(b) Once classified, state surface waters shall retain their legislated classification until such time as they are reclassified in accordance with RSA 485-A:10, even if they fail to meet any or all of the general, class-specific, or toxic criteria contained in this part.
(c) Unless otherwise specifically allowed by a statute, rule, order, or permit, the following physical, chemical, and biological criteria shall apply to all surface waters:
(1) All surface waters shall be free from substances in kind or quantity that:
a. Settle to form harmful benthic deposits;
b. Float as foam, debris, scum or other visible substances;
c. Produce odor, color, taste or turbidity that is not naturally occurring and would render the surface water unsuitable for its designated uses;
d. Result in the dominance of nuisance species; or
e. Interfere with recreational activities;
(2) The level of radioactive materials in all surface waters shall not be in concentrations or combinations that would:
a. Be harmful to human, animal or aquatic life or the most sensitive designated use;
b. Result in radionuclides in aquatic life exceeding the recommended limits for consumption by humans; or
c. Exceed limits specified in EPA's national drinking water regulations or subtitle Env-Dw, whichever are more stringent; and
