NR 465.41 What this subchapter covers. NR 465.41(1)
(1)
What is the purpose of this subchapter? This subchapter establishes national emission standards for hazardous air pollutants (NESHAP) for miscellaneous metal parts and products surface coating facilities. This subchapter also establishes requirements to demonstrate initial and continuous compliance with the emission limits specified in
s. NR 465.43 (1).
NR 465.41 Note
Note: This subchapter is based on the federal regulations contained in
40 CFR part 63 Subpart MMMM, as last revised April 26, 2004.
NR 465.41(2)(a)(a) Miscellaneous metal parts and products include metal components of the following types of products as well as the products themselves: motor vehicle parts and accessories, bicycles and sporting goods, recreational vehicles, extruded aluminum structural components, railroad cars, heavy duty trucks, medical equipment, lawn and garden equipment, electronic equipment, magnet wire, steel drums, industrial machinery, metal pipes, and numerous other industrial, household and consumer products. Except as provided in
par. (c), the source category to which this subchapter applies is the surface coating of any miscellaneous metal parts or products, as described in
subd. 1., and it includes the sub-categories listed in
subds. 2. to
6.
NR 465.41(2)(a)1.
1. Surface coating is the application of coating to a substrate. When application of coating to a substrate occurs, then surface coating also includes associated activities, such as surface preparation, cleaning, mixing and storage. However, these activities do not comprise surface coating if they are not directly related to the application of the coating. Coating application with hand-held, non-refillable aerosol containers, touch-up markers, marking pens or the application of paper film or plastic film which may be pre-coated with an adhesive by the manufacturer are not coating operations for the purposes of this subchapter.
NR 465.41(2)(a)2.
2. The general use coating sub-category includes all surface coating operations that are not high performance, magnet wire, rubber-to-metal or extreme performance fluoropolymer coating operations.
NR 465.41(2)(a)3.
3. The high performance coating sub-category includes surface coating operations that are performed using coatings that meet the definition of high performance architectural coating or high temperature coating in
s. NR 465.42 (22).
NR 465.41(2)(a)4.
4. The magnet wire coating sub-category includes surface coating operations that are performed using coatings that meet the definition of magnet wire coatings in
s. NR 465.42 (26).
NR 465.41(2)(a)5.
5. The rubber-to-metal coatings sub-category includes surface coating operations that are performed using coatings that meet the definition of rubber-to-metal coatings in
s. NR 465.42 (39).

s. NR 465.42 (18).
NR 465.41(2)(b)
(b) You are subject to this subchapter if you own or operate a new, reconstructed or existing affected source, as defined in
sub. (3), that uses 946 liters (250 gallons) per year, or more, of coatings that contain hazardous air pollutants (HAP) in the surface coating of miscellaneous metal parts and products defined in
par. (a); and that is a major source, is located at a major source or is part of a major source of emissions of HAP. A major source of HAP emissions is any stationary source or group of stationary sources located within a contiguous area and under common control that emits or has the potential to emit any single HAP at a rate of 9.07 megagrams (Mg) (10 tons) or more per year or any combination of HAP at a rate of 22.68 Mg (25 tons) or more per year. You do not need to include coatings that meet the definition of non-HAP coating contained in
s. NR 465.42 (31) in determining whether you use 946 liters (250 gallons) per year, or more, of coatings in the surface coating of miscellaneous metal parts and products.
