40 CFR Parts 52

[EPA-R09-OAR-2020-0534; FRL-10020-36-Region 9]


Approval and Promulgation of Air Quality State Implementation 
Plans; California; Plumas County; Moderate Area Plan for the 2012 PM2.5 
NAAQS

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action to approve a state implementation plan (SIP) revision submitted 
by the State of California to address Clean Air Act (CAA or ``Act'') 
requirements for the 2012 annual fine particulate matter 
(PM2.5) national ambient air quality standard (NAAQS or 
``standard'') in the Plumas County Moderate PM2.5 
nonattainment area (``Portola nonattainment area''). The submitted SIP 
revision is the State's ``Proposed Portola PM2.5 Plan 
Contingency Measure SIP Submittal'' (``PM2.5 Plan 
Revision''), which includes a revised City of Portola ordinance 
regulating PM2.5 emission sources and the State's 
demonstration that this submission meets the Moderate area contingency 
measure requirement for the 2012 annual PM2.5 NAAQS in the 
Portola nonattainment area. The EPA is also taking final action to 
approve the contingency measure element of the Moderate area attainment 
plan for the Portola nonattainment area, as revised and supplemented by 
the PM2.5 Plan Revision.

DATES: This rule is effective on April 2, 2021.

I. Background

    On January 15, 2013, the EPA strengthened the primary annual NAAQS 
for particulate matter with a diameter of 2.5 microns or less by 
lowering the level from 15.0 micrograms per cubic meter ([mu]g/m\3\) to 
12.0 [mu]g/m\3\ (``2012 PM2.5 NAAQS'').\1\ The EPA 
established this standard after considering substantial evidence from 
numerous health studies demonstrating that serious health effects are 
associated with exposures to PM2.5 concentrations above 
these levels.
---------------------------------------------------------------------------

    \1\ 78 FR 3086 and 40 CFR 50.18. Unless otherwise noted, all 
references to the PM2.5 NAAQS in this notice are to the 
2012 annual NAAQS of 12.0 [mu]g/m\3\ codified at 40 CFR 50.18.
---------------------------------------------------------------------------

    Epidemiological studies have shown statistically significant 
correlations between elevated levels of PM2.5 (particulate 
matter with a diameter of 2.5 microns or less) and premature mortality. 
Other important health effects associated with PM2.5 
exposure include aggravation of respiratory and cardiovascular disease, 
changes in lung function, and increased respiratory symptoms. 
Individuals particularly sensitive to PM2.5 exposure include 
older adults, people with heart and lung disease, and children.\2\ 
PM2.5 can be emitted directly into the atmosphere as a solid 
or liquid particle (``primary PM2.5'' or ``direct 
PM2.5'') or can be formed in the atmosphere as a result of 
various chemical reactions among precursor pollutants such as nitrogen 
oxides, sulfur oxides, volatile organic compounds, and ammonia 
(``secondary PM2.5'').\3\

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

    Following promulgation of a new or revised NAAQS, the EPA is 
required by CAA section 107(d) to designate areas throughout the nation 
as attaining or not attaining the NAAQS. The EPA designated and 
classified the Portola nonattainment area as ``Moderate'' nonattainment 
for the 2012 annual PM2.5 standards based on ambient 
monitoring data that showed the area was above 12.0 [mu]g/m\3\ for the 
2011-2013 monitoring period.\4\ For the 2011-2013 period, the annual 
PM2.5 design value for the Portola nonattainment area was 
12.8 [mu]g/m\3\ based on monitored readings at the 161 Nevada Street 
and 420 Gulling Street monitors.\5\
---------------------------------------------------------------------------

    \4\ 80 FR 2206 (January 15, 2015).
    \5\ From 2000 through early 2013, the Portola PM2.5 
monitoring site was located at 161 Nevada Street. In 2013, the site 
was relocated to 420 Gulling Street.
---------------------------------------------------------------------------

