(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 4., except as
specified in par. (c), determined according to the requirements in s.
NR 465.36(2), 465.37(2) or 465.38(2).
1. For each new or reconstructed general use
coating affected source, limit organic HAP emissions to no more than 0.16 kg
(0.16 lb) of organic HAP emitted per kg (lb) of coating solids used during each
12-month compliance period.
2. For
each new or reconstructed automotive lamp coating affected source, limit
organic HAP emissions to no more than 0.26 kg (0.26 lb) of organic HAP emitted
per kg (lb) of coating solids used during each 12-month compliance
period.
3. For each new or
reconstructed thermoplastic olefin coating affected source, limit organic HAP
emissions to no more than 0.22 kg (0.22 lb) of organic HAP emitted per kg (lb)
of coating solids used during each 12-month compliance period.
4. For each new or reconstructed assembled
on-road vehicle coating affected source, limit organic HAP emissions to no more
than 1.34 kg (1.34 lb) of organic HAP emitted per kg (lb) 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 4., except as specified in par.
(c), determined according to the requirements in s.
NR 465.36(2), 465.37(2) or 465.38(2).
1. For each existing general use coating
affected source, limit organic HAP emissions to no more than 0.16 kg (0.16 lb)
of organic HAP emitted per kg (lb) of coating solids used during each 12-month
compliance period.
2. For each
existing automotive lamp coating affected source, limit organic HAP emissions
to no more than 0.45 kg (0.45 lb) of organic HAP emitted per kg (lb) of coating
solids used during each 12-month compliance period.
3. For each existing thermoplastic olefin
coating affected source, limit organic HAP emissions to no more than 0.26 kg
(0.26 lb) of organic HAP emitted per kg (lb) of coating solids used during each
12-month compliance period.
4. For
each existing assembled on-road vehicle coating affected source, limit organic
HAP emissions to no more than 1.34 kg (1.34 lb) of organic HAP emitted per kg
(lb) 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 TPO 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 emission limit for all surface coating operations constitutes compliance
with the other applicable emission limits. You shall use kilograms or pounds 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). 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 465.35(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.
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 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 465.35(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 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 kg (lb) of solids
used in coating operation, i, in the 12-month compliance period that is subject
to emission limit, i. You may estimate the mass of coating solids used from
parameters other than coating consumption and mass solids content. The use of
parameters other than coating consumption and mass solids content shall be
approved by the administrator.
n is the number of different coating operations included in
the facility-specific emission limit
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.
c. If you need to convert an emission limit
in another surface coating NESHAP from kg (lb) of organic HAP per liter
(gallon) of coating solids used to kg (lb) of organic HAP per kg (lb) of
coating solids used, you shall use the default solids density of 1.50 kg solids
per liter of coating solids (12.5 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 465.35(3)
(c), and you shall report it in the next
semiannual compliance report required in s.
NR 465.35(2).
(a)
Compliant material
option. You shall meet all the requirements of s.
NR 465.36 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 or 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 465.37 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 465.38 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 465.38(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 in sub. (2) (a) or the emission
rate without add-on controls option 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 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 465.38(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
operation or 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 465.38(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
MUST I MEET?
(a) For any coating operation or
operations on which you use the compliant material option in sub. (2) (a) or
the emission rate without add-on controls option 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 and 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 and other additives, cleaning materials, and waste materials shall be
stored in closed containers.
2.
Spills of organic-HAP-containing coatings, thinners and other additives,
cleaning materials, and waste materials shall be minimized.
3. Organic-HAP-containing coatings, thinners
and 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.
environmental protection agency may choose to grant you permission to use an
alternative to the work practice standards in this subsection.
