<br />EXHIBIT I <br />SOILS INFORMATION <br />The proposed excavation azea has a gentle slope of 3.6 to 8% towards the south. Soils of <br />the area have been mapped and described in the "United States Department of Agriculture, Soil <br />Conservation Service: Soil Survey of Aspen-Gypsum Area, Colorado", 1992. The soils present <br />aze: <br />(26)(28) DAHLQUIST-SOUTHACE: (Approx. 50% Dahlquist, 40% Southace) <br />The Dahlquist soil is deep and well drained. It formed in alluvium derived from <br />material of mixed mineralogy. Typically, the surface layer is brown cobbly sandy loam <br />about 6 inches thick. The upper 7 inches of the subsoil is very cobbly sandy clay loam. <br />The lower 10 inches is very cobbly sandy loam. The substratum to a depth of 60 inches is <br />extremely cobbly sandy loam. The soil is noncalcazeous to a depth of 13 inches and <br />calcazeous below that depth. Permeability is moderate and available water capacity is <br />low. Runoff is slow, and the hazard of water erosion is moderate. <br />The Southace soil is deep and well drained. It formed in alluvium derived <br />dominantly from mixed mineralogy. Typically, the surface layer is brown very stony <br />sandy loam about 3 inches thick. The upper 7 inches of the substratum as very stony <br />sandy loam. The next 12 inches is extremely stony sandy loam. The lower part to a <br />depth of 60 inches is extremely stony loamy coazse sandy. Permeability is moderately <br />rapid and available water capacity is low. Runoff is slow, and the hazard of water erosion <br />is slight. <br />Map Unit 26 is used mainly for rangeland or for pastures. Thus, the topsoil found in this <br />area is suitable for establishing and maintaining plant growth during reclamation phases. <br />(42) FLUVAQUENTS: <br />This broadly defined unit consists of deep, somewhat poorly drained, nearly level <br />soils on flood plains and alluvial valley floors. These soils formed in alluvium. <br />Fluvaquents aze stratified and vary widely in texture and in depth to sand, gravel, and <br />cobbles. Typically, the surface layer ranges from loamy sand to a fine sandy loam or <br />from silt loam to clay loam. The underlying layers aze generally sandy loam or loam <br />stratified with sand, gravel, and cobbles. In some azeas gravel and cobbles aze on or near <br />the surface. These soils aze occasionally flooded for brief periods in late spring and early <br />summer. <br />This soils group is found primarily in the lower terrace of the Gypsum Ranch. <br />(89) MUSSEL LOAM: <br />This deep, well drained soil is on terraces and foot slopes. It formed in alluvium. <br />Typically the surface layer is light gray loam about 8 inches thick. The upper 34 inches <br />of the substratum is sandy clay loam. The lower part to a depth of 60 inches is gravelly <br />
