Each owner or operator shall either: NR 440.675(3)(a)(a) Reduce emissions of TOC (minus methane and ethane) by 98 weight- percent or to a TOC (minus methane and ethane) concentration of 20 ppmv on a dry basis corrected to 3% oxygen, whichever is less stringent. If a boiler or process heater is used to comply with this paragraph, then the vent stream shall be introduced into the flame zone of the boiler or process heater; or NR 440.675(3)(c)(c) Maintain a TRE index value greater than 1.0 without use of VOC emission control devices. NR 440.675(4)(a)(a) The owner or operator of an affected facility that uses an incinerator to seek to comply with the TOC emission limit specified under sub. (3) (a) shall install, calibrate, maintain and operate according to manufacturer’s specifications the following equipment: NR 440.675(4)(a)1.1. A 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. NR 440.675(4)(a)1.a.a. Where an incinerator other than a catalytic incinerator is used, a temperature monitoring device shall be installed in the firebox. NR 440.675(4)(a)1.b.b. Where a catalytic incinerator is used, temperature monitoring devices shall be installed in the gas stream immediately before and after the catalyst bed. NR 440.675(4)(a)2.2. A flow indicator that provides a record of vent stream flow to the incinerator at least once every hour for each affected facility. The flow indicator shall be installed in the vent stream from each affected facility at a point closest to the inlet of each incinerator and before being joined with any other vent stream.
