(7) (d). NR 423.03(2)(h)(h) This section does not apply to solvent metal cleaning operations using only cleaning solvents that have a VOC content of 2.0% or less by volume. NR 423.03(2)(i)(i) This section does not apply to any individual cold cleaning, batch vapor degreasing or conveyorized degreasing operation that is subject to ch. NR 469. NR 423.03(3)(3) Cold cleaners. Except as provided under sub. (2) (a), (b), (c), (h) and (i), the owner or operator of a cold cleaning facility shall do all of the following: NR 423.03(3)(b)(b) Design the cover so that it can be easily operated with one hand if any of the following applies: NR 423.03(3)(b)1.1. The solvent volatility is greater than 2 kPa (0.3 psia) measured at 38°C (100°F). NR 423.03(3)(c)(c) Equip the cleaner with a facility for draining cleaned parts, and the drainage facility shall be constructed internally so that parts are enclosed under the cover while draining if the solvent volatility is greater than 4.3 kPa (0.6 psia) measured at 38ºC (100°F), except that the drainage facility may be external for applications where an internal type cannot fit into the cleaning system. NR 423.03(3)(d)(d) Install one of the following control devices if the solvent volatility is greater than 4.3 kPa (0.6 psia) measured at 38°C (100°F), or if the solvent is heated above 49°C (120°F): NR 423.03(3)(d)1.1. Freeboard that gives a freeboard ratio greater than or equal to 0.70. NR 423.03(3)(d)2.2. Water cover (solvent must be insoluble in and heavier than water). NR 423.03(3)(d)3.3. Other systems of equivalent control, such as refrigerated chiller or carbon adsorption, approved by the department. NR 423.03(3)(e)(e) If used, supply a solvent spray that is a solid fluid stream (not a fine, atomized or shower type spray) at a pressure which does not cause extensive splashing. NR 423.03(3)(f)(f) Provide a permanent, conspicuous label, summarizing the operating requirements. NR 423.03(3)(g)(g) Provide supervision or instruction adequate to ensure that the operation is conducted in accord with all of the following: NR 423.03(3)(g)1.1. Close the cover whenever parts are not being handled in the cleaner. NR 423.03(3)(g)2.2. Drain the cleaned parts for at least 15 seconds or until dripping ceases. NR 423.03(3)(g)3.3. Store waste solvent only in covered containers and not dispose of waste solvent or transfer it to another person in such a way as to cause greater than 15% of the waste solvent, by weight, to evaporate into the ambient air during the ozone season, s. NR 419.04 notwithstanding. NR 423.03(3)(g)4.4. Repair solvent leaks immediately, or shut down the degreaser until the leaks are repaired. NR 423.03(3)(h)(h) Design the cover so that it is either a roll-top cover, a canvas curtain cover, a guillotine (biparting) cover, or any other type of cover that slides off the degreaser in a horizontal motion and is designed such that it can be opened or closed without disturbing the vapor layer or the solvent surface if any of the following applies: NR 423.03(3)(h)1.1. The solvent volatility is greater than 2 kPa (0.3 psia) measured at 38°C (100°F).
