SOILS INFORMATION <br />EXffiBIT I <br />A general soils report was conducted by the NRCS in 2004. Soil thicknesses are based on <br />boreholes which United Companies drilled and the NRCS soil survey. Topsoil and overburden <br />thicknesses range between 4 and 15 feet. Generally, the topsoil and overburden is thin on the <br />northwest comer of the property and gets thicker towards the southeast, where the topsoil and <br />overburden are the thickest. Approximate soil boundaries can be seen on Map C-1. Soil <br />descriptions for all of the soil types described below can be found in Appendix B. <br />Nine NRCS soil mapping units occur within the general permit area and surrounding area. Note <br />that the first two are categorized in one description. They are listed below: <br />1) Uncompahgre fine sandy Laom, mapping unit Uh and Un, occurs on slopes between 0 to 2 <br />percent grade in elevations between 4,800 and 6,600 feet. The typical soil profile consists of 8 <br />inches of gray fine sandy loam, 6 inches of grayish brown loam, and 46 inches of light brownish <br />gray loam stratified with thin lenses of fine sandy loam and clay loam. <br />2)Wet alluvial land, mapping unit Wa, occurs on slopes between 0 to 6 percent grade. These <br />areas typically have thin topsoils and a low permeability. <br />3) Uncompahgre clay loam, mapping unit Uc, occurs on slopes between 0 to 2 percent grade in <br />elevations between 4,900 and 6,600 feet. The typical soil profile consists of 8 inches of gray clay <br />loam, 6 inches of grayish brown loam, and 46 inches of light brownish gray loam stratified with <br />thin lenses of fine sandy loam and clay loam. <br />4) Sagers silty clay, mapping unit BdA, occurs on slopes between 0 to 2 percent grade in <br />elevations between 4,900 and 6,200 feet. The typical soil profile consists of 6 inches of grayish <br />brown silty clay and 54 inches of light yellowish brown silty clay loam. <br />5) Salorthids, mapping unit Sa, occurs on slopes between 0 to 5 percent grade in elevations <br />between 4,900 and 6,500 feet. The typical soil profile consists of 10 inches of light brownish <br />Anderson Pit February OS I-1 <br />