    The Portola nonattainment area includes the City of Portola 
(``Portola''), which has a population of approximately 2,100 and is 
located at an elevation of 4,890 feet in an intermountain basin 
isolated by rugged mountains. For a precise description of the 
geographic boundaries of the Portola nonattainment area, see 40 CFR 
81.305.
    The local air district with primary responsibility for developing a 
plan to attain the 2012 annual PM2.5 NAAQS in this area is 
the Northern Sierra Air Quality Management District (NSAQMD or 
``District''). The District worked with the California Air Resources 
Board (CARB) in preparing the PM2.5 Plan Revision. Under 
state law, authority for regulating sources under state jurisdiction in 
the Portola nonattainment area is split between the District, which has 
responsibility for regulating stationary and most area sources, and 
CARB, which has responsibility for regulating most mobile sources.
    On February 28, 2017, California submitted the ``Portola Fine 
Particulate Matter (PM2.5) Attainment Plan'' (``Portola 
PM2.5 Plan'') to address the CAA's Moderate area 
requirements for the 2012 annual PM2.5 NAAQS in the Portola 
nonattainment area. On March 25, 2019, the EPA fully approved the 
Portola PM2.5 Plan, except for the contingency measure 
element.\6\ As part of the attainment control strategy, the Portola 
PM2.5 Plan relies on ``Ordinance No. 344: An Ordinance of 
the City of Portola, County of Plumas Amending Chapter 15.10 of the 
City of Portola Municipal Code Providing for Regulation of Wood Stoves 
and Fireplaces'' (``City Ordinance No. 344'') to achieve direct 
PM2.5 emission reductions necessary for attainment by

[[Page 12264]]

the December 31, 2021 attainment date. The EPA approved City Ordinance 
No. 344 into the SIP on March 5, 2018.\7\ The attainment control 
strategy in the Portola PM2.5 Plan also relies on an 
enforceable state commitment to implement an incentive grant program 
called the ``Greater Portola Woodstove Change-out Program 2016'' 
(``Wood Stove Program'') during the 2016 to 2021 period to fund the 
replacement of uncertified wood stoves with newer, EPA-certified 
devices and to educate residents on proper ways to store and burn wood. 
The EPA approved the Wood Stove Program into the SIP on April 2, 
2018.\8\

    On October 28, 2020, CARB submitted ``Ordinance No. 359: An 
Ordinance of the City of Portola, County of Plumas Amending Chapter 
15.10 of the City of Portola Municipal Code Providing for Regulation of 
Wood Stoves and Fireplaces and the Prohibition of the Open Burning of 
Yard Waste'' (``City Ordinance No. 359''), together with a document 
entitled ``Proposed Portola PM2.5 Plan Contingency Measure 
SIP Submittal,'' October 16, 2020 (hereafter ``CARB Staff Report''), to 
the EPA with a request for approval into the SIP through the EPA's 
parallel processing procedures in 40 CFR part 51, appendix V, section 
2.3.\9\ We refer to this submission of City Ordinance No. 359 and the 
CARB Staff Report together as the ``Proposed PM2.5 Plan 
Revision.'' The Proposed PM2.5 Plan Revision contains, among 
other things, a contingency measure in City Ordinance No. 359 that 
revises and supplements the contingency measure element of the Portola 
PM2.5 Plan.\10\

Officer, CARB, to John Busterud, Regional Administrator, EPA Region

No. 344 in the SIP with City Ordinance No. 359. NSAQMD, Resolution 
2020-09 (October 26, 2020).
---------------------------------------------------------------------------

