SUMMARY: The Environmental Protection Agency (EPA) is approving a state 
implementation plan (SIP) revision submitted by the Commonwealth of 
Pennsylvania. The revision pertains to the Commonwealth's plan, 
submitted by the Pennsylvania Department of Environmental Protection 
(PADEP), for maintaining the 1997 8-hour ozone national ambient air 
quality standard (NAAQS) (referred to as the ``1997 ozone NAAQS'') in 
the Clearfield/Indiana, Pennsylvania area (``Clearfield/Indiana 
Area''). EPA is approving these revisions to the Pennsylvania SIP in 
accordance with the requirements of the Clean Air Act (CAA).

DATES: This final rule is effective on June 7, 2021.

SUPPLEMENTARY INFORMATION:

[[Page 24508]]

I. Background

    On February 9, 2021 (86 FR 8729), EPA published a notice of 
proposed rulemaking (NPRM). In the NPRM, EPA proposed approval of 
Pennsylvania's plan for maintaining the 1997 ozone NAAQS in the 
Clearfield/Indiana Area through April 20, 2029, in accordance with CAA 
section 175A. The formal SIP revision was submitted by PADEP on 
February 27, 2020.

II. Summary of SIP Revision and EPA Analysis

    On March 19, 2009 (74 FR 11674, effective April 20, 2009), EPA 
approved a redesignation request (and maintenance plan) from PADEP for 
the Clearfield/Indiana Area. In accordance with CAA section 175A(b), at 
the end of the eighth year after the effective date of the 
redesignation, the State must also submit a second maintenance plan to 
ensure ongoing maintenance of the standard for an additional 10 years, 
and in South Coast Air Quality Management District v. EPA,\1\ the D.C. 
Circuit held that this requirement cannot be waived for areas, like the 
Clearfield/Indiana Area, that had been redesignated to attainment for 
the 1997 8-hour ozone NAAQS prior to revocation and that were 
designated attainment for the 2008 ozone NAAQS. CAA section 175A sets 
forth the criteria for adequate maintenance plans. In addition, EPA has 
published longstanding guidance that provides further insight on the 
content of an approvable maintenance plan, explaining that a 
maintenance plan should address five elements: (1) An attainment 
emissions inventory; (2) a maintenance demonstration; (3) a commitment 
for continued air quality monitoring; (4) a process for verification of 
continued attainment; and (5) a contingency plan.\2\ PADEP's February 
27, 2020 submittal fulfills Pennsylvania's obligation to submit a 
second maintenance plan and addresses each of the five necessary 
elements.
---------------------------------------------------------------------------

    \1\ 882 F.3d 1138 (D.C. Cir. 2018).
    \2\ ``Procedures for Processing Requests to Redesignate Areas to 
Attainment,'' Memorandum from John Calcagni, Director, Air Quality 
Management Division, September 4, 1992 (Calcagni Memo).
---------------------------------------------------------------------------

    As discussed in the February 9, 2021 NPRM, EPA allows the submittal 
of a limited maintenance plan (LMP) to meet the statutory requirement 
that the area will maintain for the statutory period. Qualifying areas 
may meet the maintenance demonstration by showing that the area's 
design value \3\ is well below the NAAQS and that the historical 
stability of the area's air quality levels indicates that the area is 
unlikely to violate the NAAQS in the future. EPA evaluated PADEP's 
February 27, 2020 submittal for consistency with all applicable EPA 
guidance and CAA requirements. EPA found that the submittal met CAA 
section 175A and all CAA requirements, and proposed approval of the LMP 
for the Clearfield/Indiana Area as a revision to the Pennsylvania SIP. 
Other specific requirements of PADEP's February 27, 2020 submittal and 
the rationale for EPA's proposed action are explained in the NPRM and 
will not be restated here.
---------------------------------------------------------------------------

    \3\ The ozone design value for a monitoring site is the 3-year 
average of the annual fourth-highest daily maximum 8-hour average 
ozone concentrations. The design value for an ozone nonattainment 
area is the highest design value of any monitoring site in the area.
---------------------------------------------------------------------------

