§ 93.4a. Antidegradation.

(b) Established fool around with security getting epidermis seas. Existing instream drinking water spends together with level of drinking water quality expected to guard current uses are going to be handled and you will protected.

(c) Security getting Quality Seas -Water quality of Top quality Waters should be maintained and you will secure, except while the provided during the § 93.4c(b)(1)(iii) (according to implementation of antidegradation conditions).
