The U.S. Environmental Protection Agency (EPA) waived a limitation on selling gasoline that contains more than 10 percent ethanol for model year (MY) 2001 through 2006 passenger vehicles, including cars, SUVs, and light pickup trucks. The waiver applies to fuel that contains up to 15 percent ethanol – known as E15.
EPA Administrator Lisa P. Jackson made the decision after a review of the Department of Energy’s thorough testing and other available data on E15’s effect on emissions from MY 2001 through 2006 cars and light trucks.
“Recently completed testing and data analysis show that E15 does not harm emissions control equipment in newer cars and light trucks," said EPA Administrator Lisa P. Jackson. "Wherever sound science and the law support steps to allow more home-grown fuels in America’s vehicles, this administration takes those steps."
On October 13, 2010, EPA approved a waiver allowing the use of E15 for MY 2007 and newer cars and light trucks. At that time, EPA denied a request to allow the use of E15 for MY 2000 and older vehicles and postponed its decision on the use of E15 in MY 2001 to 2006 cars and light trucks until DOE completed additional testing for those model years.
The Agency also announced that no waiver is being granted this year for E15 use in any motorcycles, heavy-duty vehicles, or non-road engines because current testing data does not support such a waiver. These waivers represent one of a number of actions that are needed from federal, state and industry to commercialize E15 gasoline blends. Also, EPA is developing requirements to ensure that E15 is properly labeled at the gas pump.
The label will be designed to prevent refueling into vehicles, engines, and equipment not currently approved for the higher ethanol blend. Ethanol is an alcohol that can be mixed with gasoline to result in a cleaner-burning fuel. E15 is a blend of 15 percent ethanol and 85 percent gasoline. The primary source of ethanol is corn, but other grains or biomass sources may be used such as corn cobs, cornstalks, and switchgrass.
The Energy Independence and Security Act of 2007 mandated an increase in the overall volume of renewable fuels into the marketplace, reaching a 36 billion gallon total in 2022. Ethanol is considered a renewable fuel because it is produced from plant products or wastes and not from fossil fuels.
Ethanol is blended with gasoline for use in most areas across the country. EPA granted the waiver after considering the E15 petition submitted by Growth Energy and 54 ethanol manufacturers in March 2009. In April 2009, EPA sought public comment on the petition and received about 78,000 comments. The petition was submitted under a Clean Air Act provision that allows EPA to waive the act’s prohibition against the sale of a significantly altered fuel if the petitioner shows that the new fuel will not cause or contribute to the failure of engine and other emission-related parts that ensure compliance with emission standards.
