Alaska v. Southeast Alaska Conservation Council et al.

Questions presented

SCOTUS records, cert granted 27 Jun 2008

Whether the Ninth Circuit erred in invalidating the longstanding regulatory interpretation of the U.S. Army Corps of Engineers (the “Corps”) and the Environmental Protection Agency (“EPA”) that discharges of dredged or fill material are subject to the exclusive permitting authority of the Corps under Section 404 of the Clean Water Act, rather than effluent limitations and standards of performance promulgated under Sections 301 and 306 and applied by EPA pursuant to its separate permitting authority under Section 402.

Opinion summary

Etalia.ai summary of the majority opinion

The case involved a dispute over whether the U.S. Army Corps of Engineers could issue permits under Section 404 of the Clean Water Act for discharges into navigable waters, specifically concerning a mining company’s plan to dispose of waste in an Alaskan lake. The Southeast Alaska Conservation Council and other environmental groups challenged the permit, arguing that it violated EPA regulations prohibiting such disposal if it would significantly degrade water quality or affect fish populations adversely. The Supreme Court ruled in favor of Alaska and Coeur Alaska Inc., holding that the discharge was permissible because it fell within an exception allowing certain fill materials to be deposited into waterways with proper permitting from the Corps. This decision underscored regulatory distinctions between different types of pollutants under federal law, emphasizing agency discretion in interpreting statutory provisions related to environmental protection.
