40 CFR Part 62

[EPA-HQ-OAR-2019-0338; FRL-9998-62-OAR]
RIN 2060-AU52


Federal Plan Requirements for Municipal Solid Waste Landfills 
That Commenced Construction On or Before July 17, 2014, and Have Not 
Been Modified or Reconstructed Since July 17, 2014

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: In this action, the U.S. Environmental Protection Agency (EPA) 
proposes a federal plan to implement the Emission Guidelines and 
Compliance Times for Municipal Solid Waste Landfills (2016 MSW 
Landfills EG) for existing MSW landfills located in states and Indian 
country where state plans or tribal plans are not in effect. This 
proposed MSW Landfills Federal Plan includes the same elements as 
required for a state plan: Identification of legal authority and 
mechanisms for implementation; inventory of designated facilities; 
emissions inventory; emission limits; compliance schedules; a process 
for the EPA or state review of design plans for site-specific gas 
collection and control systems (GCCS); testing, monitoring, reporting 
and record keeping requirements; public hearing requirements; and 
progress reporting requirements. Additionally, this action summarizes 
implementation and delegation of authority of the MSW Landfills Federal 
Plan.

DATES: Comments. Comments must be received on or before October 7, 
2019.
    Public Hearing. We will hold a public hearing on September 6, 2019 
from 1:00 p.m. to 5:00 p.m. (Eastern Daylight Time) in Research 
Triangle Park, North Carolina as specified in the ADDRESSES section of 
this preamble. If no one contacts the EPA requesting to speak at the 
public hearing to be held concerning this action by August 27, 2019, 
the public hearing will not take place. Information regarding whether 
or not a hearing will be held will be posted on the rule's website 
located at https://www.epa.gov/stationary-sources-air-pollution/municipal-solid-waste-landfills-new-source-performance-standards. EPA

mechanisms described in the DATES and ADDRESSES sections of this 
preamble.

II. Background

A. What is the regulatory development background and legal authority 
for this action?

    Under authority of the Clean Air Act (CAA), the EPA has promulgated 
several regulations that apply to MSW landfills. In 1996, under CAA 
section 111, the EPA promulgated the original standards of performance 
for new MSW landfills (i.e., new source performance standards or NSPS) 
at 40 CFR part 60, subpart WWW, and EG for existing MSW landfills at 40 
CFR part 60, subpart Cc (61 FR 9905; March 12, 1996). The NSPS and EG 
are based on the Administrator's determination that MSW landfills 
cause, or contribute significantly to, air pollution that may 
reasonably be anticipated to endanger public health or welfare. In 
1999, the EPA promulgated a federal plan under CAA section 111 to 
implement the 1996 EG for landfills located in states that did not have 
approved and effective state plans (40 CFR part 62, subpart GGG) (64 FR 
60689, November 8, 1999). The federal plan was necessary to implement 
the 1996 EG for MSW landfills located in states and Indian country 
where state plans or tribal plans were not in effect. In 2003, the EPA 
promulgated national emission standards for hazardous air pollutants 
(NESHAP) under CAA section 112 to regulate hazardous air pollutant 
(HAP) emissions from MSW landfills (40 CFR part 63, subpart AAAA) (68 
FR 2227, January 16, 2003). The 2003 NESHAP fulfills the requirements 
of CAA section 112(d), which requires the EPA to regulate HAP listed in 
CAA section 112(b) and helps implement the Urban Air Toxics Strategy 
under CAA section 112(k). To control emissions of HAP from area sources 
in urban areas, the

[[Page 43748]]

EPA developed a strategy identifying 33 HAP that present the greatest 
threat to public health in the largest number of urban areas as the 
result of emissions from area sources. MSW landfills were listed on 
July 19, 1999, as an area source category to be regulated pursuant to 
CAA section 112(k) because 13 of the listed HAP are emitted from MSW 
landfills.
    In 2016, the EPA reviewed and revised the MSW Landfills NSPS at 40 
CFR part 60, subpart XXX, and the EG for existing MSW landfills at 40 
CFR part 60, subpart Cf (81 FR 59276 and 59332, August 29, 2016). For 
the 2016 rulemaking, the EPA reviewed the NSPS and EG based on changes 
in the landfills industry since the rules were first promulgated in 
1996, including changes to the size and number of existing landfills, 
industry practices, and gas control methods and technologies. Based on 
its review, the EPA made several revisions to further reduce emissions 
of landfill gas and its components. The major changes included reducing 
the emissions threshold at which an MSW landfill must install controls 
from 50 megagrams (Mg) per year of nonmethane organic compounds (NMOC) 
to 34 Mg per year NMOC. Additionally, the EPA developed a subcategory 
for closed landfills because closed landfills do not produce as much 
landfill gas (LFG) as an active landfill. Landfills in this subcategory 
remain subject to an NMOC emission threshold of 50 Mg per year for 
determining when controls must be installed or can be removed. The EPA 
is now proposing a federal plan for the 2016 MSW Landfills EG.

B. What is the purpose of this action?

    On August 29, 2016, the EPA promulgated revisions to the 2016 MSW 
Landfills EG. The CAA regulations implementing EG require states with 
existing MSW landfills subject to the EG to submit to the EPA state 
plans to implement and enforce the EG. The state plans to implement the 
2016 MSW Landfills EG were due on May 30, 2017. For states that did not 
submit an approvable plan by that deadline, CAA section 111 and 40 CFR 
60.27(c) and (d) require the EPA to develop, implement, and enforce a 
federal plan for existing MSW landfills located in any state (i.e., 
state, territory, or protectorate) or Indian country that does not have 
an approved state plan that implements the 2016 MSW Landfills EG. This 
action proposes an MSW Landfills Federal Plan to implement the 2016 MSW 
Landfills EG for those areas without an approved state plan. For the 
purposes of this preamble and the proposed MSW Landfills Federal Plan, 
the word ``state'' means any of the 50 United States and the 
protectorates of the United States. The word ``protectorate'' means 
American Samoa, the Commonwealth of Puerto Rico, the District of 
Columbia, Guam, the Northern Mariana Islands, and the Virgin Islands.

C. What is the status of state plan submittals?

    The EPA has received eight plans to implement the 2016 MSW 
Landfills EG, which includes submittals form the following: Arizona 
(one plan covering Maricopa County, one covering Pinal County, and 
another covering the remainder of the state), California, Delaware, New 
Mexico (one plan covering Albuquerque-Bernalillo County and another 
covering the rest of the state), and West Virginia. The EPA has 
proposed action on these state plans, but the actions have not been 
finalized. See e.g., 84 FR 32363 (July 8, 2019) (Arizona); 84 FR 32365 
(July 8, 2019) (Pinal County, Arizona); 84 FR 31278 (July 1, 2019) 
(West Virginia); 84 FR 31279 (July 1, 2019) (Delaware); 84 FR 29138 
(June 21, 2019) (New Mexico and Albuquerque-Bernalillo County); and 84 
FR 36863 (July 30, 2019) (California). The plan from Maricopa County, 
Arizona, was withdrawn on July 3, 2019. The EPA is not aware of any 
tribes that have developed plans to implement the 2016 MSW Landfills EG 
or submitted negative declaration letters. The EPA is proposing this 
MSW Landfills Federal Plan to implement the 2016 MSW Landfills EG in 
states, territories, protectorates, and Indian country, that do not 
have an approved and effective state or tribal plan.
    The MSW landfills covered by the state plans submitted to date 
would not be subject to the MSW Landfills Federal Plan once the state 
plan that includes those MSW landfills has been approved and becomes 
effective. However, MSW landfills located in those states would be 
subject to the federal plan (or portions of the federal plan) in the 
event that the state plan is subsequently disapproved, in whole or in 
part. Table 2 of this preamble summarizes the status of state plans and 
negative declarations as of July 15, 2019.

