40 CFR Part 52

[EPA-R10-OAR-2017-0597; FRL-9986-49-Region 10]


Air Plan Approval; AK: Fine Particulate Matter Infrastructure 
Requirements

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: Whenever the Environmental Protection Agency (EPA) promulgates 
a new or revised National Ambient Air Quality Standard (NAAQS), the 
Clean Air Act (CAA) requires each state to make a State Implementation 
Plan (SIP) submission establishing that the SIP provides for the 
implementation, maintenance, and enforcement of the new or revised 
NAAQS, commonly referred to as infrastructure requirements. The EPA is 
approving the Alaska SIP as meeting specific infrastructure 
requirements for the 1997, 2006, and 2012 fine particulate matter 
(PM2.5) NAAQS.

DATES: This final rule is effective December 27, 2018.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-R10-OAR-2017-0597. All documents in the docket are

I. Background Information

    On March 10, 2016, Alaska submitted a SIP submission to address the 
infrastructure SIP requirements for the 2012 PM2.5 NAAQS, in 
addition to outstanding 1997 and 2006 PM2.5 NAAQS 
infrastructure elements not included in prior submissions. On January 
23, 2018, the EPA proposed to approve the Alaska infrastructure SIP 
submission as meeting the following CAA section 110(a)(2) 
infrastructure elements for the 2012 PM2.5 NAAQS: (A), (B), 
(C), (D)(i)(II), (D)(ii), (E), (F), (H), (J), (K), (L), and (M). We 
also proposed to approve Alaska's March 2016 infrastructure SIP 
submission as meeting the requirements of CAA section 110(a)(2)(G) for 
the 1997, 2006, and 2012 PM2.5 NAAQS (83 FR 3101). The 
public comment period for our proposed action ended on February 22, 
2018.

II. Response to Comments

A. Summary of Comments

    We received 13 adverse comments, all of which appear to be from 
citizens living in North Pole, Alaska, part of the Fairbanks North Star 
Borough (FNSB) nonattainment area.\1\ Commenters expressed concerns 
about the local burn curtailment program and how FNSB implemented the 
program in the nonattainment area this past winter. The program was 
developed by FNSB, submitted to the EPA by the Alaska Department of 
Environmental Conservation (ADEC), and approved by the EPA into the 
Alaska SIP on September 8, 2017, as part of the FNSB Moderate 2006 24-
hour PM2.5 NAAQS nonattainment plan (82 FR 42457).
---------------------------------------------------------------------------

    \1\ See 40 CFR 81.302. A portion of the FNSB is designated 
nonattainment for the 2006 24-hour PM2.5 NAAQS. The 
entire state of Alaska is designated unclassifiable/attainment for 
the 2012 annual PM2.5 NAAQS.
---------------------------------------------------------------------------

    Most of these commenters did not provide details about how their 
concerns warrant approval or disapproval of specific infrastructure SIP 
elements. The EPA does not consider comments on the advisability of 
FNSB control measures in the existing SIP to be within the scope of 
issues subject to public comment in this infrastructure SIP action. The 
provisions in question were previously approved into the SIP as part of 
the FNSB

[[Page 60770]]

Moderate 2006 24-hour PM2.5 NAAQS nonattainment plan, and we 
are not in this action (which approves the Alaska SIP as meeting 
specific infrastructure requirements for the 1997, 2006, and 2012 
PM2.5 NAAQS) revisiting our prior decision. Likewise, 
comments on potential future control measures that have not been 
submitted to the EPA for SIP approval are outside the scope of this 
action.
    One commenter did include detailed information supporting their 
assertion that the EPA should not approve certain infrastructure SIP 
elements in this action, and we have responded to the commenter's 
assertions below.

B. EPA Responses

1. CAA Section 110(a)(2)(A)--Emission Limits
    One commenter stated that CAA section 110(a)(2)(A) requires SIPs to 
include enforceable emission limits, but the ``FNSB has set a standard 
for home wood burning devices that is much more strict than the EPA 
requires.'' The commenter included a link to the ADEC web page 
comparing the EPA's 2015 New Source Performance Standards (NSPS) for 
Residential Wood Heaters to Alaska regulations addressing solid fuel-
fired heating device emission standards, specifically, regulations set 
forth in Alaska Administrative Code (AAC) at 18 AAC 50.077 and 18 AAC 
50.079.\2\ The commenter alleged that the Alaska standards are more 
stringent than the EPA's NSPS and concluded that the Alaska standards 
are, therefore, an unenforceable emission limit under CAA section 
110(a)(2)(A).
---------------------------------------------------------------------------

