• Methodology <br />Tasks performed to accomplish project objectives included: <br />• review of existing soils information <br />• detailed field mapping of soils <br />• soil sampling and proftle description <br />• evaluation of soils for reclamation potential <br />The methodology used during the soil surveys followed standard techniques and procedures of the <br />National Cooperative Soil Survey. <br />In connection with the 1988, 1996, and 1998 studies, samples were collected in the field and analyzed <br />in the laboratory in accordance with CDMG-approved procedures for topsoil analyses as outlined in Table <br />2.04.9-1. The information presented in Table 2.04.9-1 is a synthesis of material from the approved <br />scope-of-work, InterMountain Laboratories (IML's) and Colorado State University Soil Lab standard <br />procedures for soil analysis. Sample site locations were selected to most accurately represent the <br />. sampled soil series and to provide for adequate sample site distribution across the projected disturbance <br />areas. Transition zones between map units, road edges, fence rows, or previously disturbed areas were <br />avoided. Representative profiles were selected on the basis of medial characteristics for physical and <br />chemical soil characteristics, parent material, landscape position, and vegetation. The majorsoil horizons <br />(A, E, B, and C) were separately described, sampled, and analyzed. Portions of paralithic material (Cr), <br />if present, were also described, sampled, and analyzed for characterization purposes and possible <br />subsequent use as a topsoil substitute 'rf needed. <br />Surface and subsoil horizons (A and B horizons) were sampled to represent no greater than about six <br />inches of soil material per sample. Sub-horizons (81, B2, etc.), greater than three inches within any <br />major horizon, were separately sampled and analyzed. In the substratum (C horizon), natural horizons <br />(Ci , C2, and so forth) were subdivided such that individual samples did not represent greaterthan about <br />18 inches of soil material. <br />• (REVISED z/oo) 2.04.9-5 <br />
