NR 422.14(4)(d)(d) Control equipment. In lieu of complying with the requirements in pars. (a) and (b), the owner or operator of a facility may use a VOC emission control system to control VOC emissions from the industrial cleaning operations at the facility provided one of the following requirements is met:

NR 422.14(4)(d)1.1. The emission control system has a minimum overall emission reduction efficiency of 85% for VOC emissions, as determined in accordance with s. NR 439.06 (3) (am).

NR 422.14(4)(d)2.2. The emission control system has a minimum VOC capture efficiency of 90% and an output of VOC emissions of less than 50 ppm calculated as carbon, not including methane and ethane, with no dilution, as determined in accordance with s. NR 439.06 (3) (a).

NR 422.14(4)(e)(e) General prohibitions. The owner or operator of a facility may not atomize any solvent or solvent solution unless the resulting VOC emissions are controlled by an air pollution control system that meets one of the requirements of par. (d).

NR 422.14(4)(f)(f) Alternative compliance option. In lieu of complying with the requirements in par. (a), the owner or operator of a facility may use solvents or solvent solutions for industrial cleaning operations which have a VOC composite partial vapor pressure of less than or equal to 8 mm of Hg at 20°C.

NR 422.14(5)(5) Recordkeeping. In addition to the applicable recordkeeping requirements in s. NR 439.04, the owner or operator of any packaging rotogravure, publication rotogravure or flexographic printing facility shall collect and record the applicable information specified in this subsection. The information shall be maintained at the facility for a minimum of 5 years and shall be made available to a department representative at any time during normal working hours. The information required is:

NR 422.14(5)(a)(a) For each operation that is exempt under sub. (1m) (c), the daily quantity in fluid ounces of VOC-containing aerosol product used for industrial cleaning operations.

NR 422.14(5)(b)(b) For each operation that is subject to sub. (4), the following information as appropriate:

NR 422.14(5)(b)2.2. The VOC content of each cleaning material, in pounds per gallon of material, as employed or the VOC composite partial vapor pressure of the solvents or solvent solutions used in industrial cleaning operations.

NR 422.141(1)(a)(a) Subsection (3) applies to the owner or operator of a flexible packaging press located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington, or Waukesha if VOC emissions from all flexible packaging printing presses and related flexible packaging cleaning activities at the facility, before consideration of controls, equal or exceed 3 tons on a 12 consecutive month rolling basis. When determining the VOC emissions for applicability under this paragraph, the VOC emissions from the cleaning of electronic components of a flexible packaging press, pre-press and post-press cleaning operations and the use of janitorial supplies used to clean around a flexible packaging press are excluded. In addition, the VOC emissions from solvents used in cold cleaners are excluded for applicability purposes.

NR 422.141(1)(b)(b) Subsection (2) applies to the owner or operator of a facility located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington, or Waukesha that operates a flexible packaging press that has maximum theoretical emissions of VOC equal to or greater than 25 tons per year from inks, coatings and adhesives combined, from the press dryer. For a flexible packaging press subject to sub. (2) and also to s. NR 422.14 (2), compliance with sub. (2) shall satisfy compliance with s. NR 422.14 (2).

NR 422.141(2)(2) Emission limitations. On and after May 1, 2010, no owner or operator of a flexible packaging press subject to this subsection may operate, or cause, allow or permit the operation of the press unless the owner or operator does one of the following:

NR 422.141(2)(a)(a) Installs and operates a vapor recovery system, incinerator or catalytic oxidation system to control VOC emissions. The overall VOC emission reduction efficiency of any capture system and control device, as measured across the entire control system, shall be at least:

NR 422.141(2)(a)1.1. 65% by weight for a flexible packaging press that was first installed prior to March 14, 1995 and that is controlled by a control device that was installed prior to August 1, 2009. VOC emissions from an incinerator or catalytic oxidation system shall be measured as carbon.
