{"abstract":"The EPA is revising regulations governing the New Source Review (NSR) programs mandated by parts C and D of title I of the Clean Air Act (CAA or Act). These revisions include changes in NSR applicability requirements for modifications to allow sources more flexibility to respond to rapidly changing markets and to plan for future investments in pollution control and prevention technologies. Today's changes reflect EPA's consideration of discussions and recommendations of the Clean Air Act Advisory Committee's (CAAAC) Subcommittee on NSR, Permits and Toxics, comments filed by the public, and meetings and discussions with interested stakeholders. The changes are intended to provide greater regulatory certainty, administrative flexibility, and permit streamlining, while ensuring the current level of environmental protection and benefit derived from the program and, in certain respects, resulting in greater environmental protection.","action":"Final 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/2002/12/31/02-31899.html","cfr_references":[{"chapter":null,"citation_url":null,"part":51,"title":40},{"chapter":null,"citation_url":null,"part":52,"title":40}],"citation":"67 FR 80186","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective on March 3, 2003.","disposition_notes":null,"docket_ids":["AD-FRL-7414-5"],"dockets":[],"document_number":"02-31899","effective_on":"2003-03-03","end_page":80289,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2002/12/31/02-31899.xml","html_url":"https://www.federalregister.gov/documents/2002/12/31/02-31899/prevention-of-significant-deterioration-psd-and-nonattainment-new-source-review-nsr-baseline","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/02-31899?publication_date=2002-12-31","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2002-12-31/02-31899/mods.xml","not_received_for_publication":null,"page_length":104,"page_views":{"count":5864,"last_updated":"2026-09-23 06:15:06 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2002-12-31/pdf/02-31899.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2002-12-31","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2002/12/31/02-31899.txt","regulation_id_number_info":{"2060-AE11":{"issue":"200210","html_url":"https://www.federalregister.gov/regulations/2060-AE11/prevention-of-significant-deterioration-psd-and-nonattainment-new-source-review-nsr-baseline-emissio","title":"Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NSR):  Baseline Emissions Determination, Actual-to-Future-Actual Methodology, Plantwide Applicability","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=200210&RIN=2060-AE11&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["2060-AE11"],"regulations_dot_gov_info":{},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":80186,"subtype":null,"title":"Prevention of Significant Deterioration (PSD) and Nonattainment New Source Review (NSR): Baseline Emissions Determination, Actual-to-Future-Actual Methodology, Plantwide Applicability Limitations, Clean Units, Pollution Control Projects","toc_doc":"Prevention of significant deterioration and nonattainment new source review; baseline emissions determination, actual-to-future-actual methodology, etc.","toc_subject":"Air quality implementation plans:","topics":["Administrative practice and procedure","Air pollution control","Carbon monoxide","Environmental protection","Hydrocarbons","Intergovernmental relations","Lead","Nitrogen oxides","Ozone","Particulate matter","Sulfur oxides"],"type":"Rule","volume":67}
