Processing Waste The faces of the Refuse Pile Expansion pile and the Lower Refuse Pile showed no evidence of structural instability. Survey markers were in place on the faces of both piles. The slope faces were grass-covered. The top of the Lower Pile is being used for equipment storage, as approved. Support Facilities No problems were found in the following areas: materials storage bench, trash compactor, explosives storage area, barrel storage building, hydraulic components storage, the Sylvester Gulch mine water pumping facility, and the polishing pond. Topsoil Grass cover appeared adequate for controlling erosion on the following stockpiles: Main Topsoil Stockpile, Sylvester Gulch Subsoil, Topsoil Piles#1 and#3 in Sylvester Gulch, the Sylvester Gulch Shaft Site stockpile, and the Deer Creek Shaft stockpile. General Mine Plan Compliance The operator appeared to be following the approved mine plan. Slides and Damage A rock slide recently occurred in Sylvester Gulch where longwall mining is occurring in Panel 25. The slide is in an area designated as having high rock fall potential on map 53b. Offsite Support Facilities Topsoil stockpile markers and sediment control measures were in place in the Corrals laydown/staging area, Deer Creek Shaft, and the borrow area for the Monument Dam work. A mine W. sign was properly displayed.on the Forest Service road at the Corrals laydown/staging area. There was no activity at the Deer Creek Shaft where the vent shaft and emergency escape shaft are being raised-bore drilled.
