losses.
---------------------------------------------------------------------------

     How the duration of EE program or project electricity 
savings will be determined. This must be determined using industry 
best-practice protocols and procedures involving annual verification 
assessments, industry-standard persistence studies, deemed estimates of 
effective useful life (EUL), or a combination of all three.
     How the accuracy and reliability of quantifying MWh 
savings values will be assessed, and the rigor \86\ of the methods used 
to control the types of bias or error inherent to the applied EM&V 
methods. Sampling of populations is appropriate, provided that the 
quantified MWh derived from sampling have at least 90 percent 
confidence intervals whose end points are no more than +/-10 percent of 
the estimate.
---------------------------------------------------------------------------

    \86\ Rigor refers to the level of effort expended to minimize 
uncertainty from factors such as sampling error and bias. The higher 
the level of rigor, the more confident one is that the results of 
the EM&V activities are both accurate and precise.
---------------------------------------------------------------------------

     How double counting will be avoided through the use of 
tracking and accounting procedures to ensure that the same MWh of 
electricity savings is not claimed more than one time (for example, two 
EGUs claiming savings from the same lighting retrofit). The types of 
double counting that may arise are discussed in the EPA's draft EM&V 
guidance.
(4) Use of Energy Efficiency EM&V Protocols
    In the Clean Power Plan EG's public comments, the EPA heard that 
EM&V protocols for demand-side EE are currently in wide use, and that 
they should be continued and encouraged. The agency agrees with this 
observation and is therefore proposing the application of industry 
best-practice protocols and procedures for demand-side EE. In 
particular, the EPA is proposing that, to be presumptively approvable, 
EM&V plans must specify the use of best-practice protocols and 
procedures, and must also include a clear description and documentation 
of how the relevant protocols and procedures will be applied. EM&V 
reports must include documentation of how such protocols and procedures 
were actually applied. EE providers can refer to the EPA's EM&V 
guidance document for information about protocols that are considered 
``industry best-practice protocols and procedures.''
(5) Eligible Demand-Side Energy Efficiency (DS-EE) Programs and 
Projects
    There has been stakeholder interest expressed through the Clean 
Power Plan EGs rulemaking process in allowing states to issue ERCs for 
quantified and verified MWh savings from DS-EE under state plans. 
Consistent with these perspectives, the EPA is proposing that any 
demand-side EE program, project, or measure that results in MWh savings 
may be potentially eligible to generate ERCs, including under this 
proposed model trading rule, provided that they meet the presumptively 
approvable provisions for eligibility described in section IV.C.3 of 
this preamble, and that supporting EM&V is rigorous, transparent, 
credible, complete and fulfills the requirements provided in the EGs 
and the state plan. Examples of potentially eligible demand-side EE 
program and project types include:
     Publicly or utility-administered EE programs, including 
those implemented in low-income residences and facilities.
     Project-based EE evaluated site-by-site, for example those 
implemented by ESCOs at commercial buildings and industrial facilities.
     State and local government building energy code and 
compliance programs.
     State and local government incremental product energy 
standards.
    The EPA's EM&V guidance contains supplemental information about 
applicable best-practice protocols, methods, and other key 
considerations for quantifying and verifying savings from the above-
listed EE activities in an accurate and reliable manner. The agency 
also recognizes that the programs and policies listed above will evolve 
and change over the rule period, as new technologies emerge and 
efficiency improves. The agency also expects that new EE program types 
will emerge and expand throughout the rule period, and that MWh savings 
resulting from any such programs can similarly be considered if they 
meet the requirements of the EGs.
(6) Requests for Comment on Energy Efficiency EM&V
    We request broad comment on each EE EM&V criterion described herein 
and in the proposed rule text, for each type of EE activity, project, 
program, or measure. Specifically, we seek comment on the substantive 
content of the criteria, and we seek comment on the level of detail 
provided regarding these criteria and whether more or less detail (and 
what detail) should be included in the final model rule. In addition, 
we seek comment on whether some of the EE EM&V criteria (and if so, 
which criteria) included in the draft guidance document released 
simultaneously with this proposed rulemaking should instead be included 
in the final model rule, instead of in guidance. Similarly, we seek 
comment on whether some of the EE EM&V criteria (and if so, which 
criteria) included in the proposed model rule should instead be 
addressed in the final EM&V guidance. More generally, we seek comment 
on what EE criteria the EPA should described in guidance versus what 
criteria the EPA should specify in the final model rule, whether or not 
those criteria are already included in the draft guidance or proposed 
model rule.
    We request broad comment on the appropriate EE EM&V criteria for 
quantifying the electricity savings from every type of EE program, 
project, or measure. We request broad comment on what constitute EE 
best-practice protocols and procedures for every type of EE program, 
project, or measure.
    We request broad comment on whether, when, and how common practice 
baselines should and should not be used in calculating electricity 
savings from EE activities, projects, programs, and measures, including 
comment on which common practice baselines should be used in which 
circumstances. We also request comment on whether some alternative 
metric should be used in lieu of the common practice baseline and, if 
so, what that metric should be.
    We request broad comment on the appropriateness of quantifying 
electricity savings by applying one or more of the following methods 
and comment on all aspects of each method: Project-based measurement 
and verification (PB-MV), comparison group approaches, or deemed 
savings. We take further comment on circumstances in which it is 
appropriate (or inappropriate) to use each of these methods, including 
when it is appropriate to use RCT and quasi-experimental methods, and 
the circumstances in which they can be encouraged and applied in 
practice (e.g., when a suitable control or comparison group can be 
identified and applied in a cost-effective manner). In addition, we 
request comment on whether the general suitability and applicaton of 
quantification methods, such as RCT,

[[Page 65008]]

quasi-experimental techniques or other comparison group approaches when 
they are available at reasonable cost for purposes of quantifying MWh 
savings for particular EE programs, projects, or measures.
    If deemed savings are to be used in quantifying electricity savings 
from an EE program, project, or measure, we request comment on the 
appropriate characteristics and presumptively approvable provisions for 
their use in generating qualifying ERCs, including the basis and 
frequency for their determination, and the appropriateness of their 
application to particular EE programs, projects or measures in 
particular states or regions. We further request comment on the 
presumptively approvable provision for public access and input to the 
development of the technical reference manuals (TRMs) used to house the 
applicable deemed savings values.
    We request comment on the minimum and maximum intervals (in years) 
over which electricity savings must be quantified, including those time 
intervals specified in the proposed model rule, and we request comment 
on any factors that must be taken into consideration when determining 
the appropriate time interval for specific EE programs, projects, or 
measures.
    Because many states have different EE programs in place today, and 
we would expect them to leverage these programs if they incorporated EE 
into a rate-based trading scheme with ERCs, it is theoretically 
possible that an ERC could be issued in one state that would not have 
been issued in another, even if both states have rate-based programs in 
place that meet all of the EGs. The EPA requests comment on what 
criteria it should include in the final model rule, and what level of 
details with respect to those criteria that it should include, in order 
to ensure that an ERC issued for an EE program, project, or measure in 
one state reflects the same MWh of energy or electricity saved in 
another state. We further request comment on whether there are 
provisions that the EPA should include in the final model rule that 
would prevent an entity seeking to be issued an ERC (whether from EE or 
energy generation) from forum shopping, in an effort to find a state 
with standards for ERC issuance that it deems more lenient or less 
burdensome than those in another state.
    We request comment on how to appropriately consider factors that 
affect energy savings in the quantification and verification process, 
including those identified in the proposed model rule, and we request 
comment on whether these factors should be addressed in every plan or 
just certain types of plans. Such factors may include the effect of 
changes in independent factors, effective useful life (and its basis), 
and interactive effects of EE programs, projects, and measures.
    We request comment on the circumstances and frequency in which 
savings verification must occur to ensure that EE measures have been 
installed, are functioning, and have the potential to save energy.
    We request comment on the appropriate steps for avoiding double 
counting, and how such steps should be documented in an EM&V plan. In 
particular, we request comment on the circumstances and conditions in 
which double counting is most likely to occur (including those 
identified in this section), and the presumptively approvable 
provisions that must be adopted in state plans for avoiding and 
mitigating double counting.
    We request comment on the appropriate means by which an EM&V plan 
can ensure the accuracy and reliability of electricity savings 
estimates, including the necessary rigor of the methods selected to 
evaluate the electricity savings, the methods used to control all 
relevant types of bias and to minimize the potential for systematic and 
random error, and the potential effects of such bias and error. We 
further request comment on the presumptively approvable provision that 
samples taken to quantify EE program savings must achieve 90/10 
confidence and precision.
    We request comment on the presumptively approvable approach to 
quantifying the electricity savings that result from avoiding a 
transmission and distribution system loss, including the provisions in 
the proposed model rule, which specify that each EM&V plan must 
quantify the transmission and distribution loss based on the lesser of 
6 percent of the site-level electricity consumption measured at the end 
use meter or the statewide annual average transmission and distribution 
loss rate (expressed as a percentage) from the most recent year that is 
published in the U.S. EIA State Electricity Profile. We request comment 
on the appropriateness of including a restriction in the final model 
rule that no other transmission and distribution loss factors may be 
used in calculating the electricity savings.
    We request comment on any additional criteria that we should 
include in the final model rule regarding EE EM&V.
    h. Skill Certification Standards. Using a skilled workforce to 
implement demand-side EE and RE projects and other measures intended to 
reduce CO2 emissions, and to evaluate, measure and verify 
the savings associated with EE projects or the additional generation 
from performance improvements at existing EGU's are both important. 
Several commenters on the EGs pointed out that skill certification 
standards can help to assure quality and credibility of demand-side EE, 
RE, and other carbon emission reduction projects. The EPA also 
recognizes that a skilled workforce performing the EM&V is important to 
substantiate the authenticity of emission reductions.
    The EPA agrees that in conjunction with other EM&V measures 
discussed in this section, and in the context of the model trading 
rules although this is not an aspect needed for presumptive 
approvability, states are encouraged to include in their plan a 
description of how states will ensure that workers installing demand 
side EE and RE projects, or other measures intended to reduce 
CO2 emissions, as well as workers who perform the EM&V of 
demand side EE and existing EGU performance will be certified by a 
third party entity that:
     Develops a training or competency based program aligned 
with a job task analysis and/or certification scheme;
     Engages with subject matter experts in the development of 
the job task analysis and/or certification schemes that represent 
appropriate qualifications, categories of the jobs, and levels of 
experience;
     Has clearly documented the process used to develop the job 
task analysis and/or certification schemes, covering such elements as 
the job description, knowledge, skills, and abilities;
     Has pursued third-party accreditation aligned with 
consensus-based standards, for example ISO/IEC 17024 or IREC 14732.
    Examples of such entities include: Parties aligned with the DOE's 
Better Building Workforce Guidelines and validated by a third party 
accrediting body recognized by DOE; or parties aligned with an 
apprenticeship program that is registered with the federal DOL, Office 
of Apprenticeship; or parties aligned with a state apprenticeship 
program approved by the DOL, or by another skill certification 
validated by a third party accrediting body. Entities such as these can 
help to substantiate the authenticity of emission reductions due to 
demand-side EE and RE and other carbon emission reduction measures.
9. ERC Transfers and Trading
    All affected EGUs that may be subject to this proposed federal plan 
would be required to be a part of the ATCS that

[[Page 65009]]

the EPA runs, although the affected EGUs that are regulated under the 
rate-based federal plan would use ERCs as a compliance instrument, not 
allowances. To register to participate in the ATCS an affected EGU must 
submit designated representative information. More information on the 
designated representatives is described above in section IV.D.1 of this 
preamble. Non-EGUs who wish to participate (e.g., RE sources) may 
submit registration criteria to participate in the ATCS. The ATCS will 
allow the trading and holding of ERCs that qualify for Clean Power Plan 
compliance in a system that also will be used to determine compliance. 
Quarterly, an affected EGU under the federal plan must submit 
information and data consistent with part 75.\87\ These quarterly 
submission dates are the 30th of April, July, October and January 
corresponding with the quarterly data ending the month previous the 
submission deadline (e.g., an April 30, 2024 submission would include 
data from January through March of 2024). The data that are posted 
online would be publicly available.
---------------------------------------------------------------------------

    \87\ See section IV.D.11 of this preamble for more information.
---------------------------------------------------------------------------

    Non-EGU ERC generating sources are required to submit generation 
data annually (see section IV.C.3 of this preamble for a comprehensive 
discussion of non-EGU ERC generating sources). The data must follow the 
EM&V procedures delineated in section IV.D.8 of this preamble. Because 
of the required rigor of the EM&V process, the EPA provides a time 
frame of January 1 to June 1 of the year that follows the data's 
inception to complete all EM&V processes (e.g, 2024 RE data must go 
through the EM&V process and be submitted to the EPA no later than June 
1, 2025). After receiving all emission and generation data from ERC 
generating sources and affected EGUs, the EPA will issue ERCs through a 
NODA as described in section IV.D.6 of this preamble. The EPA is 
proposing to issue ERCs annually. ERCs are acquired and traded 
throughout the compliance period. An affected EGU is responsible to 
hold sufficient ERCs that qualify for Clean Power Plan compliance in 
its ATCS compliance account by November 1 at midnight of the year 
following the conclusion of the compliance period.\88\
---------------------------------------------------------------------------

    \88\ This true-up process is further described in section 
IV.D.10 of this preamble.
---------------------------------------------------------------------------

    The process for transferring ERCs from one account to another is 
quite simple. A transfer would be submitted providing, in a format 
prescribed by the agency, the account numbers of the accounts involved, 
the serial numbers of the ERCs involved, and the name and signature of 
the transferring authorized account representative or alternate. If the 
transfer form containing all the required information were submitted to 
the EPA and, when the Administrator attempted to record the transfer, 
the transferor account included the ERCs identified in the form, the 
Administrator would record the transfer by moving the ERCs from the 
transferor account to the transferee account within 5 business days of 
the receipt of the transfer form.
10. Compliance With Emissions Standards
    Once the compliance period has ended, affected EGUs would have a 
window of opportunity to evaluate their reported emissions and obtain 
any ERCs that they might need to cover their emissions during the 
compliance period. The agency proposes to require sources to 
demonstrate compliance, i.e., ERC true-up, on November 1 of the year 
after the last year in the compliance period. For example, if the first 
compliance period comprises the three years 2022, 2023, and 2024, then 
the ERC transfer deadline \89\ for that first compliance period (after 
which point the EPA would evaluate compliance) would be on November 1, 
2025. The agency also requests comment on an earlier ERC transfer 
deadline, such as June 1 or March 1, of the year after the last year in 
the compliance period. Each ERC issued in the proposed rate-based 
trading program would, if applied, be averaged into the compliance rate 
as one MWh of energy with zero CO2 emissions deemed 
associated with it for the compliance period that includes the year for 
which the ERC was issued or be averaged into a later compliance period. 
Consequently, each affected EGU would need, as of the ERC transfer 
deadline, to have in its compliance account enough ERCs usable for its 
compliance obligations for the compliance period. The authorized 
account representative could identify specific ERCs to be applied, but, 
in the absence of such identification or in the case of a partial 
identification, the Administrator would deduct on a first-in, first-out 
basis. The ERCs that are used to meet compliance obligations are moved 
from the compliance account to the EPA's retirement account. ERCs that 
are deducted for compliance will remain in the system in an EPA 
account, which ensures they will not be used again.
---------------------------------------------------------------------------

    \89\ The ``ERC transfer deadline'' is the deadline for 
transferring allowances that can be used for compliance in the 
previous compliance period to a source's compliance account.
---------------------------------------------------------------------------

    The EPA will use the submitted generation, CO2 emissions 
and ERCs in the affected EGU's compliance account to calculate an 
average emission rate for the EGU. It is the responsibility of an 
affected EGU to calculate the number of ERCs that will need to be held 
in a compliance account to meet the EGU's compliance obligations. The 
method for determining the quantity of ERCs needed to meet compliance 
obligations has been discussed previously in an example. To reiterate 
the process, the affected EGU would need to solve for the number of 
zero-emitting MWh (i.e., ERCs) that would need to be added to the total 
MWh of the EGU to make the adjusted emission rate equal to the emission 
standard.
[GRAPHIC] [TIFF OMITTED] TP23OC15.013


[[Page 65010]]


    If an affected EGU fails to hold sufficient ERCs to comply with its 
emission standard then, upon notification of the deficiency, the owners 
and operators of the affected EGU must provide, for deduction by the 
Administrator, two ERCs as soon as available for every ERC that the 
owners and operators failed to hold as required to cover emissions, in 
addition to the ERCs owed for compliance in that next period. The owed 
ERCs will be deducted from the EGU's compliance account as soon as they 
are available in this account; the Administrator will not wait until 
the next true-up date to make this deduction. The two ERCs owed for 
each ERC needed for compliance but not supplied is in addition to any 
other recourse provided in sections 113(a)-(h) or section 304 of the 
CAA. This requirement to surrender two times the ERCs needed to make up 
the shortfall for the prior period is an ongoing obligation until 
compliance is achieved, and there is an ongoing obligation to comply in 
the current period. Failure to surrender these replacement ERCs is an 
additional violation that may be subject to federal enforcement. The 
EPA solicits comment on sources owing two ERCs to make up for each 
insufficient ERC in previous compliance periods and whether two for one 
is the proper make-up rate or whether there should be a stricter or a 
more lenient ratio.
    The EPA believes that it is important to include a requirement for 
an automatic deduction of ERCs. The deduction of one ERC per ERC that 
the owners and operators failed to hold would offset this failure. The 
deduction of another ERC per ERC that the owners and operators failed 
to hold provides a strong incentive for compliance with the ERC-holding 
requirement by ensuring that non-compliance would be a significantly 
more expensive option than compliance. This is consistent with other 
existing trading programs.
11. Other ERC Tracking and Compliance Operations Provisions
    These sections also would provide that the Administrator could, at 
his or her discretion and on his or her own motion and consistent with 
existing federal trading programs, correct any type of error that he or 
she finds in an account in the ATCS. In addition, the Administrator 
could review any submission under the rate-based trading program, make 
adjustments to the information in the submission, and deduct or 
transfer ERCs based on such adjusted information. These provisions are 
a standard part of other trading programs administered by the EPA 
including the ARP and the CSAPR (see, e.g., 40 CFR 72.96, 73.37, 
97.427, and 97.428). The EPA solicits comment on potential alternatives 
for error correction that may be simpler or more efficient.
12. Banking of ERCs
    The EPA is proposing to allow unlimited banking of ERCs within and 
between the interim and final compliance periods. This means that if an 
affected EGU has more ERCs than are necessary during true-up, it may 
save (i.e., bank) those ERCs for application during a future compliance 
period. The EPA requests comment on whether there should be a 
quantitative limit or cap on the number of ERCs that can be banked. The 
EPA also requests comment on whether an ERC should be eligible to be 
banked between the interim and final compliance periods. The EPA is 
also proposing that ERCs will not expire after any duration of time. 
Other trading rules that the EPA has instituted (e.g., CSAPR) do not 
have expiration on the tradable properties. The EPA requests comment on 
the shelf-life of an ERC.
    ERC ``borrowing'' is a flexibility that the EPA is not proposing, 
but is soliciting comment on. ERC borrowing is the concept that an 
affected EGU may use an ERC that the EGU will acquire in a future 
compliance period to meet its current compliance obligations. The EPA 
requests comment on a methodology that would allow ERC borrowing while 
maintaining the integrity of the compliance obligations. The EPA also 
has reservations concerning this concept due to the fact that future 
ERC generation is not guaranteed.
13. Emissions Monitoring and Reporting
    The EPA would require that emission and generation data be reported 
to the EPA quarterly starting on April 30, 2022, and continuing every 3 
months thereafter (i.e., the 30th of April, July, October, and 
January). The EPA proposes that affected EGUs subject to the rate-based 
federal plan trading program would monitor and report CO2 
emissions in accordance with 40 CFR part 75. The EPA is proposing to 
require affected EGUs in all states covered by the rate-based federal 
plan trading program to monitor and report CO2 emissions by 
and output data by January 1, 2022. Quarterly reporting would be 
required, with each quarterly report due to the Administrator 30 days 
after the last day in the quarter. The reporting would be in accordance 
with 40 CFR 75.60. The use of 40 CFR part 75 certified monitoring 
methodologies would be required. Many affected EGUs that might be 
covered by the proposed federal plans will generally have no changes to 
their monitoring and reporting requirements and will continue to 
monitor and submit reports under 40 CFR part 75 as they have under 
existing programs. The EPA anticipates fewer than 50 (approximately 10 
of these affected EGUs are coal fired with the remainder being gas and 
oil fired that will qualify for an excepted monitoring methodology) 
affected EGUs, that would not otherwise be subject to the ARP, will 
have to purchase and install additional continuous emissions monitoring 
system (CEMS) and data handling systems or upgrade existing equipment 
in order to meet the monitoring and reporting requirements of this 
program. Several of the affected EGUs not otherwise subject to the ARP 
are subject to the MATS program and therefore will have already 
installed stack flow rate and/or CO2 monitors in order to 
comply with the MATS rule which are also necessary to comply with this 
rule. The CEMS used to comply and report data for MATS will be used for 
this rule to generate and report CO2 emissions data without 
having to install duplicative monitors. The same CO2 and 
stack gas flow rate monitored data used in conjunction with mercury and 
other CEMS to calculate a toxic pollutant emission rate may be used to 
calculate a CO2 mass or CO2 emission rate for 
this program. The Regional Greenhouse Gas Initiative (RGGI), ARP, MATS 
and this rule all refer to CEMS installed and certified in accordance 
with 40 CFR part 75. RGGI and ARP currently require the reporting of 
CO2 mass emissions on an hourly basis and cumulative totals 
at the end of each calendar quarter. The same monitors and data 
collected may be used for multiple purposes for RGGI, ARP, MATS and 
this rule. Relying on the same monitors that are certified and quality 
assured in accordance with 40 CFR part 75 ensures cost efficient, 
consistent, and accurate data that may be used for different purposes 
for multiple regulatory programs. The majority of the affected EGUs 
covered by this rule are already affected by the Acid Rain and/or RGGI 
programs and will have minimal additional monitoring and reporting 
requirements.
    The EPA also requests comment on requiring monitoring and reporting 
of CO2 mass and net generation for the year before the 
initial compliance period begins, i.e., to commence January 1, 2021. 
Only monitoring and reporting would be required in 2021--compliance 
with an enforceable emission standard would commence on the compliance

period schedule that is detailed in section III.D of this preamble.

E. Federal Plan and State Plan Interactions

1. Interstate Trading
    The EPA proposes that all affected EGUs within states that are 
covered by the federal plan, if a rate-based federal plan is finalized 
for two or more states, would be allowed to trade with one another 
since there will be an assured commonality in the ERC currency and 
criteria surrounding the trading program. In addition, the EPA 
proposes, consistent with the provision for ``ready-for-interstate-
trading'' plans in the EGs, that affected EGUs located in states with 
approved ready-for-interstate-trading state plans using the 
subcategorized uniform rate standards, and a common credit currency 
(i.e., ERCs representing one zero-emitting MWh) may trade with affected 
EGUs operating under the federal trading program established in this 
federal plan.
    Rate-based EGUs subject to the federal plan and rate-based EGUs in 
ready-for-interstate-trading state plans will be able to trade ERCs 
seamlessly across jurisdictional borders because of the assurances of 
being presumptively approvable. Ready-for-interstate-trading states 
must submit information that lists all affected EGUs and the EGU type 
to the Administrator to be able to trade within the federal trading 
program. To be able to trade in the federal trading program an affected 
EGU that is subject to a ready-for-interstate-trading state plan must: 
(1) Certify and authorize a designated representative per section 
IV.D.1 of this preamble; and (2) register a general account in the 
federal trading program, ATCS, in order to have a means of transferring 
ERCs with entities operating in the federal trading program. An 
affected EGU under a state plan will not register a compliance account 
in the federal system because it will not be demonstrating compliance 
under the federal plan. Compliance will be achieved in the affected 
EGU's corresponding state plan. Affected EGUs under a state plan have 
the ability to acquire ERCs through the federal trading program. These 
ERCs will be stored in the EGU's general account in the federal trading 
program. To use these ERCs for compliance purposes, the ERCs must be 
transferred to the EGU's compliance account in the state's program. The 
EPA proposes to provide software to states to maintain a state's 
compliance and tracking program. A state's program will have the 
capability to interact with the federal trading program and software, 
ATCS, for transferring ERCs if the state is ready-for-interstate-
trading. A state's program can be tailored to meet its needs while 
still providing a platform for a state to be transferring ERCs between 
the state's system and the federal trading program. ERCs can flow 
between a state system and the federal trading program bilaterally. The 
EPA acknowledges that states may have additional criteria for 
generating ERCs that are not outlined as part of the federal plan, but 
because the EPA will have vetted these criteria through a state plan 
approval these ERCs will be able to be traded within the federal 
trading program.
2. Treatment of States Entering or Exiting the Trading Program
    The EPA proposes that a rate-based trading federal plan may be 
replaced by a state plan for a future compliance period. The EPA is 
proposing that a state must transition to a state plan at the 
conclusion of a federal plan compliance period. The EPA requests 
comment on whether there are reasons that a state should be allowed to 
transition from a federal plan to a state plan in the middle of a 
compliance period and if so what requirements should be put in place to 
do so while ensuring the integrity of both the federal plan and the 
state plan and while enabling the affected EGUs covered by the plans to 
understand and meet their compliance requirements. If a state subject 
to the federal plan transitions to a state plan, any affected EGU 
impacted by the change remains responsible for meeting any outstanding 
obligations under the federal plan. To make the transition to a state 
plan, a state must have an approved state plan as laid out in sections 
VIII.D and VIII.E of the final EGs.

V. Mass-Based Implementation Approach

A. Trading Program Overview

    In addition to the rate-based implementation approach discussed 
above, the EPA is proposing a mass-based implementation approach for 
the federal plan. As with the rate-based approach, this proposed 
federal plan is also a proposed model trading rule that states can 
adopt. The mass-based approach that the agency proposes to implement is 
a mass-based trading program (i.e., an emissions budget trading 
program, also referred to as an ``allowance system''). This section 
provides a brief overview of the proposed mass-based trading program. 
The next sections describe the various elements of the proposed trading 
program in further detail.
    A mass-based trading program establishes an ``aggregate emissions 
limit'' that specifies the maximum amount of emissions authorized from 
affected EGUs included in the program, and creates allowances that 
authorize a specific quantity of emissions. The total number of 
allowances created are equal to, and constitute, the emissions budget 
or the aggregated emissions limit expressed in terms of short tons of 
emissions. The EPA is proposing that allowances be issued in short tons 
for the federal plan.
    Each facility with affected EGUs in the program must surrender 
allowances equal in number to the quantity of the emissions of its 
affected EGUs during the compliance period. A facility with affected 
EGUs may buy allowances from, or transfer or sell allowances to, other 
affected EGUs or other entities that participate in the market. A mass-
based trading program provides sources with great flexibility in 
choosing compliance strategies.
    In the proposed mass-based trading program for the federal plan, 
the aggregate emissions limit for a state is its statewide mass-based 
emission goal (or ``mass goal'') as finalized in the Clean Power Plan 
EGs. The proposed approach to linking states for interstate allowance 
trading is detailed in section III.A.1 of this preamble; in an 
interstate trading program the aggregate emissions limit is the sum of 
the mass goals for the covered states.
    The EPA believes that a broad trading region provides greater 
opportunities for cost-effective implementation of controls compared to 
a smaller region. Therefore, the agency proposes that an affected EGU 
in any state covered by the proposed mass-based trading federal plan 
may use for compliance an allowance distributed in any other state 
covered by the mass-based trading federal plan. The EPA also proposes 
to provide for allowance trading between affected EGUs and other 
entities in states with approved mass-based-trading state plans that 
meet the conditions specified in section III.A.1 of this preamble, 
above, and affected EGUs and other entities in any state covered by the 
federal plan mass-based trading program.
    A mass-based trading program can provide environmental certainty at 
lower cost than other policy mechanisms, because it assures the 
specified emissions outcome while maximizing compliance flexibility 
available to individual affected EGUs. Further, allowance banking in 
such a program creates an incentive to make reductions earlier than 
required. Mass-based trading programs are relatively

[[Page 65012]]

simple to operate, which reduces administrative time and cost. 
Additionally, to inform the mass-based trading approach proposed here, 
the EPA draws upon more than two decades of experience implementing 
federally-administered mass-based emissions budget trading programs 
including the ARP SO2 trading program, the NOX 
Budget Trading Program, CAIR, and CSAPR.
    In the proposed mass-based trading program federal plans, the 
emissions limits in each state would be the mass goals that the EPA 
promulgated in the Clean Power Plan EGs (if there is interstate trading 
then the sum of the mass goals for the states in the trading program 
would constitute the aggregate emissions limit). The total amount of 
allowances distributed in each state for each year would sum to the 
state's mass goal for that year. As detailed in section V.E of this 
preamble, the EPA is proposing that a state covered by the federal plan 
can determine its own approach to distribute allowances, and believes 
that state allocation has important merits. The EPA would distribute 
allowances in a state if the state does not choose to do so, as 
detailed below.
    Each allowance would authorize the emission of one short ton of 
CO2 during the compliance period applicable to the 
allowance's vintage year or a later compliance period. The proposed 
approach to distribute allowances, including three types of allowance 
set-asides, is discussed in section V.D of this preamble, below.
    After each compliance period, an affected EGU would surrender for 
compliance an amount of allowances equal to its emissions during the 
course of the compliance period. See section V.C of this preamble for 
the proposed length of the multi-year compliance periods. Allowances 
could be transferred, bought, sold, or banked (carried over for future 
use) and any party could participate in the allowance market. The EPA 
is not proposing allowance ``borrowing'' (i.e., the bringing forward of 
future-period allowances for use in an earlier period); the multi-year 
compliance periods inherently provide the flexibility to schedule 
relatively greater emission reductions for later years within each 
period, as discussed further in section V.C of this preamble. In the 
proposed mass-based trading program, the emission standard applied to 
individual affected EGUs is the requirement to surrender emission 
allowances equal to reported emissions for each compliance period.
    The EPA also proposes that a state may choose to replace the 
federal plan allowance-distribution provisions with its own allowance-
distribution provisions (i.e., to determine the distribution of 
allowances for its EGUs or other entities) using a state allowance-
distribution methodology. State allowance distribution can have 
important advantages, because it allows a state to design and shape 
allowance allocation to its specific goals and characteristics, and 
because states may have additional flexibility on allocation 
approaches, including auctions. See section V.E of this preamble for 
further discussion of the proposed approach for state-determined 
allowance-distribution methodologies.
    This proposed requirement to hold and surrender allowances equal to 
emissions for each compliance period would apply to all reported 
emissions from a facility's affected EGUs including any emissions from 
co-fired biomass if biomass is included as an eligible measure. Section 
IV.C.3 of this preamble discusses an approach on which the EPA requests 
comment on the inclusion of biomass as an eligible measure and on a 
proposed option where the agency would identify qualified biomass 
feedstocks (i.e., biomass feedstocks that are demonstrated to be a 
method to control increases of CO2 levels in the atmosphere) 
and potential methods for demonstrating compliance, and thus reduce the 
mass emissions attributed to a biomass co-fired affected EGU. If the 
EPA took such an approach, then for purposes of compliance with the 
proposed mass-based federal plan trading program, the affected EGU 
would need to hold allowances equal to its emissions less the emissions 
attributed to the co-fired qualified biomass; such an approach would 
reduce the number of allowances the affected EGU would need to hold to 
demonstrate compliance. The EPA requests comment on this approach.

B. Statewide Mass-Based Emissions Goals

    In the Clean Power Plan EGs the EPA established statewide mass-
based emission goals (``mass goals'') for all states that are 
equivalent to the rate-based goals. As discussed in section V.C of this 
preamble, below, the EPA proposes to implement the mass-based trading 
program with multi-year compliance periods that are consistent with the 
compliance timing provisions in the Clean Power Plan EGs, i.e., two 3-
year compliance periods followed by a 2-year compliance period in the 
Interim Period, and successive 2-year periods in the Final Period. In 
the Clean Power Plan EGs, the EPA established mass goals for all states 
for this pattern of compliance periods. The EPA proposes to use those 
mass goals promulgated in the Clean Power Plan EGs as the mass limits 
(i.e., emissions budgets) for any state covered by the mass-based 
trading program (or, if implementing interstate trading, then the EPA 
would use the sum of a covered group of states' mass goals as the 
aggregate mass limit). The EPA is not opening for comment the 
determinations, made in the Clean Power Plan EGs, of each state's mass 
goals. The mass goals are provided for convenience in Table 8 of this 
preamble.

C. Compliance Timing and Allowance Banking

    The EPA proposes to evaluate compliance (i.e., compare emissions 
from affected EGUs to allowances held by facilities) in multi-year 
periods. A multi-year compliance period provides greater flexibility to 
affected EGUs and reduces administrative burden, compared to a single-
year compliance period. The EPA seeks to strike a reasonable balance 
between providing flexibility and reducing burden while assuring that 
any noncompliance can be addressed in a timely fashion.
    The compliance periods in the proposed mass-based trading program 
would be the same as promulgated in the Clean Power Plan EGs, i.e., the 
Interim Period would be divided into three compliance periods: A 3-year 
compliance period (2022 through 2024), a second 3-year compliance 
period (2025 through 2027), and then a 2-year compliance period (2028 
and 2029), for the Interim Period. As in the EGs, the Final Period 
would be divided into successive 2-year compliance periods commencing 
in 2030. The EPA would evaluate compliance only after the end of a 
compliance period in the mass-based trading federal plan, e.g., if a 
compliance period is 3 years long, the agency would evaluate compliance 
only after the end of the third year in the period. The EPA is not 
reopening for comment the compliance periods promulgated in the Clean 
Power Plan EGs.
    Some existing GHG mass-based trading programs (i.e., emissions 
budget trading programs) use multi-year compliance periods. The RGGI 
uses 3-year compliance periods, along with intervening compliance 
requirements. The RGGI intervening compliance requirement is that 
sources must hold allowances to cover 50 percent of emissions for the 
first two calendar years of each 3-year compliance period; at the end 
of each 3-year compliance period sources must hold allowances to cover 
100 percent of emissions for the period and allowances already deducted 
for the intervening requirement are

[[Page 65014]]

subtracted from the 3-year obligation.\90\ The California Air Resources 
Board (CARB) Cap-and-Trade Program also uses 3-year compliance periods, 
along with intervening compliance requirements. The CARB intervening 
requirement is to evaluate compliance on 30 percent of each source's 
previous year's emissions every year, and evaluate compliance for the 
remainder of emissions every 3 years.\91\ The EPA proposes to evaluate 
compliance after each multi-year compliance period and is not proposing 
to implement intervening compliance requirements such as those in the 
RGGI or CARB programs, however, the agency requests comment on the 
inclusion of such requirements.

---------------------------------------------------------------------------

    The EPA recognizes that the compliance periods provided for in this 
rulemaking are longer than those historically and typically specified 
in CAA rulemakings. As reflected in long-standing CAA precedent, 
``[t]he time over which [the compliance standards] extend should be as 
short term as possible and should generally not exceed one month.'' See 
e.g., June 13, 1989 Guidance on Limiting Potential to Emit in New 
Source Permitting and January 25, 1995 Guidance on Enforceability 
Requirements for Limiting Potential to Emit through SIP and Sec.  112 
Rules and General Permits. The EPA determined that the longer 
compliance periods provided for in this rulemaking are acceptable in 
the context of this specific rulemaking because of the unique 
characteristics of this rulemaking, including that CO2 is 
long-lived in the atmosphere, and this rulemaking is focused on 
performance standards related to those long-term impacts.
    The EPA proposes that allowances may be banked for use in any 
future compliance period, with no restriction on the use of banked 
allowances, including from the Interim Period (2022 through 2029) into 
the Final Period (2030 and thereafter). The agency requests comment on 
the proposal to provide for unlimited allowance banking including the 
banking of Interim-Period allowances for use during the Final Period.
    Allowance ``borrowing'' is a type of timing flexibility wherein 
allowances from a future compliance period may be ``brought forward'' 
and used for compliance in an earlier compliance period (thus reducing 
the amount of allowances available for the future period). The EPA 
notes that the proposed multi-year compliance periods inherently 
provide the flexibility to emit at relatively higher amounts in earlier 
years of a given compliance period by using allowances from future 
years within each compliance period (e.g., if the first compliance 
period covers years 2022 through 2024, a vintage 2024 allowance could 
be used to cover a ton emitted in 2022). The EPA is not proposing to 
allow allowance borrowing across compliance periods in the mass-based 
trading federal plans; however the agency requests comment on the use 
of borrowing across compliance periods.
    Allowance borrowing across compliance periods would increase the 
complexity of the proposed mass-based trading program and reduce the 
flexibility for states to replace the federal plan with an approved 
state plan. First, in order for borrowing to occur, the EPA would have 
to make allowances from future compliance periods available early so 
that sources could use these future allowances in earlier compliance 
periods. The EPA proposes to record allowances in source accounts for 
one compliance period at a time in order to maximize the opportunities 
for a state to replace the federal plan (or replace the allowance-
distribution provisions of the federal plan) with an approved state 
plan (or approved state allowance-distribution methodology). The EPA 
proposes to allow a state to replace the mass-based trading federal 
plan (or the federal plan allowance-distribution provisions) with a 
state plan (or state allowance-distribution methodology) for a 
compliance period for which the agency has not yet recorded allowances 
in source accounts. Recording allowances for multiple compliance 
periods at once--in order to make future-period allowances available 
for borrowing--would therefore limit these opportunities for states to 
take over implementation (or implementation of the allowance-
distribution).
    If allowance borrowing from a future compliance period were 
allowed, and the EPA provided the opportunity for a state to replace 
the federal plan for a year for which allowances had already been 
borrowed and retired for compliance in an earlier period, those 
borrowed allowances would constitute additional emissions beyond the 
levels specified in the Clean Power Plan EGs. In that event, the EPA 
would then need to address whether and how to remove allowances from 
circulation to prevent inflation of the allowable emissions at affected 
EGUs in the remaining states subject to the federal plans (to ``repay'' 
the borrowed allowances). To avoid disruption to sources already 
subject to the mass-based trading federal plan, the EPA is not 
proposing to allow allowance borrowing across compliance periods.
    Although not proposing to provide for allowance borrowing across 
compliance periods, the agency requests comment on the potential 
inclusion of allowance borrowing in the proposed mass-based trading 
federal plans, including from how far into the future to allow 
allowances to be borrowed, how inclusion of borrowing would affect 
opportunities for states to take over implementation of the EGs (or 
implementation of the allowance-distribution provisions in the mass-
based trading federal plan), how to address removing the extra 
allowances from circulation that would result if borrowed allowances 
originate in a state that subsequently withdraws from the mass-based 
trading program, and on other complexities that borrowing across 
compliance periods would introduce.
    The agency proposes to require sources to demonstrate compliance, 
i.e., allowance true-up, on May 1 of the year after the last year in 
the compliance period. For example, if the first compliance period 
comprises the three years 2022, 2023, and 2024, then the allowance 
transfer deadline \92\ for that first compliance period (after which 
point the EPA would evaluate compliance) would be on May 1, 2025. The 
agency also requests comment on an earlier or later allowance transfer 
deadline.
---------------------------------------------------------------------------

    \92\ The ``allowance transfer deadline'' is the deadline for 
transferring allowances that can be used for compliance in the 
previous compliance period to a source's compliance account. For 
further information see section V.G of this preamble.
---------------------------------------------------------------------------

    The EPA proposes to evaluate compliance (i.e., allowance true-up) 
at the facility level, not at the individual affected-EGU level, in the 
mass-based trading program. Facility-level compliance may ease 
implementation compared to unit-level compliance; each facility has a 
single compliance account in which to hold allowances to cover 
emissions from all its affected EGUs rather than having individual 
unit-level compliance accounts. Fewer accounts may make it easier for 
the designated representatives to manage their allowances. The EPA has 
adopted facility-level compliance in previous emissions budget-trading 
programs including the ARP, see 70 FR 25162, at 25296-98 (May 12, 
2005); the CAIR FIP, see 71 FR 25328, at 25365 (April 28, 2006); and 
the CSAPR, see 75 FR 45210, at 45323 (August 2, 2010). The EPA

[[Page 65015]]

would continue to track unit-level emissions--while evaluating 
compliance at the facility level--allowing us to track increases and 
decreases of pollutants at individual EGUs.

D. Initial Distribution of Allowances

    Establishing a mass-based trading program requires that 
policymakers establish an approach for the initial distribution of 
allowances, historically referred to as ``allowance allocation.'' The 
EPA believes that states may be well positioned to design their own 
allowance distribution approach because they can take into account a 
wide range of considerations and tailor decisions to the particular 
characteristics and preferences of their state. The EPA proposes that 
states have the flexibility to determine their own approach for 
distributing allowances in the federal plan, through a process that is 
detailed in section V.E of this preamble. The EPA believes that states 
should have the opportunity to make decisions about allowance 
distribution and that they may have additional flexibility on 
approaches, including allowance auctions. The EPA is also proposing an 
allocation approach that we intend to use in the event we implement the 
federal plan in a state that does not choose to determine its own 
allowance-distribution approach. The EPA requests comment on all of 
these, and any other, approaches to distribute allowances.
    The initial allowance allocation approach that is based on 
historical data does not affect the environmental results of the 
program or generation patterns; regardless of the manner in which 
allowances are initially distributed, the finite total number of 
allowances limits allowable emissions across all affected EGUs. 
Allowance allocations also are not intended to prescribe or suggest any 
unit-level compliance requirements nor do they limit unit-level 
operational flexibility, because a mass-based trading program provides 
operators of affected EGUs with the flexibility to buy, sell, or bank 
allowances. Allowance allocation is simply a procedure by which 
allowances are distributed into the marketplace so that they may be 
available for affected EGUs to acquire as desired to authorize 
emissions under the program. However, because these allowances are 
finite in number and thus a limited resource, they have value, and as a 
result, initial allowance allocations may raise issues of equity among 
recipients.
    Thus the agency recognizes that its choice of allocation 
methodology is important from the perspective of distributional 
effects, and the importance of selecting an approach that is fair and 
reasonable in light of this consideration and the overall purpose of 
CAA section 111 informs the agency's thinking in this proposal. We also 
invite comment on these considerations, and on any other factors or 
considerations which commenters believe should inform the allocation 
method.
    The EPA believes that the most reasonable basis for an initial 
allowance allocation procedure is an approach that uses historical data 
reported by the affected EGUs subject to the requirement to hold 
allowances under this program. This approach relies on known data 
rather than future projections. The EPA believes this approach is 
preferable because any approach tied to future indicators (e.g., the 
expected future EGU-level pattern of emissions or the ultimate use of 
allowances) would depend on future outcomes that the EPA cannot project 
with perfect certainty in advance. Basing allocation on historical data 
is also consistent with the EPA's approach to initial allowance 
allocation under previously established mass-based trading programs.
    The EPA proposes to allocate most CO2 emission 
allowances to existing affected EGUs in each state covered by a final 
mass-based trading federal plan, with set-asides for a portion of 
allowances (discussed in more detail below). For each compliance 
period, the agency would distribute CO2 allowances in each 
covered state in the amount of the state's CO2 ``mass goal'' 
(i.e., the state's CO2 statewide mass-based emission goal as 
promulgated in the Clean Power Plan EGs) for that compliance period. 
For example, if a compliance period is 3 years long, the EPA would 
aggregate and distribute allowances for all 3 years at the same time. 
The agency is not proposing to allocate allowances to new EGUs, which 
do not have a compliance obligation under this proposed federal plan. 
For each year of the program, the agency proposes to allocate most of 
the allowances directly to affected EGUs using a historical-generation-
based approach. The EPA is also proposing three set-asides of 
allowances, which are detailed below.
    Although the EPA cannot anticipate the future EGU-level pattern of 
emissions, it is possible to consider potential future emission 
patterns at the source subcategory level. In developing the Clean Power 
Plan EGs, the agency conducted analysis of emission reduction potential 
in the two affected EGU source subcategories, i.e., electric utility 
steam generating units (steam generating units) and NGCC units. With 
that analysis as a basis, the EPA requests comment on an alternative 
allocation approach that would first divide the total number of 
allowances from each state's mass goal into source subcategories based 
on analysis done in developing the source category-specific 
CO2 emissions performance rates promulgated in the EGs and 
then allocate to affected EGUs within each category based on shares of 
historical generation. This alternative is described later in this 
section.
    The EPA recognizes that states may prefer different approaches to 
distribute CO2 allowances from the EPA's approach and that 
there may be advantages in having states tailor and apply their own 
allocation approach. Therefore, the agency is proposing that a state 
may choose to replace the federal plan allowance-distribution 
provisions with its own allowance-distribution provisions, using any 
approach to distribute allowances that the state chooses, including 
methods that the EPA is not proposing here, provided that the state's 
approach addresses emissions leakage and includes a Clean Energy 
Incentive Program. The proposed requirements for addressing leakage, as 
well as how the EPA proposes to implement the Clean Energy Incentive 
Program for the mass-based federal plan, are detailed in sections V.E 
and V.D.4 of this preamble, respectively.\93\ The EPA proposes that a 
state could choose its own method for distributing allowances for any 
compliance period including the first period that would commence in 
2022. The proposed process for a state to replace federal plan 
allowance-distribution provisions with its own allowance-distribution 
provisions is detailed in section V.E of this preamble.
---------------------------------------------------------------------------

    \93\ As detailed in section V.E in this preamble, we propose 
that a state that chooses to determine its own allowance-
distribution approach under the proposed federal plan must address 
leakage through its allocation strategy (such as the set-aside 
approaches in section V.D.3 of this preamble). We request comment on 
whether a state may make a justification regarding leakage as 
detailed in section V.E of this preamble.
---------------------------------------------------------------------------

    The following sections discuss and request comment on the EPA's 
proposed approach to allocate CO2 allowances to affected 
EGUs based on shares of historical generation, the proposed timing of 
allowance recordation, three proposed allowance set-asides, allocations 
to units that change status, and the proposed approach for states to 
replace federal plan allocation provisions with their own allowance-
distribution approaches. In addition, we

[[Page 65016]]

request comment on alternative allowance distribution approaches--such 
as auctioning or allocations to load-serving entities--that the EPA or 
states might adopt. The EPA requests comment on all of these aspects of 
allowance distribution.
1. Proposed Allocation Approach and Alternatives
    The EPA proposes to allocate most of the CO2 allowances 
in the mass-based trading program to affected EGUs based on historical 
generation (output) data. The EPA also proposes three allowance set-
asides. The first would set aside a portion of allowances in each state 
from the first compliance period only; this set-aside is for a proposed 
Clean Energy Incentive Program that is detailed in section V.D.4 of 
this preamble. The second would set aside a portion of allowances in 
each compliance period except for the first period; the EPA proposes to 
distribute allowances from this set-aside to affected EGUs via an 
updating output-based approach as detailed in section V.D.3 of this 
preamble). The third would set aside 5 percent of allowances in each 
state, in all compliance periods, to be distributed to RE projects as 
detailed in section V.D.3 of this preamble. In summary, the proposed 
set-asides include:

    (1) Clean Energy Incentive Program. This set-aside would be of 
first compliance period allowances only.
    (2) Output-based allocation set-aside. This set-aside would 
start in the second compliance period and continue for each 
compliance period.
    (3) Renewable energy set-aside. This set-aside would be 
implemented in all compliance periods.

