EXHIBIT C <br /> PRE-MINING AND MINING PLAN MAPS <br /> A site plan of the nahcolite mine area is shown in Figure C-1. The site plan includes the following: <br /> • lease area outlined; <br /> • closest section corners with township, range, and sections identified; <br /> • surface plant access road; and <br /> • surface facility locations. <br /> Not all topsoil stockpiles have been shown on Figure C-1 because these areas will be selected by <br /> the construction field staff in order to place the topsoil in the most advantageous locations. As <br /> discussed in Exhibit E Reclamation Plan, salvaged soils will be stockpiled in designated storage <br /> locations as near as possible to salvage and re-use locations. Topsoil stockpiles for roads and <br /> pipeline corridors will be linear and located along and generally up-gradient of the road or corridor. <br /> Stockpiles will be located on stable sites in areas that are not planned for disturbance and where <br /> wind and water erosion potentials are minimized. Stockpile areas will avoid, or will be adequately <br /> protected form, concentrated surface water flows. Where needed, erosion and sediment control <br /> structures such as ditches, berms, and silt fencing will be placed and properly maintained around <br /> the perimeter of stockpiles until vegetation cover is established on the stockpiles. Such vegetation <br /> cover will be established using the seed mixture listed in Table E-1 in Exhibit E. Seeding will occur <br /> on each stockpile during the first normal planting period (i.e., fall or spring) following stockpile <br /> placement. <br /> All immediately adjacent surface owners of record are shown on Figure C-2. Area topography, <br /> stream drainages and existing structures are shown on Figure C-3. Major vegetation associations <br /> are shown on Figure C-4. Soil mapping units are shown on Figure C-5. Typical pipe rack <br /> construction is shown on Figure C-6, typical well field pad construction is shown on Figure C-7, and <br /> typical pond liner construction is shown on Figure C-8, <br /> G:\LMNA78545.002\Reclamation\Reclamexh.DOC C-1 <br />
