Biofuels Definitions and Specifications

Biodiesel is defined as a fuel that is produced from nonpetroleum renewable resources and meets ASTM Standard D6751 and the U.S. Environmental Protection Agency registration requirements for fuels and fuel additives established in Section 211 of the Clean Air Act. E85 is defined as a blend of fuel ethanol and gasoline that meets ASTM Standard D5798. The Arizona Department of Weights and Measures must adopt rules to establish and enforce federal standards and ASTM test methods for biofuels and biofuel blends, and blenders of biodiesel must follow the established reporting requirements.

At least 75% of the total municipal fleet must operate on alternative fuels. Alternatively, municipal fleets may meet AFV acquisition requirements through biodiesel or other alternative fuel use or apply for waivers. Local governments in counties with populations of more than 500,000 people with bus fleets must purchase or convert buses to operate on alternative fuels.
