This subchapter also establishes requirements to demonstrate initial and continuous compliance with the emission limits in
s. NR 465.33 (1).
NR 465.31 Note
Note: This subchapter is based on the federal regulations contained in
40 CFR part 63 Subpart PPPP, as last revised April 26, 2004.
NR 465.31(2)(a)(a) Plastic parts and products includes plastic components of the following types of products as well as the products themselves: motor vehicle parts and accessories for automobiles, trucks, recreational vehicles; sporting and recreational goods; toys; business machines; laboratory and medical equipment; and household and other consumer products. Except as provided in
par. (c), the source category to which this subchapter applies is the surface coating of any plastic parts or products, as described in
subd. 1., and includes the sub-categories listed in
subds. 2. to
5.
NR 465.31(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 465.31(2)(a)2.
2. The general use coating sub-category includes all surface coating operations that are not automotive lamp coating operations, thermoplastic olefin (TPO) coating operations or assembled on-road vehicle coating operations.
NR 465.31(2)(a)3.
3. The automotive lamp coating sub-category includes the surface coating of plastic components of the body of an exterior automotive lamp, including head lamps, tail lamps, turn signals and marker lamps; typical coatings used are reflective agent coatings and clear topcoats. This sub-category does not include the coating of interior automotive lamps, such as dome lamps and instrument panel lamps.
NR 465.31(2)(a)4.
4. The TPO coating sub-category includes the surface coating of TPO substrates; typical coatings used are adhesion promoters, color coatings, clear coatings and topcoats. The coating of TPO substrates on fully assembled on-road vehicles is not included in the TPO coating sub-category.
NR 465.31(2)(a)5.
5. The assembled on-road vehicle coating sub-category includes surface coating of fully assembled motor vehicles and trailers intended for on-road use, including automobiles, light-duty trucks, heavy duty trucks and buses that have been repaired after a collision or otherwise repainted; fleet delivery trucks; and motor homes and other recreational vehicles, including camping trailers and fifth wheels. This sub-category also includes the incidental coating of parts that are removed from the fully assembled on-road vehicle to facilitate concurrent coating of all parts associated with the vehicle. The assembled on-road vehicle coating sub-category does not include the surface coating of plastic parts prior to their attachment to an on-road vehicle on an original equipment manufacturer's assembly line. The assembled on-road vehicle coating sub-category also does not include the use of adhesives, sealants and caulks used in assembling on-road vehicles. Body fillers used to correct small surface defects and rubbing compounds used to remove surface scratches are not considered coatings subject to this subchapter.
NR 465.31(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 378 liters (100 gallons) per year, or more, of coatings that contain hazardous air pollutants (HAP) in the surface coating of plastic 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 in
s. NR 465.32 (27) in determining whether you use 378 liters (100 gallons) per year, or more, of coatings in the surface coating of plastic parts and products.

40 CFR part 63, Subpart IIII.
NR 465.31(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 465.31(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 465.31(2)(e)2.
2. You may comply with the emission limit in
s. NR 465.33 (1) representing the predominant surface coating activity at your facility, as determined according to
subd. 2. a. and
b. However, you may not establish assembled on-road vehicle or automotive lamp 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 465.31(2)(e)2.a.
a. If a surface coating operation accounts for 90% or more of the surface coating activity at your facility, then that is the predominant activity and compliance with the emission limits specified in
s. NR 465.33 (1) of the predominant activity for all surface coating operations 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 465.31(2)(e)2.b.
b. You shall use kilograms (kg) (pounds (lb)) of solids used as a measure of relative surface coating activity over a representative period of operation. You may estimate the relative mass of coating solids used from parameters other than coating consumption and mass solids content. 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 mass 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 465.35 (1) (b). You shall also determine predominant activity annually and include the determination in the next semi-annual compliance report required by
s. NR 465.35 (2) (a).
NR 465.31 Note
Note: An example of parameters other than coating consumption and mass solids content for estimating the relative mass of coating solids used would be design specifications for the parts or products coated and the number of items produced.
NR 465.31(2)(e)3.
3. You may comply with a facility-specific emission limit calculated according to
s. NR 465.33 (1) (c) 2. from the relative amount of coating activity that is subject to each emission limit in
s. NR 465.33 (1) (a) and
(b). If you elect to comply using the facility-specific emission limit alternative, then compliance with the facility-specific emission limit and the emission limits in
s. NR 465.33 (1) (a) and
(b) for all surface coating operations constitutes compliance with this subchapter 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.
