NR 465.28(8)(e)1.1. During the performance test, 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 465.28(8)(e)2.2. Use the data collected during the performance test to calculate and record the average temperature. This is the minimum operating limit for the desorption concentrate gas stream temperature.

NR 465.28(8)(e)3.3. During the performance test, 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 465.28(8)(e)4.4. Use the data collected during the performance test to calculate and record the average pressure drop. This is the maximum operating limit for the dilute stream across the concentrator.

NR 465.28(8)(f)2.2. For each capture device that is not part of a PTE that meets the criteria of sub. (6) (a), according to both of the following:

NR 465.28(8)(f)2.a.a. During the capture efficiency determination required by sub. (1) and described in subs. (5) and (6), 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 465.28(8)(f)2.b.b. 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 is the minimum operating limit for that specific capture device.

NR 465.28(9)(a)1.1. You shall install, operate and maintain each CPMS according to the following requirements, except that subd. 1. a. and b. do not apply to capture system bypass lines and carbon adsorbers as specified in pars. (b) and (d):

NR 465.28(9)(a)1.a.a. 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 465.28(9)(a)1.b.b. Determine the average of all recorded readings for each successive 3-hour period of the emission capture system and add-on control device operation except as specified in subd. 1. f.

NR 465.28(9)(a)1.c.c. Record the results of each inspection, calibration and validation check of the CPMS.

NR 465.28(9)(a)1.d.d. Maintain the CPMS at all times and have available necessary parts for routine repairs of the monitoring equipment.

NR 465.28(9)(a)1.e.e. 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 465.28(9)(a)1.f.f. 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 465.28(9)(a)2.2. 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. Except for periods of required quality assurance or control activities, any period during which the CPMS fails to operate and record data continuously as required by subd. 1. a., or generates data that cannot be included in calculating averages as specified in subd. 1. f., is a deviation from the monitoring requirements.

NR 465.28(9)(b)(b) Capture system bypass line. You shall comply with all of the following requirements, in addition to those specified in par. (a) 1. c. to e., for each emission capture system that contains bypass lines that could divert emissions away from the add-on control device to the atmosphere:

NR 465.28(9)(b)1.1. Monitor or secure the valve or closure mechanism controlling the bypass line in a nondiverting position in such a way that the valve or closure mechanism cannot be opened without creating a record that the valve was opened. The method used to monitor or secure the valve or closure mechanism shall meet one of the following requirements:

NR 465.28(9)(b)1.a.a. Install, calibrate, maintain and operate, according to the manufacturer’s specifications, a flow control position indicator that takes a reading at least once every 15 minutes and provides a record indicating whether the emissions are directed to the add-on control device or diverted from the add-on control device. The time of occurrence and flow control position shall be recorded, as well as every time the flow direction is changed. The flow control position indicator shall be installed at the entrance to any bypass line that could divert the emissions away from the add-on control device to the atmosphere.

NR 465.28(9)(b)1.b.b. Secure any bypass line valve in the closed position with a car-seal or a lock-and-key type configuration. You shall visually inspect the seal or closure mechanism at least once every month to ensure that the valve is maintained in the closed position and the emissions are not diverted away from the add-on control device to the atmosphere.

NR 465.28(9)(b)1.c.c. Ensure that any bypass line valve is in the closed, non-diverting, position through monitoring of valve position at least once every 15 minutes. You shall inspect the monitoring system at least once every month to verify that the monitor will indicate valve position.

NR 465.28(9)(b)1.d.d. Use an automatic shutdown system in which the coating operation is stopped when flow is diverted by the bypass line away from the add-on control device to the atmosphere when the coating operation is running. You shall inspect the automatic shutdown system at least once every month to verify that it will detect diversions of flow and shutdown the coating operation.

NR 465.28(9)(b)2.2. If any bypass line is opened, you shall include a description of why the bypass line was opened and the length of time it remained open in the semiannual compliance reports required in s. NR 465.25 (2).

NR 465.28(9)(c)(c) Thermal oxidizers and catalytic oxidizers. If you are using a thermal oxidizer or catalytic oxidizer as an add-on control device, including those used with concentrators or with carbon adsorbers to treat desorbed concentrate streams, you shall comply with the following requirements, as applicable, in addition to those specified in par. (a) 1.:

NR 465.28(9)(c)1.1. For a thermal oxidizer, install a gas temperature monitor in the firebox of the thermal oxidizer or in the duct immediately downstream of the firebox before any substantial heat exchange occurs.

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.
