RECLAMATION PLAN EXHIBIT E ' Upon completion of mining the site will be reclaimed for use as rangeland. As stated in Exhibit D, reclamation of the site will occur in stages. ' Topsoil, as it is removed during mining phases, will be stockpiled in a non-erosive configuration to be used during final reclamation. Topsoil stockpiles, if intended to be used for reclamation, will be seeded to grass and kept free of noxious weeds if they remain on the site for more than two years. At the completion of Phase 1 and Phase 2 the slope areas will be re-seeded in the fall or spring that year. The slopes will be top soiled by a loader carrying the topsoil to the top of the slope and dumping the material down the slope. A dozer will crawl on the slope and spread the topsoil to a four to six inch depth. Rough areas and dozer tracks will form pockets on the slopes to catch the seed for revegetation. During final reclamation slopes the mine floor will be scarified and the topsoil will be spread to a minimum depth of four to six inches. Seed will be planted in the fall or spring, using a broadcast method of 28 pounds per acre. The seed, as recommended by the Natural Resource Conservation Service (MRCS), will be pubescent wheat grass. Fertilizer and mulch will also be utilized on ' the site as recommended by the NRCS. Straw mulch will be crimped in at one ton per acre. During mining and for a period of two years following reclamation, the disturbed area will be monitored for noxious weeds. Chemical pesticides will be used to control weeds. If significant weed invasion occurs, mechanical controls, such as mowing, will be used second. The following estimates of reclamation costs are based on a period in time when the 1 permitted area would have the most disturbances. Total disturbed area will not exceed more than 22 acres at any one time. 11 8 t
