A coalition of biofuels and agriculture groups are demanding the Environmental Protection Agency account for lost volumes under the Renewable Fuel Standard. The coalition says the volumes, or gallons in question, were lost to hardship waivers granted to refiners by the EPA, which is estimated at more than one billion gallons of the 15-billion-gallon target. National Corn Growers Association President Kevin Skunes says the lost volumes “are having a negative effect on the nation’s corn growers” at a time when net farm income is projected to hit its lowest point in 12 years. The petition filed by the coalition included the Renewable Fuels Association, the American Coalition for Ethanol, Growth Energy, the National Biodiesel Board, the National Corn Growers Association, the Biotechnology Industry Organization, and National Farmers Union. The group also filed suit in the Court of Appeals for the District of Columbia Circuit on the same issue. However, the petitioners at the same time requested that the court stay proceedings for a period of time.
