			  NR
			  400, 419, and 420 apply to the terms used in this

			  applicable, in this chapter and in chs.
			  NR 422 to 425:
(1) "Bead dipping" means the dipping of an
			assembled tire bead into a solvent based cement.
(2) "Blending tank" means any vessel in which
			resin, coating or other materials, or any combination thereof, are added to
			produce product blend.
(3)
			"Coatings manufacturing facility" means any facility which mixes, blends or
			compounds paints, varnishes, lacquers, enamels, shellacs or sealers, and which
			is classified under standard industrial classification code 2851, as described
			in the Standard Industrial Classification Manual, 1987, incorporated by
			reference in s.
			NR
			484.05.
(4) "Completed resin" is any resin which has
			completed its processing and is available for use in the basic components of
			plastics or as a component of surface coating formulations.
(5) "Green tires" means assembled tires
			before molding and curing have occurred.
(6) "Green tire spraying" means the spraying
			of green tires, both inside and outside, with release compounds which help
			remove air from the tire during molding and prevent the tire from sticking to
			the mold after curing.
(7)
			"Grinding mill" means any mill with cylindrical chambers containing grinding
			media such as balls, pebbles, or sand which grind and disperse coating
			solids.
(8) "High speed dispersion
			mill" means any mixer with one or more blades that rotate at high speed in
			order to disperse coating solids.
(9) "Passenger type tire" means agricultural,
			airplane, industrial, mobile home, light and medium duty truck, and passenger
			vehicle tires with a bead diameter up to 50.8 cm (20 inches) and cross section
			dimension up to 32.5 cm (12.8 inches).
(10) "Pneumatic rubber tire manufacture"
			means the production of pneumatic rubber passenger type tires on a mass
			production basis.
(11) "Production
			equipment exhaust system" means a device for collecting and directing out of
			the work area fugitive emissions from reactor openings, centrifuge openings,
			and other vessel openings at a pharmaceutical manufacturing plant.
(12) "Reaction tank" means any piece of
			equipment in which organic or other materials are reacted to produce a resin. A
			reaction tank may include a stripping column, condensers, and a water
			separator, which return the evaporated solvent to the reaction
			vessel.
(13) "Reactor" means a vat
			or vessel, which may be jacketed to permit temperature control, designed to
			contain chemical reactions.
(14)
			"Resin" means a solid or semi-solid, water-insoluble, organic material with
			little or no tendency to crystallize and which is used as the basic components
			of plastics or as a component of surface-coating formulations.
(15) "Roller mill" means any mill with
			horizontal rollers that grind and disperse coating solids.
(16) "Synthesized pharmaceutical
			manufacturing" means manufacture of pharmaceutical products by chemical
			synthesis.
(17) "Synthetic resin
			manufacturing facility" means any facility which reacts organic compounds to
			produce a synthetic resin and which is classified under standard industrial
			classification code 2821, as described in the Standard Industrial
			Classification Manual, 1987, incorporated by reference in s.
			NR
			484.05.
(18) "Thinning tank" means any vessel in
			which resin, coating, or other products are combined with solvents to thin the
			product.
(18m) "Tote tank" means
			any transportable container used to convey coatings, inks, adhesives, or any
			other related materials, with a capacity equal to or greater than 209 liters
			(55 gallons).
(19) "Tread end
			cementing" means the application of a solvent based cement to tire tread
			ends.
(20) "Undertread cementing"
			means the application of a solvent based cement to the underside of a tire
			tread.
(21) "VOC emission leak"
			means a fugitive emission of volatile organic compounds from any valve, pump,
			sealed agitator, compressor, flange or relief valve for which the fugitive VOC
			concentration is measured to exceed 10,000 ppm when tested according to Method
			21 in Appendix A of 40 CFR part 60 , incorporated by reference in s.
			NR
			484.04.
(22) "Water based sprays" means release
			compounds, sprayed on the inside and outside of green tires, in which solids,
			water, and emulsifiers have been substituted for all organic
			solvents.
(23) "Wipe cleaning"
			means cleaning which utilizes a material such as a rag wetted with a solvent,
			prior to a physical rubbing process to remove contaminants from
			surfaces.
