November 4, 2020 C-1981-035/King Coal Mine LJW <br />The East Clear Water Ditch that traverses the hillside above the upper refuse pile was observed and can be seen in <br />Photos One and Two. The ditch was in good condition at the time of the inspection and had no standing water or <br />evidence of recent flows. The downslope portion of the CWD has been coated in shotcrete which was stable at the <br />time of the inspection. No noxious weeds were observed growing within the CWD and no signs of erosion were <br />noted. <br />The West Clear Water Ditch has been lined with river rock materials and was stable at the time of the inspection. <br />No state listed noxious weeds were noted growing in the ditch and no evidence of erosion was observed. The <br />West Clear Water Ditch is shown in Photo Three. <br />All internal drainage structures including ditches and culverts used to convey water from the affected areas to the <br />sediment ponds located near the entrance of the facility were observed. All culverts and ditches were clear and <br />appeared to be functioning as designed. One culvert near the top of the Upper Refuse Pile Access road was called <br />out as a maintenance item during the previous inspection. Conversations with the Operator indicate that the <br />replacement culvert has been delivered but not yet installed, this is not considered a problem at this time as it will <br />be completed soon. <br />The West sediment pond, seen in Photo Four, was observed and contained no standing water, the sediment load <br />does not appear to have increased since the previous inspection. The witness indicator located near the center of <br />the pond suggests that the sediment load is well within the design specifications and is not considered a problem at <br />this time. <br />The East Sediment Pond also contained no standing water and does not appear to have an increased sediment load <br />from the previous inspection. The berms surrounding both ponds are well vegetated, with no state listed noxious <br />weeds observed and appeared to be stable at the time of the inspection. The East Sediment Pond can be seen in <br />Photo Five. <br />King II Facility: <br />At the King II facility all ditches, culverts and water conveyances were inspected at this time. The culverts <br />adjacent to the shop and office facility that were called out as maintenance items during the previous inspection <br />have been cleaned and repaired. They are no longer considered a problem at this time. All other culverts and <br />ditches were unobstructed and appeared to be functioning as designed at the time of the inspection. A culvert <br />along the access road used to convey water from the west side of the access road to the east side was observed to <br />be partially blocked and GCC staff was observed clearing the culvert prior to the conclusion of this inspection. <br />The sediment pond located at the King II facility was in excellent condition, shown in Photo Six. A minimal <br />amount of standing water, generated from washing and equipment use within the affected area, was present. The <br />sediment load and water level within the pond are well within the design specifications and the pond was not <br />discharging at the time of the inspection. The berms surrounding the pond are well vegetated and showed no signs <br />of erosion. No state listed noxious weeds were noted in or around the sediment pond area. <br />The hazardous materials and bulk fuel storage area was observed and can be seen in Photos Seven and Eight. All <br />containment structures were intact and appeared to have sufficient capacity to contain any potential spills.
