INSPECTION REPORT Site: National King Coal Mine, Hesperus, Colorado Inspected sy: Dan R. May, P.E., Project Engineer Inspection Gate: (quarterly Inspection, November 9, 2flfl3 ;>. ;. Ponds: The east and west sedimentation ponds and their embankments and outlets appear in good condition. Tha west pond is shown in photograph 1 and the east in photo 2. Both ponds are in need of routine cleaning. Tha outlet works are clean and operable. Drainage ditches: The east side and west side drainage channels appear in good general condition. The coal storage pile, in the yard, continues to be very larger and is encroaching On fhe clean water ditch on the east side- The ditch which runs behind the office and discharges into Hay Gulch, Photo 3 is in good condition. Tha upper yard is shown in photos d and 5 and is in good shape. The upper yard is largely covered by the storage pile. All drainage grates, pipes and ditches were c{ear at the time of #his inspection. All other ditches and drainage structures were inspected and appear in good operating condition. There are no apparent drainage problems on the site. AN drainage features have been constructed and are operating as stated in the drainage plan submitted to the Division of Minerals and Geology. Coal Waste Pile: There are no visible signs of structural instability on the waste pile. Because the storage pile has intruded onto the knver half of the front face Of the waste pile special care should be used when this opal is removed. The first concern is [flat the compacted fdl that forms this face is not significantly disturbed. Design slope angle and Compaction requirements must be maintained on This face. Secondly, it is likely that the established vegetation on the covered portion Of the face will die or be scraped off during this period. This area should be revegetaiad in accordance with the approved mine plan. The top of the waste pile is in good condition but the is not at the design slope. It currently undulates with many tow areas that will Eorm ponds. This area should be graded with a 1 °h-2°f° cross slope to a weN formed ditch on the east side. The upstream end of the water pile underdrain was located and the drain was extended upvalley. Photo 6 shows a portion of the excavation and drain fill material. Except for the items mentioned above the fill on the waste pile has been constructed as specified in the design approved by the Division of Minerals and Geology.
