Sec. 463.22  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 cleaning water processes at a point source times the following 

pollutant concentrations:
