2.04.9 Soils Resource Information <br />Rule 2.04.9 (1)(a -e) for Lord & Associates Soil Investigation follows: <br />INTRODUCTION <br />The purpose of this inventory is to satisfy the requirements of DRMS for soils <br />information for environmental permit applications for the McClane Canyon Mine. <br />Soils information in the inventory includes mapping of disturbed areas and areas <br />to be disturbed; characterization and classification of major soil series; identification of <br />soil sampling sites; chemical and physical analysis of major soil series; evaluation of <br />major series for topsoil resources; and present and potential uses of the permit area <br />soils. The taxonomic families for the principal permit area soils are included. <br />METHODOLOGY <br />The field work included refinement of R.V. Lord and Associates mapping with <br />emphasis upon the collection of site-specific data (Figure 4.4.1, Soil Inventory Map). <br />Mapping included field checking on foot with hand augers. The mapping approximates <br />an order I or II level of intensity in areas to be affected and order III in the remainder of <br />the area. The majority of the soils mapped are classified to the series level; some are <br />classified only to the subgroup level (See Figure 4.4.1). <br />Collection of site-specific information included the excavation, description, <br />sampling and analysis of major soils series, man-made fill and other disturbed <br />materials. Soil map units were refined to include approximate percentages and types of <br />inclusions. Sampled pedons were located on the soil map. Mapping, sampling, and <br />detailed soil descriptions are in accordance with the National Cooperative Surveys <br />(USDA -Soil survey staff, 1975; USDA -Soil Survey Staff, 1955). Soil analysis was <br />conducted by F & L Labs in Fort Collins, Colorado. <br />From this information and site specific data, the major soils to be affected in the <br />study area were evaluated as a source of material available for reclamation. The <br />present and potential uses of the major soils were evaluated for croplands, pasture <br />lands, and range lands. <br />SOIL SERIES DESCRIPTIONS <br />GLENDIVE SERIES <br />The Glendive series consists of deep, medium textured, well -drained soils. These <br />soils formed in stratified alluvium. Elevation range is 5,250 to 5,450 feet. Annual <br />precipitation is about 10 inches. The mean annual soil temperature ranges from 400 to <br />470 F, and the frost free period is 105 to 135 days. The vegetation is a greasewood - <br />shrubland community. <br />PR -02 2.04-34 10/12 <br />
