Control of Air Pollution From New Motor Vehicles and New Motor Vehicle Engines: Evaporative and Refueling Emission Regulations for Gasoline- and Methanol-Fueled Light-Duty Vehicles and Light-Duty Trucks and Heavy-Duty Vehicles; Technical Amendments

On March 24, 1993 EPA finalized a new test procedure to measure evaporative emissions from motor vehicles. The amendments contained in this document modify several of the test procedure's tolerances, equipment specifications, and procedural steps. In compliance with the Paperwork Reduction Act, this document announces that the information collection requirements contained in the Evaporative Emissions Final Rule were approved by the Office of Management and Budget on May 9, 1994. Also, this document incorporates by reference the California Regulatory Requirements Applicable to the Evaporative Emissions Program (January 4, 1995). EPA will accept test data developed using the California procedure for demonstrating compliance with the 1996 model year federal evaporative emissions requirement for purposes of certification.
