The portal face-up above the entries has been in place since 1934. A stability analysis <br />• of the portal area and access road was performed by Rocky Mountain Geotechnical <br />during 1982 (See exhibit 21). The report indicates that with the exception of the slope <br />above the main portal area, the access road both above and below has an existing <br />condition of marginal stability (indicated factors of safety between approximately 1.1 <br />and 1.3). The report further notes that the stability conditions in the post reclamation <br />condition will be in the order or 5% less because of the surcharge effect of placing fill on <br />the bench and access road. However, the overall nature of the stability condition at the <br />mine would remain essentially unaltered and marginal in nature. <br />Office Facilities and Other Surface Structures. A minimum of earthwork will be <br />necessary for the regrading of the surface facilities area. All facilities will be removed at <br />the conclusion of mining unless approved by the Division for future beneficial use, such <br />as limited residential use. <br />The sediment pond will remain in place until the vegetation is established and pond <br />removal is authorized by the DMG. The sediment pond will then be regraded to <br />. approximate original contour and reseeded. The growth media will be analyzed for <br />nutrients and amended as necessary. <br />There will be some waste coal to clean up prior to commencing backfill and grading <br />operations in the area of the existing coal stockpile. It is estimated that up to 2,543 <br />cubic yards of coal waste will be removed from the stockpile area. This material will be <br />hauled to and disposed of in Somerset Mining Company's gob pile. <br />2.05-35a <br />M R-as <br />(RN -o v) <br />!9 pP~ovEA t ~114~03 <br />Rev. 01103 <br />
