November 8, 2022 C-1981-035/King Coal Mine JHB facilities area. The ditches throughout King I facilities had held up well. GCC has pulled refuse material away from the Clean water ditch at the northeast extent of the lower RDA. This action satisfies the Division's immediate concerns. Continued attention must be paid to management of this area and communication with the equipment operators on the lower RDA needs to be clear to minimize encroachment of waste into this ditch. The county road construction workers continue to store material at the entrance road to King L Silt fence has been installed on the east side of the entry on the east side of the road base and gravel piles.This is encouraging and no sediment from these piles appeared to have ventured off site to the east. This third party continues to allow employees to park personal vehicles and equipment on the entry road. It appears they are improving on not parking in the sediment traps. However,gravel has been pushed into the wattles on the west side of the entrance road. GCC needs to assure that the alternate sediment control structures are repaired,maintained,and kept functioning to avoid off site impacts. The rancher on the property to the east of the entrance road has set up a corral next to the King I road. It appears that loading or unloading activities may be conducted from the access road. GCC needs to assure that sediment control structures are maintained with this activity. Old Barn Area: Considerable sediment came down the road and was captured by the silt fencing and sediment traps. GCC needs to clean these structures out, and reset the silt fence to assure that the alternative sediment control structure function as designed. The road crew continues to use portions of this area for material and equipment storage. Sediment pond 1 at King II facilities was holding a shallow pool of water well below the discharge elevation. Embankments were well vegetated. No problems were noted with this pond. Ditches and culverts were maintained at the King II facilities area. Some gravel at the material storage site on the south side of the haul road coming into the facilities has been pushed close to the silt fence at this alternate sediment control site. GCC needs to assure the function of the silt fencing remains intact. PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface Stabilization;Placement: The upper RDA has not had any new refuse placed on it since the previous inspection. The operator has graded out the temporary water bars on the top of the upper RDA. These features were temporary unrequired features to help manage runoff. The north and east portions of the upper RDA are maintaining the designed grade. However,the southwestern portion of the upper RDA has a slope greater than the design. GCC needs to continue to shape the pile so the slope does not exceed that in the plan. Maintaining the correct slope will improve the runoff management as well. There has been some down cutting of the interface between the upper RDA and the native slop on the south of the pile. Wade indicated that GCC would be grading this interface to keep the downcutting at a minimum. The stockpiled refuse windrows were being spread and compacted during the inspection on the lower RDA. Wade noted that the northern edge of the pile needs to be sloped back to the south a bit to maintain the out slope design. GCC will continue to improve this area of the pile.
