Biodiesel Retail and Storage Requirements
All biodiesel and biodiesel blends sold in Michigan must meet state fuel quality requirements, including ASTM D6751 specification. A refiner, distributor, or retailer cannot transfer or dispense biodiesel or biodiesel blends unless the fuel is visibly free of undissolved water, sediments, and other suspended matter. Additionally, a biodiesel retailer may not sell biodiesel or biodiesel blends drawn from a storage tank that has more than two inches of water or water-alcohol at the bottom. Any retailer of biodiesel or biodiesel blends must obtain a license from the Michigan Department of Agriculture for each operating retail location.