    This section describes the proposed historical-generation-based 
approach that the agency would use to allocate all allowances except 
for the set-aside allowances. The EPA is proposing affected-EGU-level 
allocations (based on available data) in every state. Further detail on 
this proposed allocation approach is provided in the Allowance 
Allocation Proposed Rule TSD in the docket. The affected-EGU-level 
allocations resulting from this proposed historical-generation-based 
approach are provided in the docket in an appendix to the TSD. The 
agency requests comment on the proposed historical-generation-based 
allocation approach and on other allocation approaches.
    The EPA proposes to allocate the historical-generation-based 
portion of the allowances (i.e., the mass goal minus the set-asides) 
\94\ to individual affected EGUs based on each affected EGU's share of 
the state's historical generation, using 2010 through 2012 data. The 
calculation steps for this proposed historical-generation-based 
allocation approach are as follows:
---------------------------------------------------------------------------

    \94\ In the first compliance period this would be the mass goal 
minus the Clean Energy Incentive Program set-aside and the RE set-
aside. In all other compliance periods this would be the mass goal 
minus the output-based allocation set-aside and the RE set-aside.
---------------------------------------------------------------------------

    (1) For each unit in the list of likely affected EGUs in each 
state, identify annual net generation values for the historical period 
of 2010 through 2012 (reflecting affected-EGU-specific generation 
assumptions incorporated in the data adjustments, e.g., assumed 
capacity factor for ``under construction'' units). For a year for which 
an affected EGU has no generation data (e.g., a year before the year 
when a unit started operating), assign the affected EGU a value of 
zero.\95\ (See step 2, below, for how zero values would be treated in 
the calculations.)
---------------------------------------------------------------------------

    \95\ The EPA proposes that for affected EGUs that were under 
construction and began operation during 2012 or after 2012 (and thus 
don't have a full year of generation data from the 2010 through 2012 
period), the allocation calculations be based on the same 2012 
generation estimate as the agency used in the Clean Power Plan EGs 
for the goal-setting calculations. That is, the EPA proposes to 
estimate 2012 generation for such units based on a unit's net summer 
capacity and assuming a 55 percent capacity factor for gas units and 
a 60 percent capacity factor for steam units.
---------------------------------------------------------------------------

    The EPA proposes to use a 3-year historical period (i.e., 2010 
through 2012) to reflect unit-level operations over time. In the Clean 
Power Plan EGs, the EPA identified a reasonable basis for using 
aggregate data at the regional level largely based on the most recent 
data year (in that case, 2012) to inform the establishment of category-
wide EGs (as opposed to individual, unit-specific parameters). As a 
distinct matter, in this context the EPA is considering data at the 
unit level to inform unit-specific initial allowance allocations; 
notwithstanding that these allowance allocations do not impose any 
unit-level compliance requirements in and of themselves, the EPA finds 
it reasonable to consider a multi-year data period to inform unit-level 
initial allocations in order to consider a broader range of unit-
specific operations over time.
    (2) Determine each affected EGU's average generation value by 
averaging all (non-zero) 2010 through 2012 annual generation values for 
the unit. The proposed approach would use only non-zero values in 
calculating a unit's average generation. For example, if generation 
data for a unit were available for only 2011 and 2012 then the EPA 
would only use the 2011 and 2012 values to determine the unit's 
unadjusted average generation value. The EPA included generation from 
all units in the historical data set in the proposed allowance 
calculations and calculated allowances for all such units; the agency 
requests comment on the treatment of generation from and allocations to 
units that operated in the historical data set but retire before the 
start of the program.
    (3) In each state, sum the average generation values from all 
affected EGUs to obtain that state's ``total average historical 
generation.''
    (4) Divide each affected EGU's average generation value by the 
state's total average historical generation to determine that affected 
EGU's share of the state's total average historical generation.
    (5) Multiply each affected EGU's share of the state's total average 
historical generation by the historical-generation-allocation portion 
of the state's mass goal (i.e., the state's mass goal minus the set-
asides) to determine that affected EGU's allocation.
    The agency believes that this proposed historical-generation-based 
allocation approach is a reasonable approach for several reasons:
     The agency believes that the proposed historical-
generation-based approach maximizes transparency and clarity of 
allowance allocations. The EPA has placed in the docket the historical 
generation data and the calculations used to determine the proposed 
affected-EGU-level allocations. The agency also placed the proposed 
affected-EGU-level allocations, resulting from these calculations, into 
the docket. These calculations can be relatively easily replicated.
     To calculate allocations, the EPA proposes to use 
historical affected-EGU-level net generation data compiled using a 
methodology similar to the Emissions & Generation Resource Integrated 
Database methodology. The proposed calculation approach is described 
further below and in the Allowance Allocation Proposed Rule TSD in the 
docket. The historical-data methodology is described in the 
CO2 Emission Performance Rate and Goal Computation TSD for 
Clean Power Plan Final Rule. The majority of the generation-unit-level 
data in this approach are from reports that emissions sources submit to 
the EPA under 40 CFR part 75 and to the EIA on forms EIA-860 and EIA-
923. The EPA believes these are the best data available to the agency 
at the time of this proposed rule for calculating affected-EGU-level 
allocations.
     Allocating based on historical data (as opposed to data 
not yet reported)

[[Page 65017]]

allows for the distribution of allowances prior to the start of the 
program, which can facilitate compliance planning.
    The proposed approach is transparent, based on reliable data, and, 
like the approaches used in the NOX SIP Call, the ARP, and 
CSAPR, based on historical data. For all these reasons, the agency 
believes that it is appropriate to use a historical-generation-based 
allocation methodology in this proposed rule. The EPA also requests 
comment on a historical-data approach based on historical emissions.
    The proposed historical-data-based allocations approach would not 
generally affect the ultimate pattern of generation across individual 
power plants, as compared to other methods of allocation. The 
combination of plants, and their contributing generation, that will be 
used to meet a particular demand for electric power will be based on 
the relative efficiency (cost of production) of available plants. The 
relevant measure of this efficiency is the marginal cost of generation, 
which for a particular power plant would be the sum of the cost of 
additional fuel to generate an additional MWh, additional maintenance 
costs to increase output by an additional MWh, and costs associated 
with the additional emissions that result from generating an additional 
MWh. In a mass-based trading program, additional emissions must be 
covered by additional allowances, so the cost of emitting is the price 
of the allowances that must be consumed to authorize those emissions. 
These emissions-related costs of electricity production are the same 
regardless of whether the allowances used to cover those emissions were 
initially allocated to the user or whether they were acquired 
subsequently in the marketplace.
    The same concept applies to any other cost of electricity 
production. For example, a coal-fired EGUs operator would account for 
the cost of consuming coal to produce generation whether or not the 
coal was discovered already on-site, given to the unit at ``no 
charge'', or purchased from the marketplace; in all cases, the 
combustion of that coal consumes its value (i.e., it can no longer be 
sold). Similarly, the approach taken to distribute allowances does not 
affect the cost accounting for emissions at units because the use of 
any tradable allowance has an opportunity cost--a firm loses the 
opportunity of selling an unneeded allowance when it emits an 
additional ton. Because a firm loses the opportunity of selling an 
unneeded allowance when it emits an additional ton, even the emission 
of a ton covered by a ``free'' allowance causes the generator to incur 
the cost of emissions based on the market price of allowances the owner 
must forgo by emitting that ton and using that allowance.
    The proposed historical-data-based allocation approach would not be 
expected to have any effect on freely competitive electricity markets, 
because the marginal cost of emitting under the mass-based trading 
program is determined by the level of the overarching mass goals and is 
not affected by the distribution of the underlying allowances. This 
marginal cost of emitting is what will inform prices, outputs, and 
competition among power plants. While cost-of-service markets are 
structured differently from competitive markets, the regulated utility 
still makes the dispatch decision on the basis of marginal costs among 
the units in its fleet, which is not affected by the amount of 
allowances that any particular unit in that fleet was initially 
allocated (assuming a competitive allowance market).
    The EPA recognizes that some stakeholders are concerned about the 
potential future distribution of emissions at the facility level, and 
possible effects on communities. However, for the reasons discussed in 
the above paragraphs, allowance allocations that do not change based on 
future activity (such as allocations under the proposed historical-
generation-based approach) do not affect the distribution of emissions 
under the program. This proposed rule is expected to achieve 
significant emission reductions across the electric power sector; see 
section IX of this preamble for discussion of anticipated broad 
benefits to communities.
    In addition to the proposed historical-data-based allocations 
approach, the EPA also requests comment on other allocation approaches. 
One alternative approach on which the agency requests comment is 
similar to the proposed approach in that it allocates allowances based 
on historical generation. However, this alternative approach would 
divide the total number of allowances from a state's mass goal (minus 
the set-asides) into affected EGU source categories--based on analysis 
done in developing the source category-specific CO2 
emissions performance rates promulgated in the Clean Power Plan EGs--
before determining unit-level allocations. The EPA requests comment on 
this alternative approach because dividing the allowances in a state by 
source category in this manner may result in an initial distribution of 
allowances that would be closer at the source-category level to the 
future category-level pattern of emissions, and thus to allowances 
ultimately used, than the proposed approach. To the extent that this 
category-level division of allowances is a reasonable proxy for the 
future category-level emissions pattern under the program, this 
approach may reduce wealth transfer between parties that occurs as a 
consequence of a less-anticipatory initial allocation procedure. The 
EPA cannot observe in advance the future affected-EGU-level pattern of 
emissions.
    In this alternative approach, for each state the EPA would multiply 
historical steam-generating-unit generation by the steam-generating-
unit source category-specific CO2 emissions performance 
rate, and multiply historical NGCC-unit generation by the NGCC-unit 
source category-specific CO2 emissions performance rate. The 
EPA would do these calculations for each of the compliance periods in 
the Interim Period using the glide path interim performance rates, and 
for the Final Period using the final performance rates. These 
performance rates are shown in Table 6 in section IV.B of this 
preamble, above. The EPA established the source category-specific 
emissions performance rates in the Clean Power Plan EGs (see section VI 
of the final EGs); these rates are not within the scope of this 
proposed federal plan rulemaking. Next, for each compliance period the 
EPA would split the total number of allowances from the state's mass 
goal (minus the set-asides) into affected-EGU source categories in 
proportion to the values resulting from the above calculation. The EPA 
would then allocate the steam-generating-unit portion of the allowances 
to individual SGUs using the same historical-generation-based approach 
described above, and would also allocate the NGCC-unit portion of the 
allowances to individual NGCC units using the historical-generation-
based approach.
    The EPA notes that there are multiple approaches that policymakers 
may use to distribute allowances, beyond the proposed or alternative 
allocation approaches we included in this proposed rule. Examples of 
other allocation approaches include allocating based on historical heat 
input (fuel) or historical emissions data, rather than historical 
generation data. The choice to use historical data for allocation 
(e.g., generation, heat input, or emissions) means that the 
distribution of allowance value will be based on past behavior. For 
example, allocations based on historical emissions would benefit those 
that have historically been the largest emitters, whereas allocations 
based on historical heat input or generation (output) would benefit 
those that have

[[Page 65018]]

historically used the most fuel or generated the most electricity.\96\ 
Alternatively, allocations could be distributed based on projected or 
observed future activity (e.g., generation, heat input, or emissions).
---------------------------------------------------------------------------

Cap and Trade Program for Pollution Control, EPA, 2003.
---------------------------------------------------------------------------

    The proposed and alternative allocation approaches would determine 
most of the allocations before the start of the program. Other 
potential allocation approaches would change allocations for future 
compliance periods based on future activity--referred to as 
``updating'' allocations. This proposed rule includes an updating-
allocation component, as we are proposing to set aside a portion of the 
allowances in each state for distribution using an updating output-
based approach as detailed in section V.D.3 of this preamble. The EPA 
requests comment on the use of other updating allocation approaches.
    Another allowance allocation approach that could minimize the 
difference between the initial allowance allocation and the ultimate 
distributional pattern of allowance use for compliance is to conduct an 
auction, a process whose express intent is to align the allocation of a 
scarce good (in this case, the limited authorization to emit 
CO2) with the parties most willing to pay for its use. Many 
ascribe benefits, in terms of economic efficiency, to the use of 
auctioning as a means of allocating allowances. The EPA notes that some 
states (e.g., RGGI participating states) have used auctions to 
distribute allowances and have used auction revenues for a variety of 
purposes, including the implementation of demand-side EE measures 
intended to help reduce electricity rate impacts and overall program 
costs, as well as targeted investments in low-income communities. The 
EPA believes that if it conducted allowance auctions, any revenue from 
such auctions received by the agency must be deposited in the U.S. 
Treasury under federal law.\97\ As a result, the EPA notes that states 
implementing state plans may have greater flexibility than the federal 
government would to direct auction funds for particular activities. The 
agency requests comment on the idea of auctioning all, or a portion of, 
each state's allowances in the proposed federal plan, on how much of 
each state's allowances to auction if not the entire amount, on the 
frequency (e.g., yearly or every few years), design of auctions (e.g., 
spot or advance; first, second-price or other) and who may participate 
in the auction.
---------------------------------------------------------------------------

    \97\ The EPA believes authority to conduct auctions is located 
in CAA section 111 alone, as well as by its reference to CAA section 
110(c) FIPs. The statutory definition of a FIP authorizes 
``techniques (including economic incentives, such as marketable 
permits or auctions of emissions allowances).'' 42 U.S.C. 7602(y).
---------------------------------------------------------------------------

    The EPA requests comment on an alternative approach, which is 
allocating a portion of the allowances to load-serving entities (LSEs) 
rather than to affected EGUs. LSEs are the entities responsible for 
delivering power to retail consumers.
    Allocation to LSEs can help mitigate bill impacts on electricity 
consumers when applied in concert with certain additional design 
features. In particular, if LSEs commit and/or are required to pass 
through to ratepayers the value from their selling of the allocated 
allowances, this approach can mitigate the impact of electricity bill 
increases on consumers that might otherwise result from application of 
the federal plan. As described in the Allowance Allocation TSD, this 
type of approach can also help to avoid or mitigate the potential for 
windfall profits for affected EGUs. The EPA could apply this approach 
by conditioning the receipt of allowances by LSEs on the pass through 
to consumers of any allowance value if necessary.
    The EPA requests comment on the design and utility of allocating 
allowances to LSEs to help mitigate electricity price impacts. In 
particular, the EPA requests comment on options to establish conditions 
requiring pass through of allowance value and verification of such 
pass-through, whether it would be appropriate to identify any 
conditions related to equitable distribution of allowance value among 
ratepayer categories, as well as the EPA's legal authority to apply any 
such conditions.
    The EPA requests comment on the additional design aspects of any 
potential allocation to LSEs, including but not limited to the 
following questions: In particular, what metric should provide the 
basis for LSE allocation, e.g., electricity demand served by the LSE, 
population served by the LSE, emissions associated with generation 
serving the LSE, or some other metric. If emissions are used as the 
basis for such allocation, what approach should be taken: On a 
historical basis or a continually updated basis, on the basis of 
estimated emissions for the relevant region or some other basis, and 
using what data to calculate such emissions. Also, the EPA requests 
comment on the form by which LSEs may distribute the allowance value to 
rate-payers, e.g. as a fixed amount, through reduced rates, etc. 
Finally, the EPA requests comment on what share of the total number of 
allowances should be distributed to LSEs and what monitoring and 
reporting requirements may be necessary to support an effective 
program.
    The EPA also requests comment on the proposed historical-
generation-based allocation approach, the alternative approach that 
divides total allowances from a mass goal into source subcategories 
before allocating to individual affected EGUs within each source 
category based on historical generation, and on the other alternative 
approaches described in this section. The EPA also requests comment on 
allocating allowances to all generation in a state (including non-
emitting generation) using a historical-generation-based approach. The 
agency also requests comment on the proposed allowance set-asides, 
which are detailed below. The agency requests comment on allocation 
approaches that may minimize the impact of this proposed rule on small 
entities. The EPA also requests comment on any other approaches to 
distribute allowances. The agency notes that we propose to provide that 
any state may choose to replace the federal plan allocation provisions 
with an allocation approach of its choosing as discussed below. 
Finally, with regard to alternative allocation methodologies (either 
those specifically mentioned in this proposal or other allocation 
methodologies), the EPA requests comment on how those alternatives 
would satisfy the requirement that in a mass-based program where new 
sources are not included as part of the program, the allocation 
methodology must address leakage to new fossil fuel-fired sources.
2. Timing of Allowance Recordation
    The proposed historical-data-based allocation approach--which the 
EPA proposes to use to allocate all of the allowances in each state 
except for the set-aside allowances--is a one-time determination that 
is not updated. The allocations resulting from this approach would be 
determined prior to the start of the program. The EPA proposes to 
record the historical-data-based allowances for each compliance period 
in source accounts prior to the start of each compliance period, and to 
record allowances for one compliance period at a time. Recording 
allowances prior to the start of a compliance period provides certainty 
to affected EGUs of their allocations in advance of when the allowances 
are needed for compliance and can facilitate long-term planning.

[[Page 65019]]

Recording allowances for one compliance period at a time provides 
flexibility for a state to replace the federal plan with its own plan 
in a timely way. As discussed in section V.F of this preamble, the EPA 
proposes to allow a state to replace the federal plan with its own 
approved state plan, for a compliance period for which allowances have 
not yet been recorded (the proposed schedule for allowance recordation 
is detailed below). The EPA also proposes that a state could choose to 
replace the federal plan allocations to its affected EGUs (and other 
entities) with its own allocations approach, for a compliance period 
for which allowances have not yet been recorded as detailed in section 
V.E of this preamble.
    The agency proposes to record allowances for the mass-based trading 
program in accounts of affected EGUs 7 months prior to the start of 
each compliance period. For example, if compliance periods are 3 years 
long and the first compliance period comprises the years 2022, 2023, 
and 2024, the EPA would record allowances for 2022, 2023, and 2024 by 
June 1, 2021. The EPA requests comment on the proposed approach of 
recording allowances 7 months prior to the start of each compliance 
period, and on an alternative of recording allowances 13 months prior 
to the start of each compliance period. See section V.D.3 of this 
preamble for timing of recordation of allowances from the proposed set-
asides.
3. Allowance Set-Asides To Address Leakage to New Sources
    In addition to the general allocation method proposed above, the 
EPA is proposing two additional components of allowance allocation 
under a mass-based federal plan. These two set-asides are being 
proposed to satisfy the requirement in the final guidelines that mass-
based plans demonstrate that they have addressed the risk of leakage to 
new unaffected units, as specified below.\98\
---------------------------------------------------------------------------

    \98\ The EPA is also proposing a third set-aside, for a Clean 
Energy Incentive Program, which is detailed in section V.D.4 of this 
preamble, below.
---------------------------------------------------------------------------

    The final EGs specify the concern of leakage, which is defined in 
section VII.D of the final EGs preamble as the potential of an 
alternative form of implementation of the BSER (e.g., the rate-based 
and mass-based state goals) to create a larger incentive for affected 
EGUs to shift generation to new fossil fuel-fired EGUs relative to what 
would occur when the implementation of the BSER took the form of 
standards of performance incorporating the subcategory-specific 
emission performance rates representing the BSER. The final EGs 
specified that mass-based plan approaches must address leakage, because 
the form of the mass goals may ultimately impact the relative 
incentives to generate and emit at affected EGUs as opposed to shifting 
generation to new sources, with potential implications for whether the 
mass goal implements or is consistent with the BSER and overall 
emissions from the sector. These circumstances are much less likely to 
be present under a rate-based plan approach, where the form of the goal 
ensures sufficient incentive to affected existing EGUs to generate and 
thus avoid leakage, similar to the CO2 emission performance 
rates. By requiring mass-based plan components that address leakage, 
the final EGs ensure that mass goals are equivalent to the 
CO2 emission performance rates and are thus an equivalent 
expression of the BSER. Section VII.D of the final EGs details the 
requirement for addressing leakage and why it is needed, and section 
VIII.J of the final EGs specifies options for mass-based state plan 
components that address leakage. We are proposing, as part of the mass-
based approach under the federal plan and model rule, to implement 
allowance allocation approaches to address leakage, specifically 
through establishing an output-based allocation set-aside and a set-
aside that encourages the installation of RE.
    As noted in the EGs, if a state were to adopt allowance set-aside 
provisions exactly as they are outlined in this model rule once it is 
finalized, the requirement for that state plan to address leakage would 
be considered presumptively approvable.
    Section VIII.J of the final EGs provides a discussion of how set-
asides can effectively address leakage in a mass-based plan approach. 
That section of the final EGs also describes why the allowance 
allocation alternative for addressing leakage must be chosen for the 
federal plan instead of the option to regulate new non-affected fossil 
fuel-fired EGUs. This is because the EPA does not have authority to 
extend regulation of and federal enforceability to new fossil fuel-
fired sources under CAA section 111(d), and therefore we cannot include 
new sources under a federal mass-based plan approach.
    The set-asides we are proposing--described in detail below--would 
establish a pool of allowances that would be allocated to affected EGUS 
or other entities based upon criteria designed to address leakage.
    These set-asides are essentially a type of ``economic incentive'' 
authorized by the CAA as a means of pollution prevention and control, 
and the expected benefits of this particular type of economic incentive 
to address leakage make it appropriate here.\99\ The EPA believes these 
set-aside programs are both authorized and consistent with the purpose 
of the Clean Power Plan under CAA section 111(d) and the specific 
requirements specified in the final guidelines. They do not have the 
effect of increasing the stringency of the federal plan because the 
overall budget of allowances (representing allowable emissions) remains 
the same.
---------------------------------------------------------------------------

    \99\ In designing a federal plan under CAA section 111(d), the 
EPA recognizes its authority as being, in some sense, the same as 
that available under CAA section 110(c), where the use of economic 
incentives is authorized. See CAA section 302(y), 42 U.S.C. 7602(y) 
(authorizing use of ``economic incentives'' in FIPs).
---------------------------------------------------------------------------

    The EPA is aware of the successful use of set-asides and similar 
programs in other emissions trading programs. The following are 
examples of set-asides and similar programs used in other federal air 
quality rules.
    The EPA has previously established set-asides of emissions 
allowances in FIPs under CAA section 110. For example, in the CSAPR, 
the EPA used a 5 percent set-aside for new units, because we believed 
it was ``important to have a small new unit set-aside in each state to 
cover new units within the budget that was set aside in order to 
address the state's significant contribution and interference with 
maintenance.'' (75 FR 45310; August 2, 2010). This was important, in 
the EPA's view, because it allowed for growth in the electric utility 
sector consistent with the EPA's modeling, where new units showed up in 
the modeling output as surrogate facilities representing potential new 
EGUs that come online in future years in response to demand increases 
or other market drivers.\100\ As between a choice of requiring these 
new units to purchase their allowance on the open market, versus being 
treated in the same manner as existing--and generally understood to be 
less efficient and more polluting--units, i.e., by being eligible to 
receive an initial allowance allocation out of the new unit set-aside, 
the EPA chose the latter.

OAR-2009-0491, at 3-4 (June 2011).
---------------------------------------------------------------------------

    As part of the ARP under Title IV of the 1990 CAA Amendments, 
Congress established a ``conservation and renewable energy reserve'' 
account. See CAA section 404(f), 42 U.S.C. 7651c(f). This is in essence 
a set-aside account of

[[Page 65020]]

SO2 allowances which the regulated utilities could earn by 
undertaking ``qualified energy conservation measures'' and ``qualified 
renewable energy'' projects. The size of the reserve was set at 300,000 
allowances, and utilities could earn one SO2 allowance for 
every 500 MWh of energy saved through demand-side EE savings or RE 
generation. In the first years of the program, utilities received bonus 
allowances equivalent to close to 3,000 tons of avoided SO2 
emissions, while achieving co-benefits from reductions in other 
pollutants, and, in the words of one industry representative, 
``creating a culture change where utilities are looking for 
opportunities everywhere.'' \101\ The reserve program was nonetheless 
undersubscribed, and the EPA and other parties have learned from this 
case and made adjustments to similar programs to promote participation. 
This proposal seeks to minimize the administrative burden associated 
with participation in this rule's proposed set-asides.

    In the NOX SIP Call, the EPA encouraged states to 
consider including energy efficiency and renewables as a strategy in 
meeting their emission budgets through the use of set-asides. See 63 FR 
57356, 57438 (October 27, 1998). A number of states created RE and 
demand-side EE set-asides in their SIPs in response, and later, for the 
implementation of CAIR. A ``roundtable'' meeting with 25 states in 2006 
indicated that states that had established these programs were 
generally having success with them, and provided a forum for exchanges 
of ideas on how to handle a variety of implementation issues, such as 
over- and under-subscription, application issues, compliance and 
verification, the appropriate size of a set-aside account, how to 
garner public input on which projects are selected, and other 
issues.\102\ In general, the EPA believes its experience and those of 
the states with these set-aside programs support the view that they are 
an effective means to spur clean energy projects, which in turn we 
believe can help to reduce the risk of leakage in this instance.\103\

---------------------------------------------------------------------------

    Below, the EPA describes two potential allowance set-asides. First, 
the EPA proposes a set-aside for allowances distributed to existing 
NGCC units based on output (i.e., output-based allocation) to mitigate 
emission leakage to new sources. Second, the EPA proposes a set-aside 
for electricity generation from qualifying renewables. This set-aside 
also addresses the potential for leakage to new sources, as increased 
RE capacity can serve electricity demand in place of new sources. The 
EPA also solicits comment on other set-aside options that could address 
leakage, including a set-aside that provides an incentive for demand-
side EE. The EPA seeks comment on all aspects of the set-aside options 
specified in this section. This includes the inclusion of a set-aside, 
the method for allocation of allowances to set-asides, the size of the 
set-asides, the requirements for the process of distribution, 
eligibility requirements for receiving set-aside allowances, the 
proposed process for redistribution of undistributed allowances from 
each set-aside, and any other appropriate set-asides.
a. Set-Asides for Output-Based Allocation
    The EPA is proposing a set-aside approach referred to as output-
based allocation, which provides targeted allocations of a limited 
portion of allowances to existing NGCC units as a means of mitigating 
leakage. The EPA believes that this proposed set-aside would reduce 
incentives for generation to shift away from EGUs covered under mass-
based plans to new unaffected EGUs. We seek comment on all aspects of 
this proposal and its underlying rationale.
    Under the output-based allocation approach we are proposing, 
beginning with the second compliance period, a portion of the total 
allowances within each mass-based federal plan state would be allocated 
to existing NGCC units based, in part, on their level of electricity 
generation in the previous compliance period. Each eligible EGU would 
get a larger allowance allocation from this set-aside if it generates 
more, such that owner/operators of eligible EGUs will have an incentive 
to generate more in order to receive more allowances. Because the total 
number of allowances is limited, this allocation approach will not 
exceed the overall emission goal. Instead, it merely modifies the 
distribution of allowances in a manner designed to align the generation 
incentives for eligible EGUs in mass-based states with new emitting 
EGUs that are not subject to a mass-based limit, mitigating emissions 
leakage.
    The EPA is inviting comment on key parameters for the appropriate 
design of the output-based allocation approach used for this proposed 
set-aside. Key parameters to be identified under the output-based 
allocation approach include which affected EGUs receive the allocation, 
the timing of the set-aside's allocation procedure, the allocation 
rate(s), and the size of the set-aside. The EPA also invites comment on 
what other parameters may be relevant for design of an appropriate 
output-based set-aside.
    The EPA first solicits comment on which EGUs should be eligible to 
receive output-based allocation from the set-aside. The EPA proposes 
that only NGCC units subject to the final EGs receive output-based 
allocation from the set-aside. The EPA recognizes that performance of 
output-based allocation may be improved by targeting which units 
receive this additional incentive. In particular, this approach can 
most effectively address emission leakage if targeted to those affected 
EGUs subject to a mass goal that face the greatest difference in their 
incentive to generate relative to otherwise similar EGUs that are not 
subject to a mass goal. As noted in the discussion of the allocation 
rate below, new combustion turbines (i.e., NGCC units and simple cycle 
combustion turbines) would be expected to generate more absent this 
set-aside. Therefore, the difference in generation incentives between 
affected stationary combustion turbines subject to a mass goal and 
otherwise similar new stationary combustion turbines that are not 
subject to a mass goal is likely one of the most salient deviations in 
production incentives to address.
    The EPA also requests comment on extending output-based allocation 
from this set-aside to affected SGUs. Output-based allocation for SGUs 
may increase generation subject to the mass limit, leading to reduced 
generation and emissions from new emitting sources. However, the EPA 
does not propose this approach because it is not as effective as 
output-based allocation to NGCC units.

[[Page 65021]]

This is because output-based allocation to SGUs would incentivize 
generation from relatively high-emitting EGUs, which would likely 
increase allowance prices as other emission reductions are made to 
respect the overarching mass limit. This approach would thus strongly 
counteract the intended effect of lowering the production cost from 
sources subject to the proposed mass-based federal plan (compared to 
emitting sources not subject to the plan). The EPA also requests 
comment on extending output-based allocation from this set-aside to 
zero-emitting generators (including both renewable and nuclear 
generation), and how the design of the OBA set-aside for such 
generators would differ relative to the NGCC approach (e.g., the amount 
of allowances earned per MWh, the capacity-factor threshold, the size 
of the total set-aside).
    The EPA also proposes that this approach be targeted towards 
marginal generation that may not have otherwise occurred absent this 
set-aside, by providing allocations under this set-aside only to 
eligible EGUs that exceed a 50 percent capacity factor on a net basis 
over the compliance period, and only for the portion of their 
generation that exceeds that capacity factor.\104\
---------------------------------------------------------------------------

    \104\ Effectively, the allocation rate (defined below) of 
output-based allocation is zero up until this average capacity 
factor.
---------------------------------------------------------------------------

    The EPA also solicits comment on the timing of the output-based 
allocation set-aside's allocation procedure, which involves the 
relationship between the time at which eligible generation occurs and 
the vintage year(s) of the allowances allocated from this set-aside to 
recognize that generation. The EPA is proposing a lagged accounting 
procedure for this set-aside, where eligible generation that occurs 
during a given compliance period would receive allowances through this 
set-aside taken from vintage years in the subsequent compliance period. 
In keeping with this lagged accounting procedure, the EPA is proposing 
not to reserve any allowances of vintage years during the first 
compliance period (2022-2024) for allocation through this set-aside; 
eligible generation that occurs during the first compliance period 
would be recognized through this set-aside with allowances of vintage 
years from the second compliance period (2025-2027).
    The EPA is proposing this lagged accounting procedure because the 
amount and location of eligible generation in any given compliance 
period remains uncertain until the compliance period has ended and the 
relevant data has been reported and verified. Without this lagged 
accounting procedure, the EPA would have to withhold an amount of 
allowances for this set-aside from certain vintage years even as the 
corresponding compliance period was already underway. Given the size of 
this proposed output-based allocation set-aside in certain states, the 
EPA believes it would be more advantageous for affected EGUs to know in 
advance how many allowances they will be allocated in a given period, 
inclusive of allowances allocated through this output-based allocation 
set-aside.\105\
---------------------------------------------------------------------------

    \105\ The EPA recognizes that under this lagged accounting 
procedure, if the federal plan is replaced by a state plan in a 
future compliance period, the incentive to create eligible 
generation in the last compliance period subject to the federal plan 
is potentially diminished.
---------------------------------------------------------------------------

    The EPA requests comment on options for the allocation rate under 
this approach. The allocation rate is the number of allowances, in an 
amount equal to a specific amount of emissions, that the affected EGU 
receives per one net MWh of generation eligible for the set-aside. The 
EPA proposes to set the allocation rate equal to the rate-based 
emission standard (on a net basis) for new NGCC units under 111(b), in 
order to align the generation incentives across EGUs eligible for the 
set-aside and the type of new emitting source that would generate more 
absent this set-aside. Specifically, an additional MWh of eligible 
generation would earn the affected EGU allowances equal to the level of 
emissions permitted per MWh of net generation under the 111(b) new 
source standard, which is 1,030 lbs/MWh-net (Carbon Pollution Standards 
for new, modified, and reconstructed EGUs). The EPA requests comments 
on other values for the allocation rate. For example the allocation 
rate may be the expected net emissions rate of newly constructed NGCC 
units, the historical average emissions rate from NGCC units, or the 
NGCC or fossil steam source category-specific emissions performance 
rates promulgated in the Clean Power Plan EGs (see section VI of the 
final EGs).
    The EPA proposes to calculate an NGCC unit's capacity factor based 
on the previous compliance period's net generation and the net summer 
capacity of the unit. The EPA is proposing to require affected EGUs to 
report net generation to the agency.\106\ The EPA proposes to use net 
summer capacity as reported to EIA. In the alternative, the EPA 
proposes to require that NGCC units report net summer capacity directly 
to the EPA by adding it as a required data field in the certificate of 
representation that a unit's owner or operator would submit to the 
agency (see section V.G of this preamble). The EPA notes that the EIA 
net summer capacity data is reported at the generator level; if we add 
this data point to the certificate of representation it would be 
reported at the affected-EGU level, which would facilitate calculation 
of capacity factors. The EPA also requests comment on whether the 
``maximum load value,'' which is a parameter that EGUs report to the 
EPA in their monitoring plans, is a reasonable proxy for EGU-level net 
summer capacity for these calculations. The EPA also requests comment 
on an alternative approach of basing the capacity-factor calculation on 
nameplate capacity instead of net summer capacity, or other approaches 
to the calculation.
---------------------------------------------------------------------------

    \106\ See section V.H of this preamble for proposed monitoring 
and reporting requirements. The EPA proposes to make the reported 
generation data available to the public on the agency's Web site.
---------------------------------------------------------------------------

    The EPA proposes to determine the size of the output-based set-
aside once, before the start of the program, and not to change the size 
thereafter. The EPA proposes to determine the size of the set-aside 
assuming that it would incentivize existing NGCC to increase 
utilization to a 60 percent capacity factor. The assumed 60 percent 
capacity factor offers a way to limit the size of this set-aside, which 
allows the remainder of the allowances in a given compliance period to 
be allocated through the historical-generation approach (as detailed 
above) and the other proposed set-asides (as detailed below). 
Furthermore, limiting the size of the set-aside avoids the risk of 
incentivizing too much generation from eligible sources, as discussed 
further in the Allowance Allocation Proposed Rule TSD.
    The EPA proposes to determine the size of the output-based set-
aside using 2012 baseline data from the Clean Power Plan EGs.\107\ The 
EPA would calculate the size of the set-aside as 10 percent of the NGCC 
capacity in the state \108\ multiplied by the hours in a year 
multiplied by the allocation rate for the set-aside. The EPA requests 
comment on the proposed capacity data used as the basis for determining 
the size of the output-based set-aside, and alternative sources of 
capacity data that may be used for determining its size.

    The set-asides resulting from this proposed approach are shown in 
Table 9 of this preamble. The set-asides in the table would apply to 
every compliance period except for the first compliance period for 
which there would be no output-based set-aside. Although the size of 
the set-aside would remain the same for each compliance period, as the 
mass goals decrease with each step in the Interim Period and to the 
Final Period, the set-asides would constitute an increasing share of a 
state's mass goal. The Allowance Allocation Proposed Rule TSD further 
details the proposed approach to determine the size of the set-aside. 
The EPA requests comment on a potential limit for the size of the set-
aside in a compliance period based on a percentage of the state's total 
allowances for the compliance period.

    Given the proposed limit on the total size of the set-aside, and 
the amount of potential generation eligible for the set-aside, there 
may be fewer allowances available in the set-aside than can be earned 
at the allocation rate. The EPA proposes that, if the amount of total 
generation eligible for the set-aside multiplied by the allocation rate 
exceeds the size of this set-aside, then the allowances in this set-
aside would be allocated to eligible generation on a pro-rata basis.
    The EPA proposes that if the number of allowances allocated from 
the set-aside is less than the size of this set-aside, then the 
remaining allowances would be distributed to all affected EGUs using 
the historical-generation-based approach described above.
    The EPA proposes to provide notice of the capacity and generation 
data used to calculate allocations from the set-aside, and the 
resulting allocations, by August 1 of the first year in each compliance 
period, e.g., by August 1, 2025 for the compliance period that 
commences in 2025 (and based on the data from the prior compliance 
period). The agency proposes to provide 30 days for comment on the data 
and allocations, until August 31, and to provide notice of the final 
set-aside allocations by November 1 of the same year and record the 
allocations in the source accounts at that time. The EPA requests 
comment on other approaches to providing notice of the data and 
allocations.
    The EPA requests comment on all aspects of the proposed approach to 
calculate output-based set-aside allocations. Further details are in 
the Allowance Allocation Proposed Rule TSD in the docket.
b. Set-Asides for Renewable Energy Projects
    The EPA proposes to provide a set-aside of allowances for 
distribution to RE projects in each state covered by the proposed mass-
based federal plan, and is also proposing this for the mass-based model 
rule. The agency also requests comment on whether distribution should 
extend to DS-EE, CHP, and other types of projects. Under this program, 
the EPA would reserve a percentage of each state's allowances in a set-
aside account for each state. Developers of RE projects could apply to 
receive set-aside allowances based on the projected generation from 
eligible RE capacity.
    This set-aside is expected to address concerns regarding leakage by 
lowering the marginal cost of production of the incented clean energy 
technologies within the state. This will make RE more competitive 
against new sources, reducing the potential for leakage to new sources. 
While the proposed set-asides would provide additional incentive for 
the creation of additional RE capacity, it should also be noted that 
the proposed mass-based trading program itself would provide incentive 
for new and existing low and zero-emitting generation.
    In the context of the proposed federal plan, the EPA is proposing 
that it would create a unique set-aside for each state covered by a 
mass-based federal plan. Under a model rule, the state would create 
this set-aside. The allowances in each set-aside would be reserved from 
each vintage of the assigned mass goal to that state prior to 
allocation of allowances to sources. The EPA is proposing that 5 
percent of allowances will be reserved from the allocation for each 
state for the purpose of the set-aside. We are also requesting comment 
on options for a percentage of allowances to be reserved ranging from 1 
to 10 percent of total allowances in each state. The proposed 
percentage has been determined to provide a meaningful additional 
incentive for RE activities in each state, while ensuring that the vast 
majority of allowances are freely allocated to affected EGUs. The EPA 
made this conclusion based upon determining an appropriate volume of 
set-aside resources that, at a range of possible allowance prices, are 
projected to incent the development of additional RE projects. The 
analysis is provided in the docket as part of the Renewable Energy Set-
aside TSD. We note that, under the proposed framework, these allowances 
would be available to affected EGUs either in the marketplace or 
through subsequent distribution of unclaimed set-aside allowances, and

[[Page 65023]]

thus the provision of these set-asides does not affect the overall 
stringency of the program.
    In section V.D.5 of this preamble, below, the EPA is proposing that 
the size of the RE set-asides may grow over time as certain units shift 
out of the program.
    We are proposing, as part of the mass-based federal plan and model 
rule, that a project is eligible to receive set-aside allowances if it 
is RE that meets the eligibility requirements for rate-based ERC 
issuance as specified in section IV.C of this preamble and section 
VIII.K of the final EGs. This includes, for example, the requirement 
that only capacity incremental to 2012 is eligible for the set-aside. 
The agency requests comment on an additional potential condition that 
would limit eligibility to project providers that are also the owners 
or operators of affected EGUs. This approach has precedent in the 
eligibility requirements for the ARP set-aside, and would limit the 
entities eligible to receive set-aside allowances to those that are 
subject to the federal plan.
    The EPA is proposing that eligible RE capacity must meet the 
following conditions regarding geographic eligibility for both the 
federal plan and model rule. Eligible RE projects must be located in 
the mass-based state for which the set-aside has been designated. The 
agency invites comment on whether capacity outside the state should be 
recognized, and how that could be implemented. The EPA also proposes 
that the generation for which an entity receives allowances from the 
set-aside would not be eligible for ERC issuance in rate-based states.
    As specified in section IV.C of this preamble, the EPA is proposing 
that the same RE measures are eligible to receive set-aside allowances 
under a mass-based federal plan as would be eligible for ERC issuance 
under a rate-based federal plan and the model rule. Specifically, the 
following RE measures are eligible: On-shore wind, solar, geothermal 
power, and hydropower. The RE measure must also have the capacity to 
provide data quantified by a revenue-quality meter, a requirement that 
is further discussed in section IV.D.8 of this preamble. New nuclear 
units and capacity uprates at existing nuclear units are not proposed 
to be eligible to receive set-aside allowances. We do not think a set-
aside used as an incentive for incremental nuclear capacity is a useful 
way to address leakage to new sources during the performance period, 
due to unique costs and development timelines for incremental nuclear 
power. All other proposed aspects of the RE eligible measure types 
described in section IV.C of this preamble and the requests for comment 
included within that section also apply in the mass-based set-aside 
context for both the proposed mass-based federal plan and the proposed 
mass-based model rule. For example, we are requesting comment on the 
inclusion of other RE measures, incremental nuclear, demand-side EE 
measures, CHP and any other emission reduction measures beyond those 
mentioned here, as long as they meet the eligibility requirements 
outlined in the final EGs for rate-based crediting, as eligible 
measures to receive set-aside allowances. We particularly request 
comment on how a set-aside to provide an incentive from these 
particular measures will serve to address leakage to new sources. We 
also request comment on the implications of the inclusion of such 
technologies for the streamlined implementation of projection-based 
EM&V requirements of the set-aside specified below in a federal plan 
context across the applicable jurisdictions, while still maintaining 
necessary rigor. We request comment on the appropriateness of the 
biomass treatment requirements offered for comment in section IV.C.3 of 
this preamble in the context of a mass-based set-aside. We request 
comment on requirements for the treatment of CHP and WHP, in the 
context of the mass-based set-aside. We also request comment on 
appropriate processes through which, after the federal plan is 
finalized, the EPA and/or stakeholders could make a demonstration of 
the appropriateness of new measure types and the EPA could evaluate and 
approve the demonstration so that a new measure type can be considered 
eligible for the set-aside.
    To demonstrate that an RE project meets the requirements proposed 
above, in the context of a mass-based federal plan, it is proposed that 
the project proponent must provide the following: Documentation of the 
nature of the project and that it meets eligibility requirements, 
documentation that it will be located within the state in question, and 
a projection of expected annual MWh generation for an RE project. The 
EPA must approve the documentation of eligibility and the projection of 
MWh before the project becomes eligible for a distribution of the set-
aside allowances. In addition, the proponent must register for a 
general account in the EPA tracking system where the allowances would 
be recorded. See 40 CFR 62.16320 for the requirements to establish a 
general account. While the EPA is proposing to allow eligible resources 
to use a general account to receive any allowances allocated under this 
section, the EPA requests comment on extending the designated 
representative provisions in 40 CFR 62.16290 to eligible resources 
instead of the general account provisions. Requiring eligible resources 
to submit information similar to that collected in the certificate of 
representation in 40 CFR 62.16305 and to appoint a designated 
representative to act on behalf of all owners/operators for all 
projects requesting allowances may improve the EM&V process by making 
the eligible resources more accountable. The EPA requests comment on 
what documentation would be required if other measure types were 
considered eligible to receive set-aside allowances. We propose that 
the same process for approval of projects be applied in a model rule, 
with the state taking the approving role instead of EPA.
    The EM&V requirements for the mass-based set-aside differ from 
those for rate-based ERC issuance, particularly because it is based 
upon projections provided prior to generation rather than metered data 
provided after the generation occurs (though we are proposing that the 
projections will be checked against ex-post metered data). The 
projection method enables the distribution of set-aside allowances 
prior to the year during which the generation occurs. The EPA feels 
this still provides sufficient rigor because the set-aside does not 
directly affect program stringency. The reason that stringency is not 
affected is because of key differences between issuance of credits and 
distribution of set-aside allowances. Under rate-based implementation, 
each decision to issue an ERC based on a quantification of RE 
generation affects the ultimate amount of allowable CO2 
emissions, because the number of ERCs is determined by the amount of 
MWhs approved as eligible for ERC issuance and the ERC does not exist 
until the issuance decision is made. Thus the amount of ERCs that are 
issued can affect the stringency of the rule. As a result, the EPA has 
laid out specific requirements (including EM&V procedures) in the final 
Clean Power Plan, and in this proposed federal plan and model rule, to 
assure the environmental reliability of measures qualifying for ERC 
recognition under rate-based implementation. In contrast, any decision 
to recognize RE with set-aside allowance allocations under a mass-based 
approach does not affect the validity of the allowance itself and does 
not affect the CO2 emissions outcome because the ultimate 
amount of

[[Page 65024]]

allowable CO2 emissions is determined by the total number of 
allowances initially created (regardless of how they are distributed). 
As a result, while the EPA believes it is reasonable to consider a 
minimum set of qualifications for recognizing RE through these 
allowance set-asides to assure that the RE generation that is incented 
is actually produced, the EPA does not believe the overall integrity of 
mass-based implementation is significantly affected by the robustness 
of whatever eligibility requirements the EPA ultimately sets for RE 
recognition through allocation from these set-asides. This being said, 
the agency is proposing to require robust demonstrations of the 
eligibility and EM&V projections for RE generation submitted for the 
set-aside, demonstrations that are based on the best practices of 
existing programs. This is necessary to assure the delivery of RE as a 
result of the set-aside.
    The EPA proposes that the projections of MWh provided will be the 
basis of the distribution of set-aside allowances. A satisfactory 
demonstration of the future RE generation from an eligible project must 
use technically sound quantification methods that are reliable, 
replicable, and accompanied by underlying analytical assumptions and 
verifiable data sources used to demonstrate future performance. These 
methods, assumptions and data sources must be specified in 
documentation accompanying the projections. These projections and 
supporting documentation should all be provided in the set-aside 
project application, and that application must be approved by a third-
party verifier. The EPA invites comment on these proposed requirements 
for projections. We also request comment on whether set-asides should 
be distributed proportional to actual MWh provided by the installation 
in a prior year or compliance period, or another form of historical 
generation data. This type of allocation method could also be similar 
to the structure proposed for the output-based allocation set-aside. We 
propose that the same projection-based distribution basis be applied in 
a model rule, with the state taking the approving role instead of EPA.
    The EPA is proposing the following process for distribution of RE 
set-aside allowances. Starting prior to the compliance period, and 
going forward through the compliance period, RE providers in each state 
will have an opportunity to apply to the EPA or a designated agent to 
be approved as eligible to receive set-aside allowances in their state. 
This application must include all the requirements outlined above, 
including projections of expected MWh of generation. The EPA is 
proposing to accept RE set-aside project applications up to a deadline 
of June 1 in the year prior to the year during which the RE generation 
occurs (the ``generation year''). The EPA or its agent will review and 
approve the project as eligible and it will be entered into the pool of 
projects that will receive set-asides in any compliance period. If 
approved, the number of projected MWh in each generation year will be 
the basis of the number of allowances the provider will receive, as an 
input to the methodology specified below. The providers will have an 
opportunity to update projections for future generation years, these 
projections must be received by June 1 of the year prior to the 
generation year in question.
    On December 1 of the year prior to each year of the compliance 
period in question, the EPA is proposing to distribute allowances from 
the set-aside to approved providers. The agency is proposing to 
distribute set-aside allowances to approved RE providers pro-rata, with 
the number of allowances distributed to each provider according to the 
percentage of total approved RE MWh for that state that the approved 
MWhs from their project represent. This method is proposed because it 
treats all eligible RE projects equally in the distribution of set-
aside allowance. It also inherently provides a more significant 
incentive in states with less eligible RE generation, but will become 
less significant as RE generation increases. We also request comment on 
whether to restrict projects to a maximum number of allowances they can 
receive per MWh of generation, such as 1 allowance per MWh.
    After each generation year, RE providers receiving allowances will 
have to provide an M&V report with the MWhs of RE generation actually 
produced, to assure that they have met the projected level of 
generation. These M&V reports need to document that the generation was 
by an approved project, and the report should be approved by a third 
party verifier. As discussed in section IV.D.8 of this preamble (EM&V 
section for the rate-based approach), these data should be readily 
available from existing metering. The EPA requests comment on the 
process for submitting M&V reports with actual generation.
    If the project or program does not reach the MWhs projected in a 
particular generation year, the unfulfilled MWhs will be subtracted 
from that RE provider's MWhs eligible for the set-aside in the next 
generation year, or multiple years if the deficit exceeds the MWhs 
projected for the upcoming year. If this deficit is greater than 10 
percent in a particular year, the provider will need to provide an 
explanation of the deficit and will be required to reevaluate their 
projections for future years. If such deficits continue through all 
years of the relevant compliance period, the provider will be 
disqualified from receiving future set-asides for the following 
compliance period. We also request comment on whether a provider with 
continuing deficits should also be disqualified from receiving ERCs for 
the generation in question from states with rate-based plans. The 
agency requests comment on all of the specified aspects of this 
distribution process.
    The EPA is proposing that once allowances have been distributed to 
all approved providers, any remaining allowances in the set-aside, such 
as set-aside allowances designated for projects that no longer exist, 
will be redistributed to affected EGUs in the state in a pro rata 
fashion on the same distribution basis as their initial allocations 
were made. It is proposed that this will occur immediately after the 
distribution of set-aside allowances to eligible RE providers on 
December 1 of the year prior to the generation year in question. The 
EPA requests comment on this approach.
    We propose that the same distribution process as outlined above be 
applied in a model rule, with the state taking the approving role 
instead of the EPA.
    The EPA is also seeking comment, in the context of the proposed 
rate-based federal plan and model rule, on whether a portion of this 
set-aside should be targeted to RE projects that benefit low-income 
communities. This benefit could be in the form of MWh provided to the 
low-income community, financial proceeds from the project primarily 
benefiting the low-income community, or the project lowering utility 
costs of low-income rate-payers. The EPA seeks comment on how a low-
income community should be defined as eligible under this set-aside. We 
seek comment on how much of the set-aside should be designated as 
targeted at low-income communities. We also request comment on whether 
the methods of approval and distribution of allowances to projects that 
benefit low-income communities should differ from the methods that are 
proposed to apply to other RE projects.
    The EPA seeks comment, in the context of the proposed rate-based 
federal plan and model rule, on all aspects of this proposed RE 
allowance set-aside program, including whether it should be included as 
part of a mass-

[[Page 65025]]

based federal plan, the structure of the set-aside reserve, eligibility 
requirements for receiving set-aside allowances, demonstration of 
eligibility, and the process for distribution of allowances.
4. Provisions To Encourage Early Action
    For purposes of the proposed mass-based federal plan, the EPA 
proposes to implement the Clean Energy Incentive Program (CEIP) on 
behalf of a state by issuing early action allowances for eligible 
actions located in or benefitting the state. Eligible projects must 
commence construction in the case of RE or commence operations in the 
case of low-income EE after September 6, 2018, and will receive 
incentives based on the zero-emitting MWh they generate, or the energy 
savings they achieve, during 2020 and/or 2021.\109\ These early action 
allowances would be drawn from a third set-aside of allowances from the 
general distribution methodology. The EPA believes it is reasonable to 
establish the total amount of the early action set-aside in an amount 
equal to the pool of matching allowances. Thus, the EPA proposes that 
the total early action set-aside would be of an amount equal to the 
pool of matching allowances: No more than 300 million CO2 
allowances, depending on how many states are subject to a federal plan.
---------------------------------------------------------------------------

    \109\ As discussed in section VIII.B.2 of the final emission 
guidelines, in the case of a state that submits a final state plan 
including requirements for the state's participation in the CEIP, 
eligible RE projects may commence construction, and eligible EE 
projects may commence implementation, following the date of 
submission of a final state plan to the EPA. These projects must be 
implemented in or benefit the state that submitted the final state 
plan to the EPA, and may receive awards for the zero-emitting MWh 
they generate or the end-use energy savings they achieve during 2020 
and/or 2021.
---------------------------------------------------------------------------

    The EPA proposes to distribute the 300 million early action set-
aside allowances among the states based upon the amount of the 
reductions from 2012 levels each state must achieve relative to that of 
the other participating states. The EPA proposes to calculate these 
values as each state's proportional share of the total difference 
between the 2012 baseline and the 2030 mass goals.\110\ See Table 10 of 
this preamble for the proposed set-asides for each state under the 
mass-based federal plan. The agency proposes to set aside 100 million 
early action allowances from each of the 3 years in the first 
compliance period (2022, 2023, and 2024) for a total of 300 million 
allowances to be set aside. While the table shows set-asides for every 
state, the EPA proposes to implement this set-aside, according to the 
amounts listed in Table 10, only for those states for whom the EPA is 
implementing the mass-based federal plan. The EPA also requests comment 
on other approaches for determining the size of this set-aside in the 
mass-based federal plan.
---------------------------------------------------------------------------

    \110\ The 2012 baseline is from the CO2 Emission 
Performance Rate and Goal Computation TSD for the Clean Power Plan 
Final Rule. Where a state's relative share of the reductions from 
2012 levels would yield a set-aside of less than zero, the EPA 
proposes to assign such a state a set-aside equal to one percent of 
the state's 2030 mass goal and adjust the remaining state set-asides 
accordingly.
---------------------------------------------------------------------------

    For the purposes of the mass-based federal plan, the EPA is 
proposing to award early action allowances to two types of eligible 
projects that are located in or benefit the state for which the EPA is 
implementing a federal plan:
     RE investments that generate metered MWh from any type of 
wind or solar resources; and
     Demand-side EE programs and measures implemented in low-
income communities that result in quantified and verified electricity 
savings (MWh).
    Eligible RE projects must commence construction, and eligible EE 
projects must commence implementation, after September 6, 2018 for 
those states on whose behalf the EPA is implementing the federal plan. 
These projects will receive incentives for the MWh they generate or the 
end-use energy demand reductions they achieve during 2020 and/or 2021.
    The EPA proposes the following framework to implement the CEIP in 
the mass-based federal plan. First, the EPA proposes to create a set-
aside of early action allowances for all federal plan states, as 
described above. Second, the agency proposes to create an account of 
``matching'' allowances for each state participating in the CEIP--
regardless of whether a state is implementing a state plan or the 
agency is implementing a federal plan on its behalf. This distribution 
would reflect each state's pro rata share of a federal pool of 
additional allowances--based on the amount of the reductions from 2012 
levels the affected EGUs in the state are required to achieve relative 
to those in the other participating states \111\--which would be 
limited to the equivalent of 300 million short tons of CO2 
emissions. Thus, states whose EGUs have greater reduction obligations 
will be eligible to secure a larger proportion of the federal 
allocation upon demonstration of quantified and verified MWh of RE 
generation or demand side-EE savings from eligible projects realized in 
2020 and/or 2021. The EPA intends that a portion of these matching 
allowances would be reserved for eligible wind and solar projects, and 
a portion would be reserved for eligible EE projects implemented in 
low-income communities. The agency recognizes that there have been 
historical economic, logistical and information barriers to 
implementing EE programs in these communities, and therefore believes 
it is appropriate to reserve a portion of the federal pool to 
incentivize investment in these programs. The EPA requests comment on 
the size of reserve of matching allowances for eligible low-income EE 
programs as well as for eligible wind and solar projects. The EPA is 
proposing that unused allowances in either reserve would be 
redistributed among participating states. This redistribution could be 
executed according to the pro-rata method discussed above. 
Alternatively, unused matching EE or RE allowances could be swept back 
into a federal pool and distributed to project providers on a first-
come, first served basis. The EPA requests comment on these ideas as 
well as alternative proposals regarding the method for redistributing 
matching allowances, as well as the appropriate timing for such a 
redistribution.
---------------------------------------------------------------------------

    \111\ This is the same distribution method proposed above for 
the allocation of early action set-aside allowances to mass-based 
federal plan states.
---------------------------------------------------------------------------

    Following the effective date of a federal plan for a state, the 
agency will create an account of matching allowances for the state that 
reflects the pro rata share of the 300 million short ton CO2 
emissions-equivalent matching pool that the state is eligible to 
receive. Any matching allowances that remain undistributed after 
September 6, 2018 \112\ will be distributed to those states with 
approved state plans that include requirements for CEIP participation, 
as well as to those states on whose behalf the EPA is implementing a 
federal plan. These allowances will be distributed according to the pro 
rata method outlined above. Unused matching allowances that remain in 
the accounts of states participating in the CEIP on January 1, 2023, 
will be retired by the EPA. The EPA seeks comment on whether the number 
of matching allowances available to a state under the mass-based 
federal plan should be limited to a number equal to the number of early 
action allowances included in each federal plan state's early action 
set-aside.
---------------------------------------------------------------------------

    \112\ This may occur because not all states may elect to include 
requirements for CEIP participation in their state plans.
---------------------------------------------------------------------------

    Third, for any state subject to a federal plan, the EPA proposes to 
award early action allowances and matching allowances to eligible 
projects as

[[Page 65026]]

follows, based upon the quantified and verified MWh of generation or 
savings achieved by the projects in 2020 and/or 2021:
     For RE projects that generate metered MWh from any type of 
wind or solar resources: For every two MWh generated, the project will 
receive a number of allowances equivalent to one MWh from the state 
early action allowance set-aside, and a number of matching allowances 
equivalent to one MWh from the EPA.
     For EE projects implemented in low-income communities: For 
every two MWh in end-use demand savings achieved, the project will 
receive a number of allowances equivalent to two MWh from the state 
early action allowance set-aside, and a number of matching allowances 
equivalent to two MWh from the EPA.
    The EPA will address implementation details of the CEIP in a 
subsequent action. Allowances awarded by the EPA pursuant to the CEIP 
may be used for compliance by an affected EGU with its emission 
standards in any compliance period and are fully transferrable prior to 
such use. The EPA proposes to distribute any remaining early action 
set-aside allowances in a state--after distribution to all eligible 
projects in the state--to the affected EGUs in the state on a pro-rata 
basis in proportion to the initial allocations made to those EGUs under 
the mass-based federal plan.
    As discussed in section V.E of this preamble, the EPA proposes to 
allow any state where a federal plan is being implemented to take 
responsibility for distributing allowances. This will allow a state to 
tailor its allowance-distribution approach to the characteristics and 
preferences of the state. The EPA proposes that a state that chooses to 
replace the federal plan allocations with a state-determined approach 
must include a CEIP set-aside, as authorized in section VIII.B.2 of the 
final EGs. The EPA intends that such a state would have the same 
flexibilities as a state implementing a full state plan with respect to 
implementation of the CEIP. That is, the state would not be required to 
implement a set-aside of the same size as proposed in Table 10 of this 
preamble, but rather could choose how many of its allowances to set-
aside for the CEIP.
    The EPA requests comment on all aspects of implementing the CEIP 
under a mass-based federal plan approach, including (1) The size of the 
early action allowance set-aside; (2) the approach for distributing the 
early action allowance set-aside among states; (3) the timing of 
distribution of set-aside and matching allowances; (4) the amount of 
allowances awarded per eligible MWh generated or avoided; (5) the 
criteria for eligible projects, including criteria for awards to EE 
projects implemented in low-income communities; (6) the mechanism for 
reviewing project submittals and issuing early action allowances; (7) 
EM&V requirements for eligible projects; and, (8) the number of early 
action and matching allowances that should be awarded for each ton of 
emissions reduced from eligible generation or low-income efficiency 
projects to ensure a robust response to the program. The EPA also seeks 
comment on how states, tribes and territories for whom goals have not 
yet been established in the final EGs may be able to participate in the 
CEIP in the future.
    The EPA also requests comment on the proposed approach of requiring 
states to implement this program as a condition of a state choosing to 
determine its own allocation approach via a partial state plan or a 
delegation of the federal plan.

