Biodiesel Blend Use Requirement

Any diesel-powered vehicle owned or operated by the state, county or local government, school district, community college, public college or university, or mass transit agency must use a biodiesel blend that contains at least 5% biodiesel (B5) when fueling at a bulk central fueling facility. These entities are required to use B5 where available unless the vehicle engine is designed or retrofitted to operate on a higher percentage of biodiesel or on ultra-low sulfur diesel.