    As the EPA Regional offices approve implementation plans, they will 
also, in the same action, amend the appropriate subpart of 40 CFR part 
62 to codify their approvals. MSW landfill owners or operators can also 
contact the EPA Regional office for the state in which their MSW 
landfill is located to determine whether there is an approved and 
effective state plan in place.
    Table 3 of this preamble lists the addresses for the EPA Regional 
offices and the states and Indian countries that they cover.

III. What are the designated facilities?

A. What is a designated MSW landfill?

    The designated facility for this MSW Landfills Federal Plan is each 
MSW landfill that (1) commenced construction, reconstruction, or 
modification prior to July 17, 2014, and has not been modified or 
reconstructed since then, and (2) has accepted waste since November 8, 
1987, or has capacity for future waste deposition.
    This MSW Landfills Federal Plan will apply to existing MSW 
landfills located in: (1) Any state or portion of Indian country for 
which a state or tribal plan that implements the 2016 MSW Landfills EG 
has not become effective in whole or in part; (2) any state or portion 
of Indian country for which the state or tribe submitted a negative 
declaration; (3) any state or portion of Indian country with an 
effective state or tribal plan that subsequently is vacated in whole or 
in part; or (4) any state or portion of Indian country with an 
effective plan that subsequently revises any component of the plan 
(e.g., the underlying legal authority or enforceable mechanism) such 
that the state or tribal plan no longer meets the requirements of the 
2016 MSW Landfill EG. An MSW landfill that meets any of these criteria 
is covered by the MSW Landfills Federal Plan until a state or tribal 
plan to implement and enforce the 2016 MSW Landfills EG is approved 
according to the requirements in 40 CFR part 60, subpart B, and becomes 
effective. If a state or tribal plan is approved in part, portions of 
the federal plan will apply to the designated MSW landfills in lieu of 
the disapproved portions of the plan until the state or tribe addresses 
the deficiencies in the plan and the revised plan is approved by the 
EPA.
    If an existing MSW landfill subject to the federal plan increases 
its permitted volume design capacity through vertical or horizontal 
expansion (i.e., is modified) on or after July 17, 2014, it would be 
subject to the MSW Landfills NSPS (40 CFR part 60, subpart XXX) (see 81 
FR 59332, August 29, 2016) and would no longer be subject to the 
federal plan. An existing MSW landfill that makes operational changes 
without increasing the horizontal or vertical dimensions of the 
landfill would continue to be subject to the federal or state plan that 
implements the 2016 MSW Landfills EG, rather than the NSPS.

B. How do I determine if my MSW landfill is covered by an approved and 
effective state plan?

    An approved state or tribal plan is a plan that the EPA has 
reviewed and approved in whole or in part based on the requirements in 
40 CFR part 60, subpart B, to implement and enforce the 2016 MSW 
Landfills EG. Throughout this preamble, references to approved state 
plans apply to both whole state plans and portions of state plans. The 
state plan becomes effective on the date specified in the notice 
published in the Federal Register announcing the EPA's approval. The 
effective date of this action will be 30 days after the final federal 
plan is published in the Federal Register.
    The 2016 MSW Landfills Federal Plan will not apply to landfills 
appropriately covered by an approved and effective state or tribal 
plan. If a state or tribal plan becomes effective before promulgation 
of the federal plan, the promulgated MSW Landfills Federal Plan will 
not apply to landfills appropriately covered by that plan. Promulgation 
of this MSW Landfills Federal Plan does not preclude a state or tribe 
from submitting a plan later. If a state or tribe submits a plan after 
promulgation of the MSW Landfills Federal Plan, the EPA will review and 
approve or disapprove the plan. Upon the effective date of the approved 
state or tribal plan, the federal plan will no longer apply. States and 
tribes are, therefore, encouraged to continue their efforts to develop 
and submit state and tribal plans to the EPA for approval.
    MSW landfill owners or operators can contact the EPA Regional 
office for the state or Indian country in which their MSW landfill is 
located to determine whether there is an approved and effective state 
plan in place. Table 3 of this preamble lists the addresses of the EPA 
Regional offices and the states and Indian countries that they cover.

IV. Elements of the MSW Landfills Federal Plan

    Section 111(d) of the CAA, as amended, 42 U.S.C. 7411(d), requires 
states to develop and implement state plans for MSW landfills to 
implement and enforce the 2016 MSW Landfills EG. This proposed federal 
plan will establish standards in the absence of an approved and 
effective state plan. Because this proposed federal plan will establish 
standards in the absence of an approved and effective state plan, this 
action includes the same elements as a state plan: (1) Identification 
of legal authority and mechanisms for implementation; (2) inventory of 
designated facilities; (3) inventory of emissions; (4) emission limits; 
(5) compliance schedules; (6) process for the EPA or state review of 
site-specific

[[Page 43750]]

design plans for GCCS; (7) testing, monitoring, reporting, and 
recordkeeping requirements; (8) public hearing requirements; and (9) 
progress reporting requirements. This section of the preamble explains 
the proposed federal plan elements. Additionally, Table 4 of this 
preamble identifies each element and indicates where it is located or 
codified.

A. Legal Authority and Enforcement Mechanism

    Section 111(d) of the CAA directs the EPA to develop a federal plan 
for states that do not submit approvable state plans. Section 111 of 
the CAA provides the EPA with the authority to implement and enforce 
the federal plan in cases where the state fails to submit a fully 
satisfactory state plan.

B. Inventory of Designated MSW Landfills

    The docket for this action includes an inventory of the MSW 
landfills that may potentially be covered by this proposed federal plan 
in the absence of approved state or tribal plans. There are an 
estimated 1,913 landfills potentially covered by this proposed federal 
plan. These landfills exist in all 50 states and the U.S. territories 
of Puerto Rico and the Virgin Islands. Additionally, one tribal entity, 
the Salt River Pima Maricopa Indian Community, would be covered by this 
proposed federal plan. The EPA developed the inventory of landfills by 
identifying existing landfills that are expected to be covered by the 
federal plan as of July 15, 2019, using the databases developed for the 
2016 MSW Landfills EG and NSPS. For a discussion of the sources, their 
locations, and information used to develop the source list, see the 
memorandum, Developing a Federal Plan Source and Emission Inventory, 
which is available in the docket for this action. Any MSW landfill that 
meets the applicability criteria in this action will be subject to the 
federal plan, regardless of whether it is listed in the inventory in 
Docket ID No. EPA-HQ-OAR-2019-0338. The EPA requests that states or 
owners or operators identify additional sources for inclusion on the 
list during the comment period for this action.

