40 CFR Appendix Table 8 to Subpart JJJ of Part 63 - Table 8 to Subpart JJJ of Part 63—Operating Parameters for Which Levels Are Required To Be Established for Continuous and Batch Process Vents and Aggregate Batch Vent Streams

Device	Parameters to be monitored	Established operating parameter(s)
Thermal incinerator	Firebox temperature	Minimum temperature.
Catalytic incinerator	Temperature upstream and downstream of the catalyst bed	Minimum upstream temperature; and minimum temperature difference across the catalyst bed.
Boiler or process heater	Firebox temperature	Minimum temperature.
Scrubber for halogenated vents	pH of scrubber effluent; and scrubber liquid and gas flow rates [§ 63.1324(b)(4)(ii)]	Minimum pH; and minimum liquid/gas ratio.
Absorber	Exit temperature of the absorbing liquid; and exit specific gravity of the absorbing liquid	Maximum temperature; and maximum specific gravity.
Condenser	Exit temperature	Maximum temperature.
Carbon adsorber	Total regeneration steam flow or nitrogen flow, or pressure (gauge or absolute) a during carbon bed regeneration cycle; and temperature of the carbon bed after regeneration (and within 15 minutes of completing any cooling cycle(s))	Maximum flow or pressure; and maximum temperature.
Other devices (or as an alternate to the requirements previously presented in this table) b	HAP concentration level or reading at outlet of device	Maximum HAP concentration or reading.

a 25 to 50 mm (absolute) is a common pressure level obtained by pressure swing absorbers.

b Concentration is measured instead of an operating parameter.
