A coalition of biofuel and agriculture groups petitioned the U.S. Environmental Protection Agency (EPA) to change its regulations to account for lost volumes of renewable fuel resulting from the unprecedented number of retroactive small refinery exemptions from Renewable Fuel Standard (RFS) obligations recently granted by EPA. This petition comes days after several ethanol and farm groups challenged three specific small refinery exemptions granted by EPA. While the lawsuit in the Tenth Circuit challenged those exemptions as wrongly decided, this petition to EPA seeks a broader, forward-looking remedy to account for the collective lost volumes caused by the unprecedented number of retroactive small refinery exemptions. “EPA Administrator Scott Pruitt has had a fire sale on small refiner exemptions for anyone with a stamp and an envelope, making a mockery of the President’s commitment to a 15-billion-gallon RFS for conventional biofuel. This must end. We take no pleasure in having to litigate to protect the integrity of the RFS, but it appears we have no other recourse,” said RFA CEO Bob Dinneen.
