NR 422.04(3)(b)1.1. The design, operation and efficiency of the application system must be certified in writing by the owner or operator and submitted to the department for approval.

NR 422.04(3)(b)2.2. The solvent usage per coated part for application system must be less than or equal to the solvent usage per coated part at the applicable emission limitation using baseline transfer efficiency.

NR 422.04(3)(c)(c) Each alternative control method or system approval granted by the department under this subsection 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 422.04(4)(4) Capture systems. The design, operation and efficiency of any capture system used in conjunction with sub. (2) (b), (c) or (d) shall be certified in writing by the owner or operator. The efficiency of the capture system is subject to approval by the department. For sources subject to an emission limitation under this chapter which is expressed in units of pounds VOC per gallon of coating or ink, excluding water, the efficiency of the capture system shall be great enough to insure that for any day either 95% overall control is achieved or the emissions from the controlled line are less than or equal to the amount determined using the following equation:

E is the total allowable daily emissions of VOCs in kilograms (pounds) from all coatings or inks subject to the same numerical emission limitation and applied on the controlled line

Ai is the allowable emission rate for the coatings or inks pursuant to the requirements of this chapter in kilograms per liter (pounds per gallon) of coating or ink, excluding water, delivered to the applicator

Pi is the density of the VOC used in the coating or ink delivered to the applicator during the actual production day in kilograms per liter (pounds per gallon). If the coating or ink does not contain any VOCs, or if the actual VOC density cannot be demonstrated by the owner or operator, a value of 0.88 kilograms per liter (7.36 pounds per gallon) shall be used for P.

NR 422.05(1)(a)(a) Subsections (2) and (4) apply to coating applicators and ovens of sheet, can or end coating lines involved in sheet basecoat (exterior and interior) and overvarnish; 2-piece can exterior (basecoat and overvarnish); 2- and 3-piece can interior body spray; 2-piece can exterior end (spray or roll coat); 3-piece can side-seam spray and end sealing compound operations at a facility that is either of the following:

NR 422.05(1)(a)1.1. Located in the county of Brown, Calumet, Dane, Dodge, Door, Fond du Lac, Jefferson, Kenosha, Kewaunee, Manitowoc, Milwaukee, Ozaukee, Outagamie, Racine, Rock, Sheboygan, Walworth, Washington, Waukesha, or Winnebago and which has VOC emissions from all can coating lines at the facility, before consideration of controls, exceeding 6.8 kilograms (15 pounds) in any one day.

NR 422.05(1)(a)2.2. Located outside of the counties of Brown, Calumet, Dane, Dodge, Door, Fond du Lac, Jefferson, Kenosha, Kewaunee, Manitowoc, Milwaukee, Ozaukee, Outagamie, Racine, Rock, Sheboygan, Walworth, Washington, Waukesha, and Winnebago and which has total VOC emissions from the facility, before consideration of controls, equal to or exceeding 100 tpy.

NR 422.05(1)(b)(b) Except as provided in sub. (1m), subs. (3) and (4) apply to a facility with coating operations as described in par. (a) and which is 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 422.05(1m)(b)(b) Subsection (3) (a) 4. in Table 1 does not apply to facilities using less than a total of 1.5 gallons per day of VOC-containing solvents and solvent solutions to clean sterilization indicating ink application equipment.

NR 422.05(1m)(c)(c) Subsection (3) (a) does not apply to cleaning conducted in conjunction with performance testing on coatings or inks, research and development programs, and quality assurance testing. This exemption is limited to the use of up to a total of 110 gallons of solvents and solvent solutions per year on a 12 consecutive month rolling basis.

NR 422.05(1m)(d)(d) Subsection (3) (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.
