X = Beneficial use.

^a     Refer to NAC 445A.122 and 445A.1282 for beneficial use terminology.

^b     The water must not contain nutrient concentrations from a source other than a natural source which cause the growth of algae or aquatic plants in amounts that interfere with any beneficial uses of the water.

^c     The ambient water quality criteria for ammonia are specified in NAC 445A.118.

^d     One-hour and 96-hour average concentration limits may be exceeded only once every 3 years.
