[JURIST] The US Supreme Court [official website; JURIST news archive] ruled [opinion, PDF] 6-3 Monday in Coeur Alaska, Inc. v. Southeast Alaska Conservation Council and Alaska v. Southeast Alaska Conservation Council [Cornell LII backgrounder; JURIST report] that the US Army Corps of Engineers [official website] may issue a permit for discharge of fill material otherwise subject to limitations under Sections 301 or 306 of the Clean Water Act (CWA) [text, PDF]. The US Court of Appeals for the Ninth Circuit had held [opinion, PDF] in favor of environmental organizations, finding that petitioner corporation's request should have been considered by the Environmental Protection Agency (EPA) [official website], rather than the Corps. In reversing, Justice Anthony Kennedy wrote:

These cases require us to address two questions under the Clean Water Act. The first is whether the Act gives authority to the United States Army Corps of Engineers, or instead to the Environmental Protection Agency (EPA), to issue a permit for the discharge of mining waste, called slurry. The Corps of Engineers has issued a permit to petitioner Coeur Alaska, Inc., for a discharge of slurry into a lake in Southeast Alaska. The second question is whether, when the Corps issued that permit, the agency acted in accordance withlaw. We conclude that the Corps was the appropriate agency to issue the permit and that the permit is lawful.
