{"abstract":"The Environmental Protection Agency (EPA) is proposing to approve a State Implementation Plan (SIP) revision submitted by the State of North Carolina, through the North Carolina Division of Air Quality (NCDAQ), on October 1, 2024. The revision seeks to remove North Carolina's vehicle inspection and maintenance (I/M) program from North Carolina's SIP which covers 19 counties. EPA is proposing to approve this change as it will not interfere with any applicable requirement concerning attainment and reasonable further progress or any other applicable requirement of the Clean Air Act (CAA or Act).","action":"Proposed 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/2026/05/08/2026-09146.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"52","title":40}],"citation":"91 FR 25257","comment_url":"http://www.regulations.gov/commenton/EPA-R04-OAR-2025-0305-0009","comments_close_on":"2026-06-08","correction_of":null,"corrections":[],"dates":"Comments must be received on or before June 8, 2026.","disposition_notes":null,"docket_ids":["EPA-R04-OAR-2025-0305","FRL-13350-01-R4"],"dockets":[{"supporting_documents":[{"title":"2025_NC_Network Plan Response","document_id":"EPA-R04-OAR-2025-0305-0008"},{"title":"North Carolina EE Canadian Wildfire PM TSD_090225","document_id":"EPA-R04-OAR-2025-0305-0007"},{"title":"2024 NC EER Concurrence Letter_EPA_Signed_090225","document_id":"EPA-R04-OAR-2025-0305-0006"},{"title":"NCDAQ_Final_PM2.5_EEDemo_Transmittal_Letter_020625","document_id":"EPA-R04-OAR-2025-0305-0005"},{"title":"Final NCDAQ Exceptional Events Demonstration_20250206","document_id":"EPA-R04-OAR-2025-0305-0004"},{"title":"NCDAQ_Final_SIP_Rev_19Cnty_IM_MarkUp_100124","document_id":"EPA-R04-OAR-2025-0305-0003"},{"title":"NCDAQ_Final_NIDemo_19Cnty_IM_Transmittal_Letter_100124","document_id":"EPA-R04-OAR-2025-0305-0002"},{"title":"NCDAQ_Final_NIDemo_19Cnty_IM_Narrative_Appdx_A-E_100124","document_id":"EPA-R04-OAR-2025-0305-0001"}],"agency_name":"EPA","documents":[{"comment_count":13,"comment_start_date":"2026-05-08","updated_at":"2026-05-09T01:56:42.090-04:00","comment_url":"https://www.regulations.gov/commenton/EPA-R04-OAR-2025-0305-0009","allow_late_comments":false,"id":"EPA-R04-OAR-2025-0305-0009","comment_end_date":"2026-06-09","regulations_dot_gov_open_for_comment":true}],"supporting_documents_count":8,"id":"EPA-R04-OAR-2025-0305","title":"Air Plan Approval;
