Alternative Fuel Labeling Requirements

Retailers offering alternative fuel for sale must ensure dispensers are labeled with information to help consumers make informed decisions about fueling a vehicle, including the name of the fuel and the minimum percentage of the main component of the fuel. Labels may also list the percentage of other fuel components. This requirement applies to, but is not limited to, the following fuel types: methanol, denatured ethanol, and/or other alcohols; mixtures containing 85% or more by volume of methanol and/or other alcohols; mixtures containing more than 10% but less than 83% by volume of ethanol; natural gas; propane; hydrogen; coal derived liquid biofuel; and electricity.

Fuel dispensers distributing biodiesel blends containing more than 5% biodiesel by volume must include the percentage of biodiesel included. For ethanol blends containing no greater than 50% ethanol by volume, retailers must post the exact percentage of ethanol concentration, rounded to the nearest multiple of 10. For ethanol blends containing more than 50% but no greater than 83% ethanol by volume, retailers must (1) post the exact percentage of ethanol concentration, (2) post the percentage rounded to the nearest multiple of 10, or (3) post notice that the fuel contains 51% to 83% ethanol.

Electric vehicle supply equipment (EVSE) manufacturers must determine and disclose (via a delivery ticket or permanent label or marking) kilowatt capacity, voltage, whether the voltage is alternating current or direct current, amperage, and whether the system is conductive or inductive.
