Utility Air Regulatory Group, et al. v. U.S. Environmental Protection Agency (U.S. 12-1146 and consolidated cases)
In January 2014, the Clinic filed an amicus brief in a U.S. Supreme Court case involving challenges to EPA’s regulation of greenhouse gas emissions from stationary sources under the Prevention of Significant Deterioration program of the Clean Air Act. In the brief, filed on behalf of Calpine Corporation, the Clinic described Calpine’s experience as a company that had gone through the PSD permitting process for greenhouse gases on six occasions. In contrast to the assertions of some of the petitioners in the case, Calpine’s experience demonstrated that GHG PSD permitting has not resulted in excessive delays or costs.
