Water Quality Standards Regulations: Confederated Tribes of the Warm Springs Indian Reservation of Oregon

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

The EPA is posting these standards as a convenience to users and has made a reasonable effort to assure their accuracy. For each document listed under "Tribal Standards in Effect for CWA Purposes", the EPA has made a reasonable effort to identify parts of the standards that are disapproved or are otherwise not in effect for CWA purposes. Additionally, please note the documents may also contain provisions that the EPA does not have the authority and duty to act on under the Clean Water Act because the provisions are not water quality standards.