5. Allocations to Units That Change Status
    Units that retire. The EPA proposes that, if an affected EGU does 
not operate for 2 consecutive calendar years, the unit would continue 
to receive allocations for a limited number of years after it ceases 
operation, after which the allowances that would otherwise have been 
allocated to that unit would be allocated to the RE set-aside for the 
state in which the retired unit is located.\113\ Continuing allocations 
to non-operating units for a period of time reduces the incentive to 
keep a unit operating simply to avoid losing the allowance allocations 
for that unit (e.g., a unit that would otherwise be retired due to age 
and inefficiency). On the other hand, non-operating units are no longer 
emitting and so do not need allowances. The EPA believes that the 
proposed approach of allocating allowances for a specified, but 
limited, period after a unit ceases operating is a reasonable middle 
ground approach. The proposed approach also allows the RE set-asides to 
grow over time.
---------------------------------------------------------------------------

    \113\ This is similar to the approach taken in CSAPR of 
continuing allocations to retired units for four years and then 
allocating the allowances to a set-aside; in CSAPR the set-aside is 
for new units.
---------------------------------------------------------------------------

    The EPA proposes to record allowances for each year of a multi-year 
compliance period at once, 7 months prior to the start of each 
compliance period, as discussed above. The agency proposes that, if an 
affected EGU does not operate for 2 full calendar years, then starting 
with the next compliance

[[Page 65027]]

period for which allowances have not yet been recorded, the allowances 
that would otherwise have been allocated to the unit would be allocated 
to the RE set-aside. As a result, the number of years of non-operation 
for which a retired unit would receive allocations would vary depending 
on when a unit retires. For example, if an affected EGU does not 
operate for the first two calendar years of a 3-year compliance period, 
then starting with the next compliance period the allowances that would 
otherwise have been allocated to that unit would be allocated to the RE 
set-aside--in other words the unit would receive allocations for 3 
years of non-operation. As a further example, if an affected EGU does 
not operate for both calendar years of a 2-year compliance period, then 
starting with the compliance period after the next compliance period 
the allowances would be allocated to the RE set-aside--in other words 
the unit would receive allocations for 4 years of non-operation.
    The agency requests comment on this approach for treatment of 
allocations to affected EGUs that retire, including on the number of 
years of non-operation for which a unit would continue to receive 
allocations. The EPA also requests comment on an alternative of 
distributing such allowances to the set-aside for output-based 
allocations, or to the remaining affected EGUs in the state in a pro-
rata fashion (on the same distribution basis as the initial allocations 
were made), instead of allocating such allowances to the state's RE 
set-aside. The agency requests comment on a further alternative 
approach, which would be to continue allocations to the retired units. 
The EPA also requests comment on treatment of allocations to units that 
are in long-term cold storage.
    Units that are modified or reconstructed. Similar to the approach 
for an affected EGU that retires, the EPA proposes that, if a unit is 
modified or reconstructed such that it is no longer an affected EGU, 
then starting with the next compliance period for which allowances have 
not yet been recorded, the allowances that would otherwise have been 
allocated to the unit would be allocated to the RE set-aside. The EPA 
requests comment on this proposed approach, including on the number of 
years for which a unit would continue to receive allocations. The 
agency also requests comment on an alternative of distributing such 
allowances to the set-aside for output-based allocations, or to the 
remaining affected EGUs in the state in a pro-rata fashion (on the same 
distribution basis as the initial allocations were made), instead of 
allocating such allowances to the state's RE set-aside. The agency 
requests comment on a further alternative approach, which would be to 
continue allocations to the modified or reconstructed units.

E. State-Determined Allowance Distribution

    The EPA proposes to allow any state to replace the EPA-determined 
federal plan allowance-distribution provisions in the mass-based 
trading program with state-developed allowance-distribution provisions. 
In this way, a state could choose how to distribute initial allowance 
allocations among its affected EGUs (and other entities).
    The EPA believes that this option may offer significant appeal, 
because it will allow a state to tailor its allocation approach to the 
characteristics and preferences of the state. A state would be able to 
design its allocation approach to address its particular state 
priorities, whether they are protecting low-income consumers, 
supporting local industries, or other goals. The EPA anticipates that a 
state would have great flexibility in its allowance distribution 
approach and could take advantage of allocation options discussed in 
this proposal as well as other allocation options a state might prefer. 
States could auction allowances and rebate the revenue to consumers, or 
allocate all allowances to load-serving entities, while mandating that 
the value be passed through to vulnerable consumers. The EPA believes 
that the state-determined allocation approach offers significant 
advantages and solicits comment on how to ease its application by 
states. This is similar to the approach taken in CSAPR and CAIR where 
the EPA adopted rules allowing states to submit SIPs with provisions 
replacing the allowance-distribution provisions in the CSAPR or CAIR 
FIPs, respectively, while remaining in the trading programs under those 
FIPs (76 FR 48208; August 8, 2011, 71 FR 25328; April 28, 2006). In 
both CSAPR and CAIR, some states have chosen to determine their own 
allocations under the FIPs. This form of SIP that can replace the 
allowance-distribution provisions in CSAPR or CAIR is termed an 
``abbreviated SIP revision.'' In this proposed mass-based trading 
federal plan, the EPA proposes that a state may choose to submit a 
``state allowance-distribution methodology'' (analogous to an 
abbreviated SIP revision) to replace the federal plan allowance-
distribution provisions with allowance-distribution provisions of its 
choosing.
    The mechanism the agency envisions is in the nature of a partial 
state plan or (for any future changes in a state's allocation 
methodology) a partial state plan revision. (We request comment below 
on the advantages and disadvantages of allowing a state to handle 
allocations via a delegation of federal plan authority.) In general, 
under the proposed approach, the procedural requirements states and the 
agency must follow, including public notice requirements, for the 
submission and approval of state plans, would be required here.
    The EPA intends to provide the states with substantial flexibility 
in choosing approaches to distribute their allowances in a state 
allowance-distribution methodology. The EPA proposes that a state may 
choose any approach, including auctions or other methods the EPA is not 
proposing here, provided the state's approach addresses leakage and 
also implements the Clean Energy Incentive Program. The EPA is also 
requesting comment on any other appropriate constraints to impose on 
state allowance-distribution methodologies.
    The Clean Power Plan EGs require mass-based state plans to include 
a demonstration that they have addressed the risk of leakage, and the 
EGs provide several options for doing so (see sections VII.D and VIII.J 
of the final EGs). One of the options provided in the EGs is to address 
leakage through an allowance distribution approach that provides 
incentive to counteract leakage. In the mass-based trading federal 
plan, the EPA's proposed approach to allocate allowances would address 
leakage using two allowance set-asides, one for output based allocation 
and one for RE projects, as detailed in section V.D.3 of this preamble. 
The EPA believes that a state allowance-distribution methodology, which 
would replace the federal plan allocation provisions, must also address 
leakage. The EPA proposes that a state allowance-distribution 
methodology must address leakage by providing incentive to counteract 
leakage, e.g., by including allowance set-asides like the output-based 
allocation and RE set-asides detailed in section V.D.3 of this 
preamble, or other allocation approaches designed to counteract 
leakage. The EPA requests comment on this proposed approach for 
addressing leakage in a state allowance-distribution methodology and on 
any other approaches for doing so. The EGs provide an additional option 
for state plans to address leakage, where a state would provide a 
demonstration that leakage will not occur (without implementing any of 
the strategies specified in the EGs) due to specified

[[Page 65028]]

characteristics of the state (section VIII.J of the final EGs). In this 
federal plan proposal, the EPA requests comment on an alternative 
option where a state that chooses to submit a state allowance-
distribution methodology could provide a demonstration that leakage 
will not occur (without implementing the allocation strategies 
specified here) due to specific characteristics of the state; the EPA 
proposes that such demonstration must meet the requirements in the 
final EGs, including support by credible analysis, for such a 
demonstration (see final EGs section VII.D). The EPA notes that a 
state's allowance-distribution methodology may also include other set-
aside approaches that are not designed to counteract leakage.
    The Clean Power Plan EGs established a Clean Energy Incentive 
Program (section VIII of the final EGs). The EPA proposes that a state 
allowance-distribution methodology, which would replace the federal 
plan allocation provisions, must also include a Clean Energy Incentive 
Program, as detailed in section V.D.4 of this preamble.
    Under the proposed approach of providing for states to determine 
their allowance distribution approaches in the federal plan mass-based 
trading program, the affected EGUs in a state that submitted a state 
allowance-distribution methodology, which the EPA approved, would 
participate in the federal plan mass-based trading program, but with 
allowance distribution determined by the state instead of by the EPA.
    The EPA proposes that a state must submit to the Administrator 
tables specifying the unit-level allowances in an electronic format 
specified by the Administrator and by the specified deadlines 
applicable to each compliance period (see Table 11 of this preamble for 
proposed submission deadlines).
    The EPA proposes that a state may submit a state allocation 
methodology for any compliance period, including the first compliance 
period, which would comprise the years 2022, 2023, and 2024. The EPA 
proposes that a state submitting a state allowance-distribution 
methodology to modify the federal plan allowance-distribution 
provisions must do so for all years within a compliance period (e.g., 
for all 3 years in a 3-year compliance period).
    The EPA proposes that, if the state's allowance-distribution 
provisions meet certain requirements and the state allowance-
distribution methodology does not change any other provisions in the 
proposed mass-based trading program, then the agency would likely 
approve the state allowance-distribution methodology. In the state 
allowance-distribution methodology, the state could distribute 
allowances to affected EGUs or other entities (such as RE facilities) 
or could auction some or all of the allowances. The agency proposes 
that for EPA approval, the state allowance-distribution methodology 
provisions would have to meet the following requirements. The 
provisions would have to address leakage as discussed above. The 
provisions would have to provide that, for each year for which the 
state allowance-distribution provisions would apply, the total amount 
of allowances distributed could not exceed the applicable mass goal for 
that state for that year. A state's methodology under this proposed 
approach could provide that the total amount of allowances distributed 
is less than the applicable mass goal.\114\ The EPA proposes that a 
state's allowance-distribution provisions would replace the EPA's 
allocation provisions completely--a state would not have the option of 
implementing only a portion of its allocations (e.g., only set-asides) 
and having the EPA implement the remainder of its allocations. 
Additionally, the EPA proposes that a state allowance-distribution 
methodology must provide for allowances to be issued in short tons.
---------------------------------------------------------------------------

    \114\ A state allowance-distribution methodology under this 
proposed approach, which is analogous to an abbreviated SIP 
revision, could provide that the total amount of allowances 
distributed is less than the applicable mass goal, pursuant to the 
reserved authority to states to set emission standards more 
stringent than federal standards under CAA section 116.
---------------------------------------------------------------------------

    The allocation (or auction) of allowances would be final and could 
not be subject to modification. Additionally, the state's provisions 
could not change any other provisions of the proposed mass-based 
trading program with regard to the allowances (e.g., the deadlines for 
allocation recordation, or requirements for transfer or use of 
allowances) or any other aspect of such trading programs.
    In order for a state allowance-distribution methodology's 
provisions to replace the EPA's allowance-distribution provisions for a 
given compliance period, a state would have to submit the state 
allowance-distribution methodology by a deadline that would provide the 
agency sufficient time to review and approve it, and to submit the 
allowance table meeting the specified electronic format by a deadline 
that would provide sufficient time to record the unit-by-unit 
allowances in source accounts. The EPA believes that about 12 months--
starting from the date of receipt of a state allowance-distribution 
methodology--is sufficient to complete the agency's review and approval 
process, which would have to provide an opportunity for public comment 
on the approval (or disapproval) action. Thus, the EPA proposes the 
following deadlines, in Table 11 of this preamble, for submission to 
the agency of state allowance-distribution methodologies and unit-level 
allowances, and for the EPA's recordation of allowances, for each 
compliance period. The EPA would review and approve state allowance-
distribution methodologies in the 12 months between the proposed 
deadline for states to submit their methodologies and the proposed 
deadline for states to submit unit-level allowance tables. The proposed 
deadline for submission of allowance tables is 3 months before the 
proposed deadline for the agency to record allowances in source 
accounts. The EPA proposes to record allowances in source accounts by 
the recordation deadlines.

    Table 11--Proposed Deadlines for Submission of State Allowance-Distribution Methodologies and Unit-Level
                                         Allowances and for Recordation

----------------------------------------------------------------------------------------------------------------
* This pattern of deadlines would hold for successive 2-year compliance periods.


[[Page 65029]]

    The proposed deadlines for submission of state allowance-
distribution methodologies are later than the state plan submission 
deadlines promulgated in the Clean Power Plan EGs. The agency 
anticipates that it can complete the approval process relatively 
quickly for a state allowance-distribution methodology due to its 
narrow scope.
    The agency proposes to record the EPA-determined federal plan 
allocations only in the absence of an approved state plan or approved 
state allowance-distribution methodology. The EPA proposes to record in 
source accounts allowances that are determined by any state as soon as 
feasible after approval of a state allowance-distribution methodology 
and submission of the unit-level allowance table, and not to wait until 
the allowance recordation deadline to do so.
    In section V.D.2 of this preamble, the EPA proposes that the 
allowance recordation deadline be 7 months prior to the start of the 
compliance period (i.e., June 1 of the prior year) and also requests 
comment on a recordation deadline 13 months prior to the start of the 
compliance period (i.e., December 1 of the year, 2 years before the 
compliance period starts). If the EPA adopted the earlier recordation 
deadline on which it requests comment or any other deadline, then we 
would adjust the deadlines for submission of state allowance-
distribution methodologies and submission of unit-level allowance 
tables accordingly.
    The EPA proposes that a state may not replace EPA-determined 
allocations for a compliance period for which federal plan allocations 
have already been recorded, for the same reasons that the agency 
proposes that a state may not replace a mass-based trading federal plan 
with a state plan for a future compliance period for which allowances 
have already been recorded, as discussed below in section V.F of this 
preamble.
    The agency requests comment on the proposed approach to allow 
states to determine allocations via state allowance-distribution 
methodologies and replace the federal plan allowance-distribution 
provisions. The EPA requests comment on the proposed schedule for 
submitting state allowance distribution methodologies to the agency, 
for submitting the resulting unit-level allowance tables to the agency, 
and for the agency to record allowances. The EPA requests comment on 
its proposed approach of not replacing EPA-determined allocations for a 
compliance period for which allowances have already been recorded. The 
agency also requests comment on an alternative approach where a state 
could notify the EPA of its intent to submit a state allowance-
distribution methodology in advance, in which case the agency would 
hold off on recording EPA-determined allocations to allow more time for 
state-determined allowances to be recorded, similar to the alternative 
timing approach discussed in section V.F of this preamble.
    The EPA is also requesting comment on an alternative approach to 
provide the opportunity for a state to determine its allowance-
distribution provisions in the federal plan mass-based trading program. 
The alternative approach on which the agency requests comment is to 
provide for a partial delegation of the federal plan--limited to the 
allowance-distribution provisions--to a state that wishes to determine 
its allowance-distribution provisions. The EPA requests comment on the 
relative efficiency and ease of implementation of the two approaches 
(the state allowance-distribution methodology described above, or the 
partial delegation). The agency requests comment on whether the partial 
delegation approach would provide sufficient flexibility for a state to 
choose any method to distribute its allowances including approaches 
that the EPA is not proposing here. See further discussion of 
delegations in section VI of this preamble.

F. Treatment of States Entering or Exiting the Trading Program

    If the EPA implements a mass-based trading program federal plan for 
any state, the agency will work with a state that wishes to replace the 
federal plan with an approved state plan to provide a smooth 
transition. The EPA proposes that a mass-based trading federal plan 
could only be replaced by a state plan for a future compliance period 
for which allowances have not yet been recorded. For example, if a 3-
year compliance period comprises 2022, 2023, and 2024, the EPA would 
record allowances in source accounts for 2022, 2023, and 2024 prior to 
2022. Once 2022, 2023, and 2024 allowances had been recorded, the first 
compliance period for which a state could replace the federal plan with 
its own plan would be for the period commencing in 2025. The EPA is 
proposing this stipulation for the timing of replacing a federal plan 
with a state plan due to the need to avoid disruption to sources 
already subject to the mass-based trading federal plan. Without this 
stipulation, a state might withdraw from the mass-based trading program 
in the middle of a compliance period even though allowances that 
authorize emissions throughout that entire compliance period would 
already be in circulation. In that circumstance, the EPA would then 
need to address whether and how to remove those allowances from 
circulation to prevent inflation of the allowable emissions at affected 
EGUs in the remaining states subject to the federal plans beyond the 
levels specified in the Clean Power Plan EGs. The EPA believes it is 
more reasonable to avoid this potential disruption by requiring that 
the replacement of a federal plan with a state plan be scheduled to 
coincide with the conclusion of the last compliance period for which 
allowances under the federal plan have already been recorded for that 
state. The EPA requests comment on other approaches to provide a smooth 
transition from federal plan implementation to implementation by state 
plans, and on its proposed approach of not replacing a federal plan for 
any compliance period for which allowances were already recorded.
    The agency requests comment on an alternative of providing for a 
state to give notice to the EPA of its intent to submit a state plan to 
replace the federal plan (or a state allowance-distribution methodology 
to replace federal plan allocations), and for the agency to delay 
recording federal plan allocations for sources in that state until a 
later date than proposed. The EPA requests comment on whether this 
alternative would help smooth the transition from federal plan 
implementation to state plan implementation, and on the trade-off 
between recording allowances in a timely way and providing this 
increased timing flexibility.

G. Allowance Tracking, Compliance Operations, and Penalties

    The EPA proposes that the mass-based trading program use an ATCS 
operated essentially the same way as the existing systems that are 
currently in use for CSAPR and the ARP under Title IV. Under the 
proposed mass-based trading program, the CO2 program would 
be a separate trading program maintained in the EPA's existing data 
system. ATCS would be used to track the trading of CO2 
allowances held by covered affected EGUs in facility level compliance 
accounts, as well as such allowances held by other entities or 
individuals. Specifically, ATCS would track the allocation of all 
CO2 allowances, holdings of CO2 allowances in 
compliance accounts (i.e., a facility level account for all affected 
EGUs at the facility) and general accounts (i.e., accounts for other 
entities such as companies and brokers), deduction of CO2 
allowances for compliance

[[Page 65030]]

purposes, and transfers of allowances between accounts. The primary 
role of ATCS is to provide an efficient, automated means for affected 
EGUs to comply, and for the EPA to determine whether affected EGUs are 
complying, with the emissions limitations and any other requirements of 
the mass-based trading program. ATCS would also provide data to the 
allowance market and the public, including a record of ownership of 
allowances, dates of allowance allocations, allowance transfers, buyer 
and seller information, serial numbers of allowances transferred, 
emissions, and compliance information. This information would be 
publicly available on the EPA's Web site and in annual progress 
reports.
1. Designated Representatives and Alternate Designated Representatives
    The EPA proposes to establish procedures for certifying and 
authorizing the designated representative, and alternate designated 
representative, of the owners and operators of an affected EGU and for 
changing the designated representative and alternate designated 
representative. The proposed provisions describe the designated 
representative's and alternate designated representative's 
responsibilities and the process through which he or she could delegate 
to an agent the authority to make electronic submissions to the 
Administrator. These provisions are patterned after the provisions 
concerning designated representatives and alternates in prior EPA-
administered trading programs.
    Under the proposed provisions, the designated representative would 
be the individual authorized to represent the owners and operators of 
each affected EGU in matters pertaining to the mass-based trading 
program. One alternate designated representative could also be selected 
to act on behalf of, and legally bind, the designated representative 
and thus the owners and operators. Because the actions of the 
designated representative and alternate would legally bind the owners 
and operators, the designated representative and alternate would have 
to submit a certificate of representation certifying that each was 
selected by an agreement binding on all such owners and operators and 
was authorized to act on their behalf.
    The designated representative and alternate would be authorized 
upon receipt by the Administrator of the certificate of representation. 
This document, in a format prescribed by the Administrator, would 
include: Specified identifying information for the affected EGU and for 
the designated representative and alternate; the name of every owner 
and operator of the affected EGU; and certification language and 
signatures of the designated representative and alternate. All 
submissions (e.g., monitoring plans, monitoring system certifications, 
and allowance transfers) for an affected EGU would have to be 
submitted, signed, and certified by the designated representative or 
alternate. Further, upon receipt of a complete certificate of 
representation, the Administrator would establish a compliance account 
in the ATCS for each facility with an affected EGU involved.
    In order to change the designated representative or alternate, a 
new certificate of representation would have to be received by the 
Administrator. A new certificate of representation would also have to 
be submitted to reflect changes in the owners and operators of the 
affected EGU involved. However, new owners and operators would be bound 
by the existing certificate of representation even in the absence of 
such a submission.
    In addition to the flexibility provided by allowing an alternate to 
act for the designated representative (e.g., in circumstances where the 
designated representative might be unavailable), additional flexibility 
would be provided by allowing the designated representative and 
alternate to delegate authority to make electronic submissions on his 
or her behalf. The designated representative and alternate could 
designate agents to submit electronically certain specified documents. 
The previously-described requirements for designated representatives 
and alternates would provide regulated entities with flexibility in 
assigning responsibilities under the mass-based trading program, while 
ensuring accountability by owners and operators and simplifying the 
administration of the proposed mass-based trading program.
2. Allowance Tracking and Compliance System
    The proposed mass-based trading program rules include procedures 
and requirements for using and operating the ATCS (which is the 
electronic data system through which the Administrator would handle 
allowance allocation, holding, transfer, and deduction), and for 
determining compliance with the allowance-holding requirements in an 
efficient and transparent manner. Under the proposed rules, the ATCS 
would also provide the allowance markets with a record of ownership of 
allowances, dates of allowance transfers, buyer and seller information, 
and the serial numbers of allowances transferred. Consistent with the 
approach in prior EPA-administered trading programs, allowance price 
information would not be included in the ATCS. The EPA's experience is 
that private parties (e.g., brokers) are in a better position to obtain 
and disseminate timely, accurate allowance price information than is 
the EPA. For example, because not all allowance transfers are 
immediately reported to the Administrator for recordation, the 
Administrator would not be able to ensure that any reported price 
information associated with the transfers would reflect current market 
prices.
3. Compliance and General Accounts
    The proposed provisions addressing compliance and general accounts 
describe two types of ATCS accounts: Compliance accounts, one of which 
the Administrator would establish for each facility with an affected 
EGU upon receipt of the certificate of representation for the facility; 
and general accounts, which could be established by any entity upon 
receipt by the Administrator of an application for a general account. A 
compliance account would be the account in which any allowances used by 
an affected EGU for compliance with the emissions limitations would 
have to be held. The designated representative and alternate for the 
affected EGU would also be the authorized account representative and 
alternate for the compliance account. Using facility-level, rather than 
EGU-level accounts, would provide owners and operators more flexibility 
in managing their allowances for compliance, without jeopardizing the 
environmental goals of the mass-based trading program, because the 
facility-level approach would avoid situations where an EGU would hold 
insufficient allowances and would be in violation of allowance-holding 
requirements even though EGUs at the same facility had more than enough 
allowances to meet these requirements for the entire facility. 
Facility-level compliance would also be consistent with other EPA-
administered mass-based trading programs.
    General accounts could be used by any person or group for holding 
or trading allowances. However, allowances could not be used for 
compliance with emissions limitations so long as the allowances were 
held in, and not properly and timely transferred out of, a general 
account. To open a general account, a person or group would have to 
submit an application for a general account, which would be

[[Page 65031]]

similar in many ways to a certificate of representation. The 
application would include, in a format prescribed by the Administrator: 
The name and identifying information of the individual who would be the 
authorized account representative and of any individual who would be 
the alternate authorized account representative; an identifying name 
for the account; the names of all persons with an ownership interest 
with respect to allowances held in the account; and certification 
language and signatures of the authorized account representative and 
alternate. The authorized account representative and alternate would be 
authorized upon receipt of the application by the Administrator. The 
provisions for changing the authorized account representative and 
alternate, for changing the application to take account of changes in 
the persons having an ownership interest with respect to allowances, 
and for delegating authority to make electronic submissions would be 
analogous to those applicable to comparable matters for designated 
representatives and alternates.
4. Recordation of Allowance Allocations and Transfers
    The EPA proposes to establish the following schedule and procedures 
for recordation of allowance allocations and transfers. By June 1, 
2021, the Administrator would record allowance allocations for EGUs for 
2022 through 2024. Then, by June 1 of the year prior to the beginning 
of each compliance period, the Administrator would record the allowance 
allocations for the proposed mass-based trading program for each year 
within that next compliance period, e.g., for 2025, 2026, and 2027 by 
June 1, 2024. Recording these allowance allocations in advance of the 
first year for which they could be used for compliance would facilitate 
compliance planning by owners and operators and promote robust 
allowance markets, including futures markets for allowances.
    Under the proposed provisions, the process for transferring 
allowances from one account to another would be quite simple. 
Allowances could be transferred by submitting a transfer form 
providing, in a format prescribed by the Administrator, the account 
numbers of the accounts involved, the serial numbers of the allowances 
involved, and the name and signature of the transferring authorized 
account representative or alternate. If a transfer form containing all 
the required information were submitted to the Administrator and, when 
the Administrator attempted to record the transfer, the transferor 
account included the allowances identified in the form, the 
Administrator would record the transfer by moving the allowances from 
the transferor account to the transferee account within 5 business days 
of the receipt of the transfer form.
5. Compliance With Emissions Limitations
    The EPA proposes to include the following provisions regarding 
compliance with emission limitations. Under the proposed provisions, 
once the compliance period has ended (e.g., at midnight on December 31, 
2024 for the first compliance period), facilities with affected EGUs 
would have a window of opportunity following the compliance period to 
evaluate their reported emissions and obtain any allowances that they 
might need to cover their emissions during the compliance period. For 
example, the allowance transfer deadline for the first compliance 
period would be midnight on May 1, 2025 (the EPA is also requesting 
comment on earlier or later allowance transfer deadlines). Each 
allowance issued in the proposed mass-based trading program would 
authorize emission of one ton of CO2 and so would be usable 
for compliance, for the compliance period that includes the year for 
which the allowance was allocated or a later compliance period. 
Consequently, each affected EGU would need, as of the allowance 
transfer deadline, to have in its facility compliance account, or to 
have a properly submitted transfer that would move into its compliance 
account, enough allowances usable for compliance to authorize its total 
emissions for the compliance period. The authorized account 
representative could identify specific allowances to be deducted, but, 
in the absence of such identification or in the case of a partial 
identification, the Administrator would deduct on a first-in, first-out 
basis. Deducting allowances may have tax and accounting implications, 
so having a default deduction method provides the representatives with 
certainty regarding which allowances will be deducted for compliance. 
Allowances that are deducted for compliance will remain in the system 
in an EPA account, which ensures they will not be used again. If a 
facility were to fail to hold sufficient allowances for compliance by 
all affected EGUs at the facility, then the owners and operators of the 
facility and each affected EGU at the facility would have to provide, 
for deduction by the Administrator, two allowances allocated for the 
compliance period in the next year for every allowance that the owners 
and operators failed to hold as required to cover emissions. This 
submittal of two times the allowances required for the prior period is 
an ongoing obligation until compliance is achieved, and there is an 
ongoing obligation to comply in the current period. In addition, these 
owners and operators would be subject to civil penalties for each 
violation in accordance with the CAA, with each ton of unauthorized 
emissions and each day of the compliance period involved constituting a 
violation of the CAA.
    The EPA believes that it is important to include a requirement for 
an automatic deduction of allowances. The deduction of one allowance 
per allowance that the owners and operators failed to hold would offset 
this failure. The automatic deduction of another allowance per 
allowance that the owners and operators failed to hold that could not 
be avoided, regardless of any explanation provided by the owners and 
operators for their failure, would provide a strong incentive for 
compliance with the allowance-holding requirement by ensuring that non-
compliance would be a significantly more expensive option than 
compliance. Such automatic deductions have been successfully used in 
prior programs including the CAIR, achieving compliance rates close to 
100 percent.
6. Other Allowance Tracking and Compliance Operations Provisions
    The proposed provisions regarding allowance tracking and compliance 
also provide that the Administrator could, at his or her discretion and 
on his or her own motion, correct any type of error that he or she 
finds in an account in the ATCS. In addition, the Administrator could 
review any submission under the mass-based trading program, make 
adjustments to the information in the submission, and deduct or 
transfer allowances based on such adjusted information. These 
provisions are a standard part of other trading programs administered 
by the EPA including the ARP and Cross State Air Pollution Rule (see 40 
CFR 72.96, 73.37, 97.427, and 97.428).

H. Emissions Monitoring and Reporting Requirements

    The EPA proposes that units subject to the mass-based federal plan 
trading program would monitor and report CO2 mass emissions 
in accordance with 40 CFR part 75.
    The EPA is proposing to require affected EGUs in all states covered 
by the mass-based federal plan trading program to monitor and report 
CO2 emissions and output data by January 1, 2022. Quarterly 
reporting would be

[[Page 65032]]

required, with each quarterly report due to the Administrator 30 days 
after the last day in the quarter. The reporting would be in accordance 
with 40 CFR 75.60. The use of 40 CFR part 75 certified monitoring 
methodologies would be required. Many EGUs that might be covered by the 
proposed federal plans will generally have no changes to their 
monitoring and reporting requirements and will continue to monitor and 
submit reports under 40 CFR part 75 as they have under existing 
programs. The EPA anticipates fewer than 50 affected EGUs that would 
not otherwise be subject to the ARP will have to purchase and install 
additional CEMS and data handling systems or upgrade existing equipment 
in order to meet the monitoring and reporting requirements of this 
program (the EPA anticipates approximately 10 coal fired units and 
approximately 40 gas and oil fired units will qualify for an excepted 
monitoring methodology). Several of the units not otherwise subject to 
the ARP are subject to the MATS program and, therefore, will have 
already installed stack flow rate and/or CO2 monitors 
necessary to comply with this rule in order to comply with the MATS. 
The CEMS used to comply and report data for MATS will be used for this 
rule to generate and report CO2 emissions data without 
having to install duplicative monitors. The same CO2 and 
stack gas flow rate monitored data used in conjunction with mercury and 
other CEMS to calculate a toxic pollutant emission rate may be used to 
calculate a CO2 mass or CO2 emission rate for 
this program. RGGI, ARP, MATS and this rule all refer to CEMS installed 
and certified in accordance with 40 CFR part 75. RGGI and ARP currently 
require the reporting of CO2 mass emissions on an hourly 
basis and cumulative totals at the end of each calendar quarter. The 
same monitors and data collected may be used for multiple purposes for 
RGGI, ARP, MATS and this rule. Relying on the same monitors that are 
certified and quality ensured in accordance with 40 CFR part 75 ensures 
cost efficient, consistent, and accurate data that may be used for 
different purposes for multiple regulatory programs.
    The majority of the units covered by this rule are already affected 
by the Acid Rain and/or RGGI programs and will have minimal additional 
monitoring and reporting requirements.
    The EPA also requests comment on requiring monitoring and reporting 
of CO2 mass and net generation for the year before the 
initial compliance period begins, i.e., to commence January 1, 2021. 
Only the monitoring and reporting would be required in 2021--compliance 
with the requirement to hold allowances would commence on the 
compliance period schedule that is detailed in section V.C of this 
preamble.

VI. Implementation of the Federal Plan and Delegation

    Under section 111(d) of the CAA, the EPA adopts EGs that are then 
implemented when the EPA approves a state or tribal \115\ plan or 
promulgates a federal plan that implements and enforces the EGs for 
affected EGUs in states or areas of Indian country \116\ without an 
approved state or tribal plan. Congress has determined that the primary 
responsibility for air pollution prevention and control rests with 
state and local agencies, while also recognizing that federal 
leadership is essential for the development of cooperative federal, 
state, regional, and local programs to prevent and control air 
pollution. See CAA section 101(a)(3) and (4). Congress has also 
provided for Indian Tribes meeting specified eligibility criteria to 
implement the CAA within the exterior boundaries of their reservations 
or other areas within the tribe's jurisdiction. See CAA section 
301(d)(1) and (2). Even in the event that it becomes necessary for the 
EPA to directly regulate affected EGUs under CAA section 111(d), states 
and eligible tribes may still seek a delegation of authority from the 
EPA to implement a federal plan, similar to the ability to take 
delegated authority under other CAA programs. The EPA encourages states 
and eligible tribes that do not submit approvable plans to request 
delegation of the federal plan if they wish to have primary 
responsibility for implementing the EGs. Approved and effective state 
or tribal plans or delegation of the federal plan is the EPA's 
preferred outcome in many circumstances where the EPA believes that 
state and local, or tribal, agencies have practical knowledge and 
enforcement resources critical to achieving the highest rate of 
compliance. Delegation of a standard or requirement generally means 
that obligations a source may have to the EPA under a federally 
promulgated standard become obligations to a state or tribe in the 
first instance (except for functions that the EPA retains for itself) 
upon delegation.117 118
---------------------------------------------------------------------------

    \115\ As discussed in section VI.D of this preamble, tribes with 
affected EGUs in their areas of Indian country can apply for TAS for 
the purpose of developing and seeking EPA approval of a tribal 
implementation plan (TIP) implementing the EG, but are not required 
to do so.
    \116\ As discussed in section VI.D of this preamble, in adopting 
a federal plan implementing the EGs in areas of Indian country 
containing affected EGUs, the EPA must determine that such a plan is 
``necessary or appropriate'' to protect air quality. See 40 CFR 
49.11(a).
    \117\ If the Administrator chooses to retain certain authorities 
under a standard, those authorities cannot be delegated, e.g., the 
authority to allow alternative methods of demonstrating compliance.
    \118\ We note that issuance of a title V permit is not 
equivalent to the approval of a state plan or delegation of a 
federal plan. This has been discussed in prior rulemakings, see, 
e.g., Proposed Federal Plan for Commercial Industrial Solid Waste 
Incinerators (CISWI) (67 FR 70640, 70652; November 25, 2002); Final 
Federal Plan for CISWI (68 FR 57518, 57535; October 3, 2003).
---------------------------------------------------------------------------

A. Delegation of the Federal Plan and Retained Authorities

    If a state or tribe \119\ intends to take delegation of the federal 
plan, the state or tribe should submit to the appropriate EPA Regional 
Office a written request for delegation of authority. The state or 
tribe should explain how it meets the criteria for delegation. These 
criteria are explainedgenerally in the ``Good Practices Manual for 
Delegation of NSPS and NESHAP'' (EPA, February 1983). The letter 
requesting delegation of authority to implement the federal plan 
should: (1) Demonstrate that the state or tribe has adequate resources, 
as well as the legal and enforcement authority to administer and 
enforce the program; (2) include an inventory of affected EGUs, which 
includes those that have ceased operation but have not been dismantled, 
an inventory of the affected units' air emissions, and a provision for 
state or tribal progress reports to the EPA; (3) certify that a public 
hearing has been held on the state or tribal delegation request; and 
(4) include a memorandum of agreement between the state or tribe and 
the EPA that sets forth the terms and conditions of the delegation, the 
effective date of the agreement and the mechanism to transfer 
authority. Upon signature of the agreement, the appropriate EPA 
Regional Office would publish an approval documentin the Federal 
Register, thereby incorporating the delegation of authority into the 
appropriate subpart of 40 CFR part 62. See also EPA's Delegations 
Manual, Delegation 7-139, ``Implementation and Enforcement of 111(d)(2) 
and 111(d)(2)/129(b)(3) federal plans.'' (A copy of this delegation has 
been placed in the docket for this action.)
---------------------------------------------------------------------------

    \119\ A tribe interested in taking delegation of the federal 
plan must also apply, and be approved by the EPA, for TAS 
eligibility for that purpose. See 40 CFR part 49.
---------------------------------------------------------------------------

    If authority is not delegated to a state or tribe, the EPA will 
implement the federal plan. Also, if a state or tribe fails to properly 
implement a delegated portion of the federal plan, the EPA will assume 
direct implementation and

[[Page 65033]]

enforcement of that portion. The EPA will continue to hold inspection, 
information gathering, enforcement, and other parallel authorities 
along with the state or tribe even when a state or tribe has received 
delegation of the federal plan. In all cases where the federal plan is 
delegated, the EPA may retain and not transfer authority to a state or 
tribe to approve certain items promulgated in the 2015 CAA section 
111(d) Clean Power Plan.
    This proposed federal plan also specifies that EGU owners or 
operators who wish to petition the agency for any alternative 
requirement should submit a request to the Regional Administrator with 
a copy sent to the appropriate state.

B. Mechanisms for Transferring Authority

    There are two mechanisms for transferring implementation authority 
to state and local agencies and tribes: (1) EPA approval of a state or 
tribal plan after the federal plan is in effect; and (2) if a state or 
tribe does not submit or obtain approval of its own plan, EPA 
delegation to a state or tribe of the authority to implement certain 
portions of this federal plan to the extent appropriate and if allowed 
by state or tribal law. Both of these options are described in more 
detail below.
1. Federal Plan Becomes Effective Prior To Approval of a State or 
Tribal Plan
    After EGUs in a state or area of Indian country become subject to 
the federal plan, the state or local agency or tribe may still adopt 
and submit a plan to the EPA. If the EPA determines that the state or 
tribal plan is satisfactory and approvable pursuant to the EGs, the EPA 
will approve the state or tribal plan. If the EPA, on review of the 
submitted state or tribal plan, determines that this is not the case, 
the EPA will disapprove the plan and the EGUs covered in the state or 
tribal plan would remain subject to the federal plan until a state or 
tribal plan covering those EGUs is approved and effective. Prior to 
disapproval, the EPA will work with states and eligible tribes to 
attempt to reconcile areas of the plan that are unapprovable.
    Upon the effective date of an approved state or tribal plan, the 
federal plan would no longer apply to EGUs covered by such a plan and 
the state or local agency, or the tribe, would implement and enforce 
the state or tribal plan in lieu of the federal plan. The timing of 
effectiveness of an approved state or tribal plan in this circumstance 
may depend in part on the need to ensure a smooth transition and 
maintain regulatory certainty. Thus, for example, under a mass-based 
federal plan, we propose to handle these transitions so that they 
coincide with the compliance periods. The approval of a state or tribal 
plan would also involve a public comment process, which would give 
interested stakeholders including any affected EGUs, the opportunity to 
comment. This will assist in ensuring that compliance, program 
integrity, electric reliability, and other critical factors are 
maintained. When an EPA Regional Office approves a state or tribal 
plan, it will amend the appropriate subpart of 40 CFR part 62 or 40 CFR 
part 49, respectively, to indicate such approval, as well as the timing 
of its effectiveness.
    As discussed elsewhere in this document, the EPA may also in 
certain circumstances approve a partial state or tribal plan (sometimes 
called an ``abbreviated state plan'') that may modify certain limited 
provisions in the federal plan trading program. For example, this could 
occur if a state or tribe wishes to handle the initial allocation of 
allowances in a mass-based trading program, as discussed in section V.E 
of this preamble. The partial state or tribal plan would allow for the 
state or tribe to assume direct authority for administering and 
implementing this aspect of the trading program, while the remainder of 
the federal plan remains in place. The procedural and submission 
requirements set forth in the framework regulations of 40 CFR part 60, 
subpart B and the EGs would generally apply to a partial state or 
tribal plan, just as they would a full state or tribal plan. The scope 
of the requirement, however, would be commensurate with the scope of 
the partial plan. For instance, if a state or tribe seeks approval of a 
partial plan solely to handle allowance allocations, then the required 
statement of legal authority would be limited to those legal 
authorities the state or tribe must have to implement and enforce this 
component of the trading program.
2. State or Tribe Takes Delegation of the Federal Plan
    The EPA, in its discretion, may delegate to state or tribal air 
agencies the authority to implement this federal plan. As discussed 
above, the EPA believes that it is advantageous and the best use of 
resources for state or local agencies or tribes to agree to undertake, 
on the EPA's behalf, administrative and substantive roles in 
implementing the federal plan to the extent appropriate and where 
authorized by state or tribal law. If a state or tribe requests 
delegation, the EPA will generally delegate the entire federal plan to 
the state or tribal agency, thereby providing authority to the state or 
tribe for things such as administration and oversight of compliance 
reporting and recordkeeping requirements, inspections of its affected 
EGUs, and enforcement. The EPA will continue to hold inspection, 
information gathering, enforcement, and other authorities along with 
the state or tribe even when a state or tribe has received delegation 
of the federal plan. The delegation will not include any authorities 
retained by the EPA.

C. Implementing Authority

    The EPA Regional Administrators have been delegated the authority 
for implementing the federal plan. All reports required by the federal 
plan should be submitted to the appropriate Regional Administrator. 
Section II.B of this preamble includes Table 2 that lists names and 
addresses of the EPA Regional Office contacts and the states they 
cover.
    With respect to the administration of a federal trading program in 
any final federal plan for a state or tribe, group of states or 
combined group of states and tribes, the Office of Air and Radiation 
within the Headquarters of the EPA is proposed to be the primary office 
within the agency with delegated CAA section 111(d)(2) authority. See 
Delegation 7-139, section 3(c).

D. Necessary or Appropriate Finding for Affected EGUs in Indian Country

    Indian Tribes may, but are not required to, submit tribal plans to 
implement the EGs. Section 301(d) of the CAA and 40 CFR part 49 
authorize the Administrator to treat an Indian Tribe in the same manner 
as a state (i.e., TAS) for purposes of developing and implementing a 
tribal plan implementing the EGs. See 40 CFR 49.3; see also ``Indian 
Tribes: Air Quality Planning and Management,'' hereafter ``Tribal 
Authority Rule,'' (63 FR 7254, February 12, 1998). We invite tribes 
with EGU in their area of Indian country to comment on the level of 
their interest, if any, in developing their own plans.
    The EPA is proposing in this action to find that it is necessary or 
appropriate to regulate affected EGUs in each of the three areas of 
Indian country that have affected EGUs under the proposed federal plan. 
The EPA is authorized to directly implement the EGs in Indian country 
when it finds, consistent with the authority of CAA section 301 which 
the EPA has exercised in 40 CFR 49.11, that it is necessary or 
appropriate to do so. In the final EGs, the EPA establishes emission 
performance rates for the four EGUs located in Indian country and

[[Page 65034]]

mass- and rate-based emission goals for each of the three affected 
areas of Indian country. These areas include lands of the Navajo 
Nation's reservation, lands of the Ute Tribe of the Uintah and Ouray 
Reservation, and lands of the Fort Mojave Tribe's reservation. The EPA 
proposed carbon pollution EGs for EGUs in these areas and U.S. 
Territories in a Supplemental Notice of Proposed Rulemaking. See 79 FR 
65482 (November 4, 2014). The four facilities with affected EGUs 
located in Indian country that the EPA identified in the Supplemental 
Notice are: The South Point Energy Center, on the Fort Mojave 
Reservation geographically located within Arizona; the Navajo 
Generating Station, on the Navajo Indian Reservation geographically 
located within Arizona; the Four Corners Power Plant, on the Navajo 
Indian Reservation geographically located within New Mexico; and the 
Bonanza Power Plant, on the Uintah and Ouray Indian Reservation 
geographically located within Utah. The emission performance targets 
for these areas were finalized along with those for EGUs located in the 
rest of the country in the final EGs.
    In this action, we are proposing to find that it is necessary or 
appropriate, in each of the three areas of Indian country that have 
affected EGUs, to establish a federal plan that applies to the four 
power plants located on the Navajo Nation, the Fort Mojave Indian 
Reservation, and the Uintah and Ouray Reservation of the Ute Tribe. The 
affected EGUs located on the Navajo Nation are in an area of Indian 
country located within the continental United States, are 
interconnected with the western electricity grid, and are owned and 
operated by entities that generate and provide electricity to customers 
in several states. The affected EGU located on the Uintah and Ouray 
Reservation of the Ute Tribe is in an area of Indian country located 
within the continental United States, is interconnected with the 
western electricity grid, and is owned and operated by an entity that 
generates and provides electricity to customers in several states. The 
affected EGU located on the Fort Mojave Indian Reservation is in an 
area of Indian country located within the continental United States, is 
interconnected with the western electricity grid, and is owned and 
operated by an entity that generates and provides electricity to 
customers in several states. To date, none of the three tribes on whose 
areas of Indian country the four power plants are located have 
expressed a clear intent to develop and seek approval of a tribal 
implementation plan. Thus, absent a federal plan, the significant 
emissions from these four power plants could go unregulated by the 
Clean Power Plan.
    Because the agency has finalized emission performance targets for 
these power plants in the EGs, there is, in our view, little benefit to 
be had by not proposing to include them in a federal plan now and a 
potentially significant downside to not doing so; the reductions the 
EPA has determined are achievable in the EGs would become more 
difficult and costly for these power plants to achieve if they are 
delayed in entering into the trading program the agency intends to 
establish. In order to meet the performance targets, we are 
anticipating that the affected EGUs may need to secure allowances or 
ERCs (depending on the approach ultimately finalized) during the 
compliance periods. They may also be able to generate and sell 
compliance instruments by participating in the trading program. Thus, 
proposing a finding that it is necessary or appropriate to establish 
one or more federal plans providing the ability to participate in a 
rate- or mass-based trading program is in the interest of these four 
power plants located in areas of Indian country. We believe that this 
together with the facts that, as indicated above, all four EGU are 
interconnected with the western electricity grid and are owned and 
operated by an entity that generates and provides electricity to 
customers in several states thereby making it potentially disruptive 
and inequitable not to include them in one or more federal plans on the 
same schedule as other affected EGU strongly supports proposing to find 
that it is necessary or appropriate to establish one or more applicable 
federal plans at this time.
    We recognize that the governments of these tribes may still choose 
to seek TAS to develop a tribal plan, and this proposed determination 
does not preclude the tribes from taking such actions. We also note 
that this proposed determination does not preclude these tribes from 
seeking TAS and receiving delegation to administer aspects of any 
applicable federal plan that is ultimately promulgated. In the event a 
federal plan is needed, proposing a necessary or appropriate finding at 
this time will allow the EPA to expeditiously promulgate a final 
federal plan for one or all of these power plants in the future to 
allow trading to occur. We will continue to consult with the 
governments of the Navajo Nation, Fort Mojave Indian Tribe, and the Ute 
Tribe of the Uintah and Ouray Reservation during the comment period for 
this proposal, and prior to taking any action to finalize a necessary 
or appropriate finding and/or a federal plan. Comments on the 
appropriateness of the proposed finding should be submitted within the 
comment period specified in the DATES section of this preamble.

VII. Amendments To Process for Submittal and Approval of State Plans 
and EPA Actions

    As indicated in the final rulemaking action for the CAA section 
111(d) guideline, ``Carbon Pollution Emission Guidelines for Existing 
Stationary Sources: Electric Utility Generating Units,'' in this 
action, in addition to the proposed federal plans and model trading 
rules, the EPA is also proposing to amend the framework regulations and 
update the process for acting on CAA section 111(d) state plans under 
40 CFR part 60, subpart B. These changes would be applicable to any 
future CAA section 111(d) rules going forward, not just the Clean Power 
Plan EGs. The EPA proposes six changes to the CAA section 111(d) 
process in the framework regulations to include: (1) Partial approval/
disapproval mechanisms similar to CAA section 110(k)(3); (2) a 
conditional approval mechanism similar to CAA section 110(k)(4); (3) a 
mechanism for the EPA to make calls for plan revisions similar to the 
``SIP-call'' provisions of CAA section 110(k)(5); (4) an error 
correction mechanism similar to CAA section 110(k)(6); (5) completeness 
criteria and a process for determining completeness of state plans and 
submittals similar to CAA section 110(k)(1) and (2); and (6) updates to 
the deadlines for the EPA action. In addition, in this section, the 
agency is proposing an interpretation regarding the effect under 
section 111 if an existing facility subject to CAA section 111(d) 
modifies or reconstructs. We believe these changes will significantly 
streamline the state plan review and approval process, be more 
respectful of state processes, and generally enhance the administration 
of the CAA section 111(d) program.
    CAA section 111(d)(1) provides that the EPA ``shall establish a 
procedure similar to that provided by CAA section [110] of this title 
under which each state shall submit to the Administrator a [111(d)] 
plan. . . .'' 42 U.S.C. 7411(d)(1). Thus, the CAA directs the EPA to 
look to the structure of the SIP program when designing the procedures 
the states and agency will use to develop CAA section 111(d) plans. 
Notably, the CAA does not require the CAA section 111(d) procedures to 
be identical to those the EPA uses under

[[Page 65035]]

CAA section 110 for SIPs.\120\ Therefore, the EPA interprets CAA 
section 111(d) to provide the EPA flexibility in designing procedures 
that reflect the structure of those used under CAA section 110 for 
implementation plans, without requiring the EPA to exactly track SIP 
procedures when acting on section 111(d) plans.
---------------------------------------------------------------------------

    \120\ See Webster's II New Riverside University Dictionary 
(Riverside 1988) (defining ``similar'' to mean ``resembling though 
not completely identical'').
---------------------------------------------------------------------------

    As a general matter these proposed changes would simply update the 
CAA section 111(d) framework regulations to include several new, more 
flexible procedural tools that Congress introduced into section 110 in 
the 1990 CAA Amendments. The basic procedures in the CAA section 111(d) 
framework regulations were promulgated in 1975 based on the structure 
of CAA section 110 as Congress designed it in the 1970 CAA. See 40 FR 
53340-49 (November 17, 1975). Over the years since 1970, the EPA and 
the states learned a great deal about the procedural limitations of the 
original SIP review process. The 1970 CAA only allowed the EPA two 
choices--to approve or disapprove SIP submittals. The agency struggled 
to deal responsively to situations where the EPA wanted to work with 
states to get state programs approved to the extent possible, while 
maintaining consistency with CAA requirements. Congress responded in 
1990 and enhanced the procedural mechanisms the EPA has to act on SIPs. 
The EPA is proposing correspondingly to update the CAA section 111(d) 
regulations in a similar fashion. Currently, the EPA's framework 
regulations for submittal and adoption of CAA section 111(d) state 
plans do not explicitly provide for the EPA to use some of the same 
procedures for approving or disapproving state plans Congress 
introduced into the SIP program in the 1990 CAA Amendments. The EPA is 
proposing to amend the procedures for approval or disapproval of CAA 
section 111(d) state plans to reflect the enhancements Congress 
included in CAA section 110 for agency actions on SIPs. These proposed 
amendments are discussed in more detail below.

A. Partial Approvals/Disapprovals

    First, the EPA proposes to add authority similar to that under CAA 
section 110(k)(3) to partially approve or disapprove a plan.\121\ This 
is a particularly useful function when much of a state plan is 
approvable and the EPA and the state cannot reach resolution on only a 
small, severable portion of the state plan. In this case, the EPA 
prefers not to be in a position where it must disapprove the full plan, 
but rather to allow the state to move forward with those portions of 
the plan that are approvable. This approach would also address those 
situations where the state wishes to take over a discrete part of a 
federal plan. For instance, in this proposal, states will be able to 
seek approval of a partial state plan that will give them the ability 
to handle the allocation of allowances under a mass-based federal plan.
---------------------------------------------------------------------------

    \121\ We recognize that the regulations appear to already 
contemplate partial approval/disapprovals to some extent. See 40 CFR 
60.27(a) (``The Administrator may . . . extend the period for 
submission of any plan . . . or portion thereof.'') (emphasis 
added). We note that this language only allows for extensions of 
time with respect to portions of state plan submissions and may not 
sufficiently authorize a permanent partial approval. The proposed 
enhancement will resolve any ambiguity that partial approvals/
disapprovals are an acceptable mechanism under CAA section 111(d).
---------------------------------------------------------------------------

    In cases where elements of a plan are functionally severable from 
each other, and one element is approvable while another is not, this 
provision will authorize the EPA to approve one part of a plan and 
disapprove the other. It will also authorize the EPA to accept and 
review a state plan that is only partial in nature, if identified by 
the state as such, so long as the other applicable submission 
requirements are met (such as demonstration of legal authority and 
completion of the public process). When the state submits what it 
intends to be a full state plan (rather than just a partial plan), the 
EPA proposes that the approvable portion of a plan must be functionally 
severable from the rest of the plan. This will be the case when the 
following conditions are met. First, the approvable portion of the plan 
must not depend on the rest of the plan. In other words, the 
disapproval of the remaining portion of the plan must not affect the 
portion that is approved. Second, approval of the approvable portion 
must not alter the function of the submittal in a way that is contrary 
to the state's intent.
    The partial disapproval would be a disapproval for the purposes of 
CAA section 111(d)(2)(A) and would trigger the EPA's authority to issue 
a federal plan for the state, at least for that part of the plan that 
was disapproved. Incorporating this mechanism under the framework 
regulations for CAA section 111(d) will enable the EPA to approve a 
state to implement as much of its program as is consistent with a CAA 
section 111(d) guideline and may reduce the scope of any federal plan 
that would be necessary.

B. Conditional Approvals

    The second mechanism is the authority under CAA section 110(k)(4) 
to conditionally approve a plan. Where a state has submitted a plan 
that substantially meets the requirements of a CAA section 111(d) 
emission guideline, but requires some specific amendments to make it 
fully approvable, this provision authorizes the EPA to conditionally 
approve the plan. The Governor or his/her designee must submit to the 
EPA a commitment that specifies the amendments to be adopted and 
submitted to the EPA by no later than 1 year from the effective date of 
the conditional approval. If the state fails to meet its commitment, 
the conditional approval is treated as a disapproval. Incorporating 
this mechanism under the framework regulations for CAA section 111(d) 
will enable the EPA to approve a state to begin to administer a 
substantially complete program that requires only specific changes to 
be fully approvable. This provision is designed to authorize a state 
with a substantially complete and approvable program to begin 
implementing it, while promptly amending the program to ensure it fully 
complies with CAA section 111(d).

