You shall complete any performance test required in s. NR 466.24 (3) within the time limits specified in s. NR 460.06 (1) (b). NR 466.23(3)(c)(c) If you own or operate a reconstructed affected source subject to the provisions of this subchapter, your compliance date is immediately upon startup of the affected source or by December 4, 2002, whichever is later. Existing affected sources which have undergone reconstruction as defined in s. NR 460.02 are subject to the requirements for new affected sources. The costs associated with the purchase and installation of air pollution control equipment are not considered in determining whether the existing affected source has been reconstructed. Additionally, the costs of retrofitting and replacing equipment that is installed specifically to comply with this subchapter are not considered reconstruction costs. You shall complete any performance test required in s. NR 466.24 (3) within the time limits specified in s. NR 460.06 (1) (b). NR 466.23 HistoryHistory: CR 07-045: cr. Register April 2008 No. 628, eff. 5-1-08. NR 466.24NR 466.24 General requirements for compliance with the emission standards and for monitoring and performance tests. NR 466.24(1)(1) What general requirements must I meet to comply with the standards? You shall comply with the applicable general provisions of ch. NR 460 as specified in ch. NR 460 Appendix JJJJ. NR 466.24(2)(2) If I use a control device to comply with the emission standards, what monitoring must I do? NR 466.24(2)(b)(b) Capture system and control device monitoring. Following the date on which the initial performance test of a control device is completed to demonstrate continuing compliance with the standards, you shall monitor and inspect each capture system and each control device used to comply with s. NR 466.23 (1). You shall install and operate the monitoring equipment as specified in pars. (c) and (f). NR 466.24(2)(c)(c) Bypass and coating use monitoring. If you own or operate web coating lines with intermittently-controlled work stations, you shall monitor bypasses of the control device and the mass of each coating material applied at the work station during any bypass. If using a control device for complying with the requirements of this subchapter, you shall demonstrate that any coating material applied on a never-controlled work station or an intermittently-controlled work station operated in bypass mode is allowed in your compliance demonstration according to s. NR 466.25 (14) and (15). The bypass monitoring shall be conducted using at least one of the procedures in subds. 1. to 4. for each work station and associated dryer. NR 466.24(2)(c)1.1. ‘Flow control position indicator.’ Install, calibrate, maintain and operate according to the manufacturer’s specifications a flow control position indicator that provides a record indicating whether the exhaust stream from the dryer was directed to the control device or was diverted from the control device. The time and flow control position shall be recorded at least once per hour as well as every time the flow direction is changed. A flow control position indicator shall be installed at the entrance to any bypass line that could divert the exhaust stream away from the control device to the atmosphere. NR 466.24(2)(c)2.2. ‘Car-seal or lock-and-key valve closures.’ Secure any bypass line valve in the closed position with a car-seal or a lock-and-key type configuration. A visual inspection of the seal or closure mechanism shall be performed at least once every month to ensure that the valve or damper is maintained in the closed position, and the exhaust stream is not diverted through the bypass line. NR 466.24(2)(c)3.3. ‘Valve closure continuous monitoring.’ Ensure that any bypass line valve or damper is in the closed position through continuous monitoring of valve position when the emission source is in operation and is using a control device for compliance with the requirements of this subchapter. The monitoring system shall be inspected at least once every month to verify that the monitor will indicate valve position. NR 466.24(2)(c)4.4. ‘Automatic shutdown system.’ Use an automatic shutdown system in which the web coating line is stopped when flow is diverted away from the control device to any bypass line when the control device is in operation. The automatic system shall be inspected at least once every month to verify that it will detect diversions of flow and would shut down operations in the event of such a diversion. NR 466.24(2)(d)(d) Solvent recovery unit. If you own or operate a solvent recovery unit to comply with s. NR 466.23 (1), you shall meet the requirements in either subd. 1. or 2., depending on how control efficiency is determined. NR 466.24(2)(d)1.1. ‘Continuous emission monitoring system (CEMS).’ If you are demonstrating compliance with the emission standards in s. NR 466.23 (1) through continuous emission monitoring of a control device, you shall install, calibrate, operate and maintain the CEMS according to subd. 1. a. to c. NR 466.24(2)(d)1.a.a. 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). In conducting the quarterly audits of the monitors as required by procedure 1, Appendix F, you shall use compounds representative of the gaseous emission stream being controlled. 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.
