Section NR 421.02 - Definitions

Except when another definition is specifically made applicable, the definitions contained in chs. NR 400, 419, and 420 apply to the terms used in this chapter. In addition, except when another definition is specifically made 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.
