Ground water elevations will continue to be measured at the established <br /> piezometers quarterly starting at the time of permit approval from the DRMS. This <br /> will further confirm seasonal water surface elevations for the site prior to mining. In <br /> addition, just prior to beginning Compacted Clay and drain installation, an additional <br /> measurement at each well will be completed. Measurements will be provided to the <br /> RMS as part of an annual report. <br /> Step 2 - Monitoring <br /> Following compacted Clay Liner and drain installation and through mining, <br /> piezometers will continue to be measured quarterly with measurements provided to <br /> the DRMS as part of the annual report. <br /> Step 3 - Mitigation Triggers <br /> A ground water modeling study was prepared for the proposed operation to <br /> include estimated effects as a result of Groundwater Barrier and drain installation. <br /> The anticipated effects modeled at the locations of the proposed piezometers are as <br /> follow.. <br /> Piezometer Predicted Change in Water Elevation (Feet) <br /> 1 0 <br /> 2 -0.5 <br /> 3 0 <br /> 4 0 <br /> 5 0 <br /> 6 3.0 <br /> 7 0 <br />
