Clean Fuel Contracts for Heavy-Duty Equipment

As part of the proposal process, any state agency that contracts for the use of on- or off-road heavy-duty diesel equipment in Maricopa, Pima, and Pinal Counties must provide incentives to bidders that use equipment retrofitted with diesel retrofit kits, newer clean diesel technologies and fuels, or biodiesel or other cleaner petroleum diesel alternatives.
