Biodiesel Requirement for School Buses

Every school bus capable of operating on diesel fuel must be capable of operating using blends of at least 20% biodiesel (B20). At least 2% of the total volume of fuel purchased annually by local school districts statewide for use in diesel school buses must be a minimum of B20, to the extent that biodiesel blends are available and compatible with the technology of the vehicles and the equipment used.
