40 CFR Appendix Table 3 to Subpart OOO of Part 63 - Table 3 to Subpart OOO of Part 63—Batch Process Vent Monitoring Requirements

Control device	Parameters to be monitored	Frequency/recordkeeping requirements
Scrubber a	pH of scrubber effluent, and	Continuous records as specified in § 63.1416(d). b
	Scrubber liquid and gas flow rates	Continuous records as specified in § 63.1416(d). b
Absorber a	Exit temperature of the absorbing liquid, and	Continuous records as specified in § 63.1416(d). b
	Exit specific gravity for the absorbing liquid	Continuous records as specified in § 63.1416(d). b
Condenser a	Exit (product side) temperature	Continuous records as specified in § 63.1416(d). a
Carbon adsorber a	Total regeneration steam flow or nitrogen flow, or pressure (gauge or absolute) during carbon bed regeneration cycle(s), and	Record the total regeneration steam flow or nitrogen flow, or pressure for each carbon bed regeneration cycle.
	Temperature of the carbon bed after regeneration and within 15 minutes of completing any cooling cycle(s)	Record the temperature of the carbon bed after each regeneration and within 15 minutes of completing any cooling cycle(s).
Thermal incinerator	Firebox temperature c	Continuous records as specified in § 63.1416(d). b
Catalytic incinerator	Temperature upstream and downstream of the catalyst bed	Continuous records as specified in § 63.1416(d). b
Boiler or process heater with a design heat input capacity less than 44 megawatts and where the batch process vents or aggregate batch vent streams are not introduced with or used as the primary fuel	Firebox temperature c	Continuous records as specified in § 63.1416(d). b
Flare	Presence of a flame at the pilot light	Hourly records of whether the monitor was continuously operating during batch emission episodes, or portions thereof, selected for control and whether a flame was continuously present at the pilot light during said periods.
All control devices	Diversion to the atmosphere from the control device or	Hourly records of whether the flow indicator was operating during batch emission episodes, or portions thereof, selected for control and whether a diversion was detected at any time during said periods as specified in § 63.1416(d).
	Monthly inspections of sealed valves	Records that monthly inspections were performed as specified in § 63.1416(d).
Scrubber, absorber, condenser, and carbon adsorber (as an alternative to the requirements previously presented in this table)	Concentration level or reading indicated by an organic monitoring device at the outlet of the control device	Continuous records as specified in § 63.1416(d). b

a Alternatively, these devices may comply with the organic monitoring device provisions listed at the end of this table.

b “Continuous records” is defined in § 63.111.

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