April26, 2011 C-1981-010/Trapper Mine RDZ <br /> Discharge from all ponds was clear. No serious problems were identified with any of the ponds,but some <br /> maintenance items were identified during the inspection.The flumes at Oak Gulch#2 and East Middle Flume#1 <br /> require maintenance,as has been noted in prior inspection reports.Due to high water levels, it was difficult to <br /> determine the level of sediment in the ponds or if sediment markers are in place. <br /> Within two observed channels banks have been significantly eroded and require maintenance: the channel <br /> downstream of East Pyeatt#3 pond and the channel downstream of culvert AE10. <br /> Per Graham Roberts, a significant amount of water has been pumped out of K Strike Pit this spring. <br /> GENERAL MINE PLAN COMPLANCE: <br /> At the K Strike Pit,the Molly Brown dragline was idle during the inspection of April 27,2011. A Caterpillar 5130 <br /> excavator was loading coal into trucks. <br /> During the inspection of April 27th,the Baby Doe dragline was walking within the F Pit and the Queen Anne was <br /> idle. <br /> The mine was found to be in general compliance with the permit. <br /> ROADS—Rule 4.03: <br /> Many roads were observed during the inspection,including the Life of Mine Road,the North A Road,the Middle <br /> Ash Road,the Middle Z Road,the K1 Road,the Z3 Road,and the B/C Haul Road. All active haul roads were <br /> stable and were functioning as permitted at the time of the inspection. North A Road was extremely muddy and <br /> contained deep ruts. <br /> Several ditch-outs were inspected along the Life-of-Mine Road,and no significant erosion or other problems were <br /> observed. <br /> RECLAMATION SUCCESS -Rule 4.15,Rule 3: <br /> Due to snow conditions,the ground was not visible at many locations during the inspection. On the areas that <br /> were visible,no problems such as gullies on reclaimed areas were observed. Rills were observed on the reclaimed <br /> slope north of the Ash Pit,and these appear to be larger than they were in March. Continued monitoring is <br /> advised. <br /> Area A-C-05 (in SL-12 application)was inspected and no erosion or large bare areas were detected. <br /> Number of Partial Inspection this Fiscal Year: 8 <br /> Number of Complete Inspections this Fiscal Year: 4 <br /> Page 3 of 10 <br />
