NR 422.135(2)(a)(a) No owner or operator of a molded wood parts or products coating facility which uses flow coating to apply topcoats may cause, allow or permit the emission of any VOCs in excess of the limitations specified in Table 3.

NR 422.135(2)(b)(b) No owner or operator of a molded wood parts or products coating facility which applies a topcoat using any application method other than flow coating may cause, allow or permit the emission of any VOCs in excess of the limitations specified in Table 4.

NR 422.14(1)(a)(a) Subsections (2), (3), and (5) apply to the printing lines of all packaging rotogravure, publication rotogravure, and flexographic printing facilities that are either of the following:

NR 422.14(1)(a)1.1. Located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Washington, or Waukesha and which have maximum theoretical emissions of VOC from the facility greater than or equal to 25 tons per year.

NR 422.14(1)(a)2.2. Located outside of the counties of Kenosha, Milwaukee, Ozaukee, Racine, Washington, and Waukesha and which have maximum theoretical emissions of VOC from the facility greater than or equal to 100 ton per year.

NR 422.14(1)(b)(b) Except as provided in sub. (1m), subs. (4) and (5) apply to the owner or operator of any rotogravure printing press, except flexible packaging rotogravure, or any flexographic printing press, except flexible packaging flexographic, at a facility located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington, or Waukesha, if VOC emissions from all industrial cleaning operations, before consideration of controls, equal or exceed 3 tons per year on a 12 consecutive month rolling basis.

NR 422.14(1m)(1m) Exemptions. The following exemptions are applicable to various provisions of this section:

NR 422.14(1m)(a)(a) Subsection (4) does not apply to the stripping of cured coatings or cured inks.

NR 422.14(1m)(b)(b) Subsection (4) (a) does not apply to cleaning conducted in conjunction with performance laboratory testing on coatings or inks; research and development programs; and laboratory tests in quality assurance laboratories.

NR 422.14(1m)(c)(c) Subsection (4) (a) and (e) do not apply to cleaning with aerosol products if 160 fluid ounces or less of VOC-containing aerosol products are used per day for industrial cleaning operations per facility.

NR 422.14(1m)(d)(d) Subsection (4) (a), (d), (e), and (f) do not apply to digital printing.

NR 422.14(1m)(e)(e) Subsection (4) (e) does not apply to cleaning with solvents or solvent solutions in spray bottles or containers described in sub. (4) (b) 2.

NR 422.14(1m)(f)(f) Subsection (4) (e) does not apply to the cleaning of the nozzle tips of automated spray equipment systems, except for robotic systems that are programmed to spray into a closed container.

NR 422.14(2)(2) Emission limitations. No owner or operator of a packaging rotogravure, publication rotogravure or flexographic printing line may operate, or cause, allow or permit the operation of the line unless one of the following requirements is met:

NR 422.14(2)(a)(a) The volatile fraction of ink, as it is applied to the substrate, contains 25% by volume or less of VOC and 75% by volume or more of water.

NR 422.14(2)(b)(b) The ink, as it is applied to the substrate, less water, contains 60% by volume or more nonvolatile material.

NR 422.14(2)(c)(c) The owner or operator installs and operates one of the following:

NR 422.14(2)(c)1.1. A vapor recovery system which reduces the VOC emissions from the capture system by at least 90% by weight.

NR 422.14(2)(c)2.2. An incineration or catalytic oxidation system, provided that 90% by weight of the VOCs, VOC measured as total combustible carbon, which enter the incinerator or oxidation unit are oxidized to nonorganic compounds.

NR 422.14(2)(c)3.3. An alternative VOC emission reduction system demonstrated to have at least a 90% reduction efficiency, as measured across the control system, and approved by the department. Any approval granted by the department under this subdivision shall be submitted to, and will not become effective for federal purposes until approved by, the administrator or designee as a source-specific revision to the department’s state implementation plan for ozone.

NR 422.14(3)(3) Control system. The overall emission reduction efficiency of any capture system and control device used in conjunction with sub. (2) (c) shall be at least:
