Elk Creek C-1981-022 21 August 2007 ~~ P9 2/2 Hydrologic Balance (cont.): - Pond E is a concrete dam below the II-West Valley Fill. The pond was dry at the time of the inspection. The concrete dam appeared to be stable. - The ditches along the haul road to the Elk Creek facilities area were all cleaned and appeared to be stable and functioning as designed. All of the sumps in the ditches were also clear. No erosional problems were noted in any of the ditches. After the weekend rains, there were a few straw bales that were blown-out. These straw-bales need to be fixed and/or replaced as necessary. Explosives: -The explosives magazines were in place just below Pond O and the elevated conveyor from Elk Creek portals to the coal stockpile at the time of the inspection. The small pad where the magazines are located was stable and in good condition at the time of the inspection. Processing Waste: -The West Valley Fill was well maintained and stable at the time of the inspection. There was no water pooling on the pile. There were several piles of sediment from the pond cleanings (that was dry enough to haul directly to the pile) that need to be spread and compacted. There is approximately 10 vertical feet left on the pile, based on the operator's recent survey and the survey stakes that have been placed in the ground. The operator plans to use the West Valley Fill during the winter months and the II-West refuse pile during the summer months. This will extend the life of the West Valley Fill. The reclaimed outslopes of the pile were all well vegetated and stable. No erosional problems were noted on the outslopes at the time of the inspection. - The II-West refuse pile has the beginning of the first lift placed on it. There were approximately 20 piles of refuse on the pile that need to be spread and compacted. The remaining areas of the pile appeared to be well compacted and stable and there was no water pooling on the pile at the time of the inspection. Support Facilities: -Both the Sanborn Creek and Elk Creek Mine facilities areas appeared to he stable at the time of the inspection. No erosional or other problems were noted at either of the facilities areas. - The downhill conveyor from the Elk Creek Portals to the coal stockpile was stable and in good condition at the time of the inspection. Topsoil: -The Elk Creek topsoil pile was well vegetated and appeared to be stable at the time of the inspection. No erosional problems were noted. Revegetation/Reclamation Success: -The East Yard refuse pile reclamation remains stable. The vegetation is in good shape and there are no signs of erosional problems on the outslopes of the pile.. Air Resource Protection: -There were no problems with fugitive dust on any of the haul roads or from the coal stockpile at the time of the inspection.
