{"abstract":"The Environmental Protection Agency (EPA) is granting the California Air Resources Board's (\"CARB's\") request for a waiver of Clean Air Act preemption for its greenhouse gas (\"GHG\") emission regulation for the new 2014 and subsequent model year on-road medium- and heavy-duty engines and vehicles (\"California Phase 1 GHG Regulation\") adopted in 2011. This regulation establishes requirements applicable to new motor vehicles with a gross vehicle weight rating exceeding 8,500 pounds and engines that power such motor vehicles, except for medium-duty passenger vehicles that are subject to California's Low Emission Vehicle Program. This regulation generally aligns California's GHG emission standards and test procedures with the federal GHG emission standards and test procedures that EPA adopted in 2011. A deemed-to-comply provision is included in CARB's regulation whereby manufacturers may demonstrate compliance with California's Phase 1 GHG Regulation by complying with EPA's Phase 1 regulation. This decision is issued under the authority of the Clean Air Act (\"CAA\" or \"the Act\").","action":"Notice of decision.","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/2016/12/29/2016-31646.html","cfr_references":[],"citation":"81 FR 95982","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"Petitions for review must be filed by February 27, 2017.","disposition_notes":null,"docket_ids":["EPA-HQ-OAR-2016-0179","FRL-9957-70-OAR"],"dockets":[],"document_number":"2016-31646","effective_on":null,"end_page":95987,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2016/12/29/2016-31646.xml","html_url":"https://www.federalregister.gov/documents/2016/12/29/2016-31646/california-state-motor-vehicle-pollution-control-standards-greenhouse-gas-emissions-from-2014-and","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/2016-31646?publication_date=2016-12-29","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2016-12-29/2016-31646/mods.xml","not_received_for_publication":null,"page_length":6,"page_views":{"count":524,"last_updated":"2026-10-25 14:15:05 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2016-12-29/pdf/2016-31646.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2016-31646.pdf?1482932833","publication_date":"2016-12-29","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2016/12/29/2016-31646.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"supporting_documents":[{"title":"Phase 1 GHG Waiver Support Document","document_id":"EPA-HQ-OAR-2016-0179-0026"},{"title":"Phase 1 GHG Cover Letter","document_id":"EPA-HQ-OAR-2016-0179-0025"},{"title":"Attachment 23: OAL approval letter and attached memo","document_id":"EPA-HQ-OAR-2016-0179-0024"},{"title":"Attachment 22: Form 400","document_id":"EPA-HQ-OAR-2016-0179-0023"},{"title":"Attachment 21: December 12, 2013 Transcript","document_id":"EPA-HQ-OAR-2016-0179-0022"},{"title":"Attachment 20: FSOR","document_id":"EPA-HQ-OAR-2016-0179-0021"},{"title":"Attachment 19: EO R-14-010","document_id":"EPA-HQ-OAR-2016-0179-0020"},{"title":"Attachment 18:2nd 15-Day Notice Attachment A","document_id":"EPA-HQ-OAR-2016-0179-0019"},{"title":"Attachment17: 2nd 15-Day Notice","document_id":"EPA-HQ-OAR-2016-0179-0018"},{"title":"Attachment 16: 15-Day Notice Attachment A-4","document_id":"EPA-HQ-OAR-2016-0179-0017"}],"comments_url":"https://www.regulations.gov/docketBrowser?rpp=50&so=DESC&sb=postedDate&po=0&dct=PS&D=EPA-HQ-OAR-2016-0179","supporting_documents_count":25,"docket_id":"EPA-HQ-OAR-2016-0179","regulation_id_number":null,"title":"California Waiver Request for Greenhouse Gas Standards for NEW 2014 and Subsequent Model Year On-road Medium- and Heavy-Duty Vehicles and Engines","checked_regulationsdotgov_at":"2017-01-18T06:00:23Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":95982,"subtype":null,"title":"California State Motor Vehicle Pollution Control Standards; Greenhouse Gas Emissions From 2014 and Subsequent Model Year Medium- and Heavy-Duty Engines and Vehicles; Notice of Decision","toc_doc":"Greenhouse Gas Emissions from 2014 and Subsequent Model Year Medium and Heavy-Duty Engines and Vehicles; Decision","toc_subject":"California State Motor Vehicle Pollution Control Standards:","topics":[],"type":"Notice","volume":81}
