[EPA-R09-OAR-2018-0535; FRL-9690-02-R9]


Withdrawal and Partial Approval/Partial Disapproval of Clean Air 
Plans; San Joaquin Valley, California; Contingency Measures for 2008 
Ozone Standards

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is taking final 
action to withdraw the portion of a March 25, 2019 final action 
conditionally approving state implementation plan (SIP) submissions 
from the State of California under the Clean Air Act (CAA or ``Act'') 
to address contingency measure requirements for the 2008 ozone national 
ambient air quality standards (NAAQS or ``standards'') in the San 
Joaquin Valley, California ozone nonattainment area. The SIP 
submissions include the portions of the ``2016 Ozone Plan for 2008 8-
Hour Ozone Standard'' and the ``2018 Updates to the California State 
Implementation Plan'' that address the contingency measure requirement 
for San Joaquin Valley. Simultaneously, the EPA is taking final action 
to partially approve and partially disapprove these SIP submissions. 
These actions are in response to a decision issued by the U.S. Court of 
Appeals for the Ninth Circuit (Association of Irritated Residents v. 
EPA, Ninth Circuit, No. 19-71223, opinion filed August 26, 2021) 
remanding the EPA's conditional approval of the contingency measure SIP 
submissions back to the Agency for further proceedings consistent with 
the decision.

DATES: This final rule is effective on November 2, 2022.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-R09-OAR-2018-0535. All documents in the docket are 
listed on the https://www.regulations.gov

I. Summary of the Proposed Action

    On May 24, 2022, the EPA proposed to withdraw the portion of a 
March 25, 2019 final action conditionally approving SIP submissions 
from the State of California under the CAA to address contingency 
measure requirements for the 2008 ozone NAAQS in the San Joaquin 
Valley, California ozone nonattainment area.\1\ The SIP submissions 
include the portions of the 2016 Ozone Plan for 2008 8-Hour Ozone 
Standard (``2016 Ozone Plan'') and the 2018 Updates to the California 
State Implementation Plan (``2018 SIP Update'') that address the 
contingency measure requirement for San Joaquin Valley. In the same 
rule, the EPA also proposed to partially approve and partially 
disapprove these SIP submissions. Specifically, consistent with a 2021 
decision by the Ninth Circuit remanding the EPA's previous conditional 
approval of the contingency measure element, the EPA proposed to 
disapprove the submissions for failure to meet the contingency measure 
SIP requirements under CAA sections 172(c)(9) and 182(c)(9), except for 
a state measure referred to as the ``Enhanced Enforcement Activities 
Program'' measure for which the EPA proposed approval based on SIP-
strengthening grounds.
---------------------------------------------------------------------------

    \1\ 87 FR 31510. The San Joaquin Valley nonattainment area for 
the 2008 8-hour ozone NAAQS consists of San Joaquin, Stanislaus, 
Merced, Madera, Fresno, Tulare, and Kings counties, and the western 
portion of Kern County.
---------------------------------------------------------------------------

    In our proposed rule, we provided background information on ozone 
and its precursor emissions (i.e., volatile organic compounds and 
oxides of nitrogen), common sources of ozone precursor emissions, and 
health effects associated with elevated ozone levels. We also provided 
background information on the EPA's establishment of the ozone NAAQS, 
including the ozone NAAQS that we established in 2008 (``2008 ozone 
NAAQS''), the SIP submissions that are required under the CAA for areas 
designated as nonattainment for the 2008 ozone NAAQS, and the roles and 
responsibilities of the California Air Resources Board (CARB) and the 
San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD or 
``District'').
    We also discussed the specific SIP submission requirements under 
CAA sections 172(c)(9) and 182(c)(9) for contingency measures. In 
short, contingency measures are additional controls or measures to be 
implemented in the event the area fails to make reasonable further 
progress (RFP) or to attain the NAAQS by the attainment date. Among 
other requirements, contingency measures must be designed so as to be 
implemented prospectively; already-implemented control measures may not 
serve as contingency measures even if they provide emissions reductions 
beyond those needed for any other CAA purpose and should provide for 
emissions reductions approximately equivalent to one year's worth of 
RFP.
    In our proposed rule, we described the State of California's SIP 
submissions for the San Joaquin Valley ``Extreme'' nonattainment area 
for the 2008 ozone NAAQS, including the District's 2016 Ozone Plan and 
the San Joaquin Valley portion of the 2018 SIP Update. We noted that, 
in 2019, the EPA approved the 2016 Ozone Plan and the relevant portion 
of the 2018 SIP Update as meeting all the applicable statutory and 
regulatory requirements for the San Joaquin Valley Extreme 
nonattainment area for the 2008 ozone NAAQS, with the exception of the 
contingency measure requirement.\2\
---------------------------------------------------------------------------

