## Abstract

EPA is approving a State Implementation Plan (SIP) revision from the State of California demonstrating that the California Low Emission Vehicle (LEV) program qualifies as a substitute for the Clean Air Act (CAA) Clean Fuel Fleet (CFF) vehicle program. The CAA requires states, in order to opt-out of the CFF vehicle program, to submit a substitute program for all or a portion of the program which consists of measures not otherwise required by the Act and that achieves at least equal long-term emission reductions of ozone-producing and air toxic emissions. EPA is taking these actions under provisions of the CAA regarding EPA action on SIP submittals, SIPs for national ambient air quality standards (NAAQS), and plan requirements for nonattainment areas.