C. Inventory of Emissions

    The EPA estimated the emissions from the inventory of existing MSW 
landfills that are expected to be covered by the federal plan as of 
July 15, 2019. Pollutant emissions are expressed in Mg NMOC per year in 
calendar year 2019. Table 5 of this preamble summarizes the results of 
the inventory. Although the EPA has proposed to approve some state 
plans in whole or in part, to date none of the actions on the proposed 
state plans have been finalized. Therefore, the inventory includes all 
existing MSW landfills in the U.S. that meet the applicable criteria. 
The inventory will be updated before promulgation of the federal plan 
to exclude sources and emissions that are located in states for which 
an approved state plan is subsequently promulgated.
    The EPA estimated emissions from MSW landfills by first estimating 
the LFG generation rates of landfills identified in the source 
inventory, using a first-order decay equation. The decay equation uses 
default values from Compilation of Air Pollutant Emission Factors (AP-
42) for the methane generation potential (L0), the methane 
generation rate (k), and the NMOC concentration.\1\ Next, the EPA 
estimated when the MSW landfills in the source inventory would control 
emissions under the previous regulatory level (NMOC emissions of 50 Mg 
per year). To determine the timing of these controls, the EPA modeled 
emissions using Tier 1 default values from 40 CFR part 60, subpart WWW 
for the L0 and k, but applied the NMOC concentration in AP-
42 for determining when MSW landfills would meet the regulatory NMOC 
emissions threshold. The Tier 1 default values in subpart WWW for 
L0 and k are conservatively high for the purpose of 
estimating actual emissions; therefore, they are used only for 
estimating uncontrolled emissions to determine when MSW landfills could 
exceed the threshold and be required to install a GCCS. The EPA also 
factored in lag times to account for the initial 30-month time period 
between when the MSW landfill exceeds the emission rate threshold until 
the MSW landfill must install and operate controls, and the periodic 
expansion of the GCCS into new areas of waste placement (5 years for 
active areas and 2 years for areas that are closed or at final grade). 
After determining the timing of controls required by the regulation, 
the actual amount of collected gas was estimated using AP-42 defaults 
for L0, k, and NMOC, and an assumed collection efficiency of 
85 percent and an assumed destruction efficiency of 98 percent. The 
remaining emissions, after considering controls, represent the modeled 
NMOC emissions based on LFG generation and AP-42 default parameters 
minus the emission reductions. See the memorandum, Developing a Federal 
Plan Source and Emission Inventory, which is available in the docket 
for this action, for the complete emissions inventory, including 
detailed emissions from MSW landfills in each state, and details on the 
calculations used to determine those emissions. These estimates are 
based solely on the modeled emissions remaining after considering 
controls required by 40 CFR part 60, subparts WWW and Cc, and do not 
include any additional emissions reductions from voluntary actions, 
such as early installation of the GCCS.

D. Emission Limits and Operating Limits

    This proposed federal plan contains emission limits that correspond 
to the 2016 MSW Landfills EG, which are summarized in section V.C of 
this preamble. In accordance with 40 CFR 60.27(e), this action does not 
propose to revise the final limits. Instead, it proposes to implement 
the emission limits as promulgated in the 2016 MSW Landfills EG for 
existing sources in states that do not have an approved state plan.

E. Compliance Schedule

    According to 40 CFR 60.24(e)(1), increments of progress are 
required for any compliance schedule that is longer than 12 months. The 
proposed federal plan would require owners or operators of existing MSW 
landfills with design capacities equal to or greater than 2.5 million 
Mg and 2.5 million cubic meters (m\3\) to install GCCS within 30 months 
of reaching or exceeding 34 Mg per year NMOC. This proposed federal 
plan would require owners or operators of existing closed MSW 
landfills--those that have submitted a closure report as specified in 
40 CFR 62.724(f) with design capacities equal to or greater than 2.5 
million Mg and 2.5 million m\3\--to install GCCS within 30 months of 
reaching or exceeding 50 Mg per year NMOC. This proposed federal plan 
includes increments of progress, which are the primary mechanisms for 
ensuring progress toward final compliance with the emission guidelines. 
Each increment of progress has a specified date for achievement 
described in section V.B of this preamble.

F. Process for Review and Approval of Site-Specific Design Plans

    The 2016 MSW Landfills EG requires plans to include a process for 
review and approval of site-specific design plans for required GCCS 
(see 40 CFR 60.38f(d)). As previously discussed, if the existing MSW 
landfill has (1) a design capacity equal to or greater than 2.5 million 
Mg and 2.5 million m\3\ and (2) NMOC emissions equal to or exceeding 34 
Mg per year (50 Mg per year for the closed landfill subcategory), the 
landfill owner or operator must submit the cover page containing the 
engineer's seal of the site-specific design plan. The EPA Regional 
office will make a decision within 90 days about whether the entire 
plan should be submitted for review. In cases where the state or tribe 
has been delegated authority to implement this aspect of the federal 
plan, the state or tribe would review the design plans. See section VI 
of this preamble for a discussion of federal plan delegation.
    When the EPA opts to review the entire plan, the EPA intends to 
review design plans as expeditiously as possible to allow sufficient 
time after approval of the plans for the landfills to install controls 
prior to the compliance date. The EPA will initially review the design 
plans for completeness and the source will be notified if any items are 
missing. The EPA will then review the plans for acceptability, and, 
once that review is completed, the EPA will notify the source and the 
state or tribe in writing of the acceptability of the plan. If the plan 
is not acceptable, the source will be given an appropriate amount of 
time to make the necessary changes. However, the date by which a GCCS 
must be completed and in compliance remains unchanged, i.e., 30 months 
after the emission rate report first shows NMOC emissions greater than 
or equal to 34 Mg per year (50 Mg per year for the closed landfill 
subcategory).

G. Testing, Monitoring, Recordkeeping, and Reporting Requirements

    The proposed federal plan includes testing, monitoring, 
recordkeeping, and reporting requirements, as described in sections V.D 
and E of this preamble. These proposed requirements correspond with the 
2016 MSW Landfills EG. Testing, monitoring, recordkeeping, and 
reporting requirements will assure initial and ongoing compliance.

H. Requirement for Public Hearing

    According to 40 CFR 60.27(f), the EPA must provide the opportunity 
for a public hearing prior to promulgation of

[[Page 43752]]

a federal plan. For this MSW Landfills Federal Plan, the EPA will offer 
the opportunity for a public hearing in Research Triangle Park, North 
Carolina, as specified in the ADDRESSES and DATES sections of this 
preamble.

