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
|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.
