Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Clean Vehicles Program

EPA is approving a State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania. This SIP revision contains Pennsylvania's Clean Vehicle Program, which adopts California's second generation low emission vehicle program for light- duty vehicles (LEV II). The Clean Air Act (CAA) contains specific authority allowing any state to adopt new motor vehicle emissions standards that are identical to California's standards in lieu of applicable Federal standards. Pennsylvania has adopted a Clean Vehicle Program that incorporates by reference provisions of California's LEV II rules and specifies a transition mechanism for compliance with these clean vehicle standards in Pennsylvania. EPA is approving this SIP revision, in accordance with the requirements of the CAA, which will help Pennsylvania to achieve and maintain attainment of the National Ambient Air Quality Standard (NAAQS) for ozone.