V. Summary of Proposed MSW Landfills Federal Plan Requirements

A. What are the proposed applicability requirements?

    The proposed federal plan applicability criteria (40 CFR 62.711) 
reflect the 2016 MSW Landfills EG (40 CFR 60.31f). The designated 
facility for this MSW Landfills Federal Plan is described in section 
III.A of this preamble.

B. What are the proposed compliance schedules?

    Owners or operators of MSW landfills subject to the federal plan 
will be required to submit a design capacity report within 90 days 
after the effective date of the federal plan (40 CFR 62.724(a)). If the 
design capacity indicates a capacity equal to or greater than 2.5 
million Mg and 2.5 million m\3\ of solid waste a landfill can accept, 
an annual NMOC emission rate report must also be submitted within 90 
days after the effective date of the federal plan and then every 12 
months until the landfill installs a GCCS (40 CFR 62.724(c)).
    If the first NMOC emission rate report shows emissions less than 34 
Mg per year NMOC (50 Mg per year for the closed landfill subcategory), 
then the owner or operator must recalculate NMOC emissions annually and 
submit annual NMOC emission rate reports unless the MSW landfill is 
closed. (See 40 CFR 62.718 for conditions under which 5-year reports 
rather than annual reports may be submitted.) If an emission rate 
report shows that NMOC emissions equal or exceed 34 Mg per year, the 
owner or operator must begin following enforceable increments of 
progress to install a GCCS within 30 months of reaching or exceeding 34 
Mg per year NMOC (40 CFR 62.712). Therefore, the generic schedule for 
the increments of progress starts with the date of the first annual 
emission rate report that shows NMOC emissions equal or exceed 34 Mg 
per year (50 Mg per year for the closed landfill subcategory) (40 CFR 
62.712(c)). Alternatively, a landfill may follow Tier 4 as discussed 
later in this section (40 CFR 62.718(a)(6)). For the closed landfill 
subcategory, if an emission rate report shows that NMOC emissions equal 
or exceed 50 Mg per year, the owner or operator must begin following 
enforceable increments of progress to install a GCCS within 30 months 
of reaching or exceeding 50 Mg per year NMOC.
    This proposed MSW Landfills Federal Plan includes the five 
increments of progress and provides flexibility to establish the 
increment dates (40 CFR 62.712). The proposed MSW Landfills Federal 
Plan contains a generic compliance schedule (Table 1 to 40 CFR part 62, 
subpart OOO) that applies to designated MSW landfills unless the EPA 
approves an alternative schedule according to the criteria in 40 CFR 
60.27(e)(2).
    The five mandatory increments of progress are as follows:
    1. Submit final control plan (design plan)--1 year after the first 
annual emission rate report showing NMOC emissions >=34 Mg per year 
(>=50 Mg per year for the closed landfill subcategory).
    2. Award contracts for control systems or orders for purchase of 
components--20 months after the first annual emission rate report 
showing NMOC emissions >=34 Mg per year (>=50 Mg per year for the 
closed landfill subcategory).
    3. Begin on-site construction or installation of the GCCS--24 
months after the first annual emission rate report showing NMOC 
emissions >=34 Mg per year (>=50 Mg per year for the closed landfill 
subcategory).
    4. Complete on-site construction or installation of the GCCS--30 
months after the first annual emission rate report showing NMOC 
emissions >=34 Mg per year (>=50 Mg per year for the closed landfill 
subcategory).
    5. Achieve final compliance--30 months after the first annual 
emission rate report showing NMOC emissions >=34 Mg per year (>=50 Mg 
per year for the closed landfill subcategory). Note that the initial 
performance test to demonstrate compliance must be conducted within 180 
days after the date the landfill is required to achieve final 
compliance.
    The date for the first, fourth, and fifth increments is established 
in the 2016 MSW Landfill EG. According to 40 CFR 60.27(e)(1), federal 
plan compliance times may be no less stringent than those established 
in the EG.
    The EPA selected the proposed dates for the middle two increments 
(awarding contract and initiating on-site construction) to allow a 
reasonable period of time for MSW landfills to complete these 
activities. These increments of progress are required by 40 CFR 60.24, 
but dates are not specified in the 2016 MSW Landfills EG. The EPA 
established these dates to match the dates included in the previous 
federal plan for MSW landfills (40 CFR part 62, subpart GGG) because 
the two plans require the same increments of progress to achieve 
compliance. The proposed date for awarding contracts is 20 months after 
the first annual NMOC emission rate report showing NMOC emissions 
greater than or equal to 34 Mg per year (50 Mg per year for the closed 
landfill subcategory), which is 8 months after the proposed date that 
the design plan is due. This 8-month time frame would allow adequate 
time for the regulatory agency to review and approve the design plan 
and for the MSW landfill owner or operator to solicit bids based on the 
design plan and award the contract(s).
    The proposed date for initiating on-site construction is 24 months 
after the first annual emission report showing NMOC emissions greater 
than or equal to 34 Mg per year (50 Mg per year for the closed landfill 
subcategory) is due (4 months after contract award). This 4-month 
period would allow time for the contractor to mobilize and obtain 
materials necessary to begin construction. A later date would not be 
practical because the date for completing on-site construction and 
final compliance is 30 months after the first annual emission rate 
report showing NMOC emissions greater than or equal to 34 Mg per year 
(50 Mg per year for the closed landfill subcategory). If construction 
is not initiated by 24 months after the first annual emission rate 
report showing NMOC emissions greater than or equal to 34 Mg per year 
(50 Mg per year for the closed landfill subcategory), it is unlikely 
that the construction could be completed by the final compliance date. 
Some MSW landfills may want to initiate on-site construction earlier to 
assure that they can meet the final compliance date. The fourth 
increment, completion of on-site construction, would need to be 
completed by the final compliance date (increment 5) in order for the 
landfill to achieve compliance.
    Owners and operators employing Tier 4 would follow the generic 
compliance schedule for Tier 4 landfills in Table 1 to 40 CFR part 62, 
subpart OOO. Increment 1 is triggered by the first measured 
concentration of methane of 500 parts per million (ppm) or greater, 
rather than the initial NMOC emission rate report showing NMOC 
emissions 34 Mg per year or greater. Landfills employing Tier 4 would 
continue to submit an annual NMOC emission rate report (40 CFR 
62.724(c)). Timing of increments 2 through 5 for Tier 4 landfills are 
based on the most recent NMOC emission rate report showing NMOC 
emissions 34 Mg per year or greater.

[[Page 43753]]

    For all landfills, the EPA recognizes that flexibility may be 
needed for increment 2 (award contract) and increment 3 (begin 
construction) given facility-specific GCCS considerations and 
constraints. Therefore, the EPA will accept facility-specific 
compliance schedules from MSW landfill owners or operators, as allowed 
under 40 CFR 60.27(e)(2).
    The MSW landfill owner or operator would submit alternative dates 
for increments 2 and 3 and a justification to the EPA at the time the 
final control plan is due (40 CFR 62.724(p)). If the MSW landfill owner 
or operator is submitting the alternative dates for these increments, 
the owner or operator should also send a copy to the appropriate state 
or tribe. The EPA is allowing alternative dates for increments 2 and 3 
to provide flexibility to MSW landfill owners or operators. However, 
owners or operators using alternate dates for increments 2 and 3 must 
continue to meet the required dates for increments 1, 4, and 5. The EPA 
would review the schedule and coordinate with the owner or operator.

