Bill > HB2955

This bill modifies Arizona's laws regarding gasoline formulations to improve air quality, particularly in counties with a population of one million two hundred thousand or more and within "Area A" (a designated air quality region). The key changes involve seasonal adjustments to gasoline standards: from March 31 to October 31, gasoline must meet ASTM D4814 standards and specific vapor pressure requirements, while from November 1 to March 31, it must meet California phase 2 reformulated gasoline standards, also with specific vapor pressure requirements. The bill also allows registered suppliers or oxygenate blenders to petition for temporary waivers from these standards if they face imminent danger of supply shortages of ethanol or gasoline, requiring them to demonstrate the issue and propose an alternative formulation or blend. Furthermore, it updates the rules for Area C, requiring gasoline sold there from March 31 to October 31 to meet ASTM D4814 standards and specific vapor pressure requirements, and also allows for petitions for temporary waivers due to imminent supply shortages. Importantly, these changes are conditional and will only become effective if the U.S. Environmental Protection Agency (EPA) approves them as part of Arizona's state implementation plan for air quality by July 1, 2030.
