PART 471--NONFERROUS METALS FORMING AND METAL POWDERS POINT SOURCE CATEGORY--Table of Contents
 
Sec. 471.01  Applicability.

    (a) This part applies to discharges of pollutants to waters of the 
United States and introduction of pollutants into a publicly owned 
treatment works from the forming of nonferrous metals (including 
nonferrous metal alloys), except beryllium, copper, and aluminum and 
their alloys. Aluminum alloys are defined as any alloy in which aluminum 
is the major constituent in percent by weight. Copper alloys are defined 
as any alloy in which copper is the major constituent in percent by 
weight except when copper is alloyed with precious metals. Any copper-
precious metal alloy containing 30 percent or greater precious metal is 
considered a precious metal alloy for the purposes of this part. 
Beryllium alloys are any alloy in which beryllium is present at 0.1 
percent or greater. This part applies to:
    (1) Forming operations, including rolling (both hot and cold), 
extruding, forging, drawing, swaging, cladding, and tube reducing, and
    (2) Ancillary operations performed as an integral part of the 
forming of these metals, including casting for subsequent forming, heat 
treatment, surface treatment, alkaline cleaning, solvent degreasing, 
product testing, surface coating, sawing, grinding, tumbling, 
burnishing, and wet air pollution control.
    (b) This part also applies to discharges of pollutants to waters of 
the United States and introduction of pollutants into a publicly owned 
treatment works from mechanical metal powder production operations, 
forming of parts from metal powders, and associated ancillary operations 
(listed in paragraph (a)(2) of this section) of:
    (1) Iron, copper, and aluminum, and their alloys; and
    (2) The nonferrous metals and their alloys described in paragraph 
(a) of this section. This part does not regulate the production of metal 
powders by chemical means such as precipitation. The production of metal 
powder as the final step in refining metal is regulated under the 
Nonferrous Metals Manufacturing Point Source Category regulation, 40 CFR 
part 421.
    (c) Surface treatment includes any chemical or electrochemical 
treatment applied to the surface of the metal. For the purposes of this 
regulation, surface treatment of metals is considered to be an integral 
part of the forming of metals whenever it is performed at the same plant 
site at which the metals are formed. Such surface treatment operations 
are not regulated under the Electroplating or Metal Finishing Point 
Source Category regulations, 40 CFR part 413 or 433, respectively.
    (d) Casting is covered by this part when it is performed as an 
integral part of the metal forming process and takes place at the same 
plant site at which metals are formed. Such casting will not be 
regulated under the provisions of Metal Molding and Casting Point Source 
Category regulations, 40 CFR part 464.
    (e) This part does not apply to the forming of the metals cadmium, 
chromium, gallium, germanium, indium, lithium, manganese, neodymium, or 
praseodymium.
