Sec. 440.52  Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best practicable control 
          technology currently available (BPT).

    Except as provided in subpart L of this part and 40 CFR 125.30 
through 125.32, any existing point source subject to this subpart must 
achieve the following effluent limitations representing the degree of 
effluent reduction attainable after application of the best practicable 
control technology currently available (BPT):
    (a) The concentration of pollutants discharged in mine drainage from 
mines obtaining titanium ores from lode deposits shall not exceed:
