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,
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.
PADEP's February 27, 2020 submittal fulfills Pennsylvania's obligation to submit a second maintenance plan and addresses each of the five necessary elements.
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 
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.
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 Start Printed Page 24509contingency 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).)
