    a     Refer to NAC 445A.122 and 445A.1432 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.
