Pond D has a trash rack and an oil boom and it was in place. There is a lot of coal fines and sediment at the inlet of the pond. This pond is scheduled to be cleaned on or around 16 July 2007. The operator is first planning on pumping some of the water into Pond B then cleaning out the pond. The wet pond-cleaning material (from both Pond B and Pond D) will be transported to the East Yard Pond until it is dry. Once it is dry it will be hauled to the II West Valley Fill. - Pond E is a concrete dam below the II-West Valley Fill. The pond was dry at the time of the inspection.

There was no settling or cracking at the location of the backfilled portal or the bench where the portal was located. The reclaimed area was well vegetated with a few weeds. 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. 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 and all of refuse has been spread and compacted on the pile. 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 pile's outslopes at the time of the inspection. -The II-West refuse pile has the beginning of the first lift placed on it. There were eight piles of refuse on the pile waiting to be spread and compacted at the time of the inspection. The pile appeared to be well compacted and there was no water pooling on the pile at the time of the inspection. This pile will be used in the summer months due to the steepness of the haul road. 0-
