## Abstract

EPA is approving two State Implementation Plan (SIP) revisions submitted by the Arizona Department of Environmental Quality (ADEQ). These revisions consist of several changes that have been made to Arizona's Basic and Enhanced Vehicle Emissions Inspection and Maintenance Programs after the programs were approved by EPA in 1995. Arizona's Basic Vehicle Emissions Inspection (VEI) Program is implemented in the Tucson Air Planning Area carbon monoxide (CO) nonattainment area (Area B). The Enhanced VEI Program is implemented in the Maricopa County ozone and CO nonattainment area (the Phoenix area or Area A).
