(2) HOW DO I DEMONSTRATE INITIAL COMPLIANCE?.
You may use the emission rate with add-on controls option for any coating
operation, for any group of coating operations in the affected source or for
all of the coating operations in the affected source. You may include both
controlled and uncontrolled coating operations in a group for which you use
this option. You shall use either the compliant material option or the emission
rate without add-on controls option for any coating operation or operations in
the affected source for which you do not use this option. To demonstrate
initial compliance, the coating operation or operations for which you use the
emission rate with add-on controls option shall meet the applicable emission
limit in s.
NR 465.23(1) and the work practice
standards required in s.
NR 465.23(4), and each controlled
coating operation shall meet the operating limits required in s.
NR 465.23(3). When calculating the
organic HAP emission rate according to this subsection, do not include any
coatings, thinners or cleaning materials used on coating operations for which
you use the compliant material option or the emission rate without add-on
controls option. You do not need to redetermine the mass of organic HAP in
coatings, thinners or cleaning materials that have been reclaimed onsite and
reused in the coating operation or operations for which you use the emission
rate with add-on controls option. You shall meet all of the following
requirements to demonstrate initial compliance with the emission limitations:
(a) Except as provided in sub. (1) (b) 4. and
except for solvent recovery systems for which you conduct liquid-liquid
material balances according to the requirements of par. (g), establish and
demonstrate continuous compliance during the initial compliance period with the
operating limits required by s.
NR 465.23(3), using the procedures
specified in subs. (8) and (9).
(b)
Develop, implement and document your implementation of the work practice plan
required by s.
NR 465.23(4) during the initial
compliance period as specified in s.
NR 465.25(3).
(c) Follow the procedures specified in s.
NR 465.27(2) (a) to (d), to determine
the mass fraction of organic HAP, density and volume of each coating, thinner
and cleaning material used during the compliance period, and the volume
fraction of coating solids for each coating used during the compliance
period.
(d) Using Equation 1 in s.
NR 465.27(2), calculate the total mass
of organic HAP emissions before add-on controls from all coatings, thinners and
cleaning materials used during the compliance period in the coating operation
or group of coating operations for which you use the emission rate with add-on
controls option.
(e) Determine the
mass of organic HAP emissions reduced for each controlled coating operation
during the compliance period. The emissions reduction determination quantifies
the total organic HAP emissions that pass through the emission capture system
and are destroyed or removed by the add-on control device. Use the procedures
in par. (f) to calculate the mass of organic HAP emissions reduction for each
controlled coating operation using an emission capture system and add-on
control device other than a solvent recovery system for which you conduct
liquid-liquid material balances. For each controlled coating operation using a
solvent recovery system for which you conduct a liquid-liquid material balance,
use the procedures in par. (g) to calculate the organic HAP emissions
reduction.
(f) For each controlled
coating operation using an emission capture system and add-on control device
other than a solvent recovery system for which you conduct liquid-liquid
material balances, calculate the organic HAP emissions reduction by applying
the emission capture system efficiency and add-on control device efficiency to
the mass of organic HAP contained in the coatings, thinners and cleaning
materials that are used in the coating operation served by the emission capture
system and add-on control device during the compliance period. For any period
of time a deviation specified in sub. (4) (c) or (d) occurs in the controlled
coating operation, including a deviation during a period of startup, shutdown
or malfunction, you shall assume zero efficiency for the emission capture
system and add-on control device. For the purposes of completing the compliance
calculations, you shall treat the materials used during a deviation on a
controlled coating operation as if they were used on an uncontrolled coating
operation for the time period of the deviation. You may not include those
materials in the calculations of organic HAP emissions reduction in Equation 1.
The organic HAP emissions reduction shall be calculated using the following

