(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.(4) "Integrated facility" means a facility where manufacturing of a product at a single physical location includes electroplating as only one of several operations and produces significant quantities of process wastewater from nonelectroplating manufacturing operations and in which one or more plant electroplating process wastewater lines are combined prior to or at the point of treatment (or proposed treatment) with one or more plant sewers carrying nonelectroplating process wastewater.(5) "New source" means any building, structure, facility or installation from which there is or may be a discharge of pollutants, the construction of which commenced after August 31, 1982.(6) "Strong chelating agents" means compounds which form soluble metal complexes which are not removed by subsequent metals control techniques such as pH adjustment followed by clarification or filtration.
(7) "TTO" means total toxic organics, which is the sum of all quantifiable values greater than 0.01 milligrams per liter (10 micrograms per liter) of the toxic organics listed in s. NR 215.03(1) to (5).Wis. Admin. Code Department of Natural Resources § NR 260.03