    \2\ http://burnwise.alaska.gov/standards.htm.
---------------------------------------------------------------------------

    The EPA disagrees with this comment for a number of reasons. First, 
CAA section 110(a)(2)(A) requires SIPs to include enforceable emission 
limitations and other control measures, means, or techniques (including 
economic incentives such as fees, marketable permits, and auctions of 
emissions rights), as well as schedules and timetables for compliance, 
as may be necessary or appropriate to meet the applicable requirements 
of the CAA. In the context of an infrastructure SIP submission for a 
new or revised NAAQS, however, the EPA is not evaluating the 
substantive merit of existing control measures in the SIP, unlike the 
evaluation of such measures in a nonattainment plan SIP submission. For 
an infrastructure SIP submission, the EPA interprets section 
110(a)(2)(A) to require states to make a submission that identifies the 
existing measures in their SIPs that are relevant to the NAAQS at 
issue, as the first step in their planning for implementation of a new 
or revised NAAQS.\3\ These infrastructure SIP submissions should 
identify enforceable control measures as part of the demonstration that 
the State has the available tools and authority to develop and 
implement plans to attain and maintain the NAAQS.
---------------------------------------------------------------------------

    \3\ See August 14, 2015, final rule approving Indiana and Ohio 
infrastructure SIPs (80 FR 48733 at pages 48737-48738).
---------------------------------------------------------------------------

    The EPA's longstanding position is that infrastructure SIPs are 
statewide planning SIPs to implement, maintain, and enforce a NAAQS in 
general, and are not detailed attainment and maintenance plans for an 
individual area of a state.\4\ Infrastructure SIPs are due within three 
years of adoption or revision of a particular NAAQS, according to CAA 
sections 110(a)(1) and (2). The separate nonattainment plan SIP 
submissions to address the emission limits and other control measures 
needed to attain a particular NAAQS in an area designated nonattainment 
are due on a separate schedule, pursuant to CAA section 172 and the 
various pollutant-specific subparts 2 through 5 of part D.\5\
---------------------------------------------------------------------------

    \4\ See detailed discussion of the scope of infrastructure SIP 
actions in the July 20, 2016, proposed rule on the Alaska SIP with 
respect to infrastructure requirements (81 FR 47103, at page 47104).
    \5\ See 2013 infrastructure guidance: Stephen D. Page, Director, 
Office of Air Quality Planning and Standards. ``Guidance on 
Infrastructure State Implementation Plan (SIP) Elements under Clean 
Air Act Sections 110(a)(1) and 110(a)(2).'' Memorandum to EPA Air 
Division Directors, Regions 1-10, September 13, 2013.
---------------------------------------------------------------------------

    Second, the EPA disagrees because the comment is not germane to 
this action on the State's infrastructure SIP submission. The 
commenter's assertions focus on control measures already established by 
the State in 18 AAC 50.077 and 18 AAC 50.079 to attain the 2006 24-hour 
PM2.5 NAAQS in the FNSB nonattainment area. On September 8, 
2017, the EPA approved 18 AAC 50.077 as an appropriate control measure 
for the area and we are not revisiting our prior decision.\6\ The EPA 
already addressed the substance and validity of the control measures, 
and the need for such measures to help reach attainment of the NAAQS in 
the FNSB area in that prior action. We note that the standards in 18 
AAC 50.079 have not been submitted by Alaska to the EPA and are 
therefore outside the scope of this action.
---------------------------------------------------------------------------

    \6\ See September 8, 2017, final rule (82 FR 42457) and February 
2, 2017, proposed rule (82 FR 9035 at pages 9045-9046).
---------------------------------------------------------------------------

