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 /> <br />Piezometer <br />1 <br />2 <br />3 <br />4 <br />5 <br />6 <br />7 <br /> <br />Predicted Change in Water Elevation (Feet) <br />0 <br />-0.5 <br />0 <br />0 <br />0 <br />3.0 <br />0
