 Environmental Protection Agency 40 CFR Part 52
[EPA-R10-OAR-2023-0342: FRL-11155-02-R10]
 AGENCY: Environmental Protection Agency (EPA).
 ACTION: Final rule.
 SUMMARY: The Environmental Protection Agency (EPA) is approving revisions to the Washington State Implementation Plan (SIP) that were submitted on June 22, 2023, by the Department of Ecology in coordination with the Southwest Clean Air Agency (SWCAA). In 2017, the EPA approved a comprehensive update to 
                        *SWCAA 400 General Regulations for Air Pollution Sources*
                         in the SIP, which includes new source review permitting requirements as well as other general requirements for sources regulated under SWCAA's jurisdiction. In this action, the EPA is approving minor updates to SWCAA 400 promulgated since our comprehensive approval in 2017.
 DATES: This final rule is effective October 30, 2023.
 ADDRESSES: The EPA has established a docket for this action under Docket ID 
                        ( print page 67098)

SUPPLEMENTARY INFORMATION: Throughout this document wherever “we” or “our” is used, it means the EPA. I. Background On June 22, 2023, Washington submitted a SIP revision to the EPA. In the submission, Southwest Clean Air Agency (SWCAA) made minor revisions to the general air quality regulations and requested, in coordination with the Washington Department of Ecology, to update the federally approved SIP. On July 31, 2023, we proposed to approve the submission (88 FR 49398). The reasons for our proposed approval are included in the proposal and will not be restated here. The public comment period closed on August 30, 2023. We received no comments on our proposed action and therefore we are finalizing our action as proposed. II. Final Action The EPA is approving and incorporating by reference the regulatory changes to 
                    *SWCAA 400 General Regulations for Air Pollution Sources*
                     submitted by Washington on June 22, 2023.[1]
                    
                     The EPA is also approving a minor, non-substantive change to the Code of Federal Regulations (CFR) at 40 CFR 52.2470(c)—
                    *Table 8*
                     under the applicability subheading to more clearly reflect jurisdiction for issuing permits under the Prevention of Significant Deterioration (PSD) program.

                Appendix A SWCAA Method 9 Visual Opacity Determination Method (establishing test methods for opacity compliance) state effective March 21, 2020. In addition to the regulations approved and incorporated by reference above, the EPA reviews and approves state and local clean air agency submissions to ensure they provide adequate enforcement authority and other general authority to implement and enforce the SIP. However, regulations describing such agency enforcement and other general authority are generally not incorporated by reference so as to avoid potential conflict with the EPA's independent authorities. We are therefore approving the submitted revisions, effective September 10, 2021, to sections 400-230, 400-240, 400-270, and 400-280 in 40 CFR 52.2470(e), 
                    *EPA Approved Nonregulatory Provisions and Quasi-Regulatory Measures.*( print page 67099) III. Incorporation by Reference In this document, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, we are finalizing the incorporation by reference of the Southwest Clean Air Agency regulatory provisions described in section II of this preamble and set forth in the amendments to 40 CFR part 52 in this document. The EPA has made, and will continue to make, these materials generally available through 
                    *https://www.regulations.gov*
                     and at the EPA Region 10 Office (please contact the person identified in the 
                    **FOR FURTHER INFORMATION CONTACT**
                     section of this preamble for more information). Therefore, these materials have been approved by the EPA for inclusion in the SIP, have been incorporated by reference by the EPA into that plan, are fully federally enforceable under sections 110 and 113 of the Clean Air Act as of the effective date of the final rule of the EPA's approval, and will be incorporated by reference in the next update to the SIP compilation.[2] IV. Statutory and Executive Order Reviews Under the Clean Air Act, the Administrator is required to approve a SIP submission that complies with the provisions of the Clean Air 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 Clean Air Act. 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 14094 (88 FR 21879, April 11, 2023);
                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 inExecutive Order 13132 (64 FR 43255, August 10, 1999);
                Is not subject toExecutive Order 13045 (62 FR 19885, April 23, 1997) because it approves a state program;
                Is not a significant regulatory action subject toExecutive Order 13211 (66 FR 28355, May 22, 2001); and
                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 Clean Air Act. Executive Order 12898 (Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations, 59 FR 7629, February 16, 1994) directs Federal agencies to identify and address “disproportionately high and adverse human health or environmental effects” of their actions on minority populations and low-income populations to the greatest extent practicable and permitted by law. The EPA defines environmental justice (EJ) as “the fair treatment and meaningful involvement of all people regardless of race, color, national origin, or income with respect to the development, implementation, and enforcement of environmental laws, regulations, and policies.” The EPA further defines the term fair treatment to mean that “no group of people should bear a disproportionate burden of environmental harms and risks, including those resulting from the negative environmental consequences of industrial, governmental, and commercial operations or programs and policies.” The Southwest Clean Air Agency and the Washington Department of Ecology did not evaluate environmental justice considerations as part of its SIP submittal; the Clean Air Act and applicable implementing regulations neither prohibit nor require such an evaluation. The EPA did not perform an EJ analysis and did not consider EJ in this action. Due to the nature of the action being taken here, this action is expected to have a neutral to positive impact on the air quality of the affected area. Consideration of EJ is not required as part of this action, and there is no information in the record inconsistent with the stated goal of Executive Order 12898 of achieving environmental justice for people of color, low-income populations, and Indigenous peoples. 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 it 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). This action is subject to the Congressional Review Act, and the EPA will submit a rule report to each House of the Congress and to the Comptroller General of the United States. This action is not a “major rule” as defined by 5 U.S.C. 804(2). 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 November 28, 2023. 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). List of Subjects in 40 CFR Part 52 Environmental protection
