November 4,2021 C-1981-035/King Coal Mine JHB The West pond was partially cleaned of sediment until the pond became too wet to complete the clean out. GCC is allowing the sediment to dry some more, and anticipates they may be able to continue the sediment clean out. As such,the berm has not been completely re-established to allow equipment access for sediment clean out. The West pond does have sediment storage capacity,but GCC hopes to clean it further. Collection ditches at King I were in good repair and functional. The SAE's on the West and East sides of the haul road into King I were in adequate condition. The West side SAE would benefit from clean out of the sediment prior to the winter months. Old Barn Area: The silt fence at the old barn area is holding up well. A small pool of water is held upslope of the hay bales in the drainage point of the silt fencing near the barn. The silt fencing remains properly keyed in with no bypassing of the sediment control structures onto the county road. Drainage of the access road is directed appropriately. Wade reported that the contractor grades the roadway regularly. Water bars get graded out,but the road is compacted well enough that no gullies are forming. Cuts in the roadside berms need to be maintained as some of them are blocked from the road grading. By keeping the drainage cuts functional,this will reduce the volume of flow at the base of the roadway. Sediment and runoff management at the Old Barn area appears to be adequately controlled. King II: The sediment Pond at King II was damp but not holding a pool of water. The embankments are well vegetated and not weedy. Wade mentioned that GCC hopes to clean sediment out of this pond as conditions allow. Sediment storage capacity is still adequate for Pond 1,but clean out is part of the operator's regular maintenance of the pond. The haul road SAE/Gravel storage area Silt fence is holding up well and appropriately keyed in. The cattle guard SAE was cleaned out and appeared to contain adequate storage capacity prior to the winter months. Ditches throughout the King II facilities area were clear of debris and in good condition. Culverts at the warehouse/maintenance area CI &CI were clear and flowing unimpeded. PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface Stabilization;Placement: The operator was not hauling refuse to the RDA at the time of the inspection. GCC had been placing material on the lower refuse area earlier this fall. The lower RDA is sloped to the west. This appears to concentrate the runoff to the curve just south of where the haul road adjoins the lower RDA. This has resulted in gullying on the side of the RDA to Reach 10 ditch(west of the bathhouse). All refuse material that came off the lower RDA bench was contained in the ditch. Cleaning material out of the ditch and building up the outside of the ditch will assure that runoff is able to be contained in the ditch and flow towards the West Pond. GCC needs to place and grade the refuse material on the lower RDA to the design specifications in Appendix 10(4A). This will minimize the runoff velocity off the top of the pile. Page 16 of Appendix 10(4A)describes the management of the surface grading. The RDA needs to keep the lower RDA bench in compliance with with this design. The haul road to the upper RDA was in good condition. GCC has not been hauling material to the upper RDA this Number of Partial Inspection this Fiscal Year: 2 Number of Complete Inspections this Fiscal Year: 2 Page 3 of 8
