NR 273.002(1)
(1) Except as provided in
sub. (2), this chapter applies to discharges of pollutants to waters of the state and to publicly owned treatment works from the forming of nonferrous metals and nonferrous metal alloys and the associated ancillary operations.
NR 273.002(2)(b)
(b) Cadmium, chromium, gallium, germanium, indium, lithium, manganese, neodynum, or praseodymium.
NR 273.002(3)
(3) This chapter applies to discharges to waters of the state and the introduction of pollutants into publicly owned treatment works from the mechanical production of metal powders from iron, copper, aluminum, nonferrous metals, and their alloys, the forming of parts from metal powders, and the associated ancillary operations. This chapter does not apply to the production of metal powders by chemical means such as precipitation. If the metal powder is produced as the final step in refining metal, the regulations for nonferrous metals manufacturing,
ch. NR 274, apply.
NR 273.002(4)
(4) This chapter applies to any chemical of electrochemical treatment applied to the surface of the metal whenever these surface treatments are performed at the plant site where the metals are formed. If surface treatment is performed at a site other than where the metals are formed, regulations for electroplating,
ch. NR 260, or metal finishing,
ch. NR 261, apply.
NR 273.002(5)
(5) This chapter applies to casting when the casting is performed as an integral part of the metal forming process and takes place at the site where the metals are formed. When the casting does not take place where the metals are formed, the regulations for metal molding and casting,
ch. NR 256, apply.

NR 273.003(2)
(2) “Aluminum alloy” means an alloy in which aluminum is the major constituent in percent by weight.
NR 273.003(3)
(3) “Ancillary operation” means an operation performed as an integral part of the forming, such as 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.
NR 273.003(4)
(4) “Atomization” means the process by which a stream of water or gas impinges upon a molten metal stream, breaking it into droplets which solidify as powder particles.
