Exxon attacks EPA ethanol decision

EPA on Wednesday said a higher blend of ethanol in gasoline is safe to use in cars, light trucks and sport utility vehicles for model year 2007 and later, offering a partial victory for advocates of the corn-based additive.

EPA’s air quality chief, Gina McCarthy, said the decision to allow use of E-15 — which consists of 15 percent ethanol and 85 percent gasoline — for newer vehicles came after “extensive testing” at the Department of Energy. Currently, there is a 10 percent limit on ethanol content in a gallon of gasoline.
