No subdrain <br />system is required by our permit, since geotechnical investigation <br />for the disposal site revealed no ground water present. Permanent <br />out slopes have been started on the toe of sub-area 2-3. These out <br />slopes are stable. A groundwater monitoring well has been <br />installed between sub-area 1 and sub area 2-3. To date no water <br />has accumulated in the well. <br />Sub-area 1 has been reclaimed and is no longer in use. To date, a <br />total of 1,296,978 tons of refuse have been placed in sub-area 2-3. <br />Construction of sub-area 4 has been completed. Lifts are being <br />placed at the north end of sub-area 4 and a total of 114,077 tons <br />of refuse have been placed to date. <br />Deserzdo Mine <br />P.O.
