Oklahoma v. EPA

In consolidated cases for review, petitioners challenged a rule by the United States Environmental Protection Agency under the Clean Air Act. Petitioners argued that the EPA impermissibly rejected Oklahoma’s plan to limit the emissions of sulfur dioxide at Oklahoma Gas and Electric Company power plants and replaced it with its own more stringent regulations, which petitioners contended usurped the state’s authority and would require sizable expenditures on unnecessary technology. The Tenth Circuit concluded the EPA has authority to review the state’s plan and that it lawfully exercised that authority in rejecting it and promulgating its own. Accordingly, the Court denied the petitions. View "Oklahoma v. EPA" on Justia Law
