Title: Federal/State Relations Under the Clean Air Act: The Supreme Court Takes Two Cases
Authors: Robert Meltz, American Law Division 
Abstract: Recently, the Supreme Court agreed to hear two cases involving federalism issues under the Clean Air Act (CAA). In Alaska Department of Environmental Conservation v. EPA, the Court will wrestle with whether EPA can enforce a Prevention of Significant Deterioration (PSD) provision in the CAA contrary to a prior state determination under its EPA-approved PSD program. In Engine Manufacturers Association v. South Coast Air Quality Management District, the issue is the preemptive scope of the CAA program regulating mobile sources of air pollution.
