<br /> <br />Bear Creek Quarry (M-1977-344) Permit Amendment <br />Holcim US Inc, 3500 Highway 120, Florence, CO 81226 <br />Phone (719) 288-1443 www.holcim.us 73 <br />2.9 Exhibit I: Soils Information (Rule 6.4.9) <br />There are 16 soil types within the Mining Permit and Affected Area Boundary, with a majority of the soil <br />types within Fremont County. Vegetation is interdependent with soil type being a combination of the parent <br />material, climatic factors such as temperature and rainfall, and the availability of water and nu trients within <br />the soil matrix (Appendix 4.9). The soils present in the Mining Permit and Affected Area Boundary for each <br />county are described below. <br />2.9.1 Fremont County Soils <br />Thirteen of the sixteen soil types within the Mining Permit and Affected Area Boundary are in Fremont <br />County. Below are descriptions of the relevant soil series from the USDA NRCS Soil Survey of Fremont <br />County Area, Colorado (USDA 1995). <br /> <br />2.9.1.1 Aquic Ustifluvents (similar to Pueblo County Las Animas series) <br />Aquic Ustifluvents are deep, moderately well drained and somewhat poorly drained soils on <br />stream terraces and flood plains. These soils formed in stratified alluvium. Slopes are 0 to 1 <br />percent. The average annual precipitation is 11 to 13 inches, and the average annual air <br />temperature is 51 to 53 degrees F. Depth to bedrock is 60 inches or more. The A horizon is fine <br />sandy loam, loam, or silty clay loam. <br /> <br />2.9.1.2 Kim Series <br />The Kim series consists of deep, well drained soils on fans, plains, side slopes, fan terraces, <br />stream terraces, and terrace breaks. These soils formed in alluvium and in eolian material. Slopes <br />range from 0 to 15 percent. The average annual precipitation is 11 to 15 inches, and the average <br />annual air temperature is about 48 to 53 degrees Fahrenheit (°F). The soils are fine-loamy, mixed <br />(calcareous), mesic Ustic Torriorthents. The A horizon is mildly alkaline or moderately alkaline. It <br />is loam or fine sandy loam. <br /> <br />2.9.1.3 Cascajo Series <br />The Cascajo series consists of deep, excessively drained soils on terrace edges, breaks, fan <br />terraces, knobs, hills, and ridges. These soils formed in gravelly and sandy, calcareous alluvium. <br />Slopes range from 10 to 40 percent. The average annual precipitation is 10 to 15 inches, and the <br />average annual air temperature is about 49 to 53°F. The soils are sandy-skeletal, mixed, mesic <br />Ustollic Calciorthids. <br /> <br />2.9.1.4 Manvel Series <br />The Manvel series consists of deep, well drained soils on plains, foot slopes, fans, stream <br />terraces, and swales. These soils formed in alluvium derived from limestone and shale. Slopes <br />range from 0 to 8 percent. The average annual precipitation is 12 to 14 inches, and the average <br />annual air temperature is 51 to 53°F. The soils are fine-silty, mixed (calcareous), mesic Ustic <br />Torriorthents. The A horizon is silt loam or silty clay loam. <br /> <br />2.9.1.5 Minnequa Series <br />The Minnequa series consists of moderately deep, well drained soils on plains, breaks, and <br />ridges. These soils formed in alluvium and residuum derived from limestone and shale. Slopes <br />range from 2 to 15 percent. The average annual precipitation is 11 to 13 inches, and the average <br />annual air temperature is 50 to 53°F. The soils are fine-silty, mixed (calcareous), mesic Ustic <br />Torriorthents. <br />
