Arizona lawmakers are asking the the U.S. Environmental Protection Agency to exempt the Phoenix metro area from emissions testing requirements for motorcycles.
The Arizona Department of Environmental Quality on Wednesday petitioned to exempt motorcycles from such testing, according to the Phoenix Business Journal.
The ADEQ says motorcycles make up only 3.5 percent of vehicles tested in the Valley, emissions failure rates among motorcycles are down and required repairs do little to improve air quality.
The state says Phoenix is the only major metro area in the U.S. where motorcycles are required to be tested for emissions.
EPA would need to approve an exemption before next July for it to take effect.
