{"abstract":"This rule changes the test procedures previously promulgated for methanol-fueled vehicles (April 11, 1989). These revisions make minor corrections to the procedures, provide additional options, and clarify the Agency's regulatory intent. The changes are expected to allow manufacturers more flexibility in complying with the applicable regulations, without sacrificing accuracy of test results. This action is a part of an ongoing cooperative interaction between Agency staff and the affected automobile and engine manufacturers to develop the most efficient test procedures possible for alternative fuels such as methanol. Among the most significant changes are revisions to the testing requirements for flexible fuel vehicles (FFVs), the allowance of electronic mass flow controllers for methanol and formaldehyde sample systems, the allowance of lower temperatures for some heated components, establishment of wider tolerances for SHED and CVS (Constant Volume Sampler) verifications, and specification of the fuel to be used with all flame ionization detectors. It should be noted that the revision related to flame ionization detectors affects all light- duty vehicles, including gasoline-fueled vehicles. In compliance with the Paperwork Reduction Act, this rule also displays the Office of Management and Budget (OMB) control numbers issued under the Paperwork Reduction Act (PRA) for the final rules titled ``Emission Standards for Clean-fuel Vehicles and Engines, Requirements for Clean-Fuel Vehicle Conversions, and California Pilot Test Program'' and the ``Standards for Emissions from Natural Gas- Fueled, and Liquified Petroleum Gas-Fueled Motor Vehicles and Motor Vehicle Engines, and Certification Procedures for Aftermarket Conversions''. Also included in this Final Rule are minor changes that were proposed in the ``Gaseous-Fueled Vehicles'' and ``Clean Fuel Fleets'' Notices of Proposed Rulemaking, but were not finalized in the respective Final Rules.","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/1995/06/30/95-14220.html","cfr_references":[{"chapter":null,"citation_url":null,"part":9,"title":40},{"chapter":null,"citation_url":null,"part":85,"title":40},{"chapter":null,"citation_url":null,"part":86,"title":40},{"chapter":null,"citation_url":null,"part":88,"title":40},{"chapter":null,"citation_url":null,"part":600,"title":40}],"citation":"60 FR 34326","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This final rule is effective July 31, 1995, except the amendments to part 9 are effective June 30, 1995.","disposition_notes":null,"docket_ids":["AMS-FRL-5203-6"],"dockets":[],"document_number":"95-14220","effective_on":"1995-07-31","end_page":34377,"executive_order_notes":null,"executive_order_number":null,"explanation":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1995/06/30/95-14220/control-of-air-pollution-from-new-and-in-use-motor-vehicles-and-new-and-in-use-motor-vehicle-engines","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/95-14220?publication_date=1995-06-30","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1995-06-30/95-14220/mods.xml","not_received_for_publication":null,"page_length":52,"page_views":{"count":549,"last_updated":"2026-05-26 12:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1995-06-30/pdf/95-14220.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1995-06-30","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1995/06/30/95-14220.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-21T05:51:11Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":34326,"subtype":null,"title":"Control of Air Pollution From New and In-Use Motor Vehicles and New and In-Use Motor Vehicle Engines; Technical Amendments to the Test Procedures for Methanol-Fueled Motor Vehicles and Motor Vehicle Engines and Petroleum-Fueled Motor Vehicles; Final Rule","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":60}
