Six biofuel industry organizations have jointly petitioned the U.S. Court of Appeals for the District of Columbia Circuit to intervene in a lawsuit filed by the American Fuel & Petrochemical Manufacturers (AFPM) and the Western States Petroleum Association (WSPA) against the U.S. Environmental Protection Agency. The biofuel organizations include the Advanced Biofuels Association, Advanced Ethanol Council, American Coalition for Ethanol, Biotechnology Industry Organization, Growth Energy and the Renewable Fuels Association.

The organizations are asking to join the AFPM et al v. EPA suit to support the EPA’s denial of a waiver of the 2011 Cellulosic Renewable Volume Obligation under the Renewable Fuel Standard (RFS). The lawsuit was filed in June 2012, the same month that the first Renewable Identification Numbers reportedly were assigned to cellulosic biofuel produced in the United States.
