Air Plan Approval; WA; Southwest Clean Air Agency; Revisions to Excess Emissions, Startup, Shutdown, and General Requirements
AGENCY:
Environmental Protection Agency (EPA).
ACTION:
Final rule.
SUMMARY:
The Environmental Protection Agency (EPA) is approving Washington State Implementation Plan (SIP) revisions to the Southwest Clean Air Agency (SWCAA) air quality regulations submitted by the State of Washington, through the Department of Ecology (Ecology) on June 22, 2023. The revisions were submitted in part to respond to the EPA's June 12, 2015 "SIP call" in which the EPA found a provision in the Washington SIP applicable in the area regulated by SWCAA to be substantially inadequate, providing affirmative defenses that operate to limit the jurisdiction of the Federal court in an enforcement action related to excess emissions during startup, shutdown, and malfunction (SSM) events. The EPA's approval of the SIP revisions to the substantially inadequate provision corrects the SWCAA deficiency identified in the 2015 SSM SIP call and the EPA's January 2022 finding of failure to submit. Washington withdrew some portions of the revisions submitted that were not identified in the 2015 SSM SIP call and therefore the EPA is not approving those withdrawn portions. The EPA proposed to approve this action on December 10, 2024, and received no comments.
DATES:
This final rule is effective June 9, 2025.

I. Background
On December 10, 2024 (89 FR 99177), the EPA proposed to approve State Implementation Plan (SIP) revisions to the Southwest Clean Air Agency (SWCAA) air quality regulations submitted by the State of Washington, through the Department of Ecology (Ecology) on June 22, 2023. In that proposal, we also proposed to determine that the revisions to SWCAA's Rule 400-107, corrects the deficiency with respect to SWCAA that we identified in our June 12, 2015 action entitled "State Implementation Plans: Response to Petition for Rulemaking; Restatement and Update of EPA's SSM Policy Applicable to SIPs; Findings of Substantial Inadequacy; and SIP Calls to Amend Provisions Applying to Excess Emissions During Periods of Startup, Shutdown, and Malfunction" 1 ("2015 SSM SIP call") and our January 12, 2022, Findings of Failure to Submit? 2 (FFS). The remaining SIP revisions submitted with the revised SWCAA Rule 400-107 on June 15, 2023, were not specified in the 2015 SSM SIP call. The reasons for our proposed approval and determination can be found in the proposed action and will not be fully restated here. The public comment period for our proposed approval and determination ended on January 9, 2025, and no comments were received, adverse or otherwise. Therefore, we are finalizing our action as proposed.

II. Final Action
The EPA is approving and incorporating by reference in the Washington SIP the revisions Washington submitted on June 22, 2023, except for those withdrawn by Washington. 3 This action includes revisions to SWCAA Rule 400-107-the provision identified as inconsistent with Clean Air Act (CAA) requirements in our 2015 SSM SIP call-for the SWCAA.
Footnotes:
3 ?See 201_state submittal supplement_SWCAA Partial Withdrawal Request Letter-Ecology.pdf and 202_state submittal supplement_SWCAA Partial Withdrawal Request Letter-SWCAA.pdf included in the docket for this action.
Once this action becomes effective, the Washington SIP will no longer include the following regulation for SWCAA's jurisdiction:
SWCAA Rule 400-070(2)(a), Emission Standards for Certain Source Categories, (State effective September 21, 1995);
This action also approves and incorporates by reference at 40 CFR 52.2470(c)- Table 8-Additional Regulations Approved for the Southwest Clean Air Agency (SWCAA) Jurisdiction, the following revised regulations:
• SWCAA Rule 400-040, General Standards for Maximum Emissions, establishing maximum emissions allowed in certain instances, (State effective September 10, 2021);
• SWCAA Rule 400-070, General Requirements for Certain Source Categories, establishing general standards for certain sources, (State effective September 10, 2021);
• SWCAA Rule 400-081, Startup and Shutdown, establishing certain modeling and control technology determinations for periods of startup and shutdown (State effective September 10, 2021);
• SWCAA Rule 400-107, Excess Emissions, establishing reporting and excusing of certain excess emissions, (State effective September 10, 2021).
These SIP revisions apply specifically to the jurisdiction of the Southwest Clean Air Agency in Washington State.
III. Incorporation by Reference
[top] In this rule, the EPA is finalizing regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is finalizing the incorporation by reference as described in section II of this preamble. The EPA has made, and will continue to make,

IV. Statutory and Executive Orders Reviews
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, the 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 Order 12866 (58 FR 51735, October 4, 1993);
• Is not a "significant regulatory action" subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
• 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 subject to Executive Order 13045 (62 FR 19885, April 23, 1997) because it approves a State program;
• Is not a significant regulatory action subject to Executive 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 CAA.
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).
The SIP is not approved to apply on any Indian reservation land in Washington except as specifically noted below and is also not approved to apply 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 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. Washington's SIP is approved to apply on non-trust land within the exterior boundaries of the Puyallup Indian Reservation, also known as the 1873 Survey Area. Under the Puyallup Tribe of Indians Settlement Act of 1989, 25 U.S.C. 1773, Congress explicitly provided State and local agencies in Washington authority over activities on non-trust lands within the 1873 Survey Area.
