40 CFR 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.
