This section applies to facilities which are located in the county of Kenosha, Milwaukee, Ozaukee, Racine, Sheboygan, Washington or Waukesha and have VOC emissions, before consideration of controls, equal to or exceeding 3 tons on a 12 consecutive month rolling basis from large appliance surface coating, including any related cleaning activities. For purposes of this section, coatings include paints, sealants, caulks, inks, adhesives, and maskants, but do not include metal protection oils, acids and bases.

(2)   Exemptions. The following coating types are exempt from the emission limitations in sub. (3) :

(a) Stencil coatings.

(b) Safety-indicating coatings.

(c) Solid-film lubricants.

(d) Electric-insulating and thermal-conducting coatings.

(e) Touch-up and repair coatings.

(f) Hand-held aerosol can coatings.

(3)   Emission limitations. On and after May 1, 2010, no owner or operator may cause, allow or permit the emission of any VOCs in excess of limits listed in Table 2B. Notwithstanding s. NR 422.04 (4) , an owner or operator using a control device to achieve compliance with this subsection as allowed under s. NR 422.04 (2) (c) , shall achieve a minimum overall VOC control efficiency of 90%. - See PDF for table

(4)   Application equipment and methods. No owner or operator of a large appliance surface coating line subject to sub. (3) may apply coatings unless one of the following types of high transfer efficiency application equipment is used in accordance with the manufacturer's recommendations:

(a) Electrostatic application equipment.

(b) Low-pressure spray method application equipment.

(c) Flow coating.

(d) Roll coating.

(e) Dip coating, including electrodeposition.

(5)   Work practices. On and after November 1, 2009, the owner or operator of a large appliance surface coating facility shall employ work practices to minimize VOC emissions from mixing operations, storage tanks and other containers, and handling operations for coatings, thinners, cleaning materials, and waste materials. Work practices shall include all of the following, at a minimum:

(a) Store all VOC-containing coatings, thinners, coating related waste materials, cleaning materials, and shop towels used for cleaning in closed containers.

(b) Close mixing and storage vessels used for VOC-containing coatings and other materials except when depositing or removing these materials.

(c) Convey VOC-containing coatings, thinners, and cleaning materials in closed containers or pipes.
