Arizona Fuel Use Requirement

Alternative Fuel Use and Acquisition Requirements

Local governments in defined areas of Maricopa, Pinal, and Yavapai counties with a population of more than 1.2 million people are required to develop and implement a vehicle fleet plan for the purpose of encouraging and increasing the use of alternative and clean burning fuels in vehicles owned by a city or town. At least 75% of the local government fleet must operate on alternative and clean burning fuels. The fleet plans must include the use of alternative and clean burning fuels in the bus fleet or regional public transportation authorities operated by covered locales, and all newly purchased buses must use alternative or clean burning fuel. School districts in defined areas of these counties, with an average student population of more than 3,000 students are required to ensure that 50% of the portion of the fleet with a gross vehicle weight rating of at least 17,500 pounds operate on alternative or clean burning fuels, ultra low sulfur diesel, or meet specified emissions standards. Applications for waivers are available.

At least 75% of new light-duty vehicles purchased by the state fleet must be capable of operating on alternative or clean burning fuels. For state and federal vehicles that operate primarily in counties with a population of more than 1.2 million people, at least 90% of the total state and federal fleets must operate on alternative or clean burning fuels. Pertaining to the use of an alcohol-fueled vehicle, state agencies must demonstrate that the fuel for the vehicle is available within a 10-mile radius of the primary home base of that vehicle.

Vehicle acquisition credits may be earned as follows: 1) every 450 gallons of neat biodiesel (B100) or 2,250 gallons of a diesel fuel substitute is equivalent to one vehicle acquisition; 2) every 530 gallons of E85 is equivalent to one vehicle acquisition.
