An initial source test must be conducted within 180 days of initial start up of the gas collection and control system. Each succeeding complete annual source test must be conducted no later than 45 days after the anniversary date of the initial source test. (A) If a gas control device remains in compliance after three consecutive source tests the owner or operator may conduct the source test every three years. If a subsequent source test shows the gas collection and control system is out of compliance the source testing frequency will return to annual. [17 CCR 95464 (b)(4)] Federally Enforceable Through Title V Permit 53.Methane surface concentration shall not exceed 500 ppmv as methane, other than non-repeatable, momentary readings, as determined by instantaneous surface monitoring. [17 CCR 95465(a)(1), 17 CCR 95468] Federally Enforceable Through Title V Permit 54.Methane average surface concentration shall not exceed 25 ppmv as determined by integrated surface monitoring. [17 CCR 95465(a)(2)] Federally Enforceable Through Title V Permit 55.Methane concentration limits do not apply to the working face of a landfill surface where the landfill cover material has been removed and refuse has been exposed for the purpose of installing, expanding, replacing, or repairing components of the landfill gas, leachate, or gas condensate collection and removal system, or for law enforcement activities requiring excavation. [17 CCR 95466(a)] Federally Enforceable Through Title V Permit 56.Any owner or operator of a MSW landfill with a gas collection and control system must conduct instantaneous and integrated surface monitoring of the landfill surface quarterly using the procedures specified in section 17 CCR 95471(c). Any reading exceeding a surface concentration of 500 ppmv as methane, other than non-repeatable, momentary readings and as determined by instantaneous surface monitoring, must be recorded as an exceedance and the following actions must be taken: (A) The owner or operator must record the date, location, and value of each exceedance, along with re-test dates and results. The location of each exceedance must be clearly marked and identified on a topographic map of the MSW landfill, drawn to scale with the location of both the grids and the gas collection system clearly identified, (B) Corrective action must be taken by the owner or operator such as, but not limited to, cover maintenance or repair, or well vacuum adjustments and the location must be remonitored within ten calendar days of a measured exceedance. If the re-monitoring of the location shows a second exceedance, additional corrective action must be taken and the location must be re-monitored again no later than 10 calendar days after the second exceedance. If the re-monitoring shows a third exceedance, the owner or operator must install a new or replacement well as determined to achieve compliance no later than 120 calendar days after detecting the third exceedance, or it is a violation of this subarticle. [17 CCR 95469(a)(1)(A)(B)] Federally Enforceable Through Title V Permit 57.Any closed or inactive MSW landfill, or any closed or inactive areas on an active MSW landfill that has no monitored exceedances of a surface concentration of 500 ppmv as methane, other than non-repeatable, momentary readings and as determined by instantaneous surface monitoring, after four consecutive quarterly monitoring periods may monitor annually. Any exceedances of the 500 ppmv limit as described above detected during the annual monitoring that can not be remediated within 10 calendar days will result in a return to quarterly monitoring of the landfill. Any exceedances of the 500 ppmv limit detected during any compliance inspections will result in a return to quarterly monitoring of the landfill.
