• • RECLAMATION PLAN <br />topsoil and overburden are only barely distinguishable. That is not the case here. The long history <br />of agricultural use for pasture and crop has created a highly differentiated soil on top of the native <br />sandy to silty material that forms the overburden. Topsoil will be salvaged separately. <br />Topsoiling will occur to a minimum depth of 6 inches (probably more), although that is <br />only the depth of the final, top layer. Actually, the depth will be greater than that because under <br />the topsoil will be many feet of overburden and wash fines that were placed in the backfilling <br />process. <br />Topsoil Protection - The Mining Plan (Exhibit E) discussed the topsoil locations and shape. <br />Immediately after the establishment of the topsoil locations they should be seeded to produce a <br />protective growth. The following mixture will be used for that protection. This mixture contains <br />those species of the final revegetation mixes that would be appropriate for use on a topsoil stockpile <br />where conditions will tend to be drier and hotter than the final revegetation surface after <br />redistribution of the soil. <br />Topsoi] Protection Seed Mix <br />Species pounds/acre PLS <br />(broadcast) seeds per <br />square foot <br />Cresced Wheatgrass -Fairway 5 34.66 <br />Intermediate Wheatgrass 8 17.81 <br />Canada Wildrye 3 7.3 <br />Ranger Alfalfa 4 19.28 <br />Sand Dropseed 0.25 29.8 <br />TOTAL = 20.25 108.85 <br />Revegetation <br />Revegetation of the site will involve primarily two locations.
