This requirement does not apply to solvent recovery systems for which you conduct liquid-liquid material balances according to sub. (2) (g).

(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.

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 equations:

If an operating parameter deviates from the operating limit specified in Table 1 of this subchapter, assume that the emission capture system and add-on control device were achieving zero efficiency during the time period of the deviation. For the purposes of completing the compliance calculations specified in sub.

You may not include those materials in the calculation of organic HAP emissions reductions in Equation 1 in sub. (2) (f).

(d) You shall meet the requirements for bypass lines in sub. (9) (b). You shall report it as a deviation, as specified in s.

NR 460.05(4) and 460.06(4) (a), deviations that occur during a period of startup, shutdown or malfunction of the emission capture system, add-on control device or coating operation that may affect emission capture or control device efficiency are not violations if you demonstrate to the department's satisfaction that you were operating in accordance with the SSMP. The department will determine whether deviations that occur during a period of startup, shutdown or malfunction are violations according to the provisions in s. NR 460.05(4).

(j) You shall maintain records as specified in s. NR 465.25(3) and (4).

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 representative inlet concentration. You shall record information that is necessary to document emission capture system and add-on control device 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:

TVH_used 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

TVH_i 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

Vol_i is the total volume of coating, thinner or cleaning material, i, used in the coating operation during the capture efficiency test run, liters

D_i 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

TVH_used 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 control device without a single common duct, the emissions entering the add-on control device shall be simultaneously measured in each duct, and the total emissions entering the add-on control device shall be determined.

c. 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 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:

CE is the capture efficiency of the emission capture system vented to the add-on control device, percent

TVH_captured 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

TVH_uncaptured 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 capture efficiencies measured in the 3 test runs.

3. 'Alternative capture efficiency protocol.' As an alternative to the procedures specified in subds. 1. and 2., you may determine capture efficiency using any other capture efficiency protocol and test methods that satisfy the criteria of either the DQO or LCL approach as described in 40 CFR part 63, Subpart KK, Appendix A, incorporated by reference in s. NR 484.04(24).

(7) HOW DO I DETERMINE THE ADD-ON CONTROL DEVICE EMISSION DESTRUCTION OR REMOVAL EFFICIENCY?.

(a) For all types of add-on control devices, use the following test methods:
