The U.S. Environmental Protection Agency (EPA) and U.S. Department of Agriculture (USDA) announced a new initiative to expand the use of biofuels like E15 across the country. The proposal follows the administration’s decision earlier this year to lift the summertime ban on E15 sales. The newest initiative seeks to pump more than 15 billion gallons of ethanol into the nation’s fuel supply beginning in 2020. To help achieve this, one of the options the administration is considering is permitting retailers to use the same fuel tanks to store both E10 and E15, something the National Marine Manufacturers Association (NMMA) believes will create more challenges and confusion for America’s 141 million boaters. A final decision is pending, and the administration’s actions make it clear it is continuing to explore ways to increase the volume of ethanol in the nation’s fuel supply.
