May 29, 2014 C- 1980- 007/West Elk Mine ZTT <br />Clean water diversion ditch was inspected along the upper facility bench that includes Shaft 42 below the north <br />facing slope. The ditch was stable and no cutting or erosional issues were observed. However, at the southwestern <br />point of the upper facility bench, the clean water is diverted by a culvert. The culvert was partially filled inside the <br />culvert with sediment and was in need of general maintenance. Correspondence from West Elk representatives <br />noted that this maintenance item has already been addressed. No issues remain. <br />Shaft 41 and shaft 42 pads were in good condition. Pads were graveled for erosion control and sloped to perimeter <br />ditches to direct runoff to the associated sediment pond. Gravel pads showed no signs of erosion or ponding. No <br />issues were observed. <br />Concrete sumps along the coal stockpiles were inspected. Sumps are cleaned approximately every month on an as- <br />needed- basis. Sediment and coal fine build up was at a minimum with no issues observed. <br />Sediment Pond MB -5E held water with no discharge. Pond embankments were stable and vegetated. Emergency <br />spillways for both ponds were armored with rip rap. Spillways discharge into a large armored channel before <br />reaching the river in the event of pond discharge. No issues were observed at pond MB -5E. <br />GENERAL MINE PLAN COMPLIANCE: <br />General spring maintenance from snow melt and seasonal weather is ongoing at the mine site.
