PART 424-FERROALLOY MANUFACTURING POINT SOURCE CATEGORY--Table of Contents
 
Subpart B-Covered Electric Furnaces and Other Smelting Operations

Sec. 424.22  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):

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

[[Page 666]]

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).
