Non-flare control device or recovery device Parameters to be monitored
1. All control and recovery devicesa. Presence of flow diverted to the atmosphere from the control and recovery device; or
b. Monthly inspections of sealed valves.
2. Absorbera. Exit temperature of the absorbing liquid; and
b. Exit specific gravity.
3. Boiler or process heater with a design heat input capacity less than 44 megawatts and vent stream is not introduced with or as the primary fuelFirebox temperature. a
4. Catalytic incineratorTemperature upstream and downstream of the catalyst bed.
5. Carbon adsorber, regenerativea. Total regeneration stream mass or volumetric flow during carbon bed regeneration cycle(s); and
b. Temperature of the carbon bed after regeneration [and within 15 minutes of completing any cooling cycle(s)].
6. Carbon adsorber, non-regenerative or regenerated offsiteBreakthrough.
7. CondenserExit (product side) temperature.
8. Scrubber for halogenated vent streamsa. pH of scrubber effluent; and
b. Scrubber liquid and gas flow rates.
9. Thermal incineratorFirebox temperature. a
10. Control devices other than an incinerator, boiler, process heater, or flare; or recovery devices other than an absorber, condenser, or carbon adsorberAs specified by the Administrator.

a Monitor may be installed in the firebox or in the ductwork immediately downstream of the firebox before any substantial heat exchange is encountered.