    \2\ 84 FR 3302 (February 12, 2019), corrected at 84 FR 19680 
(May 3, 2019); and 84 FR 11198 (March 25, 2019).
---------------------------------------------------------------------------

    As described further in the proposed rule, the contingency measure 
element of the 2016 Ozone Plan, as modified by the 2018 SIP Update, 
includes the Enhanced Enforcement Activities Program and an evaluation 
of the surplus emissions reductions from already-implemented 
measures.\3\ In addition, the District and CARB made commitments to 
adopt and submit a contingency provision \4\ as part of the District's 
architectural coatings rule within a year of the final conditional 
approval. Once adopted, submitted, and approved, the contingency 
provision in the architectural coatings rule would become a third part 
of the contingency measure element. The EPA estimated that the 
contingency measure, i.e., the contingency provision in the 
architectural coatings rule, would achieve emissions reductions 
equivalent to approximately 9 percent of one year's worth of RFP.
---------------------------------------------------------------------------

    \3\ 83 FR 61346, at 61356 (November 29, 2018). In this context, 
``surplus'' emissions reductions refer to emissions reductions that 
are not needed to meet other SIP requirements, such as the RFP and 
attainment demonstrations.
    \4\ The specific contingency provision that the District 
committed to adopt is the removal of the exemption for architectural 
coatings that are sold in containers with a volume of one liter 
(1.057 quarts) or less, i.e., if triggered by an EPA determination 
of failure to meet an RFP milestone or failure to attain the 2008 
ozone NAAQS by the applicable attainment date. On April 23, 2020, 
CARB submitted the District's architectural coatings rule (SJVUAPCD 
Rule 4601), as amended to include the contingency provision, to the 
EPA as a SIP revision.
---------------------------------------------------------------------------

    As discussed in our proposed rule, we conditionally approved the 
contingency measure element in our March 25, 2019 final rule based on 
the District's and CARB's commitments and found that the one 
contingency measure (i.e., once adopted, submitted, and approved by the 
EPA) would be sufficient for the State and District to meet the 
contingency measure requirement for San Joaquin Valley for the 2008 
ozone NAAQS, notwithstanding expected emissions reductions from the 
measure equivalent to only a fraction of one year's worth of RFP.\5\ In 
our March 25, 2019 final rule, we found the reductions from the one 
contingency measure to be sufficient when considered together with the 
substantial surplus emissions reductions we anticipated to occur in the 
future from already-implemented measures and from other approved 
measures in the plan.\6\ In our March 25, 2019 final rule, we approved 
CARB's Enhanced Enforcement Activities Program measure as a SIP-
strengthening measure rather than as a contingency measure.\7\

    \5\ 84 FR 11198, at 11206 (March 25, 2019).
    \6\ Id.
    \7\ Id.
---------------------------------------------------------------------------

    In our May 24, 2022 proposed rule, we noted that our final 
conditional approval of the contingency measure element was the subject 
of a legal challenge and that, in a 2021 Ninth

[[Page 59690]]

Circuit decision in the Association of Irritated Residents v. EPA case, 
the Court remanded the conditional approval action back to the 
Agency.\8\ In so doing, the Court found that, by taking into account 
the emissions reductions from already-implemented measures to find that 
the contingency measure would suffice to meet the applicable 
requirement, the EPA was circumventing the court's 2016 holding in Bahr 
v. EPA.\9\ The court rejected the EPA's arguments that the Agency's 
approach was grounded in its long-standing guidance and was consistent 
with the court's 2016 Bahr v. EPA decision. With respect to CARB's 
Enhanced Enforcement Activities Program measure, the court upheld the 
EPA's approval of it as SIP-strengthening and held that the measure was 
enforceable according to its terms.
---------------------------------------------------------------------------

