Table 4 to Subpart OOO of Part 63—Operating Parameter Levels
Parameters to be monitored
Established operating parameter(s)
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.
pH of scrubber effluent; and scrubber liquid and gas flow rates
Minimum pH; and minimum liquid/gas ratio
Exit temperature of the absorbing liquid; and exit specific gravity of the absorbing liquid
Maximum temperature; and maximum specific gravity
Total regeneration steam 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
Temperature upstream and downstream of the catalyst bed
Minimum upstream temperature; and minimum temperature difference across the catalyst bed
Boiler or process heater
Other devices (or as an alternate to the requirements previously presented in this table) b
Organic HAP concentration level or reading at outlet of device
Maximum organic HAP concentration or reading