C. What emissions and operating limits is the EPA proposing to 
incorporate into the federal plan?

    The EPA is proposing that an MSW landfill subject to the federal 
plan must install and operate a GCCS that meets specified emissions and 
operating limits (40 CFR 62.714 and 40 CFR 62.716), if the NMOC 
emissions rate is 34 Mg per year or more (50 Mg per year or more for 
the closed landfill subcategory). The standards would require owners or 
operators to operate the GCCS at a negative pressure at each wellhead 
(except during certain specified conditions), operate the interior 
wellhead at a temperature less than 55 degrees Celsius (131 degrees 
Fahrenheit), and operate the collection system so that the methane 
concentration is less than 500 ppm above background at the surface of 
the landfill (40 CFR 62.716(b-(d)). The owner or operator of a landfill 
must control the collected gas by routing it to either: (1) A non-
enclosed flare designed and operated according to the requirements of 
40 CFR 60.18, (2) an enclosed control device achieving 98-percent NMOC 
reduction or an outlet concentration of 20 ppm NMOC by volume or less, 
or (3) a gas treatment system that processes the collected gas for 
subsequent sale or beneficial use (40 CFR 62.714(c)).
    The proposed requirements of the federal plan are the same as the 
requirements of the 2016 MSW Landfills EG as published on August 29, 
2016 (81 FR 59276). However, this proposed federal plan applies a 
technical correction to the compliance provisions section and the 
corresponding reporting requirement in the reporting section. Those 
corrections appear in this proposed federal plan at 40 CFR 
62.720(a)(3)(ii) and 40 CFR 62.724(h)(7) and would ensure that the 
owner or operator conducts a corrective action analysis, develops an 
implementation schedule, and reports corrective action(s) to address 
not only positive pressure, but also elevated temperature.

D. What are the proposed performance testing and monitoring 
requirements?

1. NMOC Emissions Rate
    The EPA proposes that, to determine if a GCCS is required, the 
owner or operator must determine NMOC emissions using one or both of 
the two emission rate equations in the rule and one of four optional 
methods to determine the model inputs (referred to as tier methods in 
the rule) (40 CFR 62.718(a)). Tier 1 uses default assumptions for 
methane generation rate and NMOC concentration in the emissions model 
(40 CFR 62.718(a)(2)). Tier 2 requires testing to determine a site-
specific NMOC concentration. Tier 3 requires testing to determine a 
site-specific NMOC concentration and methane generation rate (40 CFR 
62.718(a)(4)). Any MSW landfill that exceeds the NMOC emissions 
threshold using Tier 2 or 3 would install a GCCS, unless the owner or 
operator chooses to use Tier 4 (40 CFR 62.718(a)(6)).
    Tier 4 is based on surface emissions monitoring (SEM) to 
demonstrate that surface emissions are low (40 CFR 62.718(a)(6)). An 
owner or operator can use Tier 4 only if the MSW landfill owner or 
operator can demonstrate that NMOC emissions are greater than or equal 
to 34 Mg per year but less than 50 Mg per year using Tier 1 or Tier 2. 
An MSW landfill employing Tier 4 that can demonstrate that surface 
emissions are below 500 ppm for four consecutive quarters would not 
trigger the requirement to install a GCCS even if Tier 1, 2, or 3 
calculations indicate that the 34 Mg per year threshold has been 
exceeded. However, once SEM demonstrates emissions exceeding 500 ppm 
(40 CFR 62.718(a)(6)(v)), the MSW landfill would be required to install 
a GCCS according to the schedule in section V.B. of this preamble and 
Table 1 to subpart OOO of part 62.
2. Gas Collection System Monitoring
    The EPA proposes that the landfill gas collection system must be 
equipped with a sampling or access port and the owner or operator must 
periodically monitor gauge pressure in the gas collection header, 
monitor nitrogen or oxygen content in the landfill gas, and monitor 
temperature of the landfill gas (40 CFR 62.722(a)).
3. Flare Monitoring
    The EPA proposes that, if a flare is used, the owner or operator 
must monitor the flare using a heat sensing device that indicates 
presence of a flame and a device that records flow to the flare and any 
bypass lines (40 CFR 62.722(c)).
4. Control Device Testing and Monitoring
    The EPA proposes that, if an enclosed control device is used, the 
owner or operator must conduct an initial performance test (40 CFR 
62.714(c)). The owner or operator must then operate the device as 
required by the manufacturer's specifications, install a temperature 
monitoring device, and install a device that records flow to the 
control device and any bypass lines (40 CFR 62.722(b)). A temperature 
monitoring device is not required for boilers or process heaters with a 
design heat capacity of 44 megawatts or greater (40 CFR 62.722(b)(1)).

E. What are the proposed recordkeeping and reporting requirements?

    The EPA proposes that owners and operators must retain records of 
all required monitor readings (40 CFR 62.726). Owners or operators must 
submit certain required performance test reports, NMOC emission rate 
reports, and annual reports documenting compliance and any deviations 
from the operating standards in the federal plan (40 CFR 62.724). All 
required reports must be submitted through the EPA's Central Data 
Exchange (CDX) using the Compliance and Emissions Data Reporting 
Interface (CEDRI) (40 CFR 62.724(j)). Owners or operators are allowed 
to maintain electronic copies of the records in lieu of hardcopies to 
satisfy federal recordkeeping requirements.
    The requirement to submit performance test data electronically to 
the EPA would apply only to those performance tests conducted using 
test methods that are supported by the Electronic Reporting Tool (ERT). 
A listing of the pollutants and test methods supported by the ERT is 
available at: https://www3.epa.gov/ttn/chief/ert/ert_info.html. When 
the EPA adds new methods to the ERT, a notice will be sent out through 
the Clearinghouse for Inventories and Emissions Factors (CHIEF) 
Listserv

[[Page 43754]]

(https://www.epa.gov/airemissions-inventories/emissionsinventory-listservs) and a notice of availability will be added to the ERT 
website. You are encouraged to check the ERT website regularly for up-
to-date information on methods supported by the ERT.

