A flow indicator that provides a record of vent stream flow diverted from being routed to the flare at least once every 15 minutes for each affected facility, except as provided in subd. 2. b. NR 440.705(4)(b)2.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 flare, resulting in its emission to the atmosphere. NR 440.705(4)(b)2.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. NR 440.705(4)(c)(c) The owner or operator of an affected facility that uses a boiler or process heater to seek to comply with sub. (3) (a) shall install, calibrate, maintain and operate according to the manufacturer’s specifications the following equipment: NR 440.705(4)(c)1.1. A flow indicator that provides a record of vent stream flow diverted from being routed to the boiler or process heater at least once every 15 minutes for each affected facility, except as provided in subd. 1. b. 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. NR 440.705(4)(c)2.2. A temperature monitoring device in the firebox 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, for boilers or process heaters of less than 44 MW (150 million Btu/hr) design heat input capacity. 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.
