40 CFR Table 2 to Subpart RRRa of Part 60: Table 2 to Subpart RRRa 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 temperature a

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 temperature a

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.
