<br /> <br />EXHIBIT ~- SOILS INFORI~ATION <br />5 <br />' Soils data for borrow area C was obtained from the U.S. Soil <br />Conservation Service (Source: Soils Survey of Grand County <br />Area, Colorado -- Advance Copy, Unpublished). The soils data <br />for borrow area C are shown on Figure I-1 and are described <br />' below. <br />' Soil Number 93 - Youga Loam, 2 to6 Percent Slopes. This is a <br />deep, well drained, gently sloping to moderately sloping soil <br />which is formed in glacial drift and colluvium. Typically the <br />surface layer of this soil is dark grayish brown loam about <br />' 4 inches thick. The upper 10 inches of subsoil is dark grayish <br />brown loam. The lower 42 inches is reddish yellow clay loam <br />about 42 inches thick. The substratum is reddish yellow clay <br />loam that extends to 60 inches or more. Permeability is <br />moderately slow and the effective rooting depth is 60 inches <br />or more. Available water capacity is high. As shown on Figure <br />' I-1, this soil occupies practically all of the upper levels of <br />the bench included in the permit area. <br />' Soil Number 83 - Tine Cobbly Sandy Loam, 15 to 55 Percent Slope. <br />This is a well drained, moderately steep to steep soil and is <br />found on terrace breaks. Typically the surface area is brown <br />' cobbly sandy loam about 14 inches thick. The upper 9 inches of <br />the underlying material is pale brown, very cobbly loamy sand. <br />The lower part is extremely cobbly sand that extends to 60 <br />' inches or more. Permeability is high and effective rooting depth <br />is 60 inches or more. The available water capacity is low and <br />surface runoff is medium. This soil is found on the steeper <br />slopes between the upper bench area and the alluvial area of <br />' Willow Creek and the tributary to the east of the permit area. <br />' Soil Number 25 - Cumulic Cryaquolls, Nearly Level. These soils <br />occur on floodplains and are formed in alluvium and alluvial <br />outwash. The profile ranges from sandy loam to clay and is <br />' commonly stratified. Surface layer is dark colored and is 20 <br />or more inches thick. The water table is usually within 10 to <br />24 inches of the surface during the growing season. Surface <br />runoff is slow. These soils are found in the alluvium of Willow <br />' Creek and to some extent along the tributary to Willow Creek <br />on the east side of the permit area. No disturbance of these <br />soils is anticipated as a result of mining operations. <br />1 <br />' I-1 <br />
