Current through August 26, 2024

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.

(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:

(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.

(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.

(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.

(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.

(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.

(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.

(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.

(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:

(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.

(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.

(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:

(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:
1. Identifies the operating parameter to be monitored to ensure that the capture efficiency measured during the initial compliance test is maintained.

2. Discusses why this parameter is appropriate for demonstrating ongoing compliance.

3. Identifies the specific monitoring procedures.

(b) Set the operating parameter value, or range of values, that demonstrate compliance with s. NR 466.06 or 466.07.

(c) Conduct monitoring in accordance with the plan submitted to the department unless comments received from the department require an alternate monitoring scheme.