(b) 6. and (2) (g).
(c) You shall demonstrate continuous

(a) and under the following conditions unless
you obtain a waiver of the performance test according to the provisions in s.
NR 460.06(7):
1. Representative operating conditions for
the coating operation. Operations during periods of startup, shutdown or
malfunction and periods of nonoperation do not constitute representative
conditions. You shall record the process information that is necessary to
document operating conditions during the test and explain why the conditions
represent normal operation.
2. When
the emission capture system and add-on control device are operating at a
representative flow rate, and the add-on control device is operating at a

operating conditions during the test and explain why the conditions represent
normal operation.
(b)
You shall conduct each performance test of an emission capture system according
to the requirements in sub. (6) and of an add-on control device according to
the requirements in sub. (7).
(c)
The performance test to determine add-on control device organic HAP destruction
or removal efficiency shall consist of 3 runs as specified in s.
NR 460.06(4)
(c) and each run shall last at least one
hour.
(6) HOW DO I
DETERMINE THE EMISSION CAPTURE SYSTEM EFFICIENCY?. You shall use the following
procedures and test methods to determine capture efficiency as part of the
performance test required by sub. (1):
(a)
You may assume the capture system efficiency is 100% if both of the following
conditions are met:
1. The capture system
meets the criteria of Method 204 in 40 CFR part 51, Appendix M, incorporated by
reference in s.
NR 484.04(9), for a PTE and directs all
the exhaust gases from the enclosure to an add-on control device.
2. All coatings, thinners and cleaning
materials used in the coating operation are applied within the capture system;
coating solvent flash-off and coating, curing and drying occurs within the
capture system; and the removal or evaporation of cleaning materials from the
surfaces they are applied to occurs within the capture system. For example,
this criterion is not met if parts enter the open shop environment when being
moved between a spray booth and a curing oven.
(b) If the capture system does not meet both
of the criteria in par. (a), use one of the 3 protocols described in subds. 1.
to 3. to measure capture efficiency. The capture efficiency measurements use
TVH capture efficiency as a surrogate for organic HAP capture efficiency. For
the protocols in subds. 1. and 2., the capture efficiency measurement shall
consist of 3 test runs. Each test run shall be at least 3 hours duration or the
length of a production run, whichever is longer, up to 8 hours. For the
purposes of this test, a production run means the time required for a single
part to go from the beginning to the end of production which includes surface
preparation activities and drying or curing time. The protocols are as follows:
1. `Liquid-to-uncaptured-gas protocol using a
temporary total enclosure or building enclosure.' The liquid-to-uncaptured-gas
protocol compares the mass of liquid TVH in materials used in the coating
operation to the mass of TVH emissions not captured by the emission capture
system. You shall use the following procedures to measure emission capture
system efficiency using the liquid-to-uncaptured-gas protocol:
a. Either use a building enclosure or
construct an enclosure around the coating operation where coatings, thinners
and cleaning materials are applied, and all areas where emissions from these
applied coatings and materials subsequently occur, such as flash-off, curing
and drying areas. The areas of the coating operation where capture devices
collect emissions for routing to an add-on control device, such as the entrance
and exit areas of an oven or spray booth, shall also be inside the enclosure.
The enclosure shall meet the applicable definition of a temporary total
enclosure or building enclosure in Method 204 in 40 CFR part 51, Appendix M,
incorporated by reference in s.
NR 484.04(9).
b. Use Method 204A or 204F in 40 CFR part 51,
Appendix M, incorporated by reference in s.
NR 484.04(9), to determine the mass
fraction of TVH liquid input from each coating, thinner and cleaning material
used in the coating operation during each capture efficiency test run. To make
the determination, substitute TVH for each occurrence of the term VOC in the
methods.
c. Use the following
equation to calculate the total mass of TVH liquid input from all the coatings,
thinners and cleaning materials used in the coating operation during each
capture efficiency test run:
See
Image
where:
TVHused is the total mass of TVH
liquid input from all coatings, thinners and cleaning materials used in the
coating operation during the capture efficiency test run, kg
TVHi is the mass fraction of TVH in
coating, thinner or cleaning material, i, that is used in the coating operation
during the capture efficiency test run, kg TVH per kg material
Voli is the total volume of coating,
thinner or cleaning material, i, used in the coating operation during the
capture efficiency test run, liters
Di is the density of coating,
thinner or cleaning material, i, kg material per liter material
n is the number of different coatings, thinners and
cleaning materials used in the coating operation during the capture efficiency
test run
d. Use Method 204D
or 204E in 40 CFR part 51, Appendix M, incorporated by reference in s.
NR 484.04(9), to measure the total mass,
kg, of TVH emissions that are not captured by the emission capture system; they
are measured as they exit the temporary total enclosure or building enclosure
during each capture efficiency test run. To make the measurement substitute TVH
for each occurrence of the term VOC in the methods. Use Method 204D if the
enclosure is a temporary total enclosure. Use Method 204E if the enclosure is a
building enclosure. During the capture efficiency measurement, all organic
compound emitting operations inside a building enclosure, other than the
coating operation for which capture efficiency is being determined, shall be
shut down, but all fans and blowers shall be operating normally.
e. For each capture efficiency test run,
determine the percent capture efficiency of the emission capture system, using
the following equation:
See
Image
where:
CE is the capture efficiency of the emission capture system
vented to the add-on control device, percent
TVHused is the total mass of TVH
liquid input used in the coating operation during the capture efficiency test
run, kg
TVHuncaptured is the total mass of TVH that is not captured
by the emission capture system and that exits from the temporary total
enclosure or building enclosure during the capture efficiency test run,
kg
f. Determine the capture
efficiency of the emission capture system as the average of the capture
efficiencies measured in the 3 test runs.
2. 'Gas-to-gas protocol using a temporary
total enclosure or a building enclosure.' The gas-to-gas protocol compares the
mass of TVH emissions captured by the emission capture system to the mass of
TVH emissions not captured. You shall use the following procedures to measure
emission capture system efficiency using the gas-to-gas protocol.
a. Either use a building enclosure or
construct an enclosure around the coating operation where coatings, thinners
and cleaning materials are applied and all areas where emissions from these
applied coatings and materials subsequently occur such as flash-off, curing and
drying areas. The areas of the coating operation where capture devices collect
emissions generated by the coating operation for routing to an add-on control
device, such as the entrance and exit areas of an oven or a spray booth, shall
also be inside the enclosure. The enclosure shall meet the applicable
definition of a temporary total enclosure or building enclosure in Method 204
in 40 CFR part 51, Appendix M, incorporated by reference in s.
NR 484.04(9).
b. Use Method 204B or 204C in 40 CFR part 51,
Appendix M, incorporated by reference in s.
NR 484.04(9), to measure the total mass,
kg, of TVH emissions captured by the emission capture system during each
capture efficiency test run as measured at the inlet to the add-on control
device. To make the measurement, substitute TVH for each occurrence of the term
VOC in the methods. The sampling points for the Method 204B or 204C measurement
shall be upstream from the add-on control device and shall represent total
emissions routed from the capture system and entering the add-on control
device. If multiple emission streams from the capture system enter the add-on

