With public comments on its proposal to slash the Renewable Fuel Standard currently under review, the Environmental Protection Agency has dealt yet another blow to ethanol. The agency announced yesterday that it will switch its test fuel from the proposed E15 to E10 as the certification fuel for new emissions standards to be in place by 2017.
(E15 is gasoline blended with 15 percent ethanol. E10 is blended with 10 percent ethanol.)
EPA says it’s doing this because E15 isn’t widely available on a national scale.
