Permit Unit Requirements for N-4070-1-11 (continued) Page 2 of 14 PERMIT UNIT REQUIREMENTS CONTINUE ON NEXT PAGE These terms and conditions are part of the Facility-wide Permit to Operate. Facility Name: FOOTHILL SANITARY LANDFILL Location: 6484 N WAVERLY RD,LINDEN, CA 95236 N-4070-1-11 : 9/24/2025 3:25:45 PM -- ROBINSOM 12. The methane destruction efficiency for the enclosed flare shall be at least 99% by weight. [17 CCR 95464] Federally Enforceable Through Title V Permit 13. A flame shall be present at all times when combustible gases are being vented through the flare. [District Rule 4311] Federally Enforceable Through Title V Permit 14. The flare outlet shall be equipped with an automatic ignition system, or shall operate with a pilot flame present at all times when combustible gases are vented through the flare, except during purge periods for automatic-ignition equipped flares. [District Rule 4311] Federally Enforceable Through Title V Permit 15. Unless the flare is equipped with a flow-sensing ignition system, the flare shall be equipped and operated with a heat sensing device such as a thermocouple, ultraviolet beam sensor, infrared sensor, or an equivalent device, capable of continuously detecting at least one pilot flame or the flare flame is present. [District Rule 4311] Federally Enforceable Through Title V Permit 16. Flares that use flow-sensing automatic ignition systems and which do not use a continuous flame pilot shall use purge gas for purging. [District Rule 4311] Federally Enforceable Through Title V Permit 17. For the flare, the operator shall monitor the volumetric flows of purge and pilot gases with flow measuring devices or other parameters may be monitored so that the volumetric flows of pilot and purge gases may be calculated based on the parameters monitored. [District Rule 4311] Federally Enforceable Through Title V Permit 18. The operator shall maintain and calibrate all required monitors and recording devices in accordance with the applicable manufacturer's specifications. In order to claim that a manufacturer's specification is not applicable, the person responsible for emissions shall have, and follow, a written maintenance policy that was developed for the device in question. The written policy shall explain and justify the difference between the written procedure and the manufacturer's procedure. [District Rule 4311] Federally Enforceable Through Title V Permit 19. For the flare, all in-line continuous analyzer and flow monitoring data shall be continuously recorded by an electronic data acquisition system capable of one-minute averages. Flow monitoring data shall be recorded as one-minute averages. [District Rule 4311] Federally Enforceable Through Title V Permit 20. The operator shall maintain a record of data collected from monitoring the volumetric flows of the pilot and purge gas for the flare. [District Rule 4311] Federally Enforceable Through Title V Permit 21. The operator shall maintain a record of source testing results performed to demonstrate compliance with the NOx and VOC emission limits. [District Rule 4311] Federally Enforceable Through Title V Permit 22. Periods in which the flare monitoring system is not operating greater than 24 continuous hours shall be reported to the District by the following working day and followed by a notification of resumed operation of the flare monitoring system. Periods in which the flare monitoring system is not operating shall not exceed 14 days in any 18-consecutive- month period. Periods in which the flare monitoring system is not operating do not include periods when the system feeding the flare is not operating. [District Rule 4311] Federally Enforceable Through Title V Permit 23. The operator shall submit an annual report in an electronic format approved by the District to the APCO within 30 days following the end of each calendar year. The annual monitoring report shall include the following: (1) The type of purge and pilot gas used, the volumetric flow of purge and pilot gas for each day and for each month, and the means used to determine flow; (2) Dates and times of flare monitoring system downtime periods. [District Rule 4311] Federally Enforceable Through Title V Permit 24. The operator shall maintain a record of annual monitoring reports submitted to the APCO as required by this permit. [District Rule 4311] Federally Enforceable Through Title V Permit 25. Source testing of the flare shall be performed to demonstrate compliance with the NOx and CO emission rates (in lb/MMBtu), and VOC control efficiency of 98% or 20 ppmvd VOC @ 3% O2 as hexane within 60 days of initial startup and at least once every 12 months thereafter. The VOC Control Efficiency = (NMOC(in) - NMOC(out))/NMOC(in), where NMOC(in) is the mass of NMOC entering the flare and NMOC(out) is the mass of NMOC exiting the flare. [District Rules 1080, 2201, and 4311; and 40 CFR 63 Subpart AAAA] Federally Enforceable Through Title V Permit
