Water: Anti-Degradation

Pueblo of San Juan

Water Quality Standards for Tribes


Pueblo of San Juan -Water Quality Standards
SECTION II. Antidegradation Policy and Implementation Plan

Effective September 28, 1992 (revised March 11, 1998)

A. Antidegradation Policy
  1. Existing uses shall be protected. The level of water quality necessary to protect existing uses shall be maintained.
  2. Where existing water quality exceeds levels necessary to support propagation of fish and wildlife and recreation in and on the water, that level of water quality shall nonetheless be maintained and protected unless it is found, after full satisfaction of governmental and public participation requirements, that a lower level of water quality is required in order to accommodate important economic or social development in the area in which the waters are located. In allowing such degradation of water quality, the PUEBLO OF SAN JUAN shall impose the highest statutory and regulatory requirements for point sources and shall impose best management practices for nonpoint sources.
  3. Where high quality waters constitute an outstanding national or tribal resource, or waters of exceptional recreational or ecological significance, the water quality and uses of those water bodies shall be maintained and protected.
  4. In those cases where potential water quality impairments associated with thermal discharge are involved, the antidegradafion policy and implementation method shall be consistent with Section 316 of the Clean Water Act, as amended, (33 U.S.C. Section 1326 (1987)).