    \8\ Association of Irritated Residents v. EPA, 10 F.4th 937 (9th 
Cir. 2021).
    \9\ Bahr v. EPA, 836 F.3d 1218, at 1235-1237 (9th Cir. 2016). 
Under the Bahr holding, contingency measures under CAA sections 
172(c)(9) and 182(c)(9) must be designed so as to be implemented 
prospectively; already-implemented control measures may not serve as 
contingency measures even if they provide emissions reductions 
beyond those needed for any other CAA purpose.
---------------------------------------------------------------------------

    In our May 24, 2022 proposed rule, we found that, if we do not take 
into account surplus emissions reductions, then the one contingency 
measure (the contingency provision in the District's architectural 
coatings rule) must shoulder the entire burden of achieving roughly one 
year's worth of RFP (if triggered) but would only provide approximately 
9 percent of one year's worth of progress. Because the contingency 
measure would not provide reductions roughly equivalent to one year's 
worth of RFP, we found that the conditional approval could no longer be 
supported, and we proposed to withdraw our previous conditional 
approval of the contingency measure element on that basis. For the same 
reasons that justify the proposed withdrawal of the conditional 
approval, we proposed to disapprove the contingency measure element 
except for the Enhanced Enforcement Activities Program measure.
    With respect to the Enhanced Enforcement Activities Program 
measure, in our May 24, 2022 proposed rule, we proposed approval for 
the same reasons that we provided in the March 25, 2019 final rule and 
that were upheld by the Ninth Circuit. Namely, while we find that the 
Enhanced Enforcement Activities Program measure fails to meet the 
requirements for a stand-alone contingency measure, we also find that 
it strengthens the SIP by triggering certain actions, upon a failure to 
meet RFP or a failure to attain by the applicable attainment date, that 
may lead to emissions reductions that would not otherwise be achieved, 
thereby contributing in part to any remedy for an RFP shortfall or 
failure to attain.
    For more background information and a more extensive discussion of 
the rationale for our proposed action, please see our May 24, 2022 
proposed rule.

II. Public Comments and EPA Responses

    Our proposed rule provided for a 30-day comment period during which 
we received one response, which is a letter supporting our proposed 
action.\10\
---------------------------------------------------------------------------

    \10\ Comment letter dated June 22, 2022, from the Association of 
Irritated Residents and the Central California Environmental Justice 
Network, including two exhibits: the American Lung Association's 
report titled ``State of the Air 2022'' and the SJVUAPCD Executive 
Director's report to the SJVUAPCD Governing Board for the June 16, 
2022 Board meeting titled ``Item Number 13: Receive Update on 
Attainment Planning Efforts for Federal Particulate and Ozone 
Standards.''
---------------------------------------------------------------------------

III. Final Action

    For the reasons summarized above and presented in more detail in 
the proposed rule, we are taking final action to withdraw our March 25, 
2019 conditional approval of the contingency measure element of the 
2016 Ozone Plan, as modified by the 2018 SIP Update, for the San 
Joaquin Valley for the 2008 ozone NAAQS. We are also taking final 
action to partially approve and partially disapprove the contingency 
measure element of the 2016 Ozone Plan, as modified by the 2018 SIP 
Update, with respect to the contingency measure requirements under CAA 
sections 172(c)(9) and 182(c)(9). Specifically, we are disapproving the 
contingency measure element except for the Enhanced Enforcement 
Activities Program measure. We are approving the Enhanced Enforcement 
Activities Program measure because, while we find that the Enhanced 
Enforcement Activities Program measure fails to meet the requirements 
for a stand-alone contingency measure, we also find that it strengthens 
the SIP by triggering certain actions, upon a failure to meet RFP or 
failure to attain by the applicable attainment date, that may lead to 
emissions reductions that would not otherwise be achieved, thereby 
contributing in part to any remedy for an RFP shortfall or failure to 
attain.
    Through this final action, we are revising the section of the CFR 
where the California SIP is identified by removing the contingency 
measure element of the 2016 Ozone Plan, as modified by the 2018 SIP 
Update, that we previously approved (conditionally), except for the 
Enhanced Enforcement Activities Program measure.\11\ Lastly, we are 
making a protective finding under the transportation conformity rule 
because, notwithstanding the partial disapproval of the contingency 
measure element, the 2016 Ozone Plan, as modified by the 2018 SIP 
Update, reflects adopted control measures and contains enforceable 
commitments that fully satisfy the emission reduction requirements for 
RFP and attainment for the 2008 ozone NAAQS.\12\
---------------------------------------------------------------------------

