III. Comments - Compliance (Continued) 2) Sediment pond 006 on the, southeast side of the refuse pile had . silted in. This pond must be cleaned. In addition, the road from the sediment pond to the conveyor had been eroded. This erosion should be repaired and since this portion of the road is no longer used, it .should be reclaimed. 3) The piezometers installed in the refuse pile have been only partially backfilled. To avoid water running into these holes and giving false readings, the holes must be completely backfilled. 4) The drainage ditch below the north side of the Mine 1 stockpile must be cleaned. Presently, the ditch is blocked by coal pushed from above. 5) The berm around the Rock Tunnel powder magazine had evidently been pushed down during grading operations. This berm must be restored. 6) A berm must be built along the south side of the ramp/road leading to the pump at artic circle. A minor fuel spill was evident at the time of this inspection. This berm will assure that the drainage will enter the artic circle ponds. 7) The disturbed and undisturbed drainage systems at Mine #1 had been repaired, but during repairs, a berm ,was pushed in front of the disturbed drainage culvert inlet. 8) The berm containing runoff on the Mine #1 strip pit bench had been rebuilt plus another berm had been built. .on a lower bench. 9) The -Mine 5 disturbed drainge ditch that parallels Coal Creek must be redefined. Evidently material was pushed into and up to the bench during removal of the Mine 5 bin. Any runoff would now flow into Coal Creek. 10) Portions of the storage area south of the warehouse drain into the undisturbed area between the storage pad and Dutch Creek. The berm along this area should be extended to the warehouse pond. 4.06 Topsoil 1 ) Topsoil was being actively stripped .from the refuse pile extension area and replaced ori' the recently graded portions of the refuse pile. 2) The topsoil stockpile above the Mine 1 coal stockpile area should be pushed away from the coal stockpile, regraded, and a topsoil marker erected.
