Sec. 434.22  Effluent limitation guidelines representing the degree of effluent reduction attainable by the application of the best practicable control 
          technology currently available (BPT).

    (a) Except as provided in 40 CFR 125.30-125.32, 40 CFR 401.17, and 
Secs. 434.61, 434.62 and 434.63 of this part, the following limitations 
establish the concentration or quality of pollutants which may be 
discharged by any existing coal preparation plant and coal preparation 
plant associated areas subject to the provisions of this subpart after 
application of the best practicable control technology currently 
available if discharges from such point sources normally exhibit a pH of 
less than 6.0 prior to treatment:
