Fuel Quality Waivers

The Weights and Measures Service Division (WMSD), working with the Arizona Department of Environmental Quality (ADEQ) and the Environmental Protection Agency (EPA), responds quickly to evaluate the potential need for a fuel waiver under the Clean Air Act.  A fuel waiver is a temporary waiver of certain controls or prohibitions on the use of a fuel or a fuel additive by the EPA.  In the event of a fuel waiver issued by EPA, WMSD issues enforcement discretion related to state fuel requirements.