C. Calls for Plan Revisions

    CAA section 110(k)(5) authorizes the EPA to find that a SIP does 
not comply with the requirements of the CAA. To date, the EPA has not 
considered using a similar procedure pursuant to the authority under 
CAA section 111(d). We now propose to do so. The ability to call for 
plan revisions is fundamental to a program that will be implemented 
over many years or multiple decades. Under the Clean Power Plan EGs, 
states have more than a decade to fully implement emissions standards 
or state measures in order to ensure affected EGUs achieve the emission 
goals of the EGs. Throughout this period, the EPA and the states will 
be monitoring their programs to ensure they are achieving the intended 
results. It is possible that design assumptions about the effect of 
control measures the states incorporate into their plans could prove 
inaccurate in retrospect and could result over time in the plan not 
meeting the emission reductions required by the EGs. In that case, 
having a procedural mechanism available under CAA section 111(d) 
similar to the so-called ``SIP call'' mechanism in CAA section 
110(k)(5) will allow the agency to initiate a process with the state to 
make necessary

[[Page 65036]]

revisions to ensure the plan functions properly.
    Accordingly, the EPA is proposing to amend the framework 
regulations to include a provision similar to CAA section 110(k)(5) 
under which the EPA may find that a state's CAA section 111(d) plan is 
substantially inadequate to comply with the requirements of the CAA and 
require the state to revise the plan as necessary to correct such 
inadequacies. Consistent with CAA section 110(k)(5), the EPA shall 
notify the state of any inadequacies and establish a reasonable 
deadline for the state to submit required plan revisions. That deadline 
will not exceed 18 months after the date of the action. The EPA will 
make its finding and notice to the state available to the public.\122\
---------------------------------------------------------------------------

    \122\ Consistent with the agency's practice under CAA section 
110(k)(5), the EPA anticipates that a call for plan revisions under 
CAA section 111(d) will be done via notice and comment rulemaking.
---------------------------------------------------------------------------

    The effect of such a finding is that either the state submits the 
program corrections by the date the EPA sets in the document, or 
pursuant to CAA section 111(d)(2)(A), the EPA has authority to issue a 
federal plan for a state that misses its deadline to correct its plan. 
In effect, the finding of plan inadequacy establishes a plan submittal 
deadline subject to the provisions of CAA section 111(d)(2)(A). A 
finding of failure to meet that new deadline triggers the EPA's 
authority to issue a federal plan for the state. The EPA may promulgate 
a federal plan at any time following the state's failure to timely 
submit an adequate plan that addresses the EPA's finding.
    While these authorities are important, the intention of having a 
mechanism to call for plan revisions is to have a way to initiate an 
orderly process to improve plans when they are not meeting program 
objectives. It is the EPA's hope that a call for plan revision leads to 
a constructive dialogue with a state or states, and ultimately, an 
improved and more effective CAA section 111(d) plan.
    The EPA is also proposing that the agency can call for a plan 
revision in circumstances where a state is not implementing its 
approved state plan and, therefore, the state plan is substantially 
inadequate to provide for the implementation of CAA section 111(d) 
standards of performance. As discussed above, the CAA directs the EPA 
to develop a procedure for state plans under CAA section 111(d) similar 
to CAA section 110 SIP procedures. Calling a plan that is substantially 
inadequate to provide for implementation of standards of performance 
(i.e., there is a failure to implement a state plan) is one area where 
the EPA proposes it is appropriate to adapt the procedural mechanisms 
available in the SIP program to provide a similar process that assures 
effective state plan implementation under CAA section 111(d). Under CAA 
section 110(k)(5), the EPA may call for a revision of a state plan 
``[w]henever the Administrator finds that the . . . plan . . . is 
substantially inadequate to . . . comply with any requirement of [the 
Act].'' If the state does not submit a plan revision in response to the 
call to cure the failure to provide for implementation, the EPA would 
have the authority to promulgate the federal plan being proposed.
    One critical requirement of CAA section 111(d)(1)(B) is that a 
state must submit a plan that ``provides for the implementation and 
enforcement of such standards of performance'' (emphasis added). If, 
after the EPA has approved a plan, a state fails to implement that 
plan, the plan has become substantially inadequate to comply with this 
requirement of the CAA. Under this proposal, the EPA's remedy would be 
to find the plan is substantially inadequate, which triggers the 
state's obligation to cure, and failing that, the EPA's authority to 
promulgate the federal plan.
    In the alternative, the EPA proposes that this authority to call a 
plan for failure to implement is anchored in the authority provided 
under CAA section 110(k)(5) to call a SIP when the agency finds that it 
is ``substantially inadequate to attain or maintain the relevant 
national ambient air quality standard.'' In the context of CAA section 
111, this authority translates into the EPA calling a state plan when 
the agency finds that it is substantially inadequate to achieve the 
emission reductions required under the EGs. If a state has failed to 
implement its plan, and that failure is pervasive enough to render the 
requirements of the plan ineffective, it is reasonable for the EPA to 
find that the state plan is substantially inadequate to achieve the 
emission reductions required under the EGs. The state's failure to 
implement has revised the effect of the plan so that it is no longer 
adequate to meet the CAA's requirements.

D. Error Corrections

    The fourth mechanism is the error correction authority under CAA 
section 110(k)(6). Where the EPA concludes that it has erroneously 
approved, disapproved, or promulgated a plan or plan revision (or part 
thereof), this section authorizes the agency to revise its action, in 
the same manner as the original action, without requiring any further 
submission from the state. Prior to the 1990 CAA Amendments, there was 
some question whether the EPA could unilaterally correct a previous 
action on a SIP submittal without the state having to submit a new SIP. 
This limitation imposed unnecessary burdens on states to fix even 
obvious errors, because CAA section 110(a)(2) requires the state to 
provide notice and a public hearing on each new SIP submittal. 
Incorporating this mechanism into the CAA section 111(d) framework 
regulations will allow the EPA to fix errors in its prior actions on 
state plans without imposing on the states the corresponding burden of 
providing notice and a public hearing as required under the CAA section 
111(d) framework regulations. See 40 CFR 60.23.

E. Completeness Criteria

    Completeness criteria provide the agency with a means to determine 
whether a submission by a state includes the minimum elements that must 
be met before the EPA is required to act on such submission. When 
submittals do not contain the necessary minimum elements, then the EPA 
may, without further action, find that a state has failed to submit a 
plan. This determination is ministerial in nature and requires no 
exercise of discretion or judgment on the agency's part, nor does it 
reflect a judgment on the sufficiency or adequacy of the submitted 
portions of a state plan. The task is accomplished by simply comparing 
the materials provided by the state as its submittal against the 
required criteria to determine whether the plan is complete or not. In 
the case of SIPs under CAA section 110(k)(1), the EPA promulgated 
completeness criteria in 1990 at Appendix V to 40 CFR part 51 (55 FR 
5830; February 16, 1990). The EPA proposes to adopt criteria similar to 
the criteria set out at section 2.0 of Appendix V for determining the 
completeness of submissions under CAA section 111(d). The completeness 
criteria can be grouped into: (1) Administrative materials; and (2) 
technical support. The EPA proposes that both groups would apply to all 
CAA section 111(d) rules going forward. The agency notes that the 
addition of completeness criteria in the framework regulations does not 
alter any of the submission requirements states already have under the 
EGs.
    For administrative materials, the EPA is proposing completeness 
criteria that mirror the existing administrative criteria for SIP 
submittals because the two programs have similar

[[Page 65037]]

administrative processes. The EPA proposes that a complete final state 
plan submittal under CAA section 111(d) must include: (1) A formal 
letter of submittal from the Governor or his/her designee requesting 
EPA approval of the plan or revision thereof; (2) evidence that the 
state has adopted the plan in the state code or body of regulations 
(That evidence must include the date of adoption or final issuance as 
well as the effective date of the plan, if different from the adoption/
issuance date.); (3) evidence that the state has the necessary legal 
authority under state law to adopt and implement the plan; (4) a copy 
of the actual regulation, or document submitted for approval and 
incorporation by reference into the plan. The submittal must be a copy 
of the official state regulation/document signed, stamped and dated by 
the appropriate state official indicating that it is fully enforceable 
by the state (The effective date of the regulation/document must, 
whenever possible, be indicated in the document itself. The state's 
electronic copy must be an exact duplicate of the hard copy. For 
revisions to the approved plan, the submittal must indicate the changes 
made (for example, by redline/strikethrough) to the approved plan.); 
(5) evidence that the state followed all of the procedural requirements 
of the state's laws and constitution in conducting and completing the 
adoption/issuance of the plan; (6) evidence that public notice was 
given of the proposed change with procedures consistent with the 
requirements of 40 CFR 60.23, including the date of publication of such 
notice; (7) certification that public hearing(s) were held in 
accordance with the information provided in the public notice and the 
state's laws and constitution, if applicable and consistent with the 
public hearing requirements in 40 CFR 60.23; and (8) compilation of 
public comments and the state's response thereto.
    These criteria, as proposed, are intended to be generic to all CAA 
section 111(d) plans going forward, with the proviso that specific EGs 
may provide otherwise. The technical support completeness criteria that 
the EPA proposes will also be generic to all CAA section 111(d) rules, 
with the same proviso. The EPA proposes that the technical support 
required for all plans must include each of the following: (1) 
Description of the plan approach and geographic scope; (2) 
identification of each designated facility, identification of emission 
standards for each designated facility, and monitoring, recordkeeping, 
and reporting requirements that will determine compliance by each 
designated facility; (3) identification of compliance schedules and/or 
increments of progress; (4) demonstration that the state plan submittal 
is projected to achieve emissions performance under the applicable EGs; 
(5) documentation of state recordkeeping and reporting requirements to 
determine the performance of the plan as a whole; and (6) demonstration 
that each emission standard is quantifiable, non-duplicative, 
permanent, verifiable, and enforceable.
    The EPA proposes a process similar, though not identical, to that 
set forth in 40 CFR 51.103 and Appendix V to 40 CFR part 51 to make 
completeness determinations. Similar to CAA section 110(k)(1)(C), under 
this proposal, where the EPA determines that a state submission 
required under CAA section 111(d) does not meet the minimum 
completeness criteria we are proposing to establish, the state will be 
considered to have not made the submission. The EPA further proposes 
that, similar to CAA section 110(k)(1)(B), within 60 days of the EPA's 
receipt of a state submission, but no later than 6 months after the 
date, if any, by which a state is required to submit the plan or 
revision, the Administrator shall determine whether the minimum 
criteria have been met. Any plan or plan revision that a state submits 
to the EPA, and that has not been determined by the EPA by the date 6 
months after receipt of the submission to have failed to meet the 
minimum criteria, shall on that date be deemed by operation of law to 
meet such minimum criteria. In cases where a state does not submit 
anything to the agency, however, the Administrator must make a finding 
of failure to submit no later than 6 months after the date, if any, by 
which a state is required to submit the plan or revision. (In other 
words, ``completeness by operation of law'' is only available where the 
state has actually submitted a plan to the agency.)
    As with the completeness determination process for SIP submissions, 
the EPA's determination that a submittal is complete is not a finding 
that the submittal meets the substantive requirements of CAA section 
111(d) or the guideline. That must be done via the process for approval 
or disapproval of a state plan, which would be done through notice and 
comment rulemaking. In the completeness process, the EPA will confirm 
that a state's submittal appears to have addressed the criteria for a 
complete submittal and, therefore, the submittal is sufficient to 
trigger the EPA's obligation to act on it. But in the completeness 
process the agency will not assess the content of those submissions to 
determine if they are approvable. Accordingly, even when the EPA 
affirmatively determines that a submittal is complete, it does not 
prevent the agency from later finding that the state plan does not meet 
the requirements of the EGs, including finding that the submittal 
failed to address a required element and must be disapproved.
    Similarly, when a submittal is determined to be complete by 
operation of law after 6 months without the EPA's affirmative 
determination of completeness, the only legal consequence is that the 
EPA now has an obligation to act on that submittal. Completeness by 
operation of law means that the submittal is deemed complete and 
requires the EPA's review, whether or not the state has actually 
addressed all the required elements. Accordingly, if the agency 
determines that a state has failed to address a required element in its 
submittal once the EPA begins review of the state plan that is complete 
by operation of law, the agency must go through the process of 
disapproving (or partially disapproving or conditionally approving, as 
discussed below) that plan, unless the state and the EPA work together 
to cure the deficiency. In other words, the EPA cannot simply find the 
plan incomplete and return it to the state at that point. But the 
finding of completeness by operation of law in no way prevents the EPA 
from subsequently concluding that the state's submission is missing a 
required element of the program and making that finding as part of a 
disapproval of the plan.
    As described in the final rulemaking action for the CAA section 
111(d) EGs, a state will submit all CAA section 111(d) plans 
electronically. If the EPA determines that any submission fails to meet 
the completeness criteria, the agency may return the plan to the state 
and request corrections, identifying the components that are absent or 
insufficient to allow the EPA to perform a review of the plan. The 
state will not have met its obligation to submit a final plan until it 
resubmits a revised state plan or supporting materials addressing the 
corrections the EPA identified in its incompleteness determination.
    The EPA is also proposing to include an exception to the criteria 
for complete administrative materials in cases where a state and the 
EPA are ``parallel processing'' the final plan. Parallel processing 
allows a state to submit the plan prior to final adoption by the state 
and provides an opportunity for the

[[Page 65038]]

state to consider the EPA's comments prior to submission of a final 
plan for final review and action. The EPA would propose to take action 
on a state plan based on a proposed state regulation. The EPA would 
only finalize the action if the state adopts a final plan that is 
legally effective under state law. The EPA would only approve the plan 
if the state addressed any corrections that the EPA identified in its 
proposed action on the state plan without any other material change to 
the plan. Note that a plan submitted for parallel processing must still 
meet all the criteria for technical completeness so that the EPA and 
the public have a sufficient basis on which to evaluate and comment on 
the EPA's proposed action.

F. Update to Deadlines for EPA Actions

    The EPA proposes to update the deadlines for acting on state 
submittals and promulgating a federal plan under 40 CFR 60.27(b), (c), 
and (d) to more closely track the current versions of CAA sections 
110(c) and 110(k) adopted in 1990. The framework regulations for CAA 
section 111(d) state plans currently are parallel to the prior version 
of CAA section 110. They require the EPA to act on a state plan or plan 
revision submittal within 4 months after the date required for 
submission of a plan or plan revision. See 40 CFR 60.27(b). The 
regulations then require the EPA to issue a proposed federal plan in 
certain circumstances after consideration of any state hearing record, 
see 40 CFR 60.27(c), and require the EPA to promulgate the proposed 
federal plan within 6 months after the date required for plan 
submissions, see 40 CFR 60.27(d).
    The final CO2 EGs for affected EGUs have already 
adjusted the deadline in 40 CFR 60.27(b) to require the EPA to act on a 
state plan under those EGs within 12 months (rather than 4 months) 
after the date required for submission of a plan. See 40 CFR 60.5715. 
However, the Clean Power Plan EGs did not modify the 6-month deadline 
for a federal plan in 40 CFR 60.27(d).
    The EPA is proposing to amend 40 CFR 60.27(b) to allow the EPA 12 
months to approve or disapprove submittals of all plans or plan 
revisions under CAA section 111(d), not just those related to the Clean 
Power Plan under 40 CFR 60.5715. This change would provide the EPA with 
sufficient time for the steps required to approve or disapprove the 
submittal, which include proposing the EPA's approval or disapproval of 
the plan or plan revision, a public comment period on the EPA's 
proposal, time for the EPA to review and respond to public comments, 
and the issuance of a final rule approving or disapproving the plan or 
plan revision.
    The EPA is also proposing to amend 40 CFR 60.27(b) to specify that 
the deadline for the EPA to act on a plan or plan revision is 12 months 
after receipt of a complete plan or plan revision, rather than 12 
months after the deadline for submittal of a plan or plan revision. 
This amendment will allow the EPA to have the full 12 months to act on 
submittals of complete plans or plan revisions.
    The EPA also proposes slight modifications to the provision related 
to issuing a proposed federal plan in 40 CFR 60.27(c); changing the 6-
month deadline for issuing a final federal plan in 40 CFR 60.27(d) to 1 
year; \123\ and, similar to the change in timing for 40 CFR 60.27(b) 
above, setting the deadline for promulgation of a federal plan to run 
from the date of the EPA's action on a state submittal, rather than 
from the original deadline for a state submittal.
---------------------------------------------------------------------------

    \123\ As under CAA section 110, the EPA believes that, should it 
fail for whatever reason to meet a deadline by which it was to take 
action, such as issue a federal plan, under CAA section 111(d), that 
failure does not thereby obviate or in any way remove the EPA's 
authority or obligation to take that action. See Oklahoma v. U.S. 
EPA, 723 F.3d 1201, 1224 (10th Cir. 2013) (``Although the statute 
undoubtedly requires that the EPA promulgate a FIP within two years, 
it does not stand to reason that it loses its ability to do so after 
this two-year period expires. Rather, the appropriate remedy when 
the EPA violates the statute is an order compelling agency 
action.'').
---------------------------------------------------------------------------

    The EPA believes it is appropriate to modify these timing 
requirements for several reasons. First, the EPA notes that under CAA 
section 111(d)(2), Congress gave the EPA the ``same'' authority to 
prescribe a federal plan under CAA section 111(d) as it would have 
under CAA section 110(c) in the case of a state failure to submit a 
SIP. The term ``same'' stands in contrast to the term ``similar'' in 
CAA section 111(d)(1) (discussed above). As with the use of the term 
``similar,'' the EPA believes it is authorized by this language to 
follow the timing provisions of CAA section 110(c) as currently 
enacted. Second, as a general matter, the timing requirements of 
current 40 CFR 60.27(c) and (d), which effectively require the EPA to 
propose and finalize a federal plan within 6 months of the deadline for 
state submittals, may be outdated and unrealistic with respect to the 
timelines for review of state plans and the time periods for action, 
particularly as informed by the agency's experience with CAA section 
110 SIPs (which led to the extension of the timelines and other changes 
to CAA section 110 in the 1990 Amendments discussed above). Third, in 
the Clean Power Plan EGs, the EPA has finalized a timing requirement 
that gives the agency a year to approve or disapprove a state plan or 
revision. The existing requirement in 40 CFR 60.27(d) that the EPA must 
promulgate a federal plan within 6 months of the initial deadline for 
state plans is therefore inconsistent with this provision. Fourth, 
existing 40 CFR 60.27(c) tracks the prior version of CAA section 110(c) 
with respect to the issuance of a proposed federal plan. This 
relatively prescriptive language is no longer present in CAA section 
110(c). The procedural requirements for rulemakings under both CAA 
section 110 and 111(d) are set out in section 307(d) of the CAA, and 
the EPA believes those provisions are appropriate and adequate to guide 
its rulemaking process for CAA section 111(d) federal plans.
    The EPA invites comment on all of these proposed changes to the 
framework regulations. The EPA notes that the addition of these 
mechanisms to the framework regulations will make them available for 
all CAA section 111(d) regulations, not just those under the Clean 
Power Plan at 40 CFR part 60, subpart UUUU.

G. Proposed Interpretation Regarding Existing Sources That Modify or 
Reconstruct

    In the proposed rulemaking for the Clean Power Plan, the EPA 
proposed the interpretation that if an existing source is subject to a 
CAA section 111(d) state plan, and then undertakes a modification or 
reconstruction, the source remains subject to the state plan, while 
also becoming subject to the modification or reconstruction 
requirements. See 79 FR 34830, 34903-4 (June 18, 2014). The EPA did not 
finalize a position on this issue in the final EGs rule, but indicated 
that it would re-propose and request comment on this issue through this 
federal plan rulemaking. The EPA also stated deferral of action on this 
issue does not impact states' and affected EGUs' pending obligations 
under the final Emission Guidelines relating to plan submission 
deadlines, as this issue concerns potential obligations or impacts 
after an existing source has already become subject to the requirements 
of a state plan. The EPA intends to finalize its position on this issue 
through this rulemaking, which will be well in advance of the plan 
performance period beginning in 2022, at which point state plan 
obligations on existing sources are effectuated.
    We noted in the Clean Power Plan proposal that CAA section 111(d) 
is arguably silent as to this issue. Thus, we

[[Page 65039]]

took this to grant the agency the authority to provide a reasonable 
interpretation to fill in the gaps where the statute is silent. In the 
proposal for the Clean Power Plan, we proposed to disallow existing 
sources to leave the CAA section 111(d) program through modification or 
reconstruction. We did this for two reasons. First, if a source did so, 
that could prove disruptive to the state plan. Second, allowing sources 
to do so could provide them an incentive that would be contrary to the 
purposes of CAA section 111(d). We then asked for comment on ``whether 
this interpretation is supported by the statutory text and whether this 
interpretation is sensible policy and will further the goals of the 
statute.''
    We received many comments disagreeing with this approach. After 
reviewing these comments, the agency believes an alternative 
interpretation is more appropriate in the particular context here. In 
order to give the public an opportunity to comment on this, we are 
proposing this interpretation here. That is, when CAA section 111(d) 
EGs are initially promulgated for existing stationary sources in 
response to corresponding CAA section 111(b) standards of performance 
for the same pollutant, the statute prevents new, modified, or 
reconstructed sources (including under those particular CAA section 
111(b) standards of performance and as those terms are applied in the 
relevant new source performance standards (NSPS)) from simultaneously 
being subject to state plans under those particular CAA section 111(d) 
EGs. This interpretation gives meaning to the definition of ``existing 
source'' in CAA section 111(a)(6) and is consistent with the definition 
of ``new source'' in CAA section 111(a)(2). Further, it is consistent 
with the historical treatment of modified and reconstructed sources in 
the CAA section 111 program.
    The EPA notes the concerns it noted in the proposal supporting why 
the originally proposed interpretation was reasonable are being 
addressed in other ways in the final EGs, and in the proposed federal 
plan. In other words, there will be other ways to minimize disruption 
to state plans if such a modification or reconstruction were to take 
place. We invite comment on the agency's proposed interpretation that 
when an existing source modifies or reconstructs in such a way that it 
meets the definition of a new source, for purposes of a particular NSPS 
and emission guideline, it becomes a new source under the statute and 
is no longer subject to the CAA section 111(d) program

H. Separate Finalization of These Changes

    The agency intends to finalize these procedural changes and 
interpretation sooner than it finalizes the rest of this proposed 
action. The EPA believes these changes generally enhance and improve 
the framework regulations in a way that will be of benefit to the 
states, the EPA, and other stakeholders, and will improve the overall 
efficacy of the program. We believe it is important to finalize these 
changes to the framework regulations relatively quickly in order to 
provide states and other stakeholders predictability in how the EPA 
intends to process state plans and submissions under CAA section 
111(d). If the EPA does finalize these changes sooner than the model 
trading rules or the federal plan, it will do so after the close of the 
comment period, and after consideration and response to any comments on 
these changes.

VIII. Impacts of This Action

A. Endangered Species Act

    Consistent with the requirements of section 7(a)(2) of the 
Endangered Species Act (ESA), the EPA has considered the effects of 
this proposed rule and has reviewed applicable ESA regulations, case 
law, and guidance to determine what, if any, impact there may be to 
listed endangered or threatened species or designated critical habitat. 
Section 7(a)(2) of the ESA requires federal agencies, in consultation 
with the U.S. Fish and Wildlife Service (FWS) and/or the National 
Marine Fisheries Service, to ensure that actions they authorize, fund, 
or carry out are not likely to jeopardize the continued existence of 
federally listed endangered or threatened species or result in the 
destruction or adverse modification of designated critical habitat of 
such species. See 16 U.S.C. 1536(a)(2). Under relevant implementing 
regulations, ESA section 7(a)(2) applies only to actions where there is 
discretionary federal involvement or control. See 50 CFR 402.03. 
Further, under the regulations consultation is required only for 
actions that ``may affect'' listed species or designated critical 
habitat. See 50 CFR 402.14. Consultation is not required where the 
action has no effect on such species or habitat. Under this standard, 
it is the federal agency taking the action that evaluates the action 
and determines whether consultation is required. See 51 FR 19926, 19949 
(June 3, 1986). Effects of an action include both the direct and 
indirect effects that will be added to the environmental baseline. See 
50 CFR 402.02. Direct effects are the direct or immediate effects of an 
action on a listed species or its habitat.\124\ Indirect effects are 
those that are caused by the action, later in time, and are reasonably 
certain to occur. Id. To trigger a consultation requirement, there must 
thus be a causal connection between the federal action, the effect in 
question, and if the effect is indirect, it must be reasonably certain 
to occur.
---------------------------------------------------------------------------

    \124\ See Endangered Species Consultation Handbook, U.S. Fish & 
Wildlife Service and National Marine Fisheries Service at 4-25 
(March 1998) (providing examples of direct effects: e.g., driving an 
off road vehicle through the nesting habitat of a listed species of 
bird and destroying a ground nest; building a housing unit and 
destroying the habitat of a listed species).
---------------------------------------------------------------------------

    The EPA has considered the effects of this proposed rule and has 
reviewed applicable ESA regulations, case law, and guidance to 
determine what, if any, impact there may be to listed species or 
designated critical habitat for purposes of ESA section 7(a)(2) 
consultation. The EPA notes that the projected environmental effects of 
this proposal are, like the EGs that it implements, positive: 
Reductions in overall GHG emissions, and reductions in PM and ozone-
precursor emissions (sulfur oxides and NOX), for EGUs that 
will be covered by the federal plan. However, the EPA's assessment that 
the rule will have an overall net positive environmental effect by 
virtue of reducing emissions of certain air pollutants does not address 
whether the rule may affect any listed species or designated critical 
habitat for ESA section 7(a)(2) purposes and does not constitute any 
finding of effects for that purpose. The fact that the rule will have 
overall positive effects on the national and global environment does 
not mean that the rule may affect any listed species in its habitat or 
the designated critical habitat of such species within the meaning of 
ESA section 7(a)(2) or the implementing regulations or require ESA 
consultation. The EPA has considered various types of potential effects 
in considering whether ESA consultation is required for this rule.
    With respect to the projected GHG emission reductions, the EPA does 
not believe that such reductions trigger ESA consultation requirements 
under ESA section 7(a)(2). In reaching this conclusion, the EPA is 
mindful of significant legal and technical analysis undertaken by FWS 
and the U.S. Department of the Interior (DOI) in the context of listing 
the polar bear as a threatened species under the ESA. In that context, 
in 2008, FWS and DOI expressed the view that the best scientific data 
available were insufficient to draw a causal connection

[[Page 65040]]

between GHG emissions and effects on the species in its habitat.\125\ 
The DOI Solicitor concluded that where the effect at issue is climate 
change, proposed actions involving GHG emissions cannot pass the ``may 
affect'' test of the ESA section 7 regulations and, thus, are not 
subject to ESA consultation.
---------------------------------------------------------------------------

    \125\ See, e.g., 73 FR 28212, 28300 (May 15, 2008); Memorandum 
from David Longly Bernhardt, Solicitor, U.S. Department of the 
Interior re: ``Guidance on the Applicability of the Endangered 
Species Act's Consultation Requirements to Proposed Actions 
Involving the Emission of Greenhouse Gases'' (October 3, 2008).
---------------------------------------------------------------------------

    The EPA has also previously considered issues relating to GHG 
emissions in connection with the requirements of ESA section 7(a)(2). 
In the final EGs, the agency noted that, although the GHG emission 
reductions projected for the EGs are large (estimated reductions of 
about 415 million short tons of CO2 in 2030 relative to the 
base case), the EPA evaluated larger reductions in assessing this same 
issue in the context of the light duty vehicle GHG emission standards 
for model years 2012-2016 and 2017-2025. There the agency projected 
emission reductions over the lifetimes of the model years in 
question,\126\ which are roughly five to six times those projected 
above and, based on air quality modeling of potential environmental 
effects, concluded that ``EPA knows of no modeling tool which can link 
these small, time-attenuated changes in global metrics to particular 
effects on listed species in particular areas. Extrapolating from 
global metric to local effect with such small numbers, and accounting 
for further links in a causative chain, remain beyond current modeling 
capabilities.'' EPA, Light Duty Vehicle Greenhouse Gas Standards and 
Corporate Average Fuel Economy Standards, Response to Comment Document 
for Joint Rulemaking at 4-102 (Docket EPA-OAR-HQ-2009-4782). The EPA 
reached this conclusion after evaluating issues relating to potential 
improvements from the fuel efficiency rule relevant to both temperature 
and oceanographic pH outputs. The EPA's ultimate finding was that ``any 
potential for a specific impact [of the specific federal action] on 
listed species in their habitats associated with these very small 
changes in average global temperature and ocean pH is too remote to 
trigger the threshold for ESA section 7(a)(2).'' Id. See also, e.g., 
Ground Zero Center for Non-Violent Action v. U.S. Dept. of Navy, 383 F. 
3d 1082, 1091-92 (9th Cir. 2004). The EPA similarly proposes to 
determine that the likelihood of jeopardy to a species from this 
proposed action is extremely remote, and ESA does not require 
consultation. The EPA's proposed conclusion is entirely consistent with 
DOI's analysis regarding ESA requirements in the context of federal 
actions involving GHG emissions.
---------------------------------------------------------------------------

    \126\ See 75 FR 25438 Table I.C 2-4 (May 7, 2010); 77 FR at 
62894 Table III-68 (October 15, 2012).
---------------------------------------------------------------------------

    With regard to non-GHG air emissions, the EPA is also projecting 
substantial reductions of SO2 and NOX as a 
collateral consequence of this proposal (which will be, as stated 
above, only a subset of the total reductions from the EGs). However, 
CAA section 111(d) cannot directly control emissions of criteria 
pollutants. And furthermore, a federal plan under CAA section 111(d)(2) 
does no more than prescribe emissions standards of the same stringency 
as the corresponding EGs. See 40 CFR 60.27(e)(1). Consequently, CAA 
section 111(d) provides no discretion to set a standard in a federal 
plan based on potential impacts to endangered species of reduced 
criteria pollutant emissions. ESA section 7(a)(2) consultation is not 
required with respect to the projected reductions of criteria pollutant 
emissions. See 50 CFR 402.03; see also WildEarth Guardians v. U.S. 
Envt'l Protection Agency, 759 F.3d 1196, 1207-10 (10th Cir. 2014) (the 
EPA has no duty to consult under section 7 of the ESA regarding HAP 
controls that it did not require--and likely lacked authority to 
require--in a FIP for regional haze controls under section 169A of the 
CAA.).
    Finally, the EPA has also considered other potential effects of the 
rule (beyond reductions in air pollutants) and whether any such effects 
are ``caused by'' the rule and ``reasonably certain to occur'' within 
the meaning of the ESA regulatory definition of the effects of an 
action. See 50 CFR 402.02. The EPA recognizes, for instance, that 
questions may exist whether decisions such as increased utilization of 
solar or wind power could have effects on listed species. The EPA 
received comments on the EGs asserting that because potential increased 
reliance on wind or solar power may be an element of Building Block 3, 
and because wind and solar facilities may in some cases have effects on 
listed species, the EPA must consult under the ESA on this aspect of 
the rule.
    The EPA has carefully considered the comments and the 
correspondence from Congress as well as the case law and other 
materials cited in those documents. The EPA does not believe that the 
effects of potential future changes in the energy sector--including 
increased reliance on wind or solar power as a result of future 
potential actions by states or other implementing entities--or any 
potential alterations in the operations of any particular facility 
would, at the time of promulgation of a federal plan, be sufficiently 
certain to occur so as to require ESA consultation on the rule. The EPA 
appreciates that the ESA regulations call for consultation where 
actions authorized, funded, or carried out by federal agencies may have 
indirect effects on listed species or designated critical habitat. 
However, as noted above, indirect effects must be caused by the action 
at issue and must be reasonably certain to occur.
    Under a federal plan, it is the EPA that would implement a CAA 
section 111(d) plan. The EPA believes that even with this proposed 
federal plan, any effects on listed species or designated habitat are 
too uncertain to require consultation under ESA section 7. This is so 
for at least two reasons: (1) The EPA cannot know with any certainty at 
this stage which states will actually become subject to a finally 
promulgated federal plan. Which affected EGUs, in which states, will be 
covered by this plan can only be known after states have failed to 
submit a plan, or have had their plans disapproved by the EPA; and (2) 
the federal plan as proposed will be implemented through some form of 
emissions trading. Emissions trading inherently provides maximum 
flexibility to individual affected EGUs to choose their method of 
compliance, including continuing to emit the relevant pollutant at 
historical rates so long as the affected EGU holds sufficient credits 
or allowances. At this point, the EPA has no meaningful information to 
express in any more than the broadest terms how any particular affected 
EGU may choose to comply with the federal plan, should it be 
promulgated for them based on their location in an area not covered by 
an approved state plan. The Services have explained that ESA section 
7(a)(2) was not intended to preclude federal actions based on potential 
future speculative effects.\127\

[[Page 65041]]

These are precisely the types of speculative future activities and 
effects currently at issue here. The EPA requests comment on its 
proposed conclusion that ESA section 7 consultation is not required for 
this action. The EPA will continue to evaluate the scope and potential 
effects of federal planning activities for this source category to the 
extent federal plans are needed and implemented in specific areas and 
over specific sources.
---------------------------------------------------------------------------

    \127\ See 51 FR 19933 (describing effects that are ``reasonably 
certain to occur'' in the context of consideration of cumulative 
effects and distinguishing broader consideration that may be 
appropriate in applying a procedural statute such as the National 
Environmental Policy Act, as opposed to a substantive provision such 
as ESA section 7(a)(2) that may prohibit certain federal actions); 
Endangered Species Consultation Handbook, U.S. Fish & Wildlife 
Service and National Marine Fisheries Service at 4-30 (March 1998) 
(in the same context, describing indicators that an activity is 
reasonably certain to occur as including governmental approvals of 
the action or indications that such approval is imminent, project 
sponsors' assurance that the action will proceed, obligation of 
venture capital, or initiation of contracts; and noting that the 
more governmental administrative discretion remains to be exercised, 
the less there is reasonable certainty the action will proceed).
---------------------------------------------------------------------------

B. What are the air impacts?

    The EPA anticipates significant emission reductions under this 
proposed action for the utility power sector. Specifically, the EPA is 
proposing approaches in the form of mass- and rate-based trading 
options that provide flexibility in implementing emission standards for 
a state's affected EGUs. Both proposed approaches to the federal plan 
would require affected EGUs to meet emission standards set using the 
CO2 emission performance rates in the Clean Power Plan EGs.
    However, at the time of this proposal, the EPA has no information 
on whether any or how many states will require a federal plan or will 
adopt a model rule. Because of this lack of information, in the 
Regulatory Impact Analysis (RIA) for this proposal, the EPA chose to 
examine a scenario where all states of the contiguous United States 
will be regulated under a federal plan or will adopt the model rule. 
Additionally, we examine two alternative federal plan approach 
scenarios. The first federal plan approach assumes all states in the 
contiguous United States are regulated under a rate-based federal plan. 
The second federal plan approach assumes all contiguous states are 
regulated under a mass-based federal plan.\128\
---------------------------------------------------------------------------

    \128\ It is important to note that the differences between the 
analytical results for the rate-based and mass-based federal plan 
approaches presented may not be indicative of likely differences 
between the approaches. If one approach performs differently than 
the other on a given metric during a given time period, this does 
not imply this will apply in all instances.
---------------------------------------------------------------------------

    Under the rate-based approach, when compared to 2005, 
CO2 emissions are projected to be reduced by approximately 
22 percent in 2020, 28 percent in 2025, and 32 percent in 2030. Under 
the mass-based approach, when compared to 2005, CO2 
emissions are projected to be reduced by approximately 23 percent in 
2020, 29 percent in 2025, and 32 percent in 2030. The proposal is 
projected to result in substantial co-benefits through reductions of 
SO2, NOX, and PM2.5 that will have 
direct public health benefits by lowering ambient levels of these 
pollutants and ozone. Table 12 and Table 13 of this preamble show 
expected CO2 and other air pollutant emissions in the base 
case and reductions under the proposal for 2020, 2025, and 2030 for 
both rate-based and mass-based approaches.

    The reductions in Tables 12 and 13 of this preamble do not account 
for reductions in HAP that may occur as a result of this rule. For 
instance, the fine particulate reductions presented above do not 
reflect all of the reductions in many heavy metal particulates.

C. What are the energy impacts?

    The proposed action may have important energy market implications. 
Table 14 of this preamble presents a variety of important energy market 
impacts for 2020, 2025, and 2030 under both the rate-based and mass-
based federal plan approaches described in section VIII.B of this 
preamble and presented in the RIA for this proposal.

    These figures reflect the EPA's modeling that presumes policies 
that lead to generation shifts and growing use of DS-EE and renewable 
electricity generation out to 2029. If different implementation choices 
are made than those modeled, impacts could be different.

D. What are the compliance costs?

    The compliance costs of this proposed action are represented in 
this analysis as the change in electric power generation costs between 
the base case and modeled federal plan approaches described in section 
VIII.B of this preamble and presented in the RIA for this proposal. The 
incremental cost is the projected additional cost of complying with the 
proposed action in the year analyzed and includes the amortized cost of 
capital investment, needed new capacity, shifts between or among 
various fuels, deployment of DS-EE programs, and other actions 
associated with compliance. These important dynamics are discussed in 
more detail in the RIA in the rulemaking docket.
    The EPA estimates the annual incremental compliance cost for the 
rate-based federal plan approach to be $2.5 billion in 2020, $1.0 
billion in 2025 and $8.4 billion in 2030. The EPA estimates the annual 
incremental compliance cost for the mass-based federal plan approach to 
be $1.4 billion in 2020, $3.0 billion in 2025, and $5.1 billion in 
2030. More detailed cost estimates are available in the RIA in the 
rulemaking docket.

E. What are the economic and employment impacts?

    Based on the analysis presented in the RIA, the proposed action is 
projected to result in certain changes to power system operation as a 
compliance approach with the standards. See Table 14 of this preamble 
for a variety of important energy market impacts for 2020, 2025, and 
2030 under both the rate-based and mass-based federal plan approaches 
described in Section VIII.B of this preamble and presented in the RIA 
for this proposal.
    Changes in price or demand for electricity, natural gas, and coal 
can impact markets for goods and services produced by sectors that use 
these energy inputs in the production process or supply those sectors. 
Changes in the cost of production may result in changes in prices, 
quantities produced, and profitability of affected firms. The EPA 
recognizes that the EGs provide significant flexibilities and states 
implementing the EGs may choose to mitigate impacts to some markets 
outside the utility power sector. Similarly, demand for new generation 
or DS-EE as a result of states implementing the guidelines can result 
in shifts in production and profitability for firms that supply those 
goods and services.
    Executive Order 13563 directs federal agencies to consider the 
effect of regulations on job creation and employment. According to the 
Executive Order, ``our regulatory system must protect public health, 
welfare, safety, and our environment while promoting economic growth,

[[Page 65043]]

innovation, competitiveness, and job creation. It must be based on the 
best available science.'' (Executive Order 13563, 2011). Although 
standard benefit-cost analyses have not typically included a separate 
analysis of regulation-induced employment impacts, we typically conduct 
employment analyses. While the economy continues to move toward full 
employment, employment impacts are of particular concern and questions 
may arise about their existence and magnitude.
    The EPA's employment analysis includes projected employment impacts 
associated with modeled federal plan approaches for the electric power 
industry, coal and natural gas production, and DS-EE activities. These 
projections are derived, in part, from a detailed model of the utility 
power sector used for this regulatory analysis, and U.S. government 
data on employment and labor productivity. In the electricity, coal, 
and natural gas sectors, the EPA estimates that the proposed action 
could result in a net decrease of approximately 25,000 job-years in 
2025 under the rate-based federal plan approach and approximately 
26,000 job-years in 2025 under the mass-based approach. For 2030, the 
estimates of the net decrease in job-years are 31,000 under the rate-
based approach and 34,000 under the mass-based approach. The agency is 
also offering an illustrative calculation of potential employment 
effects due to DS-EE programs. Employment impacts from DS-EE programs 
in 2030 could range from approximately 52,000 to 83,000 jobs under the 
proposal.
    By its nature, DS-EE reduces overall demand for electric power. The 
EPA recognizes as more efficiency is built into the U.S. power system 
over time, lower fuel requirements may lead to fewer jobs in the coal 
and natural gas extraction sectors, as well as in fossil fuel-fired EGU 
construction and operation than would otherwise have been expected. The 
EPA also recognizes the fact that, in many cases, employment gains and 
losses that might be attributable to this rule would be expected to 
affect different sets of people. Moreover, workers who lose jobs in 
these sectors may find employment elsewhere just as workers employed in 
new jobs in these sectors may have been previously employed elsewhere. 
Therefore, the employment estimates reported in these sectors may 
include workers previously employed elsewhere. This analysis also does 
not capture potential economy-wide impacts due to changes in prices (of 
fuel, electricity, or labor, for example) or other factors such as 
improved labor productivity and reduced health care expenditures 
resulting from cleaner air. For these reasons, the numbers reported 
here should not be interpreted as a net national employment impact.

F. What are the benefits of the proposed action?

    Implementing the proposed action will generate benefits by reducing 
emissions of CO2 and criteria pollutant precursors, 
including SO2, NOX, and directly emitted 
particles. SO2 and NOX are precursors to 
PM2.5 (particles smaller than 2.5 microns), and 
NOX is a precursor to ozone. The estimated benefits 
associated with these emission reductions are beyond those achieved by 
previous EPA rulemakings including the Mercury and Air Toxics Standards 
rule. The health and welfare benefits from reducing air pollution are 
considered co-benefits for this proposal. For this rulemaking, we were 
only able to quantify the climate benefits from reduced emissions of 
CO2 and the health co-benefits associated with reduced 
exposure to PM2.5 and ozone. There are many additional 
benefits which we are not able to quantify, leading to an underestimate 
of monetized benefits. In summary, we estimate the total combined 
climate benefits and health co-benefits for the rate-based federal plan 
approach to be $3.5 to $4.6 billion in 2020, $18 to $28 billion in 
2025, and $34 to $54 billion in 2030 (3 percent discount rate, 2011$). 
Total combined climate benefits and health co-benefits for the mass-
based federal plan approach are estimated to be $5.3 to $8.1 billion in 
2020, $19 to $29 billion in 2025, and $32 to $48 billion in 2030 (3 
percent discount rate, 2011$). A summary of the emission reductions and 
monetized benefits estimated for this rule at all discount rates is 
provided in Tables 15 through 17 of this preamble.

\a\ All estimates are rounded to two significant figures, so estimates may not sum. It is important to note that
  the monetized co-benefits do not include reduced health effects from direct exposure to SO2, direct exposure
  to NO2, exposure to mercury, ecosystem effects, or visibility impairment. Air pollution health co-benefits are
  estimated using regional benefit-per-ton estimates for the contiguous United States.
\b\ The monetized PM2.5 co-benefits reflect the human health benefits associated with reducing exposure to PM2.5
  through reductions of PM2.5 precursors, such as SO2 and NOX. The co-benefits do not include the benefits of
  reductions in directly emitted PM2.5. These additional benefits would increase overall benefits by a few
  percent based on the analyses conducted for the proposed Clean Power Plan EGs. PM co-benefits are shown as a
  range reflecting the use of two concentration-response functions, with the lower end of the range based on a
  function from Krewski et al. (2009) and the upper end based on a function from Lepeule et al. (2012). These
  models assume that all fine particles, regardless of their chemical composition, are equally potent in causing
  premature mortality because the scientific evidence is not yet sufficient to allow differentiation of effect
  estimates by particle type.
\c\ The monetized ozone co-benefits reflect the human health benefits associated with reducing exposure to ozone
  through reductions of NOX during the ozone season. Ozone co-benefits are shown as a range reflecting the use
  of several different concentration-response functions, with the lower end of the range based on a function
  from Bell, et al. (2004) and the upper end based on a function from Levy, et al. (2005). Ozone co-benefits
  occur in the analysis year, so they are the same for all discount rates.
\d\ We estimate climate benefits associated with four different values of a one ton CO2 reduction (model average
  at 2.5 percent discount rate, 3 percent, and 5 percent; 95th percentile at 3 percent). Referred to as the
  social cost of carbon, each value increases over time. For the purposes of this table, we show the benefits
  associated with the model average at 3 percent discount rate, however we emphasize the importance and value of
  considering the full range of social cost of carbon values. We provide combined climate and health estimates
  based on additional discount rates in the RIA.

\d\ We estimate climate benefits associated with four different values of a one ton CO2 reduction (model average

  social cost of carbon, each value increases over time. For the purposes of this table, we show the benefits
  associated with the model average at 3 percent discount rate, however we emphasize the importance and value of
  considering the full range of social cost of carbon values. We provide combined climate and health estimates
  based on additional discount rates in the RIA.

    The EPA has used the social cost of carbon (SC-CO2) 
estimates presented in the Technical Support Document: Technical Update 
of the Social Cost of Carbon for Regulatory Impact Analysis Under 
Executive Order 12866 (May 2013, Revised July 2015) (``current TSD'')

estimates, which were developed by the U.S. government, as ``SC-
CO2 estimates.'' The SC-CO2 is a metric that 
estimates the monetary value of impacts associated with marginal 
changes in CO2 emissions in a given year. It includes a wide 
range of anticipated climate impacts, such as net changes in 
agricultural productivity and human health, property damage from 
increased flood risk, and changes in energy system costs, such as 
reduced costs for heating and increased costs for air conditioning. It 
is typically used to assess the avoided damages as a result of 
regulatory actions (i.e., benefits of rulemakings that lead to an 
incremental reduction in cumulative global CO2 emissions).

    The SC-CO2 estimates used in this analysis were 
developed over many years, using the best science available, and with 
input from the public. Specifically, an interagency working group (IWG) 
that included the EPA and other executive branch agencies and offices 
used three integrated assessment models (IAMs) to develop the SC-
CO2 estimates and recommended four global values for use in 
regulatory analyses. The SC-CO2 estimates were first 
released in February 2010 and updated in 2013 using new versions of 
each IAM. The 2010 SC-CO2 Technical Support Document (2010 
TSD) \130\ provides a complete discussion of the methods used to 
develop these estimates and the current TSD presents and discusses the 
2013 update (including two recent minor corrections to the 
estimates).\131\

    OMB's Office of Information and Regulatory Affairs received 
comments in response to a request for public comment on the approach 
used to develop the estimates. After careful evaluation of the full 
range of comments submitted to OMB, the IWG continues to recommend the 
use of the SC-CO2 estimates in RIA.\132\ With the release of 
the response to comments, the IWG announced plans to obtain expert 
independent advice from the National Academies of Sciences, 
Engineering, and Medicine (Academies) to ensure that the SC-
CO2 estimates continue to reflect the best available 
scientific and economic information on climate change. The Academies 
review will be informed by the public comments received and focus on 
the technical merits and challenges of potential approaches to 
improving the SC-CO2 estimates in future updates. See the 
EPA Response to Comments document for the complete response to comments 
received on SC-CO2 as part of this rulemaking.
---------------------------------------------------------------------------

    \132\ See https://www.whitehouse.gov/omb/oira/social-cost-of-carbon for additional details, including the OMB Response to 
Comments and the SC-CO2 TSDs.
---------------------------------------------------------------------------

    Concurrent with OMB's publication of the response to comments on 
SC-CO2 and announcement of the Academies process, OMB posted 
a revised TSD that includes two minor technical corrections to the 
current estimates. One technical correction addressed an inadvertent 
omission of climate change damages in the last year of analysis (2300) 
in one model and the second addressed a minor indexing error in another 
model. On average the revised SC-CO2 estimates are one 
dollar less than the mean SC-CO2 estimates reported in the 
November 2013 revision to the May 2013 TSD. The change in the estimates 
associated with the 95th percentile estimates when using a 3 percent 
discount rate is slightly larger, as those estimates are heavily 
influenced by the results from the model that was affected by the 
indexing error.
    The EPA, as a member of the IWG on the SC-CO2, has 
carefully examined and evaluated the minor technical corrections in the 
revised TSD and the public comments submitted to OMB's SC-
CO2 comment process. The EPA concurs with the IWG's 
conclusion that it is reasonable, and scientifically appropriate, to 
use the current SC-CO2 estimates for purposes of RIA, 
including for this proceeding.
    The four SC-CO2 estimates are as follows: $12, $40, $60, 
and $120 per short ton of CO2 emissions in the year 2020 
(2011$).\133\ The first three values are based on the average SC-
CO2 from the three IAMs, at discount rates of 5, 3, and 2.5 
percent, respectively. The SC-CO2 value at several discount 
rates are included because the literature shows that the SC-
CO2 is quite sensitive to assumptions about the discount 
rate, and because no consensus exists on the appropriate rate to use in 
an intergenerational context (where costs and benefits are incurred by 
different generations). The fourth value is the 95th percentile of the 
SC-CO2 from all three models at a 3 percent discount rate. 
It is included to represent higher-than-expected impacts from 
temperature change further out in the tails of the SC-CO2 
distribution (representing less likely, but potentially catastrophic, 
outcomes).
---------------------------------------------------------------------------

    \133\ The current version of the TSD is available at: https://www.whitehouse.gov/sites/default/files/omb/inforeg/scc-tsd-final-july-2015.pdf. The 2010 and 2013 TSDs present SC-CO2 in 
2007$ per metric ton. The estimates were adjusted to (1) Short tons 
for using conversion factor 0.90718474 and (2) 2011$ using Gross 
Domestic Product and Related Price Measures: Indexes and Percent 
Changes, http://www.gpo.gov/fdsys/pkg/ECONI-2013-02/pdf/ECONI-2013-02-Pg3.pdf.
---------------------------------------------------------------------------

    There are limitations in the estimates of the benefits from this 
proposal, including the omission of climate and other CO2 
related benefits that could not be monetized. The 2010 TSD discusses a 
number of limitations to the SC-CO2 analysis, including the 
incomplete way in which the IAMs capture catastrophic and non-
catastrophic impacts, their incomplete treatment of adaptation and 
technological change, uncertainty in the extrapolation of damages to 
high temperatures, and assumptions regarding risk aversion. Currently, 
IAMs do not assign value to all of the important impacts of 
CO2 recognized in the literature, such as ocean 
acidification or potential tipping points, for various reasons, 
including the inherent difficulties in valuing non-market impacts and 
the fact that the science incorporated into these models understandably 
lags behind the most recent research. Nonetheless, these estimates and 
the discussion of their limitations represent the best available 
information about the social benefits of CO2 emission 
reductions to inform the benefit-cost analysis. As previously noted, 
the IWG plans to seek

[[Page 65047]]

independent expert advice on technical opportunities to improve the SC-
CO2 estimates from the Academies. The Academies' process 
will help to ensure that the SC-CO2 estimates used by the 
federal government continue to reflect the best available science and 
methodologies. Additional details are provided in the TSDs.
    The health co-benefits estimates represent the total monetized 
human health benefits for populations exposed to reduced 
PM2.5 and ozone resulting from emission reductions from the 
federal plan approaches examined in the RIA for this proposal. Unlike 
the global SC-CO2 estimates, the air pollution health co-
benefits are estimated for the contiguous United States only. We used a 
``benefit-per-ton'' approach to estimate the benefits of this 
rulemaking. To create the PM2.5 benefit-per-ton estimates, 
we conducted air quality modeling for an illustrative scenario 
reflecting the proposed Clean Power Plan EGs to convert precursor 
emissions into changes in ambient PM2.5 and ozone 
concentrations. We then used these air quality modeling results in 
BenMAP \134\ to calculate average regional benefit-per-ton estimates 
using the health impact assumptions used in the PM NAAQS RIA \135\ and 
Ozone NAAQS RIAs.136 137 The three regions were the Eastern 
United States, Western United States, and California. To calculate the 
co-benefits for this proposal, we multiplied the regional benefit-per-
ton estimates generated from modeling of the proposed Clean Power Plan 
EGs standards by the corresponding regional emission reductions for 
this proposal.\138\ All benefit-per-ton estimates reflect the 
geographic distribution of the modeled emissions for the proposed Clean 
Power Plan EGs, which may not exactly match the emission reductions in 
this proposed rulemaking, and thus they may not reflect the local 
variability in population density, meteorology, exposure, baseline 
health incidence rates, or other local factors for any specific 
location. More information regarding the derivation of the benefit-per-
ton estimates is available in the Clean Power Plan Final Rule RIA.

    PM benefit-per-ton values are generated using two concentration-
response functions, Krewski et al. (2009) \139\ and Lepeule et al. 
(2012).\140\ These models assume that all fine particles, regardless of 
their chemical composition, are equally potent in causing premature 
mortality because the scientific evidence is not yet sufficient to 
allow differentiation of effect estimates by particle type. Even though 
we assume that all fine particles have equivalent health effects, the 
benefit-per-ton estimates vary between PM2.5 precursors 
depending on the location and magnitude of their impact on 
PM2.5 concentrations, which drive population exposure.

---------------------------------------------------------------------------

    It is important to note that the magnitude of the PM2.5 
and ozone co-benefits is largely driven by the concentration response 
functions for premature mortality and the value of a statistical life 
used to value reductions in premature mortality. For PM2.5, 
we use two key empirical studies, one based on the American Cancer 
Society cohort study (Krewski et al., 2009) and one based on the 
extended Six Cities cohort study (Lepuele et al., 2012). The 
PM2.5 co-benefits results are presented as a range based on 
benefit-per-ton estimates calculated using the concentration-response 
functions from these two epidemiology studies, but this range does not 
capture the full range of uncertainty inherent in the co-benefits 
estimates. In the RIA for this rule, which is available in the docket, 
we also include PM2.5 co-benefits estimates using benefit-
per-ton estimates based on expert judgments of the effect of 
PM2.5 on premature mortality (Roman et al., 2008) \141\ as a 
characterization of uncertainty regarding the PM2.5-
mortality relationship.

---------------------------------------------------------------------------

    For the ozone co-benefits, we present the results as a range 
reflecting benefit-per-ton estimates which use several different 
concentration-response functions for mortality, with the lower end of 
the range based on a benefit-per-ton estimate using the function from 
Bell et al. (2004) \142\ and the upper end based on a benefit-per-ton 
estimate using the function from Levy et al. (2005).\143\ Similar to 
PM2.5, the range of ozone co-benefits does not capture the 
full range of inherent uncertainty.

---------------------------------------------------------------------------

    In this analysis, in estimating the benefits-per-ton for 
PM2.5 precursors, the EPA assumes that the health impact 
function for fine particles is without a threshold. This is based on 
the conclusions of the EPA's Integrated Science Assessment for 
Particulate Matter,\144\ which evaluated the substantial body of 
published scientific literature, reflecting thousands of epidemiology, 
toxicology, and clinical studies, that documents the association 
between elevated PM2.5 concentrations and adverse health 
effects, including increased premature mortality. This assessment, 
which was twice reviewed by the EPA's independent Science Advisory 
Board, concluded that the scientific literature consistently finds that 
a no-threshold model most adequately portrays the PM-mortality 
concentration-response relationship.

