      CHAPTER I-ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 424-FERROALLOY MANUFACTURING POINT SOURCE CATEGORY--Table of Contents
 
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).
