Mechanical alteration of the terrain is hazardous, and <br /> any mechanical backfill and grading operations must be done subject: <br /> to safety considerations. <br /> Mid-Continent believiys that, to the extent allowable by MLRD/OSM, <br /> the slopes should be allowed to reclaim themselves naturally. <br /> [}itches and culverts will remain to improve the watershed. <br /> Sediment ponds will be reclaimed. <br /> 7Ihe final slopes above and below the roads will be revegetated. <br /> Stability of slopes, given the steep natural terrain, is of <br /> paramount. concern for final reclamation. <br /> if Mid-Continent weave required to place large amounts of fill <br /> against the road cuts for the purpose of eliminating the roads <br /> altogether, we feel -that serious stability problems would result. <br /> significant erosion of the fill , and any topsoil placed over it, is <br /> quite likely. <br /> An extensive study of the configurations, geotechnical conditions <br /> and avalanche danger of the roads has been completed and is <br /> included in App. V-E-2 . <br /> As noted in the study, the danger of eroding fill is signficant. <br /> Avalanches are a natural phenomenon in the area and the <br /> development of the haul roads or mine benches has not <br /> increased the avalanche danger. Haul roads or mine <br /> benches act as artificial barriers to individual <br /> avalanche paths and reduce their energy. They are thus <br /> beneficial in reducing the avalanche hazard . . <br /> Avalanches contribute to increased erosion of such fills. <br /> 22 Revised 2/92 <br />
