Table 4 to Subpart OOO of Part 63 - Operating Parameter Levels
|Device||Parameters to be monitored||Established operating
|Scrubber||pH of scrubber effluent; and scrubber liquid and gas flow rates||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 absorber||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|
|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|
|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|
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.
