 Subpart B_Covered Electric Furnaces and Other Smelting Operations With 

              Wet Air Pollution Control Devices Subcategory

 

Sec.  424.20  Applicability; description of the covered electric furnaces 

and other smelting operations with wet air pollution control devices subcategory.





    The provisions of this subpart are applicable to discharges 

resulting from the smelting of ferroalloys in covered electric furnaces 

or other smelting operations, not elsewhere included in this part, with 

wet air pollution control devices. This subcategory includes those 

electric furnaces of such construction or configuration (known as 

covered,

closed, sealed, semi-covered or semi-closed furnaces) that the furnace 

off-gases are not burned prior to collection and cleaning, and which 

off-gases are cleaned after collection in a wet air pollution control 

device such as a scrubber, 'wet' baghouse, etc. This subcategory also 

includes those non- electric furnace smelting operations, such as 

exothermic (i.e., aluminothermic or silicothermic) smelting, 

ferromanganese refining, etc., where these are controlled for air 

pollution by wet air pollution control devices. This subcategory does 

not include noncontact cooling water or those furnaces which utilize dry 

dust collection techniques, such as dry baghouses.
