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. NR 465.28(9)(c)3.3. For each gas temperature monitoring device, comply with all of the following requirements: NR 465.28(9)(c)3.a.a. Locate the temperature sensor in a position that provides a representative temperature. NR 465.28(9)(c)3.b.b. Use a temperature sensor with a measurement sensitivity of 4°F or 0.75% of the temperature value, whichever is larger. NR 465.28(9)(c)3.c.c. Shield the temperature sensor system from electromagnetic interference and chemical contaminants. NR 465.28(9)(c)3.d.d. If a gas temperature chart recorder is used, ensure that it has a measurement sensitivity in the minor division of at least 20°F. NR 465.28(9)(c)3.e.e. Perform an electronic calibration at least semiannually according to the procedures in the manufacturer’s owners manual. Following the electronic calibration, conduct a temperature sensor validation check in which a second or redundant temperature sensor placed nearby the process temperature sensor yields a reading within 30°F of the process temperature sensor’s reading. NR 465.28(9)(c)3.f.f. Any time the sensor exceeds the manufacturer’s specified maximum operating temperature range, either conduct calibration and validation checks or install a new temperature sensor. NR 465.28(9)(c)3.g.g. At least monthly, inspect components for integrity and electrical connections for continuity, oxidation and galvanic corrosion. NR 465.28(9)(d)(d) Carbon adsorbers. If you are using a carbon adsorber as an add-on control device, you shall monitor the total regeneration desorbing gas (e. g., steam or nitrogen) mass flow for each regeneration cycle and the carbon bed temperature after each regeneration and cooling cycle and comply with all of the following requirements, in addition to those specified in par. (a) 1. c. to e.: NR 465.28(9)(d)1.1. The regeneration desorbing gas mass flow monitor shall be an integrating device having a measurement sensitivity of ±10%, capable of recording the total regeneration desorbing gas mass flow for each regeneration cycle. NR 465.28(9)(d)2.2. The carbon bed temperature monitor shall have a measurement sensitivity of 1% of the temperature recorded or 1°F, whichever is greater, and shall be capable of recording the temperature within 15 minutes of completion of any carbon bed cooling cycle. NR 465.28(9)(e)(e) Condensers. If you are using a condenser, you shall monitor the condenser outlet (product side) gas temperature and comply with all of the following requirements in addition to those specified in par. (a) 1.: NR 465.28(9)(e)1.1. The gas temperature monitor shall have a measurement sensitivity of 1% of the temperature recorded or 1°F, whichever is greater. NR 465.28(9)(e)2.2. The temperature monitor shall provide a gas temperature record at least once every 15 minutes. NR 465.28(9)(f)(f) Concentrators. If you are using a concentrator, such as a zeolite wheel or rotary carbon bed concentrator, you shall comply with all of the following requirements, in addition to those specified in par. (a) 1.: NR 465.28(9)(f)2.2. Install a device to monitor pressure drop across the zeolite wheel or rotary carbon bed and meet all of the following requirements: NR 465.28(9)(f)2.a.a.
