erosive, and as having a potential to slide into the adjacent Coal Creek. <br /> An estimate 54,000 cubic yards of coal refuse was cut out of the pile in order that a more <br /> desirable slope angle could be created. Most of this cut material was transported to the concrete <br /> disposal area created as a result of the Wash Plant Demolition Project. <br /> The refuse was placed over the demolished concrete and compacted in place. Placement of coal <br /> refuse over the demolished concrete is described in the permit reclamation plan. Because <br /> placement of this material, as a result of the Federally funded Huntsman Project, was <br /> accomplished without the use of money from the Liquidation plan, Mid-Continent and the <br /> bankruptcy Trustee received a substantial amount of work at no cost. <br /> Underdrains, similar to those installed while repairing the coal stockpile slumps, were installed at <br /> the fill areas on the Old Refuse Pile, and at the concrete disposal area. Corrugated metal pipe <br /> was placed in a drainage ditch located at the base of the Project Area in order to minimize any <br /> sediment contributed to that structure. Upon completion of the cut and fill operations, topsoil <br /> was imported to the site, and applied. Erosion control techniques were implemented and the area <br /> was revegetated. The cost of accomplishing this approximately 9 acre project, including the <br /> hauling and placement of refuse over the demolished concrete was $216,913. <br /> Dutch Creek Diversion Project <br /> The purpose of this project was to eliminate the need for the continued use of the Dutch Creek <br /> Flume, which was showing signs of future failure. Replacement of the flume was not <br /> contemplated in the permit. This project was accomplished using grant funds provided by the <br /> Office of Surface Mining. A naturally functioning stream channel was constructed through the <br /> eastern most portion of the old wash plant and office facilities area. Dutch Creek has been routed <br /> through this new stream channel, and now by-passes the flume. This Project cost $90,369, <br /> including excavation of approximately 27,000 cubic yards of earth,placement of rip rap <br /> materials, and hauling in topsoil for future use. <br /> FUTURE RECLAMATION PROJECTS <br /> In order to fulfill its statutory obligations, and to satisfy the reclamation plan and the needs of the <br /> site,the Division must complete the following reclamation projects: <br /> Steep Slope Revegetation - r <br /> As required by the permit and the Act, the remaining mine bench outslopes and the cut and fill 3 , <br /> slopes adjacent to the road system will be revegetated. A contract for this project has been <br /> awarded to an independent contractor. However the project has been delayed due to the claims , <br /> pending in the on-going litigation regarding steep slope reve etation. No other work at the mine f <br /> entry areas can be accomplished until this project is completed, thus effectively delaying <br /> completion of reclamation within Coal Basin. This project does not call for the use of the liquid <br /> erosion control blanket used at Mine 4 in 1997, due to the constraints of the targeted outslopes. <br /> Rather, techniques demonstrated to be effective at Mine 1 in 1996 will be utilized. The estimated <br /> cost of completing this difficult 49 acre project is $145,000. -2, ti «�o•s S r s,r : t�r� v•W- . <br /> 10 <br />
