{"abstract":"The Environmental Protection Agency (EPA) is proposing to act in accordance with Ohio EPA's November 14, 2025, request to remove the air pollution nuisance rule (ANR) from the Ohio State Implementation Plan (SIP). The EPA is proposing to find that the Ohio SIP contains adequate control requirements and enforcement measures to maintain air quality in the State without the ANR. This proposed action will not interfere with the National Ambient Air Quality Standards (NAAQS) and meets all applicable requirements under the Clean Air Act (CAA).","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/2026/05/28/2026-10643.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"52","title":40}],"citation":"91 FR 31688","comment_url":"http://www.regulations.gov/commenton/EPA-R05-OAR-2025-1611-0001","comments_close_on":"2026-06-29","correction_of":null,"corrections":[],"dates":"Comments must be received on or before June 29, 2026.","disposition_notes":null,"docket_ids":["EPA-R05-OAR-2025-1611","FRL-13365-01-R5"],"dockets":[{"supporting_documents":[{"title":"OH ANR TSD","document_id":"EPA-R05-OAR-2025-1611-0014"},{"title":"5_HearingTranscript_Comments","document_id":"EPA-R05-OAR-2025-1611-0013"},{"title":"4_Comments","document_id":"EPA-R05-OAR-2025-1611-0012"},{"title":"3_Comments","document_id":"EPA-R05-OAR-2025-1611-0011"},{"title":"2_Comments","document_id":"EPA-R05-OAR-2025-1611-0010"},{"title":"1_Comments","document_id":"EPA-R05-OAR-2025-1611-0009"},{"title":"Attachment D3 Response to Comments","document_id":"EPA-R05-OAR-2025-1611-0008"},{"title":"Attachment D2 Public Notice Removal Ohio Air Nuisance Rule 2025 -
