Exhibit Page 28 <br />EXHIBIT I -SOILS INFORMATION <br />1. Source(s) of Information: USDA Soil Survey preliminary data, prepared by <br />NRCS Soil Survey Team, Durango, CO, and provided in hardcopy and electronic form <br />by Dolores Soil Conservation District. <br />2. Significant concerns in soils management: Prevention of water erosion, slowing <br />of rapid runoff, and prevention of downstream siltation. <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 obtained from the soils topographic map attached to a letter <br />from Dolores Soil Conservation District, 29 JAN 2002. No soils survey has been <br />published for Montezuma County. Unfortunately, the map was not of sufficient quality <br />' to reproduce for use, and the information has therefore been converted to an AutoCAD <br />map and included in this Exhibit. <br />' 5. The soils descriptions provided in Table B-2-1 are taken from attachments to the <br />same letter. Field observations have confirmed the general accuracy of the mapping <br />' and descriptions as being valid for this site. Most of the soil on the site appears to be. <br />There are many areas where cobbles appear on the surface and throughout the soil <br />profile. <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 topsoil. The objective is to provide as high quality grassland as feasible at <br />the end of mining activities. <br />
