6. Report all operating days when insufficient monitoring data are collected.f

Boiler or process heater with a design heat input capacity less than 44 megawatts and vent stream is not introduced with or as the primary fuelFirebox temperature b [63.114(a)(3)]1. Continuous records.

2. Record and report the firebox temperature averaged over the full period of the performance test—NCS.

3. Record the daily average firebox temperature for each operating day.e

4. Report all daily average firebox temperatures that are outside the range established in the NCS or operating permit and all operating days when insufficient monitoring data are collected f—PR.

FlarePresence of a flame at the pilot light [63.114(a)(2)]1. Hourly records of whether the monitor was continuously operating and whether the pilot flame was continuously present during each hour.

2. Record and report the presence of a flame at the pilot light over the full period of the compliance determination—NCS.

3. Record the times and durations of all periods when all pilot flames are absent or the monitor is not operating.

4. Report the times and durations of all periods when all pilot flames of a flare are absent—PR.

Recapture devicesThe appropriate monitoring device identified in table 4 when, in the table, the term “recapture” is substituted for “recovery.” [63.114(a)(5)]1. The recordkeeping and reporting requirements for monitored parameters identified for the appropriate monitoring device in table 4 of this subpart.

Scrubber for halogenated vent streams (Note: Controlled by a combustion device other than a flare)pH of scrubber effluent [63.114(a)(4)(i)], and1. Continuous records.

2. Record and report the pH of the scrubber effluent averaged over the full period of the performance test—NCS.

3. Record the daily average pH of the scrubber effluent for each operating day.e

4. Report all daily average pH values of the scrubber effluent that are outside the range established in the NCS or operating permit and all operating days when insufficient monitoring data are collected f—PR.

Scrubber for halogenated vent streams (Note: Controlled by a combustion device other than a flare) (Continued)Scrubber liquid and gas flow rates [63.114(a)(4)(ii)]1. Continuous records of scrubber liquid flow rate.

2. Record and report the scrubber liquid/gas ratio averaged over the full period of the performance test—NCS.

3. Record the daily average scrubber liquid/gas ratio for each operating day.e

4. Report all daily average scrubber liquid/gas ratios that are outside the range established in the NCS or operating permit and all operating days when insufficient monitoring data are collected f—PR.

All control devicesPresence of flow diverted to the atmosphere from the control device [63.114(d)(1)] or1. Hourly records of whether the flow indicator was operating and whether diversion was detected at any time during each hour.

2. Record and report the times and durations of all periods when the vent stream is diverted through a bypass line or the monitor is not operating—PR.

Monthly inspections of sealed valves [63.114(d)(2)]1. Records that monthly inspections were performed.

2. Record and report all monthly inspections that show the valves are moved to the diverting position or the seal has been changed—PR.

a Regulatory citations are listed in brackets.

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

c“Continuous records” is defined in § 63.111 of this subpart.

d NCS=Notification of Compliance Status described in § 63.152 of this subpart.

e The daily average is the average of all recorded parameter values for the operating day. If all recorded values during an operating day are within the range established in the NCS or operating permit, a statement to this effect can be recorded instead of the daily average.

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

g PR=Periodic Reports described in § 63.152 of this subpart.
