The Natural Resources Defense Council filed suit September 19 in the U.S. Court of Appeals for the District of Columbia Circuit against the Environmental Protection Agency. NRDC is challenging the EPA’s decision to defer for three years the requirement that facilities burning biomass fuels obtain greenhouse gas emissions permits. The Center for Biological Diversity, Georgia ForestWatch, Wild Virginia, the Conservation Law Foundation, and the Natural Resources Council of Maine filed a similar suit on August 15.
