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:
