May 22, 2014 C- 1982 - 056 /Foidel Creek Mine JDM <br />RDA-4 <br />The underdrain of the RDA Expansion and a portion of the runoff of the RDA area reports to the Area 1 Pit, which <br />is a remnant of the Eckman Mine Complex surface mine pit. The Area 1 Pit is a totally incised excavation <br />enclosed by natural ground and backfilled surface mine spoils. In addition to receiving a minimal portion of the <br />water from the RDA, the Area 1 Pit is used for temporary storage of excess mine water as part of the mine water <br />recycle and dewatering system. The Area 1 Pit was stable at the time of the inspection and no problems were <br />noted, with the exception of the following: <br />- Non -coal waste in the form of wooden blocks was observed throughout the edges of the Area 1 Pit. All non - <br />coal waste should be disposed of appropriately to ensure function of the Area 1 Pit discharge to Sedimentation <br />Pond D. <br />- Two unidentified —4" diameter pipes were observed from the Area 1 Pit, under the access road, and to the Pond <br />D embankment were observed. These pipes were not functioning at the time of the inspection with one housing <br />electrical cable stockpiled on the Pond D embankment and the other empty. If these pipes are required, <br />identification on appropriate maps is needed. If not required all non -coal waste will need to be disposed of. <br />1 <br />Stockpiled Refuse with Area 1 Pit and Pond D Area 1 Pit <br />Number of Partial Inspection this Fiscal Year: 10 <br />Number of Complete Inspections this Fiscal Year: 3 <br />Page 3 of 7 <br />
