Soil Samplin and Profile Description. All soil taxonomic units appearing in the soil • <br />survey legend and occurring within the projected disturbance area were described and <br />characterized. Soil sample sites were located primarily within the anticipated <br />disturbance area. One sample per taxonomic unit adequately characterized each map unit, <br />and followed or exceeded sample intensities recommended by PCC and CMLRD. <br />Samples were collected in the field and analyzed in the laboratory in accordance with <br />CMLRD-approved procedures for topsoil analyses as outlined in Table 9-6-1. The <br />information presented in Table 9-6-1 is a synthesis of material from the approved <br />scope-of-work and Peabody Central Laboratory (PCL) standard procedures for topsoil <br />analysis. Sample site locations were selected to most accurately represent the sampled <br />soil series and to provide for adequate sample site distribution across the projected <br />disturbance areas. Transition zones between map units, road edges, fence rows, or <br />previously disturbed areas were avoided. Representative profiles were selected on the <br />basis of medial characteristics for physical and chemical soil characteristics, parent <br />material, landscape position, and vegetation. The major soil horizons (A, E, B, and C) <br />were separately described, sampled, and analyzed. Portions of paralithic material (Cr), <br />if present, were also described, sampled, and analyzed for characterization purposes and • <br />possible subsequent use as a topsoil substitute if needed. <br />Surface horizons (A1, A2, etc.), were sampled to represent no greater than about 6 to 12 <br />inches of soil material per sample. In the subsoil and substratum (B and C horizons), <br />natural horizons (Bw, Bt, C7, C2, and so forth) were subdivided such that individual <br />samples did not represent greater than about 18 to 24 inches of soil material. <br />Physical and, where possible, chemical properties of each horizon within the sampled <br />profile were described and recorded in the field on standard SCS "232" soil description <br />forms. These properties included: <br />o depth and thickness of horizons <br />o relative position of soil horizons <br />o type and nature of horizon boundaries <br />o color (moist) of horizons <br />o texture (fine earth fraction) <br />o coarse fragment content (type - gravel, cobble, sandstone channer, etc.; size • <br />(2mm-3", 3"-10", greater than 10"); and percent (@) by volume, if significant) <br />9-6-11 Revised 05/16/88 <br />