---------------------------------------------------------------------------

    In general, we are more confident in the magnitude of the risks we 
estimate from simulated PM2.5 concentrations that coincide 
with the bulk of the observed PM concentrations in the epidemiological 
studies that are used to estimate the benefits. Likewise, we are less 
confident in the risk we estimate from simulated PM2.5 
concentrations

[[Page 65048]]

that fall below the bulk of the observed data in these studies.
    For this analysis, policy-specific air quality data are not 
available,\145\ and thus, we are unable to estimate the percentage of 
premature mortality associated with this specific rule that is above 
the lowest measured PM2.5 levels (LML) for the two 
PM2.5 mortality epidemiology studies that form the basis for 
our analysis. As a surrogate measure of mortality impacts above the 
LML, we provide the percentage of the population exposed above the LML 
in each of the two studies, using the estimates of baseline projected 
PM2.5 from the air quality modeling for the proposed 
guidelines used to calculate the benefit-per-ton estimates for the EGU 
sector. Using the Krewski et al. (2009) study, 88 percent of the 
population is exposed to annual mean PM2.5 levels at or 
above the LML of 5.8 micrograms per cubic meter ([mu]g/m\3\). Using the 
Lepeule et al. (2012) study, 46 percent of the population is exposed 
above the LML of 8 [mu]g/m\3\. It is important to note that baseline 
exposure is only one parameter in the health impact function, along 
with baseline incidence rates, population, and change in air quality.
---------------------------------------------------------------------------

    \145\ In addition, site-specific emission reductions will depend 
upon how states implement the guidelines.
---------------------------------------------------------------------------

    Every benefit analysis examining the potential effects of a change 
in environmental protection requirements is limited, to some extent, by 
data gaps, model capabilities (such as geographic coverage), and 
uncertainties in the underlying scientific and economic studies used to 
configure the benefit and cost models. Despite these uncertainties, we 
believe the air quality co-benefit analysis for this rule provides a 
reasonable indication of the expected health benefits of the air 
pollution emission reductions for the illustrative analysis of this 
proposed action under a set of reasonable assumptions. This analysis 
does not include the type of detailed uncertainty assessment found in 
the 2012 PM2.5 NAAQS RIA (U.S. EPA, 2012) because we lack 
the necessary air quality input and monitoring data to conduct a 
complete benefits assessment. In addition, using a benefit-per-ton 
approach adds another important source of uncertainty to the benefits 
estimates. The 2012 PM2.5 NAAQS benefits analysis provides 
an indication of the sensitivity of our results to various assumptions.
    We note that the monetized co-benefits estimates shown here do not 
include several important benefit categories, including exposure to 
SO2, NOX, and HAP (e.g., mercury and hydrogen 
chloride), as well as ecosystem effects and visibility impairment. 
Although we do not have sufficient information or modeling available to 
provide monetized estimates for this rule, a qualitative assessment of 
these unquantified benefits is included in the RIA for this proposal. 
In addition, in the RIA for this proposal, we did not estimate changes 
in emissions of directly emitted particles. As a result, quantified 
PM2.5 related benefits are underestimated by a relatively 
small amount. In the RIA for the proposed Clean Power Plan EGs, the 
benefits from reductions in directly emitted PM2.5 were less 
than 10 percent of total monetized health co-benefits across all 
scenarios and years.
    For more information on the benefits analysis, please refer to the 
RIA for this rule, which is available in the rulemaking docket.

IX. Community and Environmental Justice Considerations

    In this section we provide an overview of the actions that the 
agency is taking to help ensure that vulnerable communities are not 
disproportionately impacted by this rulemaking.
    As described in the Executive Summary, climate change is an EJ 
issue. Low-income communities and communities of color already 
overburdened with pollution are likely to be disproportionately 
affected by, and less resilient to, the impacts of climate change. This 
rulemaking will provide broad benefit to communities across the nation, 
as its purpose is to reduce GHGs, the most significant driver of 
climate change. While addressing climate change will provide broad 
benefits, it is particularly beneficial to low-income populations and 
some communities of color (in particular, populations defined jointly 
by ethnic/racial characteristics and geographic location) where people 
are most vulnerable to the impacts of climate change (a more robust 
discussion of the impacts of climate change on vulnerable communities 
is provided in the Executive Order 12898 discussion in section X.J of 
this preamble). While climate change is a global phenomenon, the 
adverse effects of climate change can be very localized, as impacts 
such as storms, flooding, and droughts are experienced in individual 
communities.
    Vulnerable communities also often receive more than their fair 
share of conventional air pollution, with the attendant adverse health 
impacts.
    The changes in electricity generation that will result from this 
rule will further benefit communities by reducing existing air 
pollution that directly contributes to adverse localized health 
effects. These air quality improvements will be achieved through this 
rule because the EGUs that emit the most GHGs also have the highest 
emissions of conventional pollutants, such as SO2, 
NOX, fine particles, and HAP. These pollutants are known to 
contribute to adverse health outcomes, including the development of 
heart and lung diseases, such as asthma and bronchitis, increased 
susceptibility to respiratory and cardiac symptoms, greater numbers of 
emergency room visits and hospital admissions, and premature 
deaths.\146\ The EPA expects that the reductions in utilization of 
higher-emitting units likely to occur during the implementation of 
federal plans will produce significant reductions in emissions of 
conventional pollutants, particularly in those communities already 
overburdened by pollution, which are often low-income communities, 
communities of color, and indigenous communities. These reductions will 
have beneficial effects on air quality and public health, both locally 
and regionally. Further, this rulemaking complements other actions 
already taken by the EPA to reduce conventional pollutant emissions and 
improve health outcomes for overburdened communities.
---------------------------------------------------------------------------

    \146\ Six Common Air Pollutants. http://www.epa.gov/oaqps001/urbanair/.
---------------------------------------------------------------------------

    By reducing millions of tons of CO2 emissions that are 
contributing to global GHG levels and providing strong leadership to 
encourage meaningful reductions by countries across the globe, this 
rule is a significant step to address health and economic impacts of 
climate change that will fall disproportionately on vulnerable 
communities. By reducing millions of tons of conventional air 
pollutants, this proposed rule will lead to better air quality and 
improved health in those communities. In the comment period for the 
Clean Power Plan, we heard from many commenters who recognize and 
welcome those benefits.
    There are other ways in which the actions that result from this 
rulemaking may affect overburdened communities in positive or 
potentially adverse ways and we also heard about these from commenters 
on the EGs.
    While the agency expects overall emission decreases as a result of 
this rulemaking, we recognize that some EGUs may operate more 
frequently. To the extent that we project increases in utilization as a 
result of this rulemaking, we expect these increases to occur generally 
in lower-emitting NGCC units,

[[Page 65049]]

which have minimal or no emissions of SO2 and HAP, lower 
emissions of particulate matter, and much lower emissions of 
NOX compared to higher-emitting steam units. We acknowledge 
the concerns that have been raised on this point, but also the 
difficulty in anticipating prior to plan implementation where those 
impacts might occur. As described below, the EPA intends to conduct an 
assessment of whether and where emission increases may result from plan 
implementation and mitigate adverse impacts, if any, in overburdened 
communities.
    In addition to the many positive anticipated health benefits of 
this rulemaking, it also will increase the use of clean energy and will 
encourage EE. These changes in the electricity generation system, which 
are already occurring, but may be accelerated by this program, are 
expected to have other positive benefits for communities. The 
electricity sector is, and will continue to be, investing more in RE 
and EE. The construction of renewable generation and the implementation 
of EE programs such as residential weatherization will bring investment 
and employment opportunities to the communities where they take place. 
It is important to ensure that all communities share in these benefits. 
And while we estimate that the benefits of this program will greatly 
exceed its costs (as noted in the RIA for this rulemaking), it is also 
important to ensure that to the extent there are increases in 
electricity costs, that those do not fall disproportionately on those 
least able to afford them.
    The EPA has engaged with community groups throughout this 
rulemaking and we received many comments on the issues outlined above 
from community groups, EJ organizations, faith-based organizations, 
public health organizations, and others. This input has informed this 
proposed rulemaking and prompted the EPA to consider other steps that 
the agency can take in the short and long term to consider EJ and 
impacts to communities in federal plan development and implementation.
    It has also prompted us to work with our federal partners to make 
sure that communities have information on federal resources available 
to assist them. We describe these resources below, as well as resources 
that the EPA will be providing to assist communities in accessing EE/RE 
and financial assistance programs.
    Finally, and importantly, we recognize that communities must be 
able to participate meaningfully in the development of this rulemaking. 
In this section, we discuss the steps that the EPA will take to assist 
communities in engaging with the agency throughout the comment period 
of this rulemaking.

A. Proximity Analysis

    The EPA is committed to ensuring that there is no disproportionate, 
adverse impact on overburdened communities as a result of this proposed 
rulemaking. To provide information fundamental to beginning that 
process, the EPA has conducted a proximity analysis for this proposed 
rulemaking that summarizes demographic data on the communities located 
near power plants.\147\ The EPA understands that, in order to prevent 
disproportionately high and adverse human health or environmental 
effects on these communities, both the agency and communities must have 
information on the communities living near facilities, including 
demographic data, and that accessing and using census data files 
requires expertise that some community groups may lack. Therefore, the 
EPA used census data from the American Community Survey (ACS) 2008-2012 
to conduct a proximity analysis that can be used by communities as they 
engage with the agency throughout the comment period of this 
rulemaking. The analysis and its results are presented in the EJ 
Screening Report for the Clean Power Plan, which is located in the 
docket for this rulemaking at EPA-HQ-OAR-2015-0199.
---------------------------------------------------------------------------

    \147\ The proximity analysis was conducted using the EPA's 
environmental justice mapping and screening tool, EJSCREEN.
---------------------------------------------------------------------------

    The proximity analysis provides detailed demographic information on 
the communities located within a 3-mile radius of each affected power 
plant in the United States. Included in the analysis is the breakdown 
by percentage of community characteristics such as income and minority 
status. The analysis shows a higher percentage of communities of color 
and low-income communities living near power plants than national 
averages. It is important to note that the impacts of power plant 
emissions are not limited to a 3-mile radius and the impacts of both 
potential increases and decreases in power plant emissions can be felt 
many miles away. Still, being aware of the characteristics of 
communities closest to power plants is a starting point in 
understanding how changes in the plant's air emissions may affect the 
air quality experienced by some of those already experiencing 
environmental burdens.
    Although overall there is a higher fraction of communities of color 
and low-income populations living near power plants than national 
averages, there are differences between rural and urban power plants. 
There are many rural power plants that are located near small 
communities with high percentages of low-income populations and lower 
percentages of communities of color. In urban areas, nearby communities 
tend to be both low-income communities and communities of color. In 
light of this difference between rural and urban communities proximate 
to power plants and in order to adequately capture both the low-income 
and minority aspects central to environmental justice (EJ) 
considerations, we use the terms ``vulnerable'' or ``overburdened'' 
when referring to these communities. Our intent is for these terms to 
be understood in an expansive sense, in order to capture the full scope 
of communities, including indigenous communities most often located in 
rural areas, that are central to our EJ and community considerations.
    As stated in the Executive Order 12898 discussion located in 
section X.J of this preamble, the EPA believes that all communities 
will benefit from this proposed rulemaking because this action directly 
addresses the impacts of climate change by limiting GHG emissions 
through the establishment of CO2 emission standards for 
existing affected fossil fuel-fired power plants. The EPA also believes 
that the information provided in the proximity analysis will promote 
engagement between vulnerable communities and the agency throughout the 
rulemaking process. In addition to providing the proximity analysis in 
the docket of this rulemaking, the EPA will make it publicly available 
on its Clean Power Plan Communities Portal that will be linked to this 
rulemaking's Web site (http://www.epa.gov/cleanpowerplan). Furthermore, 
the EPA has also created an interactive mapping tool that illustrates 
where power plants are located and provides information on a state 
level. This tool is available at: http://cleanpowerplanmaps.epa.gov/CleanPowerPlan/.

B. Community Engagement in This Rulemaking Process

    The EPA has heard from vulnerable communities throughout the 
outreach process for the Clean Power Plan that it is imperative for 
communities to have an understanding of how rulemakings that target 
climate change work. They expressed a desire to know how these programs 
may benefit their communities and what the potential adverse impacts of 
the rules may be on their communities. We intend to provide

[[Page 65050]]

communities with the information that they need to engage with the 
agency throughout the comment period.
    We have received feedback from communities that public hearings, 
webinars, and in-person meetings are the most effective ways to engage 
with them and to provide them with the information they need to 
understand the rulemaking process. Therefore, for this rulemaking, in 
addition to conducting public hearings for all members of the American 
public, the agency will hold a national webinar for communities in the 
early stages of the comment period. The goal of this webinar will be to 
walk communities through the highlights of the preamble, so they have 
an understanding of how the rulemaking may potentially affect their 
communities and they will have the contextual information they need to 
actively engage with the agency throughout the comment period.
    Additionally, because we received positive feedback on the 
effectiveness of the face-to-face meetings conducted on the regional 
level, each region will be offering an outreach meeting(s) for 
communities. The goal of these meetings is to build a level of 
understanding on this rulemaking to enable vulnerable communities to 
actively engage with the agency throughout the comment period. 
Furthermore, we will follow up on common issues raised during the 
outreach meetings with national conference calls, specifically targeted 
for vulnerable communities.

C. Providing Communities With Access to Additional Resources

    In section V.D of this preamble, we outline that we are seeking 
comment on whether a portion of this set-aside should be targeted to RE 
projects that benefit low-income communities. Furthermore, the EPA is 
seeking comment on how a low-income community should be defined as 
eligible under this set-aside. We also seek comment on how much of the 
set-aside should be designated as targeted at over-burdened 
communities. We also request comment on whether the methods of approval 
and distribution of allowances to projects that benefit low-income 
communities should differ, and if so, in what manner, from the methods 
that are proposed to apply to other RE projects.
    As discussed below, there are also many federal programs that can 
help low-income populations access the benefits of RE and EE, and the 
economic benefits of a cleaner energy economy.
    In the coming months, the EPA will continue to provide information 
and resources for low-income communities on existing federal, state, 
local, and other financial assistance programs to encourage EE/RE 
opportunities that are already available to communities. For example, 
the EPA will provide a catalog of current or recent state and local 
programs that have successfully helped communities adopt EE/RE 
measures. The goal of these resources is to help vulnerable communities 
gain the benefits of this rulemaking. The use of these RE/EE tools can 
also help low-income households reduce their electricity consumption 
and bills.
    Additionally, as part of the resources that we will be providing 
low-income communities, the EPA will provide information on the 
Administration's Partnerships for Opportunity and Workforce and 
Economic Revitalization (POWER) Initative and other programs that 
specifically target economic development assistance to communities 
affected by changes in the coal industry and the utility power 
sector.\148\

D. Federal Programs and Resources Available to Communities

    Federal agencies have a history of bringing EE and RE to low-income 
communities. Earlier this summer, the Administration announced a new 
initiative to scale up access to solar energy and cut energy bills for 
all Americans, in particular low- and moderate-income communities, and 
to create a more inclusive solar workforce. As part of this new 
initiative, the U.S. DOE, the U.S. Department of Housing and Urban 
Development, U.S. Department of Agriculture, and the EPA launched a 
National Community Solar Partnership to unlock access to solar energy 
for the nearly 50 percent of households and businesses that are renters 
or do not have adequate roof space to install solar systems, with a 
focus on low- and moderate-income communities. The Administration also 
set a goal to install 300 MW of RE in federally subsidized housing by 
2020 and plants to provide technical assistance to make it easier to 
install solar energy on affordable housing, including clarifying how to 
use federal funding for EE and RE. To continue enhancing employment 
opportunities in the solar industry for all Americans, AmeriCorps is 
providing funding to deploy solar energy and create jobs in underserved 
communities, and DOE is working to expand solar energy education and 
opportunities for job training.
    These recent announcements build on the many existing federal 
programs and resources available to improve EE and accelerate the 
deployment of RE in vulnerable communities. Some examples of these 
resources include: The DOE's Weatherization Assistance Program, Health 
and Human Service's Low-Income Home Energy Assistance Program, the 
Department of Agriculture's Energy Efficiency and Conservation Loan 
Program, High Cost Energy Grant Program, and the Rural Housing 
Service's Multi-Family Housing Program.
    The U.S. Department of Housing and Urban Development supports EE 
improvements and the deployment of RE on affordable housing through its 
Energy Efficient Mortgage Program, Multifamily Property Assessed Clean 
Energy Pilot with the State of California, PowerSaver Program, and the 
use of Section 108 Community Development Block Grants. The Department 
of Treasury provides several tax credits to support RE development and 
EE in low-income communities, including the New Markets Tax Credit 
Program and the Low-Income Housing Tax Credit. The EPA's RE-Powering 
America's Land Initiative promotes the reuse of potentially 
contaminated lands, landfills and mine sites--many of which are in low-
income communities--for RE through a combination of tailored 
redevelopment tools for communities and developers, as well as site-
specific technical support. The EPA's Green Power Partnership is 
increasing community use of renewable electricity across the country 
and in low-income communities. The EPA partners with EE programs 
throughout the country that leverage ENERGY STAR to deliver broad 
consumer energy-saving benefits, of particular value to low-income 
households who can least afford high energy bills. ENERGY STAR also 
works with houses of worship to reduce energy costs--savings that can 
then be repurposed to their community mission, including programs and 
assistance to residents in low-income communities. The EPA will be 
working with these federal partners and others to ensure that states 
and vulnerable communities have access to information on these programs 
and their resources.
    The federal government also has a number of programs to expand 
employment opportunities in the energy sector, including for 
underserved populations. Examples of these include the U.S. Department 
of Housing and Urban Development, DOE, and the Department of 
Education's ``STEM, Energy, and Economic Development'' program; DOE's 
Diversity in Science and Technology Advances National Clean Energy in 
Solar (DISTANCE-

Deployment (GEARED); the DOL's Trade Adjustment Assistance Community 
College and Career Training (TAACCCT), Apprenticeship USA Advancing 
Apprenticeships in the Energy Field, Job Corps Green Training and 
Greening of Centers, and YouthBuild; and the EPA's Environmental 
Workforce Development and Job Training (EWDJT) program.

E. Assessing Impacts of Federal Plan Implementation

    It is important to the EPA that the implementation of federal plans 
be assessed in order to identify whether they cause any adverse impacts 
on communities already overburdened by disproportionate environmental 
harms and risks. The EPA will conduct its own assessment during the 
implementation phase of this rulemaking to determine whether the 
implementation of federal plans and other air quality rules are, in 
fact, reducing emissions and improving air quality in all areas and, or 
whether there are localized air quality impacts that need to be 
addressed under the Clean other CAA authorities.
    The EPA will provide trainings for communities on resources that 
they can use to assess localized impacts, especially effects of co-
pollutants, of plans on their communities. This training will include 
guidance in accessing the publicly available information that sources 
and states currently report that can help with ongoing assessments of 
federal plan impacts. For example, unit-specific emissions data and air 
quality monitoring data are readily available. This information, 
together with the assessment that the EPA will conduct in the 
implementation phase of this rulemaking will enable the agency and 
communities to monitor any disproportionate emissions that may result 
in adverse impacts and address them.

F. Co-Pollutants

    Air quality in a given area is affected by emissions from nearby 
sources and may be influenced by emissions that travel hundreds of 
miles and mix with emissions from other sources.\149\ In the CSAPR the 
EPA used its authority to reduce emissions that significantly 
contribute to downwind exposures. The RIA for the final CSAPR 
anticipates substantial health benefits for the population across a 
wide region. Similarly, the EPA believes that, like the CSAPR, this 
rulemaking will result in significant health benefits because it will 
reduce co-pollutant emissions of SO2 and NOX on a 
regional and national basis.\150\ Thus, localized increases in 
NOX emissions may well be more than offset by NOX 
decreases elsewhere in the region that produce a net improvement in 
ozone and particulate concentrations across the area.
---------------------------------------------------------------------------

    \149\ 76 FR 48348, August 11, 2011.
    \150\ See 76 FR 48347, August 11, 2011.
---------------------------------------------------------------------------

    Another effect of the final CO2 emission standards for 
affected existing fossil fuel-fired EGUs may be increased utilization 
of other, unmodified EGUs--in particular, high efficiency gas-fired 
EGUs--with relatively low GHG emissions per unit of electrical output. 
These plants may operate more hours during the year and could emit 
pollutants, including pollutants whose environmental effects would be 
localized and regional rather than global as is the case with GHG 
emissions. Changes in utilization already occur in response to energy 
demands and evolving energy sources, but the final CO2 
emission standards for affected existing fossil fuel-fired EGUs can be 
expected to cause more such changes. Increased utilization of solid 
fossil fuel-fired units generally would not increase peak 
concentrations of PM2.5, NOX, or ozone around 
such EGUs to levels higher than those that are already occurring 
because peak hourly or daily emissions generally would not change; 
however, increased utilization may make periods of relatively high 
concentrations more frequent. It should be noted that the gas-fired 
sources likely to be dispatched more frequently have very low emissions 
of primary PM, SO2, and HAP per unit of electrical output 
and that they must continue to comply with other CAA requirements that 
directly address the conventional pollutants, including federal 
emission standards, rules included in SIPs, and conditions in title V 
operating permits, in addition to the guidelines in the final EGs 
rulemaking published elsewhere in this Federal Register. Therefore, 
local (or regional) air quality for these pollutants is not likely to 
be significantly affected. For natural gas-fired EGUs, the EPA found 
that regulation of HAP emissions ``is not appropriate or necessary 
because the impacts due to HAP emissions from such units are negligible 
based on the results of the study documented in the utility RTC.'' 
\151\ Because gas-fired EGUs emit essentially no mercury, increased 
utilization will not increase methyl mercury concentrations in water 
bodies near these affected EGUs. In studies done by DOE/NETL comparing 
cost and performance of coal- and NGCC-fired generation, they assumed 
SO2, NOX, PM (and Hg) emissions to be 
``negligible.'' Their studies predict NOX emissions from a 
NGCC unit to be approximately 10 times lower than a subcritical or 
supercritical coal-fired boiler.\152\ Many, although not all, NGCC 
units are also very well controlled for emissions of NOX 
through the application of after combustion controls such as selective 
catalytic reduction.

G. The EPA's Continued Engagement

    The EPA is committed to helping ensure that this action will not 
have disproportionate adverse human health or environmental effects on 
vulnerable communities. Throughout the implementation phase of this 
rulemaking, the agency will continue to provide trainings and resources 
to assist communities and as they engage with the agency. The EPA, 
through its outreach efforts during the comment period, will continue 
to solicit feedback from communities on what they would like additional 
trainings and resources on.
    As described above, the EPA will assess the impacts of this 
rulemaking during its implementation. The EPA will house this 
assessment, along with the proximity analysis and other information 
generated throughout the implementation process, on its Clean Power 
Plan Communities Portal that will be linked to this rulemaking's Web 
site (http://www.epa.gov/cleanpowerplan). In addition, the EPA has 
expanded its set of resources that are being developed to help 
communities understand the breadth of policy options and programs that 
have successfully brought EE/RE to low-income communities. The EPA is 
committed to continuing its engagement with communities from the 
comment period of this rulemaking through federal plan implementation.
    The EPA consulted its May 2015, Guidance on Considering 
Environmental Justice During the Development of Regulatory Actions, 
when crafting this rulemaking.\153\ A more detailed discussion 
concerning the application of Executive Order 12898 in this rulemaking 
can be found in section X.J of this preamble. A summary of the EPA's 
interactions with communities is

[[Page 65052]]

in the EJ Screening Report for the Clean Power Plan, available in the 
docket of this rulemaking. Furthermore, the EPA's responses to public 
comments, including comments received from communities, are provided in 
the response to comments documents located in the docket for this 
rulemaking.

Development of Regulatory Actions. http://www.epa.gov/environmentaljustice/resources/policy/considering-ej-in-rulemaking-guide-final.pdf. May 2015.
---------------------------------------------------------------------------

    In summary, the EPA in this proposed rulemaking has designed an 
integrative approach that helps to ensure that vulnerable communities 
are not disproportionately impacted by this rule. The proximity 
analysis that the agency has conducted is a central component of this 
approach. Not only is the proximity analysis a useful tool to help 
identify communities that may be impacted by this rulemaking; it will 
also help communities as they engage with the EPA throughout the 
comment period. It will help the EPA as we help low-income communities 
access EE/RE and financial assistance programs. Finally, in order to 
continue to ensure that overburdened communities are not 
disproportionately impacted by this rule, the EPA will be conducting an 
assessment during the implementation phase of the effects of this and 
other rules on air quality.

X. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at http://www2.epa.gov/laws-regulations/laws-and-executive-orders.

A. Executive Order 12866: Regulatory Planning and Review and Executive 
Order 13563: Improving Regulation and Regulatory Review

    This proposed action is an economically significant regulatory 
action that was submitted to the OMB for review. Any changes made in 
response to OMB recommendations have been documented in the docket for 
this rulemaking. The EPA prepared an analysis of the potential costs 
and benefits associated with this action. This analysis, which is 
contained in the ``Regulatory Impact Analysis for the Proposed Federal 
Plan Requirements for Greenhouse Gas Emissions from Electric Utility 
Generating Units Constructed on or Before January 8, 2014; Model 
Trading Rules; Amendments to Framework Regulations'' (EPA-452/R-15-006, 
July 2015), is available in the docket and is briefly summarized in 
section VIII of this preamble.
    Consistent with Executive Order 12866 and Executive Order 13563, 
the EPA estimated the costs and benefits for two alternative federal 
plan approaches to implementing the proposed federal plan and model 
trading rules. The proposed action will achieve the same levels of 
emissions performance as required of state plans under the CAA section 
111(d) EGs for the control of CO2. Actions taken to comply 
with the guidelines will also reduce the emissions of directly-emitted 
PM2.5, SO2, and NOX. The benefits 
associated with these PM2.5, SO2, and 
NOX reductions are referred to as co-benefits, as these 
reductions are not the primary objective of this rule.
    The RIA for this proposal analyzed two implementation scenarios, 
which we term the ``rate-based federal plan approach'' and the ``mass-
based federal plan approach.'' It is very important to note that the 
differences between the analytical results for the rate-based and mass-
based federal plan approaches presented in the RIA may not be 
indicative of likely differences between the approaches. In other 
words, if one approach performs differently than the other on a given 
metric during a given time period, this does not imply this will apply 
in all instances.
    It is important to note that the potential regulatory impacts 
presented in the Clean Power Plan Final Rule RIA and the RIA for this 
proposed rule are not additive. Both RIAs present estimates of the 
benefits and costs of achieving the emission performance rates of the 
Clean Power Plan EGs. In the case of the Clean Power Plan Final Rule 
RIA, the illustrative analysis assumes the performance rates are met 
under state plans. In the case of this RIA for the proposed federal 
plan and model trading rules, the same performance rates are 
accomplished but are assumed to be achieved under the federal plan or 
model trading rules.
    The EPA has used the social cost of carbon estimates presented in 
the Technical Support Document: Technical Update of the Social Cost of 
Carbon for Regulatory Impact Analysis Under Executive Order 12866 (May 
2013, Revised July 2015) (``current TSD'') to analyze CO2 
climate impacts of this rulemaking. We refer to these estimates, which 
were developed by the U.S. government, as ``SC-CO2 
estimates.'' The SC-CO2 is an estimate of the monetary value 
of impacts associated with a marginal change in CO2 
emissions in a given year. The four SC-CO2 estimates are 
associated with different discount rates (model average at 2.5 percent 
discount rate, 3 percent, and 5 percent; 95th percentile at 3 percent), 
and each increases over time. In this summary, the EPA provides the 
estimate of climate benefits associated with the SC-CO2 
value deemed to be central in the current TSD: The model average at 3 
percent discount rate.
    The EPA estimates that, in 2020, this proposal will yield monetized 
climate benefits (in 2011$) of approximately $2.8 billion for the rate-
based approach and $3.3 billion for the mass-based approach (3 percent 
model average). For the rate-based approach, the air pollution health 
co-benefits in 2020 are estimated to be $0.7 billion to $1.8 billion 
(2011$) for a 3 percent discount rate and $0.64 billion to $1.7 billion 
(2011$) for a 7 percent discount rate. For the mass-based approach, the 
air pollution health co-benefits in 2020 are estimated to be $2.0 
billion to $4.8 billion (2011$) for a 3 percent discount rate and $1.8 
billion to $4.4 billion (2011$) for a 7 percent discount rate. The 
annual compliance costs estimated by IPM and inclusive of DS-EE program 
and participant costs and monitoring, reporting, and recordkeeping 
costs in 2020, are approximately $2.5 billion for the rate-based 
approach and $1.4 billion for the mass-based approach (2011$). The 
quantified net benefits (the difference between monetized benefits and 
compliance costs) in 2020 are estimated to range from $1.0 billion to 
$2.1 billion (2011$) for the rate-based approach and from $3.9 billion 
to $6.7 billion (2011$) for the mass-based approach, using a 3 percent 
discount rate (model average).
    The EPA estimates that, in 2025, the proposal will yield monetized 
climate benefits (in 2011$) of approximately $10 billion for the rate-
based approach and $12 billion for the mass-based approach (3 percent 
model average). For the rate-based approach, the air pollution health 
co-benefits in 2025 are estimated to be $7.4 billion to $18 billion 
(2011$) for a 3 percent discount rate and $6.7 billion to $16 billion 
(2011$) for a 7 percent discount rate. For the mass-based approach, the 
air pollution health co-benefits in 2025 are estimated to be $7.1 
billion to $17 billion (2011$) for a 3 percent discount rate and $6.5 
billion to $16 billion (2011$) for a 7 percent discount rate. The 
annual compliance costs estimated by IPM and inclusive of DS-EE program 
and participant costs and MRR costs in 2025, are approximately $1.0 
billion for the rate-based approach and $3.0 billion for the mass-based 
approach (2011$). The quantified net benefits (the difference between 
monetized benefits and compliance costs) in 2025 are estimated to range 
from $17 billion to $27 billion (2011$) for the rate-based approach and 
$16 billion to $26 billion (2011$) for the mass-based approach, using a 
3 percent discount rate (model average).

[[Page 65053]]

    The EPA estimates that, in 2030, the proposal will yield monetized 
climate benefits (in 2011$) of approximately $20 billion for the rate-
based approach and $20 billion for the mass-based approach (3 percent 
model average). For the rate-based approach, the air pollution health 
co-benefits in 2030 are estimated to be $14 billion to $34 billion 
(2011$) for a 3 percent discount rate and $13 billion to $31 billion 
(2011$) for a 7 percent discount rate. For the mass-based approach, the 
air pollution health co-benefits in 2030 are estimated to be $12 
billion to $28 billion (2011$) for a 3 percent discount rate and $11 
billion to $26 billion (2011$) for a 7 percent discount rate. The 
annual compliance costs estimated by IPM and inclusive of DS-EE program 
and participant costs and monitoring, reporting, and recordkeeping 
costs in 2030, are approximately $8.4 billion for the rate-based 
approach and $5.1 billion for the mass-based approach (2011$). The 
quantified net benefits (the difference between monetized benefits and 
compliance costs) in 2030 are estimated to range from $26 billion to 
$45 billion (2011$) for the rate-based approach and from $26 billion to 
$43 billion (2011$) for the mass-based approach, using a 3 percent 
discount rate (model average).
    Table 18 and Table 19 of this preamble provide the estimates of the 
climate benefits, health co-benefits, compliance costs and net benefits 
of the proposal for rate-based and mass-based federal plan approaches, 
respectively.

\b\ The climate benefit estimate in this summary table reflects global impacts from CO2 emission changes and does not account for changes in non-CO2 GHG
  emissions. Also, different discount rates are applied to SC-CO2 than to the other estimates because CO2 emissions are long-lived and subsequent
  damages occur over many years. The benefit estimates in this table are based on the average SC-CO2 estimated for a 3 percent discount rate. However,
  we emphasize the importance and value of considering the full range of SC-CO2 values. As shown in the RIA, climate benefits are also estimated using
  the other three SC-CO2 estimates (model average at 2.5 percent discount rate, 3 percent, and 5 percent; 95th percentile at 3 percent). The SC-CO2
  estimates are year-specific and increase over time.
\c\ The air pollution health co-benefits reflect reduced exposure to PM2.5 and ozone associated with emission reductions of SO2 and NOX. The range
  reflects the use of concentration-response functions from different epidemiology studies. The co-benefits do not include the benefits of reductions in
  directly emitted PM2.5. These additional benefits would increase overall benefits by a few percent based on the analyses conducted for the Clean Power
  Plan proposed rule. The reduction in premature fatalities each year accounts for over 98 percent of total monetized co-benefits from PM2.5 and ozone.
  These models assume that all fine particles, regardless of their chemical composition, are equally potent in causing premature mortality because the
  scientific evidence is not yet sufficient to allow differentiation of effect estimates by particle type.
\d\ Costs are approximated by the compliance costs estimated using the IPM for this proposal and a discount rate of approximately 5 percent. This
  estimate includes monitoring, recordkeeping, and reporting costs and DS-EE program and participant costs.
\e\ The estimates of net benefits in this summary table are calculated using the global SC-CO2 at a 3 percent discount rate (model average). The RIA
  includes combined climate and health estimates based on additional discount rates.

    There are additional important benefits that the EPA could not 
monetize. Due to current data and modeling limitations, our estimates 
of the benefits from reducing CO2 emissions do not include 
important impacts like ocean acidification or potential tipping points 
in natural or managed ecosystems. Unquantified benefits also include 
climate benefits from reducing emissions of non-CO2 GHGs 
(e.g., nitrous oxide and methane) and co-benefits from reducing direct 
exposure to SO2, NOX, and HAP (e.g., mercury), as 
well as from reducing ecosystem effects and visibility impairment. 
Based upon the foregoing discussion, it remains clear that the benefits 
of this proposed action are substantial, and far exceed the costs. 
Additional details on benefits, costs, and net benefits estimates are 
provided in the RIA for this proposal.

B. Paperwork Reduction Act (PRA)

    The information collection requirements in this rule have been 
submitted for approval to OMB under the PRA. The Information Collection 
Request (ICR) document prepared by the EPA has been assigned EPA ICR 
number 2526.01. You can find a copy of the ICR in the docket for this 
rule, and it is briefly summarized here. The information collection 
requirements are not enforceable until approved by OMB.
    This rule does not directly impose specific requirements on state 
and U.S. territory governments with affected EGUs. The rule also does 
not impose specific requirements on tribal governments that have 
affected EGUs located in their area of Indian country. This rule does 
impose specific requirements on affected EGUs located in states, U.S. 
territories, or areas of Indian country.
    The information collection activities in this proposed rule are 
consistent with those activities defined under the Carbon Pollution 
Emission Guidelines for Existing Stationary Sources: Electric Utility 
Generating Units (i.e., the Clean Power Plan) finalized on August 3, 
2015. The information collection requirements in this proposed rule 
have been submitted for approval to the Office of Management and Budget 
(OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. The ICR 
document prepared by the EPA has been assigned EPA ICR number 2526.01. 
You can find a copy of the ICR in the docket for this rule, and it is 
briefly summarized here.
    Aside from reading and understanding the rule, this proposed action 
would impose minimal new

[[Page 65055]]

information collection burden on affected EGUs beyond what those 
affected EGUs would already be subject to under the authorities of 40 
CFR parts 75 and 98. OMB has previously approved the information 
collection requirements contained in the existing part 75 and 98 
regulations (40 CFR part 75 and 40 CFR part 98) under the provisions of 
the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. and has assigned 
OMB control numbers 2060-0626 and 2060-0629, respectively. Apart from 
certain reporting costs based on requirements in the NSPS General 
Provisions (40 CFR part 60, subpart A), which are mandatory for all 
owners/operators subject to CAA section 111 national emission 
standards, there are no new information collection costs, as the 
information required by this proposed rule is already collected and 
reported by other regulatory programs. The recordkeeping and reporting 
requirements are specifically authorized by CAA section 114 (42 U.S.C. 
7414). All information submitted to the EPA pursuant to the 
recordkeeping and reporting requirements for which a claim of 
confidentiality is made is safeguarded according to agency policies set 
forth in 40 CFR part 2, subpart B.
    Although the EPA cannot determine at this time how many affected 
EGU respondents will submit information under the federal plan, the EPA 
has estimated an ``upper bound'' burden estimate for this ICR that 
estimates burden should every affected EGU read and understand the 
rule. This is the only potential respondent activity that would be 
required under the 3-year period following publication of the final 
federal plan, as there are no obligations to respond in this period. 
The results of this upper bound estimate of federal plan burden are 
presented below:
    Respondents/affected entities: 1,028.
    Respondents' obligation to respond: Not applicable, no responses 
are required during the period covered by the ICR.
    Estimated number of respondents: Unknown at this time, but have 
assumed all affected entities are respondents for an upper bound 
estimate.
    Frequency of response: None, no responses are required during the 
period covered by the ICR.
    Total estimated burden: 17,133 hours (per year). Burden is defined 
at 5 CFR 1320.3(b).
    Total estimated cost: $1,706,501 (per year).
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for the 
EPA's regulations in 40 CFR are listed in 40 CFR part 9.
    Submit your comments on the agency's need for this information, the 
accuracy of the provided burden estimates, and any suggested methods 
for minimizing respondent burden to the EPA using the docket identified 
at the beginning of this rule. You may also send your ICR-related 
comments to OMB's Office of Information and Regulatory Affairs via 
email to oria_submissions@omb.eop.gov, Attention: Desk Officer for the 
EPA. Since OMB is required to make a decision concerning the ICR 
between 30 and 60 days after receipt, OMB must receive comments no 
later than November 23, 2015. The EPA will respond to any ICR-related 
comments in the final rule.

C. Regulatory Flexibility Act (RFA)

    Pursuant to section 603 of the RFA, the EPA prepared an initial 
regulatory flexibility analysis (IRFA) that examines the impact of the 
proposed rule on small entities along with regulatory alternatives that 
could minimize that impact. The complete IRFA is available for review 
within the RIA in docket EPA-HQ-OAR-2015-0199 and is summarized here.
    The small entities subject to the requirements of this proposed 
rule may include privately-owned and publicly-owned entities, and rural 
electric cooperatives that are majority owners of affected EGUs. The 
EPA conducted this regulatory flexibility analysis at the highest level 
of ownership, evaluating parent entities with the largest share of 
ownership in at least one potentially-affected EGU included in EPA's 
Base Case using the IPM v.5.15, used in the RIA for this proposed rule. 
This analysis drew on parsed unit-level estimates using IPM results for 
2030.
    The EPA identified 223 potentially affected EGUs owned by 74 small 
entities included in 2030 projections from EPA's IPM v.5.15. Fifty-nine 
of these potentially affected EGUs are projected to no longer be 
operating by 2030 in the Base Case of EPA's version of IPM. Twenty-four 
small entities are projected to have all of their potentially affected 
EGUs cease operation by 2030 in this base case.
    The EPA estimated net compliance costs for individual EGUs for the 
proposed rule using components for operating and annualized capital 
costs, fuel costs, demand-side energy efficiency program costs, and 
revenue changes. This approach is consistent with previous proposed 
power sector regulations, but also adds the additional component of 
change in demand-side energy efficiency program costs. Investment in 
demand-side energy efficiency results in lower electricity demand, and 
consequently fewer emissions as production is reduced to meet the lower 
demand, an important emission-reduction strategy modeled in the rate-
based and mass-based federal plan approaches. For this analysis, the 
EPA used the parsed unit-level estimates to estimate three of the four 
components of the net compliance cost equation using IPM outputs: The 
change in operating and annualized capital costs, the change in fuel 
costs, and the change in revenue, where all changes are estimated as 
the difference between the base case and federal plan scenario. These 
impacts were then summed for each small entity, adjusting for ownership 
share. An additional analysis was performed outside of EPA's IPM model 
to estimate the change in demand-side energy efficiency program costs, 
based largely on IPM-projected outputs.
    As noted earlier, there are 74 small entities with potentially 
affected EGUs that are modeled in the IPM base case in 2030. Of these, 
24 small entities are projected to withdraw all of their potentially 
affected EGUs from operation under base case conditions. This leaves 50 
small entities with potentially affected EGUs that are projected to be 
generating electricity in 2030. Under the rate-based federal plan 
approach, 7 of these 50 small entities are projected to withdraw all of 
their potentially affected EGUs from operation by 2030. Under the mass-
based federal plan approach, 5 of these 50 small entities are projected 
withdraw all of their potentially affected EGUs from operation by 2030.
    Under the rate-based federal plan approach, 23 small entities are 
projected to incur net compliance costs greater than 3 percent of 
generation revenues from their potentially affected EGUs. In contrast, 
9 entities are estimated to have net compliance cost savings greater 
than 3 percent of their generation revenues from affected EGUs. Under 
the mass-based federal plan approach, 21 small entities are projected 
to incur net compliance costs greater than 3 percent of generation 
revenues from their potentially affected EGUs. In contrast, 11 entities 
are estimated to have net compliance cost savings greater than 3 
percent of generation revenues from their affected EGUs.
    There are uncertainties and limitations in this analysis that may 
result in estimates that diverge from what we might see in reality. For 
example, at the time of this proposal,

[[Page 65056]]

the EPA has no information on whether any or how many states will 
require a federal plan. The rate-based and mass-based federal plan 
approaches analyzed in this IRFA are based on a scenario where all 
states of the contiguous United States will be regulated under a 
federal plan. Another factor to consider is that entities operating in 
regulated or cost-of-service markets are likely able to recover 
compliance costs through rate adjustments; as a result these costs can 
be viewed as likely being over-estimates for this set of utilities. 
Other uncertainties and data limitations exist and are described in the 
complete IRFA available for review within the RIA for this proposal.
    As discussed earlier in this preamble, the reporting, recordkeeping 
and other compliance requirements are most likely covered under 40 CFR 
part 75 and part 98 programs for affected EGUs. Therefore, only a 
marginal additional cost is expected for the monitoring, reporting and 
recordkeeping requirements of the proposed federal plan for affected 
EGUs.
    Owners of affected EGUs may be subject to other related rules. For 
example, on September 20, 2013, the EPA proposed carbon pollution 
standards for new fossil fuel fired EGUs. On June 2, 2014, the EPA 
proposed carbon pollution standards for modified and reconstructed 
fossil fuel-fired EGUs, in addition to the Clean Power Plan EGs, to cut 
carbon pollution from existing fossil fuel-fired EGUs. These existing 
EGUs are, or will be, potentially impacted by several other recently 
finalized EPA rules. On February 16, 2012, the EPA issued the mercury 
and air toxics standards (MATS) rule (77 FR 9304) to reduce emissions 
of toxic air pollutants from new and existing coal- and oil-fired EGUs. 
On May 19, 2014, the EPA issued a final rule under section 316(b) of 
the Clean Water Act (33 U.S.C. 1326(b)). This rule establishes new 
standards to reduce injury and death of fish and other aquatic life 
caused by cooling water intake structures at existing power plants and 
manufacturing facilities. On June 18, 2014 (79 FR 34830), the EPA 
promulgated the stream electric effluent limitation guidelines (SE ELG) 
rule to strengthen the controls on discharges from certain steam 
electric power plants. On April 17, 2015 (80 FR 21302), the EPA 
promulgated the coal combustion residuals (CCR) rule, which establishes 
technical requirements for CCR landfills and surface impoundments under 
subtitle D of the Resource Conservation and Recovery Act (RCRA), the 
nation's primary law for regulating solid waste.
    As required by section 609(b) of the RFA, the EPA also convened a 
Small Business Advocacy Review (SBAR) Panel to obtain advice and 
recommendations from small entity representatives that potentially 
would be subject to the rule's requirements. The SBAR Panel evaluated 
the assembled materials and small-entity comments on issues related to 
elements of an IRFA. A copy of the full SBAR Panel Report is available 
in the rulemaking docket.
    The EPA also considered whether the separate changes that we are 
proposing to make, as explained in section VII of this preamble, to the 
framework regulations in subpart B of part 60 of the CAA regulations 
would have any impacts on small entities. Since these changes only 
modify and enhance the procedures that the Administrator will follow in 
processing state plans and promulgating a federal plan, and do not 
alter the rules or requirements that states or regulated entities must 
follow, the agency does not believe that there will be economic impacts 
on small entities from this portion of this proposal. After considering 
the economic impacts of the proposed changes to 40 CFR 60.27, I certify 
those changes will not have a significant economic impact on a 
substantial number of small entities.

D. Unfunded Mandates Reform Act (UMRA)

    This action contains a federal mandate under UMRA, 2 U.S.C. 1531-
1538, that could potentially result in expenditures of $100 million or 
more for state, local, and tribal governments, in the aggregate, or the 
private sector in any 1 year. This federal plan will apply only to 
those affected EGUs located in states that do not submit approvable 
state plans, which is a subset of the EGUs considered in the RIA for 
the final EGs (see RIA for this proposal for further discussion of 
impacts). Because it is impossible to determine at this time which 
states might be ultimately subject to a federal plan, the EPA cannot 
determine whether this rule, when finalized, will be subject to UMRA. 
However, as noted below, the agency has done substantial outreach to 
government entities as part of both the federal plan and the related 
CAA section 111(d) rulemaking. Further, regardless of whether the EPA 
does determine that this action ultimately meets the UMRA threshold, 
the agency intends to do additional outreach with government entities 
between now and the final rule. Additionally, the EPA has determined 
that this action is not subject to the requirements of section 203 of 
UMRA because it contains no regulatory requirements that might 
significantly or uniquely affect small governments.
    Nevertheless, the EPA is aware that there is substantial interest 
in this rule among small entities (e.g., municipal and rural electric 
cooperatives). In light of this interest, prior to this action, the EPA 
sought early input from representatives of small entities while 
formulating the provisions of the proposed regulation. Such outreach is 
also consistent with the President's January 18, 2011 Memorandum on 
Regulatory Flexibility, Small Business, and Job Creation, which 
emphasizes the important role small businesses play in the American 
economy. This outreach process has enabled the EPA to hear directly 
from these representatives, as the EPA developed the rule about how the 
EPA should approach the complex question of how to apply section 111 of 
the CAA to the regulation of GHGs from these source categories. We 
invite comments on all aspects of this proposal and its impacts, 
including potential adverse impacts, on small entities.

E. Executive Order 13132: Federalism

    The EPA believes that this proposed rule may be of significant 
interest to state and local governments due to its relationship with 
the Clean Power Plan EGs. Therefore, the EPA has determined that 
consultations with state and local governments conducted during the 
Clean Power Plan EGs development process are also relevant to this 
proposed rule. Consistent with the EPA's policy to promote 
communications between the EPA and state and local governments, the EPA 
consulted with state and local officials early in the process of 
developing the Clean Power Plan EGs to permit them to have meaningful 
and timely input into its development. As described in the Federalism 
discussion in the preamble to the proposed standards of performance for 
GHG emissions from new EGUs (79 FR 1501; January 8, 2014), the EPA 
consulted with state and local officials in the process of developing 
the proposed standards for newly constructed EGUs. A detailed 
Federalism Summary Impact Statement (FSIS) describing the most pressing 
issues raised in pre-proposal and post-proposal comments will be 
forthcoming with the final Clean Power Plan EGs, as required by section 
6(b) of Executive Order 13132. In the spirit of Executive Order 13132, 
and consistent with the EPA's policy to promote communications between 
the EPA and state and local governments, the EPA specifically solicits 
comment on this

[[Page 65057]]

proposed action from state and local officials.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    This proposed action has tribal implications. However, it will 
neither impose substantial direct compliance costs on federally 
recognized tribal governments, nor preempt tribal law. The EGUs 
potentially impacted by this proposed rulemaking located on Indian 
reservations are primarily owned by private entities, and in one case, 
partially owned by an agency of the U.S. government. As a result, the 
tribes on whose areas of Indian country those units are located will 
not be directly impacted by any costs of complying with this proposed 
rulemaking incurred by the owners/operators of those units. There would 
only be tribal implications in regards to compliance costs associated 
with this proposed rulemaking in the case where a tribal government has 
an ownership interest in a potentially affected EGU. A tribal 
government could also incur costs in the event that it seeks and is 
given delegated authority to enforce the federal plan proposed in this 
rulemaking. The EPA has, nevertheless, offered consultation to the 
tribes on whose areas of Indian country the units are located. As part 
of its general outreach to tribes regarding this proposed rulemaking, 
the EPA received feedback from a number of tribes regarding the 
potential overall economic impact that both the proposed Clean Power 
Plan and a proposed federal plan rulemaking may have on them. In these 
instances, the EPA has reached out to these tribes and as part of the 
consultation on the Clean Power Plan engaged with them on their 
concerns regarding a potential federal plan.
    The EPA has conducted consultation with tribes on the Clean Power 
Plan and the Supplemental Proposal for the Clean Power Plan and will 
offer all tribes consultation on this proposed action. The EPA held 
consultations with tribes on the Clean Power Plan in the fall of 2014 
before the agency issued its Supplemental Proposal for Indian country 
and U.S. Territories. Additionally, the EPA held consultations for 
tribes shortly following the release of the supplemental proposal. The 
agency also held a public hearing on the supplemental proposal on 
November 19, 2014, in Phoenix, Arizona. At the public hearing the 
agency received oral comments from community members representing a 
number of tribes and a number of tribal officials. The agency also 
conducted consultations with tribes in the spring and summer of 2015. 
An overview of the consultations provided as part of the Clean Power 
Plan is available in section XII.F of the final EGs.
    Additionally, the EPA engaged in meaningful dialogue with tribal 
stakeholders to obtain their feedback in the pre-proposal stages of 
this rulemaking. We provided an update on this proposed rulemaking on 
the May 28, 2015, National Tribal Air Association and the EPA Air 
Policy call. Staff attended the National Tribal Forum conference on May 
20, 2015 and provided an overview of the Clean Power Plan and explained 
that the agency would be proposing a federal plan.
    Consistent with previous rulemakings impacting the power sector, 
there is significant tribal interest in these rulemakings because of 
the potential indirect impacts that rules such as the Clean Power Plan 
and this proposed federal plan may have on tribes. The EPA specifically 
solicits additional feedback from tribal officials on all aspects of 
this proposed rulemaking, including whether tribes whose areas of 
Indian country contain affected EGU(s) are interested in developing 
their own plan implementing the final EGs. Additionally, tribal 
stakeholders will be included in the outreach that the agency will be 
conducting with those communities already overburdened by pollution, 
which are often low-income communities, communities of color, and 
indigenous communities. The actions that the agency will be taking are 
outlined in section IX of this preamble.

G. Executive Order 13045: Protection of Children From Environmental 
Health Risks and Safety Risks

    The EPA interprets EO 13045 (62 FR 19885; April 23, 1997) as 
applying to those regulatory actions that concern health or safety 
risks, such that the analysis required under section 5-501 of the Order 
has the potential to influence the regulation. This action is not 
subject to EO 13045 because it does not involve decisions on 
environmental health or safety risks that may disproportionately affect 
children. The EPA believes that the CO2 emission reductions 
resulting from implementation of the proposed federal plan, as well as 
substantial ozone and PM2.5 emission reductions as a 
cobenefit, would further improve children's health.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

    This action, which is a significant regulatory action under EO 
12866, is likely to have a significant effect on the supply, 
distribution, or use of energy. The EPA has prepared a Statement of 
Energy Effects for this action as follows. We estimate a 1 to 2 percent 
change in retail electricity prices on average across the contiguous 
United States in 2025, and a 22 to 23 percent reduction in coal-fired 
electricity generation as a result of this rule. The EPA projects that 
utility power sector delivered natural gas prices will increase by up 
to 2.5 percent in 2030. For more information on the estimated energy 
effects, please refer to the economic impact analysis for this 
proposal. The analysis is available in the RIA, which is in the public 
docket.

I. National Technology Transfer and Advancement Act (NTTAA) and 1 CFR 
Part 51

    This proposed action involves technical standards. The EPA proposes 
to recognize ANSI accreditation under ISO 14065 for GHG validation and 
verification bodies as a component of accreditation of independent 
verifiers under both proposed federal plan approachs. The EPA also 
proposes that net energy output measurements must be performed using 
0.2 accuracy class electricity metering instrumentation and calibration 
procedures as specified under ANSI Standards No. C12.20.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629; February 16, 1994) establishes 
federal executive policy on environmental justice (EJ). Its main 
provision directs federal agencies, to the greatest extent practicable 
and permitted by law, to make EJ part of their mission by identifying 
and addressing, as appropriate, disproportionately high and adverse 
human health or environmental effects of their programs, policies, and 
activities on minority populations and low-income populations in the 
United States. The EPA defines EJ as the fair treatment and meaningful 
involvement of all people regardless of race, color, national origin, 
or income with respect to the development, implementation, and 
enforcement of environmental laws, regulations, and policies. The EPA 
has this goal for all communities and persons across this Nation. It 
will be achieved when everyone enjoys the

[[Page 65058]]

same degree of protection from environmental and health hazards and 
equal access to the decision-making process to have a healthy 
environment in which to live, learn, and work.
    Leading up to this rulemaking the EPA summarized the public health 
and welfare effects of GHG emissions in its 2009 Endangerment Finding. 
As part of the Endangerment Finding, the Administrator considered 
climate change risks to minority populations and low-income 
populations, finding that certain parts of the population may be 
especially vulnerable based on their characteristics or circumstances. 
Populations that were found to be particularly vulnerable to climate 
change risks include the poor, the elderly, the very young, those 
already in poor health, the disabled, those living alone, and/or 
indigenous populations dependent on one or a few resources. See 
sections X.F and X.G of this preamble, above, where the EPA discusses 
Consultation and Coordination with Tribal Governments and Protection of 
Children. The Administrator placed weight on the fact that certain 
groups, including children, the elderly, and the poor, are most 
vulnerable to climate-related health effects.
    The record for the 2009 Endangerment Finding summarizes the strong 
scientific evidence in the major assessment reports by the U.S. Global 
Change Research Program, the Intergovernmental Panel on Climate Change 
(IPCC), and the National Research Council of the National Academies 
that the potential impacts of climate change raise EJ issues. These 
reports concluded that poor communities can be especially vulnerable to 
climate change impacts because they tend to have more limited adaptive 
capacities and are more dependent on climate-sensitive resources such 
as local water and food supplies. In addition, Native American tribal 
communities possess unique vulnerabilities to climate change, 
particularly those impacted by degradation of natural and cultural 
resources within established reservation boundaries and threats to 
traditional subsistence lifestyles. Tribal communities whose health, 
economic well-being, and cultural traditions that depend upon the 
natural environment will likely be affected by the degradation of 
ecosystem goods and services associated with climate change. The 2009 
Endangerment Finding record also specifically noted that Southwest 
native cultures are especially vulnerable to water quality and 
availability impacts. Native Alaskan communities are already 
experiencing disruptive impacts, including coastal erosion and shifts 
in the range or abundance of wild species crucial to their livelihoods 
and well-being.
    The most recent assessments continue to strengthen scientific 
understanding of climate change risks to minority populations and low-
income populations in the United States.\154\ The new assessment 
literature provides more detailed findings regarding these populations' 
vulnerabilities and projected impacts they may experience. In addition, 
the most recent assessment reports provide new information on how some 
communities of color may be uniquely vulnerable to climate change 
health impacts in the United States. These reports find that certain 
climate change related impacts--including heat waves, degraded air 
quality, and extreme weather events--have disproportionate effects on 
low-income populations and some communities of color (in particular, 
populations defined jointly by ethnic/racial characteristics and 
geographic location), raising EJ concerns. Existing health disparities 
and other inequities in these communities increase their vulnerability 
to the health effects of climate change. In addition, assessment 
reports also find that climate change poses particular threats to 
health, well-being, and ways of life of indigenous peoples in the 
United States.

