Comments also describe any enforcement actions taken during the <br />inspection and the facts or evidence supporting the enforcement action. <br />undirected, overland flow which previously existed in this <br />location. <br />Maintenance work was needed in a number of locations along the <br />inside haulroad ditch which is adjacent to refuse areas RP-2/3, RP- <br />4, and RP-5. In several locations, temporary access roads lead <br />from the haul road onto the refuse disposal area, and the road <br />ditch is either culverted under the temporary road at the junction <br />with the refuse haul road, or extended across the temporary access <br />road. Several of the culverts (which range from 6" to 12" <br />diameter) were partially blocked, and need to be cleaned out, and <br />in other locations the ditch needed to be better defined. <br />The first culvert below the temporary coal storage loop road, on <br />the rail loadout access road had been recently cleaned out, and it <br />was apparent that substantial sediment had accumulated at the <br />culvert inlet prior to cleanout. The operator had placed straw <br />bales around the inlet after completion of maintenance. It is <br />recommended that in addition, a series of straw checks be installed <br />along the Swale up gradient from the culvert to slow flows and trap <br />sediment above the culvert location. <br />The second haulroad ditch outlet below the County Road 65 junction <br />needs to be extended with riprap placed to the base of the road <br />fill, to prevent downcutting. <br />Hvdroloaic Balance <br />Refuse area perimeter ditches were conveying minor flows in most <br />areas at the time of the inspection. Major snowmelt runoff had <br />apparently occurred in the previous week, and there was evidence of <br />recent downcutting in some areas. Ditch capacities appeared to be <br />adequate, and disturbed runoff was contained and routed to the <br />refuse area sediment ponds. Ditch erosion will be repaired and <br />various erosion control structures will be installed as approved in <br />TR-39, beginning as soon as ground conditions dry sufficiently to <br />allow equipment access. -~ <br />RP-1 water level was approximately 4' below the top of the spillway <br />riser, and there was no discharge. Water had been pumped from RP- <br />2/3 the previous week. <br />RP-2/3 water level was approximately 2' below the top of the riser. <br />Water was very muddy from recent runoff. The pond was not <br />
