Table 7 to Subpart PPP of Part 63 - Operating Parameters for Which Monitoring Levels Are Required To Be Established for Process Vent Streams
Control technique 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.
Absorber Liquid flow rate or pressure drop; and pH of scrubber effluent, if an acid or base absorbent is used Minimum flow rate or pressure drop; and maximum pH if an acid absorbent is used, or minimum pH if a base absorbent is used.
Condenser Exit temperature Maximum temperature.
Carbon adsorber Total regeneration stream mass or volumetric flow during carbon bed regeneration cycle; and temperature of the carbon bed after regeneration (and within 15 minutes of completing any cooling cycle(s)) Maximum mass or volumetric flow; and maximum temperature.
Extended Cookout (ECO) Time from the end of the epoxide feed to the end of the ECO, or the reactor epoxide partial pressure at the end of the ECO, or the epoxide concentration in the reactor liquid at the end of the ECO Minimum duration, or maximum partial pressure at the end of ECO, or maximum epoxide concentration in the reactor liquid at the end of ECO.
Other devices (or as an alternate to the above). a HAP concentration level or reading at outlet of device Maximum HAP concentration or reading.

a Concentration is measured instead of an operating parameter.
