{"abstract":"The Environmental Protection Agency (EPA) is approving Washington State Implementation Plan (SIP) revisions to the Energy Facility Site Evaluation Council (EFSEC) air quality regulations submitted by the State of Washington, through the Department of Ecology (Ecology) on June 15, 2023. The revisions were submitted in response to the EPA's June 12, 2015 \"SIP call\" in which the EPA found substantially inadequate a Washington SIP provision 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 includes removal of the substantially inadequate provision which corrects the EFSEC 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the revisions submitted that were not identified in the 2015 SSM SIP call and therefore the EPA is not approving those withdrawn portions.","action":"Final rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION AGENCY","name":"Environmental Protection Agency","id":145,"url":"https://www.federalregister.gov/agencies/environmental-protection-agency","json_url":"https://www.federalregister.gov/api/v1/agencies/145","parent_id":null,"slug":"environmental-protection-agency"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2024/12/27/2024-30536.html","cfr_references":[{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"89 FR 105456","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective January 27, 2025.","disposition_notes":null,"docket_ids":["EPA-R10-OAR-2024-0372","FRL-12293-02-R10"],"dockets":[{"supporting_documents":[{"title":"102_state submittal_EFSEC SSM SIP Revision","document_id":"EPA-R10-OAR-2024-0372-0007"},{"title":"101_state submittal_Transmittal Letter","document_id":"EPA-R10-OAR-2024-0372-0006"},{"title":"103_state submittal_Adoption Order","document_id":"EPA-R10-OAR-2024-0372-0005"},{"title":"202_state submittal supplement_EFSEC Partial Withdrawal Request Letter - EFSEC","document_id":"EPA-R10-OAR-2024-0372-0004"},{"title":"301_EFSEC SSM SIP Call FFS Completeness Letter","document_id":"EPA-R10-OAR-2024-0372-0003"},{"title":"201_state submittal supplement_EFSEC Partial Withdrawal Request Letter - Ecology","document_id":"EPA-R10-OAR-2024-0372-0002"}],"agency_name":"EPA","documents":[{"comment_count":0,"comment_start_date":"2024-12-27","updated_at":"2024-12-27T15:01:23.801-05:00","comment_url":"https://www.regulations.gov/commenton/EPA-R10-OAR-2024-0372-0009","allow_late_comments":false,"id":"EPA-R10-OAR-2024-0372-0009","comment_end_date":null,"regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":6,"id":"EPA-R10-OAR-2024-0372","title":"Air Plan Approval;
