01 closure, temporary jumpers will be installed outside the closure area to <br /> maintain vacuum to the field. <br /> 3.9 LANDFILL GAS MONITORING SYSTEM <br /> 27 CCR, Section 20925 requires that subsurface gas monitoring wells <br /> (probes) be installed as part of closure around the perimeter of the landfill <br /> within the property limits but outside the limits of refuse with a spacing of <br /> approximately 1,000 feet. As discussed in Section 2.1, a landfill gas <br /> migration monitoring system is in place at the Forward Landfill and probes <br /> SGP-7A, SGP-8A, SGP-9A, SGP-1013, SGP-14, and SGP-13 are located <br /> near the perimeter of the Stage IA partial closure area as shown on Drawing <br /> Sheet 2. As part of closure, the existing probes will be protected in place. <br /> 3.10 GROUNDWATER/SURFACE WATER MONITORING SYSTEM <br /> Groundwater monitoring programs are currently being implemented on a <br /> quarterly basis at the Forward Landfill, as discussed in Section 2.2. Figure 4 <br /> shows the location of the existing groundwater monitoring wells. No <br /> modifications to the groundwater/surface water monitoring system are <br /> required as part of the Stage IA partial closure. <br /> 3.11 SITE SECURITY <br /> The Forward Landfill is currently equipped with a perimeter fence, gates, <br /> locks and signs. The fencing and locked gates restrict access by persons <br /> and vehicles other than those authorized. <br /> 3.12 STRUCTURE REMOVAL/DECOMMISSIONING OF ENVIRONMENTAL <br /> CONTROL SYSTEMS <br /> At this time, there are no plans to decommission any structures or <br /> environmental control systems at the Forward Landfill during the closure of <br /> Stage IA. If deemed necessary, any decommissioning of boreholes, <br /> monitoring wells or peizometers will be conducted in accordance with the <br /> appropriate regulatory agency requirements (including notifications, as <br /> required) and in general accordance with post-closure maintenance plan <br /> procedures. <br /> Forward Landfill PFCPCMP 3-16 <br /> Z:\PROJECTSWIIied Waste\Forward\Reference Files Prior JTDWune 05 Stage IA Partial FCPCMP\FL-sec3.doc:6/16/2008 <br />