    Third, the EPA does not agree that it is appropriate to compare the 
stringency of an NSPS with the stringency of other forms of control 
measures that may be necessary for a given source category. The NSPS 
for woodstoves focuses on emission reductions achievable through 
redesign of new woodstoves to reduce emissions. By contrast, potential 
SIP control measures can, and may be required to, achieve emission 
reductions by other means such as requirements to burn dry wood, 
opacity standards, curtailment programs, or other mechanism to reduce 
emissions from both new and existing sources, perhaps over and above 
what may result from the NSPS alone. The commenter incorrectly presumes 
that an NSPS is necessarily the proper point of comparison for the 
validity of SIP provisions to address emissions from woodstoves.
    Fourth, the EPA disagrees with the premise that states cannot 
regulate a source category more stringently than may be required in a 
Federal regulation. In enacting section 110 of the CAA, Congress gave 
states the lead in developing plans to implement, maintain, and enforce 
the NAAQS. The EPA's role is to review and approve state choices if 
they meet the minimum criteria of the CAA. See 42 U.S.C. 7410(k) and 40 
CFR 52.02(a). There is nothing in the CAA that prevents SIP provisions 
from being more stringent than Federal NSPS standards. To the contrary, 
CAA section 116 explicitly authorizes states to regulate sources more 
stringently than the EPA does through Federal regulations. More 
importantly, states have the obligation to regulate sources as 
necessary to meet nonattainment area plan stringency requirements, such 
as reasonably- and best available control measures, and the obligation 
to regulate sources as necessary to attain the NAAQS in a given 
nonattainment area. Thus, the fact that 18 AAC 50.077 may be more 
stringent than the NSPS for home heating devices does not make it 
unenforceable.
    Finally, we note that Alaska's infrastructure SIP submission 
established that the State has a program for implementation, 
maintenance, and enforcement of the 2012 PM2.5 NAAQS that 
covers a range of relevant sources of emissions. As discussed in the 
proposed action, Alaska regulates emissions of PM2.5 and its 
precursors through the SIP-approved major and minor new source review 
(NSR) permitting programs, most recently updated on August 28, 2017 (82 
FR 40712). In addition to permitting requirements, Alaska's SIP 
contains other rules that limit particulate matter emissions. These 
rules include incinerator emission standards,

[[Page 60771]]

emission limits for specific industrial processes and fuel burning 
equipment, open burning restrictions, visible emission limits on marine 
vessel emissions, and requirements for installing and operating solid 
fuel-fired devices.
    We continue to find that the Alaska infrastructure SIP submission 
meets the requirements of CAA section 110(a)(2)(A) for purposes of the 
2012 PM2.5 NAAQS and we are finalizing our proposed 
approval. To the extent that additional control measures are necessary 
to meet other requirements, such as control measures necessary to reach 
attainment of the NAAQS in the FNSB nonattainment area in a 
nonattainment plan SIP submission, Alaska and the EPA will address that 
in subsequent actions.
2. CAA Sections 110(a)(2)(B) and (K)--Monitoring and Modeling
    The commenter asserted that the regulatory monitor at Hurst Road in 
North Pole, Alaska ``routinely records the highest levels of 
PM2.5 seen in the nation, while devices nearby record normal 
levels of PM2.5.'' The commenter concluded that ``the FNSB 
is using faulty air quality parameters'' that are being used to dictate 
the strategy for the nonattainment area and that the State has failed 
to meet CAA sections 110(a)(2)(B) and (K).
    The EPA disagrees that the relative levels of ambient 
PM2.5 at monitors in the FNSB affects the approvability of 
the infrastructure SIP submission. In the context of an infrastructure 
SIP submission, the EPA interprets CAA section 110(a)(2)(B) to require 
states to have SIP provisions to provide for the establishment and 
operation of ambient air quality monitors, collecting and analyzing 
ambient air quality data, and making these data available to the EPA 
upon request. In our proposed action, we stated that Alaska has a 
comprehensive air quality monitoring plan, originally approved by the 
EPA into the Alaska SIP on April 15, 1981 (46 FR 21994). We also 
determined that the plan includes statutory and regulatory authority to 
establish and operate an air quality monitoring network, including 
PM2.5 monitoring (January 23, 2018; 83 FR 3101, at page 
3103). In practice, Alaska operates a comprehensive PM2.5 
monitoring network, compiles and analyzes collected data, and submits 
the data to the EPA's Air Quality System on a quarterly basis.
    With respect to monitor siting, Alaska regularly assesses the 
adequacy of the State monitoring network and submits that assessment to 
the EPA for review. The most recent Alaska network assessment is 
available at http://dec.alaska.gov/air/air-monitoring/network-assessments. The fact that a single monitor records ambient 
PM2.5 values higher than monitors in surrounding areas does 
not establish that the monitoring data is inaccurate. The EPA's network 
design criteria are found in Appendix D to 40 CFR part 58. The fine 
particulate matter design criteria for state and local air monitors, at 
paragraph 4.7 of the Appendix, directs states to appropriately monitor 
the area of maximum concentration. We continue to find that Alaska has 
met the infrastructure SIP monitoring requirement of CAA section 
110(a)(2)(B) for the 2012 PM2.5 NAAQS and we are finalizing 
our proposed approval with respect to this requirement.
    In the context of an infrastructure SIP submission, the EPA 
interprets CAA section 110(a)(2)(K) to require that SIPs provide for 
the performance of air quality modeling as may be prescribed by the 
EPA, and the submission of that modeling data by states to the EPA as 
required or upon request. In our proposed action, we stated that 
Alaska's SIP meets the infrastructure SIP requirements for modeling 
because, as stated in the submission, Alaska incorporates the EPA's 
Guideline on Air Quality Models into the SIP at 18 AAC 50.040 and 
requires its use based on 18 AAC 50.215 Ambient Air Quality Analysis 
Methods.
    Beyond alleging that ``the FNSB is using faulty air quality 
parameters,'' the commenter did not specify why they felt the Alaska 
SIP failed to meet CAA section 110(a)(2)(K) for the 2012 
PM2.5 NAAQS. We continue to find that the Alaska SIP 
provides the necessary authority to perform required air quality 
modeling and to submit that data to the EPA.\7\ Therefore, we are 
finalizing our proposed approval of the infrastructure SIP submission 
with respect to CAA section 110(a)(2)(K) for the 2012 PM2.5 
NAAQS.