---------------------------------------------------------------------------

    As the scientific literature presented above and as the 2009 
Endangerment Finding illustrates, low-income populations and some 
communities of color are especially vulnerable to the health and other 
adverse impacts of climate change. The EPA believes that communities 
will benefit from this proposed federal plan because this action 
directly addresses the impacts of climate change by limiting GHG 
emissions through the establishment of CO2 emission 
standards for existing affected fossil fuel-fired EGUs.
    In addition to reducing CO2 emissions, the guidelines 
finalized in this rulemaking would reduce other emissions from affected 
EGUs that reduce generation due to higher adoption of EE and RE. These 
emission reductions will include SO2 and NOX, 
which form ambient PM2.5 and ozone in the atmosphere, and 
HAP, such as mercury and hydrochloric acid. In the final rule revising 
the annual PM2.5 NAAQS,\155\ the EPA identified low-income 
populations as being a vulnerable population for experiencing adverse 
health effects related to PM exposures. Low-income populations have 
been generally found to have a higher prevalence of pre-existing 
diseases, limited access to medical treatment, and increased 
nutritional deficiencies, which can increase this population's 
susceptibility to PM-related effects.\156\ In areas where this 
rulemaking reduces exposure to PM2.5, ozone, and 
methylmercury, low-income populations will also benefit from such 
emission reductions. The RIA for this rulemaking, included in the 
docket for this rulemaking, provides additional information regarding 
the health and ecosystem effects associated with these emission 
reductions.

    Additionally, as outlined in the community and EJ considerations 
section IX of this preamble, the EPA has taken a number of actions to 
help ensure that this action will not have potential disproportionately 
high and adverse human health or environmental effects on vulnerable 
communities. The EPA consulted its May 2015, Guidance on Considering 
Environmental Justice During the Development of Regulatory Actions, 
when determining what actions to take.\157\ As described in section IX 
of this preamble (community and EJ considerations), the EPA also 
conducted a proximity analysis, which is available in the docket of 
this rulemaking and is discussed in section IX of this preamble. 
Additionally, as outlined in sections I and IX of this preamble the EPA 
has

[[Page 65059]]

engaged meaningfully with communities throughout the development of the 
Clean Power Plan and has devised a robust outreach strategy for 
continual engagement throughout this rulemaking.

60, 62, and 78 of the Code of the Federal Regulations is amended as 
follows:

PART 60--STANDARDS OF PERFORMANCE FOR NEW STATIONARY SOURCES

0
1. The authority citation for part 60 continues to read as follows:

    Authority: 42 U.S.C. 7401 et seq.

0
2. Section 60.27 is amended by:
0
a. Revising paragraphs (b), (c) introductory text, and (c)(1);
0
b. Removing and reserving paragraph (c)(2);
0
c. Revising paragraphs (c)(3), (d), and (e)(1); and
0
d. Adding paragraphs (g) through (k).
    The revisions and additions read as follows:


Sec.  60.27  Actions by the Administrator.

* * * * *
    (b) After receipt of a complete plan or complete plan revision, the 
Administrator will propose the plan or revision for approval or 
disapproval. The Administrator shall, within 12 months after the date 
on which the submission of a complete plan or complete plan revision is 
received, approve or disapprove such plan or revision, or each portion 
thereof.
    (c) The Administrator shall promulgate a federal plan within 12 
months after the date the Administrator:
    (1) Finds the State failed to submit a complete plan or complete 
plan revision within the time prescribed; or
* * * * *
    (3) Disapproves the State plan or plan revision or any portion 
thereof, as unsatisfactory because the requirements of this subpart and 
the applicable emission guidelines have not been met.
    (d) The Administrator will promulgate the regulations under 
paragraph (c) of this section for all or a portion of a federal plan, 
with such modifications as may be appropriate, unless, prior to such 
promulgation, the State has adopted and submitted a plan or plan 
revision which the Administrator approves. After the promulgation of a 
federal plan, the Administrator may approve a State plan or plan 
revision or portion thereof and withdraw all or a portion of the 
federal plan.
    (e)(1) Except as provided in paragraph (e)(2) of this section, 
regulations promulgated by the Administrator under this section will 
prescribe emission standards of the same stringency as the 
corresponding emission guideline(s) specified in the final guideline 
document published under Sec.  60.22(a) and will require final 
compliance with such standards as expeditiously as practicable but no 
later than the times specified in the guideline document.
* * * * *
    (g) Completeness criteria--(1) General. Within 60 days of the 
Administrator's receipt of a state submission, but no later than 6 
months after the date, if any, by which a State is required to submit 
the plan or revision, the Administrator shall determine whether the 
minimum criteria for completeness have been met. Any plan or plan 
revision that a State submits to the EPA, and that has not been 
determined by the EPA by the date 6 months after receipt of the 
submission to have failed to meet the minimum criteria, shall on that 
date be deemed by operation of law to meet such minimum criteria. Where 
the Administrator determines that a plan submission does not meet the 
minimum criteria of this paragraph (g), the State will be treated as 
not having made the submission.
    (2) Administrative criteria. In order to be complete, a State plan 
must contain each of the following administrative criteria:
    (i) A formal letter of submittal from the Governor or her designee 
requesting EPA approval of the plan or revision thereof;
    (ii) Evidence that the State has adopted the plan in the state code 
or body of regulations. That evidence must include the date of adoption 
or final issuance as well as the effective date of the plan, if 
different from the adoption/issuance date;
    (iii) Evidence that the State has the necessary legal authority 
under state law to adopt and implement the plan;
    (iv) A copy of the actual regulation, or document submitted for 
approval and incorporation by reference into the plan. The submittal 
must be a copy of the official state regulation or document signed, 
stamped and dated by the appropriate state official indicating that it 
is fully enforceable by the State. The effective date of the regulation 
or document must, whenever possible, be indicated in the document 
itself. The State's electronic copy must be an exact duplicate of the 
hard copy. For revisions to the approved plan, the submittal must 
indicate the changes made (for example, by redline/strikethrough) to 
the approved plan;
    (v) Evidence that the State followed all of the procedural 
requirements of the state's laws and constitution in conducting and 
completing the adoption and issuance of the plan;
    (vi) Evidence that public notice was given of the proposed change 
with procedures consistent with the requirements of Sec.  60.23, 
including the date of publication of such notice;
    (vii) Certification that public hearing(s) were held in accordance 
with the information provided in the public notice and the State's laws 
and constitution, if applicable and consistent with the public hearing 
requirements in Sec.  60.23;
    (viii) Compilation of public comments and the State's response 
thereto; and
    (ix) Such other criteria for completeness as may be specified by 
the Administrator under the applicable emission guidelines.
    (3) Technical criteria. In order to be complete, a State plan must 
contain each of the following technical criteria:
    (i) Description of the plan approach and geographic scope;
    (ii) Identification of each affected source, identification of 
emission standards for the affected sources, and monitoring, 
recordkeeping and reporting requirements that will determine compliance 
by each affected source;
    (iii) Identification of compliance schedules and/or increments of 
progress;
    (iv) Demonstration that the State plan submittal is projected to 
achieve emissions performance under the applicable emission guidelines;
    (v) Documentation of state recordkeeping and reporting

[[Page 65060]]

requirements to determine the performance of the plan as a whole; and
    (vi) Demonstration that each emission standard is quantifiable, 
non-duplicative, permanent, verifiable, and enforceable.
    (4) Parallel processing. A State may submit a State plan prior to 
actual adoption by the State in order to expedite review and provide an 
opportunity for the State to consider EPA comments prior to submission 
of a final plan for final review and action. Under these circumstances, 
the following exceptions to the criteria in this paragraph apply to 
plans submitted explicitly for parallel processing:
    (i) The letter required by paragraph (g)(2)(i) of this section must 
request that EPA propose approval of the proposed plan by parallel 
processing;
    (ii) In lieu of paragraph (g)(2)(ii) of this section the State must 
submit a schedule for final adoption or issuance of the plan;
    (iii) In lieu of paragraph (g)(2)(iv) of this section the plan must 
include a copy of the proposed/draft regulation or document, including 
indication of the proposed changes to be made to the existing approved 
plan, where applicable; and
    (iv) The requirements of paragraphs (g)(2)(v) through (ix) of this 
section do not apply to plans submitted for parallel processing. The 
exceptions granted in the preceding sentence apply only to EPA's 
determination of proposed action and all requirements of paragraph 
(g)(2) of this section must be met prior to publication of EPA's final 
determination of plan approvability.
    (h) Full and partial approval and disapproval. If a portion of the 
plan revision meets all the applicable requirements of this chapter, 
the Administrator may approve the plan revision in part and disapprove 
the plan revision in part. The Administrator may authorize partial plan 
submissions in conjunction with a federal plan, where in combination, 
the federal and State plans constitute a complete and approvable plan 
meeting all of the requirements of this subpart and the applicable 
emissions guidelines.
    (i) Conditional approval. The Administrator may approve a plan or a 
plan revision based on a commitment of the State, by a date certain 
established by the Administrator, to adopt specific enforceable 
measures, review and revise if appropriate State plans, or otherwise 
commit to making changes in the State's plan necessary to meet the 
requirements of the applicable emission guidelines. Any such 
conditional approval automatically converts to a disapproval if the 
State fails to comply with such commitment by the date certain 
established by the Administrator.
    (j) Calls for plan revisions. Whenever the Administrator finds that 
the applicable plan is substantially inadequate to meet the 
requirements of the applicable emission guidelines, to provide for the 
implementation of such plan, or to otherwise comply with any 
requirement of the Clean Air Act, the Administrator must require the 
State to revise the plan as necessary to correct such inadequacies. The 
Administrator must notify the State of the inadequacies, and may 
establish reasonable deadlines (not to exceed 18 months after the date 
of such notice) for the submission of such plan revisions. Such 
findings and notice must be public. Any finding under this paragraph 
shall, to the extent the Administrator deems appropriate, subject the 
State to the requirements of this part to which the State was subject 
when it developed and submitted the plan for which such finding was 
made, except that the Administrator may adjust any dates applicable 
under such requirements as appropriate.
    (k) Error corrections. Whenever the Administrator determines that 
the Administrator's action approving, disapproving, or promulgating any 
plan or plan revision (or portion thereof) was in error, the 
Administrator may in the same manner as the approval, disapproval, or 
promulgation revise such action as appropriate without requiring any 
further submission from the State. Such determination and the basis 
thereof shall be provided to the State and public.

    (a) This subpart sets forth the requirements for the Clean Power 
Plan (CPP) CO2 Mass-based Trading Program, under section 111 
of the Clean Air Act and subpart UUUU of part 60 of this chapter, as a 
means of meeting emission guidelines limiting greenhouse gas emissions 
from an affected steam generating unit, integrated gasification 
combined cycle (IGCC), or stationary combustion turbine.
    (b) The pollutants regulated by this subpart are greenhouse gases. 
The greenhouse gas limitations in this subpart are in the form of an 
emission standard for carbon dioxide (CO2).
    (c) PSD and title V thresholds for greenhouse gases. (1) For the 
purposes of Sec.  51.166(b)(49)(ii) of this chapter, with respect to 
GHG emissions from affected facilities, the ``pollutant that is subject 
to the standard promulgated under section 111 of the Act'' is 
considered to be the pollutant that otherwise is subject to regulation 
under the Act as defined in Sec.  51.166(b)(48) and in any state 
implementation plan approved by the EPA that is interpreted to 
incorporate, or specifically incorporates, Sec.  51.166(b)(48) of this 
chapter.
    (2) For the purposes of Sec.  52.21(b)(50)(ii) of this chapter, 
with respect to GHG emissions from affected facilities, the ``pollutant 
that is subject to the standard promulgated under section 111 of the 
Act'' is considered to be the pollutant that otherwise is subject to 
regulation under the Act as defined in Sec.  52.21(b)(49) of this 
chapter.
    (3) For the purposes of Sec.  70.2 of this chapter, with respect to 
greenhouse gas emissions from affected facilities, the ``pollutant that 
is subject to any standard promulgated under section 111 of the Act'' 
is considered to be the pollutant that otherwise is ``subject to 
regulation'' as defined in Sec.  70.2 of this chapter.
    (4) For the purposes of Sec.  71.2 of this chapter, with respect to 
greenhouse gas emissions from affected facilities, the ``pollutant that 
is subject to any standard promulgated under section 111 of the Act'' 
is considered to be the pollutant that otherwise is ``subject to 
regulation'' as defined in Sec.  71.2 of this chapter.

Applicability of this Subpart


Sec.  62.16210  Am I subject to this subpart?

    (a) You are subject to this subpart if you are the owner or 
operator of an affected electric generating unit (EGU) located within a 
State that has incorporated by reference this subpart as a State plan, 
or portion of a State plan, that has been approved by the Administrator 
and is effective under subpart UUUU of part 60 of this chapter, or if 
this subpart is promulgated and effective as a federal plan in your 
State under part 62 of this chapter.
    (b) An affected EGU is any steam generating unit, IGCC, or 
stationary combustion turbine that meets the applicability requirements 
in Sec. Sec.  60.5840(b) and 60.5845 of this chapter.


Sec.  62.16215  What requirements apply to affected EGUs that retire?

    (a) Exemption. (1) Any affected EGU that is permanently retired as 
defined in Sec.  62.16375 is exempt from Sec. Sec.  62.16220(c)(1) 
[CO2 Emissions Requirements], 62.16340 [Compliance 
Requirements], 62.16345 [Monitoring], 62.16360 [Reporting], and 
62.16365 [Recordkeeping].
    (2) The exemption under paragraph (a)(1) of this section will 
become effective on the first day of the compliance period immediately 
following the compliance period in which the retirement took effect. 
Within 30 days of the affected EGU's permanent retirement, the 
designated representative must submit a statement to the Administrator. 
The statement must state, in a format prescribed by the Administrator, 
that the affected EGU was permanently retired on a specified date and 
will comply with the requirements of paragraph (b) of this section.
    (b) Special provisions. (1) An affected EGU exempt under paragraph 
(a) of this section must not emit any CO2, starting on the 
date that the exemption takes effect.
    (2) For a period of 5 years from the date the records are created, 
the owners and operators of an affected EGU exempt under paragraph (a) 
of this section must retain, at the facility that includes the unit, 
records demonstrating that the affected EGU is permanently retired. The 
5-year period for keeping records may be extended for cause, at any 
time before the end of the period, in writing by the Administrator. The 
owners and operators bear the burden of proof that the affected EGU is 
permanently retired.
    (3) The owners and operators and, to the extent applicable, the 
designated representative of an affected EGU exempt under paragraph (a) 
of this section must comply with the requirements of the CO2 
Mass-based Trading Program accruing during any compliance periods for 
which the exemption is not in effect, even if such requirements must be 
complied with after the exemption takes effect.

General Requirements


Sec.  62.16220  What requirements must I comply with?

    (a) Designated representative requirements. The owners and 
operators must have a designated representative, and may have an 
alternate designated representative, in accordance with Sec. Sec.  
62.16290 through 62.16300.
    (b) Emissions monitoring, reporting, and recordkeeping 
requirements. (1) The owners and operators, and the designated 
representative, of each facility and each affected EGU at the facility 
must comply with the monitoring, reporting, and recordkeeping 
requirements of Sec. Sec.  62.16345, 62.16360, and 62.16365.
    (2) The emissions data determined in accordance with Sec. Sec.  
62.16345, 62.16360, and 62.16365 must be used to calculate allocations 
of CO2 allowances under Sec.  62.16240(a) and (b) and to 
determine compliance with the CO2 emission standard under 
paragraph (c) of this section, provided that, for each monitoring 
location from which mass emissions are reported, the mass emissions 
amount used in calculating such allocations and determining such 
compliance must be the mass emissions amount for the monitoring 
location determined in accordance with

[[Page 65062]]

Sec.  62.16345 and rounded to the nearest ton.
    (c) CO2 emission standard requirements--(1) CO2 emission 
standard. (i) As of the allowance transfer deadline for a compliance 
period in a given year, the owners and operators of each facility and 
each affected EGU at the facility with affected EGUs must hold, in the 
facility's compliance account, CO2 allowances available for 
deduction for such compliance period under Sec.  62.16340(a) in an 
amount not less than the tons of total CO2 emissions for 
such compliance period from all affected EGUs at the facility.
    (ii) If total CO2 emissions during a compliance period 
in a given year from the affected EGUs at a facility are in excess of 
the CO2 emission standard set forth in paragraph (c)(1)(i) 
of this section, then:
    (A) The owners and operators of the facility and each affected EGU 
at the facility must hold the CO2 allowances required for 
deduction under Sec.  62.16340(d); and
    (B) The owners and operators of the facility and each affected EGU 
at the facility are subject to federal enforcement pursuant to sections 
113(a) through (h), and section 304, of the Clean Air Act, and the 
United States, States, and other persons have the ability to enforce 
against violations (including if an affected EGU does not meet its 
emission standard based on its allowances) and secure appropriate 
corrective actions, and must pay any fine, penalty, or assessment or 
comply with any other remedy imposed, for the same violations, under 
the Clean Air Act, and each ton of such excess emissions and each day 
of such compliance period will constitute a separate violation of this 
subpart and the Clean Air Act.
    (2) Compliance periods. (i) An affected EGU will be subject to the 
requirements under paragraph (c)(1) of this section for the compliance 
period starting on January 1, 2022 and for each compliance period 
thereafter.
    (ii) [Reserved]
    (3) Vintage of allowances held for compliance. (i) A CO2 
allowance held for compliance with the requirements under paragraph 
(c)(1)(i) of this section for a compliance period must be a 
CO2 allowance that was allocated for a year in such 
compliance period or for a year in a prior compliance period.
    (ii) A CO2 allowance held for compliance with the 
requirements under paragraph (c)(1)(ii)(A) of this section for a 
compliance period must be a CO2 allowance that was allocated 
for a year in a prior compliance period, or the current compliance 
period, or in the immediately following compliance period.
    (4) Allowance Tracking and Compliance System (ATCS) requirements. 
Each CO2 allowance must be held in, deducted from, or 
transferred into, out of, or between ATCS accounts in accordance with 
this subpart.
    (5) Limited authorization. A CO2 allowance is a limited 
authorization to emit one ton of CO2 during the compliance 
period in one year. Such authorization is limited in its use and 
duration as follows:
    (i) Such authorization must only be used in accordance with the 
CO2 Mass-based Trading Program; and
    (ii) Notwithstanding any other provision of this subpart, the 
Administrator has the authority to terminate or limit the use and 
duration of such authorization to the extent the Administrator 
determines is necessary or appropriate to implement any provision of 
the Clean Air Act.
    (6) Property right. A CO2 allowance does not constitute 
a property right.
    (d) Title V permit requirements. (1) Unless otherwise specified in 
this paragraph, all requirements of this subpart are applicable 
requirements that must be included in an affected EGU's title V permit.
    (2) The applicable requirements of this subpart, as well as other 
terms or conditions necessary to ensure compliance with the applicable 
requirements, may be added to, or changed in, a title V permit using 
minor permit modification procedures in accordance with Sec. Sec.  
70.7(e)(2) and 71.7(e)(1) of this chapter, provided that such changes 
do not conflict with any existing terms of the permit. This paragraph 
explicitly provides that the addition of, or change to, an affected 
EGU's description as described in the prior sentence is eligible for 
minor permit modification procedures in accordance with Sec. Sec.  
70.7(e)(2)(i)(B) and 71.7(e)(1)(i)(B) of this chapter.
    (3) No title V permit revision will be required for any allocation, 
holding, deduction, or transfer of CO2 allowances in 
accordance with this subpart, provided that the requirements applicable 
to such allocations, holdings, deductions, or transfers of 
CO2 allowances are already incorporated in such permit.
    (e) Liability. (1) Any provision of the CO2 Mass-based 
Trading Program that applies to an affected EGU at a facility or the 
designated representative of affected EGUs at a facility will also 
apply to the owners and operators of such facility and of the affected 
EGUs at the facility.
    (2) Any provision of the CO2 Mass-based Trading Program 
that applies to an affected EGU or the designated representative of an 
affected EGU will also apply to the owners and operators of such 
affected EGU.
    (f) Effect on other authorities. No provision of the CO2 
Mass-based Trading Program or exemption under Sec.  62.16215 shall be 
construed as exempting or excluding the owners and operators, and the 
designated representative, of an affected EGU from compliance with any 
other provision of the applicable, approved state implementation plan, 
a federally enforceable permit, or any other requirement of the Clean 
Air Act.


Sec.  62.16225  How should I compute time under the CO2 
Mass-based Trading Program?

    (a) Unless otherwise stated, any time period scheduled, under the 
CO2 Mass-Based Trading Program, to begin on the occurrence 
of an act or event will begin on the day the act or event occurs.
    (b) Unless otherwise stated, any time period scheduled, under the 
CO2 Mass-Based Trading Program, to begin before the 
occurrence of an act or event will be computed so that the period ends 
the day before the act or event occurs.
    (c) Unless otherwise stated, if the final day of any time period, 
under the CO2 Mass-Based Trading Program, is not a business 
day, then the time period will be extended to the next business day.


Sec.  62.16230  What are the administrative appeal procedures?

    The administrative appeal procedures for decisions of the 
Administrator under the CO2 Mass-Based Trading Program are 
set forth in part 78 of this chapter.


Sec.  62.16231  How will the Clean Energy Incentive Program be 
administered under the federal plan?

    (a)(1) The Administrator will participate in the Clean Energy 
Incentive Program, established under subpart UUUU of part 60 of this 
chapter, on behalf of any state for which this subpart is promulgated 
as a federal plan under section 111(d) of the Clean Air Act. The 
Administrator will award, on behalf of each such state, early action 
allowances for generation and savings achieved in 2020 and/or 2021 that 
result from the following types of eligible renewable energy (RE) and 
demand-side energy efficiency (EE) projects:
    (i) Metered wind power;
    (ii) Metered solar power; and
    (iii) Demand-side EE implemented in a low-income community.
    (2) Eligible RE projects must commence construction, and eligible 
demand-side EE projects must

[[Page 65063]]

commence implementation after September 6, 2018 for those states on 
whose behalf the EPA is implementing the federal plan. Eligible 
projects must be located in or benefit the state on whose behalf the 
EPA is implementing the federal plan.
    (b) Early action allowances will be distributed pursuant to a 
process to be prescribed by the Administrator, from an allowance set-
aside equal to 300 million allowances for all states. This set-aside 
does not increase the total budget of allowances for the affected EGUs 
in the state subject to this subpart.
    (c) The Administrator will match these early action allowances with 
additional matching allowances pursuant to a process to be prescribed 
by the Administrator. Matching awards will be made up to a limit 
equivalent to the state's pro rata share of 300 million short tons of 
CO2 emissions.
    (d) The awards, including the matching award, will be executed as 
follows:
    (1) For RE projects that generate metered MWh from wind or solar 
resources: for every two MWh generated, the project will receive a 
number of early action allowances the Administrator determines to be 
equivalent to one MWh from the set-aside under paragraph (b) of this 
section and a number of matching allowances the Administrator 
determines to be equivalent to one MWh from the match under paragraph 
(c) of this section.
    (2) For EE projects implemented in low-income communities as 
determined by the Administrator solely for purposes of this subpart: 
for every two MWh in end-use demand savings achieved, the project will 
receive a number of early action allowances the Administrator 
determines to be equivalent to two MWh from the set-aside under 
paragraph (b) of this section and a number of matching allowances the 
Administrator determines to be equivalent to two MWh from the match 
under paragraph (c) of this section.

Emission Goals, Set-Asides, and Allowance Allocations


Sec.  62.16235  What are the statewide mass-based emission goals, 
renewable energy set-asides, output-based set-asides, and Clean Energy 
Incentive Program early action set-asides?

    (a) The statewide mass-based emission goals with renewable energy 
set-asides and output-based set-asides for allocations of 
CO2 allowances for the interim 3- and 2-year compliance 
periods in 2022 through 2029, and the final 2-year compliance periods 
in 2030 and thereafter are specified in Table 1 of this subpart.

\1\ The values in this table are annual amounts; the mass goal for each multi-year compliance period is the annual value multiplied by the number of
  years in the compliance period. Each emission goal includes the renewable energy set-asides and output-based set-asides (the output-based set-asides
  are zero in the first compliance period). The first compliance period goals also include the early action Clean Energy Incentive Program set-aside.

    (b) If implementing interstate trading, then the Administrator will 
use the sum of a covered group of States' mass-based emission goals as 
the aggregate mass-based emission goal.
    (c) The renewable energy set-aside for each State covered by the 
federal mass-based emissions trading plan must reserve 5 percent from 
the State's annual allowances prior to allocation of that year's 
allowances to facilities. The renewable energy set-asides are specified 
in Table 2 of this subpart.

    (2) Allowances may be distributed from the set-aside for projects 
meeting the criteria of paragraph (e)(3) of this section, upon 
application of a project proponent that meets the requirements of Sec.  
62.16245(a), except as may be prescribed by the Administrator in a 
future action. In order to receive a distribution, the project 
proponent must establish a general account in the tracking system as 
provided in Sec.  62.16320(c).
    (3) Projects eligible for distribution of allowances from this set-
aside must meet each of the criteria in paragraphs (e)(3)(i) through 
(iii) of this section. All categories of resources other than those 
listed in paragraphs (e)(3)(iii)(A) and (B) of this section, and all 
provisions of this subpart relating to such resources, are not 
available or applicable in States where this subpart has been 
promulgated as a federal plan pursuant to section 111(d)(2) of the 
Clean Air Act.
    (i) The project was constructed or implemented on or after the 
signature date of the final rule promulgating subpart UUUU of part 60 
of this chapter;
    (ii) The creditable generation or energy savings from the project 
must occur in calendar years 2020 or 2021; and
    (iii) Generation or energy savings must be from one of the 
following types of sources capable of revenue-quality metering:
    (A) Onshore wind;
    (B) Solar; or
    (C) Demand-side EE.


Sec.  62.16240  When are allowances allocated?

    (a) Allowance allocations. (1) By June 1, 2021, and by June 1 of 
each year prior to the beginning of each compliance period thereafter, 
CO2 allowances will be allocated, for the multi-year 
compliance periods in the Interim Period beginning in 2022 and the 
Final Period beginning in 2030, as provided by the Administrator in a 
notice of data availability or through this subpart (if applicable). 
Providing an allocation to an entity does not constitute as an 
applicability determination of an affected EGU.
    (2) Notwithstanding paragraph (a)(1) of this section, if an 
affected EGU which is provided an allocation does not operate for 2 
consecutive calendar years, then such affected EGU will not be 
allocated the CO2 allowances provided by the Administrator 
in a notice of data availability or through this subpart (if 
applicable) for the affected EGU for the next compliance period for 
which allowances have not yet been recorded and for each compliance 
period after that compliance period. All CO2 allowances that 
would otherwise have been allocated to such affected EGU will be 
allocated to the renewable energy set-aside for the State where such 
affected EGU is located and for the respective compliance periods 
involved.
    (3) Notwithstanding paragraph (a)(1) of this section, if an 
affected EGU provided an allocation issued by the Administrator in 
notice of data availability or through this subpart (if applicable) is 
modified or reconstructed such that it is no longer subject to this 
subpart, then such affected EGU will not be allocated the 
CO2 allowances provided for the affected EGU for the next 
compliance period for which allowances have not yet been recorded and 
for each compliance period after that compliance period. All 
CO2 allowances that would otherwise have been allocated to 
such affected EGU will be allocated to the renewable energy set-aside 
for the State where such affected EGU is located and for the respective 
compliance periods involved.
    (b) Set-asides--(1) Renewable energy set-asides. (i) By December 1, 
2021 and December 1 of each year thereafter, the Administrator will 
calculate and allocate the CO2 allowance allocation to each 
approved renewal energy project in a State, in accordance with Sec.  
62.16245(a)(2) through (5), for the generation year of the applicable 
calculation deadline under this paragraph.
    (ii) By December 1, 2021 and December 1 of each year thereafter, 
the Administrator will calculate and allocate the CO2 
allowance allocation to each affected EGU in a State, in accordance 
with Sec.  62.16245(a)(6) and (7) for the generation year of the 
applicable calculation, and will promulgate a notice of data 
availability of the results of the calculations.
    (2) Output-based set-asides. (i) By November 1 of the first year of 
each compliance period beginning in 2025, and each compliance period 
thereafter, the Administrator will calculate and allocate the 
CO2 allowance allocation to each affected EGU in a State, in 
accordance with Sec.  62.16245(b)(3), for the generation period of the 
applicable calculation deadline under this paragraph.
    (ii) By November 1 of the first year of each compliance period 
beginning in 2025, and each compliance period thereafter, the 
Administrator will calculate and allocate the CO2 allowance 
allocation to each affected EGU in a State, in accordance with Sec.  
62.16245(b)(4) and (5) for the generation period of the applicable 
calculation, and will promulgate a notice of data availability of the 
results of the calculations.
    (c) Affected EGUs incorrectly allocated CO2 allowances. 
(1) For each compliance period in 2022 and thereafter, if the 
Administrator determines that CO2 allowances were allocated 
under paragraph (a) of this section, or under a provision of a state 
allowance distribution methodology approved under subpart UUUU of part 
60 of this chapter, where such compliance period and the recipient are 
covered by the provisions of paragraph (c)(1)(i) of this section or 
were allocated under Sec.  62.16245(a) and (b), where such compliance 
period and the recipient are covered by the provisions of paragraph 
(c)(1)(ii) of this section, then the Administrator will notify the 
designated representative of the recipient and will act in accordance 
with the procedures set forth in paragraphs (c)(2) through (5) of this 
section. The situations for the Administrator to act according to the 
procedures in paragraphs (c)(2) through (5) are if:
    (i)(A) The recipient is not actually an affected EGU under Sec.  
62.16210 as of January 1, 2022 and is allocated CO2 
allowances for such compliance period or, in the case of an allocation 
under a provision of a state allowance distribution methodology 
approved under subpart UUUU of part 60 of this chapter, the recipient 
is not actually an affected EGU as of January 1, 2022 and is allocated 
CO2 allowances for such compliance period that the state 
allowance distribution methodology provides should be allocated only to 
recipients that are affected EGUs as of January 1, 2022; or
    (B) The recipient is not located as of January 1 of the compliance 
period in the State from whose CO2 allowances the 
CO2 allowances allocated under paragraph (a) of this 
section, or under a provision of a state allowance distribution 
methodology approved under subpart UUUU of part 60 of this chapter, 
were allocated for such compliance period.
    (ii) The recipient is not actually an affected EGU under Sec.  
62.16210 as of January 1 of such compliance period and is allocated 
CO2 allowances for such compliance period or, in the case of 
an allocation under a provision of a state allowance distribution 
methodology approved under subpart UUUU of part 60 of this chapter, the 
recipient is not actually an affected EGU as of January 1 of such 
compliance period and is allocated CO2 allowances for such 
compliance period that the state allowance distribution methodology 
provides should be allocated only to recipients that are

[[Page 65068]]

affected EGUs as of January 1 of such compliance period.
    (2) Except as provided in paragraph (c)(3) or (4) of this section, 
the Administrator will not record such CO2 allowances under 
Sec.  62.16325.
    (3) If the Administrator already recorded such CO2 
allowances under Sec.  62.16325 and if the Administrator makes the 
determination under paragraph (c)(1) of this section before making 
deductions for the facility that includes such recipient under Sec.  
62.16340(b) for such compliance period, then the Administrator will 
deduct from the account in which such CO2 allowances were 
recorded an amount of CO2 allowances allocated for the same 
or a prior compliance period equal to the amount of such already-
recorded CO2 allowances. The authorized account 
representative must ensure that there are sufficient CO2 
allowances in such account for completion of the deduction.
    (4) If the Administrator already recorded such CO2 
allowances under Sec.  62.16325 and if the Administrator makes the 
determination under paragraph (c)(1) of this section after making 
deductions for the facility that includes such recipient under Sec.  
62.16340(b) for such compliance period, then the Administrator will not 
make any deduction to take account of such already-recorded 
CO2 allowances.
    (5)(i) With regard to the CO2 allowances that are not 
recorded, or that are deducted as an incorrect allocation, in 
accordance with paragraphs (c)(2) and (3) of this section for a 
recipient under paragraph (c)(1)(i) of this section, the Administrator 
will:
    (A) Transfer such CO2 allowances to the renewable energy 
set-aside for such compliance period for the State from whose 
CO2 allowances the CO2 allowances were allocated; 
or
    (B) If the State has a state allowance distribution methodology 
approved under subpart UUUU of part 60 of this chapter covering such 
compliance period, then include such CO2 allowances in the 
portion of the CO2 allowances that may be allocated for such 
compliance period in accordance with such state allowance distribution 
methodology.
    (ii) With regard to the CO2 allowances that were not 
allocated from a renewable energy or output-based set-aside for such 
compliance period and that are not recorded, or that are deducted as an 
incorrect allocation, in accordance with paragraphs (c)(2) and (3) of 
this section for a recipient under paragraph (c)(1)(ii) of this 
section, the Administrator will:
    (A) Transfer such CO2 allowances to the renewable energy 
set-aside for such compliance period; or
    (B) If the State has a state allowance distribution methodology 
approved under subpart UUUU of part 60 of this chapter covering such 
compliance period, then include such CO2 allowances in the 
portion of the CO2 allowances that may be allocated for such 
compliance period in accordance with such state allowance distribution 
methodology.
    (iii) With regard to the CO2 allowances that were 
allocated from the renewable energy or output-based set-aside for such 
compliance period and that are not recorded, or that are deducted as an 
incorrect allocation, in accordance with paragraphs (c)(2) and (3) of 
this section for a recipient under paragraph (c)(1)(ii) of this 
section, the Administrator will transfer such CO2 allowances 
back to the renewable energy set-aside, or to the output-based set-
aside, respectively, for such compliance period.


Sec.  62.16245  How are set-aside allowances allocated?

    (a)(1) Renewable energy set-aside. The Administrator will establish 
a renewable energy set-aside as set forth in Sec.  62.16235(c), and 
allocate CO2 allowances from the set-aside for each year of 
a compliance period as outlined in this section.
    (2) Eligible renewable energy capacity. To be eligible to receive 
renewable energy set-aside allowances, an eligible resource must meet 
each of the requirements in paragraphs (a)(2)(i) through (v) of this 
section. Any resource that does not meet the requirements of paragraphs 
(a)(2)(i) through (v) of this section cannot receive set-aside 
allowances.
    (i) The resource must be a renewable energy resource that falls 
into one of the following categories of resources: on-shore utility 
scale wind, solar, geothermal power, or utility scale hydropower.
    (ii) The resources must only include resources which increased new 
installed electrical generation nameplate capacity, or new electrical 
savings measures installed or implemented after January 1, 2013. If a 
resource had a nameplate capacity uprate, then set-aside allowances may 
be issued only for the difference in generation between the uprated 
nameplate capacity and its nameplate capacity prior to the uprate. Set-
aside allowances must not be issued for generation for an uprate that 
followed a derate that occurred on or after January 1, 2013. A resource 
that is relicensed or receives a license extension is considered 
existing capacity and is not an eligible resource, unless it receives a 
capacity uprate as a result of the relicensing process that is 
reflected in its relicensed permit. In such a case, only the difference 
in nameplate capacity between its relicensed permit and its prior 
permit is eligible to be issued set-aside allowances.
    (iii) The resource must be located in the mass-based State for 
which the set-aside has been designated.
    (iv) The resource must be connected to, and delivers energy to or 
saves electricity, on the electric grid in the contiguous United 
States.
    (v) The resource must not have received emission rate credits 
(ERCs) for any period of time for which it receives set-aside 
allowances.
    (3) Process for issuance of set-aside allowances. The process and 
requirements for issuance of set-aside allowances are set forth in 
paragraphs (a)(3)(i) through (x) of this section.
    (i) Eligibility application. To receive set-aside allowances, an 
authorized account representative of an eligible resource must submit 
an eligibility application to the Administrator that demonstrates that 
the requirements of paragraph (a)(2) of this section are met and 
demonstrates that the following requirements are met:
    (A) Identification of the authorized account representative of the 
eligible resource, including the authorized account representative's 
name, address, email address, telephone number, and allowance tracking 
system account number; and
    (B) Identification of the eligible resource(s), including the 
physical location of the eligible resource; contact information for the 
owner or operator of the eligible resource, if different from the 
authorized account representative and designated representative; 
generator prime mover and technology type; generator nameplate capacity 
(if applicable); generator category (e.g., wholesale generator, 
wholesale generator also serving onsite customer load, customer-sited 
distributed generator) (if applicable); facility and generating unit 
IDs (EIA ORIS Code, Facility Registration System (FRS) Code, if 
applicable) (if applicable); the control area, balancing authority, ISO 
conditions as defined in Sec.  62.16375 (if applicable), or regional 
transmission organization in which the generator is located (if 
applicable); and a copy of the most recent filing of a copy of the 
generating facility's U.S. Energy Information Agency's Annual Electric 
Generator Report Form EIA-860 (if applicable).

[[Page 65069]]

    (ii) Renewable energy providers must open a general account per the 
requirements in Sec.  62.16320(c), and submit a project application for 
renewable energy set-aside allowances to the Administrator by June 1 of 
the year prior to the generation year for which set-aside allowances 
are requested. Providers may update submitted projections for future 
generation years, these projections must be received by June 1 of the 
year prior to the generation year in question. The project application 
must contain the following information:
    (A) Projection of the project's annual renewable energy generation 
in MWh.
    (B) Documentation of the methodology, data facilities, and 
assumptions used to project the project's annual renewable energy 
generation.
    (C) A certification that the eligibility application has only been 
submitted to the Administrator or pursuant to an EPA-approved multi-
State approach where States are providing for joint issuance of 
allowances pursuant to the authority in their individual State plans.
    (D) A evaluation, measurement, and verification (EM&V) plan.
    (E) A verification report from an accredited independent verifier 
who meets the requirements of Sec.  62.16275 and Sec.  62.16280. While 
considered a part of the eligibility application, the verification 
report must be submitted separately by the accredited independent 
verifier to the Administrator.
    (F) An authorization that provides for the following: the 
Administrator may inspect (including a physical inspection of the 
eligible resource and its meter) and/or audit the eligible resource at 
any time and verify that the eligible resource and the EM&V plan have 
been implemented as described in the eligibility application.
    (G) The following statement, signed by the authorized account 
representative of the eligible resource:
    (1) ``I certify under penalty of law that I have personally 
examined, and am familiar with, the statements and information 
submitted in this document and all its attachments. Based on my 
personal knowledge and/or inquiry of those individuals with primary 
responsibility for obtaining the information, I certify that the 
statements and information are to the best of my knowledge and belief 
true, accurate, and complete. I am aware that there are significant 
penalties for submitting false statements and information or omitting 
required statements and information, including the possibility of fine 
or imprisonment.''
    (2) [Reserved]
    (H) Any other information required by the Administrator.
    (4) Monitoring and verification. After the generation year for 
which a provider received set-aside allowances for an eligible 
resource, the authorized account representative must submit to the 
Administrator:
    (i) A measurement and verification (M&V) report.
    (ii) A verification report from an accredited independent verifier 
that meets the requirements of Sec.  62.16275 and Sec.  62.16280. While 
considered a part of the M&V report, the verification report must be 
submitted separately by the accredited independent verifier to the 
Administrator.
    (5) Allocation of renewable energy set-aside allowances. The 
Administrator will enter the projected generation from each approved 
project into a pool of projects for that State that will receive set-
asides for a generation year.
    (i) The Administrator will distribute renewable energy set-aside 
allowances for a generation year with the number of allowances 
distributed to each project prorated according to its percentage of the 
total approved projected MWhs for that State that the project 
represents.
    (ii) If in the previous generation year, the project did not reach 
the MWhs projected, then the unfulfilled MWhs will be subtracted from 
that provider's projected generation eligible for the set-aside pool.
    (iii) If the unfulfilled MWhs from a previous year exceed the 
projected hours for the generation year, then the Administrator will 
carry over the deficit and subtract from the projected generation in 
subsequent years until there is no deficit. If this deficit is greater 
than 10 percent in a particular year, then the provider will need to 
provide an explanation to the Administrator of the deficit, and will be 
required to reevaluate their projections for future years. If such 
deficits continue through all 3 years of the first or second compliance 
period, then the Administrator will disqualify the provider from 
receiving future set-asides for the following compliance period.
    (6) Surplus renewable set-aside allowances. If, after completion of 
the procedures under paragraph (a)(5) of this section for each 
compliance period, any unallocated CO2 allowances remain in 
the renewable energy set-aside for the State for such generation year, 
the Administrator will allocate the amount of CO2 allowances 
in a pro rata fashion on the same distribution basis as their initial 
allocations were made to each affected EGU that: is in the State; is 
allocated an amount of CO2 allowances in the notice of data 
availability issued under Sec.  62.16240(a)(1); and continues to be 
allocated CO2 allowances for such compliance period in 
accordance with Sec.  62.16240(a)(2).
    (7) Notice of surplus renewable energy set-aside allowance 
distribution. The Administrator will make public the amount of 
CO2 allowances allocated under paragraph (a)(6) of this 
section for such generation year period to each affected EGU eligible 
for such allocation.
    (b)(1) Output-based set-aside. The Administrator will establish an 
output-based set-aside beginning in compliance period 2, and allocate 
CO2 allowances from the set-aside for each year of a 
compliance period as set forth in Sec.  62.16235(c).
    (2) Unit eligibility. To be eligible to receive output-based set-
aside allowances, affected EGUs must meet the following eligibility 
requirements:
    (i) The affected EGU must be a natural gas combined cycle unit;
    (ii) The affected EGU must be located in the mass-based State for 
which the set-aside has been designated; and
    (iii) The affected EGU's average capacity factor in the preceding 
compliance period was above 50 percent based on net summer capacity and 
net generation.
    (3) Allocation of output-based set-aside allowances. The 
Administrator will allocate output based set-aside allowances for each 
eligible EGU based on its average net generation and net summer 
capacity in the preceding compliance period.
    (i) The Administrator will calculate the amount of allowances an 
eligible EGU receives from the output-based set-aside as the unit's 
average net generation in the preceding compliance period over 50 
percent multiplied by the allocation rate of 1,030 lb/MWh-net.
    (ii) If the amount of total allowances exceeds the size of the 
State's set-aside, then the allowances will be allocated to the State's 
eligible generation on a pro-rata basis.
    (iii) The Administrator will provide notice of the net summer 
capacity and net generation data used, and the resulting allocations by 
August 1 of the first year of each compliance period beginning in 2025. 
The notice of the net summer capacity and net generation data used, and 
the resulting allocations, must allow 30 days for public comment on the 
data and allocations, until August 31 of the same year.
    (iv) The Administrator will provide notice of the final set-aside 
allocations by November 1 of the same year.
    (4) Surplus output-based set-aside allowances. If, after completion 
of the

[[Page 65070]]

procedures under paragraph (b)(3) of this section for each compliance 
period, any unallocated CO2 allowances remain in the out-put 
based set-aside for the State for such generation period, the 
Administrator will allocate the amount of CO2 allowances in 
a pro rata fashion on the same distribution basis as their initial 
allocations were made to each affected EGU that: is in the State; is 
allocated an amount of CO2 allowances in the notice of data 
availability issued under Sec.  62.16240(a)(1); and continues to be 
allocated CO2 allowances for such compliance period in 
accordance with Sec.  62.16240(a)(2).
    (5) Notice of surplus output-based set-aside. The Administrator 
will notify the public, through the promulgation of the notices of data 
availability described in Sec.  62.16240(b)(1) and (2), of the amount 
of CO2 allowances allocated under paragraphs (b)(3) and (4) 
of this section for such compliance period to each affected EGU 
eligible for such allocation.


Sec.  62.16250  What is the process for revocation of qualification 
status of an eligible resource?

    (a) If an eligible resource is found to not meet the requirements 
of Sec.  62.16260 in the CO2 Mass-based Trading Program, 
then the Administrator will revoke the eligibility of the eligible 
resource to be issued set-aside allowances. In addition, the provisions 
of Sec.  62.16255(d) may apply.
    (b) Any instance of intentional misrepresentation in an eligibility 
application or M&V report may be cause for revocation of the 
qualification status of an eligible resource.
    (c) Repeated instances of error or misstatement of MWh of 
electricity generation or savings in submitted M&V reports, or in any 
other submissions may be cause for the Administrator to revoke the 
eligibility of an eligible resource to be issued set-aside allowances.
    (d) In the event of an intentional misrepresentation, or repeated 
instances of error or misstatement, in program submissions, by the 
authorized account representative of the eligible resource, the 
Administrator may prohibit the eligible resource from any further 
eligibility to be issued allowances. In addition, the provisions of 
Sec.  62.16255(a) through (d) may apply.


Sec.  62.16255  What is the process for error adjustments or 
misstatement, and suspension of allowance issuance?

    (a) In the event of error or misstatement of quantified MWh of 
electricity generation or savings in a previous M&V report for which 
set-aside allowances have been issued, the Administrator may adjust the 
number of set-aside allowances issued in a subsequent reporting period 
to address the error or misstatement, by subtracting a number of MWh 
from the quantified and verified MWh in the M&V report for the 
subsequent reporting period. In the event that an error or inadvertent 
misstatement occurs in a final M&V report for an eligible resource, for 
which set-aside allowances have been issued, the provisions of 
paragraph (b) of this section will apply.
    (b) In the event of error or misstatement of quantified MWh of 
electricity generation or savings in the final M&V report for an 
eligible resource, for which set-aside allowances have been issued, the 
Administrator will revoke set-aside allowances from the general account 
held by the authorized account representative of the eligible resource, 
in an amount necessary to correct the error or misstatement. In the 
event that the general account of the eligible resource holds an 
insufficient number of set-aside allowances to correct the error or 
misstatement, the authorized account representative must submit to the 
Administrator within 30 days a number of set-aside allowances necessary 
to correct the error or misstatement. Failure to meet this requirement 
will result in prohibition of the authorized account representative for 
the eligible resource from further participation in the program, unless 
reauthorized at the discretion of the Administrator.
    (c) The Administrator may freeze the general account held by an 
authorized account representative of an eligible resource at any time, 
for cause, if the Administrator determines set-aside allowances have 
been improperly issued, based on a misrepresentation or misstatement in 
an eligibility application or M&V report. The Administrator may also 
freeze the general account of an authorized account representative of 
an eligible resource pending investigation of potential 
misrepresentation, error, or misstatement in an eligibility application 
of an eligible resource, or in an M&V report for which set-aside 
allowances have been issued. Freezing a general account will prevent 
transfer of allowances out of the account.
    (d) If set-aside allowances are issued for an eligible resource 
that is found to be ineligible, then the Administrator may take the 
actions in paragraphs (d)(1) through (3) of this section.
    (1) Freeze the general account of the authorized account 
representative for an eligible resource, preventing any transfers of 
allowances out of the account.
    (2) Revoke or deduct allowances held in the general account of the 
authorized account representative for an eligible resource, in a number 
equal to the number of allowances issued for the ineligible eligible 
resource.
    (3) In the event that the general account of the eligible resource 
holds a number of allowances less than the number of set-aside 
allowances issued for the ineligible eligible resource, the delegated 
representative of an eligible resource must submit to the Administrator 
within 30 days a number of allowances necessary to fully account for 
all allowances issued for the ineligible eligible resource. Failure to 
meet this requirement will result in prohibition of the eligible 
resource from further participation in the program, unless reauthorized 
at the discretion of the Administrator.
    (e) The Administrator may temporarily or permanently suspend 
issuance of set-aside allowances for an eligible resource, for the 
following reasons in paragraphs (e)(1) through (3) of this section.
    (1) Pending investigation of potential misrepresentation, error, or 
misstatement in an M&V report, for which set-aside allowances have been 
issued, or the eligibility status of an eligible resource.
    (2) In the case of repeated error or misstatements in submitted M&V 
reports.
    (3) In the case of an intentional misrepresentation in a submitted 
M&V report.

Evaluation Measurement and Verification Plans, Monitoring and 
Verification Reports, and Verification


Sec.  62.16260  What are the requirements for evaluation, measurement 
and verification plans for eligible resources?

    (a) EM&V plan requirements. Any EM&V plan submitted in support of 
the issuance of a set-aside allowance pursuant to this rule must meet 
the requirements of this section.
    (b) General EM&V plan criteria. Each EM&V plan must identify the 
eligible resource and its approved eligibility application.
    (c) Specific EM&V plan criteria. Each EM&V plan must provide the 
manner in which the electricity generated or saved by the eligible 
resource will be quantified, monitored and verified, and the manner of 
quantification, monitoring and verification must meet the criteria 
listed in paragraphs (c)(1) through (7) of this section, as applicable 
to the specific eligible resource.

