Vehicle Emissions Control Rulemaking
On Feb. 23, 2018, ADEQ received an exception from the Governor’s rulemaking moratorium to rewrite Arizona Administrative Code Chapter 18, Title 2, Article 10. This rulemaking will:
- Bring the Vehicle Emissions Inspection Program (VEIP) in line with federal regulations
- Implement HB 2357 (2005) and HB 2226 (2014) into rule
- Allow the VEIP to leverage new technology
- Codify VEIP practices that have been simplified as a result of ADEQ’s adoption of the Lean Management System
- Reduce excessive audits
New rules will be effective June 1, 2019
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.
As part of the process to update VEI regulations, ADEQ must also update the SIP. This rulemaking will require ADEQ to submit an air quality analysis and formal SIP revision to the EPA before certain provisions can be implemented. These provisions are clearly notated in the updated rule package. This page will serve as a reference for interested parties on the status of the SIP revision approval.
