				  NR
				  205.03,
				  205.04 and
				  211.03.
(1) "Alkaline cleaning bath" means a bath
				consisting of an alkaline cleaning solution through which a workpiece is
				processed.
(2) "Alkaline cleaning
				rinse" means a rinse following an alkaline cleaning bath through which a
				workpiece is processed. A rinse consisting of a series of rinse tanks is
				considered as a single rinse.
(3)
				"Alkaline cleaning rinse for forged parts" means a rinse following an alkaline
				cleaning bath through which a forged part is processed. A rinse consisting of a
				series of rinse tanks is considered as a single rinse.
(4) "Ancillary operation" means an operation,
				such as surface and heat treatment, hydrotesting, sawing, and surface coating,
				associated with a primary forming operation.
(5) "Annealing with oil" means the use of oil
				to quench a workpiece as it passes from an annealing furnace.
(6) "Annealing with water" means the use of a
				water spray or bath, of which water is the major constituent, to quench a
				workpiece as it passes from an annealing furnace.
(7) "Beryllium copper alloy" means any copper
				alloy that is alloyed to contai n 0.10 % or greater beryllium.
(8) "Cold rolling" means the process of
				rolling a workpiece below the recrystallization temperature of the copper or
				copper alloy.
(9) "Drawing" means
				pulling the workpiece through a die or succession of dies to reduce the
				diameter or alter its shape.
(10)
				"Existing source" means any point source, except for a new source as defined in
				sub. (16), from which pollutants may be discharged either into waters of the
				state or into a publicly owned treatment works.
(11) "Extrusion" means the application of
				pressure to a copper workpiece, forcing the copper to flow through a die
				orifice.
(12) "Extrusion heat
				treatment" means the spray application of water to a workpiece for the purpose
				of heat treatment immediately following extrusion.
(13) "Hot rolling" means the process of
				rolling a workpiece above the recrystallization temperature of the copper or
				copper alloy.
(14) "Heat treatment"
				means the application of heat to or the removal of heat from a workpiece to
				change the physical properties of the metal.
(15) "Miscellaneous waste stream" means
				hydrotesting, sawing, surface milling, and maintenance wastestreams when they
				are related to the forming of copper.
(16) "New source", as defined for new source
				performance standards and pretreatment standards for new sources, means any
				point source for which construction commenced after November 12, 1982 and from
				which pollutants are or may be discharged directly to the waters of the state
				or to a publicly owned treatment works.
(17) "Off kilogram" and "off pound" mean the
				mass of copper or copper alloy removed from a forming or ancillary operation at
				the end of a process cycle for transfer to a different machine or
				process.
(18) "Pickling bath" means
				a chemical bath, other than an alkaline cleaning bath, through which a
				workpiece is processed.
(19)
				"Pickling fume scrubber" means an air pollution control device which removes
				particulates and fumes from air above a pickling bath by entraining the
				pollutants in water.
(20) "Pickling
				rinse" means a rinse, other than an alkaline cleaning rinse, through which a
				workpiece is processed. A rinse consisting of a series of rinse tanks is
				considered as a single rinse.
(21)
				"Pickling rinse for forged parts" means a rinse, other than an alkaline
				cleaning rinse, through which forged parts are processed. A rinse consisting of
				a series of tanks is considered as a single rinse.
(22) "Precious metals" means gold, platinum,
				palladium, silver, and their alloys when the alloy contains 30% or greater
				percent by weight of precious metals.
(23) "Primary forming operation" means hot
				rolling, cold rolling, drawing, extrusion, and forging of copper and copper
				alloys.
(24) "Rolling" means
				reducing the thickness or diameter of a workpiece by passing it between
				rollers.
(25) "Solution heat
				treatment" means introducing a workpiece into a quench bath for purposes of
				heat treatment.
(26) "Spent
				lubricant" means water or an oil and water mixture which has been used in
				forming operations to reduce friction, heat, and wear and which is
				discharged.
(27) "Surface coating"
				means the process of coating a copper workpiece, as well as the associated
				surface washing and flattening.
(28) "Total toxic organics" and "TTO" mean
				the sum of the masses or concentrations of each of the following organic
				compounds which is found at a concentration greater than 0.010 mg/l:
anthracene
