Elk Creek C-1981-022 18 October 2007 ~~ P9 2/3 Hydrologic Balance (cont.(: -The East Yard Pond still contains a large amount of material placed there from the pond cleaning (approximately half of the pond area is covered to a depth of approximately two feet(. This material needs to be removed from the pond and hauled to the West Valley fill as soon as it is dry. The pond contained a small amount of water from the runoff from the recent precipitation event but was not discharging. The pond appeared to 6e stable at the time of the inspection. - The ditches along the haul road to the Elk Creek facilities area appeared to be stable and functioning as designed. Some of the ditches and sumps do need to be cleaned as a result of the recent storms. No erosional problems were noted in any of the ditches. Explosives: -The explosives magazines were in place just below Pond D 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. No erosional problems were noted on the explosives magazine pad 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. The operator has excavated approximately five feet of material from approximately one half of the pile. This is the material that was hauled to the pile from the pond cleanings. The material did not meet compaction limits and has to be respread and compacted. OMLLC is reminded that the maximum lift height for spreading and compacting is two feet. 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. There was also a stockpile of large black pipe (possible for use underground) on the pile at the time of the inspection. 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 was inaccessible at the time of the inspection due to the wet and muddy conditions. Support Facilities: -Both the Sanborn Creek and Elk Creek Mine facilities areas were wet and muddy but appeared to be 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 goad condition at the time of the inspection. - The Sanborn Creek Mine fan remains in place along old Highway 133. The pad and the fan were wet but appeared to be stable at the time of the inspection. No erosional problems were noted on the pad at the time of the inspection. - The pad for Substation #3 (along old Highway 133) was wet at the time of the inspection. The pad remains stable and no erosional problems were noted on the pad at the time of the inspection. Four deer were grazing on the slope above the suhstation. - The corridor for the Sanborn Creek Mine overland conveyor, which was reclaimed several years ago, remains stable, with no erosional problems noted.
