{"abstract":"The U.S. Environmental Protection Agency (EPA) is correcting a final rule that published in the Federal Register (FR) on February 24, 2026, and will become effective on April 27, 2026. The EPA finalized the repeal of specific amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for Coal- and Oil-Fired Electric Utility Steam Generating Units (EGUs), commonly referred to as the Mercury and Air Toxics Standards (MATS), that were promulgated on May 7, 2024 (\"MATS NESHAP\"). This action corrects inadvertent typographical errors and minor omitted text in the Federal Register. The corrections described in this action do not affect the substantive requirements of the final rule that repeal specific amendments to the MATS NESHAP, promulgated on May 7, 2024.","action":"Final rule; correction.","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/2026/04/16/2026-07396.html","cfr_references":[{"chapter":null,"citation_url":null,"part":"63","title":40}],"citation":"91 FR 20368","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The correction is effective April 27, 2026.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2018-0794","FRL-6716.4-03-OAR"],"dockets":[],"document_number":"2026-07396","effective_on":"2026-04-27","end_page":20369,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2026/04/16/2026-07396.xml","html_url":"https://www.federalregister.gov/documents/2026/04/16/2026-07396/national-emission-standards-for-hazardous-air-pollutants-coal--and-oil-fired-electric-utility-steam","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2026-07396?publication_date=2026-04-16","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2026-04-16/2026-07396/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":81,"last_updated":"2026-04-16 14:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2026-04-16/pdf/2026-07396.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2026-07396.pdf?1776257117","publication_date":"2026-04-16","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2026/04/16/2026-07396.txt","regulation_id_number_info":{"2060-AW68":{"issue":"202504","html_url":"https://www.federalregister.gov/regulations/2060-AW68/repeal-of-amendments-to-national-emission-standards-for-hazardous-air-pollutants-coal-and-oil-fired-","title":"Repeal of Amendments to National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Utility Steam Generating Units","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202504&RIN=2060-AW68&operation=OPERATION_EXPORT_XML","priority_category":"Economically Significant"}},"regulation_id_numbers":["2060-AW68"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Measuring the Impacts of Teachers II: Teacher Value-Added and Student Outcomes in Adulthood.","document_id":"EPA-HQ-OAR-2018-0794-6941"},{"title":"Emergent Risks and Key Vulnerabilities In Climate Change 2014: Impacts, Adaptation, and Vulnerability.
