The U.S. Environmental Protection Agency (EPA) waived a limitation on selling fuel that is more than 10 percent ethanol for model year 2007 and newer cars and light trucks. The waiver applies to fuel that contains up to 15 percent ethanol — known as E15 — and only to model year 2007 and newer cars and light trucks. This represents the first of a number of actions that are needed from federal, state and industry toward commercialization of E15 gasoline blends. EPA Administrator Lisa Jackson made the decision after a review of the Department of Energy's (DOE's) extensive testing and other available data on E15's impact on engine durability and emissions.

However, the reaction among agriculture industry groups and associations was mixed. Organizations in favor of the move included the American Farm Bureau Federation, National Corn Growers Association, Missouri Corn Growers Association, 25x'25 and USDA. Organizations that were not in favor included the Renewable Fuels Association, National Pork Producers Council and the National Cattleman's Beef Association.

The majority of concerns stemmed around potential confusion in the marketplace among consumers and the livestock industry's fears of higher feed prices due to more corn needed to produce more E15.
