a Refer to NAC 445A.122 and 445A.1432 for beneficial use terminology.
b Maximum allowable increase in temperature above water temperature at the boundary of an approved mixing zone, but the increase must not cause a violation of the single value standard.
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.
