• Exhibit Page 15 • <br />EXHIBIT E -RECLAMATION PLAN <br />GENERAL CONCEPT: <br />The mine will be reclaimed as a water resource (three ponds) surrounded by improved <br />irrigated pastureland and accessed by a road with trails. In general, soil stripped from <br />areas to be mined and fines (from processing) will be used to shape the edges of the <br />pit, and to divide the pit into three ponds, each with a separate water level. Slope of the <br />ponds below water level will be between 1V:2H and 1V:4H. Maximum slopes around <br />ponds above water level will be between 1V:2H and 1V:3H. Areas around the ponds <br />will be revegetated with pasture grasses, and selected areas will be planted with <br />shrubs. Selected areas along the shore of the ponds will be planted with willows and <br />other pond vegetation as recommended by NRCS. <br />Elevations and Sizes <br />The reclaimed land service will range in elevation from 7230 down to 7213.5 <br />(above water level in the ponds), sloping from preexisting elevations at the permit <br />boundary to areas (above water level in the ponds) of up to twelve feet below the <br />original ground level. The average unsubmerged ground surface will be about <br />four feet below the preexisting ground level. <br />Lag time <br />The time between initial disturbance and final reclamation will vary from five <br />years to one year. Because of the size and the post-reclamation use as a <br />developed water resource and the need to dewater when mining the lower level, <br />it is not possible to reclaim significant portions of the site until almost all mining is <br />done. <br />The objective of the reclamation is to create a stable topography and biological <br />community which can sustain the proposed post-mining use of the land and protect <br />downstream water quality and quantities. <br />As much as possible, soil and waste fines will be placed into stockpiles which can be <br />easily moved to their permanent locations as part of the reclamation, outlining and <br />defining the ponds which will be the major post-reclamation feature of the site. <br />STOCKPILE PROTECTION: <br />Any stockpiles of soil and waste fines will be seeded with temporary seed mix to <br />stabilize the stockpiles against wind and water erosion. Stockpiles will also be <br />protected as necessary against erosion and traffic, and weed invasion. (See Exhibit J <br />for information on seeding, Exhibit D for discussion of stockpiles.) <br />BACKFILLING AND GRADING: <br />Mining faces will be a vertical slope; topsoil stockpiles are placed above the mining <br />face. Waste fines will also be stored in stockpiles; primarily above the mining face but <br />also on the final floor of the pit, where they will form the base for ridges dividing the <br />three ponds. Fines stored on top of the face will be cut, together with the underlying <br />face, to 1 V:3H or 4H resulting in a slope approximately 20 feet high and 60 to 80 feet <br />wide. Excess material will be moved to adjacent faces to create similar slopes. Slopes <br />Four States Aggregates, LLC 30 DEC 2000 <br />Application for Permit: Line Camp Pit FSA-LCP-D1-001 <br />
