Universal Citation: WI Admin Code ยง NR 465.41
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 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).
Note: This subchapter is based on the federal regulations contained in 40 CFR part 63 Subpart MMMM, as last revised April 26, 2004.
(2) AM I SUBJECT TO THIS SUBCHAPTER?
(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.
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 high
performance, magnet wire, rubber-to-metal or extreme performance fluoropolymer
coating operations.
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).
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).
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).
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).
(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.
(c) This subchapter does not apply to surface
coating or a coating operation that meets any of the criteria of subds. 1. to
17.
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.
Coatings used in volumes of less than 189 liters (50 gallons) per year,
provided that the total volume of coatings exempt under this paragraph does not
exceed 946 liters (250 gallons) per year at the facility.
4. The surface coating of metal 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.
5. Surface coating where
plastic is extruded onto metal wire or cable or metal parts or products to form
a coating.

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 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.
(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 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.
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.
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).
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.
