NR 440.705(4)(c)1.a.a. The flow indicator shall be installed at the entrance to any bypass line that could divert the vent stream from being routed to the boiler or process heater, resulting in its emission to the atmosphere.
NR 440.705(4)(c)1.b.b. Where the bypass line valve is secured in the closed position with a car-seal or a lock-and-key type configuration, a flow indicator is not required. A visual inspection of the seal or closure mechanism shall be performed at least once every month to ensure that the valve is maintained in the closed position and the vent stream is not diverted through the bypass line.

Any vent stream introduced with primary fuel into a boiler or process heater is exempt from this requirement.
NR 440.705(4)(d)(d) The owner or operator of an affected facility that seeks to demonstrate compliance with the TRE index value limit specified under sub. (3) (c) shall install, calibrate, maintain and operate according to manufacturer’s specifications the following equipment unless alternative monitoring procedures or requirements are approved for that facility by the department:
NR 440.705(4)(d)1.1. Where an absorber is the final recovery device in the recovery system:
NR 440.705(4)(d)1.a.a. A scrubbing liquid temperature monitoring device having an accuracy of ± 1% of the temperature being monitored expressed in degrees Celsius or ± 0.5°C, whichever is greater, and a specific gravity monitoring device having an accuracy of ± 0.02 specific gravity units, each equipped with a continuous recorder; or
NR 440.705(4)(d)1.b.b. An organic monitoring device used to indicate the concentration level of organic compounds exiting the recovery device based on a detection principle such as infrared, photoionization or thermal conductivity, each equipped with a continuous recorder.
NR 440.705(4)(d)2.2. Where a condenser is the final recovery device in the recovery system:
NR 440.705(4)(d)2.a.a. A product side condenser exit temperature monitoring device equipped with a continuous recorder and having an accuracy of ± 1% of the temperature being monitored expressed in degrees Celsius or ± 0.5°C, whichever is greater; or
NR 440.705(4)(d)2.b.b. An organic monitoring device used to indicate the concentration level of organic compounds exiting the recovery device based on a detection principle such as infrared, photoionization or thermal conductivity, each equipped with a continuous recorder.
NR 440.705(4)(d)3.3. Where a carbon adsorber is the final recovery device unit in the recovery system:
NR 440.705(4)(d)3.a.a. An integrating steam flow monitoring device having an accuracy of ± 10% and a carbon bed temperature monitoring device having an accuracy of ± 1% of the temperature being monitored expressed in degrees Celsius or ±0.5°C, whichever is greater, both equipped with a continuous recorder; or
NR 440.705(4)(d)3.b.b. An organic monitoring device used to indicate the concentration level of organic compounds exiting the recovery device based on a detection principle such as infrared, photoionization or thermal conductivity, each equipped with a continuous recorder.
NR 440.705(4)(e)(e) An owner or operator of an affected facility seeking to demonstrate compliance with the standards specified under sub. (3) with a control device other than an incinerator, boiler, process heater or flare, or a recovery device other than an absorber, condenser or carbon adsorber, shall provide to the administrator information describing the operation of the control device or recovery device and the process parameters which would indicate proper operation and maintenance of the device. The administrator may request further information and will specify appropriate monitoring procedures or requirements.
NR 440.705(5)(5)Test methods and procedures.
NR 440.705(5)(a)(a) For the purpose of demonstrating compliance with sub. (3), all affected facilities shall be run at full operating conditions and flow rates during any performance test.
NR 440.705(5)(b)(b) The following methods in Appendix A of 40 CFR part 60, incorporated by reference in s. NR 440.17, except as provided under s. NR 440.08 (2), shall be used as reference methods to determine compliance with the emission limit or percent reduction efficiency specified under sub. (3) (a):
NR 440.705(5)(b)1.1. Method 1 or 1A, as appropriate, for selection of the sampling sites. The control device inlet sampling site for determination of vent stream molar composition or TOC, less methane and ethane, reduction efficiency shall be prior to the inlet of the control device and after the recovery system.
NR 440.705(5)(b)2.2. Method 2, 2A, 2C or 2D, as appropriate, for determination of the gas volumetric flow rates.
NR 440.705(5)(b)3.3. The emission rate correction factor, integrated sampling and analysis procedure of Method 3B shall be used to determine the oxygen concentration (%O2d) for the purposes of determining compliance with the 20 ppmv limit. The sampling site shall be the same as that of the TOC samples, and the samples shall be taken during the same time that the TOC samples are taken. The TOC concentration corrected to 3% O2 (Cc) shall be computed using the following equation:
where:
Cc is the concentration of TOC corrected to 3% O2, dry basis ppm by volume
CTOC is the concentration of TOC minus methane and ethane, dry basis ppm by volume
%O2d is the concentration of O2, dry basis percent by volume
NR 440.705(5)(b)4.4. Method 18 to determine the concentration of TOC in the control device outlet and the concentration of TOC in the inlet when the reduction efficiency of the control device is to be determined.
NR 440.705(5)(b)4.a.a. The minimum sampling time for each run shall be one hour in which either an integrated sample or 4 grab samples shall be taken. If grab sampling is used, then the samples shall be taken at approximately 15-minute intervals.
NR 440.705(5)(b)4.b.b. The emission reduction (R) of TOC, minus methane and ethane, shall be determined using the following equation:
where:
R is the emission reduction, percent by weight
Ei is the mass rate of TOC entering the control device, kg TOC/hr
