STOVER & ASSOCIATES, INC. <br />2352 NORTH 7 STREET, UNIT B <br />GRAND ]UNCTION, COLORADO 81501 <br />PHONE: (970) 245 -4101, FAX 242 -7908 <br />Janet Binns <br />Division of Reclamation, Mining and Safety <br />1313 Sherman St., Room 215 <br />Denver, CO 80203 <br />Re: New Elk Mine Permit C- 1981 -012 <br />Technical Revision Application No. 65 <br />West Development Waste Disposal Area, Sediment Drying Area <br />Dear Ms. Binns: <br />RECEIVED <br />APR 1 8 901? <br />Division of I- eciamation, <br />Mining and Safety <br />On behalf of New Elk Coal Company, (NECC) enclosed is an application for a technical revision to <br />construct a new development waste disposal area (DWDA), soil storage area, topsoil pile, <br />associated ditches, and expansion of Containment Area No. 2, near the west ventilation fan. <br />This technical revision application also includes a sediment drying area to be located in the old <br />non -coal waste disposal area. <br />The proposed location of the West DWDA is near or in an alluvial valley floor. However, as <br />discussed in the permit document, the operation proposed by NECC produced coal in commercial <br />quantities and was located within or adjacent to an alluvial valley floor prior to August 3, 1977. <br />Therefore, operations may proceed despite their close proximity to an alluvial valley floor. <br />Exhibit 19(22) presents the sedimentation control plan. Ditch 28 has been removed in part <br />where the West DWDA will be located, and realigned to flow around the soil storage area as <br />shown on Map -14. As originally designed, D28 will flow to Containment Area No.1, as will runoff <br />from the soil storage area and sediment drying area. <br />The majority of the west DWDA and associated facilities is in area that has been previously <br />disturbed. However, there will be an additional 0.9 acres of new disturbance created in the <br />footprint of the west DWDA and a small area in the footprint of the soil stockpile. <br />A reclamation estimate is provided as Exhibit 28. Data enclosed to support this technical revision <br />are listed below. <br />Sincerely, <br />: C>G'i?v j»Lc CAt A. - t ' <br />Tamme Bishop, P.E. <br />Project Engineer <br />
