Control device Reporting requirements
(1) Thermal IncineratorReport all daily averagea temperatures that are outside the range established in the NCSb or operating permit and all operating days when insufficient monitoring data are collected.c
(2) Catalytic Incinerator(i) Report all daily averagea upstream temperatures that are outside the range established in the NCSb or operating permit.
(ii) Report all daily averagea temperature differences across the catalyst bed that are outside the range established in the NCSb or operating permit.
(iii) Report all operating days when insufficient monitoring data are collected.c
(3) Boiler or Process Heater with a design heat input capacity less than 44 megawatts and vent stream is not mixed with the primary fuelReport all daily averagea firebox temperatures that are outside the range established in the NCSb or operating permit and all operating days when insufficient monitoring data are collected.c
(4) FlareReport the duration of all periods when all pilot flames are absent.
(5) CondenserReport all daily averagea exit temperatures that are outside the range established in the NCSb or operating permit and all operating days when insufficient monitoring data are collectedc.
(6) Carbon Adsorber (Regenerative)(i) Report all carbon bed regeneration cycles when the total regeneration stream mass or volumetric flow is outside the range established in the NCSb or operating permit.
(ii) Report all carbon bed regeneration cycles during which the temperature of the carbon bed after regeneration is outside the range established in the NCSb or operating permit.
(iii) Report all operating days when insufficient monitoring data are collectedc.
(7) Carbon Adsorber (Non-Regenerative)(i) Report all operating days when inspections not done according to the schedule developed as specified in table 13 of this subpart.
(ii) Report all operating days when carbon has not been replaced at the frequency specified in table 13 of this subpart.
(8) All Control Devices(i) Report the times and durations of all periods when the vent stream is diverted through a bypass line or the monitor is not operating, or
(ii) Report all monthly inspections that show the valves are moved to the diverting position or the seal has been changed.

a The daily average is the average of all values recorded during the operating day, as specified in § 63.147(d) .

b NCS = Notification of Compliance Status described in § 63.152 .

c The periodic reports shall include the duration of periods when monitoring data are not collected for each excursion as defined in § 63.152(c)(2)(ii)(A) .
