Sec. 463.12  Effluent limitations guidelines representing the degree 



of effluent reduction attainable by the application of the best 

practicable control 

          technology currently available.



    Except as provided in 40 CFR 125.30 through 125.32, any existing 

point source subject to this subpart must

achieve the effluent limitations guidelines (i.e., mass of pollutant 

discharged) representing the degree of effluent reduction attainable by 

the application of the best practicable control technology currently 

available, which are calculated by multiplying the average process water 

usage flow rate for the contact cooling and heating water processes at a 

point source times the following pollutant concentrations:
