• Exhibit Page 30 • <br />EXHIBIT I -SOILS INFORMATION <br />1. Source(s) of Information: USDA Soil Survey preliminary data, prepared by Soil <br />Survey Team, Durango, CO. <br />2. Significant concerns in soils management: Prevention of water and wind <br />erosion, and 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 NRCS. No soils survey has been published for Montezuma County. <br />Unfortunately, the map was not of sufficient quality to reproduce for use, and the <br />information has therefore been converted to an AutoCAD map and included in this <br />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 />Apmay and Schrader loam, with only very small areas of Dalmatian loam and the <br />Ustifluvents soil. There are many areas where cobbles appear on the surface and <br />throughout the soil profile. <br />6. Topsoil stripping, storage, and replacement: For planning purposes and based <br />on test pits, it is assumed that an average of 2 feet of material will be removed, and will <br />require screening to remove oversized rocks (cobbles) to improve the quality of the soil <br />for use. In all areas where topsoil is removed, the following will be done as much as <br />possible: <br />• the upper 24 inches of soil will be removed and stockpiled. <br />• the soil will be screened, and the finer fraction (approximately two inch or less) will <br />be stockpiled and used for soil (primary) and backfill (excess) as needed. Soil will <br />placed to a depth of 12 inches or more. <br />• Oversize material screened out will be used as gravel. <br />The objective is to provide as high a quality grassland and pond areas as feasible at the <br />end of mining activities. <br />See Exhibit D for information on topsoil preservation in stockpiles.