emissions entering the add-on control device shall be determined.
c. Use Method 204D or 204E in 40 CFR part 51,

NR 484.04(9), to measure the total mass,
kg, of TVH emissions that are not captured by the emission capture system; they
are measured as they exit the temporary total enclosure or building enclosure
during each capture efficiency test run. To make the measurement, substitute
TVH for each occurrence of the term VOC in the methods. Use Method 204D if the
enclosure is a temporary total enclosure. Use Method 204E if the enclosure is a
building enclosure. During the capture efficiency measurement, all organic
compound emitting operations inside the building enclosure other than the
coating operation for which capture efficiency is being determined shall be
shut down, but all fans and blowers shall be operating normally.
d. For each capture efficiency test run,
determine the percent capture efficiency of the emission capture system, using
the following equation:
See
Image
where:

vented to the add-on control device, percent
TVHcaptured is the total mass of TVH
captured by the emission capture system as measured at the inlet to the add-on
control device during the emission capture efficiency test run, kg
TVHuncaptured is the total mass of
TVH that is not captured by the emission capture system and that exits from the
temporary total enclosure or building enclosure during the capture efficiency
test run, kg
e. Determine
the capture efficiency of the emission capture system as the average of the

described in 40 CFR part 63, Subpart KK, Appendix A, incorporated by reference
in s.
NR 484.04(24).

1A in 40 CFR part 60, Appendix A, incorporated by reference in s.
NR 484.04(13), as appropriate, to select
sampling sites and velocity traverse points.

total gaseous organic mass flow rate using Equation 8 in this paragraph for
each inlet and each outlet and then total all of the inlet emissions and total
all of the outlet emissions.
