March 15, 2023 C-1981-035/King Coal Mine CCW replace the straw waddles to ensure the drainage grate continues to function as designed. Pleas complete these maintenance items as soon as the ground conditions allow. Sumps located within the King II facilities area were observed to be in good condition. The sumps had plenty of storage capacity left. The sumps were stable with no erosional features noted. PROCESSING WASTE/COAL MINE WASTE PILES—Rule 4.10 and 4.11 Drainage Control; Surface Stabilization; Placement: Coal waste piles are located at the King I area. An upper and a lower refuser pile receive coal refuse from the King II facilities area. Refuse was stockpiled on the lower pile at the time of the inspection. Once the refuse area dries out in the spring coal waste will be transported to the upper stockpile for spreading and compaction. The upper coal waste pile could not be accessed due to the extremely muddy ground conditions. The slope of the upper refuse pile was covered with snow. There were no indications of instability or erosion. The lower refuse pile also had snow covering its slope. There were no erosional concerns observed or indications of instability. A minor rill was observed on the west side of the lower refuse pile. The rill extended to the east side of the haul road and then down the face of the stockpile. The rill had rocks placed in it to prevent further down-cutting and enlargement. The rill was observed in previous inspections and has not increased in size. This rill will be repaired when springtime conditions allow. The rill did not appear to be affecting the stability of the slope of the refuse pile. Refuse material was stockpiled on the eastern portion of the lower pile (Photo 9). Any moisture and runoff from the stockpiled material will drain across the top of the lower pile as designed, into the surface drainage ditches. These ditches then report to the sediment ponds below and to the north of the refuse piles. No off-site impacts were observed. ROADS—Rule 4.03 Construction 4.03.1(3)/4.03.2(3),Drainage 4.03.1(4)/4.03.2(4), Surfacing and Maintenance4.03.1(5) and (6)/4.03.2(5) and(6), Reclamation 4.03.1(7)/4.03.2(7): The main haul road at the King I area was stable and muddy. There were no erosional concerns identified. The haul road ditches were in good condition and unobstructed. Runoff was being transported as designed. The haul road at the King II area was also observed to be in good repair. The haul road was stable with no erosional features observed. The haul road ditches were clear of debris and functioning as designed. There were no off site impacts identified. SUPPORT FACILITIES -Rule 4.04: The majority of the support facilities are located at the King II area. The pad for all the facilities was muddy but stable. Coal is processed through an air jig and shaker before the coal product is placed in a stockpile. On-road haul trucks are then filled and exit the King II area on the haul road. The facilities area was well kept and no erosional features were identified(Photo 10). Three maintenance items were identified and are outlined in the Hydrologic Balance section of this report. SIGNS AND MARKERS—Rule 4.02: The Division observed the required mine identification signs posted at the entrances to the King I and King II portions of the permit area. The signs were able to be viewed in unobstructed locations. The signs display the required contact information for the permittee and the Division. Topsoil pile markers were observed to be placed on top of the stockpiles in clear locations.
