Section NR 465.31 - What this subchapter covers
Universal Citation: WI Admin Code ยง NR 465.31
Current through August 26, 2024
(1) WHAT IS THE PURPOSE OF THIS SUBCHAPTER? This subchapter establishes national emission standards for hazardous air pollutants (NESHAP) for plastic parts and products surface coating facilities. This subchapter also establishes requirements to demonstrate initial and continuous compliance with the emission limits in s. NR 465.33(1).
Note: This subchapter is based on the federal regulations contained in 40 CFR part 63 Subpart PPPP, as last revised April 26, 2004.
(2) AM I SUBJECT TO THIS SUBCHAPTER?
(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.
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.
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.
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.
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.
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.
(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.
(c) This subchapter does not apply to surface
coating or a coating operation that meets any of the criteria of subds. 1. to
16.
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).
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.
3. The
surface coating of plastic parts and products performed on-site at
installations owned or operated by the armed forces of the United States,
including the Coast Guard and the National Guard of any state, or the National
Aeronautics and Space Administration, or the surface coating of military
munitions manufactured by or for the armed forces of the United States,
including the Coast Guard and the National Guard of any state.
4. Surface coating where plastic is extruded
onto plastic parts or products to form a coating.
5. Surface coating of magnet wire.

40 CFR part 63, Subpart II.
14.
Surface coating of plastic using a web coating process that meets the
applicability criteria for paper and other web coating in 40 CFR part 63,
Subpart JJJJ.
15. Surface coating
of fiberglass boats or parts of fiberglass boats, including the use of assembly
adhesives, where the facility meets the applicability criteria for boat
manufacturing, 40 CFR part 63, Subpart VVVV, except where the surface coating
of the boat is a post-mold coating operation performed on personal watercraft
or parts of personal watercraft. This subchapter does apply to post-mold
coating operations performed on personal watercraft and parts of personal
watercraft.
16. Surface coating of
plastic components of automobiles and light-duty trucks that meet the
applicability criteria in
40 CFR
63.3082(b) of the surface
coating of automobiles and light-duty trucks NESHAP in 40 CFR part 63, Subpart
IIII, at a facility that meets the applicability criteria in
40 CFR
63.3081(b).
(d) If your facility meets the
applicability criteria in
40 CFR
63.3081(b) of the surface
coating of automobiles and light-duty trucks NESHAP in 40 CFR part 63, Subpart
IIII, and you perform surface coating of plastic 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 plastic 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 this subchapter. Surface coating operations on plastic 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.
(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.
1. You may have each surface coating
operation that meets the applicability criteria of a separate NESHAP comply
with that NESHAP separately.
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.
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.
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).
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.
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.
