Pinnacle Ethanol, LLC v. EPA

A group of ethanol producers filed a lawsuit challenging EPA criteria for determining which biofuels met the U.S. renewable fuels standard. The final rule exempted ethanol produced from corn at facilities in or at which construction commenced before December 17, 2007 from the requirement that a renewable fuel must reduce life-cycle GHG emissions by at least 20 percent compared with gasoline. In the final rule, EPA extended the exemption to ethanol produced at facilities that use natural gas or biofuels as an energy source at which construction began before December 31, 2009.
