(1) WHAT EMISSION LIMITS MUST I MEET?
(a) For a new or reconstructed affected
source, you shall limit organic HAP emissions to the atmosphere from the
affected source to the applicable limit specified in subds. 1. to 5., except as
specified in par. (c), determined according to the requirements in s.
NR 465.46(2), 465.47(2) or 465.48(2).
1. For each new or reconstructed general use
coating affected source, limit organic HAP emissions to no more than 0.23
kilograms (kg) (1.9 pounds (lb)) of organic HAP per liter (gallon) of coating
solids used during each 12-month compliance period.
2. For each new or reconstructed high
performance coating affected source, limit organic HAP emissions to no more
than 3.3 kg (27.5 lb) of organic HAP per liter (gallon) of coating solids used
during each 12-month compliance period.
3. For each new or reconstructed magnet wire
coating affected source, limit organic HAP emissions to no more than 0.050 kg
(0.44 lb) of organic HAP per liter (gallon) of coating solids used during each
12-month compliance period.
4. For
each new or reconstructed rubber-to-metal coating affected source, limit
organic HAP emissions to no more than 0.81 kg (6.8 lb) of organic HAP per liter
(gallon) of coating solids used during each 12-month compliance
period.
5. For each new or
reconstructed extreme performance fluoropolymer coating affected source, limit
organic HAP emissions to no more than 1.5 kg (12.4 lb) of organic HAP per liter
(gallon) of coating solids used during each 12-month compliance
period.
(b) For an
existing affected source, you shall limit organic HAP emissions to the
atmosphere from the affected source to the applicable limit specified in subds.
1. to 5., except as specified in par. (c), determined according to the
requirements in s.
NR 465.46(2), 465.47(2) or 465.48(2).
1. For each existing general use coating
affected source, limit organic HAP emissions to no more than 0.31 kg (2.6 lb)
of organic HAP per liter (gallon) of coating solids used during each 12-month
compliance period.
2. For each
existing high performance coating affected source, limit organic HAP emissions
to no more than 3.3 kg (27.5 lb) of organic HAP per liter (gallon) of coating
solids used during each 12-month compliance period.
3. For each existing magnet wire coating
affected source, limit organic HAP emissions to no more than 0.12 kg (1.0 lb)
of organic HAP per liter (gallon) of coating solids used during each 12-month
compliance period.
4. For each
existing rubber-to-metal coating affected source, limit organic HAP emissions
to no more than 4.5 kg (37.7 lb) of organic HAP per liter (gallon) of coating
solids used during each 12-month compliance period.
5. For each existing extreme performance
fluoropolymer coating affected source, limit organic HAP emissions to no more
than 1.5 kg (12.4 lb) of organic HAP per liter (gallon) of coating solids used
during each 12-month compliance period.
(c) If your facility's surface coating
operations meet the applicability criteria of more than one of the sub-category
emission limits specified in par. (a) or (b), you may comply separately with
each sub-category emission limit or comply using one of the alternatives in
subd. 1. or 2.
1. If the general use or
magnet wire surface coating operations subject to only one of the emission
limits specified in par. (a) 1. or 3. or (b) 1. or 3. account for 90% or more
of the surface coating activity at your facility, then compliance with that one
emission limit in this subchapter for all surface coating operations
constitutes compliance with the other applicable emission limits. 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. 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). Additionally, you shall determine the
facility's predominant activity annually and include the determination in the
next semi-annual compliance report required by s.
NR 465.45(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.
2. You may calculate and comply with a
facility-specific emission limit as described in subd. 2. a. to c. 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 pars. (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 the other sub-categories and
constitute more than one percent of total coating activities. 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.
a. You are required to
calculate the facility-specific emission limit for your facility when you
submit the notification of compliance status required in s.
NR 465.45(1)
(c), and on a monthly basis afterward using
the coating data for the relevant 12-month compliance period.
b. Use Equation 1 of this subsection to
calculate the facility-specific emission limit for your surface coating
operations for each 12-month compliance period:
See
Image
where:
Facility-specific emission limit is the facility-specific
emission limit for each 12-month compliance period, kg (lb) of organic HAP per
kg (lb) of coating solids used
Limiti is the new source or existing
source emission limit as specified in s. NR 465.43(1) applicable to coating
operation, i, included in the facility-specific emission limit, converted to kg
(lb) of organic HAP per kg (lb) of coating solids used, if the emission limit
is not already in those units. All emission limits included in the
facility-specific emission limit shall be in the same units.
Solidsi is the liters (gallons) of
solids used in coating operation, i, in the 12-month compliance period that is
subject to emission limit, i, as specified in s. NR 465.43(1). You may estimate
the 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 use of
parameters other than coating consumption and volume solids content shall be
approved by the administrator.
n is the number of different coating operations included in
the facility-specific emission limit
c. If you need to convert an emission limit
in another surface coating NESHAP from kg (lb) of organic HAP per kg (lb) of
coating solids used to kg (lb) of organic HAP per liter (gallon) of coating
solids used, you shall use the default solids density of 1.26 kg of solids per
liter of coating solids (10.5 lb of solids per gallon of coating
solids).
