A 2002 analysis showed that the testing and repair of collectible vehicles in the Phoenix area, and of collectible vehicles and motorcycles in the Tucson area, does not provide a significant air quality benefit. Subsequently, in 2005 the Arizona Legislature passed House Bill 2357 to authorize the exemption of these vehicles. The exemptions required the approval of the U.S. Environmental Protection Agency (EPA) and a request for approval of the exemptions was submitted to EPA on Dec. 23, 2005.

On Dec. 12, 2006, EPA signed a proposed approval of the exemptions . The proposed approval was published in the Federal Register on Dec. 28, 2006. Final approval of the exemptions was published on March 30, 2007 . EPA's approval becomes effective on April 30, 2007.

ADEQ and the Arizona Motor Vehicle Division have begun to implement this exemption. Owners of collectible vehicles must contact their insurance carriers to arrange for the required insurance. The carrier will notify MVD electronically, allowing the vehicle to be registered as a collectible vehicle. More information is available here .

Background

In 2002 the Arizona Legislature required ADEQ to study the effect of exempting motorcycles, collectible vehicles, and vehicles 25 model years old and older from the current vehicle emission testing requirements. ADEQ analyzed these vehicle categories to determine whether including them in the testing program provided a significant air quality benefit. The analysis showed that the testing and repair of collectible vehicles in the Phoenix area, and of collectible vehicles and motorcycles in the Tucson area, does not provide a significant air quality benefit. The exemption of these vehicle categories, therefore, would not interfere with continued maintenance of the carbon monoxide air quality standards and progress toward attainment of the ozone air quality standards.

• Report on Potential Exemptions from Vehicle Emissions Testing for Motorcycles, Collectible Vehicles and Vehicles 25 Model Years Old and Older

In 2005 the Arizona Legislature passed House Bill 2357, which amended the Arizona Revised Statutes (ARS) at § 49-542 to authorize the exemption of certain collectible vehicles and motorcycles from being subject to the emissions testing requirements. The legislation exempts collectible vehicles in the Phoenix testing area and collectible vehicles and motorcycles in the Tucson testing area, pending approval by EPA.

On Dec. 23, 2005, a request to incorporate these changes into Arizona's air quality State Implementation Plan (SIP) was submitted to EPA for review and approval. Copies of House Bill 2357 and the request to EPA for approval of the revision to the Arizona SIP using the links provided below:

• Final State Implementation Plan (SIP) Revision for Collectible Car and Motorcycle Exemptions

In 2006 EPA requested additional analysis to demonstrate that the emissions testing program will continue to meet the vehicle emissions program performance standard and the addition of a contingency provision in case of a violation of the carbon monoxide standards. The additional analysis and contingency provision, contained in a supplement to the 2005 SIP revision, was submitted to EPA for approval in October 2006 following public review and comment.
