Appendix Table 4 to Subpart OOO of Part 63 - Operating Parameter Levels

DeviceParameters to be monitoredEstablished operating parameter(s)
ScrubberpH of scrubber effluent; and scrubber liquid and gas flow ratesMinimum pH; and minimum liquid/gas ratio
AbsorberExit temperature of the absorbing liquid; and exit specific gravity of the absorbing liquidMaximum temperature; and maximum specific gravity
CondenserExit temperatureMaximum temperature
Carbon absorberTotal regeneration steam or nitrogen flow, or pressure (gauge or absolute) aduring 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
Thermal incineratorFirebox temperatureMinimum temperature
Catalytic incineratorTemperature upstream and downstream of the catalyst bedMinimum upstream temperature; and minimum temperature difference across the catalyst bed
Boiler or process heaterFirebox temperatureMinimum temperature
Other devices (or as an alternate to the requirements previously presented in this table) bOrganic HAP concentration level or reading at outlet of deviceMaximum organic 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.
