The U.S. D.C. Circuit Court of Appeals Tuesday denied petitions to rehear the case by the Grocery Manufacturers Association, big oil and others against the Environmental Protection Agency for permitting commercial use of E-15. Growth Energy CEO Tom Buis says this decision is a big win for renewable energy.

Buis says Growth Energy intervened in the case for EPA saying the groups didn’t have standing in the case - and earlier this year - the D.C. Circuit Court of Appeals agreed. Buis says the groups can continue to challenge this decision - but the climb would get steeper. Now - he says their only recourse would be to ask the Supreme Court to take up the case - but the renewable fuels industry receiving two favorable rulings with the Court of Appeals makes their challenge harder
