Current through June 24, 2024
(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.
(2) IF I USE A
				  CONTROL DEVICE TO COMPLY WITH THE EMISSION STANDARDS, WHAT MONITORING MUST I
				  DO?
(a) Summary. A summary of monitoring you
				  shall do follows:
Monitoring Summary
If you operate a web coating line, and you
								  have the following:
Then you shall:
1. Intermittently-controlled work stations
Record parameters related to possible exhaust
								  flow bypass of control device and to coating use (par. (c))
2. Solvent recovery unit
Operate continuous emission monitoring system and
								  perform quarterly audits or determine volatile matter recovered and conduct a
								  liquid-liquid material balance (par. (d))
3. Control device
Operate continuous parameter monitoring system
								  (par. (e))
4. Capture system
Monitor capture system operating parameter (par.
								  (f))
(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).
(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.
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.
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.
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.
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.
(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.
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.
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).
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.
c. You shall have valid
				  data from at least 90% of the hours during which the process is
				  operated.
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.
(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.
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.
2. You shall have
				  valid data from at least 90% of the hours during which the process
				  operated.
3. You shall determine
				  the hourly average of all recorded readings according to subd. 3. a. and b.
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.
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.
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.
5. You shall record the results of each
				  inspection, calibration and validation check of the CPMS.
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.
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.
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).
9. If you are using an oxidizer to comply
				  with the emission standards, you shall comply with subd. 9. a. to c.
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.
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.
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.
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).
(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.
1.
				  The monitoring plan shall do all of the following:
a. Identify the operating parameter to be
				  monitored to ensure that the capture efficiency determined during the initial
				  compliance test is maintained.
b.
				  Explain why the operating parameter is appropriate for demonstrating ongoing
				  compliance.
c. Identify the
				  specific monitoring procedures.
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.
3. You shall conduct all capture system
				  monitoring in accordance with the plan.
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.
5. You shall review and update the capture
				  system monitoring plan at least annually.
