The surface drainage facilities were adequately <br />maintained and were working properly. No subdrain system is <br />regLlired by our permi*_, since geotechnical ins*estigatior. fcr the <br />disposal site revealed no ground water present. Permanent out <br />slopes are approximately one-third complete on the toe of sub-area <br />2-3. These out slopes are stable. A groundwater monitoring well <br />has been installed between sub-area 1 and sub area 2-3. To date no <br />water has accumulated in the well. <br />Sub-area 1 has been reclaimed and is no longer in use. To date, a <br />total of 1,342,226 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 178,352 tons <br />of refuse have been placed to date. <br />Daeredo Mine <br />P.O.
