(1) "Cyanide, A" means cyanide
				amenable to alkaline chlo-rination as determined by ch. NR 219.
(2) "Captive facility" means a facility which
				owns more than 50% (annual area basis) of the materials undergoing
				electroplating.
(3) "Electroplating
				process wastewater" means wastewater generated in the operations defined below
				and listed in s.
				NR
				260.02(1).
(a) "Electroplating of common metals" means
				any step in a process in which a ferrous or nonferrous basis metal is
				electroplated with copper, nickel, chromium, zinc, tin, cadmium, iron,
				aluminum, or a combination thereof and which is followed by a rinse; this
				includes the related operations of alkaline cleaning, acid pickling, stripping,
				and coloring.
(b) "Electroplating
				of precious metals" means any step in a process in which a ferrous or
				nonferrous basis metal is electroplated with gold, silver, iridium, palladium,
				platinum, rhodium, ruthenium or combination thereof and which is followed by a
				rinse; this includes the related operations of alkaline cleaning, acid
				pickling, stripping, and coloring.
(c) "Electroplating of specialty metals"
				means any step in which a ferrous or nonferrous basis metal is electroplated
				with a metal not used in par. (a) or (b) which is followed by a rinse.
(d) "Anodizing" means any step in
				the production of a protective oxide film on a ferrous or nonferrous metal
				which passes an electric current through a bath where the metal is suspended
				and is followed by a rinse; this includes the related operations of cleaning
				and coloring.
(e) "Coating" means
				the processes of chromating, phosphat-ing, or immersion plating of ferrous or
				nonferrous materials in which a basis material surface is acted upon by a
				process solution which is followed by a rinse; this includes the related
				operations of alkaline cleaning, acid pickling and sealing.
(f) "Chemical etching and milling" means any
				step in the process of etching or milling of ferrous or nonferrous material in
				which metal is chemically or electrochemically removed from the work piece and
				is followed by a rinse; this includes the related metal cleaning operations
				which precede chemical etching or milling.
(g) "Electroless plating" means any step in a
				process in which a metallic layer is deposited on a metallic or nonmetallic
				basis material and which is followed by a rinse; this includes the related
				operations of alkaline cleaning, acid pickling and stripping.
(h) "Printed circuit manufacturing" means any
				step in the process of converting an insulating substrate to a finished printed
				circuit board in which the board is immersed in an aqueous process bath which
				is followed by a rinse.
