U.S. carmakers and engine manufacturers appealed for the U.S. Environmental Protection Agency to reconsider its October decision, which allows the sale of gasoline with 15 percent ethanol.
In a statement, the Engine Products Group said the ruling should be sent back to the agency, and a court should review whether its “partial waiver” allowing so-called E-15 fuels, violates the federal Clean Air Act.
The petition was lodged in the federal appeals court in Washington. A spokesman for the group, Kris Kiser, said the organizations collectively represent about 400 million engine products used by tens of millions of people every day in the U.S.
On Oct. 13, 2010, the EPA granted a request from ethanol producers, including Archer Daniels Midland Co., to increase concentrations of the corn-based fuel additive in gasoline for vehicles made for 2007 and later. The previous limit was 10 percent. EPA is still studying whether to allow higher concentrations of ethanol in vehicles older than the 2007 model year.
The Renewable Fuels Association, an ethanol trade association in Washington, said the EPA could have avoided this kind of market confusion by following all the science to its logical conclusion and allowing the use of E15 for all cars and light duty pickup trucks.
It adds that “the only way” to achieve the nation's energy, economic and environmental goals as mentioned in the Renewable Fuels Standard is to raise ethanol consumption. [via autonews - sub. required]