[[Page 65071]]

    (1) For a nuclear energy resource or a renewable energy resource 
with a nameplate capacity of 10 kW or more and for a renewable energy 
resource with a nameplate capacity of less than 10 kW for which metered 
data are available, each EM&V plan must specify that the requirements 
in paragraphs (c)(1)(i) through (vi) of this section must be met.
    (i) The generation data are physically measured on a continuous 
basis using a revenue-quality meter, which means a meter used by a 
control area operator for financial settlements, or a meter that meets 
the American National Standards Institute No. C12.20., Code for 
Electricity Metering, metering accuracy standards, or a meter that 
meets an alternative equivalent standard that has been approved in 
advance of its use to measure generation pursuant to this regulation by 
the EPA.
    (ii) The generating data are measured at the generator's bus bar, 
or, for a renewable energy resource with a nameplate capacity of less 
than 10 kW that is interconnected behind an individual business or 
household meter, the generating data were measured at the AC output of 
the inverter and adjusted to reflect the only energy delivered into 
either the transmission or distribution grid at the generator bus bar 
and not any energy used on-site at the generator.
    (iii) The generation data from only one eligible resource 
generating unit may be associated with each meter, and generation data 
may not be aggregated, unless all the following provisions are met:
    (A) All of the generating units have the same essential generation 
characteristics;
    (B) All of the generating units are located in the same State;
    (C) The nameplate capacity of the individual units being aggregated 
is each less than 150 kW, and units collectively do not exceed a total 
nameplate capacity of 1 MW when aggregated, or alternative requirements 
approved by the EPA in connection with the specific State plan pursuant 
to which that EM&V plan or M&V report is submitted; and
    (D) The generation data are measured by the same type of meter that 
is subject to the same maintenance and quality assurance procedures.
    (iv) The generation data are collected electronically and 
telemetered from the generator to its control area operator and 
verified through a control area energy accounting or settlement process 
which occurs at least monthly, unless the generation unit does not go 
through a control area operator, in which case the generation data must 
be collected by manual meter readings conducted by an independent 
verifier that is either not affiliated with the owner or operator of 
the qualifying renewable energy generating resource or is precluded 
pursuant to the relevant State plan from the ability to transfer or 
retire set-aside allowances issued to that qualifying renewable energy 
generating resource or, if the generating unit is less than 10 kw and 
does not generate enough electricity to enable monthly reporting, then 
the data may be self-reported and reported no less than annually.
    (v) The generation data serve a load that otherwise would have been 
served by the grid if not for the generator. Specifically:
    (A) Set-aside allowances shall not be issued for energy generation 
used to supply the ancillary equipment used to operate a generating 
station or substation (``station service'') or parasitic load on the 
generator's side of the point of interconnection; and
    (B) For generators interconnected to transmission systems and with 
on-site loads other than station service drawing generation before the 
metering point, set-aside allowances may be issued for on-site load, if 
the owner or operator of the eligible resource can demonstrate that the 
metering used is capable of distinguishing between on-site load and 
station service.
    (vi) Any other requirements approved by the EPA in connection with 
the specific State plan pursuant to which that EM&V plan is submitted.
    (2) For a renewable energy resource with a nameplate capacity of 
less than 10 kW and that does not have a meter, each EM&V plan must 
require that the following requirements in paragraphs (c)(2)(i) through 
(vii) of this section are met.
    (i) Metered data are unavailable.
    (ii) At least 1 MW of net energy output is generated to the 
distribution or transmission system over a continuous 365-day period.
    (iii) The generation data may not be aggregated, unless the 
following provisions are met:
    (A) All of the generating units have the same essential generation 
characteristics;
    (B) All of the generating units are located in the same State;
    (C) The nameplate capacity of the individual units being aggregated 
is each less than 150 kW, and units collectively do not exceed a total 
nameplate capacity of 1 MW when aggregated, or alternative requirements 
approved by the EPA in connection with the specific State plan pursuant 
to which that EM&V plan or M&V report is submitted; and
    (D) The generation data are measured by the same generation 
estimating software or algorithms.
    (iv) The generation data are measured on at least a monthly basis 
using generation estimating software or algorithms that are based on an 
on-site inspection prior to interconnection and a resource study (wind, 
shading, solar irradiance, depending on the resource), or engineering 
information that takes into account the capacity, age, and type of 
qualifying energy generating resource, and all input parameters and 
assumptions must be clearly delineated, or if the generating unit does 
not generate enough electricity to enable monthly reporting, then the 
data may be reported no less than annually.
    (v) The generation data are self-reported to the distribution 
utility through an electronic internet-based portal with software that 
reports total and hourly generation.
    (vi) The generation data serves a load that otherwise would have 
been served by the grid if not for the generator. The set-aside 
allowance is only based on generation transferred from the eligible 
resource to the transmission or distribution grid, and is not based on 
the generation used on-site by the customer.
    (vii) Any other requirements approved by the EPA in connection with 
the specific State plan pursuant to which that EM&V plan is submitted.
    (3) For qualified biomass feedstocks used, in addition to the 
requirements of paragraph (c)(1) or (2) of this section, whichever 
section is applicable, each EM&V plan must demonstrate that the 
requirements approved by the EPA for that biomass feedstock, and its 
associated biogenic CO2, have been met.
    (4) For a waste-to-energy resource, in addition to the requirements 
of paragraph (c)(1) or (2) of this section, as applicable, and 
paragraph (c)(3) of this section, each EM&V plan must specify:
    (i) The total net energy generation from the resource in MWh;
    (ii) The method for determining the specific portion of the total 
net energy output from the resource that is related to the biogenic 
portion of the waste; and
    (iii) The net energy output is measured with the relevant method 
approved by the EPA in connection with the specific State plan pursuant 
to which that EM&V plan is submitted demonstrates that the requirements 
approved by the EPA in connection with that State plan have been met.
    (5) For a combined heat and power unit, in addition to the 
requirements of paragraphs (c)(1) or (2) of this section,

[[Page 65072]]

as applicable, and paragraph (c)(3) of this section, each EM&V plan 
must meet one of the requirements in paragraphs (c)(5)(i) through (iv) 
of this section, as applicable, and any other requirements approved by 
the EPA.
    (i) If the combined heat and power unit has an electric generating 
capacity greater than 25 MW, then the EM&V plan must meet the 
requirements that apply to an affected EGU under Sec.  62.16540 of this 
subpart.
    (ii) If the combined heat and power unit has an electric generating 
capacity less than or equal to 25 MW and greater than 1 MW, and it uses 
only natural gas and/or distillate fuel oil, then the EM&V plan must 
meet the low mass emission unit CO2 emission monitoring and 
reporting methodology in part 75 of this chapter.
    (iii) If the combined heat and power unit has an electric 
generating capacity less than or equal to 25 MW and greater than 1 MW, 
and it uses anything other than only natural gas and/or distillate fuel 
oil, then the EM&V plan must meet the low mass emission unit 
CO2 emission monitoring and reporting methodology in part 75 
of this chapter.
    (iv) If the combined heat and power unit has an electric generating 
capacity less than or equal to 1 MW the unit must keep monthly 
cumulative recordings of useful thermal output and fossil fuel input 
along with the determination of baseline thermal source efficiencies 
based on manufacturer data. For CHP units that directly serve on-site 
end-use electricity loads, avoided transmission and distribution (T&D) 
system losses can be assessed as is commonly practiced with demand-side 
EE.
    (6) For electricity savings that avoid a transmission and 
distribution loss, each EM&V plan must measure the transmission and 
distribution loss based on the lesser of 6 percent of the site-level 
electricity savings measured at the end use meter or the statewide 
annual average transmission and distribution loss rate (expressed as a 
percentage) from the most recent year that is published in the US EIA 
State Electricity Profile expressed as a percentage. No other 
transmission and distribution loss factors may be used in calculating 
the electricity savings, including measures such as conservation 
voltage reduction and volt/VAR optimization.
    (7) Each EM&V plan for an EE program, EE project, or EE measure 
must specify how each of the requirements in paragraphs (c)(7)(i) 
through (x) of this section will be met in quantifying the electricity 
savings from that EE program, EE project, or EE measure.
    (i) All electricity savings must be quantified on an ex-post basis, 
which means after the electricity savings have occurred, or on a real-
time basis, which means at the time the electricity savings are 
occurring. Electricity savings must not be quantified on an ex-ante 
basis, which means estimates of MWh savings that are generated prior to 
implementing the subject EE program, EE project, or EE measure, and 
that are not quantified using EM&V methods and procedures.
    (ii) All electricity savings must be quantified and verified based 
on methods and procedures detailed in an industry best-practice EM&V 
protocol or guideline. Each EM&V plan must include a demonstration of 
how the best-practice protocol or guideline was selected and will be 
applied to the specific EE program, EE project, or EE measure covered 
in the EM&V plan, and an explanation of why that particular protocol or 
guideline was selected. Protocols and guidelines are considered to be 
best practice if they:
    (A) Have gone through a rigorous and credible peer review process 
that shows the applicable methods to be valid through empirical 
testing; and
    (B) Have been accepted and approved for use by identifiable state 
regulatory commissions. Examples of such protocols and guidelines that 
may be provided in EM&V guidance issued by the Administrator will be 
acceptable.
    (iii) All electricity savings must be quantified as the difference 
between the observed electricity use and a common practice baseline 
(CPB), which is the equipment that would typically have been 
installed--or that a typical consumer or building owner would have 
continued using--in a given circumstance (i.e., a given building type, 
EE program type or delivery mechanism, and geographic region) at the 
time of EE implementation. Examples of CPBs for specific EE programs, 
EE projects, EE measures, and for certain EM&V methods that may be 
provided in EM&V guidance issued by the Administrator will be 
acceptable. The EM&V plan must specify the reason the specific CPB was 
selected, which must include an analysis of the appropriateness of that 
CPB for the EE program, EE project, or EE measure covered in the EM&V 
plan, based on:
    (A) Characteristics of the EE program, EE project, or EE measure;
    (B) The delivery mechanism used to implement the EE program, EE 
project, or EE measure (e.g., installed as part of a utility EE program 
versus a point-of-sale rebate);
    (C) Local consumer and market characteristics;
    (D) Applicable building energy codes and standards and average 
compliance rates; and
    (E) The method applied: project-based measurement and verification 
(PB-MV), comparison group approaches, or deemed savings.
    (iv) All electricity savings must be quantified by applying one or 
more of the following methods: PB-MV, comparison group approaches, or 
deemed savings.
    (A) If a comparison group approach is used, then the EM&V plan must 
quantify electricity savings by taking the difference between a 
comparison group's electricity use and the electricity use of EE 
program participants. Comparison group approaches may include 
randomized control trials and quasi-experimental methods, as described 
in industry best-practice protocols and guidelines. Examples of such 
protocols and guidelines provided in EM&V guidance that may be issued 
by the Administrator will be acceptable.
    (B) If deemed savings are used, then the EM&V plan must specify 
that the deemed savings values will only be used for the specific EE 
measure for which they were derived. The EM&V plan must also specify 
the name and Web address of the technical reference manual (TRM) in 
which all deemed electricity savings values will be documented. Prior 
to use in an EM&V plan, all TRMs must undergo a review process in which 
the public, stakeholders, and experts are invited--with adequate 
advance notification (via the internet and other social media)--to 
provide comment, have at least 2 months to provide comment, and in 
which all such comments and associated responses are made publicly 
available. All TRMs must also be publicly accessible over the full 
period of time in which they are being used in conjunction with an EM&V 
plan for the purpose of quantifying savings, and must be subsequently 
updated in the same manner at least every 3 years. The TRM must 
indicate, for each subject EE measure, the associated electricity 
savings value, the conditions under which the value can be applied 
(including the climate zone, building type, manner of implementation, 
applicable end uses, operating conditions, and effective useful life), 
and the manner in which the electricity savings value was quantified, 
which must include applicable engineering algorithms, source 
documentation, specific assumptions, and other relevant

[[Page 65073]]

data to support the quantification of savings from the subject EE 
measure.
    (v) All EE programs, EE projects, or EE measures must be quantified 
at time intervals (in years) sufficient to ensure that MWh savings are 
accurately and reliably quantified. Such time intervals must be 
specified and explained in the EM&V plan. Factors that must be taken 
into consideration when determining the appropriate time interval 
include the characteristics of the specific EE program, EE project, or 
EE measure, expected variability in electricity savings (where greater 
variability necessitates more frequent quantification), the expected 
scale and magnitude of the electricity savings (where greater 
quantities of savings necessitate more frequent quantification), and 
the experience implementing and quantifying savings from the resource 
(where less experience--for example, with new and innovative EE program 
types--necessitates more frequent quantification). The time intervals 
must end no sooner than the last day of the effective useful life of 
the EE program, EE project, or EE measure, and must last no longer 
than:
    (A) Every 4-year intervals for building energy codes and product 
standards;
    (B) Every 1, 2 or 3 years for public or consumer-funded EE program, 
EE project, or EE measure, as relevant for the type of EE program, EE 
project, or EE measure and factors listed in paragraph (c)(7)(v) of 
this section; and
    (C) Annually for commercial and industrial projects, unless the 
resource provider can provide a reasonable justification in the EM&V 
plan for why an annual time interval is not feasible, and can 
additionally explain how the accuracy and reliability of savings values 
will not be lessened.
    (vi) EM&V plans must specify and document how the EM&V components 
in paragraphs (c)(7)(vi)(A) through (E) of this section will be 
analyzed, considered, or otherwise addressed in the quantification and 
verification of electricity savings.
    (A) The effects of changes in independent factors on reported 
electricity savings (i.e., factors that are not directly related to the 
EE measure, such as weather, occupancy, and production levels).
    (B) The effective useful life (EUL) or duration of time the EE 
measure is anticipated to remain in place and operable with the 
potential to save electricity, which must be based on the application 
of EM&V methods, an industry best-practice persistence study, deemed 
estimates of effective useful life, or a combination of all three.
    (1) If deemed estimates of effective useful life are used, then 
they must specify the date by which the EE measure will stop saving 
electricity.
    (2) If industry best-practices persistence studies are used to 
modify an effective-useful-life value, then they must be conducted at 
least every 5 years.
    (C) The potential sources of double counting, and the associated 
steps for avoiding and correcting for it, such as:
    (1) For an EE program or EE project with identified participants, 
track the type and number of EE measures implemented at the utility-
customer level.
    (2) For an EE program or EE project without identified 
participants, such as point-of-sale rebates and retailer or 
manufacturer incentive programs, track applicable vendor, retailer, and 
manufacturer data.
    (3) For EE programs (such as those implemented by a utility) and EE 
projects (such as those implemented by an energy service company) that 
both have identified participants, use tracking data to avoid and 
correct for double counting that may occur across the two; and
    (4) For EE programs with identified participants and those without 
(such as retail incentives to purchase energy-efficient equipment), use 
EE program tracking data for the former and use applicable vendor, 
retailer, and manufacturer data for the latter to avoid and correct for 
double counting that may occur across the two.
    (D) The EE savings verification approaches for ensuring that EE 
measures have been properly installed, are operating as intended, and 
therefore have the potential to save electricity, including how 
verification will be carried out within the first year of 
implementation of the EE program, EE project, or EE measure using best-
practice approaches, such as physical inspections at a customer's 
premises, phone and mail surveys, and reviews of sales receipts and 
other documentation. If such approaches are documented in EM&V guidance 
issued by the Administrator, they will be treated as acceptable.
    (E) The interactive effects of EE programs, EE projects, or EE 
measures on electricity usage, which are increases or decreases in 
electricity usage at an end-use facility or premises that occurs 
outside of specific end-uses(s) targeted by the EE program, EE project, 
or EE measure (e.g., lighting retrofits to improve EE can reduce waste 
heat to the surrounding conditioned space, and therefore may increase 
the required electric heating load in a facility or premises).
    (vii) The EM&V plan must specify how the accuracy and reliability 
of the electricity savings of the EE program, EE project, or EE measure 
will be assessed, and must discuss the rigor of the method selected to 
quantify the electricity savings. It must also discuss the approaches 
that will be used to control all relevant types of bias and to minimize 
the potential for systematic and random error, as well as the program- 
or project-specific circumstances in which such bias and error are 
likely to arise. Approaches to minimizing bias and error are provided 
in the EM&V guidance that may be issued by the Administrator will be 
acceptable.
    (viii) If sampling will be used to quantify the electricity savings 
from an EE program, then the MWh estimates derived from sampling must 
have at least 90 percent confidence intervals whose end points are no 
more than +/-10 percent of the estimate, and the statistical precision 
of the associated estimates must be specified in the EM&V plan.
    (ix) All data sources and key assumptions used to quantify 
electricity savings must be described in the EM&V plan.
    (x) Any additional information necessary to demonstrate that the 
electricity savings were appropriately quantified and verified. 
Approaches to quantifying and verifying savings from several EE program 
and EE project types that are provided in EM&V guidance that may be 
issued by the Administrator will be acceptable.
    (d) You must ensure that any EM&V plan submitted pursuant to this 
subpart includes the following certification:
    (1) ``I certify under penalty of law that I have personally 
examined, and am familiar with, the statements and information 
submitted in this document and all its attachments. Based on my inquiry 
of those individuals with primary responsibility for obtaining the 
information, I certify that the statements and information are to the 
best of my knowledge and belief true, accurate, and complete. I am 
aware that there are significant penalties for submitting false 
statements and information or omitting required statements and 
information, including the possibility of fine or imprisonment.''

    (2) [Reserved]


Sec.  62.16270  What are the requirements for verification reports?

    (a) A verification report included as part of an eligibility 
application or an M&V report must meet the requirements of paragraph 
(b) of this section (for the eligibility application verification 
report) and paragraph (c) of this section (for the M&V report 
verification report) and include the following:
    (1) A verification statement that sets forth the findings of the 
accredited independent verifier, based on the verifier's assessment of 
the information and data in the eligibility application or M&V report 
that is the subject of the verification report, including an assessment 
of whether the eligibility application or M&V report contains any 
material misstatements or material data discrepancies, and whether the 
submittal conforms with applicable regulatory requirements. The 
verification statement must clearly identify how levels of assurance 
and materiality are defined as part of the verifier assessment.
    (2) The following statement, signed by the accredited independent 
verifier: ``I certify under penalty of law that I have personally 
examined, and am familiar with, the statements and information 
submitted in this document and all its attachments. Based on my 
personal knowledge and/or inquiry of those individuals with primary 
responsibility for obtaining the information, I certify that the 
statements and information are to the best of my knowledge and belief 
true, accurate, and complete. I am aware that there are significant 
penalties for submitting false statements and information or omitting 
required statements and information, including the possibility of fine 
or imprisonment.''
    (b) A verification report included as part of an eligibility 
application must, at a minimum, describe the review conducted by the 
accredited independent verifier and verify each of the following:
    (1) The eligibility of the eligible resource to be issued set-aside 
allowances pursuant to this regulation, in accordance with Sec.  
62.16245(a), including an analysis of the adequacy and validity of the 
information submitted by the authorized account representative to 
demonstrate that the eligible resource meets each applicable 
requirement of Sec.  62.16245;
    (2) The eligible resource is not duplicative of a resource used to 
meet emission standards or a state measure in another approved State 
plan;
    (3) The eligible resource exists or the operation or activity will 
be implemented in the manner specified in the eligibility application;
    (4) That the EM&V plan meets the requirements of Sec.  62.16260;
    (5) Disclosure of any mandatory or voluntary programs to which data 
is reported relating to the eligible resource (e.g., reporting of 
electric generation by a renewable energy resource to a renewable 
energy certificate tracking system); and
    (6) Any other information required by the Administrator or that the 
accredited independent verifier finds, in its professional opinion, is 
necessary to assess the adequacy and validity of information and data 
supplied by the authorized account representative.
    (c) A verification report included as part of an M&V report must, 
at a minimum, describe the review conducted by the accredited 
independent verifier and verify the information specified in paragraphs 
(c)(1) through (3) of this section.
    (1) The adequacy and validity of the information and data submitted 
in the submittal by the authorized account representative to quantify 
eligible MWh of electric generation or electricity savings during the 
period for which the authorized account representative seeks issuance 
of set-aside allowances, as well as all supporting information and data 
identified in the EM&V plan and M&V report. This analysis must include 
a quality assurance and quality control check of the data and ensure 
that all generation or savings data is within a technically feasible 
range for that specific eligible resource.
    (i) For metered generation, the data validity check must compare 
reported electricity generation to an engineering estimate of the 
maximum generation potential of the qualified renewable energy 
resource, based on, at a minimum, its maximum nameplate capacity in MW 
and the number of days since the prior cumulative meter reading was 
entered in the allowance tracking system. If the data entered exceeds 
the estimated technically feasible generation, then the reported data 
and the estimate must be analyzed in the verification report.
    (ii) For all electricity generated or saved, the accredited 
independent verifier must describe the likely source of any data 
discrepancy and determine

[[Page 65075]]

in the verification report any MWh generated or saved.
    (2) The M&V report meets the requirements of Sec.  62.16265.
    (3) Any other information required by the Administrator or that the 
accredited independent verifier finds, in its professional opinion, is 
necessary to assess the adequacy and validity of information and data 
supplied by the authorized account representative.


Sec.  62.16275  What is the accreditation procedure for independent 
verifiers?

    (a) Only Administrator-accredited independent verifiers may provide 
a verification report for an eligibility application or M&V report.
    (b) Applications for accreditation must follow a procedure and form 
specified by the Administrator which includes a demonstration by the 
verifier that it meets the requirements in paragraph (c) of this 
section.
    (c) Independent verifiers must meet each of the requirements in 
paragraphs (c)(1) through (6) of this section to be accredited.
    (1) Independent verifiers must have the skills, experience, 
resources (personnel and otherwise) to provide verification reports, 
including the following:
    (i) Appropriate technical qualification (professional engineer or 
otherwise) to evaluate the eligible resource for which the independent 
verifier is seeking accreditation, which may include ANSI accreditation 
under ISO 14065 for GHG validation and verification bodies;
    (ii) Appropriate auditing and accounting qualifications for 
financial and non-financial data monitoring, auditing, and quality 
assurance and quality control to evaluate the eligible resource for 
which the independent verifier is seeking accreditation;
    (iii) Knowledge of the requirements of the Administrator's 
CO2 Mass-based Trading Program regulations and related 
guidance;
    (iv) Knowledge of the eligible resource categories for which the 
independent verifier is seeking accreditation, including relevant 
aspects of the design, operation, and related energy generation or 
electricity savings monitoring and reporting approaches for such 
eligible resources; and
    (v) Capability to perform key verification activities, such as 
development of a verification report; site visits; review and 
recalculation of reported data; review of data management systems; 
review of quantification methods used in accordance with an approved 
EM&V plan; preparation of a verification opinion, list of findings, and 
verification report; and internal review of the verification findings 
and report.
    (2) Independent verifiers must document, in the application for 
accreditation, the independent verifiers that will provide verification 
services, including lead verifiers, key personnel and any contractors 
or subcontractors (collectively, accredited independent verification 
team) and demonstrate that they meet the requirements of paragraph 
(c)(1) of this section. Once accredited, only the accredited 
independent verification team identified in the accreditation 
application and accredited by the State may provide a verification 
report.
    (3) An independent verifier must specify the eligible resource 
categories for which it is seeking accreditation, and an accredited 
independent verifier may only provide verification services related to 
an eligible resource category for which it is accredited.
    (4) Prospective independent verifiers must meet the requirements of 
Sec.  62.16280(d) through (f) and demonstrate that they have in place 
adequate systems and protocols to identify, disclose and avoid 
potential conflicts of interest.
    (5) An accredited independent verifier must not be debarred, 
suspended, or proposed for debarment pursuant to the Government-wide 
Debarment and Suspension regulations, 40 CFR part 32 of this chapter, 
or the Debarment, Suspension and Ineligibility provisions of the 
Federal Acquisition Regulations, 48 CFR part 9, subpart 9.4.
    (6) An accredited independent verifier must maintain, for its 
employees, and ensure the maintenance of, for any parties that it 
employs, professional liability insurance, as defined in 31 CFR 
50.5(q), through an insurance provider that possesses a financial 
strength rating in the top four categories from either Standard & 
Poor's or Moody's, specifically, AAA, AA, A or BBB for Standard & 
Poor's, and Aaa, Aa, A, or Baa for Moody's. Any entity covered by this 
paragraph must disclose the level of professional liability insurance 
they possess when entering into contracts to provide verification 
services pursuant to this regulation.
    (d) Requirements for maintenance of accreditation status.
    (1) Accredited independent verifiers must meet the requirements of 
Sec.  62.16280 when providing verification services for an authorized 
account representative.
    (2) The instances specified in Sec.  62.16280(d) are cause for 
revocation of a verifier's accreditation.


Sec.  62.16280  What are the procedures accredited independent 
verifiers must follow to avoid conflict of interest?

    (a) Accredited independent verifiers must not provide verification 
services for any eligible resource for which it has a conflict of 
interest (COI), which means:
    (1) Accredited independent verifiers must have, or have had, no 
direct or indirect financial interest in, or other financial 
relationships with, an eligible resource, or any prospective eligible 
resource, for which they seek to provide a verification report;
    (2) Accredited independent verifiers must have, or have had, no 
direct or indirect organizational or personal relationships with an 
eligible resource, that would impact their impartiality in assessing 
the validity and accuracy of the information in an eligibility 
application or M&V report;
    (3) Accredited independent verifiers must have, or have had, no 
role in the development and implementation of an eligible resource for 
which an authorized account representative seeks issuance of set-aside 
allowances, beyond the provision of verification services;
    (4) Accredited independent verifiers must not be compensated, 
financially or otherwise, directly or indirectly, on the basis of the 
content of its verification report (including eligibility approval of 
an eligible resource, the quantified and verified MWh in an M&V report, 
set-aside allowance issuance, or the number of set-aside allowances 
issued);
    (5) Accredited independent verifiers must not own, buy, sell, or 
hold set-aside allowances, or other financial derivatives related to 
set-aside allowances, or have a financial relationship with other 
parties that own, buy, sell, or hold set-aside allowances or other 
related financial derivatives;
    (6) An accredited independent verifier must not be incapable of 
providing an impartial verification report for any other reason; and
    (7) An accredited independent verifier must ensure that the subject 
of any verification report must not have the opportunity to review or 
influence any draft or final verification report before its submittal 
to the Administrator, and the accredited independent verifier must 
share any drafts of its reports with the Administrator at the same time 
as it shares them with the subject of the report.
    (b) A contract with an eligible resource for the provision of 
verification services will not constitute a COI.
    (c) Verification reports must include an attestation by the 
accredited independent verifier that it evaluated

[[Page 65076]]

and disclosed to the Administrator any potential COI related to an 
eligible resource.
    (d) Prior to engaging for the provision of verification services, 
an accredited independent verifier must demonstrate that it has no COI 
related to the eligible resource, as specified in paragraph (a) of this 
section. If a COI is identified for a person or persons within an 
accredited independent verifier for a specific subject or verification, 
in accordance with paragraphs (e) and (f) of this section, then an 
accredited independent verifier may propose to the Administrator steps 
that will be taken to eliminate the COI, which include prohibiting the 
person or persons with the conflict from any involvement in the matter 
subject to the conflict, including verification services, access to 
information related to the verification services, access to any draft 
or final verification reports, any communications with the person(s) 
conducting the verification services. In no instance shall an 
accredited independent verifier engage in verification services for an 
eligible resource without the approval of the Administrator.
    (e) Prior to engaging in verification services and writing a 
verification report, an accredited independent verifier must disclose 
to the Administrator all information necessary for the Administrator to 
evaluate a potential COI (including information concerning its 
ownership, past and current clients, related entities, as well as any 
other facts or circumstances that have the potential to create a COI).
    (f) Accredited verifiers have an ongoing obligation to disclose to 
the Administrator any facts or circumstances that may give rise to a 
COI as defined in paragraph (a) of this section.
    (g) The Administrator may reject a verification report from an 
accredited independent verifier, if the Administrator determines that 
the accredited independent verifier has a COI as defined in paragraph 
(a) of this section. If the Administrator rejects an accredited 
independent verifier report for such reasons, then the eligibility 
application or M&V report submittal shall be deemed incomplete and set-
aside allowances must not be issued pursuant to it.


Sec.  62.16285  What is the process for the revocation of accreditation 
status for an independent verifier?

    (a) The Administrator may revoke the accreditation of an 
independent verifier at any time for cause, including for the reasons 
specified in paragraphs (a)(1) through (4) of this section.
    (1) Failure to fully disclose any issues that may lead to a COI 
with respect to an eligible resource, or other related entity, in 
accordance with Sec.  62.16280(d) through (f).
    (2) The accredited independent verifier is no longer qualified to 
provide verification services.
    (3) Negligence in the conduct of verification activities, or 
neglect of responsibilities pursuant to the requirements of Sec. Sec.  
62.16270, 62.16275, and 62.16280.
    (4) Intentional misrepresentation of data in a verification report.
    (b) [Reserved]

designated representative or any alternate designated representative.


Sec.  62.16295  What responsibilities do designated representatives and 
alternate designated representatives hold?

    (a) Except as provided under Sec.  62.16315 concerning delegation 
of authority to make submissions, each submission under the 
CO2 Mass-based Trading Program shall be made, signed, and 
certified by the designated representative or alternate designated 
representative for each facility and affected EGU for which the 
submission is made. Each such submission must include the following 
certification statement by the designated representative or alternate 
designated representative: ``I am authorized to make this submission on 
behalf of the owners and operators of the facility or affected EGUs for 
which the submission is made. I certify under penalty of law that I 
have personally examined, and am familiar with, the statements and 
information submitted in this document and all its attachments. Based 
on my inquiry of those individuals with primary responsibility for 
obtaining the information, I certify that the statements and 
information are to the best of my knowledge and belief true, accurate, 
and complete. I am aware that there are

[[Page 65077]]

significant penalties for submitting false statements and information 
or omitting required statements and information, including the 
possibility of fine or imprisonment.''
    (b) The Administrator will accept or act on a submission made for a 
facility or an affected EGU only if the submission has been made, 
signed, and certified in accordance with paragraph (a) of this section 
and Sec.  62.16315.


Sec.  62.16300  What are the processes for changing designated 
representative, alternate designated representative, owners and

    (b) Deductions for compliance. After the recordation, in accordance 
with Sec.  62.16335, of CO2 allowance transfers submitted by 
the allowance transfer deadline for a compliance period, the 
Administrator will deduct from each facility's compliance account 
CO2 allowances available under paragraph (a) of this section 
in order to determine whether the facility meets the CO2 
emission standard for such compliance period, as follows:
    (1) Until the amount of CO2 allowances deducted equals 
the number of tons of total CO2 emissions from all affected 
EGUs at the facility for such compliance period; or
    (2) If there are insufficient CO2 allowances to complete 
the deductions in paragraph (b)(1) of this section, until no more 
CO2 allowances available under paragraph (a) of this section 
remain in the compliance account.
    (c)(1) Identification of CO2 allowances by serial 
number. The authorized account representative for a facility's 
compliance account may request that specific CO2 allowances, 
identified by serial number, in the compliance account be deducted for 
emissions or excess emissions for a compliance period in accordance 
with paragraph (b) or (d) of this section. In order to be complete, 
such request must be submitted to the Administrator by the allowance 
transfer deadline for such compliance period and include, in a format 
prescribed by the Administrator, the identification of the facility and 
the appropriate serial numbers.
    (2) First-in, first-out. The Administrator will deduct 
CO2 allowances under paragraph (b) or (d) of this section 
from the facility's compliance account in accordance with a complete 
request under paragraph (c)(1) of this section or, in the absence of 
such request or in the case of identification of an insufficient amount 
of CO2 allowances in such request, on a first-in, first-out 
accounting basis in the following order:
    (i) Any CO2 allowances that were allocated to the 
affected EGUs at the facility and not transferred out of the compliance 
account, in the order of recordation; and then
    (ii) Any CO2 allowances that were allocated to any 
affected EGU or other entity and transferred to and recorded in the 
compliance account pursuant to this subpart, in the order of 
recordation.
    (d) Deductions for excess emissions. After making the deductions 
for compliance under paragraph (b) of this section for a compliance 
period in a year in which the facility has excess emissions, the 
Administrator will deduct from the facility's compliance account an 
amount of CO2 allowances, allocated for a compliance period 
in a prior year or the compliance period in the year of the excess 
emissions or in the immediately following year, equal to two times the 
number of tons of the facility's excess emissions.

[[Page 65082]]

    (e) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account 
under paragraphs (b) and (d) of this section.


Sec.  62.16345  What monitoring requirements must I comply with?

    (a) The owner or operator of an affected EGU must prepare a 
monitoring plan in accordance with the applicable provisions in Sec.  
75.53(g) and (h) of this chapter, unless such a plan is already in 
place under another program that requires CO2 mass emissions 
to be monitored and reported according to part 75 of this chapter. You 
must follow the requirements described in paragraphs (a)(1) through (8) 
of this section to monitor emissions and net energy output at your 
affected EGU.
    (1) For each operating hour, calculate the hourly CO2 
mass (tons) according to paragraph (a)(4) or (5) of this section, 
except that a complete data record is required, i.e., CO2 
mass emissions must be reported for each operating hour. Therefore, 
substitute data values recorded under part 75 of this chapter for 
CO2 concentration, stack gas flow rate, stack gas moisture 
content, fuel flow rate and/or gross calorific value (GCV) must be used 
in the calculations; and
    (2) Sum all of the hourly CO2 mass emissions values over 
the entire compliance period.
    (3) The owner or operator of an affected EGU must install, 
calibrate, maintain, and operate a sufficient number of watt meters to 
continuously measure and record on an hourly basis net electric output. 
Measurements must be performed using 0.2 accuracy class electricity 
metering instrumentation and calibration procedures as specified under 
ANSI Standards No. C12.20. Further, the owner or operator of an 
affected EGU that is a combined heat and power facility must install, 
calibrate, maintain and operate equipment to continuously measure and 
record on an hourly basis useful thermal output and, if applicable, 
mechanical output, which are used with net electric output to determine 
net energy output (Pnet). The owner or operator must 
calculate net energy output according to paragraphs (a)(6)(i)(A) and 
(B) of this section.
    (4) The owner or operator of an affected EGU must measure and 
report the hourly CO2 mass emissions (lbs) from each 
affected unit using the procedures in paragraphs (a)(4)(i) through (vi) 
of this section, except as otherwise provided in paragraph (a)(5) of 
this section.
    (i) The owner or operator of an affected EGU must install, certify, 
operate, maintain, and calibrate a CO2 continuous emissions 
monitoring system (CEMS) to directly measure and record CO2 
concentrations in the affected EGU exhaust gases emitted to the 
atmosphere and an exhaust gas flow rate monitoring system according to 
Sec.  75.10(a)(3)(i) of this chapter. However, when an O2 
monitor is used this way, it only quantifies the combustion 
CO2; therefore, if the EGU is equipped with emission 
controls that produce non-combustion CO2 (e.g., from sorbent 
injection), then this additional CO2 must be accounted for, 
in accordance with section 3 of appendix G to part 75 of this chapter. 
As an alternative to direct measurement of CO2 
concentration, provided that the affected EGU does not use carbon 
separation (e.g., carbon capture and storage), the owner or operator of 
an affected EGU may use data from a certified oxygen (O2) 
monitor to calculate hourly average CO2 concentrations, in 
accordance with Sec.  75.10(a)(3)(iii) of this chapter. If 
CO2 concentration is measured on a dry basis, then the owner 
or operator of the affected EGU must also install, certify, operate, 
maintain, and calibrate a continuous moisture monitoring system, 
according to Sec.  75.11(b) of this chapter. Alternatively, the owner 
or operator of an affected EGU may either use an appropriate fuel-
specific default moisture value from Sec.  75.11(b) or submit a 
petition to the Administrator under Sec.  75.66 of this chapter for a 
site-specific default moisture value.
    (ii) Calculate the hourly CO2 mass emission rate (tons/
hr), either from Equation F-11 in Appendix F to part 75 of this chapter 
(if CO2 concentration is measured on a wet basis), or by 
following the procedure in section 4.2 of Appendix F to part 75 of this 
chapter (if CO2 concentration is measured on a dry basis). 
CO2 mass emissions must be reported for each operating hour. 
Therefore, substitute data values recorded under part 75 of this 
chapter for CO2 concentration, stack gas flow rate, stack 
gas moisture content, fuel flow rate and/or GCV must be used in the 
calculations.
    (iii) Next, multiply each hourly CO2 mass emission rate 
by the EGU or stack operating time in hours (as defined in Sec.  72.2 
of this chapter), to convert it to tons of CO2. Multiply the 
result by 2000 lb/ton to convert it to lb.
    (iv) The hourly CO2 tons/hr values and EGU (or stack) 
operating times used to calculate CO2 mass emissions are 
required to be recorded under Sec.  75.57(e) of this chapter and must 
be reported electronically under Sec.  75.64(a)(6) of this chapter, if 
required by a plan. The owner or operator must use these data, or 
equivalent data, to calculate the hourly CO2 mass emissions.
    (v) Sum all of the hourly CO2 mass emissions values that 
were calculated according to procedures specified in paragraph 
(a)(4)(ii) of this section over the entire compliance period.
    (vi) For each continuous monitoring system used to determine the 
CO2 mass emissions from an affected EGU, the monitoring 
system must meet the applicable certification and quality assurance 
procedures in Sec.  75.20 of this chapter and Appendices A and B to 
part 75 of this chapter.
    (5) The owner or operator of an affected EGU that exclusively 
combusts liquid fuel and/or gaseous fuel may, as an alternative to 
complying with paragraph (a)(4) of this section, determine the hourly 
CO2 mass emissions according to paragraphs (a)(5)(i) through 
(vi) of this section.
    (i) Implement the applicable procedures in appendix D to part 75 of 
this chapter to determine hourly EGU heat input rates (MMBtu/h), based 
on hourly measurements of fuel flow rate and periodic determinations of 
the gross calorific value (GCV) of each fuel combusted. The fuel flow 
meter(s) used to measure the hourly fuel flow rates must meet the 
applicable certification and quality-assurance requirements in sections 
2.1.5 and 2.1.6 of appendix D (except for qualifying commercial billing 
meters). The fuel GCV must be determined in accordance with section 2.2 
or 2.3 of appendix D, as applicable.
    (ii) For each measured hourly heat input rate, use Equation G-4 in 
Appendix G to part 75 of this chapter to calculate the hourly 
CO2 mass emission rate (tons/hr).
    (iii) Determine the hourly CO2 mass emission rate (tons/
hr) using the procedures specified in paragraph (a)(4)(ii) of this 
section and multiply it by the EGU or stack operating time in hours (as 
defined in Sec.  72.2 of this chapter), to convert to tons of 
CO2. Then, multiply the result by 2000 lb/ton to convert to 
lb.
    (iv) The hourly CO2 tons/hr values and EGU (or stack) 
operating times used to calculate CO2 mass emissions are 
required to be recorded under Sec.  75.57(e) of this chapter and must 
be reported electronically under Sec.  75.64(a)(6), if required by a 
plan. You must use these data, or equivalent data, to calculate the 
hourly CO2 mass emissions.
    (v) Sum all of the hourly CO2 mass emissions values (lb) 
that were calculated according to procedures specified in paragraph 
(a)(5)(iii) of this

[[Page 65083]]

section over the entire compliance period.
    (vi) The owner or operator of an affected EGU may determine site-
specific carbon-based F-factors (Fc) using Equation F-7b in 
section 3.3.6 of appendix F to part 75 of this chapter, and may use 
these Fc values in the emissions calculations instead of 
using the default Fc values in the Equation G-4 
nomenclature.
    (6) The owner or operator of an affected EGU must install, 
calibrate, maintain, and operate a sufficient number of watt meters to 
continuously measure and record on an hourly basis net electric output. 
Measurements must be performed using 0.2 accuracy class electricity 
metering instrumentation and calibration procedures as specified under 
ANSI Standards No. C12.20. Further, the owner or operator of an 
affected EGU that is a combined heat and power facility must install, 
calibrate, maintain and operate equipment to continuously measure and 
record on an hourly basis useful thermal output and, if applicable, 
mechanical output, which are used with net electric output to determine 
net energy output. The owner or operator must calculate net energy 
output according to paragraph (a)(6)(i) of this section.
    (i) For each operating hour of a compliance period that was used in 
paragraph (a)(4) or (5) of this section to calculate the total 
CO2 mass emissions, you must determine Pnet (the 
corresponding hourly net energy output in MWh) according to the 
procedures in paragraphs (a)(6)(i)(A) and (B) of this section, as 
appropriate for the type of affected EGU(s). For an operating hour in 
which a valid CO2 mass emissions value is determined 
according to paragraph (a)(4) or (5) of this section, if there is no 
gross or net electrical output, but there is mechanical or useful 
thermal output, you must still determine the net energy output for that 
hour. In addition, for an operating hour in which a valid 
CO2 mass emissions value is determined according to 
paragraph (a)(4) or (5) of this section, but there is no (i.e., zero) 
gross electrical, mechanical, or useful thermal output, you must use 
that hour in the compliance determination. For hours or partial hours 
where the gross electric output is equal to or less than the auxiliary 
loads, net electric output must be counted as zero for this 
calculation.
    (A) Calculate Pnet for your affected EGU using the 
following equation. All terms in the equation must be expressed in 
units of megawatt-hours (MWh). To convert each hourly net energy output 
value reported under part 75 of this chapter to MWh, multiply by the 
corresponding EGU or stack operating time.
[GRAPHIC] [TIFF OMITTED] TP23OC15.016

Where:

Pnet = Net energy output of your affected EGU in MWh.
(Pe)ST = Electric energy output plus mechanical energy 
output (if any) of steam turbines in MWh.
(Pe)CT = Electric energy output plus mechanical energy 
output (if any) of stationary combustion turbine(s) in MWh.
(Pe)IE = Electric energy output plus mechanical energy 
output (if any) of your affected EGU's integrated equipment that 
provides electricity or mechanical energy to the affected EGU or 
auxiliary equipment in MWh.
(Pe)A = Electric energy used for any auxiliary loads in 
MWh.
(Pt)PS = Useful thermal output of steam (measured 
relative to SATP conditions as defined in Sec.  62.16375, as 
applicable) that is used for applications that do not generate 
additional electricity, produce mechanical energy output, or enhance 
the performance of the affected EGU. This is calculated using the 
equation specified in paragraph (a)(6)(i)(B) of this section in MWh.
(Pt)HR = Non steam useful thermal output (measured 
relative to SATP conditions as defined in Sec.  62.16375, as 
applicable) from heat recovery that is used for applications other 
than steam generation or performance enhancement of the affected EGU 
in MWh.
(Pt)IE = Useful thermal output (relative to SATP 
conditions as defined in Sec.  62.16375, as applicable) from any 
integrated equipment that is used for applications that do not 
generate additional steam, electricity, produce mechanical energy 
output, or enhance the performance of the affected EGU in MWh.
TDF = Electric Transmission and Distribution Factor of 0.95 for a 
combined heat and power affected EGU where at least on an annual 
basis 20.0 percent of the total net energy output consists of 
electric or direct mechanical output and 20.0 percent of the total 
net energy output consists of useful thermal output on a 12-
operating month rolling average basis, or 1.0 for all other affected 
EGUs.

    (B) If applicable to your affected EGU (for example, for combined 
heat and power), you must calculate (Pt)PS using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TP23OC15.017

Where:

(Pt)ps = Useful thermal output of steam (measured 
relative to SATP conditions as defined in Sec.  62.16375, as 
applicable) that is used for applications that do not generate 
additional electricity, produce mechanical energy output, or enhance 
the performance of the affected EGU.
Qm = Measured steam flow in kilograms (kg) (or pounds 
(lb)) for the operating hour.

(relative to SATP conditions as defined in Sec.  62.16375 or the 
energy in the condensate return line, as applicable) in Joules per 
kilogram (J/kg) (or Btu/lb).
CF = Conversion factor of 3.6 x 10\9\ J/MWh or 3.413 x 10\6\ Btu/
MWh.

    (ii) [Reserved]
    (7) In accordance with Sec.  60.13(g), if two or more affected EGUs 
implementing the continuous emissions monitoring provisions in 
paragraph (a)(1) of this section share a common exhaust gas stack and 
are subject to the same emissions standard, then the owner or operator 
may monitor the hourly CO2 mass emissions at the common 
stack in lieu of monitoring each EGU separately. If an owner or 
operator of an affected EGU chooses this option, then the hourly net 
electric output for the common stack must be the sum of the hourly net 
electric output of the individual affected facility and the operating 
time must be expressed as ``stack operating hours'' (as defined in 
Sec.  72.2 of this chapter).
    (8) In accordance with Sec.  60.13(g), if the exhaust gases from an 
affected EGU implementing the continuous emissions monitoring 
provisions in paragraph (a)(3) of this section are emitted to the 
atmosphere through multiple stacks (or if the exhaust gases are routed 
to a common stack through multiple ducts and you elect to monitor in 
the ducts), the hourly CO2 mass emissions and the ``stack 
operating time'' (as defined in Sec.  72.2 of this chapter) at each 
stack or duct must be monitored separately. In this case, the owner or 
operator of an affected EGU must determine compliance with an 
applicable emissions standard by summing the CO2 mass 
emissions measured at the individual stacks or ducts and dividing by 
the net energy output for the affected EGU.

[[Page 65084]]

    (b) [Reserved]

Introduction


Sec.  62.16405  What is the purpose of this subpart?

    (a) This subpart sets forth the requirements for the Clean Power 
Plan (CPP) CO2 Rate-based Trading Program, under section 111 
of the Clean Air Act and subpart UUUU of part 60 of this chapter, as a 
means of meeting emission guidelines limiting greenhouse gas emissions 
from an affected steam generating unit, integrated gasification 
combined cycle (IGCC), or stationary combustion turbine.

[[Page 65091]]

    (b) The pollutants regulated by this subpart are greenhouse gases. 
The greenhouse gas limitations in this subpart are in the form of an 
emission standard for carbon dioxide (CO2).
    (c) PSD and Title V thresholds for greenhouse gases. (1) For the 
purposes of Sec.  51.166(b)(49)(ii) of this chapter, with respect to 
GHG emissions from affected facilities, the ``pollutant that is subject 
to the standard promulgated under section 111 of the Act'' shall be 
considered to be the pollutant that otherwise is subject to regulation 
under the Act as defined in Sec.  51.166(b)(48) of this chapter and in 
any state implementation plan approved by the EPA that is interpreted 
to incorporate, or specifically incorporates, Sec.  51.166(b)(48) of 
this chapter.
    (2) For the purposes of Sec.  52.21(b)(50)(ii) of this chapter, 
with respect to GHG emissions from affected facilities, the ``pollutant 
that is subject to the standard promulgated under section 111 of the 
Act'' shall be considered to be the pollutant that otherwise is subject 
to regulation under the Act as defined in Sec.  52.21(b)(49) of this 
chapter.
    (3) For the purposes of Sec.  70.2 of this chapter, with respect to 
greenhouse gas emissions from affected facilities, the ``pollutant that 
is subject to any standard promulgated under section 111 of the Act'' 
shall be considered to be the pollutant that otherwise is ``subject to 
regulation'' as defined in Sec.  70.2 of this chapter.
    (4) For the purposes of Sec.  71.2 of this chapter, with respect to 
greenhouse gas emissions from affected facilities, the ``pollutant that 
is subject to any standard promulgated under section 111 of the Act'' 
shall be considered to be the pollutant that otherwise is ``subject to 
regulation'' as defined in Sec.  71.2 of this chapter.

Applicability of This Subpart


Sec.  62.16410  Am I subject to this subpart?

    (a) You are subject to this subpart if you are the owner or 
operator of an affected electric generating unit (EGU) located within a 
State that has incorporated by reference this subpart as a State plan, 
or portion of a State plan, that has been approved by the Administrator 
and is effective under subpart UUUU of part 60 of this chapter, or if 
this subpart is promulgated and effective as a federal plan in your 
State under part 62 of this chapter.
    (b) An affected EGU is any steam generating unit, IGCC, or 
stationary combustion turbine that meets the applicability requirements 
in Sec. Sec.  60.5840(b) and 60.5845 of this chapter.


Sec.  62.16415  What are the requirements for retired affected EGUs?

    (a) Exemption. (1) Any affected EGU that is permanently retired as 
defined in Sec.  62.16570 is exempt from Sec. Sec.  62.16420(c)(1) 
[CO2 Emissions Requirements], 62.16535 [Compliance 
Requirements], 62.16540 [Monitoring], 62.16555 [Reporting], and 
62.16560 [Recordkeeping].
    (2) The exemption under paragraph (a)(1) of this section will 
become effective on the first day of the compliance period immediately 
following the compliance period in which the retirement took effect. 
Within 30 days of the affected EGU's permanent retirement, the 
designated representative must submit a statement to the Administrator. 
The statement must state, in a format prescribed by the Administrator, 
that the affected EGU was permanently retired on a specified date and 
will comply with the requirements of paragraph (b) of this section.
    (b) Special provisions. (1) An affected EGU exempt under paragraph 
(a) of this section must not emit any CO2, starting on the 
date that the exemption takes effect.
    (2) For a period of 5 years from the date the records are created, 
the owners and operators of an affected EGU exempt under paragraph (a) 
of this section must retain, at the affected EGU, records demonstrating 
that the affected EGU is permanently retired. The 5-year period for 
keeping records may be extended for cause, at any time before the end 
of the period, in writing by the Administrator. The owners and 
operators bear the burden of proof that the affected EGU is permanently 
retired.
    (3) The owners and operators and, to the extent applicable, the 
designated representative of an affected EGU exempt under paragraph (a) 
of this section must comply with the requirements of the CO2 
Rate-based Trading Program accruing during any compliance periods for 
which the exemption is not in effect, even if such requirements must be 
complied with after the exemption takes effect.

General Requirements


Sec.  62.16420  What emission standards and requirements must I comply 
with?

    (a) Designated representative requirements. The owners and 
operators must have a designated representative, and may have an 
alternate designated representative, in accordance with Sec. Sec.  
62.16485 through 62.16495.
    (b) Emissions monitoring, reporting, and recordkeeping 
requirements. (1) The owners and operators, and the designated 
representative, of affected EGU must comply with the monitoring, 
reporting, and recordkeeping requirements of Sec. Sec.  62.16540, 
62.16555, and 62.16560.
    (2) The emissions data determined in accordance with Sec.  62.16540 
must be used to determine compliance with the CO2 emission 
standard under paragraph (c) of this section, provided that, for each 
monitoring location from which emissions are reported, the emission 
rate used in determining compliance must be the CO2 emission 
rate at the monitoring location determined in accordance with paragraph 
(c) of this section.
    (c) CO2 emission standard requirements. (1) Each designated 
representative for each affected EGU must demonstrate compliance with 
its emission standard listed in Table 1 of this subpart, as applicable, 
by calculating a CO2 emission rate by factoring stack 
emissions and any emission rate credits (ERCs) into the following 
equation:
[GRAPHIC] [TIFF OMITTED] TP23OC15.018


Where:

CO2 emission rate = An affected EGU's calculated 
CO2 emission rate that will be used to determine 
compliance with the applicable CO2 emission standard.
MCO2 = Measured CO2 mass in units of pounds 
(lbs) summed over the compliance period for an affected EGU.
MWhop = Total net energy output over the compliance 
period for an affected EGU in units of MWh.
MWhERC = ERC replacement generation for an affected EGU 
in units of MWh (ERCs are denominated in whole integers as specified 
in paragraph (c)(2) of this section).


[[Page 65092]]


    (2) An ERC qualifies for the compliance demonstration specified in 
paragraph (c)(1) of this section if it:
    (i) Has a unique serial number;
    (ii) Represents one whole MWh of actual energy generated or saved 
with zero associated carbon dioxide emissions;
    (iii) Was issued to an eligible resource that meets the 
requirements of Sec.  62.16435 or to an affected EGU that meets the 
requirements of Sec.  62.16434, by the Administrator through an ERC 
tracking system or the ATCS; and
    (iv) Was surrendered and retired only once for purposes of 
compliance with this regulation by the Administrator through an ERC 
tracking system or the ATCS.
    (3) An ERC does not qualify for the compliance demonstration 
specified in paragraph (c)(1) of this section if it does not meet the 
requirements of paragraph (c)(2) of this section or if any State has 
used that same ERC for purposes of demonstrating achievement of its 
state measures.
    (4) As of the ERC transfer deadline for a compliance period, the 
owners and operators of each affected EGU must hold, in the affected 
EGU's compliance account, sufficient ERCs to demonstrate compliance 
with its applicable emission standard listed in Table 1 of this subpart 
pursuant to the requirement of paragraph (c)(1) of this section.
    (5) If an affected EGU exceeds its emission standard during a 
compliance period, then:
    (i) The owners and operators of the affected EGU must hold ERCs 
required for deduction under Sec.  62.16535(e);
    (ii) The owners and operators of the affected EGU are subject to 
federal enforcement pursuant to sections 113(a)-(h), and section 304, 
of the Clean Air Act, and the United States, States, and other persons 
have the ability to enforce against violations (including if an 
affected EGU does not meet its emission standard based on its 
emissions, or use of ERCs that meet the compliance demonstration in 
Sec.  62.16420 (c)(2)) and secure appropriate corrective actions, and 
the owners and operators must pay any fine, penalty, or assessment or 
comply with any other remedy imposed, for the same violations, under 
the Clean Air Act, and each day of such compliance period will 
constitute a separate violation of this subpart and the Clean Air Act;
    (iii) If an affected EGU does not meet its emission standard 
because it did not meet the emissions standard based on its stack 
emissions and generation alone and it did not obtain sufficient 
qualifying ERCs to meet its emission standard by July 1 of the year 
following the relevant compliance period, then it may be subject to 
federal enforcement pursuant to Sections 113(a)-(h), 42 U.S.C. 7413(a)-
(h), and Section 304 of the Clean Air Act, 42 U.S.C. 7604, and the 
United States, states, and other persons have the ability to enforce 
violations and secure corrective actions; and
    (iv) If an affected EGU obtained sufficient facially valid ERCs to 
meet its emission standard, but those ERCs were found to be invalid, 
then it may be subject to federal enforcement as specified in paragraph 
(c)(5)(iii) of this section.
    (d) Compliance periods. An affected EGU will be subject to the 
requirements under paragraph (c)(1) of this section for the compliance 
period starting on January 1, 2022, and for each compliance period 
thereafter.
    (1) Vintage of ERCs held for compliance. An ERC held for compliance 
with the requirements under paragraph (c)(1) of this section for a 
compliance period must be an ERC that was issued for a year in such 
compliance period or for a year in a prior compliance period.
    (2) ATCS. Each ERC must be held in, deducted from, transferred 
into, out of, or between ATCS accounts in accordance with this subpart.
    (3) Limited authorization. (i) An ERC shall only be used in 
accordance with the CO2 Rate-based Trading Program; and
    (ii) Notwithstanding any other provision of this subpart, the 
Administrator has the authority to terminate or limit the use and 
duration of such authorization to the extent the Administrator 
determines is necessary or appropriate to implement any provision of 
the Clean Air Act.
    (4) Property right. An ERC does not constitute a property right.
    (e) Title V permit requirements. (1) Unless otherwise specified in 
this paragraph, all requirements of this subpart shall be applicable 
requirements that must be included in an affected EGU's title V permit.
    (2) The applicable requirements of this subpart, as well as other 
terms or conditions necessary to ensure compliance with the applicable 
requirements, may be added to, or changed in, a title V permit using 
minor permit modification procedures in accordance with Sec. Sec.  
70.7(e)(2) and 71.7(e)(1) of this chapter, provided that such changes 
do not conflict with any existing terms of the permit. This paragraph 
explicitly provides that the addition of, or change to, an affected 
EGU's description as described in the prior sentence is eligible for 
minor permit modification procedures in accordance with Sec. Sec.  
70.7(e)(2)(i)(B) and 71.7(e)(1)(i)(B) of this chapter.
    (3) No title V permit revision will be required for any crediting, 
holding, deduction, or transfer of ERCs in accordance with this 
subpart, provided that the requirements applicable to such creditings, 
holdings, deductions, or transfers of ERCs are already incorporated in 
such permit.
    (f) Liability. Any provision of the CO2 Rate-based 
Trading Program that applies to an affected EGU or the designated 
representative of an affected EGU shall also apply to the owners and 
operators of such affected EGU.
    (g) Effect on other authorities. No provision of the CO2 
Rate-based Trading Program or exemption under Sec.  62.16415 shall be 
construed as exempting or excluding the owners and operators, and the 
designated representative, of an affected EGU from compliance with any 
other provision of the applicable, approved state implementation plan, 
a federally enforceable permit, or any other requirement of the Clean 
Air Act.


Sec.  62.16425  How should I compute time under the CO2 
Rate-based Trading Program?

    (a) Unless otherwise stated, any time period scheduled, under the 
CO2 Rate-Based Trading Program, to begin on the occurrence 
of an act or event shall begin on the day the act or event occurs.
    (b) Unless otherwise stated, any time period scheduled, under the 
CO2 Rate-Based Trading Program, to begin before the 
occurrence of an act or event will be computed so that the period ends 
the day before the act or event occurs.
    (c) Unless otherwise stated, if the final day of any time period, 
under the CO2 Rate-Based Trading Program, is not a business 
day, then the time period will be extended to the next business day.


Sec.  62.16430  What are the administrative appeal procedures?

    The administrative appeal procedures for decisions of the 
Administrator under the CO2 Rate-based Trading Program are 
set forth in part 78 of this chapter.


Sec.  62.16431  How will the Clean Energy Incentive Program be 
administered under the federal plan?

    (a)(1) The Administrator will participate in the Clean Energy 
Incentive Program, established under subpart UUUU of part 60 of this 
chapter, on behalf of any state for whom this subpart is promulgated as 
a federal plan under section 111(d) of the Act. The Administrator will 
award, on behalf of each such state, early action ERCs for generation 
and savings achieved in 2020 and/or 2021 that result from the

[[Page 65093]]

following types of eligible renewable energy (RE) and demand-side 
energy efficiency (EE) projects:
    (i) Metered wind power;
    (ii) Metered solar power; and
    (iii) Demand-side EE implemented in a low-income community.
    (2) Eligible RE projects must commence construction, and eligible 
demand-side EE projects must commence implementation, after September 
6, 2018 for those states on whose behalf the EPA is implementing the 
federal plan. Eligible projects must be located in or benefit the state 
on whose behalf the EPA is implementing the federal plan.
    (b) Early action ERCs will be distributed pursuant to a process to 
be prescribed by the Administrator, and in a manner to be demonstrated 
by the Administrator to have no impact on the aggregate emission 
performance of affected EGUs required to meet rate-based emission 
standards during the compliance periods.
    (c) The Administrator will match these early action ERCs with 
additional matching ERCs pursuant to a process to be prescribed by the 
Administrator. Matching awards will be made up to a limit equivalent to 
the state's pro rata share of 300 million short tons of CO2 
emissions.
    (d) The awards, including the matching award, will be executed as 
follows:
    (1) For RE projects that generate metered MWh from wind or solar 
resources: For every two MWh generated, the project will receive one 
early action ERC under paragraph (b) of this section and one matching 
ERC from the match under paragraph (c) of this section; and
    (2) For EE projects that benefit low-income communities as 
determined by the Administrator solely for purposes of this subpart: 
For every two MWh in end-use demand savings achieved, the project will 
receive two early action ERCs under paragraph (b) of this section and 
two matching ERCs from the match under paragraph (c) of this section.

