The groundwater, surface water, and vadose zone monitoring points are shown on Figure <br /> 2. The WQPS will also apply to future monitoring points, which are established during <br /> facility development. <br /> 4.4 Point of Compliance <br /> 4.4.1 Groundwater <br /> The groundwater Point of Compliance is typically the vertical surface along the <br /> hydraulically down gradient boundary of the WMU that extends through the uppermost <br /> aquifer of the underlying unit. Since it is infeasible to install a Point of Compliance well <br /> on the southern boundary of LF-1 as discussed above, some of LF-1's Point of <br /> Compliance wells are down gradient of LF-2. The Point of Compliance wells for LF-1 <br /> are MW-3, MW-5 and MW-6. The Point of Compliance wells for LF-2 are MW-2R, <br /> MW-5 and MW-6. <br /> 4.4.2 Surface Water <br /> The surface water Point of Compliance is SW-2 for both LF-1 and LF-2. <br /> 4.4.3 Vadose Zone <br /> The vadose zone pore fluid Point of Compliance lysimeters are LZ-2, LZ-3, LZ-4, LZ-5, <br /> and pan lysimeters under LF-2. The vadose zone gas Point of Compliance probes for <br /> both LF-1 and LF-2 consists of 25 tri-level perimeter soil gas probes SG-12 and SG-102 <br /> through SG-125. In addition, Point of Compliance soil gas probes SG-1, SG-2A, SG-3A, <br /> SG-4, SG-5, SG-6A, SG-7, SG-9, SG-10A, and SG-11A are situated around the <br /> perimeter of LF-1. <br /> 4.5 Compliance Period <br /> The compliance period for LF-1 and LF-2 is the number of years equal to the active life <br /> of the units (including any waste management activity prior to the adoption of the WDR) <br /> plus the closure period. The compliance period is the minimum period of time during <br /> which a water quality monitoring program will be conducted subsequent to a release from <br /> the unit. <br /> Foothill WQPS Rev Ldoc <br /> 4-7 <br />
