• <br />C, <br />C <br />IX. Stream Buffer Zones -Rule 4.05.18 <br />The Eagle Mine Complex includes two structures which are located within 100 <br />feet of the perennial Williams Fork River. These two structures are a coal <br />storage silo and a 48-inch cross country conveyor. The conveyor is an <br />enclosed structure as it crosses the river and the highway, therefore, <br />minimizing disturbance to the stream. The coal storage silo is a concrete <br />structure utilized to load railroad cars. These two variances from the 100 <br />feet buffer zone for perennial streams have been granted by the Division upon <br />finding: 11 that the original stream channel will be restored; and 2) during <br />and after mining, the water quantity and quality from the stream section from <br />within T00 feet of the surface coal mining operation shall not be adversely <br />affected, and 3) that the operations reclamation plan provides for the <br />reestablishment of the appropriate riparian vegetation. <br />The operation is in compliance with the requirements of this section. <br />X. Soils - Rules 2.04.9, 2.05.3(5), 2.05.4(2) and 4.06 <br />Baseline soils information is presented in Section 2.04.9 (pages 2.04.9-1 and <br />2.04.9-2) and Exhibits 12 and 13, of the permit application. Maps 19 and 19a <br />show the locations of the soil mapping units. The topsoil handling and <br />management plan is given in Section 2.05.3 (pages 2.05.3-43 through 2.05.3-50) <br />page 2.05.4-5R, and pages 2.05.4-1 OR through 2.05.4-23Ra. Final reclamation <br />plans, including soils information is given for the town load-out in Exhibit <br />23 and for the Williams Fork Strip Pit in Exhibit 24. Topsoil stockpile <br />locations are shown on the structures and renewable resources Map (Map 25). <br />These locations are verbally described on Tables 58 through 62. <br />The permit area has had along history of surface and underground mining <br />resulting in many areas of disturbance where no topsoil was salvaged. In <br />other areas subsoi] and topsoil has been stripped and stockpiled. Some <br />limited areas may be disturbed in the future and in these areas the suitable <br />soil will be stripped and stockpiled. The ma,)ority of the soils which have <br />been salvaged or will be salvaged in the future vary in texture from clay or <br />silty looms to sandy looms. Most of the soils <br />tested were silty clay looms. Most soil material which has been or remains to <br />be stripped is rated as fair with the mayor limiting factor being the somewhat <br />high clay content. Effective rooting depth varies from 20-60 inches, with the <br />most productive soils found in the bottomtand areas. Soil reaction is neutral <br />to slight saline, with the exception of small scattered saline or sodic <br />substrata. These small isolated areas probably formed in place from weathered <br />sodic shales. , <br />In the areas where topsoil is avai]able for replac <br />will vary from 3 to 18 inches (Tables 58 through 62 <br />is suitable for seedbed material.
