{"abstract":"The Environmental Protection Agency (EPA) is proposing to amend the National Emission Standards for Hazardous Air Pollutants: Coal- and Oil-Fired Electric Steam Generating Units (Mercury and Air Toxics Standards (MATS)). In addition to this proposed rule the EPA is publishing a direct final rule that amends the reporting requirements of the MATS rule by temporarily requiring affected sources to submit all required emissions and compliance reports to the EPA through the Emissions Collection and Monitoring Plan System Client Tool and temporarily suspending the requirement for affected sources to submit certain reports using the Electronic Reporting Tool and the Compliance and Emissions Data Reporting Interface. If we receive no adverse comment, we will not take further action on this proposed rule.","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/2014/11/19/2014-27127.html","cfr_references":[{"chapter":null,"citation_url":null,"part":63,"title":40}],"citation":"79 FR 68840","comment_url":null,"comments_close_on":"2014-12-19","correction_of":null,"corrections":[],"dates":"Written comments must be received by December 19, 2014.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2009-0234","FRL-9919-20-OAR"],"dockets":[],"document_number":"2014-27127","effective_on":null,"end_page":68841,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2014/11/19/2014-27127.xml","html_url":"https://www.federalregister.gov/documents/2014/11/19/2014-27127/national-emission-standards-for-hazardous-air-pollutants-coal--and-oil-fired-electric-steam","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2014-27127?publication_date=2014-11-19","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2014-11-19/2014-27127/mods.xml","not_received_for_publication":null,"page_length":2,"page_views":{"count":229,"last_updated":"2026-08-24 04:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2014-11-19/pdf/2014-27127.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2014-27127.pdf?1416318493","publication_date":"2014-11-19","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2014/11/19/2014-27127.txt","regulation_id_number_info":{"2060-AS39":{"issue":"201410","html_url":"https://www.federalregister.gov/regulations/2060-AS39/mats-electronic-reporting-interim-rule-change","title":"MATS Electronic Reporting Interim Rule Change","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=201410&RIN=2060-AS39&operation=OPERATION_EXPORT_XML","priority_category":"Substantive, Nonsignificant"}},"regulation_id_numbers":["2060-AS39"],"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.
