6.4.5 Exhibit E <br />Reclamation Plan <br />Reclamation to rangeland will occur concurrently with mining in a rolling <br />sequential fashion. As topsoil and waste rock /overburden are removed from the <br />subsequent working face, they will be placed on slopes and floors of the previously <br />mined out areas or stockpiled on the floor of the pit. Topsoil and waste <br />rock /overburden stockpiles from the first working face will be used to reclaim the <br />floor and slopes of the initial excavation. <br />Throughout mining, slopes will be maintained at 3H:1V minimum. Waste <br />rock /overburden will be placed on the pit floor as quantity allows. Four to six inches <br />of topsoil will be placed on affected surfaces. If necessary, surfaces will be <br />roughened prior to seeding. The slopes and pit floor will be seeded upon completion <br />of waste rock /overburden and topsoil placement. <br />The operator will use the NRCS recommended and DRMS approved seed mix <br />for the neighboring Verhoeff Pit to the west. If drill seeded, spacing will occur at <br />seven to ten inch spacing intervals to a depth of 1/4 to 1/2 inches. If broadcast <br />seeded, 13.2 PLS Ibs /acre will be placed. NRCS did not recommend mulch or soil <br />amendments for the Verhoeff Pit and will not be used on this site unless NRCS <br />communicates to the contrary. The side mix is described in Table 1. <br />Table 1: NRCS Recommended Seed Mix <br />Species <br />PLS /Acre <br />Blue grama <br />0.6 <br />Sideoats grama <br />2.3 <br />Western wheat grass <br />3.2 <br />Sand dro seed <br />0.2 <br />Yellow sweetclover <br />0.4 <br />All mining structures will be reclaimed including the interior haul road and <br />stormwater diversion structures. No ponds or streams are on site. All buildings are <br />manufactured portable control vans. No waste rock dumps, underground mine <br />openings, or ditches are anticipated at the site. <br />Plant Growth Medium Preservation: <br />Throughout the mining area, salvageable surface material will be removed <br />with an excavator and stockpiled for use in final reclamation. <br />Weed Control Plan <br />Upon commencement of reclamation, the area will be monitored for noxious <br />weeds and implement appropriate methods to manage weed growth. Bent County <br />Weed Control Program will be contacted for recommendations in the event noxious <br />weeds develop. <br />k, <br />
