NR 469.05(4)(4) Parts shall be oriented so that the solvent drains from them freely. Parts having cavities or blind holes shall be tipped or rotated before being removed from any solvent cleaning machine unless an equally effective approach has been approved by the department.

NR 469.05(5)(5) Parts baskets or parts may not be removed from any solvent cleaning machine until dripping has stopped.

NR 469.05(6)(6) During startup of each vapor cleaning machine, the primary condenser shall be turned on before the sump heater.

NR 469.05(7)(7) During shutdown of each vapor cleaning machine, the sump heater shall be turned off and the solvent vapor layer allowed to collapse before the primary condenser is turned off.

NR 469.05(8)(8) When solvent is added or drained from any solvent cleaning machine, the solvent shall be transferred using threaded or other leakproof couplings and the end of the pipe in the solvent sump shall be located beneath the liquid solvent surface.

NR 469.05(9)(9) Each solvent cleaning machine and associated controls shall be maintained as recommended by the manufacturers of the equipment or using alternative maintenance practices that have been demonstrated to the department’s satisfaction to achieve the same or better results as those recommended by the manufacturer.

NR 469.05(10)(10) Each operator of a solvent cleaning machine shall complete and pass the applicable sections of the test of solvent cleaning procedures in Table 5 if requested during an inspection by the department.

NR 469.05(11)(11) Waste solvent, still bottoms and sump bottoms shall be collected and stored in closed containers. The closed containers may contain a device that allows pressure relief, but that device may not allow liquid solvent to drain from the container.

NR 469.05(12)(12) Sponges, fabric, wood and paper products may not be cleaned.

NR 469.05(13)(13) If the solvent cleaning machine is not exempt under s. NR 423.03 (2) (a), (b), (d), (e) or (h), but is exempt under s. NR 423.03 (2) (i), it may not be operated so as to allow water to be visually detectable in solvent exiting the water separator.

NR 469.05(14)(14) If the solvent cleaning machine is not exempt under s. NR 423.03 (2) (a), (b), (d), (e), (f) or (h), but is exempt under s. NR 423.03 (2) (i), a permanent conspicuous label, summarizing the work and operational practices specified in subs. (1) to (9) and (11) to (13), shall be provided.

NR 469.06NR 469.06 Operational requirements associated with control devices for batch vapor and in-line cleaning machines. Each owner or operator of a solvent cleaning machine complying with s. NR 469.04 (2) or (3) or s. NR 469.073 or 469.077 shall comply with the requirements specified in this section.

NR 469.06(1)(1) Conduct monitoring of each control device used to comply with s. NR 469.04 as provided in s. NR 469.10.

NR 469.06(2)(2) Determine during each monitoring period whether each control device used to comply with these standards meets the requirements specified in pars. (a) to (k).

NR 469.06(2)(a)(a) If a freeboard refrigeration device is used to comply with these standards, the owner or operator shall ensure that the chilled air blanket temperature, in °F, measured at the center of the air blanket, is no greater than 30% of the solvent’s boiling point.

NR 469.06(2)(b)(b) If a reduced room draft is used to comply with these standards, the owner or operator shall comply with the following requirements:

NR 469.06(2)(b)1.1. Ensure that the flow or movement of air across the top of the freeboard area of the solvent cleaning machine or within the solvent cleaning machine enclosure does not exceed 15.2 meters per minute (50 feet per minute) at any time as measured using the procedures in s. NR 469.10 (4).

NR 469.06(2)(b)2.2. Establish and maintain the operating conditions under which the wind speed was demonstrated to be 15.2 meters per minute (50 feet per minute) or less as described in s. NR 469.10 (4).

NR 469.06(2)(c)(c) If a working-mode cover is used to comply with these standards, the owner or operator shall comply with the following requirements:

NR 469.06(2)(c)1.1. Ensure that the cover opens only for part entrance and removal and completely covers the cleaning machine openings when closed.

NR 469.06(2)(c)2.2. Ensure that the working-mode cover is maintained free of cracks, holes and other defects.

NR 469.06(2)(d)(d) If an idling-mode cover is used to comply with these standards, the owner or operator shall comply with the following requirements:

NR 469.06(2)(d)1.1. Ensure that the cover is in place whenever parts are not in the solvent cleaning machine and completely covers the cleaning machine openings when in place.
