NR 425.03 (5), to cold cleaning, open top vapor degreasing and conveyorized vapor degreasing operations. This section also applies, with a final compliance deadline of May 1, 1988, except as provided in sub. (8), to conveyorized non-vapor degreasing operations and, under the compliance provisions of sub. (8) (c), to wipe cleaning operations.
NR 423.03 NoteNote: Owners and operators of solvent cleaning operations should refer to sub. (2) (h) and (i) and ch. NR 469.
NR 423.03(2)(2)Exemptions. The owner or operator of any facility located in Kenosha, Kewaunee, Manitowoc, Milwaukee, Ozaukee, Racine, Sheboygan, Washington, or Waukesha county and which claims to be exempt under this subsection from any requirement of subs. (3) to (7) shall comply with the recordkeeping requirements of sub. (10). The following exemptions apply to the source categories indicated:
NR 423.03(2)(a)(a) This section does not apply to individual cold cleaners to which not more than 5.7 liters (1.5 gallons) of solvent is added per day, or to individual open top vapor, conveyorized vapor or conveyorized non-vapor degreasers whose emissions of VOCs are not more than 6.8 kilograms (15 pounds) in any one day provided the following conditions are met:
NR 423.03(2)(a)1.1. The degreaser is located outside the counties of Brown, Calumet, Dane, Dodge, Door, Fond du Lac, Jefferson, Kenosha, Kewaunee, Manitowoc, Milwaukee, Outagamie, Ozaukee, Racine, Rock, Sheboygan, Walworth, Washington, Waukesha, and Winnebago.
NR 423.03(2)(a)2.2. The emission rates from open top vapor and conveyorized vapor degreasers are determined and certified before October 1, 1979 in a manner approved by the department, and the emission rates from conveyorized non-vapor degreasers are determined and certified before May 1, 1988 in a manner approved by the department.
NR 423.03(2)(b)(b) This section also does not apply to sources used exclusively for chemical or physical analysis or determination of product quality and commercial acceptance where all of the following conditions are met:
