Exhibit Page 28 <br />EXHIBIT I - SOILS INFORMATION <br />1. Source(s) of Information: USDA Soil Survey, Portions of Montezuma and <br />Dolores Counties, Colorado, (Web Soil Survey) provided information incorporated in <br />this exhibit. The full report is available and is incorporated by reference (51 pages).6 <br />2. Significant concerns in soils management: For this type soils and terrain the <br />major concerns are prevention of water erosion, slowing of rapid runoff, and prevention <br />of downstream siltation. These issues are addressed and resolved in the mining and <br />reclamation plan, and are the basis for reclamation seed mix selections. <br />3. Reclamation seed mix (for grasses) recommended by Natural Resources <br />Conservation Service for area is provided in Exhibit J. <br />Method of application: Drill and /or broadcast (on steeper slopes and stockpiles). <br />4. The soils map is taken from the report (item 1). <br />5. The soils descriptions provided in Table B -2 -1 are taken from the same report. <br />Field observations have confirmed the general accuracy of the mapping and <br />descriptions as being valid for this site. There are many areas where cobbles appear <br />on the surface and throughout the soil profile as indicated in the report. <br />6. Topsoil stripping, storage, and replacement: For planning purposes and based <br />on test pits, it is assumed that an average of 0.5 feet of material will be removed and <br />preserved as soil. The objective is to provide as high quality grassland as feasible at the <br />end of mining activities. Depending on the quality of soil found in the work area <br />(southeast portion of the site), this material may also be screened to remove large <br />cobbles before placement and restoration of the area to cropland. <br />6 www.websoilsurvey.gov, accessed most recently on 13 MAR 13 <br />
