{"abstract":"The 1990 Clean Air Act Amendments require the establishment of two clean-fuel vehicle programs: a Clean Fuel Fleet Program and a California Pilot Test Program. Under the Clean Fuel Fleet Program, a percentage of new vehicles acquired by certain fleet owners located in covered areas will be required to meet clean-fuel fleet vehicle emission standards. Fleet owners can comply with this requirement by purchasing new clean-fuel fleet vehicles, by converting conventional vehicles to clean-fuel fleet vehicles, or by acquiring ``credits'' pursuant to a credits program. Affected states are required to revise their State Implementation Plans to implement the fleet program, including provisions to implement a credit program and exempt clean- fuel fleet vehicles from certain transportation control measures. Regulations have already been promulgated for the credit program and transportation control measures exemptions. Also, definitions of terms used with the Clean Fuel Fleet program have recently been finalized. The other Clean Air Act clean-fuel vehicle program is the California Pilot Test program. This program requires manufacturers to sell light- duty clean-fuel vehicles in the state of California. EPA has established a credit program for the California Pilot Test Program in a separate rulemaking. This action promulgates the statutory requirements that have not been implemented to date. These include the emission standards for light-duty and heavy-duty clean-fuel vehicles, regulations for the conversion of conventional vehicles to clean-fuel fleet vehicles, manufacturer California clean-fuel vehicles sales requirements under the California Pilot Test Program, and a state opt-in program for the California Pilot Test Program. The part of the conversion provisions addressing the sales volume limit beyond which special small-volume manufacturer provisions will not apply, will not become effective sooner than 60 days after publication and then only if no adverse comment is received within 30 days of publication. If adverse comment is received within 30 days of publication, EPA will withdraw this part of the rule pending a full notice and comment process on this topic.","action":"Final rule.","agencies":[],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/1994/09/30/94-22132.html","cfr_references":[{"chapter":null,"citation_url":null,"part":9,"title":40},{"chapter":null,"citation_url":null,"part":86,"title":40},{"chapter":null,"citation_url":null,"part":88,"title":40}],"citation":null,"comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This regulation is effective October 31, 1994, except that 40 CFR 88.306-94(b)(3) will become effective on November 29, 1994, unless notice is received on or before October 31, 1994, that adverse or critical comments will be submitted.
