The weather was clear. The <br />ground was mostly snow-covered and muddy. <br />EXCESS SPOIL and DEVELOPMENT WASTE Rule 4.09 <br />Placement; Drainage Control; Surface Stabilization: <br />The slope of the DWDA2 was measured with a Sokkia hand level at what appears to be the steepest part of the pile <br />(near northwest corner); the slope was measured at 40%. This is flatter than the 2H:1V specification in the PAP. <br />Regarding the west end of the DWDA2, where material has been removed in the recent past, the shape of the pile <br />has been graded to closely match the rest of the pile, but additional work is needed to get rid of humps and create <br />slopes less than or equal to 2H:1V. Additional work is also needed at the east end of the pile. <br />The Development Coal Waste Pile appeared to be stable good vegetation and no erosion. <br />The RDA was inspected from below, and a large portion of the RDA was walked. No erosion was seen on the <br />face of the reclamation, and the interface between the reclaimed area and the area above it was separated with a <br />large berm. No erosion or other problems were seen on the upper area (the non-reclaimed area). The side ditches <br />of the reclaimed portion appeared stable, and the sumps above these ditches had a large volume of capacity for <br />sediment. <br />Number of Partial Inspection this Fiscal Year: 4 <br />Number of Complete Inspections this Fiscal Year: 1 <br /> <br />211 <br />Page of <br /> <br /> <br />
