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.
NR 465.28(6)(b)2.d. d. For each capture efficiency test run, determine the percent capture efficiency of the emission capture system, using the following equation:
(Equation 7)
where:
  CE is the capture efficiency of the emission capture system 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

NR 465.28(9)(c)2. 2. For a catalytic oxidizer, install a gas temperature monitor in the gas stream immediately before the catalyst bed, and if you establish operating limits according to sub. (8) (b) 1. and 2., also install a gas temperature monitor in the gas stream immediately after the catalyst bed.
