Vehicle Emissions Inspection Programs

Vehicle Emissions Inspection Programs

On March 20, 2007, EPA approved several changes made to Arizona's Basic and Enhanced Vehicle Emissions Inspection (VEI) programs since revisions to the programs were last approved by EPA in 2003. Arizona's Basic VEI program is in effect in the Tucson carbon monoxide (CO) maintenance area. It was included as a control measure in Tucson's maintenance plan for CO. The Enhanced VEI program is in effect in the Phoenix ozone and carbon monoxide nonattainment areas, and is helping Phoenix attain and maintain the national air quality standards for CO and ozone. These changes were published in the Federal Register on March 30, 2007 and are effective on April 30, 2007.

The approved program changes include:

  • an exemption from the enhanced VEI program for collectible vehicles in the Phoenix area, and
  • an exemption from the basic VEI program for collectible vehicles and motorcycles in the Tucson area.

EPA also approved the enhanced VEI program in Phoenix as meeting EPA's enhanced inspection and maintenance program requirements.
