EXHIBIT E RECLAMATION PLAN AND TIMETABLE RECLAMATION PLAN This is a dryland site with no special or unique character- istics other than it contains a deposit of material suitable for resurfacing county roads. Average annual forge production is approximately 1800 pounds per acre. Tall grasses make up approx- imately 65% of the vegetative cover and the plant community is mostly grasses. The species of vegetation found on the site are Prairie Sandreed, Little Bluestem, Sideoats Gramma, Western Wheatgrass, Sand Bluestem, Sand Bluestem, needleandthread, Switchgrass, Sand sage and assorted weeds. These species makeup 90 to 95% of the grass species on the site. The proposed future use of this site is to return it to it's existing use of rangeland. The landowners agree that this final land use is probably best for this arid piece of ground. Mining will create a 20 to 25 foot depression in the pasture. The nature of the land is such that there is no water on the site and the land has little use for anything other than its current use. This makes the reclamation plan very simple in that, the county will shape, resoil and revegetate the area with grass seed once mining is complete. Review of MAP EXHIBIT F- RECLAMATION PLAN MAP shows how we believe the site will look once mining is complete. The slopes along the outside perimeter of the mining area will be graded 3h to lv as mining progresses. One of two methods will be used, either they will be mined at the 3h to lv slope or the working face will be mined vertical and then a cut/fill operation will be done. An example of is shown on MAPEXHIBITC-1 in the northwest corner where the working face meets the side slope. Note that any slope area to be left when mining is complete, will be created as mining progresses. By preparing this outer perime- ter of the site for reclamation we are reducing the amount of work necessary to reclaim the site when mining is done. If the cut/fill option is used, an adequate setback will be left around the perimeter of the site to do the grading. The simple formula to be used is; ((depth of mine face x 3)=2)+setback, i.e., ((20x3)=2)+15=45.0 feet. Whenever mining stops for a given year, the working face will be graded to a 3:1 slope so it is stable during period when there is no mining activity. This will eliminate a near vertical highwall in case livestock or wildlife use the mine during down 13
