{"abstract":"Today's action revises the Motor Vehicle Inspection/ Maintenance (I/M) requirements to: extend the deadline for beginning onboard diagnostic (OBD) inspections from January 1, 2001 to January 1, 2002; allow areas showing good cause up to an additional 12 months' delay; allow for a one-time-only, one-cycle phase-in period for the OBD-I/M check; revise and simplify the failure criteria for the OBD-I/M check; address State Implementation Plan (SIP) credit modeling for the OBD-I/M check; and, allow for limited exemptions from some OBD check failure and rejection criteria for certain model year vehicles. Today's action also provides additional flexibility to state I/M programs by allowing such programs to suspend traditional I/M tests on model year (MY) 1996 and newer, OBD-equipped vehicles provided such vehicles are subject to a check of the OBD system. Lastly, this action provides EPA's guidance regarding certain discretionary elements associated with the successful implementation of the OBD check in an I/M environment.","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/2001/04/05/01-8276.html","cfr_references":[{"chapter":null,"citation_url":null,"part":51,"title":40},{"chapter":null,"citation_url":null,"part":85,"title":40}],"citation":"66 FR 18156","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule will take effect May 7, 2001.","disposition_notes":null,"docket_ids":["FRL-6962-9"],"dockets":[],"document_number":"01-8276","effective_on":"2001-05-07","end_page":18179,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2001/04/05/01-8276.xml","html_url":"https://www.federalregister.gov/documents/2001/04/05/01-8276/amendments-to-vehicle-inspection-maintenance-program-requirements-incorporating-the-onboard","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/01-8276?publication_date=2001-04-05","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2001-04-05/01-8276/mods.xml","not_received_for_publication":null,"page_length":24,"page_views":{"count":276,"last_updated":"2026-07-28 16:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2001-04-05/pdf/01-8276.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"2001-04-05","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2001/04/05/01-8276.txt","regulation_id_number_info":{"2060-AJ03":{"issue":"200010","html_url":"https://www.federalregister.gov/regulations/2060-AJ03/amendments-to-vehicle-inspection-maintenance-program-requirements-implementing-the-onboard-diagnosti","title":"Amendments to Vehicle Inspection Maintenance Program Requirements Implementing the Onboard Diagnostic Check;
