Sec. 60.161  Definitions.

    As used in this subpart, all terms not defined herein shall have the 
meaning given them in the Act and in subpart A of this part.
    (a) Primary copper smelter means any installation or any 
intermediate process engaged in the production of copper from copper 
sulfide ore concentrates through the use of pyrometallurgical 
techniques.
    (b) Dryer means any facility in which a copper sulfide ore 
concentrate charge is heated in the presence of air to eliminate a 
portion of the moisture from the charge, provided less than 5 percent of 
the sulfur contained in the charge is eliminated in the facility.
    (c) Roaster means any facility in which a copper sulfide ore 
concentrate charge is heated in the presence of air to eliminate a 
significant portion (5 percent or more) of the sulfur contained in the 
charge.
    (d) Calcine means the solid materials produced by a roaster.
    (e) Smelting means processing techniques for the melting of a copper 
sulfide ore concentrate or calcine charge leading to the formation of 
separate layers of molten slag, molten copper, and/or copper matte.
    (f) Smelting furnace means any vessel in which the smelting of 
copper sulfide ore concentrates or calcines is performed and in which 
the heat necessary for smelting is provided by an electric current, 
rapid oxidation of a portion of the sulfur contained in the concentrate 
as it passes through an oxidizing atmosphere, or the combustion of a 
fossil fuel.
    (g) Copper converter means any vessel to which copper matte is 
charged and oxidized to copper.
    (h) Sulfuric acid plant means any facility producing sulfuric acid 
by the contact process.
    (i) Fossil fuel means natural gas, petroleum, coal, and any form of 
solid, liquid, or gaseous fuel derived from such materials for the 
purpose of creating useful heat.
    (j) Reverberatory smelting furnace means any vessel in which the 
smelting of copper sulfide ore concentrates or calcines is performed and 
in which the heat necessary for smelting is provided primarily by 
combustion of a fossil fuel.
    (k) Total smelter charge means the weight (dry basis) of all copper 
sulfide ore concentrates processed at a primary copper smelter, plus the 
weight of all other solid materials introduced into the roasters and 
smelting furnaces at a primary copper smelter, except calcine, over a 
one-month period.
    (l) High level of volatile impurities means a total smelter charge 
containing more than 0.2 weight percent arsenic, 0.1 weight percent 
antimony, 4.5 weight percent lead or 5.5 weight percent zinc, on a dry 
basis.
