{"abstract":"This document proposes to repeal \"The Safer Affordable Fuel- Efficient (SAFE) Vehicles Rule Part One: One National Program,\" published Sept. 27, 2019 (SAFE I Rule), in which NHTSA codified regulatory text and made additional pronouncements regarding the preemption of state and local laws related to fuel economy standards. Specifically, this document proposes to fully repeal the regulatory text and appendices promulgated in the SAFE I Rule. In addition, this document proposes to repeal and withdraw the interpretative statements made by the Agency in the SAFE I Rule preamble, including those regarding the preemption of particular state Greenhouse Gas (GHG) Emissions standards or Zero Emissions Vehicle (ZEV) mandates. As such, this document proposes to establish a clean slate with respect to NHTSA's regulations and interpretations concerning preemption under the Energy Policy and Conservation Act (EPCA).","action":"Notice of proposed rulemaking.","agencies":[{"raw_name":"DEPARTMENT OF TRANSPORTATION","name":"Transportation Department","id":492,"url":"https://www.federalregister.gov/agencies/transportation-department","json_url":"https://www.federalregister.gov/api/v1/agencies/492","parent_id":null,"slug":"transportation-department"},{"raw_name":"National Highway Traffic Safety Administration","name":"National Highway Traffic Safety Administration","id":345,"url":"https://www.federalregister.gov/agencies/national-highway-traffic-safety-administration","json_url":"https://www.federalregister.gov/api/v1/agencies/345","parent_id":492,"slug":"national-highway-traffic-safety-administration"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/2021/05/12/2021-08758.html","cfr_references":[{"chapter":null,"citation_url":null,"part":531,"title":49},{"chapter":null,"citation_url":null,"part":533,"title":49}],"citation":"86 FR 25980","comment_url":null,"comments_close_on":"2021-06-11","correction_of":null,"corrections":[],"dates":"Comments must be received by June 11, 2021.","disposition_notes":null,"docket_ids":["Docket No. NHTSA-2021-0030"],"dockets":[{"supporting_documents":[],"agency_name":"NHTSA","documents":[{"comment_count":445,"comment_start_date":"2021-05-12","updated_at":"2023-02-28T20:26:38.176-05:00","comment_url":"https://www.regulations.gov/commenton/NHTSA-2021-0030-0001","allow_late_comments":null,"id":"NHTSA-2021-0030-0001","comment_end_date":"2021-06-12","regulations_dot_gov_open_for_comment":false}],"supporting_documents_count":0,"id":"NHTSA-2021-0030","title":"Parts 531 and 533, NPRM, Corporate Average Fuel Economy (CAFE) Preemption"}],"document_number":"2021-08758","effective_on":null,"end_page":25992,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2021/05/12/2021-08758.xml","html_url":"https://www.federalregister.gov/documents/2021/05/12/2021-08758/corporate-average-fuel-economy-cafe-preemption","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2021-08758?publication_date=2021-05-12","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2021-05-12/2021-08758/mods.xml","not_received_for_publication":null,"page_length":13,"page_views":{"count":2320,"last_updated":"2026-04-22 16:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2021-05-12/pdf/2021-08758.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2021-08758.pdf?1620737115","publication_date":"2021-05-12","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2021/05/12/2021-08758.txt","regulation_id_number_info":{"2127-AM33":{"issue":"202110","html_url":"https://www.federalregister.gov/regulations/2127-AM33/corporate-average-fuel-economy-cafe-preemption","title":"Corporate Average Fuel Economy (CAFE) Preemption","xml_url":"http://www.reginfo.gov/public/do/eAgendaViewRule?pubId=202110&RIN=2127-AM33&operation=OPERATION_EXPORT_XML","priority_category":"Other Significant"}},"regulation_id_numbers":["2127-AM33"],"regulations_dot_gov_info":{"supporting_documents":[],"regulatory_plan":{"html_url":"https://www.federalregister.gov/regulations/2127-AM33/corporate-average-fuel-economy-cafe-preemption","title":"Corporate Average Fuel Economy (CAFE) Preemption"},"comments_count":445,"agency_id":"NHTSA","comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=NHTSA-2021-0030","supporting_documents_count":0,"docket_id":"NHTSA-2021-0030","document_id":"NHTSA-2021-0030-0001","regulation_id_number":"2127-AM33","title":"Parts 531 and 533, NPRM, Corporate Average Fuel Economy (CAFE) Preemption","checked_regulationsdotgov_at":"2023-03-01T01:26:37Z"},"regulations_dot_gov_url":null,"significant":true,"signing_date":null,"start_page":25980,"subtype":null,"title":"Corporate Average Fuel Economy (CAFE) Preemption","toc_doc":"Corporate Average Fuel Economy Preemption","toc_subject":null,"topics":["Fuel economy"],"type":"Proposed Rule","volume":86}