Elements under Clean Air Act Sections 110(a)(1) and 110(a)(2).'' 
Memorandum to EPA Air Division Directors, Regions 1-10, September

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

3. CAA section 110(a)(2)(C)--Enforcement
    The commenter alleged that the FNSB cannot enforce wood burning 
curtailment as a practical matter and pointed to public statements that 
the FNSB has found ``very low compliance'' but has issued ``only one 
citation.'' The commenter concluded that the program is unenforceable 
and that the State has failed to meet CAA section 110(a)(2)(C) with 
respect to enforcement.
    In the context of an infrastructure SIP submission, the EPA 
interprets CAA section 110(a)(2)(C) to require, among other things, a 
program providing for enforcement of all SIP measures. As stated in the 
infrastructure SIP submission, Alaska statute provides ADEC authority 
to enforce air quality regulations, permits, and orders promulgated 
pursuant to AS 46.03 and AS 46.14. ADEC staffs and maintains an 
enforcement program to ensure compliance with SIP requirements. ADEC 
has emergency order authority when there is an imminent or present 
danger to health or welfare or potential for irreversible or 
irreparable damage to natural resources or the environment. Enforcement 
cases may be referred to the State Department of Law. Therefore, we 
proposed to approve the Alaska SIP as meeting the requirements of CAA 
section 110(a)(2)(C) related to enforcement for the 2012 
PM2.5 NAAQS.
    The commenter asserted that the FNSB burn curtailment program is 
unenforceable and that the EPA should therefore disapprove the 
infrastructure SIP submission with respect to CAA section 110(a)(2)(C). 
The EPA disagrees that the amount or type of enforcement of a SIP 
provision necessarily affects the approvability of an infrastructure 
SIP submission. In the context of evaluating an infrastructure SIP 
submission, the EPA is focused upon the facial sufficiency of the 
State's SIP and does not evaluate issues related to the State's 
implementation of the SIP. The EPA has other authority to take action, 
in the event the State is actually failing to implement its SIP, such 
as the issuance of a finding of failure to implement or a SIP call. In 
this instance, the comment also relates to the State's exercise of 
enforcement discretion, rather than to the facial sufficiency of the 
State's SIP with respect to enforcement authority.
    As stated in our proposal, the SIP contains the required statutory 
authority to enforce air quality regulations, permits, and orders.\8\ 
We continue to find that the Alaska SIP meets the infrastructure 
requirements of CAA section 110(a)(2)(C) for the 2012 PM2.5 
NAAQS and we are finalizing our proposed approval.
---------------------------------------------------------------------------

    \8\ January 23, 2018; 83 FR 3101, pages 3103-3104.
---------------------------------------------------------------------------

4. CAA section 110(a)(2)(G)--Emergency Episodes
    The commenter stated that ``the emergency episode plan for FNSB is 
not sustainable'' and specifically referred to a voter initiative to 
remove wood

