## Abstract

The provisions of subpart C of Title II of the Clean Air Act require states with certain ozone and carbon monoxide (CO) nonattainment areas to revise their State Implementation Plans (SIP) to incorporate a Clean Fuel Fleet Program. Under this program, specified percentages of new vehicles acquired by covered fleet operators in certain ozone and CO nonattainment areas must meet EPA's clean-fuel vehicle (CFV) emissions standards. Today's action delays by one model year, the requirement that a covered area's State Implementation Plan implement a Clean Fuel Fleet Program (CFFP) fleet operator purchase requirement. As a result, EPA may approve a CFFP SIP revision which provides that covered fleet operators must include a certain percentage of CFVs in their fleet vehicle purchases each year beginning with model year 1999. This action is intended to ensure successful implementation of the CFFP, and to ensure that an adequate supply of appropriate vehicles is available for fleet operators to purchase and use once the program is underway, so that compliance with the mandatory purchase requirements will be possible and economically feasible for covered fleet operators.
