On June 21, the Renewable Fuels Association, Utility Air Regulatory Group, American Forest & Paper Association, and other industry groups filed a brief criticizing the Center for Biological Diversity’s lawsuit challenging the Environmental Protection Agency’s authority to defer until 2014 greenhouse gas permitting for sources burning biomass. The brief argues that the lawsuit was premature, as EPA has not yet completed its review. In July 2011, EPA issued a final rule exempting, until July 21, 2014, these new or modified facilities from significant deterioration and Title V operating permits, after the industry argued that on a life-cycle basis emissions were minimal.