(2) WHAT ARE MY OPTIONS FOR MEETING THE
EMISSION LIMITS? You shall include all coatings, thinners and other additives,
and cleaning materials used in the affected source when determining whether the
organic HAP emission rate is equal to or less than the applicable emission
limit in sub. (1). To make this determination, you shall use at least one of
the 3 compliance options listed in pars. (a) to (c). You may apply any of the
compliance options to an individual coating operation, or to multiple coating
operations as a group, or to the entire affected source. You may use different
compliance options for different coating operations, or at different times on
the same coating operation. You may employ different compliance options when
different coatings are applied to the same part, or when the same coating is
applied to different parts. However, you may not use different compliance
options at the same time on the same coating operation. If you switch between
compliance options for any coating operation or group of coating operations,
you shall document this switch as required by s.
NR 465.45(3)
(c), and you shall report it in the next
semiannual compliance report required in s.
NR 465.45(2).
(a)
Compliant material
option. You shall meet all the requirements of s.
NR 465.46 to demonstrate compliance with the applicable
emission limit in sub. (1) using this option. To use this option, you shall
demonstrate that the organic HAP content of each coating used in the coating
operation or operations is less than or equal to the applicable emission limit
in sub. (1), and that each thinner and other additive, and cleaning material
used contains no organic HAP.
(b)
Emission rate without add-on controls option. You shall meet
all the requirements of s.
NR 465.47 to demonstrate compliance with the emission
limit in sub. (1) using this option. To use this option, you shall demonstrate
that, based on the coatings, thinners and other additives, and cleaning
materials used in the coating operation or operations, the organic HAP emission
rate for the coating operation or operations is less than or equal to the
applicable emission limit in sub. (1), calculated as a rolling 12-month
emission rate and determined on a monthly basis.
(c)
Emission rate with add-on
controls option. You shall meet all the requirements of s.
NR 465.48 to demonstrate compliance with the emission
limits in sub. (1), the operating limits in sub. (3) and the work practice
standards in sub. (4) using this option. To use this option, you shall
demonstrate that, based on the coatings, thinners and other additives, and
cleaning materials used in the coating operation or operations, and the
emissions reductions achieved by emission capture systems and add-on controls,
the organic HAP emission rate for the coating operation or operations is less
than or equal to the applicable emission limit in sub. (1), calculated as a
rolling 12-month emission rate and determined on a monthly basis. If you use
this compliance option, you shall also demonstrate that all emission capture
systems and add-on control devices for the coating operation or operations meet
the operating limits required in sub. (3), except for solvent recovery systems
for which you conduct liquid-liquid material balances according to s.
NR 465.48(2) (j), and that you meet the
work practice standards required in sub. (4).
(3) WHAT OPERATING LIMITS MUST I MEET?
(a) For any coating operation or operations
on which you use the compliant material option specified in sub. (2) (a) or the
emission rate without add-on controls option specified in sub. (2) (b), you are
not required to meet any operating limits.
(b) For any controlled coating operation or
operations on which you use the emission rate with add-on controls option
specified in sub. (2) (c), except those for which you use a solvent recovery
system and conduct a liquid-liquid material balance according to s.
NR 465.48(2) (j), you shall meet the
operating limits specified in Table 1 of this subchapter. These operating
limits apply to the emission capture and control systems on the coating
operations for which you use this option, and you shall establish the operating
limits during the performance test according to the requirements in s.
NR 465.48(8). You shall meet the
operating limits at all times after you establish them.
(c) If you use an add-on control device other
than those listed in Table 1 of this subchapter, or wish to monitor an
alternative parameter and comply with a different operating limit, you shall
apply to the administrator for approval of alternative monitoring under
40 CFR
63.8(f).
(4) WHAT WORK PRACTICE STANDARDS
SHALL I MEET?
(a) For any coating operation
or operations on which you use the compliant material option specified in sub.
(2) (a) or the emission rate without add-on controls option specified in sub.
(2) (b), you are not required to meet any work practice standards.
(b) If you use the emission rate with add-on
controls option in sub. (2) (c), you shall develop and implement a work
practice plan to minimize organic HAP emissions from the storage, mixing and
conveying of coatings, thinners, other additives and cleaning materials used
in, and waste materials generated by the controlled coating operations for
which you use this option; or you shall meet an alternative standard as
provided in par. (c). The plan shall specify practices and procedures to ensure
that, at a minimum, the elements specified in subds. 1. to 5. are implemented.
1. All organic-HAP-containing coatings,
thinners, other additives, cleaning materials and waste materials shall be
stored in closed containers.
2.
Spills of organic-HAP-containing coatings, thinners, other additives, cleaning
materials and waste materials shall be minimized.
3. Organic-HAP-containing coatings, thinners,
other additives, cleaning materials and waste materials shall be conveyed from
one location to another in closed containers or pipes.
4. Mixing vessels which contain
organic-HAP-containing coatings and other materials shall be closed except when
adding to, removing or mixing the contents.
5. Emissions of organic HAP shall be
minimized during cleaning of storage, mixing and conveying equipment.
(c) As provided in
40 CFR
63.6(g), the U. S. EPA may
choose to grant you permission to use an alternative to the work practice
standards in this subsection.
