Supply of Petroleum Products for Blending with Biofuels
Petroleum product refiners and suppliers must make all grades of gasoline and diesel fuel available to any wholesaler in a condition that allows for the fuel to be blended with ethanol or other biobased products and sold in Tennessee. In addition, gasoline products must be available with detergent additives in sufficient concentrations such that after the addition of ethanol, the final product meets or exceeds the lowest additive concentrations that the U.S. Environmental Protection Agency requires.
