Center for Biological Diversity, et al. v. EPA, et al.

This appeal concerned the EPA's decision in 2012 that it needed further studies before it could set a new, joint, "secondary" national ambient air quality standard for oxides of nitrogen and oxides of sulphur, and other related compounds found in the ambient air and considered precursors of acid deposits on the land and in the waters of the continental United States. At issue was whether EPA's decision to defer adopting a new standard at this time, pending further scientific study, violated the Clean Air Act, 42 U.S.C. 7409(d)(1). The court concluded that, because the Act requires a reasoned judgment, and because EPA found it could not form one, EPA's explanation conformed to the authorizing statute. Accordingly, the court denied the petition for review. View "Center for Biological Diversity, et al. v. EPA, et al." on Justia Law
