Municipal Alternative Fuel Vehicle (AFV) Acquisition Requirements

Local governments in Maricopa, Pinal, and Yavapai counties with a population of more than 1.2 million people must develop and implement vehicle fleet plans to encourage and increase the use of alternative fuels in municipal fleets. 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. For the purpose of these requirements, alternative fuels include propane, natural gas, electricity, hydrogen, qualified diesel fuel substitutes, E85, and a blend of hydrogen with propane or natural gas.
