Environmental Protection Agency (EPA).
The Environmental Protection Agency (EPA) is taking final action to approve portions of the Kentucky infrastructure State Implementation Plan (SIP) submission for the 2015 8-hour ozone National Ambient Air Quality Standards (NAAQS) submitted to EPA in a letter dated January 11, 2019. Whenever EPA promulgates a new or revised NAAQS, the Clean Air Act (CAA or Act) requires that each state adopt and submit a SIP submission to establish that the state's SIP meets infrastructure requirements for the implementation, maintenance, and enforcement of each such NAAQS. Specifically, EPA is taking final action to approve portions of the Kentucky infrastructure SIP submission that address the prevention of significant deterioration (PSD) and modeling requirements for the 2015 8-hour ozone NAAQS.
This rule is effective October 2, 2020.

I. Background and Overview
On October 1, 2015, EPA promulgated revised primary and secondary NAAQS for ozone, revising the 8-hour ozone standards from 0.075 parts per million (ppm) to a new more protective level of 0.070 ppm. See 80 FR 65292 (October 26, 2015). Pursuant to section 110(a)(1) of the CAA, states are required to submit SIP revisions meeting the applicable requirements of section 110(a)(2) within three years after promulgation of a new or revised NAAQS or within such shorter period as EPA may prescribe. Section 110(a)(2) requires states to address basic SIP elements such as requirements for monitoring, basic program requirements, and legal authority that are designed to assure attainment and maintenance of the NAAQS. This particular type of SIP is commonly referred to as an “infrastructure SIP.” States were required to submit such SIP revisions for the 2015 8-hour ozone NAAQS to EPA no later than October 1, 2018.
As explained in a notice of proposed rulemaking (NPRM) published on July 6, 2020 (85 FR 40165), Kentucky cites to several regulations 
to demonstrate that their respective SIPs meet the PSD-related requirements of sections 110(a)(2)(C), 110(a)(2)(D)(i)(II) (Prong 3),
110(a)(2)(J), and 110(a)(2)(K). In addition to the regulations approved into the SIP, a state may also rely on EPA's January 17, 2017 (82 FR 5182), final rulemaking entitled, “Revisions to the Guideline on Air Quality Models: Enhancements to the AERMOD Dispersion Modeling System and Incorporation of Approaches To Address Ozone and Fine Particulate Matter” (also referred to as the 2017 Guideline) 
to satisfy the modeling requirements of Section 110(a)(2)(K). On February 4, 2020, the Commonwealth of Kentucky submitted a letter to EPA to demonstrate that its existing SIP-approved regulations provide the state with the authority to integrate and implement the requirements and recommendations of the current version of EPA's 2017 Guideline. In its February 4, 2020, letter, the Commonwealth clarified that, pursuant to 401 KAR 50:040 and 401 KAR 51:017, the Commonwealth has the authority to use Start Printed Page 54508alternative modeling, and that modeling based on the Guideline, as published on January 17, 2017, is the most appropriate.
EPA has evaluated Kentucky's January 11, 2019, submittal 
and the February 4, 2020, letter and is making the determination that Kentucky has demonstrated that it has the authority to use the 2017 Guideline, and notes that the February 4, 2020, letter includes KY DAQ's determination that the 2017 Guideline is most appropriate for use. Accordingly, EPA is taking final action to approve Kentucky's use of the 2017 Guideline as outlined in KY DAQ's February 4, 2020, letter and making a finding that Kentucky's infrastructure SIP submission demonstrates that new major sources and major modifications in areas of the Commonwealth designated attainment or unclassifiable for the specified NAAQS are subject to a federally-approved PSD permitting program meeting all the current structural requirements of part C of title I of the CAA to satisfy the infrastructure SIP PSD elements. EPA also concludes that Kentucky's infrastructure SIP submission, supplemented with the February 4, 2020, letter, meets the requirements of 110(a)(2)(C) for the infrastructure requirements for the 2015 8-hour ozone NAAQS.
In the NPRM published on July 6, 2020, EPA proposed approval of Kentucky's infrastructure submission provided on January 11, 2019, for the applicable infrastructure SIP requirements of the 2015 8-hour ozone NAAQS. The NPRM provides additional detail regarding the background and rationale for EPA's action. Comments on the NPRM were due on or before July 27, 2020. EPA did not receive any comments during the comment period.
II. Final Action
EPA is taking final action to approve the portions of Kentucky's January 11, 2019, 2015 8-hour ozone infrastructure SIP submission that address the PSD-related requirements of CAA sections 110(a)(2)(C), 110(a)(2)(D)(i)(II) (prong 3), and 110(a)(2)(J), and modeling requirements related to CAA section 110(a)(2)(K). All other outstanding applicable infrastructure requirements for this SIP submission have been or will be addressed in separate rulemakings.
III. 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. See 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. These actions merely approve state law as meeting Federal requirements and do not impose additional requirements beyond those imposed by state law. For that reason, these actions:
- Are not significant regulatory actions 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);
- Are not Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory actions because SIP approvals are exempted under Executive Order 12866;
- Do not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
- Are 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.);
- Do 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);
- Do not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
- Are not an economically significant regulatory actions based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
- Are not significant regulatory actions subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
- Are 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
- Do 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).
The SIPs subject to these actions are not approved to apply on any Indian reservation land or in any other area where 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 as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), nor will it impose substantial direct costs on tribal governments or preempt tribal law.
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).
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 November 2, 2020. 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).
