Biofuels Procurement Preference
State and county agency contracts awarded for the purchase of diesel fuel must give preference to bids for biofuels or blends of biofuel and petroleum fuel. When purchasing fuel for use in diesel engines, the price preference is $0.05 per gallon of B100. For blends containing both biodiesel and petroleum-based diesel, the preference is applied only to the biodiesel portion of the blend. For the purpose of this requirement, biodiesel is a vegetable oil-based fuel that meets ASTM specification D6751 and biofuel is a fuel from non-petroleum plant- or animal-based sources that can be used for the generation of heat or power.
