PART 467_ALUMINUM FORMING POINT SOURCE CATEGORY--Table of Contents
 
Sec. 467.01  Applicability.

    (a) Aluminum forming includes commonly recognized forming operations 
such as rolling, drawing, extruding, and forging and related operations 
such as heat treatment, casting, and surface treatments. Surface 
treatment of aluminum is any chemical or electrochemical treatment 
applied to the surface of aluminum. Such surface treatment is considered 
to be a part of aluminum forming whenever it is performed as an integral 
part of aluminum forming. For the purposes of this regulation, surface 
treatment of aluminum is considered to be an integral part of aluminum 
forming whenever it is performed at the same plant site at which 
aluminum is formed and such operations are not considered for regulation 
under the Electroplating and Metal Finishing provisions of 40 CFR parts 
413 and 433. Casting aluminum when performed as an integral part of 
aluminum forming and located on-site at an aluminum forming plant is 
considered an aluminum forming operation and is covered under these 
guidelines. When aluminum forming is performed on the same site as 
primary aluminum reduction the casting shall be regulated by the 
nonferrous metals guidelines if there is no cooling of the aluminum 
prior to casting. If the aluminum is cooled prior to casting then the 
casting shall be regulated by the aluminum forming guidelines.
    (b) This part applies to any aluminum forming facility, except for 
plants identified under paragraph (c) of this section, which discharges 
or may discharge pollutants to waters of the United States or which 
introduces or may introduce pollutants into a publicly owned treatment 
works.
    (c) This part is applicable to indirect discharging aluminum forming 
plants that extrude less than 3 million pounds of product per year and 
draw, with emulsions or soaps, less than 1 million pounds per year.
    Note: This paragraph is promulgated as an Interim Final Rule.
