(v) Monitoring data recorded during periods of monitoring system break-downs, repairs, calibration checks, and zero (low-level) and high-level adjustments shall not be included in any average computed under this subpart. Records shall be kept of the times and durations of all such periods and any other periods during process or control device operation when monitors are not operating.

(4) All other information required to be reported under paragraphs (a) through (h) of this section shall be retained for 5 years.

TABLE 10.--MISCELLANEOUS PROCESS VENTS--MONITORING, RECORDKEEPING AND REPORTING REQUIREMENTS FOR COMPLYING WITH 98 WEIGHT-PERCENT REDUCTION OF TOTAL ORGANIC HAP EMISSIONS OR A LIMIT OF 20 PARTS PER MILLION BY VOLUME

Control device	Parameters to be monitored ^a	Recordkeeping and reporting requirements for monitored parameters
Thermal incinerator	Firebox temperature^b (63.644(a)(1)(I)).	Continuous records^c. Record and report the firebox temperature averaged over the full period of the performance test--NCS^d. Record the daily average firebox temperature for each operating day^e. Report all daily average 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^g.
Catalytic incinerator	Temperature upstream and downstream of the catalyst bed (63.644(a)(1)(ii)).	Continuous records^c. Record and report the upstream and downstream temperatures and the temperature difference across the catalyst bed averaged over the full period of the performance test--NCS^d. Record the daily average upstream temperature and temperature difference across the catalyst bed for each operating day^e. Report all daily average upstream temperatures that are outside the range established in the NCS or operating permit--PR^g. Report all daily average temperature differences across the catalyst bed that are outside the range establsihed in the NCS or operating permit--PR^g. Report all operating days when insufficient monitoring data are collected^f.
Boiler or process heater with a design heat capacity less than 44 megawatts where the vent stream is not introduced into the flame zone ^h,i	Firebox temperature ^h (63.644(a)(4)).	Continuous records^c. Record and report the firebox temperature averaged over the full period of the performance test--NCS^d. Record the daily average firebox temperature for each operating day^e. 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^g.
Flare	Presence of a flame at the pilot light (63.644(a)(2)).	Hourly records of whether the monitor was continuously operating and whether a pilot flame was continuously present during each hour. Record and report the presence of a flame at the pilot light over the full period of the compliance determination--NCS^d. Record the times and durations of all periods when all pilot flames for a flare are absent or the monitor is not operating.
All control devices	Presence of flow diverted to the atmosphere from the control device (63.644(c)(1)) or.	Hourly records of whether the flow indicator was operating and whether flow was detected at any time during each hour. 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^g.
Monthly inspections of sealed valves (63.644(c)(2)).	Records that monthly inspections were performed. Record and Report all monthly inspections that show the valves are not closed or the seal has been changed--PR^g.

^ARegulatory citations are listed in parentheses.

^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 § 63.641.

^D NCS = Notification of compliance status report described in § 63.654.

^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 When a period of excess emission is caused by insufficient monitoring data, as described in § 63.654(g)(6)(8) (C) or (D), the duration of the period when monitoring data were not collected shall be included in the Periodic Report.

^G PR = Period Reports described in § 63.654(g).

^H No monitoring is required for boilers and process heaters with a design heat capacity 44 megawatts or for boilers and process heaters where all vent streams are introduced into the flame zone. No recordkeeping or reporting associated with monitoring is required for such boilers and process heaters.

^I Process vents that are routed to refinery fuel gas systems are not regulated under this subpart. No monitoring, recordkeeping, or reporting is required for boilers and process heaters that combust refinery fuel gas.