    \11\ We are also revising 40 CFR 52.220(c)(514)(ii)(A)(2) to 
clarify that the applicability of CARB's Enhanced Enforcement 
Activities Program measure is limited to San Joaquin Valley and 
limited to the 2008 ozone NAAQS.
    \12\ 40 CFR 93.120(a)(3). Without a protective finding, the 
final disapproval would result in a conformity freeze, under which 
only projects in the first four years of the most recent conforming 
Regional Transportation Plan (RTP) and Transportation Improvement 
Programs (TIP) can proceed. Generally, during a freeze, no new RTPs, 
TIPs, or RTP/TIP amendments can be found to conform until another 
control strategy implementation plan revision fulfilling the same 
CAA requirements is submitted, the EPA finds its motor vehicle 
emissions budget(s) adequate pursuant to Sec.  93.118 or approves 
the submission, and conformity to the implementation plan revision 
is determined. Under a protective finding, the final disapproval of 
the contingency measures element does not result in a transportation 
conformity freeze in the San Joaquin Valley ozone nonattainment area 
and the metropolitan planning organizations may continue to make 
transportation conformity determinations.
---------------------------------------------------------------------------

    As a consequence of the partial disapproval of the contingency 
measure element, within 24 months of the effective date of this action, 
the EPA must promulgate a federal implementation plan under section 
110(c) unless we approve subsequent SIP submissions that correct the 
plan deficiencies. In addition, under 40 CFR 52.35, the offset sanction 
in CAA section 179(b)(2) will be imposed 18 months after the effective 
date of this action, and the highway funding sanction in CAA section 
179(b)(1) will be imposed six months after the offset sanction is 
imposed. A sanction will not be imposed if the EPA determines that a 
subsequent SIP submission corrects the identified deficiencies before 
the applicable deadline.

IV. Statutory and Executive Order Reviews

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

[[Page 59691]]

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. Paperwork Reduction Act

    This action does not impose an information collection burden under 
the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., 
because the partial SIP disapproval action under section 110 and 
subchapter I, part D of the Clean Air Act will not in-and-of itself 
create any new information collection burdens but simply disapproves 
portions of certain state plans submitted for inclusion into the SIP. 
Burden is defined at 5 CFR 1320.3(b).

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act (RFA) generally requires an agency 
to conduct a regulatory flexibility analysis of any rule subject to 
notice and comment rulemaking requirements unless the agency certifies 
that the rule will not have a significant economic impact on a 
substantial number of small entities. Small entities include small 
businesses, small not-for-profit enterprises, and small governmental 
jurisdictions. For purposes of assessing the impacts of this rule on 
small entities, small entity is defined as: (1) a small business as 
defined by the Small Business Administration's (SBA) regulations at 13 
CFR 121.201; (2) a small governmental jurisdiction that is a government 
of a city, county, town, school district or special district with a 
population of less than 50,000; and (3) a small organization that is 
any not-for-profit enterprise which is independently owned and operated 
and is not dominant in its field.
    After considering the economic impacts of this action on small 
entities, I certify that this action will not have a significant impact 
on a substantial number of small entities. This rule does not impose 
any requirements or create impacts on small entities. The partial SIP 
disapproval action under section 110 and subchapter I, part D of the 
Clean Air Act will not in-and-of itself create any new requirements but 
simply disapproves portions of certain state plans submitted for 
inclusion into the SIP. Accordingly, it affords no opportunity for the 
EPA to fashion for small entities less burdensome compliance or 
reporting requirements or timetables or exemptions from all or part of 
the rule. The fact that the Clean Air Act prescribes that various 
consequences (e.g., higher offset requirements) may or will result from 
disapproval actions does not mean that the EPA either can or must 
conduct a regulatory flexibility analysis for this action. Therefore, 
this action will not have a significant economic impact on a 
substantial number of small entities.

