NR 466.09(4)(a)6.a.a. An exhaust gas organic volatile matter concentration of 50 parts per million by volume (ppmv) or less is required to comply with the standards of s. NR 466.06 or 466.07.

NR 466.09(4)(a)6.b.b. The organic volatile matter concentration at the inlet to the control system and the required level of control are such to result in exhaust gas organic volatile matter concentrations of 50 ppmv or less.

NR 466.09(4)(a)6.c.c. Because of the high efficiency of the control device, the anticipated organic volatile matter concentration at the control device exhaust is 50 ppmv or less, regardless of inlet concentration.

NR 466.09(4)(a)7.7. Each performance test shall consist of 3 separate runs; each run conducted for at least one hour under the conditions that exist when the affected source is operating under normal representative operating conditions. Operations during periods of startup, shutdown and malfunction do not constitute representative conditions for the purpose of a performance test. For the purpose of determining organic volatile matter concentrations and mass flow rates, the average of results of all runs shall apply.

NR 466.09(4)(b)(b) The owner or operator shall record the process information necessary to determine the conditions of the performance test.

NR 466.09(4)(c)(c) For the purpose of determining the value of the oxidizer operating parameter that will demonstrate continuing compliance, the time-weighted average of the values recorded during the performance test shall be computed. For an oxidizer other than catalytic oxidizer, the owner or operator shall establish as the operating parameter the minimum combustion temperature. For a catalytic oxidizer, the owner or operator shall establish as the operating parameter the minimum gas temperature at the inlet to the catalyst bed. These minimum temperatures are the operating parameter values that demonstrate continuing compliance with the requirements of ss. NR 466.06 and 466.07.

NR 466.09(5)(5) Capture efficiency. Except as provided for in sub. (6), a performance test to determine the capture efficiency of each capture system venting organic emissions to a control device for the purpose of meeting the requirements of ss. NR 466.06 (4) (a) 2. and (b) and 466.07 (4) (a) 2., (5) (a), (7) (b) to (d) and (9) (b) and (c) shall be conducted by the owner or operator in accordance with the following procedures:

NR 466.09(5)(a)(a) For permanent total enclosures, capture efficiency shall be assumed as 100%. Method 204 in 40 CFR Part 51, Appendix M, incorporated by reference in s. NR 484.04, shall be used to confirm that an enclosure meets the requirements for permanent total enclosure.

NR 466.09(5)(b)(b) For temporary total enclosures, the capture efficiency shall be determined according to Method 204 and, as applicable, Methods 204A through 204F, in 40 CFR Part 51, Appendix M, incorporated by reference in s. NR 484.04. The owner or operator may exclude never-controlled work stations from the capture efficiency determinations.

NR 466.09(6)(6) Alternative capture efficiency. As an alternative to the procedures specified in sub. (5), an owner or operator required to conduct a capture efficiency test may use any capture efficiency protocol and test methods that satisfy the criteria of either the data quality objective (DQO) or the lower confidence limit (LCL) approach in 40 CFR Part 63, Subpart KK, Appendix A, incorporated by reference in s. NR 484.04. The owner or operator may exclude never-controlled work stations from the capture efficiency determinations.

NR 466.10NR 466.10 Monitoring requirements. Following the date on which the initial performance test of a control device is completed, to demonstrate continuing compliance with the standard, the owner or operator shall monitor and inspect each control device required to comply with s. NR 466.06 or 466.07 to ensure proper operation and maintenance by implementing the applicable requirements in this section. Any excursion from the required operating parameters which are monitored in accordance with this section, unless otherwise excused, shall be considered a violation of the emission standard.

NR 466.10(1)(1) Owners or operators of product and packaging rotogravure or wide-web flexographic presses with intermittently-controllable work stations shall implement one of the following procedures for each dryer associated with a work station:

NR 466.10(1)(a)(a) 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. The 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 466.10(1)(b)(b) 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 466.10(1)(c)(c) Ensure that any bypass line valve or damper is in the closed position through continuous monitoring of the valve position. The monitoring system shall be inspected at least once every month to ensure that it is functioning properly.

NR 466.10(1)(d)(d) Use an automatic shutdown system in which the press is stopped when flow is diverted away from the control device to any bypass line. The automatic system shall be inspected at least once every month to ensure that it is functioning properly.

NR 466.10(2)(2) All continuous emission monitors shall comply with performance specifications (PS) 8 or 9 in 40 CFR Part 60, Appendix B, incorporated by reference in s. NR 484.04. The requirements of 40 CFR Part 60, Appendix F, incorporated by reference in s. NR 484.04, shall also be followed. In conducting the quarterly audits required by Appendix F, owners or operators shall challenge the monitors with compounds representative of the gaseous emission stream being controlled.

NR 466.10(3)(3) All temperature monitoring equipment shall be installed, calibrated, maintained and operated according to manufacturer’s specifications. The calibration of the chart recorder, data logger or temperature indicator shall be verified every 3 months. The owner or operator shall replace the chart recorder, data logger or temperature indicator if either the owner or operator chooses not to perform the calibration, or the equipment cannot be calibrated properly.

NR 466.10(4)(4) An owner or operator complying with s. NR 466.06 or 466.07 through continuous emission monitoring of a control device shall install, calibrate, operate and maintain continuous emission monitors to measure the total organic volatile matter concentration at both the control device inlet and outlet.

NR 466.10(5)(5) An owner or operator complying with the requirements of s. NR 466.06 or 466.07 through the use of an oxidizer and demonstrating continuous compliance through monitoring of an oxidizer operating parameter shall do the following as appropriate:

NR 466.10(5)(a)(a) 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 be accurate to within ±1% of the temperature being monitored in °C or ± 1°C, whichever is the greater value. The thermocouple or temperature sensor shall be installed in the combustion chamber at a location in the combustion zone.

NR 466.10(5)(b)(b) For a catalytic oxidizer, install, calibrate, operate and maintain a temperature monitoring device equipped with a continuous recorder. The device shall be accurate to within ±1% of the temperature being monitored in °C or ± 1°C, whichever is the greater value. The thermocouple or temperature sensor shall be installed in the vent stream at the nearest feasible point to the catalyst bed inlet.

NR 466.10(6)(6) An owner or operator, complying with the requirements of s. NR 466.06 or 466.07 through the use of a control device and demonstrating continuous compliance by monitoring an operating parameter to ensure that the capture efficiency measured during the initial compliance test is maintained, shall do all of the following:

NR 466.10(6)(a)(a) Submit to the department, with the compliance status report required by s. NR 460.08 (8), a plan that does all of the following:
