NR 465.48(8)(b)3.3. You shall monitor the temperature at the inlet to the catalyst bed and implement a site-specific inspection and maintenance plan for your catalytic oxidizer as specified in subd. 4. During the performance test, you shall monitor and record the temperature just before the catalyst bed at least once every 15 minutes during each of the 3 test runs. Use the data collected during the performance test to calculate and record the average temperature just before the catalyst bed during the performance test. This average temperature shall be the minimum operating limit for your catalytic oxidizer.

NR 465.48(8)(b)4.4. You shall develop and implement an inspection and maintenance plan for your catalytic oxidizers for which you elect to monitor according to subd. 3. The plan shall address, at a minimum, the elements specified in subd. 4. a. to c.

NR 465.48(8)(b)4.a.a. Annual sampling and analysis of the catalyst activity, or conversion efficiency, following the manufacturer’s or catalyst supplier’s recommended procedures. If problems are found during the catalyst activity test, you shall replace the catalyst bed or take other corrective action consistent with the manufacturer’s recommendations.

NR 465.48(8)(b)4.b.b. Monthly external inspection of the catalytic oxidizer system, including the burner assembly and fuel supply lines for problems and, as necessary, adjustment of the equipment to assure proper air-to-fuel mixtures.

NR 465.48(8)(b)4.c.c. Annual internal inspection of the catalyst bed to check for channeling, abrasion and settling. If problems are found during the annual internal inspection of the catalyst, you shall replace the catalyst bed or take other corrective action consistent with the manufacturer’s recommendations. If the catalyst bed is replaced and is not of like or better kind and quality as the old catalyst, then you shall conduct a new performance test to determine destruction efficiency according to sub. (7). If a catalyst bed is replaced and the replacement catalyst is of like or better kind and quality as the old catalyst, then a new performance test to determine destruction efficiency is not required and you may continue to use the previously established operating limits for that catalytic oxidizer.

NR 465.48(8)(c)(c) Regenerative carbon adsorbers. If your add-on control device is a regenerative carbon adsorber, establish the operating limits according to subds. 1. and 2.

NR 465.48(8)(c)1.1. You shall monitor and record the total regeneration desorbing gas mass flow for each regeneration cycle, and the carbon bed temperature after each carbon bed regeneration and cooling cycle for the regeneration cycle either immediately preceding or immediately following the performance test.

NR 465.48(8)(c)2.2. The operating limits for your regenerative carbon adsorber shall be the minimum total desorbing gas mass flow recorded during the regeneration cycle and the maximum carbon bed temperature recorded after the cooling cycle.

NR 465.48(8)(d)1.1. During the performance test, you shall monitor and record the condenser outlet, or product side, gas temperature at least once every 15 minutes during each of the 3 test runs.

NR 465.48(8)(d)2.2. Use the data collected during the performance test to calculate and record the average condenser outlet, or product side, gas temperature maintained during the performance test. This average condenser outlet gas temperature shall be the maximum operating limit for your condenser.

NR 465.48(8)(e)(e) Concentrators. If your add-on control device includes a concentrator, you shall establish operating limits for the concentrator according to subds. 1. to 4.

NR 465.48(8)(e)1.1. During the performance test, you shall monitor and record the desorption concentrate stream gas temperature at least once every 15 minutes during each of the 3 runs of the performance test.

NR 465.48(8)(e)2.2. Use the data collected during the performance test to calculate and record the average temperature. This average temperature shall be the minimum operating limit for the desorption concentrate gas stream temperature.

NR 465.48(8)(e)3.3. During the performance test, you shall monitor and record the pressure drop of the dilute stream across the concentrator at least once every 15 minutes during each of the 3 runs of the performance test.

NR 465.48(8)(e)4.4. Use the data collected during the performance test to calculate and record the average pressure drop. This average pressure drop shall be the minimum operating limit for the dilute stream across the concentrator.

NR 465.48(8)(f)(f) Emission capture systems. For each capture device that is not part of a PTE that meets the criteria of sub. (6) (a), establish an operating limit for either the gas volumetric flow rate or duct static pressure, as specified in subds. 1. and 2. The operating limit for a PTE is specified in Table 1 of this subchapter. If the source is a magnet wire coating machine, you may use the procedures in section 2.0 of 40 CFR part 63, Subpart MMMM, Appendix A, incorporated by reference in s. NR 484.04 (24g), as an alternative.

NR 465.48(8)(f)1.1. During the capture efficiency determination required by sub. (1) and described in subs. (5) and (6), you shall monitor and record either the gas volumetric flow rate or the duct static pressure for each separate capture device in your emission capture system at least once every 15 minutes during each of the 3 test runs at a point in the duct between the capture device and the add-on control device inlet.

NR 465.48(8)(f)2.2. Calculate and record the average gas volumetric flow rate or duct static pressure for the 3 test runs for each capture device. This average gas volumetric flow rate or duct static pressure shall be the minimum operating limit for that specific capture device.

NR 465.48(9)(a)(a) General. You shall install, operate and maintain each CPMS specified in pars. (c), (e), (f) and (g) according to subds. 1. to 6. You shall install, operate and maintain each CPMS specified in pars. (b) and (d) according to subds. 3. to 5.

NR 465.48(9)(a)1.1. The CPMS shall complete a minimum of one cycle of operation for each successive 15-minute period. You shall have a minimum of 4 equally spaced successive cycles of CPMS operation in one hour.

NR 465.48(9)(a)2.2. You shall determine the average of all recorded readings for each successive 3-hour period of the emission capture system and add-on control device operation.

NR 465.48(9)(a)5.5. You shall operate the CPMS and collect emission capture system and add-on control device parameter data at all times that a controlled coating operation is operating, except during monitoring malfunctions, associated repairs and required quality assurance or control activities, including, if applicable, calibration checks and required zero and span adjustments.

NR 465.48(9)(a)6.6. You may not use emission capture system or add-on control device parameter data recorded during monitoring malfunctions, associated repairs, out-of-control periods, or required quality assurance or control activities when calculating data averages. You shall use all the data collected during all other periods in calculating the data averages for determining compliance with the emission capture system and add-on control device operating limits.

NR 465.48(9)(a)7.7. A monitoring malfunction is any sudden, infrequent, not reasonably preventable failure of the CPMS to provide valid data. Monitoring failures that are caused in part by poor maintenance or careless operation are not malfunctions. Any period for which the monitoring system is out-of-control and data are not available for required calculations is a deviation from the monitoring requirements.

NR 465.48(9)(b)(b) Capture system bypass line. You shall meet the requirements of subds. 1. and 2. for each emission capture system that contains bypass lines that could divert emissions away from the add-on control device to the atmosphere.
