      Subpart F-Electrolytic Manganese Products Subcategory
 
Sec. 424.62  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 Sec.Sec. 125.30 through 
125.32, any existing point source subject to this subpart shall achieve 
the following effluent limitations representing the degree of effluent 
reduction attainable by the application of the best practicable control 
technology currently available (BPT):
    (a) The following limitations establish the quantity or quality of 
pollutants or pollutant properties, controlled by this section which may 
be discharged by a point source subject to the provisions of this 
subpart producing electrolytic manganese after application of the best 
practicable control technology currently available:
