P.E., Project Engineer ~; ~„~:., , ._ ._ai,~r` Inspection Date: Quarterly Inspection, July, 2005 ee~dsF Ponds: The inlets, outlets and embankments of both ponds were inspected and appear in good condition. As seen in photo 1, the west pond is being cleaned of sediment. The pond volume is significantly increased. Excess material is being placed orr the waste pile. Drainage Ditches: The drainage channels, on the north and south sides of the waste rock pile, appear in good general condition. Care should be taken to maintain the stretch of Gean water ditch between'the southwest comer of the waste pile and the mine office. The upper and lower yards are all in good shape as seen in photo 2. The culvert entrance located on the major drainage that enters at the south side of the mine site near the adit is in danger of being blocked by vegetation, photo 3. All other ditches and drainage structures were inspected and appear in good operating condition. Except where noted, all drainage features have been constructed and are operating as stated in the drainage plan submitted to the Division of Minerals and Geology. Coal Waste Pile: As mentioned in previous inspection reports, over-steepening of the waste pile face at the toe of the slope still exists. This is shown on photo 4. At this time there are no visible signs of structural instability on the waste pile but a fix for this problems should be pursued. Photo 5 shows the top of the waste pile as it undergoes reconstruction. As mentioned in previous reports, the top of the pile and the drainage ditch was rough and not at the required design grades. Since the last inspections the top of the pile has been :.omplete{y regarded. Although this work was stilt in progress at the time of this inspection, it looks much better and appears that it will meet the design requirements when completed. Except for the items mentioned above the frl{ on the waste pile has been constructed as specified in the design approved by the Division of Minerals and Geology.
