The American Petroleum Institute and nine food and farm groups have sued EPA over last month's ruling that E15 - a blend of 15% ethanol and 85% gasoline - can be used in 2007 or newer cars, light trucks, and SUVs. The suits contend the EPA decision violates the Clean Air Act. The recent EPA waiver does not mandate the use of E15 in these vehicles, but rather it gives the green light for its use in them.
For years, ethanol has made up 10% of most gasoline sold in the US and has been used as a gasoline additive to increase combustion. The ethanol industry has been putting a lot of pressure on EPA to increase the level to 15%, but these groups were upset when the ruling said 2007 model year of newer vehicles.
Nobody's happy, and much to clean up.
