Ethanol and biodiesel fuel retailers must label retail dispensing units with the price, name, and main components of the fuel or fuel blend being sold. The labeling must follow established labeling specifications for petroleum-based fuels. Suppliers of ethanol and biodiesel must provide fuel retailers with an invoice stating the fuel blend. Alcohol fuel blends containing at least 1% of alcohol by volume must also be clearly labeled at the dispenser and on any price advertisements. Biodiesel and biodiesel blends must be identified by the capital letter "B" followed by the numerical value representing the percentage of biodiesel fuel. Additional specifications may apply.
