{"abstract":"The Environmental Protection Agency (EPA) is taking final action on its reconsideration of the startup and shutdown provisions in the final rules titled, \"National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-fired Electric Utility Steam Generating Units and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-Commercial-Institutional, and Small Industrial- Commercial-Institutional Steam Generating Units.\" The national emission standards for hazardous air pollutants (NESHAP) issued pursuant to Clean Air Act (CAA) section 112 are referred to as the Mercury and Air Toxics Standards (MATS), and the new source performance standards (NSPS) issued pursuant to CAA section 111 are referred to as the Utility NSPS. On November 30, 2012, the U.S. Environmental Protection Agency (EPA) granted reconsideration of, proposed, and requested comment on a limited set of issues in the February 16, 2012, final MATS and Utility NSPS, including certain issues related to the final work practice standards applicable during startup periods and shutdown periods. On June 25, 2013, the EPA reopened the public comment period for the reconsideration issues related to the startup and shutdown provisions of MATS and the startup and shutdown provisions related to the particulate matter (PM) standard in the Utility NSPS. The EPA is now taking final action on the standards applicable during startup periods and shutdown periods in MATS and on startup and shutdown provisions related to the PM standard in the Utility NSPS.","action":"Final rule; notice of final action on reconsideration.","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/2014/11/19/2014-27125.html","cfr_references":[{"chapter":null,"citation_url":null,"part":60,"title":40},{"chapter":null,"citation_url":null,"part":63,"title":40}],"citation":"79 FR 68777","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"The effective date of the rule is November 19, 2014.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2009-0234","EPA-HQ-OAR-2011-0044","FRL-9919-29-OAR"],"dockets":[],"document_number":"2014-27125","effective_on":"2014-11-19","end_page":68795,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2014/11/19/2014-27125.xml","html_url":"https://www.federalregister.gov/documents/2014/11/19/2014-27125/reconsideration-of-certain-startupshutdown-issues-national-emission-standards-for-hazardous-air","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2014-27125?publication_date=2014-11-19","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2014-11-19/2014-27125/mods.xml","not_received_for_publication":null,"page_length":19,"page_views":{"count":8734,"last_updated":"2026-09-22 08:15:09 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2014-11-19/pdf/2014-27125.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2014-27125.pdf?1416318484","publication_date":"2014-11-19","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2014/11/19/2014-27125.txt","regulation_id_number_info":{"2060-AS07":{"issue":"201410","html_url":"https://www.federalregister.gov/regulations/2060-AS07/neshap-from-coal-and-oil-fired-steam-egu-units-and-standards-of-performance-for-fossil-fuel-fired-el","title":"NESHAP From Coal-& Oil-Fired Steam EGU Units & Standards of Performance for Fossil-Fuel_Fired Electric Utility Ind-Com-Institutional & Small Ind-Com-Institutional Steam Generating Units","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201410&RIN=2060-AS07&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AS07"],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Letter from Lee Zeugin, Hunton & Williams (on behalf of Utility Air Regulatory Group(UARG)), to Lisa Jackson, USEPA","document_id":"EPA-HQ-OAR-2009-0234-9859"},{"title":"Letter from Debra Jezouit, BakerBotts, to Robert J.
