This bill proposes several updates to the current statutes regarding fuel formulation in Arizona. It introduces new provisions that require the Director of the Arizona Department of Environmental Quality (ADEQ) and the Associate Director of the Weights and Measures Services Division to collaborate on submitting an emergency fuel formulation waiver to the U.S. Environmental Protection Agency (EPA) if supply issues for gasoline or crude oil are identified. The bill specifies that this waiver request must be applicable to all registered suppliers or oxygenate blenders, not selectively applied, and must be resubmitted if the conditions for the waiver continue. Additionally, it mandates compliance with ASTM D4814 standards for gasoline during the waiver period from March 31 to October 31 each year, replacing previous reformulation options.

The bill also deletes outdated language regarding specific fuel reformulation options and introduces new requirements for suppliers or blenders petitioning for waivers. These include demonstrating imminent supply shortages and specifying alternative formulations. Furthermore, the bill establishes conditions under which the new provisions will take effect, contingent upon EPA approval of modifications to gasoline fuel formulation requirements by July 1, 2030. The Director of ADEQ is tasked with notifying the Arizona Legislative Council regarding the status of these conditions.
