{"abstract":"This notice presents EPA's finding required by section 112(n)(1)(A) of the Clean Air Act (CAA) as to whether regulation of emissions of hazardous air pollutants (HAP) from fossil fuel-fired electric utility steam generating units (as defined in section 112(a)(8) of the CAA) is appropriate and necessary. This finding is based on the results of EPA's February 1998 \"Study of Hazardous Air Pollutant Emissions from Electric Utility Steam Generating Units--Final Report to Congress' (utility RTC), and on information obtained subsequent to the utility RTC concerning HAP emissions to the atmosphere from electric utility steam generating units. In the utility RTC, the EPA indicated that coal- and oil-fired electric utility steam generating units are significant emitters of HAP, including mercury which is emitted from coal-fired units, and which EPA identified as the HAP of greatest concern to public health from the industry. Based on the available information, the Administrator finds that regulation of HAP emissions from coal- and oil-fired electric utility steam generating units under section 112 of the CAA is appropriate and necessary. As a result, this notice adds coal-and oil-fired electric utility steam generating units to the list of source categories under section 112(c) of the CAA. Also in the utility RTC, the EPA indicated that the impacts due to HAP emissions from natural gas-fired electric utility steam generating units were negligible based on the results of the study. The Administrator finds that regulation of HAP emissions from natural gas-fired electric utility steam generating units is not appropriate or necessary. The EPA does not believe that the definition of electric utility steam generating unit found in section 112(a)(8) of the CAA encompasses stationary combustion turbines. Therefore, the finding concerning natural-gas fired electric utility steam generating units does not apply to stationary combustion turbines.","action":"Notice of regulatory finding.","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/2000/12/20/00-32395.html","cfr_references":[],"citation":"65 FR 79825","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":null,"disposition_notes":null,"docket_ids":["AD-FRL-6919-6"],"dockets":[],"document_number":"00-32395","effective_on":null,"end_page":79831,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2000/12/20/00-32395.xml","html_url":"https://www.federalregister.gov/documents/2000/12/20/00-32395/regulatory-finding-on-the-emissions-of-hazardous-air-pollutants-from-electric-utility-steam","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/00-32395?publication_date=2000-12-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2000-12-20/00-32395/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":642,"last_updated":"2026-08-23 18:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2000-12-20/pdf/00-32395.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2000-12-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2000/12/20/00-32395.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":79825,"subtype":null,"title":"Regulatory Finding on the Emissions of Hazardous Air Pollutants From Electric Utility Steam Generating Units","toc_doc":"Electric utility steam generating units; regulatory finding","toc_subject":"Air pollutants, hazardous; national emission standards:","topics":[],"type":"Notice","volume":65}
