SB 1171 updates the Michigan Motor Fuels Quality Act by clarifying and expanding the definitions of various fuel-related terms to include modern energy sources. The bill specifically adds definitions for new concepts such as hydrogen fuel, biomass-based diesel, and cosolvents, while refining existing descriptions for items like ethanol and biodiesel. These changes directly affect fuel blenders, distributors, and dispensing facilities by ensuring regulatory language accurately reflects current fuel compositions and technologies. By amending multiple sections of the law, the legislation aims to improve consistency in how fuel quality and composition are identified and regulated across the state.
