The U.S. Environmental Protection Agency (EPA) announced Wednesday it will allow up to 15 percent ethanol to be blended with gasoline in motor fuel for use in cars and light trucks built since 2007, following testing proving the safety of the new blend, dubbed E15 (15 percent ethanol, 85 percent gasoline).

EPA Administrator Lisa P. 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.

"Thorough testing has now shown that E15 does not harm emissions control equipment in newer cars and light trucks," said Jackson in a statement. "Wherever sound science and the law support steps to allow more home-grown fuels in America's vehicles, this administration takes those steps."

The rule is expected to expand to vehicles made in 2001 and later following further testing, results of which are due in November. However, no waiver is being granted this year for E15 use in model year 2000 and earlier cars and light trucks -- or in any motorcycles, heavy-duty vehicles, or non-road engines -- because currently there is not testing data to support such a waiver, the EPA said.

To help minimize consumer confusion, the EPA has proposed specific E15 labels on gas pumps. Gasoline producers will also be required to specify the ethanol content of the gasoline it sells to gas stations.

Since 1979, up to 10 percent ethanol or E10 has been used for all conventional cars and light trucks, and non-road vehicles in the United States.
