• Detailed data on chemical and physical characteristics are only presented for the soils in the <br />area to be mined. The disturbances associated with facility construction on lands adjacent to <br />the mining area are very small in size for each soil type, currently no additional facilities are <br />planned at the Colowyo mine. <br />Twelve (12) soil series as mapped by the Soil Conservation Service (SCS) are found within <br />the permit area. They are as follows. <br />03B Havre Fine Sandy Loam <br />14 Burnette Loam <br />17 Work Loam <br />19 Campspass <br />28 Forelle Loam <br />32 Yamac Loam <br />33 Pinelli Loam <br />101 Torriorthents -Rock Outcrop Complex <br />104 Borolls -Rock Outcrop Complex <br />105 Kemmerer - Moyerson -Silty Clay Looms <br />X-110 Kemmerer-Yamac Complex <br />RL Rock Ledge <br />The soil series are delineated on the Soils -North Map (Map 5) and the Soils -South Map <br />(Map 6). <br />~" Soil profile descriptions and Range Site Descriptions from information provided by Soil <br />Conservation Service are found in Exhibit 9, Soils Information. <br />The descriptions of the soils series are as follows: <br />03B -Havre Fine Sandv Loam. 0 to 5 Percent Slopes <br />This is a deep, well drained soil that occurs along drainage ways in and adjacent to the permit <br />area. A very small area (about: I acre) of this series was disturbed by the access road, no <br />additional activity is anticipated on areas of this series. Therefore, detailed chemical and <br />physical data has not been collected for this series. [t developed in stratified alluvium from <br />sandstone and shale and is on flood plains and terraces. The average annual precipitation <br />ranges from IZ to 16 inches, the average annual soil temperature is 42° to 47°F, and the frost- <br />free season is 75 to 95 days. <br />Included with this soil in mapping are small areas of Homelake, Glendive, and Havre saline <br />phase soils. <br /> <br />2.04.9-2 <br />