VI. Implementation of the Federal Plan and Delegation

A. Background of Authority

    Under section 111(d) of the CAA, the EPA is required to adopt EG 
that are applicable to existing MSW landfills. These EG are implemented 
when the EPA approves a state or tribal plan or adopts a federal plan 
that implements and enforces the EG. As discussed above, this action 
would regulate existing MSW landfills in states or Indian country that 
do not have approved plans in effect to implement the EG.
    Congress has determined that the primary responsibility for air 
pollution prevention and control rests with state, tribal and local 
agencies. See CAA section 101(a)(3). Consistent with that overall 
determination, Congress established CAA section 111(d) with the intent 
that state, tribal and local agencies take the primary responsibility 
for ensuring that the standards of performance and other requirements 
in the EG are achieved. Also, Congress explicitly required that the EPA 
establish procedures that are like those under CAA section 110 for 
state implementation plans. Although Congress required the EPA to 
propose and promulgate a federal plan for states and tribes that fail 
to submit approvable state plans on time, states may submit plans after 
promulgation of this federal plan. The EPA strongly encourages states 
and tribes that are unable to submit approvable plans to request 
delegation of the federal plan so that they can have primary 
responsibility for implementing the 2016 MSW Landfills EG, consistent 
with the intent of Congress.
    The preferred outcome under the statute and the regulations results 
when the state, tribal, and local agencies implement an EPA-approved 
state or tribal plan because state, tribal, and local agencies not only 
have the responsibility to implement the 2016 MSW Landfills EG, but 
also have the practical knowledge and enforcement resources critical to 
achieving the highest rate of compliance. In cases where states are 
unable to develop and submit approvable state or tribal plans, it is 
still preferable for the state, tribal and local agencies to be the 
implementing agency. For these reasons, the EPA will do all that it can 
to expedite delegation of the federal plan to state, tribal, and local 
agencies, whenever possible, in cases where states or tribes are unable 
to develop and submit approvable state or tribal plans. The EPA will 
also continue to review and approve state or tribal plans after 
promulgation of this federal plan.

B. Mechanisms for Transferring Authority

    There are two mechanisms for transferring implementation authority 
to state, tribal, and local agencies: (1) The EPA's approval of a state 
plan after the federal plan is in effect; and (2) if a state does not 
submit or obtain approval of its own plan, the EPA's delegation to a 
state, tribe, or local agency is transferred with the authority to 
implement certain portions of this federal plan to the extent 
appropriate and if allowed by state law. Both options are described in 
more detail below.
1. Federal Plan Becomes Effective Prior to Approval of a State Plan
    After MSW landfills in a state become subject to the federal plan, 
the state or tribal agency may still adopt and submit a state or tribal 
plan to the EPA. If the EPA determines that the state or tribal plan 
meets the requirements of the 2016 MSW Landfills EG, the EPA will 
approve the state or tribal plan. If the EPA determines that the plan 
does not meet the requirements of the 2016 MSW Landfills EG, the EPA 
will approve the portions of the plan that are consistent with the 2016 
MSW Landfills EG. If a state or tribal plan is approved in part, 
portions of the federal plan will apply to the designated MSW landfills 
in lieu of the disapproved portions of the state or tribal plan until 
the state or tribe addresses the deficiencies in the state or tribal 
plan and the revised plan is approved by the EPA. Prior to any 
disapproval, the EPA will work with states and tribes in an attempt to 
reconcile areas of the plan that remain inconsistent with the EG.
    Upon the effective date of a state or tribal plan, the federal plan 
will no longer apply to MSW landfills covered by such a plan. The 
state, tribe, territory, or local agency would implement and enforce 
the state plan in lieu of the federal plan. When an EPA Regional office 
approves a state or tribal plan, it will amend the appropriate subpart 
of 40 CFR part 62 to indicate such approval.
2. State, Tribe, Territory, or Local Agency Taking Delegation of the 
Federal Plan
    The EPA, in its discretion, may delegate to state, tribe, 
territorial, or local agencies the authority to implement this proposed 
federal plan. As discussed above, the EPA has concluded that it is 
advantageous and the best use of resources for states, tribes, 
territories, or local agencies 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 federal, 
state, tribal, territorial, or local law. If a state, tribe, territory, 
or local agency requests delegation, the EPA will generally delegate 
the entire federal plan to the state, tribe, territory, or local 
agency. These functions include administration and oversight of 
compliance, reporting and recordkeeping requirements, MSW landfill 
inspections, and preparation of draft notices of violation, but will 
not include any authorities retained by the EPA. Agencies that have 
taken delegation, as well as the EPA, will have responsibility for 
bringing enforcement actions against sources violating federal plan 
provisions.

C. Implementing Authority

    The EPA Regional Administrators have been delegated the authority 
for implementing the MSW Landfills Federal Plan. All reports required 
by the federal plan should be submitted to the appropriate Regional 
Administrator. Table 3 of this preamble lists the addresses for the EPA 
Regional offices and the states they cover.

D. Delegation of the Federal Plan and Retained Authorities

    If a state, tribe, territory, or local agency intends to take 
delegation of the federal plan, the state, tribe, territory, or local 
agency should submit a written request for delegation of authority to 
the appropriate EPA regional office. The state, tribe, territory, or 
local agency should explain how it meets the criteria for delegation. 
See Good Practices Manual for Delegation of NSPS and NESHAP (U.S. EPA, 
February 1983). The letter requesting delegation of authority to 
implement the federal plan should: (1) Demonstrate that the state, 
tribe, territory, or local agency has adequate resources, as well as 
the legal authority to administer and enforce the program; (2) include 
an inventory of designated MSW landfills, which includes those that 
have ceased operation, but have not been dismantled or rendered 
inoperable, and an

[[Page 43755]]

inventory of the designated units' air emissions and a provision for 
progress reports to the EPA; (3) certify that a public hearing was held 
on the state, tribe, territory, or local agency delegation request; and 
(4) include a memorandum of agreement between the state, tribe, 
territory, or local agency 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 notice in 
the Federal Register, thereby incorporating the delegation of authority 
into the appropriate subpart of 40 CFR part 62.
    If authority is not delegated to a state, tribe, territory, or 
local agency, the EPA will implement the federal plan. Also, if a 
state, tribe, territory, or local agency fails to properly implement a 
delegated portion of the federal plan, the EPA will assume direct 
implementation and enforcement of that portion. The EPA will continue 
to hold enforcement authority along with the state, tribe, territory, 
or local agency even when the agency has received delegation of the 
federal plan. In all cases where the federal plan is delegated, the EPA 
will retain and will not transfer authority to a state, tribe, or local 
agency to approve the following items promulgated in 40 CFR 62.710(b)): 
(1) Approval of alternative methods to determine the site-specific NMOC 
concentration or a site-specific methane generation rate constant (k); 
(2) alternative emission standards; (3) major alternatives to test 
methods (Major alternatives to test methods or to monitoring are 
modifications made to a federally enforceable test method or to a 
federal monitoring requirement. These changes would involve the use of 
unproven technology or procedures or an entirely new method, which is 
sometimes necessary when the required test method or monitoring 
requirement is unsuitable.); and (4) waivers of recordkeeping.
    Any MSW landfill owners or operators who wish to petition the 
agency for an alternative requirement to those in 40 CFR 62.710(b) 
should submit a request to the appropriate Regional Administrator with 
a copy sent to the appropriate state.

