As can be seen the highest anticipated change occurs in piezometer 6 in the <br /> south east corner of the proposed mining operation and most near the Swartz <br /> residence. Despite this change, the ground water surface is anticipated to stay <br /> well below (approximately 11 feet) the basement floor elevation of the home <br /> following drain and Compacted Clay Liner construction. <br /> If a change in groundwater elevation greater than two feet beyond the seasonal <br /> baseline plus the anticipated (modeled) change in ground water elevations <br /> occurs, then an intermediate second measurement will be taken 45 days after <br /> the initial reading. If the reading is still outside the mitigation trigger and an <br /> impact is imminent (i.e. a flooded basement or field), mitigation will be performed. <br /> Step 4 - Mitigation Alternatives <br /> Mitigations to a raised or lowered water table will be completed by the City under <br /> the following conditions. <br /> 1. Monitoring data demonstrates that a change in ground water surface <br /> elevation has occurred beyond that anticipated through Compacted Clay <br /> Liner and drain installation and as a result of seasonal variation. <br /> 2. The change in ground water elevation has caused an impact to adjacent <br /> water supply, an impact is imminent, or has caused an impact to <br /> basement or field as a result of high groundwater elevation. <br /> Lowering of water table <br /> If mitigation from a lowered water table is required, one of the two following <br /> actions will be completed by the City. <br /> 1. Alternative 1 - The City will provide the well owner with water, until the <br /> water level returns to normal. <br /> 2. Alternative 2 - The City will drill the affected party's well deeper to restore <br /> well production to pre project conditions. <br /> Raising of Water Table <br /> If mitigation to lower the water table is required, one of the two following actions <br /> will be completed by the City. <br /> �. Alternative 1 - A well and pump will be installed and operated to locally <br /> reduce the water elevations in the aquifer. <br /> 2. Alternative 2 - An additional subsurface drain may be installed to reduce the <br /> water surface elevations in the vicinity of the impacted structure or field. <br /> Commitment <br /> Operator shall commit to the mitigation measures above regardless of whether <br /> the mitigation triggers are the result of installing a clay liner on Reservoir#2 or <br /> Reservoir #4 <br />
