March 7,2013 C-1980-007/West Elk Mine JRS HYDROLOGIC BALANCE(cont.) -The ditches along the Sylvester Gulch haul road were covered with some snow but a large amount of water was flowing in the ditches. There was some water flowing along the outer edge of the road but it was snow melt from the road itself and not water flowing out of the pond. There was a large portion of the ditch where the check dams have been damaged(due to a blade in the ditch in an attempt to clean it). These will need to be repaired as soon as practical. West Elk may want to consider redesigning these check dams, as there appear to be more than are actually necessary. Overall the ditch was functioning properly at the time of the inspection. -The ditch around the LRP was flowing at the time of the inspection. There was some sediment in the ditch but there were no blockages seen. -The ditches around the RPE were all flowing at the time of the inspection. There was some sediment in the ditch but it was not impeding flow. There was some minor rilling in spots where water was flowing into the ditch and some minor rilling in the ditch itself. The ditch will need to be monitored and cleaned and repaired when conditions allow. West Elk has placed some new straw bales in the ditch at the point just above the road spur to the RPE and RPEE. -The half-culvert from the RPEE ditch did not appear to have any water running in it at the time of the inspection. The RPEE was inaccessible so the ditch was not inspected. GENERAL MINE PLAN COMPLANCE: -West Elk was currently mining in the E-Seam in longwall panel E4. They were currently mining just past cross- cut 56 at station 105+20. -West Elk was working on development of the longwall panel E5 headgate. They were almost to cross-cut 52 at station 97+60. There was no change in the development in the longwall panel E6 headgate or in the E South Mains since last inspection. -Based on the MSHA map in the operations area in the basement of the main office building,mining appears to be progressing as permitted and shown on approved permit Map 51 -E-Seam Projected Operations. PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface Stabilization; Placement: -The RPEE was inaccessible at the time of the inspection due to road conditions. -The RPE was also inaccessible at the time of the inspection as operator was removing snow from the pile. The reclaimed slopes of the pile were inspected from below,by the RPE pond. The reclaimed slopes were well vegetated and stable and no erosional problems were noted. There was a slide on the east side of the pile and refuse material flowed down the outslope of the pile. The material was cleaned up and the pile was regraded. There is still some work that will need to be completed once conditions allow. -The LRP remained stable at the time of the inspection. The slopes are all well vegetated and no erosional problems were noted. ROADS—Rule 4.03 Construction 4.03.1(3)/4.03.2(3)Drainage 4.03.1(4)/4.03.2(4) Surfacing and Maintenance4.03.1(5) and(6)/4.03.2(5) and(6)Reclamation 4.03.1(7)/4.03.2(7): -The main haul road is a paved road.
