Permit Unit Requirements for N-4070-1-11 (continued) Page 8 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 65. For the enclosed flare, permittee shall install, calibrate, maintain, and operate, according to the manufacturer's specifications, a temperature monitoring device equipped with a continuous recorder. The temperature monitoring device shall have a minimum accuracy of plus or minus 1% of the temperature being measured expressed in degrees Celsius or plus or minus 0.5 degrees Celsius, whichever is greater. [40 CFR 63.1961(b)(1)] Federally Enforceable Through Title V Permit 66. Permittee shall install, calibrate, maintain, and operate a device that records flow to or bypass of the control device. This device may be a meter that measures and records the landfill gas flow rate into the flare at least once every 15 minutes, and is also capable of measuring the landfill gas flow rate that might bypass the flare in the event of equipment malfunction or maintenance. Alternatively, this device may secure the bypass line valve in the closed position and shall be inspected at least once every month to ensure that the valve is maintained in the closed position. [40 CFR 63.1961(b)(2)] Federally Enforceable Through Title V Permit 67. If the landfill is closed, as defined in 40 CFR 63.1990, and the landfill has no monitored exceedances of the surface methane operational standard in three consecutive quarterly monitoring periods, permittee may change surface methane concentration monitoring to an annual basis. Any methane reading of 500 ppm or more above background detected during annual monitoring returns the frequency for that landfill back to quarterly monitoring. [40 CFR 63.1961(f)] Federally Enforceable Through Title V Permit 68. If the landfill is permanently closed, a closure notification shall be submitted to the APCO within 30 days of waste disposal cessation. A permanent closure shall take place in accordance with 40 CFR 258.60. If a closure report has been submitted, no additional waste may be placed in the landfill without filing a notification of modification to the APCO, as described under 40 CFR 63.9(b). [40 CFR 63.1959(b)(1)(ii)(B) and 40 CFR 63.1981(f)] Federally Enforceable Through Title V Permit 69. The owner or operator shall submit a revised design plan at least 90 days before expanding operations to an area not covered by the previously approved design plan or prior to installing or expanding the gas collection system in a way that is not consistent with the previously approved design plan. [40 CFR 63.1981(e)] Federally Enforceable Through Title V Permit 70. The owner or operator shall submit an equipment removal report to the APCO no less than 30 days prior to removal or cessation of operation of the control equipment. The equipment removal shall contain the following: (1) A copy of the closure report; (2) A copy of the initial performance test demonstrating that the 15-year minimum control period has expired, or information that demonstrates that the gas collection and control system will be unable to operate for 15 years due to declining gas flows; (3) Dated copies of three successive NMOC emission rate reports demonstrating that the landfill is no longer producing 50 Mg or greater of NMOC per year. The APCO may request additional information if deemed necessary to verify that all conditions for removal have been met. [40 CFR 63.1981(g)] Federally Enforceable Through Title V Permit 71. Permittee shall submit a semi-annual report every 6 months to the APCO. The semi-annual report shall include the following: (1) Number of times the collection system is operated with a positive pressure, number of times the monitored landfill gas temperature exceeds 62.8 degrees Celsius (145 degrees Fahrenheit), number of times the surface methane concentration is equal to or exceeds 500 ppm above background, a description of all periods when the control system is not operating, and the date, time, and duration of each of these instances, (2) Description and duration of all periods when the landfill gas stream is diverted from the control device through a bypass line, (3) All periods when the collection system was not operating, (4) Location of each exceedance of the 500-ppm surface methane operational standard with the accuracy provided in the condition referencing 40 CFR 1958(d) in this permit and the concentration recorded at the location of the exceedance in the previous month, (5) The date of installation and location of each well or collection system expansion added, (6) Any corrective action analysis, root cause analysis and corresponding implementation schedule as required for exceedances of the landfill gas temperature operational standard, and (7) For enhanced monitoring activities as provided in the conditions that reference 40 CFR 63.1961(a)(5) in this permit, the date, time, staff person name, a description of findings for each visual observation for subsurface oxidation event, and well identifier along with the value and units of measure of oxygen concentration, temperature, methane concentration, carbon monoxide concentration, and a summary trend analysis for each well to chart weekly readings of the monitored parameters.