[[Page 60772]]

burning from FNSB regulatory oversight. The commenter also alleged that 
the FNSB is using the SIP emergency episode plan ``as a surrogate for 
its own desires to limit wood burning.'' The commenter therefore argued 
that the State has failed to meet 110(a)(2)(G) infrastructure 
requirements.
    In the context of an infrastructure SIP submission, the EPA 
interprets CAA section 110(a)(2)(G) to require two things: (1) States 
must have general emergency authority to address activities causing 
imminent and substantial endangerment to public health, and (2) if the 
area has high ambient PM2.5 concentrations in the past, a 
contingency plan in their SIPs to achieve emission reductions in the 
event of an emergency episode.
    In the March 10, 2016, infrastructure submission, with respect to 
general emergency authority, Alaska cited to Alaska Statute (AS) 
46.03.820 Emergency powers, which provides ADEC with emergency order 
authority where there is an imminent or present danger to the health or 
welfare of the people of the state or would result in or be likely to 
result in irreversible or irreparable damage to the natural resources 
or environment. In addition, with respect to a contingency plan to 
achieve emission reductions in the event of an emergency episode, 
Alaska referenced State-wide emergency episode rules at 18 AAC 50.246 
Air Quality Episodes and Advisories for PM2.5. These rules 
authorize ADEC to declare an air alert, air warning, or air advisory to 
notify the public and prescribe and publicize curtailment action, 
including imposition of restrictions on open burning under 18 AAC 
50.065 and limits on visible emissions from solid fuel-fired heating 
devices under 18 AAC 50.075. The submission also noted that the FNSB 
developed a local emergency episode plan for PM2.5 
applicable in the FNSB area, and the State adopted the plan into the 
Alaska SIP at 18 AAC 50.030.
    On January 23, 2018, the EPA proposed to find that AS 46.03.820 
Emergency powers provides emergency order authority comparable to CAA 
section 303.\9\ We also proposed to find that Alaska's State-wide 
emergency episode rules are consistent with the requirements of 40 CFR 
part 51 subpart H for PM2.5 (prevention of air pollution 
emergency episodes, sections 51.150 through 51.153).\10\ These State-
wide, SIP-approved regulations and statute continue to meet the CAA 
section 110(a)(2)(G) emergency episode infrastructure requirements. 
Therefore, we are finalizing our proposed approval of the Alaska SIP as 
meeting CAA section 110(a)(2)(G) for the 1997, 2006, and 2012 
PM2.5 NAAQS.

most recently approved by the EPA on September 8, 2017 (82 FR 
40712).
---------------------------------------------------------------------------

III. Final Action

    We are approving the Alaska SIP as meeting the following CAA 
section 110(a)(2) infrastructure elements for the 2012 PM2.5 
NAAQS: (A), (B), (C), (D)(i)(II), (D)(ii), (E), (F), (H), (J), (K), 
(L), and (M). We are also approving the Alaska SIP as meeting CAA 
section 110(a)(2)(G) for the 1997, 2006, and 2012 PM2.5 
NAAQS. This action is being taken under section 110 of the CAA.

IV. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the CAA and applicable 
federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in 
reviewing SIP submissions, the EPA's role is to approve state choices, 
provided that they meet the criteria of the CAA. Accordingly, this 
action merely approves state law as meeting federal requirements and 
does not impose additional requirements beyond those imposed by state 
law. For that reason, this action:
     Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
     is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866;
     does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
     is certified as not having a significant economic impact 
on a substantial number of small entities under the Regulatory 
Flexibility Act (5 U.S.C. 601 et seq.);
     does not contain any unfunded mandate or significantly or 
uniquely affect small governments, as described in the Unfunded 
Mandates Reform Act of 1995 (Public Law 104-4);
     does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
     is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
     is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
     is not subject to requirements of Section 12(d) of the 
National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 
note) because application of those requirements would be inconsistent 
with the CAA; and
     does not provide the EPA with the discretionary authority 
to address, as appropriate, disproportionate human health or 
environmental effects, using practicable and legally permissible 
methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).
    The SIP is not approved to apply on any Indian reservation land or 
in any other area where the EPA or an Indian tribe has demonstrated 
that a tribe has jurisdiction. In those areas of Indian country, the 
rule does not have tribal implications and it will not impose 
substantial direct costs on tribal governments or preempt tribal law as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. The EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the CAA, petitions for judicial review 
of this action must be filed in the United States Court of Appeals for 
the appropriate circuit by January 28, 2019. Filing a petition for 
reconsideration by the Administrator of this final rule does not affect 
the finality of this action for the purposes of judicial review nor 
does it extend the time within which a petition for judicial review may 
be filed, and shall not postpone the effectiveness of such rule or 
action. This action may not be challenged later in proceedings to 
enforce its requirements. See section 307(b)(2).
