E15
The U.S. Environmental Protection Agency (EPA) defines E15 as gasoline blended with 10.5%-15% ethanol. In 2011, EPA approved E15 for use in light-duty conventional vehicles of model year 2001 and newer, through a Clean Air Act waiver request, based on significant testing and research funded by the Department of Energy’s Vehicle Technologies Office. Stations are not required to sell E15. E10 remains the limit for passenger vehicles older than the 2001 model year and for other non-road and small engines and vehicles that use gasoline, such as lawn mowers, motorcycles, and boats. E15 is not widely available. It is currently sold at more than 100 stations largely concentrated in the Midwest. As a result of the United States Department of Agriculture’s Biofuels Infrastructure Partnership, $210 million has been set aside for the installation of new ethanol infrastructure in 2016, which will increase the availability of E15.
