• 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. <br />The hillside spring water will be channeled to the River after the Colorado Department of <br />Public Health and Environment finds that the hillside spring water treatment pond is no longer <br />needed and after the appropriate channel designs are submitted to and approved by the <br />DRMS. <br />The hillside spring water treatment pond will be reclaimed after it is no longer needed. <br />Water will be pumped from the treatment pond and the embankment will be allowed to <br />dry as needed. The treatment pond embankment will be pushed into the pond to <br />establish approximate original contours. The area will then be revegetated in a manner <br />similar to the proposed revegetation plan described below. <br />The sediment pond will remain in place until the vegetation is established and pond <br />removal is authorized by the DMRS. 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 was <br />hauled to and disposed of in Somerset Mining Company's gob pile. <br />• MR -33 2.05 -35a 03/14111 <br />,� ppRavE� <br />3 /ya /I 1 <br />
