40 CFR Appendix Table 7 to Subpart U of Part 63, Operating Parameters for Which Monitoring Levels Are Required To Be Established for Continuous and Batch Front-End Process Vents and Aggregate Batch Vent Streams

Table 7 to Subpart U of Part 63 - Operating Parameters for Which Monitoring Levels Are Required To Be Established for Continuous and Batch Front-End Process Vents and Aggregate Batch Vent Streams
Control/recovery 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
[§ 63.489(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 above) 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.
