Guam EPATitle V Federal Operating PermitLayon Municipal Solid Waste Landfill, lnamjan, GuamPermit No. FO-OOSn.B.3 The permittee shall design the landfill gas collection system to achieve a captureefficiency of 90% of all landfill gas generated at the site. [GAPCSR Section1104.12(1)]n.B.4 The permittee shall route all collected landfill gas to an open flare designed andoperated in accordance with 40 CFR §60.18 and 40 CFR §63.11. [40 CFR§60.752(b)(2)(iii),40 CFR §60.18(c) through (f), 40 CFR §63.II(b)]n.B.5 The particulate emissions from this unit shall not exceed 0.40 Ib/MMBtu. [GuamState Implementation Plan (SIP), Section 7.5]II.B.6 The permittee shall not cause or permit the continuous emission of visible airpollutants with a density equal to or darker than twenty (20) percent opacity fromany emission unit nor the emission of visible air pollutants of a density darkerthan sixty (60) percent opacity for a period aggregating more than tlu'ee (3)minutes in any sixty (60) minute period. [GAPCSR, Section 1103.3; SIP, Section10.1]II.C.Operational Standards for Collection and Control Systemsn.C.l The Permittee shall operate the collection system with negative pressure at eachwellhead except under the following conditions: [40 CFR §60.753(b)]a. A fire or increased well temperature. The Permittee shall record instanceswhen positive pressure occurs in efforts to avoid a fire. These records shall besubmitted with the annual reports as provided in 40 CFR §60.757(f)(1);b. Use of a geomembrane or synthetic cover. The Permittee shall developacceptable pressure limits in the design plan; orc. A decommissioned well. A well may experience a static positive pressure aftershut down to accommodate for declining flows. All design changes shall beapproved by USEPA and GEPA.II.C.2 The Permittee shall operate each interior wellhead in the collection system with alandfill gas temperature less than 55°C and with either a nitrogen level less than20 percent or an oxygen level less than 5 percent. The Permittee may establish ahigher operating temperature, nitrogen, or oxygen value at a particular well. Ahigher operating value demonstration shall show supporting data that the elevatedparameter does not cause fires or significantly inhibit anaerobic decomposition bykilling methanogens. [40 CFR §60.753(c)]ILC.3 The nitrogen level shall be determined using Method 3C. [40 CFR §60.753(c)(I)]n.c.4 The oxygen level shall be determined by an oxygen meter using Method 3Aexcept that:80f39