VII. Title V Operating Permits

    Existing landfills with design capacities less than 2.5 million Mg 
or 2.5 million m\3\ are not required to have a title V operating 
permit, unless they are a major source or are subject to title V (part 
70 or part 71) for some other reason (e.g., subject to a CAA section 
112 NESHAP or to another CAA section 111 NSPS). All existing MSW 
landfills with design capacities equal to or greater than 2.5 million 
Mg and 2.5 million m\3\ must have a title V operating permit. Existing 
MSW landfills that are not currently subject to title V permitting 
because their design capacity is less than 2.5 million Mg or 2.5 
million m\3\ may trigger the requirement to apply for a title V permit 
in the future if the landfill's design capacity increases to equal or 
exceed 2.5 million Mg and 2.5 million m\3\. Such sources, newly subject 
to the requirement to obtain a title V permit for operating the MSW 
landfill at or above the 2.5 million Mg or 2.5 million m\3\ capacity, 
become subject to the title V program 90 days after the effective date 
of this federal plan, even if the design capacity report is submitted 
prior to that date. This date that triggers title V applicability is 
consistent with the published EG. The requirements of a federal plan 
are applicable requirements for title V sources covered by a federal 
plan. Additional information for filing a timely title V application 
should be obtained at the permitting authority. See 40 CFR 
70.5(a)(1)(i) or 71.5(a)(1)(i).
    An MSW landfill that is closed and is no longer subject to title V 
as a result of this federal plan, once finalized, may remain subject to 
title V permitting requirements for another reason or reasons. See 40 
CFR 62.711(e) and 40 CFR 70.3 or 71.3. In such circumstances, the 
landfill would be required to continue operating in compliance with a 
title V permit.

VIII. Statutory and Executive Order Reviews

    Additional information about these statutes and Executive Orders 
can be found at https://www.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 action is not a significant regulatory action and was, 
therefore, not submitted to the Office of Management and Budget (OMB) 
for review.

B. Executive Order 13771: Reducing Regulation and Controlling 
Regulatory Costs

    This action is not expected to be an Executive Order 13771 
regulatory action because this action is not significant under 
Executive Order 12866.

C. Paperwork Reduction Act (PRA)

    This action does not impose any new information collection burden 
under the PRA. This action simply proposes the MSW Landfills Federal 
Plan to implement the 2016 MSW Landfills EG for those states that do 
not have a state plan implementing the EG. OMB has previously reviewed 
the information collection activities contained in the 2016 MSW 
Landfills EG and has assigned OMB control number 2060-0720.

D. Regulatory Flexibility Act (RFA)

    I certify that this action will not have a significant economic 
impact on a substantial number of small entities under the RFA. The 
small entities subject to the requirements of this action are small MSW 
landfills. The Agency has determined that up to 15 small entities, 
representing approximately 13 percent of the total number of small 
entities subject to the proposal, may experience an impact of greater 
than 3 percent of sales or revenues. A summary of this analysis is 
available in the memorandum, Small Entity Screening Assessment for 
Proposed Federal Plan for Emission Guidelines and Compliance Times for 
Municipal Solid Waste Landfills, which is available in the docket for 
this action. More details of the general economic analysis of the EG, 
which this action implements, are available in the docket for the 2016 
MSW Landfills EG (Docket ID Item No. EPA-HQ-OAR-2014-0451-0225).
    Although not required by the RFA to convene a Small Business 
Advocacy Review (SBAR) Panel because the EPA has now determined that 
this proposal would not have a significant economic impact on a 
substantial number of small entities, there was substantial interest in 
the revision of the EG among small entities. Thus, during development 
of the 2016 MSW Landfills EG, the EPA conducted stakeholder outreach as 
detailed in sections XI.C and XI.E of the preamble to the proposed 
Standards of Performance for MSW Landfills (79 FR 41828-41829; July 17, 
2014) and in sections VIII.C and VIII.E of the preamble to the 2016 MSW 
Landfills EG (81 FR 59309-59310; August 29, 2016). The EPA convened an 
SBAR Panel in 2013 for the MSW Landfills NSPS and EG rulemakings. The 
EPA originally planned a review of the EG and NSPS in one action, but 
the actions were subsequently divided into separate rulemakings. The 
SBAR Panel evaluated the assembled materials and small entity comments 
on issues related to the rule's potential effects and significant 
alternative regulatory approaches. A copy of the Summary of Small 
Entity Outreach is available in the docket for the 2016 MSW Landfills 
EG (Docket ID

[[Page 43756]]

Item No. EPA-HQ-OAR-2014-0451-0012). While formulating the provisions 
of the EG, the EPA considered the input provided over the course of the 
stakeholder outreach as well as the input provided in the many public 
comments and incorporated many of the suggestions in the 2016 MSW 
Landfills EG.

E. Unfunded Mandates Reform Act (UMRA)

    This action does not contain any unfunded mandate as described in 
UMRA, 2 U.S.C. 1531-1538. This action implements mandates specifically 
and explicitly set forth in 40 CFR 60.27 without the exercise of any 
policy discretion by the EPA.
    We note, however, that the EG may affect small governments because 
small governments operate landfills (80 FR 52146, August 27, 2015). 
This action implements the promulgated EG. In developing the final 2016 
MSW Landfills EG, the EPA consulted with small governments pursuant to 
a plan established under section 203 of the UMRA to address impacts of 
regulatory requirements in the rule that might significantly or 
uniquely affect small governments. The EPA also held meetings as 
discussed in section VIII.F of this preamble.