III. EPA's Response to Comments Received

    EPA received one comment on the February 9, 2021 NPRM. This comment 
is in the docket for this rulemaking action. A summary of the comment 
and EPA's response are provided herein.
    Comment: The commenter asserts that the LMP should not be approved 
because ``Pennsylvania identifies no actual contingency measures.'' 
According to the commenter, a ``contingency measure is supposed to be a 
known measure that can be quickly implemented by a state in order to 
prevent the violation of the NAAQS.'' The comment asserts that current 
contingency measures are defective because they allegedly will not be 
evaluated and determined until after an exceedance of the NAAQS has 
occurred. The comment claims that EPA is aware Pennsylvania has a 
history of not meeting its CAA requirements on time, and that it can 
take Pennsylvania more than two years to implement a regulation, which 
would be too long to prevent a violation of the NAAQS.
    Response: The commenter asserts that Pennsylvania identifies no 
actual contingency measures because the measures are not yet 
``evaluated'' and ``determined'' and cannot be implemented before a 
violation of the NAAQS occurs. Because Pennsylvania identifies two 
regulatory and six non-regulatory contingency measures in general 
terms, EPA understands the comment's use of the term ``evaluated'' and 
``determined'' must mean something like the specific measures 
identified by PADEP have not been fully promulgated and are not in 
effect at this time. If EPA's understanding is correct, EPA agrees with 
this fact, but does not agree that this has any bearing on the 
approvability of the particular contingency measures or of the overall 
LMP.
    PADEP identifies six non-regulatory measures and two regulatory 
measures. The two regulatory measures are ``additional controls'' on 
consumer products and portable fuel containers. The six non-regulatory 
measures are: Voluntary diesel engine ``chip reflash;'' diesel retrofit 
for public or private local onroad or offroad fleets; idling reduction 
technology for Class 2 yard locomotives; idling technologies or 
strategies for truck stops, warehouses, and other freight-handling 
facilities; accelerated turnover of lawn and garden equipment; 
additional promotion of alternative fuel for home heating and 
agriculture use. As stated in the Calcagni memo, EPA's long-standing 
interpretation is that contingency measures for maintenance of the 
NAAQS are not required to be fully adopted in order to be approved. The 
commenter refers to a recent court case vacating, among other things, 
the contingency measure provisions in EPA's rule for implementing the 
2015 ozone NAAQS, Sierra Club v. EPA, No. 15-1465 (D.C. Cir. January 
29, 2021). It is possible that the commenter has conflated the 
contingency measure provisions at issue in that case, which pertained 
to attainment plans, and those at issue in this LMP, which pertain to 
maintenance plans. The contingency measure provisions for maintenance 
and attainment are found in two different sections of the CAA, with 
substantially different wording and requirements. The attainment plan 
contingency measures provisions in CAA section 172(c)(9) require that 
the attainment plan have ``specific measures'' that can ``take effect 
in any such case without further action by the State or the 
Administrator'' if the area fails to make reasonable further progress 
or attain the NAAQS. 42 U.S.C. 7502(c)(9). Section 175A of the CAA sets 
forth the contingency measure requirements for maintenance areas. 
Section 175A(d) requires that the maintenance plan contain ``such 
contingency provisions as the Administrator deems necessary to assure 
that the State will promptly correct any violation of the standard 
which occurs after the redesignation of the area as an attainment 
area''. 42 U.S.C. 7505a(d). Unlike section 172(c)(9) there is no 
requirement under section 175A that the contingency measures be set 
forth with specificity or that they be able to take effect without 
further action by EPA or the State.
    With this statutory background in mind, EPA does not agree that the 
plan should be disapproved due to PADEP's alleged inability to 
promulgate a

[[Page 24509]]

contingency measure in sufficient time to avert a violation of the 
NAAQS. As noted previously, CAA section 175A(d) mandates that a 
maintenance plan must contain ``such contingency provisions as the 
Administrator deems necessary to assure that the State will promptly 
correct any violation of the standard which occurs after the 
redesignation of the area as an attainment area'' (emphasis added). The 
statute therefore does not include any requirement that a maintenance 
plan's contingency measures prevent a violation of the NAAQS, but 
rather only that those selected measures be available to address a 
violation of the NAAQS after it already occurs. Pennsylvania also 
elected to adopt a ``warning level response,'' which states that PADEP 
will consider adopting contingency measures if, for two consecutive 
years, the fourth highest eight-hour ozone concentrations at any 
monitor in the area are above 84 parts per billion (ppb). But this 
warning level response is not required under the CAA, and therefore we 
do not agree with the commenter that the plan should be disapproved 
based on the commenter's concern over the timeliness of the warning 
level response implementation.
    Moreover, as a general matter, we do not agree that the schedules 
for implementation of contingency provisions in the LMP are 
insufficient. As noted, the CAA provides some degree of flexibility in 
assessing a maintenance plan's contingency measures--requiring that the 
plan contain such contingency provisions ``as the Administrator deems 
necessary'' to assure that any violations of the NAAQS will be 
``promptly'' corrected. EPA's longstanding guidance for redesignations, 
the Calcagni Memo, also does not provide precise parameters for what 
strictly constitutes ``prompt'' implementation of contingency measures, 
noting that, for purposes of CAA section 175A, ``a state is not 
required to have fully adopted contingency measures that will take 
effect without further action by the state in order for the maintenance 
plan to be approved.'' Calcagni memo at 12. However, the guidance does 
state that the plan should ensure that the measures are adopted 
``expediently'' once they are triggered, and should provide ``a 
schedule and procedure for adoption and implementation, and a specific 
time limit for action by the state.'' Id. We think Pennsylvania's plan, 
which provides specific lists of regulatory and non-regulatory measures 
that Pennsylvania would consider after evaluating and assessing what it 
believed to be the cause of increased ozone concentrations, and the 
specific timeframes it would use to expediently implement the various 
measures, meets the requirements of CAA section 175A.

IV. Final Action

    EPA is approving PADEP's second maintenance plan for the 
Clearfield/Indiana Area for the 1997 ozone NAAQS as a revision to the 
Pennsylvania SIP.

V. Statutory and Executive Order Reviews

A. General Requirements

    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, 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);
     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 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).
    In addition, this rule does not have tribal implications as 
specified by Executive Order 13175 (65 FR 67249, November 9, 2000), 
because the SIP is not approved to apply in Indian country located in 
the State, and EPA notes that it will not impose substantial direct 
costs on tribal governments or preempt tribal law.

B. 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. 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).

C. Petitions for Judicial Review

    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 July 6, 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, approving PADEP's second maintenance plan for the 
Clearfield/Indiana Area for the 1997 ozone NAAQS, may not be challenged 
later in proceedings to enforce its requirements. (See section 
307(b)(2).)
