Water Quality Standards Regulations: Confederated Salish and Kootenai Tribes of the Flathead Reservation

Presented are water quality standards in effect for Clean Water Act (CWA) purposes.

EPA is posting these standards as a convenience to users and has made a reasonable effort to assure their accuracy. Also, for each document listed under "Tribe Standards in Effect for CWA Purposes", EPA has made a reasonable effort to identify parts of the standards that are disapproved or are otherwise not in effect for CWA purposes.

Authority to Administer Standards Program

This tribe was granted treatment in a manner similar to a state (TAS) on March 1, 1995.

Tribe Standards in Effect for CWA Purposes

The tribe’s initial water quality standards were approved on March 18, 1996. The Tribes' water quality standards are applicable to "waters of the Tribe". In some limited instances, the definition adopted by the Confederated Salish and Kootenai Tribes for "waters of the Tribe" as part of its water quality standards may result in water quality standards that are more comprehensive than required under section 303(c) of the Clean Water Act and the implementing federal regulations. EPA has included the Confederated Salish and Kootenai Tribes' water quality standards in their entirety here for context and as supplementary information for the reader.
