Operate the collection and control system with a negative pressure at each well head of up to 5 inches of water column in areas that have a geomembrane or synthetic cover. [40 CFR§60.753(b)(2)] iii. If the collection of landfill gas from the leachate system using leachate risers and leachate sump extraction is from an area or cell in which the initial solid waste has been in place for a period of five years or more(if active),or two years or more(if closed or at final grade),the temperature,pressure, nitrogen and/or oxygen shall not exceed the limits of Subpart WWW,except the oxygen limit shall be less than or equal to 23 percent,as long as subsurface oxidation and the killing of the methanogens does not occur. iv. When applicable, the Permittee may use an EPA approved on-site multi-gas analyzer, in lieu of a laboratory method,for determining the oxygen content of the landfill gas at each well and monitoring point. v. The Permittee shall exclude dangerous areas such as roads, the active area,traffic areas and slopes steeper than 4:1 from surface emissions monitoring requirements. In addition,the Permittee shall temporarily exclude areas with ongoing construction or reconstruction of the gas collection system from the surface scans,until such time as the collection system is completed and for functional. The Permittee is required to make visual inspections of the areas to detect elevated concentrations of methane which results in distressed vegetation,cracks and seeps in the covers. Permit No.08849T07 Page 10 vi. The Permittce may exclude the monthly readings(pressure,temperature,nitrogen or oxygen content)at a raised vertical well(prior to final grade)in active areas of the landfill as long as the welt cannot be safely reached by a technician. if the facility cannot bring the waste height up to the new grade and reattach the well within a reasonable lime(four months),then modifications to the lateral/welthead would have to be made including lowering the well and reattaching the wellhead to begin the required monitoring. vii. In accordance with 40 CFR§60.755(a)(3)and§60.755(a)(5)"Compliance Provisions",owner or operator shall take corrective action to remedy gas collection and control system operating and compliance monitoring excecdances within 5 calendar days. If the condition cannot be corrected within 15 days of the initial exceedance,the GCCS must be expanded within 120 days of the initial reported exceedance,or an alternate remedy to correct(lie exceedance(s). Any timeline extending more than 120 days shall be approved by the Washington Regional Office. viii.If gas collection and control system does not contain any bypasses of the flare,the requirement to record flow or bypass of the flare is not applicable. ix. Wells that experience positive pressure after being shutdown to accommodate declining landfill gas flow rates can be decommissioned if permission is granted by the Administrator. As an alternative to decommissioning wells under the provisions,the following changes to its standard operating procedure for wells where persistent oxygen execedances are not the result of operations and/or maintenance issues: (A) Wells where oxygen concentrations do not decline to acceptable levels after more than one hour of reduced vacuum will be shut off until the gas quality recovers. (B) The monthly monitoring required by 40 CFR Sec.60.755 will be conducted for wells that have been shutdown,but positive pressure or elevated oxygen concentrations will not be considered excecdances of the operating limits in 40 CFR Sec.60.753. (C) IF monthly monitoring indicates that pressure has built up in the well and the oxygen concentration still exceeds five percent, the well will be opened to relieve the pressure and will be shutdown until it is monitored the following month. (D) If the monthly monitoring indicates that gas quality has improved(i.e.,the oxygen concentration has dropped below five percent), the well will be brought back on line until the gas quality declines again. (E) The quarterly methane surface concentration monitoring required under 40 CFR Sec.60.755 will be conducted for wells that have been shutdown. Standard remediation steps,including evaluating the need to return wells to full-time service,will be followed if execedances of the 500 ppm methane surface concentration limit are detected. The Permittce shall update the facility diagrams to indicate which wells are shutdown because the landfill gas production rates are too low to per►nit continuous extraction. x. The Permittee may its USEPA Method 3C or ASTM D3588 in place of Method 18 and ASTM D1946 to determine landfill gas components for calculating net heating value under 60.18(c)(3). j.
