 Subpart B_Covered Electric Furnaces and Other Smelting Operations With 

              Wet Air Pollution Control Devices Subcategory

 

Sec.  424.23  Effluent limitations guidelines representing the degree of 

effluent reduction attainable by the application of the best available 

technology economically achievable.



    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 after application of the best available technology economically 

achievable:

Provided, however, That for nonelectric furnace smelting processes, the 

units of effluent limitations set forth in this section shall be read as 

``kg/kkg of product'' rather than ``kg/Mwh,'' and the limitations 

(except for pH) shall be 3.3 times those listed in the table in this 

section (or, for English units, ``lb/ton of product'' rather than ``lb/

Mwh,'' and the limitations (except for pH) shall be three times those 

listed in the table).
