EXHIBIT I SOILS INFORMATION The proposed excavation azea has a gentle slope of 3.6 to 8% towards the south. Soils of the area have been mapped and described in the "United States Department of Agriculture, Soil Conservation Service: Soil Survey of Aspen-Gypsum Area, Colorado", 1992. The soils present are: (2 (28) DAHLQUIST-SOUTHACE: (Approx. 50% Dahlquist, 40% Southace) The Dahlquist soil is deep and well drained. It formed in alluvium derived from material of mixed mineralogy. Typically, the surface layer is brown cobbly sandy loam about 6 inches thick. The upper 7 inches of the subsoil is very cobbly sandy clay loam. The lower 10 inches is very cobbly sandy loam. The substratum to a depth of 60 inches is extremely cobbly sandy loam. The soil is noncalcazeous to a depth of 13 inches and calcareous below that depth. Permeability is moderate and available water capacity is low. Runoff is slow, and the hazazd of water erosion is moderate. The Southace soil is deep and well drained. It formed in alluvium derived dominantly from mixed mineralogy. Typically, the surface layer is brown very stony sandy loam about 3 inches thick. The upper 7 inches of the substratum as very stony sandy loam. The next 12 inches is extremely stony sandy loam. The lower part to a depth of 60 inches is extremely stony loamy coazse sandy. Permeability is moderately rapid and available water capacity is low. Runoff is slow, and the hazazd of water erosion is slight. Map Unit 26 is used mainly for rangeland or for pastures. Thus, the topsoil found in thi: area is suitable for establishing and maintaining plant growth during reclamation phases. (42) FLUVAQUENTS: This broadly defined unit consists of deep, somewhat poorly drained, nearly level soils on flood plains and alluvial valley floors. These soils formed in alluvium. Fluvaquents aze stratified and vary widely in texture and in depth to sand, gravel, and cobbles. Typically, the surface layer ranges from loamy sand to a Fine sandy loam or from silt loam to clay loam. The underlying layers aze generally sandy loam or loam stratified with sand, gravel, and cobbles. In some areas gravel and cobbles are on or neaz the surface. These soils are occasionally flooded for brief periods in late spring and early summer. This soils group is found primarily in the lower terrace of the Gypsum Ranch. Q89) MUSSEL LOAM: This deep, well drained soil is on terraces and foot slopes. It formed in alluvium. Typically the surface layer is light gray loam about 8 inches thick. The upper 34 inches of the substratum is sandy clay loam. The lower part to a depth of 60 inches is gravelly
