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. NR 465.28(6)(a)2.2. 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. NR 465.28(6)(b)(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: NR 465.28(6)(b)1.1. ‘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: NR 465.28(6)(b)1.a.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). NR 465.28(6)(b)1.b.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. NR 465.28(6)(b)1.c.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: (Equation 5)
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
NR 465.28(6)(b)1.d.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. NR 465.28(6)(b)1.e.e. For each capture efficiency test run, determine the percent capture efficiency of the emission capture system, using the following equation: (Equation 6)
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
NR 465.28(6)(b)1.f.f. Determine the capture efficiency of the emission capture system as the average of the capture efficiencies measured in the 3 test runs. NR 465.28(6)(b)2.2. ‘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. NR 465.28(6)(b)2.a.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). NR 465.28(6)(b)2.b.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. NR 465.28(6)(b)2.c.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.
