INSPECTION OF ACTIVE AREAS 2-3 . 4 and Sa <br />The Deserado mine has been nearly idle for the entire quarter due to a lay-offofa majority ofthe <br />work force. No refuse was deposited in the refuse pits during the third quarter. <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 rifling <br />in the l00 yr. ditches was repaired on a continuing basis. A minor revision was made to the permit <br />to add rip-rap to the inlet of RP Sa pond, and to both the 100 yr. ditch going into that pond and the <br />undisturbed drainage ditch protecting the RP Sa refuse area. RP 2-3 and RP 4 sediment ponds were <br />cleaned during this quarter. <br />No subdrain system is requved 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 ofsub-area 4. These slopes appeazed stable. Pit 5 consists <br />ofindependent piles ofmaterial with one lift currently being constructed in the northwest area of the <br />pit. The stockpiled material that had been on the lower portion of sub-azea 2-3 has been spread. A <br />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 I ,864,744 tons of refuse have been placed in sub-area 2-3, <br />a total of 1,302,316 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 of4 compaction tests were performed on sub-area 5-a. All of the compaction tests exceeded <br />100 % of Proctor for the refuse material. No other lifts were laid down during quarter. <br />Both the topsoil and subsoil piles for sub-areas 2-3 and 4 have been seeded and are stable. All of <br />
