EXHIBIT I - Soils Information <br />1. Source(s) of Information: USDA Soil Survey of Montezuma and Dolores Counties, <br />Colorado, issued 2008. See also the original letter from NRCS (then SCS) dated 26 <br />SEP 1994, part of exhibit I of the original application. <br />2. Significant concerns in soils management: The objective is to provide as high a <br />quality cropland as feasible at the end of mining activities. Major concerns are <br />prevention of water and wind erosion, and downstream siltation and transport of <br />salts downstream. <br />3. Reclamation seed mix as proposed is based on NRCS and/or Extension Service <br />recommendations. Seed mix for temporary stabilization and non-crop areas <br />discussed in Exhibit J. Method of application: Standard agricultural seeding <br />technique. <br />4. The soils map (next three pages) is taken from the soil survey (on-line data <br />available from NRCS on Web Soil Survey). The soils descriptions provided in the <br />original submission are taken from the Survey. Field surveys and previous mining, <br />have confirmed the general accuracy of the mapping for the area. <br />5. Soil stripping, storage, and replacement: For planning purposes and based on test <br />pits, it is assumed that an average of 1 foot of material will be removed. In all areas <br />where soil is removed, the following will be done as much as possible: <br />As much as possible, to include the upper 24 inches of soil, will be removed <br />and stockpiled. <br />• If necessary, the larger cobbles will be removed from the soil prior to <br />placement in the final location. <br />• Soil will placed to a depth of 6- 12 inches or more for reclamation: this is <br />necessary because of pre-law mined areas with no soil recovered (those <br />areas with code 87 on soils map. <br />Rooting zone material will be placed/replaced where possible to give a total <br />depth of 24 to 36 inches. <br />NOTE: Since the original application in 1994, NRCS has revised its <br />nomenclature for soils significantly, and 1994 Exhibit information is no longer <br />accurate. <br />Exhibits for 112(c) AM-02 Application - M-1994-108-2010- Page 48
