<br />INSPECTION OF ACTIVE AREAS 2-3 . 4 and Sa <br />The Deserado mine's preparation plant has been nearly idle for the entire quarter due to a new focus <br />of by-passing a majority of the mined coal rather than washing it. Consequently, relatively little <br />tonnage was placed in the refuse disposal areas. <br />There are no apparent points of seepage, or indications of slope failure on the active piles. <br />The surface drainage facilities were adequately maintained and were working properly. Minor tilling <br />in the 100 yr. ditches was repaired on a continuing basis. <br />No subdrain system is required by our permit, as geotechnical investigations for the disposal site <br />revealed no ground water present. <br />Permanent out slope remain at approximately 80% complete on the toe of sub-area 2-3 and <br />approximately 50% complete on the toe of sub-area 4. These slopes appeared stable. Pit 5 is <br />currently being covered by thin lifts. The spreading and compaction of the waste is currently running <br />concurrent with its delivery. <br />A groundwater monitoring well had been drilled between sub-areas 1 and 2-3. To date no water has <br />accumulated in the well. <br />At the end of the fourth quarter a total of 1,879,469 tons of refuse have been placed in sub-area 2-3, <br />a total of 1,333,025 tons of refuse have been placed on sub-area 4, and a total of 215,024 tons of <br />refuse have been placed in sub-area Sa. <br />A total of four compaction tests were performed on sub-area 5-a, and one compaction test was done <br />on sub-area 4. Further compaction testing for sub-area 4 was hampered by hard frozen ground. All <br />ofthe compaction tests exceeded 90 % of Proctor for the refuse material. No refuse was spread or <br />compacted on sub-area 2-3 during the quarter. <br />