    On December 3, 2020, the EPA proposed to approve the Proposed 
PM2.5 Plan Revision, through parallel processing, and to 
approve the contingency measure element of the Portola PM2.5 
Plan, as revised and supplemented by the Proposed PM2.5 Plan 
Revision.\11\ Specifically, the EPA proposed to find that the 
contingency measure element of the Portola PM2.5 Plan, as 
revised and supplemented by the Proposed PM2.5 Plan 
Revision, would satisfy the requirements for contingency measures in 
CAA section 172(c)(9) and 40 CFR 51.1014 for purposes of the 2012 
PM2.5 NAAQS in the Portola nonattainment area. Our proposed 
approval was contingent upon the State's submission of the final, 
adopted PM2.5 Plan Revision in time for the EPA to finalize 
this action by March 1, 2021, our court-ordered deadline for taking 
final action on the contingency measure element of the Portola 
PM2.5 Plan.\12\ The EPA also proposed to find that the 
requirement for contingency measures to address a failure to meet a 
reasonable further progress (RFP) requirement for the 2019 RFP 
milestone year was moot as applied to the Portola nonattainment area, 
because the State and District had adequately demonstrated that the 
emission reductions needed for RFP had been achieved and that the 
Portola nonattainment area had met its 2019 quantitative milestone. 
Finally, the EPA proposed to approve a new prohibition on the open 
burning of yard waste and related provisions in City Ordinance No. 359 
that would strengthen the SIP, excluding paragraph 15.10.060 B. and 
sections 15.10.100 and 15.10.110 regarding penalties and 
violations.\13\

PM2.5 Plan Revision to the EPA as a revision to the 
California SIP.\14\ The SIP submission includes evidence that the State 
provided adequate public notice and an opportunity for a public 
hearing, consistent with the EPA's implementing regulations in 40 CFR 
51.102.

II. Public Comments and EPA Responses

    The EPA's proposed action provided a 30-day public comment period 
that ended on January 4, 2021. During this period, the EPA received one 
anonymous comment that does not articulate any issue.\15\ We do not 
respond to this comment because it fails to identify any issue that is 
germane to the EPA's action.
---------------------------------------------------------------------------

    \15\ The comment is available in the docket for this rulemaking 
at https://www.regulations.gov/document?D=EPA-R09-OAR-2020-0534-0028.
---------------------------------------------------------------------------

III. Final Action

    For the reasons discussed in detail in the proposed rule and 
summarized herein, under CAA section 110(k)(3), the EPA is taking final 
action to approve the PM2.5 Plan Revision and to approve the 
contingency measure element of the Portola PM2.5 Plan, as 
revised and supplemented by the PM2.5 Plan Revision, as 
meeting the contingency measure requirements of CAA section 172(c)(9) 
and 40 CFR 51.1014 for the 2012 annual PM2.5 NAAQS in the 
Portola nonattainment area. The EPA is also determining that the 
requirement for RFP contingency measures for the 2019 milestone date is 
moot as applied to the Portola nonattainment area, because the State 
and District have adequately demonstrated that the emission reductions 
needed for RFP have been achieved and that the 2019 quantitative 
milestone has been met in the Portola nonattainment area.
    Finally, the EPA is approving new provisions in City Ordinance No. 
359 concerning open burning of yard wastes and other debris, including 
related definitions and exemptions. These provisions strengthen the SIP 
and are consistent with CAA requirements regarding enforceability and 
SIP revisions. At the State's and District's request, we are not acting 
on paragraph 15.10.060 B., section 15.10.100, or section 15.10.110 of 
City Ordinance No. 359.

IV. Incorporation by Reference

    In this rule, the EPA is finalizing regulatory text that includes 
incorporation by reference. In accordance with requirements of 1 CFR 
51.5, the EPA is finalizing the incorporation by reference of the City 
of Portola ordinance described in the amendments to 40 CFR part 52 set 
forth below. The EPA has made, and will continue to make, these 
documents available through www.regulations.gov and at the EPA Region 
IX Office (please contact the person identified in the FOR FURTHER 
INFORMATION CONTACT section of this preamble for more information).

V. Statutory and Executive Order Reviews

    Under the CAA, the Administrator is required to approve a SIP 
submission that complies with the provisions of the Act 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, or conditionally approves, state plans as 
meeting federal

[[Page 12265]]

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);
     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 (Pub. L. 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 practical and legally permissible methods, 
under Executive Order 12898 (59 FR 7629, February 16, 1994).
    In addition, 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 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 May 3, 2021. 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)).
