^a     Refer to NAC 445A.122 and 445A.1332 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.
