Updated Vehicle Emissions Control Rule (Arizona Administrative Code Title 18, Chapter 2, Article 10)

ADEQ received an exemption from the Governor's rulemaking moratorium to rewrite Arizona Administrative Code Title 18, Chapter 2, Article 10. The updated rule:

  • Brings the Vehicle Emissions Inspection Program (VEIP) in line with federal regulations
  • Implements HB 2357 (2005) and HB 2226 (2014) into the rule
  • Allows the VEIP to leverage new technology
  • Codifies VEIP practices that were simplified as a result of process improvements
  • Reduces excessive audits

Arizona’s VEIP is run pursuant to Arizona Revised Statutes Title 49, Chapter 3, Article 5. The VEIP has been approved by the Environmental Protection Agency (EPA) as a part of Arizona’s State Implementation Plan (SIP). The VEIP remains an integral part of the Arizona SIP, and a key cog in the state’s ability to meet National Ambient Air Quality Standards (NAAQS). A VEI program is an “applicable requirement” for the Phoenix carbon monoxide (CO) and ozone planning areas under the EPA’s anti-backsliding provisions.
