Measure the total organic volatile matter mass flow rate at both the control device inlet and the outlet such that the reduction efficiency can be determined. Each continuous emission monitor shall comply with performance specification 6, 8 or 9, as appropriate, of 40 CFR part 60, Appendix B, incorporated by reference in s. NR 484.04 (21). NR 466.24(2)(d)1.b.b. You shall follow the quality assurance procedures in procedure 1, of 40 CFR part 60, Appendix F, incorporated by reference in s. NR 484.04 (21m).

NR 466.24(2)(d)1.c.c. You shall have valid data from at least 90% of the hours during which the process is operated. NR 466.24(2)(d)2.2. ‘Liquid-liquid material balance.’ If you are demonstrating compliance with the emission standards in s. NR 466.23 (1) through liquid-liquid material balance, you shall install, calibrate, maintain and operate according to the manufacturer’s specifications a device that indicates the cumulative amount of volatile matter recovered by the solvent recovery device on a monthly basis. The device shall be certified by the manufacturer to be accurate to within ±2.0% by mass. NR 466.24(2)(e)(e) Continuous parameter monitoring system (CPMS). If you are using a control device to comply with the emission standards in s. NR 466.23 (1), you shall install, operate and maintain each CPMS specified in subds. 9. and 10. and par. (f) according to the requirements in subds. 1. to 8. You shall install, operate and maintain each CPMS specified in par. (c) according to subds. 5. to 7. NR 466.24(2)(e)1.1. Each 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 to have a valid hour of data. NR 466.24(2)(e)2.2. You shall have valid data from at least 90% of the hours during which the process operated. NR 466.24(2)(e)3.a.a. To calculate a valid hourly value, you shall have at least 3 of 4 equally spaced data values from that hour from a continuous monitoring system (CMS) that is not out-of-control. NR 466.24(2)(e)3.b.b. Provided all of the readings recorded in accordance with this subdivision clearly demonstrate continuous compliance with the standard that applies to you, then you are not required to determine the hourly average of all recorded readings. NR 466.24(2)(e)4.4. You shall determine the rolling 3-hour average of all recorded readings for each operating period. To calculate the average for each 3-hour averaging period, you shall have at least 2 of 3 of the hourly averages for that period using only average values that are based on valid data not from out-of-control periods. NR 466.24(2)(e)5.5. You shall record the results of each inspection, calibration and validation check of the CPMS. NR 466.24(2)(e)6.6. At all times, you shall maintain the monitoring system in proper working order, including maintaining necessary parts for routine repairs of the monitoring equipment. NR 466.24(2)(e)7.7. Except for monitoring malfunctions, associated repairs or required quality assurance or control activities, including calibration checks or required zero and span adjustments, you shall conduct all monitoring at all times that the unit is operating. Data recorded during monitoring malfunctions, associated repairs, out-of-control periods or required quality assurance or control activities may not be used for purposes of calculating the emissions concentrations and percent reductions specified in s. NR 466.25 (1). You shall use all the valid data collected during all other periods in assessing compliance of the control device and associated control system. A monitoring malfunction is any sudden, infrequent, not reasonably preventable failure of the monitoring system to provide valid data. Monitoring failures that are caused in part by poor maintenance or careless operation are not malfunctions. NR 466.24(2)(e)8.8. Any averaging period for which you do not have valid monitoring data, and the data are required, constitutes a deviation, and you shall notify the department in accordance with s. NR 466.26 (1) (c). NR 466.24(2)(e)9.9. If you are using an oxidizer to comply with the emission standards, you shall comply with subd. 9. a. to c. NR 466.24(2)(e)9.a.a. Install, calibrate, maintain and operate temperature monitoring equipment according to the manufacturer’s specifications. The calibration of the chart recorder, data logger or temperature indicator shall be verified every 3 months or the chart recorder, data logger or temperature indicator shall be replaced. You shall replace the equipment whether you choose not to perform the calibration or the equipment cannot be calibrated properly. NR 466.24(2)(e)9.b.b. For an oxidizer other than a catalytic oxidizer, install, calibrate, operate and maintain a temperature monitoring device equipped with a continuous recorder. The device shall have an accuracy of ±1% of the temperature being monitored in degrees Celsius, or ±1° Celsius, whichever is greater. The thermocouple or temperature sensor shall be installed in the combustion chamber at a location in the combustion zone. NR 466.24(2)(e)9.c.c. For a catalytic oxidizer, install, calibrate, operate and maintain a temperature monitoring device equipped with a continuous recorder. The device shall be capable of monitoring temperature with an accuracy of ±1% of the temperature being monitored in degrees Celsius or ±1° Celsius, whichever is greater. The thermocouple or temperature sensor shall be installed in the vent stream at the nearest feasible point to the inlet and outlet of the catalyst bed. Calculate the temperature rise across the catalyst. NR 466.24(2)(e)10.10. If you use a control device other than an oxidizer or wish to monitor an alternative parameter and comply with a different operating limit, you shall apply to the department for approval of an alternative monitoring method under s. NR 460.07 (6). NR 466.24(2)(f)(f) Capture system monitoring. If you are complying with the emission standards in s. NR 466.23 (1) through the use of a capture system and control device for one or more web coating lines, you shall develop a site-specific monitoring plan containing the information specified in subds. 1. and 2. for the capture systems. You shall monitor the capture system in accordance with subd. 3. You shall make the monitoring plan available for inspection by the department upon request. NR 466.24(2)(f)1.a.a. Identify the operating parameter to be monitored to ensure that the capture efficiency determined during the initial compliance test is maintained. NR 466.24(2)(f)1.b.b. Explain why the operating parameter is appropriate for demonstrating ongoing compliance. NR 466.24(2)(f)2.2. The monitoring plan shall specify the operating parameter value or range of values that demonstrate compliance with the emission standards in s. NR 466.23 (1). The specified operating parameter value or range of values shall represent the conditions present when the capture system is being properly operated and maintained. NR 466.24(2)(f)3.3. You shall conduct all capture system monitoring in accordance with the plan. NR 466.24(2)(f)4.4. Any deviation from the operating parameter value or range of values which are monitored according to the plan will be considered a deviation from the operating limit.
