Antidegradation definition

Antidegradation means the regulatory actions and measures taken to prevent or minimize the lowering of water quality in surface waters of the state, including those streams, lakes, and wetlands in which existing water quality exceeds the level required for maintenance and protection of existing uses.

Antidegradation means the policy set forth in the water quality regulations under the Clean Water Act, as established by the United States Environmental Protection Agency, whereby existing and future uses and the level of water quality necessary to maintain those uses is maintained and protected. (See 40 C.F.R. ' 131.12).
Sample 1
Antidegradation means a policy to ensure that existing ground water quality (that currently is of higher quality than the water quality criteria in N.J.A.C. [7:9-6.7] 7:9C-1.7) is not degraded to the criteria by discharges, but rather remains at a better quality ranging from natural quality at the most stringent, to a limited allowance for degradation at the least stringent. “Non-degradation” is the most stringent case of the antidegradation policy. It prohibits any degradation of ground water quality below existing background water quality by a discharge.

More Definitions of Antidegradation

Antidegradation means the policy set forth in the Water Quality Standards whereby existing uses and the level of water quality necessary to maintain those uses is maintained and protected (See 40 C.F.R. Section 131.12 (1987)).
Sample 1
Antidegradation means the limitation of changes in mean water quality or quantity to protect existing and designated uses, to maintain that quality which is better than the applicable criteria, and to prevent any additional lowering of water quality or quantity where those levels are already below the criteria or levels necessary to support the existing or designated uses.
