It is national policy that the Federal government, in the design, construction, management, operation, and maintenance of its facilities, shall provide leadership in the nationwide effort to protect and enhance the quality of our air, water, and land resources. Federal facilities shall comply with all Federal, State, Tribal, Interstate, and Local requirements in the same manner and extent as other entities. The national antidegradation policy, defined in the Federal water quality management laws, requires: 1)that the existing water quality of waters that constitute an outstanding national resource be maintained and protected; 2) that the existing water quality of high quality waters that supports a diverse, productive, and ecologically sound habitat be maintained and protected unless there is compelling evidence that to do so will cause significant national economic and social harm; and 3) in all cases, the existing beneficial uses and the water quality necessary to protect them will be maintained. Existing beneficial uses are defined as those beneficial uses actually attained in a water body on or after November 28, 1975, whether or not they are included in Tribal or State water quality standards (40CFR131.3e). This national policy is founded on the overall objective established in the Clean Water Act to restore and maintain the chemical, physical, and biological integrity of the nation’s waters. The thrust of this policy is to protect all existing and future uses including assimilative capacity, aquatic life, water supply, recreation, industrial use, hydropower, etc. Where uses are degraded, it is the national goal to restore those degraded waters to more productive conditions.
