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

40 CFR part 63, Subpart IIII, and you perform surface coating of metal parts or products that meets both the applicability criteria in
40 CFR 63.3082(c) and the applicability criteria of this subchapter, then, for the surface coating of any or all of your metal parts or products that meets the applicability criteria in
40 CFR 63.3082(c), you may choose to comply with the requirements of
40 CFR part 63, Subpart IIII, in lieu of complying with the requirements in this subchapter. Surface coating operations on metal parts or products not intended for use in automobiles or light-duty trucks, such as parts for motorcycles or lawn mowers, cannot be made part of your affected source under
40 CFR part 63, Subpart IIII.
NR 465.41(2)(e)
(e) If you own or operate an affected source that meets the applicability criteria of this subchapter and at the same facility you also perform surface coating that meets the applicability criteria of any other final surface coating NESHAP in
40 CFR part 63 or this chapter, you may choose to comply as specified in
subd. 1.,
2. or
3.
NR 465.41(2)(e)1.
1. You may have each surface coating operation that meets the applicability criteria of a separate NESHAP comply with that NESHAP separately.
NR 465.41(2)(e)2.
2. You may comply with the emission limit representing the predominant surface coating activity at your facility, as determined according to
subd. 2. a. and
b. However, you may not establish high performance, rubber-to-metal or extreme performance fluoropolymer coating operations as the predominant activity. You may not consider any surface coating activity that is subject to the surface coating of automobiles and light-duty trucks NESHAP in
40 CFR part 63, Subpart IIII, in determining the predominant surface coating activity at your facility.
NR 465.41(2)(e)2.a.
a. If a surface coating operation accounts for 90% or more of the surface coating activity at your facility, which is the predominant activity, then compliance with the emission limits of the predominant activity for all surface coating operations, as provided in
s. NR 465.43 (1) (c) 1., constitutes compliance with these and other applicable surface coating NESHAP. In determining predominant activity, you shall include coating activities that meet the applicability criteria of other surface coating NESHAP and constitute more than one percent of total coating activities at your facility. Coating activities that meet the applicability criteria of other surface coating NESHAP but comprise less than one percent of coating activities need not be included in the determination of predominant activity but shall be included in the compliance calculation.
NR 465.41(2)(e)2.b.
b. You shall use liters (gallons) of solids used as a measure of relative surface coating activity over a representative period of operation. You may estimate the relative volume of coating solids used from parameters other than coating consumption and volume solids content, such as design specifications for the parts or products coated and the number of items produced. The determination of predominant activity shall accurately reflect current and projected coating operations and shall be verifiable through appropriate documentation. The use of parameters other than coating consumption and volume solids content shall be approved by the administrator. You may use data for any reasonable time period of at least one year in determining the relative amount of coating activity, as long as they represent the way the source will continue to operate in the future and are approved by the administrator. You shall determine the predominant activity at your facility and submit the results of that determination with the initial notification required by
s. NR 465.45 (1) (b). You shall also determine predominant activity annually and include the determination in the next semi-annual compliance report required by
s. NR 465.45 (2) (a).
NR 465.41(2)(e)3.
3. You may comply with a facility-specific emission limit, as provided in
s. NR 465.43 (1) (c) 2., calculated from the relative amount of coating activity that is subject to each emission limit. If you elect to comply using the facility-specific emission limit alternative, then compliance with the facility-specific emission limit and the emission limits specified in
s. NR 465.43 (1) (a) and
(b) for all surface coating operations constitutes compliance with this and other applicable surface coating NESHAP. In calculating a facility-specific emission limit, you shall include coating activities that meet the applicability criteria of other surface coating NESHAP and constitute more than one percent of total coating activities at your facility. You may not consider any surface coating activity that is subject to the surface coating of automobiles and light-duty trucks NESHAP in
40 CFR part 63, Subpart IIII in determining a facility-specific emission limit for your facility. Coating activities that meet the applicability criteria of other surface coating NESHAP but comprise less than one percent of total coating activities need not be included in the calculation of the facility-specific emission limit but shall be included in the compliance calculations.