Emission Rate Credit Issuance, Adjustment, and Revocation


Sec.  62.16434  What affected EGUs qualify for generation of ERCs?

    (a) ERCs may only be issued to affected EGUs under the conditions 
listed in paragraphs (b) and (c) of this section.
    (b) For affected EGUs that emit below their applicable emission 
standard, the amount of ERCs generated must be calculated using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TP23OC15.019


Where:

ERCs = Number of emission rate credits generated by an affected EGU 
during an applicable compliance period (MWh).
EGU emission standard = The emission standard the affected EGU must 
comply with during the applicable compliance period according to 
Sec.  62.16420 (lb/MWh).
EGU emission rate = The affected EGU's measured CO2 
emission rate measured in accordance with Sec.  62.16540 (lb/MWh).
EGU generation = Total net energy output generation of the affected 
EGU during the applicable compliance period measured in accordance 
with Sec.  62.16540 (MWh).

    (c) Stationary combustion turbines that meet the definition of an 
affected EGU may generate net energy output MWh gas shift ERCs (GS-
ERCs) for all hours of operation during a given compliance period 
according to paragraphs (c)(1) through (3) of this section.
    (1) To calculate the number of GS-ERCs:

    GS-ERCs = EGU Generation * Incremental Generation Factor * GS-ERC 
Emission Factor

Where:

GS-ERC = Net energy output MWh gas shift ERCs.
EGU generation = Total net energy output generation of the affected 
EGU during the applicable compliance period measured in accordance 
with Sec.  62.16540 (MWh).
Incremental Generation Factor = See Table 2 of this subpart for the 
applicable factor for each compliance period.
GS-ERC Emission Factor = Value calculated using equation (c)(2) of 
this section.

    (2) To calculate the GS-ERC Emission factor for your specific 
affected EGU you must use the following equation:
[GRAPHIC] [TIFF OMITTED] TP23OC15.020


Where:

GS-ERC Emission Factor = Factor to be used in the equation in 
paragraph (c)(1) of this section for GS-ERC calculation.
EGU emission rate = Affected EGU's measured CO2 emission 
rate measured in accordance with Sec.  62.16540 (lb/MWh).
Steam turbine emission standard = Steam turbine emission standard 
for the corresponding compliance period as found in Table 1 of this 
subpart (lb/MWh).

    (3) Notwithstanding any other provision of this subpart, GS-ERCs 
must not be used for compliance by an affected EGU that is a stationary 
combustion turbine. Stationary combustion turbines may use other ERCs 
in their compliance demonstration.


Sec.  62.16435  What eligible resources qualify for generation of ERCs 
in addition to affected EGUs?

    (a) ERCs may only be issued to an eligible resource that meet each 
of the requirements in paragraphs (a)(1) through (4) of this section. 
All categories of resources other than on-shore utility scale wind, 
utility scale solar photovoltaics, concentrated solar power, geothermal 
power, nuclear energy, or utility scale hydropower, and all provisions 
of this subpart relating to such resources, are not available or 
applicable in States where this subpart has been promulgated as a 
federal plan pursuant to section 111(d)(2) of the Act.
    (1) Resources qualifying for eligibility only include resources 
which increased new installed electrical generation nameplate capacity, 
or new electrical savings measures installed or implemented after 
January 1, 2013. If a resource had a nameplate capacity uprate, then 
ERCs may be issued only for the difference in generation between the 
uprated nameplate capacity and its nameplate capacity prior to the 
uprate. ERCs must not be issued for generation for an uprate that 
followed a derate that occurred on or after January 1, 2013. A resource 
that is relicensed or receives a license extension is considered 
existing

[[Page 65094]]

capacity and is not an eligible resource, unless it receives a capacity 
uprate as a result of the relicensing process that is reflected in its 
relicensed permit. In such a case, only the difference in nameplate 
capacity between its relicensed permit and its prior permit is eligible 
to be issued ERCs.
    (2) The resource must be connected to, and delivers energy to or 
saves electricity, on the electric grid in the contiguous United 
States.
    (3) The resource is located in a State whose affected EGUs are 
subject to rate-based emission standards pursuant to this regulation, 
unless the resource is located in a State with mass-based emission 
standards and the resource can demonstrate (e.g., through a power 
purchase agreement or contract for delivery) transmission of its 
generation into a State whose affected EGUs are subject to rate-based 
emission standards pursuant to this regulation.
    (4) The resource falls into one of the following categories of 
resources:
    (i) Renewable electric generating technologies using one of the 
following renewable energy resources: wind, solar, geothermal, hydro, 
wave, tidal;
    (ii) Qualified biomass;
    (iii) Waste-to-energy (biogenic portion);
    (iv) Nuclear energy;
    (v) A non-affected combined heat and power unit, including waste 
heat power; or
    (vi) A demand-side EE or demand-side management measure that saves 
electricity and is calculated on the basis of quantified ex poste 
savings, not ``projected'' or ``claimed'' savings.
    (b) Any resource that does not meet the requirements of this 
subpart cannot generate ERCs for use in the compliance demonstration 
required under Sec.  62.16420.
    (c) ERCs may not be issued to any of the following:
    (1) New, modified, or reconstructed EGUs that are subject to 
subpart TTTT of part 60 of this chapter, except CHP units that meet the 
requirements of a CHP unit under paragraph (a) of this section;
    (2) EGUs that do not meet the applicability requirements of Sec.  
62.16410, except CHP units that meet the requirements of a CHP unit 
under paragraph (a) of this section;
    (3) Measures that reduce CO2 emissions outside the 
electric power sector, including GHG offset projects representing 
emission reductions that occur in the forestry and agriculture sectors, 
direct air capture, and crediting of CO2 emission reductions 
that occur in the transportation sector as a result of vehicle 
electrification; and
    (4) Any measure not approved by the EPA to generate ERCs in 
connection with a specific State plan.


Sec.  62.16440  What is the process for revocation of qualification 
status of an eligible resource?

    (a) If an eligible resource is found to not meet the requirements 
of Sec.  62.16435 in the Rate-based Trading Program, then the 
Administrator will revoke the eligibility of the eligible resource to 
be issued ERCs. In addition, the provisions of Sec.  62.16450(d) may 
apply.
    (b) Any instance of intentional misrepresentation in an eligibility 
application or monitoring and verification (M&V) report may be cause 
for revocation of the qualification status of an eligible resource.
    (c) Repeated instances of error or misstatement of MWh of 
electricity generation or savings in submitted M&V reports, or in any 
other submissions may be cause for the Administrator to revoke the 
eligibility of an eligible resource to be issued ERCs.
    (d) In the event of an intentional misrepresentation, or repeated 
instances of error or misstatement, in program submissions, by the 
authorized account representative of the eligible resource, the 
Administrator may prohibit the eligible resource from any further 
eligibility to be issued ERCs. In addition, the provisions of Sec.  
62.16450 (a) through (d) may apply.


Sec.  62.16445  What is the process for the issuance of ERCs?

    The process and requirements for issuance of ERCs for affected EGUs

at a minimum, aggregated information about the location of measures 
that constitute an eligible resource, provided that the accredited 
independent verifier and the Administrator have the ability to access 
information specifying the location of each discrete measure that 
constitutes an eligible resource.
    (3) Demonstration that the eligible resource meets all applicable 
eligibility requirements in Sec.  62.1435.
    (4) A certification that the eligibility application has only been

pursuant to the authority in their individual State plans.
    (5) An evaluation measurement and verification (EM&V) plan.
    (6) A verification report from an accredited independent verifier 
who meets the requirements of Sec. Sec.  62.16470 and 62.16475.
    (7) An authorization that provides for the following: The 
Administrator may inspect (including a physical inspection of the 
eligible resource and its meter) and/or audit the eligible resource at 
any time and verify that the eligible resource and the EM&V plan have 
been implemented as described in the eligibility application.
    (8) The following statement, signed by the designated 
representative of the eligible resource:
    (i) ``I certify under penalty of law that I have personally 
examined, and am familiar with, the statements and information 
submitted in this document and all its attachments. Based on my 
personal knowledge and/or inquiry of those individuals with primary 
responsibility for obtaining the information, I certify that the 
statements and information are to the best of my knowledge and belief 
true, accurate, and complete. I am aware that there are significant 
penalties for submitting false statements and information or omitting 
required statements and information, including the possibility of fine 
or imprisonment.''
    (ii) [Reserved]
    (9) Any other information required by the Administrator.
    (b) Registration of eligible resources. The Administrator must 
review the eligibility application to determine whether the affected 
EGU or eligible resource meets the requirements of Sec.  paragraph (a) 
of this section, and if it determines that the requirements are met, 
approve the eligibility application and register the affected EGU or 
eligible resource in an ERC tracking system that meets the requirements 
of Sec.  62.16515. Once so registered, the affected EGU or eligible 
resource is eligible to be issued ERCs, provided all other applicable 
requirements continue to be met.
    (c) M&V reports. For an eligible resource, the designated 
representative must submit to the Administrator an M&V report prior to 
issuance of ERCs by the Administrator.
    (d) Verification reports. For an eligible resource, the authorized 
account representative must submit a verification report from an 
accredited independent verifier that meets the requirements of 
Sec. Sec.  62.16470 and 62.16475 as part of each eligibility 
application and M&V report. While considered a part of the eligibility 
application and M&V report, the verification report must be submitted 
separately by the accredited independent verifier to the Administrator.
    (e) Issuance of ERCs. ERCs may only be issued by the Administrator 
based on actual electricity generation or savings documented in an M&V 
report that meets the requirements of Sec.  62.16460 and a verification 
report that meets the requirements of Sec.  62.16465. Only one ERC will 
be issued for each verified MWh.
    (f) Tracking system. ERCs may only be issued through an ERC 
tracking system that meets the requirements of Sec.  62.16515.


Sec.  62.16450  What is the process for error adjustments or 
misstatement, and suspension of ERC issuance?

    (a) In the event of error or misstatement of quantified MWh of 
electricity generation or savings in a previous M&V report for which 
ERCs have been issued, the Administrator may adjust the number of ERCs 
issued in a subsequent reporting period to address the error or 
misstatement, by subtracting a number of MWh from the quantified and 
verified MWh in the M&V report for the subsequent reporting period. In 
the event that an error or inadvertent misstatement occurs in a final 
M&V report for an eligible resource, for which ERCs have been issued, 
the provisions of paragraph (b) of this section will apply.
    (b) In the event of error or misstatement of quantified MWh of 
electricity generation or savings in the final M&V report for an 
eligible resource, for which ERCs have been issued, the Administrator 
will revoke ERCs from the general account held by the authorized 
account representative of the eligible resource, in an amount necessary 
to correct the error or misstatement. In the event that the general 
account of the eligible resource holds an insufficient number of ERCs 
to correct the error or misstatement, the authorized account 
representative must submit to the Administrator within 30 days a number 
of ERCs necessary to correct the error or misstatement. Failure to meet 
this requirement will

[[Page 65096]]

result in prohibition of the authorized account representative for the 
eligible resource from further participation in the program, unless 
reauthorized at the discretion of the Administrator.
    (c) The Administrator may freeze the general account held by an 
authorized account representative of an eligible resource at any time, 
for cause, if the Administrator determines ERCs have been improperly 
issued, based on a misrepresentation or misstatement in an eligibility 
application or M&V report. The Administrator may also freeze the 
general account of an authorized account representative of an eligible 
resource pending investigation of potential misrepresentation, error, 
or misstatement in an eligibility application of an eligible resource, 
or in an M&V report for which ERCs have been issued. Freezing a general 
account will prevent transfer of ERCs out of the account.
    (d) If ERCs are issued for an eligible resource that is found to be 
ineligible, then the Administrator may take the actions in paragraphs 
(d)(1) through (3) of this section.
    (1) Freeze the general account for the eligible resource, 
preventing any transfers of ERCs out of the account.
    (2) Revoke and deduct ERCs held in the general account of the 
authorized account representative for an eligible resource, in a number 
equal to the number of ERCs issued for the ineligible eligible 
resource.
    (3) In the event that the general account of the eligible resource 
holds a number of ERCs less than the number of ERCs issued for the 
ineligible eligible resource, the delegated representative of an 
eligible resource must submit to the Administrator within 30 days a 
number of ERCs necessary to fully account for all ERCs issued for the 
ineligible eligible resource. Failure to meet this requirement will 
result in prohibition of the eligible resource from further 
participation in the program, unless reauthorized at the discretion of 
the Administrator.
    (e) The Administrator may temporarily or permanently suspend 
issuance of ERCs for an eligible resource, for the following reasons in 
paragraphs (e)(1) through (3) of this section.
    (1) Pending investigation of potential misrepresentation, error, or 
misstatement in an M&V report, for which ERCs have been issued, or the 
eligibility status of an eligible resource.
    (2) In the case of repeated error or misstatements in submitted M&V 
reports.
    (3) In the case of an intentional misrepresentation in a submitted 
M&V report.

Evaluation Measurement and Verification Plans, Monitoring and 
Verification Reports, and Verification


Sec.  62.16455  What are the requirements for evaluation measurement 
and verification plans for eligible resources?

    (a) EM&V plan requirements. Any EM&V plan submitted in support of 
the issuance of an ERC pursuant to this rule must meet the requirements 
of this section.
    (b) General EM&V plan criteria. Each EM&V plan must identify the 
eligible resource and its approved eligibility application.
    (c) Specific EM&V plan criteria. Each EM&V plan must provide the 
manner in which the electricity generated or saved by the eligible 
resource will be quantified, monitored and verified, and the manner of 
quantification, monitoring and verification must meet the criteria 
listed in paragraphs (c)(1) through (7) of this section, as applicable 
to the specific eligible resource.
    (1) For a nuclear energy resource or a renewable energy resource 
with a nameplate capacity of 10 kW or more and for a renewable energy 
resource with a nameplate capacity of less than 10 kW for which metered 
data are available, each EM&V plan must specify that the requirements 
in paragraphs (c)(1)(i) through (vi) of this section are met.
    (i) The generation data are physically measured on a continuous 
basis using a revenue-quality meter, which means a meter used by a 
control area operator for financial settlements, or a meter that meets 
the American National Standards Institute No. C12.20., Code for 
Electricity Metering, metering accuracy standards, or a meter that 
meets an alternative equivalent standard that has been approved in 
advance of its use to measure generation pursuant to this regulation by 
the EPA.
    (ii) The generating data are measured at the generator's bus bar, 
or, for a renewable energy resource with a nameplate capacity of less 
than 10 kW that is interconnected behind an individual business or 
household meter, the generating data were measured at the AC output of 
the inverter and adjusted to reflect the only energy delivered into 
either the transmission or distribution grid at the generator bus bar 
and not any energy used on-site at the generator.
    (iii) The generation data from only one eligible resource 
generating unit may be associated with each meter, and generation data 
may not be aggregated, unless all the following provisions are met:
    (A) All of the generating units have the same essential generation 
characteristics;
    (B) All of the generating units are located in the same State;
    (C) The nameplate capacity of the individual units being aggregated 
is each less than 150 kW, and units collectively do not exceed a total 
nameplate capacity of 1 MW when aggregated, or alternative requirements 
approved by the EPA in connection with the specific State plan pursuant 
to which that EM&V plan or M&V report is submitted; and
    (D) The generation data are measured by the same type of meter that 
is subject to the same maintenance and quality assurance procedures.
    (iv) The generation data are collected electronically and 
telemetered from the generator to its control area operator and 
verified through a control area energy accounting or settlement process 
which occurs at least monthly, unless the generation unit does not go 
through a control area operator, in which case the generation data must 
be collected by manual meter readings conducted by an independent 
verifier that is either not affiliated with the owner or operator of 
the qualifying renewable energy generating resource or is precluded 
pursuant to the relevant State plan from the ability to transfer or 
retire ERCs issued to that qualifying renewable energy generating 
resource or, if the generating unit is less than 10 kw and does not 
generate enough electricity to enable monthly reporting, then the data 
may be self-reported and reported no less than annually.
    (v) The generation data serve a load that otherwise would have been 
served by the grid if not for the generator. Specifically:
    (A) ERCs shall not be issued for energy generation used to supply 
the ancillary equipment used to operate a generating station or 
substation (``station service'') or parasitic load on the generator's 
side of the point of interconnection; and
    (B) For generators interconnected to transmission systems and with 
on-site loads other than station service drawing generation before the 
metering point, ERCs may be issued for on-site load, if the owner or 
operator of the eligible resource can demonstrate that the metering 
used is capable of distinguishing between on-site load and station 
service.
    (vi) Any other requirements approved by the EPA in connection with 
the specific State plan pursuant to which that EM&V plan is submitted.

[[Page 65097]]

    (2) For a renewable energy resource with a nameplate capacity of 
less than 10 kW and that does not have a meter, each EM&V plan must 
require that the following requirements in paragraphs (c)(2)(i) though 
(vii) of this section are met.
    (i) Metered data are unavailable.
    (ii) At least 1 MW of net energy output is generated to the 
distribution or transmission system over a continuous 365-day period.
    (iii) The generation data may not be aggregated, unless the 
following provisions are met:
    (A) All of the generating units have the same essential generation 
characteristics;
    (B) All of the generating units are located in the same State;
    (C) The nameplate capacity of the individual units being aggregated 
is each less than 150 kW, and units collectively do not exceed a total 
nameplate capacity of 1 MW when aggregated, or alternative requirements 
approved by the EPA in connection with the specific State plan pursuant 
to which that EM&V plan or M&V report is submitted; and
    (D) The generation data are measured by the same generation 
estimating software or algorithms.
    (iv) The generation data are measured on at least a monthly basis 
using generation estimating software or algorithms that are based on an 
on-site inspection prior to interconnection and a resource study (wind, 
shading, solar irradiance, depending on the resource), or engineering 
information that takes into account the capacity, age, and type of 
qualifying energy generating resource, and all input parameters and 
assumptions must be clearly delineated, or if the generating unit does 
not generate enough electricity to enable monthly reporting, then the 
data may be reported no less than annually.
    (v) The generation data are self-reported to the distribution 
utility through an electronic internet-based portal with software that 
reports total and hourly generation.
    (vi) The generation data serve a load that otherwise would have 
been served by the grid if not for the generator. The ERC is only based 
on generation transferred from the eligible resource to the 
transmission or distribution grid, and is not based on the generation 
used on-site by the customer.
    (vii) Any other requirements approved by the EPA in connection with 
the specific State plan pursuant to which that EM&V plan is submitted.
    (3) For qualified biomass feedstocks used, in addition to the 
requirements of paragraphs (c)(1) or (2) of this section, whichever 
section is applicable, each EM&V plan must demonstrate that the 
requirements approved by the EPA for that biomass feedstock, and its 
associated biogenic CO2, have been met.
    (4) For a waste-to-energy resource, in addition to the requirements 
of paragraphs (c)(1) or (2) of this section, as applicable, and 
paragraph (c)(3) of this section, each EM&V plan must specify:
    (i) The total net energy generation from the resource in MWh;
    (ii) The method for determining the specific portion of the total 
net energy output from the resource that is related to the biogenic 
portion of the waste materials; and
    (iii) The net energy output measured with the relevant method 
approved by the EPA in connection with the specific State plan pursuant 
to which that EM&V plan is submitted demonstrates that the requirements 
approved by the EPA in connection with that State plan have been met.
    (5) For a combined heat and power unit, in addition to the 
requirements of paragraphs (c)(1) or (2) of this section, as 
applicable, and paragraph (c)(3) of this section, each EM&V plan must 
meet one of the requirements in paragraphs (c)(5)(i) through (iv) of 
this section, as applicable, and any other requirements approved by the 
EPA.
    (i) If the combined heat and power unit has an electric generating 
capacity greater than 25 MW, then the EM&V plan must meet the 
requirements that apply to an affected EGU under Sec.  62.16540.
    (ii) If the combined heat and power unit has an electric generating 
capacity less than or equal to 25 MW and greater than 1 MW, and it uses 
only natural gas and/or distillate fuel oil, then the EM&V plan must 
meet the low mass emission unit CO2 emission monitoring and 
reporting methodology in part 75 of this chapter.
    (iii) If the combined heat and power unit has an electric 
generating capacity less than or equal to 25 MW and greater than 1 MW, 
and it uses anything other than only natural gas and/or distillate fuel 
oil, then the EM&V plan must meet the low mass emission unit 
CO2 emission monitoring and reporting methodology in part 75 
of this chapter.
    (iv) If the combined heat and power unit has an electric generating 
capacity less than or equal to 1 MW the unit must keep monthly 
cumulative recordings of useful thermal output and fossil fuel input 
along with the determination of baseline thermal source efficiencies 
based on manufacturer data. For CHP units that directly serve on-site 
end-use electricity loads, avoided T&D system losses can be assessed as 
is commonly practiced with demand-side EE.
    (6) For demand-side electricity savings that avoid a transmission 
and distribution loss, each EM&V plan must measure the transmission and 
distribution loss based on the lesser of 6 percent of the facility- or 
premises-level electricity savings measured at the electricity 
customer's meter, or the statewide annual average transmission and 
distribution loss rate (expressed as a percentage) from the most recent 
year that is published in the US EIA State Electricity Profile. No 
other transmission and distribution loss factors may be used in 
calculating the electricity savings.
    (7) Each EM&V plan for an EE program, EE project, or EE measure 
must specify how each of the requirements in paragraphs (c)(7)(i) 
through (x) of this section will be met in quantifying the electricity 
savings from that EE program, EE project, or EE measure.
    (i) All electricity savings must be quantified on an ex-post basis, 
which means after the electricity savings have occurred, or on a real-
time basis, which means at the time the electricity savings are 
occurring. Electricity savings must not be quantified on an ex-ante 
basis, which means estimates of MWh savings that are generated prior to 
implementing the subject EE program, EE project, or EE measure, and 
that are not quantified using EM&V methods and procedures.
    (ii) All electricity savings must be quantified and verified based 
on methods and procedures detailed in an industry best-practice EM&V 
protocol or guideline. Each EM&V plan must include a demonstration of 
how the best-practice protocol or guideline was selected and will be 
applied to the specific EE program, EE project, or EE measure covered 
in the EM&V plan, and an explanation of why that particular protocol or 
guideline was selected. Protocols and guidelines are considered to be 
best practice if they:
    (A) Have gone through a rigorous and credible peer review process 
that shows the applicable methods to be valid through empirical 
testing; and
    (B) Have been accepted and approved for use by identifiable state 
regulatory commissions. Examples of such protocols and guidelines that 
may be provided in EM&V guidance issued by the Administrator will be 
acceptable.
    (iii) All electricity savings must be quantified as the difference 
between the observed electricity use and a common practice baseline 
(CPB), which is the equipment that would typically have been 
installed--or that a typical

[[Page 65098]]

consumer or building owner would have continued using--in a given 
circumstance (i.e., a given building type, EE program type or delivery 
mechanism, and geographic region) at the time of EE implementation. 
Examples of CPBs for specific EE programs, EE projects, EE measures, 
and for certain EM&V methods that may be provided in EM&V guidance 
issued by the Administrator will be acceptable. The EM&V plan must 
specify the reason the specific CPB was selected, which must include an 
analysis of the appropriateness of that CPB for the EE program, EE 
project, or EE measure covered in the EM&V plan, based on:
    (A) Characteristics of the EE program, EE project, or EE measure;
    (B) The delivery mechanism used to implement the EE program, EE 
project, or EE measure (e.g., installed as part of a utility EE program 
versus a point-of-sale rebate);
    (C) Local consumer and market characteristics;
    (D) Applicable building energy codes and standards and average 
compliance rates; and
    (E) The method applied: Project-based measurement and verification 
(PB-MV), comparison group approaches, or deemed savings.
    (iv) All electricity savings must be quantified by applying one or 
more of the following methods: Project-based measurement and 
verification (PB-MV), comparison group approaches, or deemed savings.
    (A) If a comparison group approach is used, then the EM&V plan must 
quantify electricity savings by taking the difference between a 
comparison group's electricity use and the electricity use of EE 
program participants. Comparison group approaches may include 
randomized control trials and quasi-experimental methods, as described 
in industry best-practice protocols and guidelines. Examples of such 
protocols and guidelines provided in EM&V guidance that may be issued 
by the Administrator will be acceptable.
    (B) If deemed savings are used, then the EM&V plan must specify 
that the deemed savings values will only be used for the specific EE 
measure for which they were derived. The EM&V plan must also specify 
the name and Web address of the technical reference manual (TRM) in 
which all deemed electricity savings values will be documented. Prior 
to use in an EM&V plan, all TRMs must undergo a review process in which 
the public, stakeholders, and experts are invited--with adequate 
advance notification (via the internet and other social media)--to 
provide comment, have at least 2 months to provide comment, and in 
which all such comments and associated responses are made publicly 
available. All TRMs must also be publicly accessible over the full 
period of time in which they are being used in conjunction with an EM&V 
plan for the purpose of quantifying savings, and must be subsequently 
updated in the same manner at least every 3 years. The TRM must 
indicate, for each subject EE measure, the associated electricity 
savings value, the conditions under which the value can be applied 
(including the climate zone, building type, manner of implementation, 
applicable end uses, operating conditions, and effective useful life), 
and the manner in which the electricity savings value was quantified, 
which must include applicable engineering algorithms, source 
documentation, specific assumptions, and other relevant data to support 
the quantification of savings from the subject EE measure.
    (v) All EE programs, EE projects, or EE measures must be quantified 
at time intervals (in years) sufficient to ensure that MWh savings are 
accurately and reliably quantified. Such time intervals must be 
specified and explained in the EM&V plan. Factors that must be taken 
into consideration when determining the appropriate time interval 
include the characteristics of the specific EE program, EE project, or 
EE measure, expected variability in electricity savings (where greater 
variability necessitates more frequent quantification), the expected 
scale and magnitude of the electricity savings (where greater 
quantities of savings necessitate more frequent quantification), and 
the experience implementing and quantifying savings from the resource 
(where less experience--for example, with new and innovative EE program 
types--necessitates more frequent quantification). The time intervals 
must end no sooner than the last day of the effective useful life of 
the EE program, EE project, or EE measure, and must last no longer 
than:
    (A) Every 4-year intervals for building energy codes and product 
standards;
    (B) Every 1, 2, or 3 years for public or consumer-funded EE 
program, EE project, or EE measure, as relevant for the type of EE 
program, EE project, or EE measure and factors listed in paragraph 
(c)(7)(v) of this section; and
    (C) Annually for commercial and industrial projects, unless the 
resource provider can provide a reasonable justification in the EM&V 
plan for why an annual time interval is not feasible, and can 
additionally explain how the accuracy and reliability of savings values 
will not be lessened.
    (vi) EM&V plans must specify and document how the EM&V components 
in paragraphs (c)(7)(vi)(A) through (E) of this section will be 
analyzed, considered, or otherwise addressed in the quantification and 
verification of electricity savings.
    (A) The effects of changes in independent factors on reported 
electricity savings (i.e., factors that are not directly related to the 
EE measure, such as weather, occupancy, and production levels).
    (B) The effective useful life (EUL) or duration of time the EE 
measure is anticipated to remain in place and operable with the 
potential to save electricity, which must be based on the application 
of EM&V methods, an industry best-practice persistence study, deemed 
estimates of effective useful life, or a combination of all three.
    (1) If deemed estimates of effective useful life are used, then 
they must specify the date by which the EE measure will stop saving 
electricity.
    (2) If industry best-practices persistence studies are used to 
modify an effective-useful-life value, then they must be conducted at 
least every 5 years.
    (C) The potential sources of double counting, and the associated 
steps for avoiding and correcting for it, such as:
    (1) For an EE program or EE project with identified participants, 
track the type and number of EE measures implemented at the utility-
customer level.
    (2) For an EE program or EE project without identified 
participants, such as point-of-sale rebates and retailer or 
manufacturer incentive programs, track applicable vendor, retailer, and 
manufacturer data.
    (3) For EE programs (such as those implemented by a utility) and EE 
projects (such as those implemented by an energy service company) that 
both have identified participants, use tracking data to avoid and 
correct for double counting that may occur across the two; and
    (4) For EE programs with identified participants and those without 
(such as retail incentives to purchase energy-efficient equipment), use 
EE program tracking data for the former and use applicable vendor, 
retailer, and manufacturer data for the latter to avoid and correct for 
double counting that may occur across the two.
    (D) The EE savings verification approaches for ensuring that EE 
measures have been properly installed, are operating as intended, and 
therefore have the potential to save electricity,

[[Page 65099]]

including how verification will be carried out within the first year of 
implementation of the EE program, EE project, or EE measure using best-
practice approaches, such as physical inspections at a customer's 
premises, phone and mail surveys, and reviews of sales receipts and 
other documentation. If such approaches are documented in EM&V guidance 
issued by the Administrator, they will be treated as acceptable.
    (E) The interactive effects of EE programs, EE projects, or EE 
measures on electricity usage, which are increases or decreases in 
electricity usage at an end-use facility or premises that occurs 
outside of specific end-uses(s) targeted by the EE program, EE project, 
or EE measure (e.g., lighting retrofits to improve EE can reduce waste 
heat to the surrounding conditioned space, and therefore may increase 
the required electric heating load in a facility or premises).
    (vii) The EM&V plan must specify how the accuracy and reliability 
of the electricity savings of the EE program, EE project, or EE measure 
will be assessed, and must discuss the rigor of the method selected to 
quantify the electricity savings. It must also discuss the approaches 
that will be used to control all relevant types of bias and to minimize 
the potential for systematic and random error, as well as the program- 
or project-specific circumstances in which such bias and error are 
likely to arise. Approaches to minimizing bias and error are provided 
in the EM&V guidance that may be issued by the Administrator will be 
acceptable.
    (viii) If sampling will be used to quantify the electricity savings 
from an EE program, then the MWh estimates derived from sampling must 
have at least 90 percent confidence intervals whose end points are no 
more than 10 percent of the estimate, and the statistical 
precision of the associated estimates must be specified in the EM&V 
plan.
    (ix) All data sources and key assumptions used to quantify 
electricity savings must be described in the EM&V plan.
    (x) Any additional information necessary to demonstrate that the 
electricity savings were appropriately quantified and verified. 
Approaches to quantifying and verifying savings from several EE program 
and EE project types that are provided in EM&V guidance that may be 
issued by the Administrator will be acceptable.
    (d) You must ensure that any EM&V plan submitted pursuant to this 
subpart includes the following certification:
    (1) ``I certify under penalty of law that I have personally 
examined, and am familiar with, the statements and information 
submitted in this document and all its attachments. Based on my inquiry 
of those individuals with primary responsibility for obtaining the 
information, I certify that the statements and information are to the 
best of my knowledge and belief true, accurate, and complete. I am 
aware that there are significant penalties for submitting false 
statements and information or omitting required statements and 
information, including the possibility of fine or imprisonment.''

Sec.  62.16475 when providing verification services for an authorized 
account representative; and
    (2) The instances specified in Sec.  62.16475(d) are cause for 
revocation of a verifier's accreditation.


Sec.  62.16475  What are the procedures of accredited independent 
verifiers must follow to avoid conflict of interest?

    (a) Accredited independent verifiers must not provide verification 
services for any eligible resource for which it has a conflict of 
interest (COI), which means:
    (1) Accredited independent verifiers must have, or have had, no 
direct or indirect financial interest in, or other financial 
relationships with, an eligible resource, or any prospective eligible 
resource, for which they seek to provide a verification report;
    (2) Accredited independent verifiers must have, or have had, no 
direct or indirect organizational or personal relationships with an 
eligible resource, that would impact their impartiality in assessing 
the validity and accuracy of the information in an eligibility 
application or M&V report;
    (3) Accredited independent verifiers must have, or have had, no 
role in the development and implementation of an eligible resource for 
which an authorized account representative seeks issuance of ERCs, 
beyond the provision of verification services;
    (4) Accredited independent verifiers must not be compensated, 
financially or otherwise, directly or indirectly, on the basis of the 
content of its verification report (including eligibility approval of 
an eligible resource, the quantified and verified MWh in an M&V report, 
ERC issuance, or the number of ERCs issued);
    (5) Accredited independent verifiers must not own, buy, sell, or 
hold ERCs, or other financial derivatives related to ERCs, or have a 
financial relationship with other parties that own, buy, sell, or hold 
ERCs or other related financial derivatives;
    (6) An accredited independent verifier must not be incapable of 
providing an impartial verification report for any other reason; and
    (7) An accredited independent verifier must ensure that the subject 
of any verification report must not have the opportunity to review or 
influence any draft or final verification report before its submittal 
to the Administrator, and the accredited independent verifier must 
share any drafts of its reports with the Administrator at the same time 
as it shares them with the subject of the report.
    (b) A contract with an eligible resource for the provision of 
verification services will not constitute a COI.
    (c) Verification reports must include an attestation by the 
accredited independent verifier that it evaluated and disclosed to the 
Administrator any potential COI related to an eligible resource.
    (d) Prior to engaging for the provision of verification services, 
an accredited independent verifier must demonstrate that it has no COI 
related to the eligible resource, as specified in paragraph (a) of this 
section. If a COI is identified for a person or persons within an 
accredited independent verifier for a specific subject or verification, 
in accordance with paragraphs (e) and (f) of this section, then an 
accredited independent verifier may propose to the Administrator steps 
that will be taken to eliminate the COI which include prohibiting the 
person or persons with the conflict from any involvement in the matter 
subject to the conflict, including verification services, access to 
information related to the verification services, access to any draft 
or final verification reports, any communications with the person(s) 
conducting the verification services. In no instance shall an 
accredited independent verifier engage in verification services for an 
eligible resource without the approval of the Administrator.
    (e) Prior to engaging in verification services and writing a 
verification report, an accredited independent verifier must disclose 
to the Administrator all information necessary for the Administrator to 
evaluate a potential COI (including information concerning its 
ownership, past and current clients, related entities, as well as any 
other facts or circumstances that have the potential to create a COI).
    (f) Accredited verifiers have an ongoing obligation to disclose to 
the Administrator any facts or circumstances that may give rise to a 
COI as defined in paragraph (a) of this section.
    (g) The Administrator may reject a verification report from an 
accredited independent verifier, if the Administrator determines that 
the accredited independent verifier has a COI as defined in paragraph 
(a) of this section. If the Administrator rejects an accredited 
independent verifier report for such reasons, then the eligibility 
application or M&V report submittal shall be deemed incomplete and ERCs 
must not be issued pursuant to it.


Sec.  62.16480  What is the process for the revocation of accreditation 
status for an independent verifier?

    (a) The Administrator may revoke the accreditation of an 
independent verifier at any time for cause, including for the reasons 
specified in paragraphs (a)(1) through (4) of this section.
    (1) Failure to fully disclose any issues that may lead to a COI 
with respect to an eligible resource, or other related entity, in 
accordance with Sec.  62.16475(d) through (f).
    (2) The accredited independent verifier is no longer qualified to 
provide verification services.
    (3) Negligence in the conduct of verification activities, or 
neglect of responsibilities pursuant to the requirements of Sec. Sec.  
62.16465, 62.16470, and 62.16475.
    (4) Intentional misrepresentation of data in a verification report.
    (b) [Reserved]

when the Administrator receives the superseding certificate of 
representation shall be binding on the new alternate designated 
representative, the designated representative, and the owners and 
operators of the affected EGU.
    (c) Changes in owners and operators. (1) In the event an owner or 
operator of an affected EGU is not included in the list of owners and 
operators in the certificate of representation under Sec.  62.16500, 
such owner or operator shall be deemed to be subject to and bound by 
the certificate of representation, the representations, actions, 
inactions, and submissions of the designated representative and any 
alternate designated representative of the affected EGU, and the 
decisions and orders of the Administrator, as if the owner or operator 
were included in such list.
    (2) Within 30 days after any change in the owners and operators of 
affected EGU, including the addition or removal of an owner or 
operator, the designated representative or any alternate designated 
representative must submit a revision to the certificate of 
representation under Sec.  62.16500 amending the list of owners and 
operators to reflect the change.
    (d) Changes in affected EGUs at the source. Within 30 days of any 
change in which affected EGUs are located at a source (including the 
addition or removal of an affected EGU), the designated representative 
or any alternate designated representative must submit a certificate of 
representation under Sec.  62.16500 amending the list of affected EGUs 
to reflect the change.
    (1) If the change is the addition of an affected EGU that operated 
(other than for purposes of testing by the manufacturer before initial 
installation) before being located at the source, then the certificate 
of representation must identify, in a format prescribed by the 
Administrator, the entity from whom the affected EGU was purchased or 
otherwise obtained (including name, address, telephone number, and 
facsimile transmission number (if any)), the date on which the affected 
EGU was purchased or otherwise obtained, and the date on which the 
affected EGU became located at the source.

general account in all matters pertaining to the CO2 Rate-
based Trading Program, notwithstanding any agreement between the 
authorized account representative and such person;
    (B) Any alternate authorized account representative shall be 
authorized, and any representation, action, inaction, or submission by 
any alternate authorized account representative shall be deemed to be a

superseding complete application for a general account under paragraph 
(c)(1) of this section is received by the Administrator.
    (ii) Except as provided in paragraph (c)(4)(i) of this section, no

    (a) Except as provided in paragraph (b) of this section, within 
five business days of receiving an ERC transfer that is correctly 
submitted under Sec.  62.16525,

[[Page 65107]]

the Administrator will record an ERC transfer by moving each ERC from 
the transferor account to the transferee account as specified in the 
transfer.
    (b) An ERC transfer to or from a compliance account that is 
submitted for recordation after the allowance transfer deadline for a 
compliance period and that includes any ERCs allocated for any 
compliance period before such allowance transfer deadline will not be 
recorded until after the Administrator completes the deductions from 
such compliance account under Sec.  62.16535 for the compliance period 
immediately before such allowance transfer deadline.
    (c) Where an ERC transfer is not correctly submitted under Sec.  
62.16525, the Administrator will not record such transfer.

and transferee accounts.
    (e) Within 10 business days of receipt of an ERC transfer that is 
not correctly submitted under Sec.  62.16525, the Administrator will 
notify the authorized account representatives of both accounts subject 
to the transfer of:
    (1) A decision not to record the transfer; and
    (2) The reasons for such non-recordation.


Sec.  62.16535  How will deductions for compliance with a CO2 emission 
standard occur?

    For affected EGUs subject to the emission standards listed in Table 
1 of this subpart, the owner or operator of an affected EGU must 
demonstrate compliance with its CO2 emission standard in 
accordance with Sec.  62.16420(c) and incorporate ERCs as listed in 
paragraphs (a) through (f) of this section.
    (a) Availability for deduction for compliance. ERCs are available 
to be deducted from a compliance account and used for compliance with 
an affected EGU's CO2 emissions standard for a compliance 
period only if the ERCs:
    (1) Were allocated for a year in such compliance period or a prior 
compliance period; and
    (2) Are held in the affected EGU's compliance account as of the 
allowance transfer deadline for such compliance period.
    (b) Deductions for compliance. After the recordation, in accordance 
with Sec.  62.16530, of ERC transfers submitted by the ERC transfer 
deadline for a compliance period, the Administrator will deduct from 
each affected EGU's compliance account ERCs available under paragraph 
(a) of this section in order to determine whether the affected EGU 
meets the CO2 emission standard for such compliance period, 
as follows:
    (1) Until the amount of ERCs deducted and subsequently added to the 
total MWh generated by the affected EGU adjusts the affected EGU's 
CO2 emission rate to equal the CO2 emission 
standard for such compliance period; or
    (2) If there are insufficient ERCs to complete the deductions in 
paragraph (b)(1) of this section, until no more ERCs available under 
paragraph (a) of this section remain in the compliance account.
    (c) Identification of ERCs by serial number. The authorized account 
representative for an affected EGU's compliance account may request 
that specific ERCs, identified by serial number, in the compliance 
account be deducted for emissions or excess emissions for a compliance 
period in accordance with paragraph (b) or (e) of this section. In 
order to be complete, such request must be submitted to the 
Administrator by the ERC transfer deadline for such compliance period 
and include, in a format prescribed by the Administrator, the 
identification of the affected EGU and the appropriate serial numbers.
    (d) First-in, first-out. The Administrator will deduct ERCs under 
paragraph (b) or (e) of this section from the affected EGU's compliance 
account in accordance with a complete request under paragraph (c)(1) of 
this section or, in the absence of such request or in the case of 
identification of an insufficient amount of ERCs in such request, on a 
first-in, first-out accounting basis.
    (e) Deductions for exceeding the emission standard. After making 
the deductions for compliance under paragraph (b) of this section for a 
compliance period in a year in which the affected EGU has exceeded its 
CO2 emission standard, the Administrator will deduct from 
the affected EGU's compliance account an amount of ERCs, allocated for 
a compliance period in a prior year or the compliance period in the 
year of the excess emissions or in the immediately following year, 
equal to two times the number of ERCs of the affected EGU's excess 
emissions.
    (f) Recordation of deductions. The Administrator will record in the 
appropriate compliance account all deductions from such an account 
under paragraphs (b) and (e) of this section.


Sec.  62.16540  What monitoring requirements must I comply with?

    (a) You must follow the requirements described in paragraphs (a)(1) 
through (8) of this section to monitor emissions and net energy output 
at your affected EGU.
    (1) The owner of operator of an affected EGU required to meet an 
emission standard must prepare a monitoring plan in accordance with the 
applicable provisions in Sec.  75.53(g) and (h) of this chapter, unless 
such a plan is already in place under another program that requires 
CO2 mass emissions to be monitored and reported according to 
part 75 of this chapter.
    (2) Each compliance period shall include only ``valid operating 
hours'' in the compliance period, i.e., operating hours for which:
    (i) ``Valid data'' (as defined in Sec.  62.16570) are obtained for 
all of the parameters used to determine the hourly CO2 mass 
emissions (lbs). For the purposes of this subpart, substitute data 
recorded under part 75 of this chapter are not considered to be valid 
data; and
    (ii) The corresponding hourly net energy output value is also valid 
data (Note: for hours with no useful output, zero is considered to be a 
valid value).
    (3) The owner or operator of an affected EGU must measure and 
report the hourly CO2 mass emissions (lbs) from each 
affected unit using the procedures in paragraphs (a)(3)(i) through 
(vii) of this section, except as provided in paragraph (a)(4) of this 
section.
    (i) The owner or operator of an affected EGU must install, certify, 
operate, maintain, and calibrate a CO2 continuous emissions 
monitoring system (CEMS) to directly measure and record CO2 
concentrations in the affected EGU exhaust gases emitted to the 
atmosphere and an exhaust gas flow rate monitoring system according to 
Sec.  75.10(a)(3)(i) of this chapter. As an alternative to direct 
measurement of CO2 concentration, the owner or operator of 
an affected EGU may use data from a certified oxygen (O2) 
monitor to calculate hourly average CO2 concentrations, in 
accordance with Sec.  75.10(a)(3)(iii) of this chapter. If 
CO2 concentration is measured on a dry basis, then you must 
also install, certify, operate, maintain, and calibrate a continuous 
moisture monitoring system, according to Sec.  75.11(b) of this 
chapter. Alternatively, you may either use an appropriate fuel-specific 
default moisture value from Sec.  75.11(b) or submit a petition to the 
Administrator under Sec.  75.66 of this chapter for a site-specific 
default moisture value.

[[Page 65108]]

    (ii) For each ``valid operating hour'', calculate the hourly 
CO2 mass emission rate (tons/hr), either from Equation F-11 
in Appendix F to part 75 of this chapter (if CO2 
concentration is measured on a wet basis), or by following the 
procedure in section 4.2 of Appendix F to part 75 of this chapter (if 
CO2 concentration is measured on a dry basis).
    (iii) Next, multiply each hourly CO2 mass emission rate 
by the affected EGU or stack operating time in hours (as defined in 
Sec.  72.2 of this chapter), to convert it to tons of CO2. 
Multiply the result by 2000 lb/ton to convert it to lb.
    (iv) The hourly CO2 tons/hr values and affected EGU (or 
stack) operating times used to calculate CO2 mass emissions 
are required to be recorded under Sec.  75.57(e) of this chapter and 
must be reported electronically under Sec.  75.64(a)(6). You must use 
these data to calculate the hourly CO2 mass emissions.
    (v) Sum all of the hourly CO2 mass emissions values that 
were calculated according to procedures specified in paragraph 
(a)(3)(ii) of this section over the entire compliance period.
    (vi) For each continuous monitoring system used to determine the 
CO2 mass emissions from an affected EGU, the monitoring 
system must meet the applicable certification and quality assurance 
procedures in Sec.  75.20 of this chapter and Appendices A and B to 
part 75 of this chapter.
    (vii) The owner operator of an affected EGU must use only 
unadjusted exhaust gas volumetric flow rates to determine the hourly 
CO2 mass emissions from the affected EGU; the owner or 
operator of an affected EGU must not apply the bias adjustment factors 
described in section 7.6.5 of Appendix A to part 75 of this chapter to 
the exhaust gas flow rate data.
    (4) The owner or operator of an affected EGU that exclusively 
combusts liquid fuel and/or gaseous fuel may, as an alternative to 
complying with paragraph (a)(3) of this section, determine the hourly 
CO2 mass emissions according to paragraphs (a)(4)(i) through 
(vi) of this section.
    (i) Implement the applicable procedures in appendix D to part 75 of 
this chapter to determine hourly affected EGU heat input rates (MMBtu/
h), based on hourly measurements of fuel flow rate and periodic 
determinations of the gross calorific value (GCV) of each fuel 
combusted.
    (ii) For each measured hourly heat input rate, use Equation G-4 in 
Appendix G to part 75 of this chapter to calculate the hourly 
CO2 mass emission rate (tons/hr).
    (iii) For each valid operating hour (as defined in paragraph (a)(2) 
of this section, determine the hourly CO2 mass emission rate 
(tons/hr) using the procedures specified in paragraph (a)(4)(ii) of 
this section and multiply it by the affected EGU or stack operating 
time in hours (as defined in Sec.  72.2 of this chapter), to convert to 
tons of CO2. Then, multiply the result by 2000 lb/ton to 
convert to lb.
    (iv) The hourly CO2 tons/hr values and affected EGU (or 
stack) operating times used to calculate CO2 mass emissions 
are required to be recorded under Sec.  75.57(e) of this chapter and 
must be reported electronically under Sec.  75.64(a)(6). You must use 
these data to calculate the hourly CO2 mass emissions.
    (v) Sum all of the hourly CO2 mass emissions values that 
were calculated according to procedures specified in paragraph 
(a)(4)(iii) of this section over the entire compliance period.
    (vi) The owner or operator of an affected EGU may determine site-
specific carbon-based F-factors (Fc) using Equation F-7b in 
section 3.3.6 of appendix F to part 75 of this chapter, and may use 
these Fc values in the emissions calculations instead of 
using the default Fc values in the Equation G-4 
nomenclature.
    (5) The owner or operator of an affected EGU must install, 
calibrate, maintain, and operate a sufficient number of watt meters to 
continuously measure and record on an hourly basis net electric output. 
Measurements must be performed using 0.2 accuracy class electricity 
metering instrumentation and calibration procedures as specified under 
ANSI Standards No. C12.20. Further, the owner or operator of an 
affected EGU that is a combined heat and power facility must install, 
calibrate, maintain and operate equipment to continuously measure and 
record on an hourly basis useful thermal output and, if applicable, 
mechanical output, which are used with net electric output to determine 
net energy output. The owner or operator must calculate net energy 
output according to paragraph (a)(5)(i) of this section.
    (i) For each valid operating hour of a compliance period that was 
used in paragraph (a)(3) or (4) of this section to calculate the total 
CO2 mass emissions, you must determine Pnet (the 
corresponding hourly net energy output in MWh) according to the 
procedures in paragraphs (a)(5)(i)(A) and (B) of this section, as 
appropriate for the type of affected EGU(s). For an operating hour in 
which a valid CO2 mass emissions value is determined 
according to paragraph (a)(3) or (4) of this section, if there is no 
gross or net electrical output, but there is mechanical or useful 
thermal output, then you must still determine the net energy output for 
that hour. In addition, for an operating hour in which a valid 
CO2 mass emissions value is determined according to 
paragraph (a)(3) or (4) of this section, but there is no (i.e., zero) 
gross electrical, mechanical, or useful thermal output, you must use 
that hour in the compliance determination. For hours or partial hours 
where the gross electric output is equal to or less than the auxiliary 
loads, net electric output shall be counted as zero for this 
calculation.
    (A) Calculate Pnet for your affected EGU using the 
following equation. All terms in the equation must be expressed in 
units of megawatt-hours (MWh). To convert each hourly net energy output 
value reported under part 75 of this chapter to MWh, multiply by the 
corresponding EGU or stack operating time.

Where:

Pnet = Net energy output of your affected EGU for each 
valid operating hour (as defined in paragraph (a)(2) of this 
section) in MWh.

output (if any) of steam turbines in MWh.
(Pe)CT = Electric energy output plus mechanical energy 
output (if any) of stationary combustion turbine(s) in MWh.
(Pe)IE = Electric energy output plus mechanical energy 
output (if any) of your affected EGU's integrated equipment that 
provides electricity or mechanical energy to the affected EGU or 
auxiliary equipment in MWh.
(Pe)A = Electric energy used for any auxiliary loads in 
MWh.
(Pt)PS = Useful thermal output of steam (measured 
relative to SATP conditions as defined in Sec.  62.16570, as 
applicable) that is used for applications that do not

[[Page 65109]]

generate additional electricity, produce mechanical energy output, 
or enhance the performance of the affected EGU. This is calculated 
using the equation specified in paragraph (a)(5)(i)(B) of this 
section in MWh.
(Pt)HR = Non steam useful thermal output (measured 
relative to SATP conditions as defined in Sec.  62.16570, as 
applicable) from heat recovery that is used for applications other 
than steam generation or performance enhancement of the affected EGU 
in MWh.
(Pt)IE = Useful thermal output (relative to SATP 
conditions, as applicable as defined in Sec.  62.16570) from any 
integrated equipment is used for applications that do not generate 
additional steam, electricity, produce mechanical energy output, or 
enhance the performance of the affected EGU in MWh.
TDF = Electric Transmission and Distribution Factor of 0.95 for a 
combined heat and power affected EGU where at least on an annual 
basis 20.0 percent of the total net energy output consists of 
electric or direct mechanical output and 20.0 percent of the total 
net energy output consists of useful thermal output on a 12-
operating month rolling average basis, or 1.0 for all other affected 
EGUs.

    (B) If applicable to your affected EGU (for example, for combined 
heat and power), then you must calculate (Pt)PS using the 
following equation:
[GRAPHIC] [TIFF OMITTED] TP23OC15.015


Where:

(Pt)ps = Useful thermal output of steam (measured 
relative to SATP conditions as defined in Sec.  62.16570, as 
applicable) that is used for applications that do not generate 
additional electricity, produce mechanical energy output, or enhance 
the performance of the affected EGU.
Qm = Measured steam flow in kilograms (kg) (or pounds 
(lb)) for the operating hour.
H = Enthalpy of the steam at measured temperature and pressure 
(relative to SATP conditions as defined in Sec.  62.16570 or the 
energy in the condensate return line, as applicable) in Joules per 
kilogram (J/kg) (or Btu/lb).
CF = Conversion factor of 3.6 x 10 \9\ J/MWh or 3.413 x 10 \6\ Btu/
MWh.

    (C) Sum all of the values of Pnet over the entire 
compliance period. Then, divide the total CO2 mass emissions 
from paragraph (a)(3)(v) or (a)(4)(v) of this section, as applicable, 
by the sum of the Pnet values to determine the 
CO2 emission rate (lb/net MWh) for the compliance period.
    (ii) [Reserved]
    (6) In accordance with Sec.  60.13(g) of this chapter, if two or 
more affected EGUs implementing the continuous emissions monitoring 
provisions in paragraph (a)(2) of this section share a common exhaust 
gas stack and are subject to the same emission standard, then the owner 
or operator may monitor the hourly CO2 mass emissions at the 
common stack in lieu of monitoring each EGU separately. If an owner or 
operator of an affected EGU chooses this option, then the hourly net 
electric output for the common stack must be the sum of the hourly net 
electric output of the individual affected EGUs and the operating time 
must be expressed as ``stack operating hours'' (as defined in Sec.  
72.2 of this chapter).
    (7) In accordance with Sec.  60.13(g) of this chapter, if the 
exhaust gases from an affected EGU implementing the continuous 
emissions monitoring provisions in paragraph (a)(3)(i) of this section 
are emitted to the atmosphere through multiple stacks (or if the 
exhaust gases are routed to a common stack through multiple ducts and 
you elect to monitor in the ducts), then the hourly CO2 mass 
emissions and the ``stack operating time'' (as defined in Sec.  72.2 of 
this chapter) at each stack or duct must be monitored separately. In 
this case, the owner or operator of an affected EGU must determine 
compliance with an applicable emission standard by summing the 
CO2 mass emissions measured at the individual stacks or 
ducts and dividing by the net energy output for the affected EGU.
    (8) If two or more affected EGUs serve a common electric generator, 
then you must apportion the combined hourly net energy output to the 
individual affected EGUs according to the fraction of the total steam 
load contributed by each EGU. Alternatively, if the affected EGUs are 
identical, then you may apportion the combined hourly net electrical 
load to the individual EGUs according to the fraction of the total heat 
input contributed by each EGU.
    (b) [Reserved]


Sec.  62.16545  May I bank CO2 ERCs for future use or transfer?

    (a) An ERC may be banked for future use or transfer in a compliance 
account or a general account in accordance with paragraph (b) of this 
section.
    (b) Any ERC that is held in a compliance account or a general 
account will remain in such account unless and until the ERC is 
deducted or transferred under Sec. Sec.  62.16530, 62.16535, 62.16550, 
or 62.16565.


Sec.  62.16550  How does the Administrator process account errors?

    The Administrator may, at his or her sole discretion and on his or 
her own motion, correct any error in any ATCS account. Within 10 
business days of making such correction, the Administrator will notify 
the authorized account representative for the account.
