3-11 <br /> <br />The maximum overall slope within the work area will be approxi- <br />mately lv:3h in the upper portion of the area along the natural <br />cliff area. <br />The waste rock pile and the sediment pond will require backfilling <br />and grading. The waste rock area will be recontoured back into <br />the hillside. Drainages around the pile will he re-established <br />(see Figure 3.1-1). The sediment pond will be backfilled with <br />excess fill. Drainage ditches around and above the sediment pond <br />will be regraded. <br />All topsoil in the topsoil stockpile will be used for reclamation. <br />Topsoil will be scraped down to the level of the pre-existing <br />• soil surface, thus restoring the original surface topography in <br />those areas. <br />During storage, the topsoil stockpile will be stabilized with a <br />perennial vegetation cover resulting from drill seeding of 5 lbs/acre <br />Western Wheatgrass-Arriba, 5 lbs/acre Streambank Wheatgrass- <br />Soder, and 5 lbs/acre Thickspike Wheatgrass-Critana. Weed cover <br />will be controlled via the most appropriate technique. This will <br />decrease problems with weed competition during final reclamation. <br /> <br />
