Operating Limits if Using the Emission Rate With Add-On Controls Option in s. NR 465.33 (2) (c)

If you are required to comply with operating limits by s. NR 465.33 (3) (b), you shall comply with the applicable operating limits in the following table.

Table 2

Default Organic HAP Mass Fraction for Solvents and Solvent Blends

You may use the mass fraction values in the following table for solvent blends for which you do not have test data or manufacturer’s formulation data and which match either the solvent blend name or the chemical abstract series (CAS) number. If a solvent blend matches both the name and CAS number for an entry, that entry’s organic HAP mass fraction shall be used for that solvent blend. Otherwise, use the organic HAP mass fraction for the entry matching either the solvent blend name or CAS number, or use the organic HAP mass fraction from Table 3 of this subchapter if neither the name or CAS number match.

Table 3

Default Organic HAP Mass Fraction for Petroleum Solvent Groups a

You may use the mass fraction values in the following table for solvent blends for which you do not have test data or manufacturer’s formulation data.

a Use this table only if the solvent blend does not match any of the solvent blends in Table 2 by either solvent blend name or CAS number and you only know whether the blend is aliphatic or aromatic.

subch. V of ch. NR 465 Subchapter V — Surface Coating of Miscellaneous Metal Parts and Products

NR 465.41 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) (2) Am i subject to this subchapter?

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).

NR 465.41(2)(a)6. 6. The extreme performance fluoropolymer coatings sub-category includes surface coating operations that are performed using coatings that meet the definition of extreme performance fluoropolymer coatings in 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.

NR 465.41(2)(c) (c) This subchapter does not apply to surface coating or a coating operation that meets any of the criteria of subds. 1. to 17.

NR 465.41(2)(c)1. 1. A coating operation conducted at a facility where the facility uses only coatings, thinners and other additives, and cleaning materials that contain no organic HAP, as determined according to s. NR 465.46 (2) (a).

NR 465.41(2)(c)2. 2. Surface coating operations that occur at research or laboratory facilities, or are part of janitorial, building and facility maintenance operations, or that occur at hobby shops that are operated for noncommercial purposes.