D. Unfunded Mandates Reform Act

    This action contains no federal mandates under the provisions of 
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), 2 U.S.C. 
1531-1538 for state, local, or tribal governments or the private 
sector. The EPA has determined that the partial disapproval action does 
not include a federal mandate that may result in estimated costs of 
$100 million or more to either state, local, or tribal governments in 
the aggregate, or to the private sector. This action disapproves 
portions of certain pre-existing plans under state or local law and 
imposes no new requirements. Accordingly, no additional costs to state, 
local, or tribal governments, or to the private sector, result from 
this action.

E. Executive Order 13132, Federalism

    Executive Order 13132, entitled ``Federalism'' (64 FR 43255, August 
10, 1999), requires the EPA to develop an accountable process to ensure 
``meaningful and timely input by State and local officials in the 
development of regulatory policies that have federalism implications.'' 
``Policies that have federalism implications'' is defined in the 
Executive Order to include regulations that have ``substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government.'' This action 
does not have federalism implications. It will not have substantial 
direct effects on the states, on the relationship between the national 
government and the states, or on the distribution of power and 
responsibilities among the various levels of government, as specified 
in Executive Order 13132, because it merely disapproves portions of 
certain state plans for inclusion into the SIP and does not alter the 
relationship or the distribution of power and responsibilities 
established in the Clean Air Act. Thus, Executive Order 13132 does not 
apply to this action.

F. Executive Order 13175, Coordination With Indian Tribal Governments

    This action does not have tribal implications, as specified in 
Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP 
that the EPA is partially approving and partially disapproving would 
not 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, 
and the EPA notes that it will not impose substantial direct costs on 
tribal governments or preempt tribal law. Thus, Executive Order 13175 
does not apply to this action.

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

    The EPA interprets Executive Order 13045 (62 FR 19885, April 23, 
1997) as applying only to those regulatory actions that concern health 
or safety risks, such that the analysis required under section 5-501 of 
the Executive Order has the potential to influence the regulation. This 
action is not subject to Executive Order 13045 because it is not an 
economically significant regulatory action based on health or safety 
risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997). 
This partial SIP disapproval action under section 110 and subchapter I, 
part D of the Clean Air Act will not in-and-of itself create any new 
regulations but simply disapproves portions of certain state plans 
submitted for inclusion into the SIP.

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

    This action is not subject to Executive Order 13211 (66 FR 28355, 
May 22, 2001) because it is not a significant regulatory action under 
Executive Order 12866.

I. National Technology Transfer and Advancement Act

    Section 12(d) of the National Technology Transfer and Advancement 
Act of 1995 (``NTTAA''), Public Law 104-113, 12(d) (15 U.S.C. 272 note) 
directs the EPA to use voluntary consensus standards in its regulatory 
activities unless to do so would be inconsistent with applicable law or 
otherwise impractical. Voluntary consensus standards are technical 
standards (e.g., materials specifications, test methods, sampling 
procedures, and business practices) that are developed or adopted by 
voluntary consensus standards bodies. NTTAA directs the EPA to provide 
Congress, through OMB, explanations when the Agency decides not to use 
available and applicable

[[Page 59692]]

voluntary consensus standards. The EPA believes that this action is not 
subject to requirements of section 12(d) of NTTAA because application 
of those requirements would be inconsistent with the Clean Air Act.

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

    The state did not evaluate environmental justice considerations as 
part of its SIP submittal. There is no information in the record 
inconsistent with the stated goals of Executive Order 12898 of 
achieving environmental justice for people of color, low-income 
populations, and indigenous peoples.

K. Submission to Congress and the Comptroller General

    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).

L. Petitions for Judicial Review

    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by December 2, 2022. 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).)