F. Executive Order 13132: Federalism

    The EPA has concluded that this action may have federalism 
implications, because the rule imposes substantial direct compliance 
costs on state or local governments, and the federal government will 
not provide the funds necessary to pay those costs. The EPA provided 
the following federalism summary impact statement for the 2016 MSW 
Landfills EG. The EPA consulted with state and local officials early in 
the process of developing the 2016 MSW Landfills EG to permit them to 
have meaningful and timely input into its development. In developing 
the regulatory options reflected in the proposed and final 2016 MSW 
Landfills EG, the EPA consulted with eight national organizations 
representing state and local elected officials. Additionally, the 
Environmental Council of the States, the National Association of Clean 
Air Agencies, and the Association of State and Territorial Solid Waste 
Management Officials participated in preproposal briefings. Finally, in 
addition to these associations, over 140 officials representing state 
and local governments across the nation participated in at least one of 
three preproposal briefings in the fall of 2013 (September 10, 2013, 
November 7, 2013, and November 14, 2013), which is summarized in the 
docket for the 2016 MSW Landfills EG (Docket ID Item No. EPA-HQ-OAR-
2014-0451-0013). The EPA received comments from over 40 entities 
representing state and local governments. The EPA conducted an 
additional Federalism outreach meeting on April 15, 2015.
    The principal intergovernmental concerns raised during the 
preproposal consultations, as well as during the proposed rule's public 
comment period, include: (1) Implementation concerns associated with 
shortening of GCCS installation and/or expansion timeframes; (2) 
concerns regarding significant lowering of the design capacity or 
emission thresholds; (3) the need for clarifications associated with 
wellhead operating parameters; and (4) the need for consistent, clear, 
and rigorous surface monitoring requirements. In response to these 
comments and based upon the available data, the EPA decided not to 
adjust the design capacity or significantly lower the emission 
threshold. The EPA also decided not to adjust the time allotted for 
installation of the GCCS or expansion of the wellfield. In the proposed 
MSW Landfills EG (80 FR 52121, August 27, 2015), the EPA highlighted 
specific concerns raised by commenters, which included state agencies 
as well as landfill owners and operators, about the interaction between 
shortened lag times and design plan approvals, costs, and safety 
concerns associated with reduced lag times, and the need for 
flexibility for lag time adjustments. The EPA adjusted wellhead 
operating parameters to limit corrective action requirements to 
negative pressure and temperature. The EPA also acknowledged concerns 
about wellhead operating parameters in 80 FR 52121 (August 27, 2015) 
and considered public comments in favor of and against retention of the 
parameters.
    A complete list of the comments from state and local governments 
was provided to OMB and was placed in the docket for the 2016 MSW 
Landfills EG (Final Report of the Small Business Advocacy Review Panel 
on EPA's Planned Proposed Rules Standards of Performance for Municipal 
Solid Waste Landfills and Review of Emissions Guidelines for Municipal 
Solid Waste Landfills, Docket ID Item No. EPA-HQ-OAR-2014-0451-0139). 
In addition, the detailed response to comments from these entities is 
contained in the EPA's Response to Comments document for the 2016 MSW 
Landfills EG (Docket ID Item No. EPA-HQ-OAR-2014-0451-0229). As 
required by section 8(a) of Executive Order 13132, the EPA included a 
certification from its Federalism official stating that the EPA had met 
the Executive Order's requirements in a meaningful and timely manner 
when it sent the draft of the 2016 MSW Landfills EG to OMB for review 
pursuant to Executive Order 12866. A copy of the certification is 
included in the record for the 2016 MSW Landfills EG (Outreach under 
Executive Order 13132 for MSW Landfills, Docket ID Item Nos. EPA-HQ-
OAR-2014-0451-0013 and EPA-HQ-OAR-2014-0451-0100).

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

    This action has tribal implications as specified in Executive Order 
13175. This action will neither impose substantial direct compliance 
costs on federally recognized tribal governments nor preempt tribal 
law. The database used to estimate impacts of the 2016 MSW Landfills 
EG, identified one tribe, the Salt River Pima-Maricopa Indian 
Community, which owns three landfills potentially subject to this 
federal plan. One of these landfills is open, the Salt River Landfill, 
and is already controlling emissions under the current NSPS/EG 
framework, so while subject to this subpart, the costs of this proposal 
are not substantial. The two other landfills are closed and anticipated 
to meet the definition of the closed landfill subcategory. One of the 
closed landfills, the Tri Cities Landfill, is already controlling 
emissions under the current NSPS/EG framework and will not incur 
substantial additional compliance costs under the federal plan. The 
other landfill, North Center Street Landfill, is not estimated to 
install controls under the federal plan. The EPA will consult with 
tribal officials under the EPA Policy on Consultation and Coordination 
with Indian Tribes in the process of developing this action to permit 
them to have meaningful and timely input into its development. A 
summary of that consultation will be provided in the docket for this 
action once completed.

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

    The EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that concern environmental health or safety risks 
that the EPA has reason to believe may disproportionately affect 
children, per the definition of ``covered regulatory action'' in 
section 2-202 of the Executive Order. This action is not subject to 
Executive Order 13045

[[Page 43757]]

because it implements a previously promulgated federal standard.

I. Executive Order 13211: Actions Concerning Regulations That 
Significantly Affect Energy Supply, Distribution, or Use

    This action is not subject to Executive Order 13211 because it is 
not a significant regulatory action under Executive Order 12866.

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

    This action involves technical standards. The EPA proposes to use 
EPA Methods 2, 2E, 3, 3A, 3C, 18, 21, 25, 25A, and 25C of 40 CFR part 
60, appendix A. The EPA identified 15 voluntary consensus standards 
(VCS) as being potentially applicable (ASTM D3154-00 (2006), ASTM 
D3464-96 (2007), ASTM D3796-90 (2001), ANSI/ASME PTC 19-10-1981 Part 
10, ASME B133.9-1994 (2001), ISO 10396:1993 (2007), ISO 12039:2001, ISO 
10780:1994, ASTM D5835-95 (2013), ASTM D6522-11, ASTM D6420-99 (2010), 
CAN/CSA Z223.2-M86 (1999), ASTM D6060-96 (2009), ISO 14965:2000(E), EN 
12619(1999)). The EPA determined that 14 of the 15 candidate VCS 
identified for measuring emissions of pollutants or their surrogates 
subject to emission standards in the rule would not be practical due to 
lack of equivalency, documentation, validation data, and other 
important technical and policy considerations. The agency identified no 
equivalent standards for EPA Methods 2E, 21, and 25C. However, one VCS 
was identified as an acceptable alternative to EPA Method 3A.
    The VCS ASTM D6522-11, ``Standard Test Method for the Determination 
of Nitrogen Oxides, Carbon Monoxide, and Oxygen Concentrations in 
Emissions from Natural Gas-Fired Reciprocating Engines, Combustion 
Turbines, Boilers, and Process Heaters Using Portable Analyzers,'' is 
an acceptable alternative to EPA Method 3A when used at the wellhead 
before combustion. It is advisable to know the flammability and check 
the lower explosive limit of the flue gas constituents, prior to 
sampling, in order to avoid undesired ignition of the gas. The results 
of ASTM D6522-11 may be used to determine nitrogen oxides and carbon 
monoxide emission concentrations from natural gas combustion at 
stationary sources. This test method may also be used to monitor 
emissions during short-term emission tests or periodically in order to 
optimize process operation for nitrogen oxides and carbon monoxide 
control. The EPA's review, including review of comments for these 15 
methods, is documented in the memorandum, Voluntary Consensus Standard 
Results for Emission Guidelines and Compliance Times for Municipal 
Solid Waste Landfills, 2016, which is available in the docket for the 
2016 MSW Landfills EG (Docket ID Item No. EPA-HQ-OAR-2014-0451-0206).

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

    The EPA believes that this action does not have disproportionately 
high and adverse human health or environmental effects on minority 
populations, low-income populations, and/or indigenous peoples, as 
specified in Executive Order 12898 (59 FR 7629, February 16, 1994). The 
EPA has determined that because this action increases the level of 
environmental protection for all affected populations without having 
any disproportionately high and adverse human health or environmental 
effects on any population, including any minority, low-income, or 
indigenous populations. To the extent that any minority, low-income, or 
indigenous subpopulation is disproportionately impacted by landfill gas 
emissions due to the proximity of their homes to sources of these 
emissions, that subpopulation also stands to see increased 
environmental and health benefit from the emission reductions called 
for by this action. The results of the demographic analysis are 
presented in the EJ Screening Report for Municipal Solid Waste 
Landfills, July 2016, a copy of which is available in the 2016 MSW 
Landfills EG docket (Docket ID Item No. EPA-HQ-OAR-2014-0451-0223).
