Carbon adsorber (regenerative)Integrating regeneration stream flow monitoring device having an accuracy of ± 10 percent, andTotal regeneration stream mass or volumetric flow during carbon bed regeneration cycle(s)For each regeneration cycle, record the total regeneration stream mass or volumetric flow.

Carbon bed temperature monitoring deviceTemperature of carbon bed after regeneration [and within 15 minutes of completing any cooling cycle(s)]For each regeneration cycle and within 15 minutes of completing any cooling cycle, record the carbon bed temperature.

Carbon adsorber (Non-regenerative)Organic compound concentration monitoring device. cOrganic compound concentration of adsorber exhaustDaily or at intervals no greater than 20 percent of the design carbon replacement interval, whichever is greater.

Alternative monitoring parametersOther parameters may be monitored upon approval from the Administrator in accordance with the requirements in §63.143(e)(3)

a Monitor may be installed in the firebox or in the ductwork immediately downstream of the firebox before any substantial heat exchange is encountered.

b “Continuous recorder” is defined in §63.111 of this subpart.

c As an alternative to conducting this monitoring, an owner or operator may replace the carbon in the carbon adsorption system with fresh carbon at a regular predetermined time interval that is less than the carbon replacement interval that is determined by the maximum design flow rate and organic concentration in the gas stream vented to the carbon adsorption system.
