- Table 3 to Subpart OOO of Part 63—Batch Process Vent Monitoring Requirements
| Control device | Parameters to be monitored | Frequency/recordkeeping requirements | Scrubber a | pH of scrubber effluent, and | Continuous records as specified in § 63.1416(d). b | Scrubber liquid and gas flow rates | Continuous records as specified in § 63.1416(d). b | Absorber a | Exit temperature of the absorbing liquid, and | Continuous records as specified in § 63.1416(d). b | Exit specific gravity for the absorbing liquid | Continuous records as specified in § 63.1416(d). b | Condenser a | Exit (product side) temperature | Continuous records as specified in § 63.1416(d). a | Carbon adsorber a | Total regeneration steam flow or nitrogen flow, or pressure (gauge or absolute) during carbon bed regeneration cycle(s), and | Record the total regeneration steam flow or nitrogen flow, or pressure for each carbon bed regeneration cycle. | Temperature of the carbon bed after regeneration and within 15 minutes of completing any cooling cycle(s) | Record the temperature of the carbon bed after each regeneration and within 15 minutes of completing any cooling cycle(s). | Thermal incinerator | Firebox temperature c | Continuous records as specified in § 63.1416(d). b | Catalytic incinerator | Temperature upstream and downstream of the catalyst bed | Continuous records as specified in § 63.1416(d). b | Boiler or process heater with a design heat input capacity less than 44 megawatts and where the batch process vents or aggregate batch vent streams are not introduced with or used as the primary fuel | Firebox temperature c | Continuous records as specified in § 63.1416(d). b | Flare | Presence of a flame at the pilot light | Hourly records of whether the monitor was continuously operating during batch emission episodes, or portions thereof, selected for control and whether a flame was continuously present at the pilot light during said periods. | All control devices | Diversion to the atmosphere from the control device or | Hourly records of whether the flow indicator was operating during batch emission episodes, or portions thereof, selected for control and whether a diversion was detected at any time during said periods as specified in § 63.1416(d). | Monthly inspections of sealed valves | Records that monthly inspections were performed as specified in § 63.1416(d). | Scrubber, absorber, condenser, and carbon adsorber (as an alternative to the requirements previously presented in this table) | Concentration level or reading indicated by an organic monitoring device at the outlet of the control device | Continuous records as specified in § 63.1416(d). b |

a Alternatively, these devices may comply with the organic monitoring device provisions listed at the end of this table.
b “Continuous records” is defined in § 63.111.
c Monitor may be installed in the firebox or in the ductwork immediately downstream of the firebox before any substantial heat exchange is encountered.
