April 5, 2022 C-1981-035/King Coal Mine JHB (LCC)on the Federal mine permit. One of the sediment traps on the east side of the access had vehicle ruts at the south side. Maintenance of this sediment trap is needed to assure proper function. GCC may need to remind the contractors to pay attention to the sediment control structures. For spring conditions,the sediment control and drainage system was in good condition and functioning as required. The Old Barn area sediment control structures were in place. The silt fencing was well anchored, intact,and functioning well. The contractor has a small pile of road material stored within the sediment control system. No disturbances outside of the approved disturbance area have occurred. The operator needs to assure that the contractor continues to maintain the sediment control system. Grading of the access road at the east SAE area has blocked the ditch to the SAE. GCC need s to assure that runoff from the roadway is able to drain off the road and into the designated sediment control structures.No gullying was occurring on the road or within the sediment control area. We did not drive up the road since the operator was anticipating heavy traffic due to materials delivery. King II area ditches were unobstructed and functioning well. The cattle guard drainage under the haul road was clear and functioning. The silt fencing at the gravel storage SAE on the east side of the haul road has two sections that the silt fencing requires repair. There was no evidence of sediment bypassing the sediment control system. GCC needs to maintain this silt fencing. Culverts throughout the King II facilities area are clear and functioning well. Culvert C19 at the Topsoil Stockpile 92 was not clear. This culvert only functions for access to the topsoil stockpile. Drainage at the Clean Coal stockpile is not impeded by the poor function of this culvert. However, maintenance of all designed culverts and sediment control structures is necessary as regular area maintenance. Pond 1 had good vegetative cover, and was holding a very shallow pool of water by the discharge risers. There was no evidence that any discharge had occurred, and the pool of standing water was well below the discharge elevation. Some trash has blown into the north end of the pond near the dumpsters. Clean up of this windblown trash when conditions allow is needed. Mike informed the inspector that he had collected groundwater samples the third week of March at the MW 1 and MW5 well. GCC needed to use a snow-cat to access the wells and collect the samples. PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface Stabilization;Placement: The operator has placed refuse material on the lower RDA. The RDA was dry at the time of the inspection. Refuse has been laid out in windrows ready to be spread and compacted. The operator has been adding material to the west side of the lower RDA to bring the configuration into agreement with the design. The inspector took measurements of the slope of the lower RDA with a hand held inclinometer. From the east side of the lower RDA to the west side the measurement was 5%(-4 degrees). No gullying was noted on the lower RDA. Runoff appears to be managed appropriately. The road was dry enough to access the upper RDA. The upper RDA was dry and GCC has not been utilizing the upper RDA for new refuse placement yet this Spring. GCC had shaped temporary drainage berms into the surface of the upper RDA. This practice was very effective in directing runoff into the water intercept ditch at the south of the upper RDA. These temporary berms also were effective in directing water away from the road,and eliminated the formation of gullies on the west side of the upper RDA. Drainage from the east end of the upper RDA was Number of Partial Inspection this Fiscal Year: 7 Number of Complete Inspections this Fiscal Year: 3 Page 3 of 6
