Table 2 to Subpart NNNa of Part 60—Monitoring Requirements for Complying With 98 Weight-Percent Reduction of Total Organic Compounds Emissions or a Limit of 20 Parts per Million by Volume

Non-flare control device or recovery device	Parameters to be monitored
1. All control and recovery devices	a. Presence of flow diverted to the atmosphere from the control and recovery device; or
	b. Monthly inspections of sealed valves
2. Absorber	a. 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 fuel	Firebox temperaturea
4. Catalytic incinerator	Temperature upstream and downstream of the catalyst bed
5. Carbon adsorber, regenerative	a. 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 offsite	Breakthrough
7. Condenser	Exit (product side) temperature
8. Scrubber for halogenated vent streams	a. pH of scrubber effluent; and
	b. Scrubber liquid and gas flow rates
9. Thermal incinerator	Firebox temperaturea
10. Control devices other than an incinerator, boiler, process heater, or flare; or recovery devices other than an absorber, condenser, or carbon adsorber	As 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.
