Detailed data on chemical and physical characteristics are only <br />presented for the soils in the area to be mined. The disturbances <br />associated with facility construction on lands adjacent to the <br />mining area are very small in size for each soil type, currently no <br />additional facilities are planned at the Colowyo mine. <br />Twelve (12) soil series as mapped by the Soil Conservation Service <br />(SCS) are found within 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 Loams <br />X-110 Kemmerer - Yamac Complex <br />RL Rock Ledge <br />The soil series are delineated on the Soils - North Map (Map 5) and <br />the Soils - South Map (Map 6). <br />• Soil profile descriptions and Range Site Descriptions from <br />information provided by Soil Conservation Service are found in <br />Exhibit 9, Soils Information. <br />The descriptions of the soils series are as follows: <br />03B-Havre Fine Sandv Loam, 0 to 5 Percent S1oAes <br />This is a deep, well drained soil that occurs along drainage ways <br />in and adjacent to the permit area. A very small area (about 1 <br />acre) of this series was disturbed by the access road, no addi- <br />tional activity is anticipated on areas of this series. Therefore, <br />detailed chemical and physical data has not been collected for this <br />series. It developed in stratified alluvium from sandstone and <br />shale and is on flood plains and terraces. The average annual <br />precipitation ranges from 12 to 16 inches, the average annual soil <br />temperature is 42° to 47°F, and the frost-free season is 75 to 95 <br />days. <br />Included with this soil in mapping are small areas of Homelake, <br />Glendive, and Havre saline phase soils. <br />2.04.9-2 <br />
