7. Soils and Geomorphology —1996 (PR -04) <br />The study area included the Garvey and Burbridge properties located within the original 1988 <br />survey. This survey updated map unit delineations and provided detailed topsoil salvage depths <br />for the above properties. <br />8. Soils and Geomorphology —1998 (PR -05) <br />The study area included the Morgan property located within the original 1988 survey and <br />additional areas north of BB Road that were not surveyed in 1998. This survey updated map unit <br />delineations and provided detailed topsoil salvage depths on the Morgan property as well as <br />detailed baseline soil information on properties located north of BB Road. The geology and <br />geomorphology are similar to that located in the original 1988 survey. <br />9. 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 profile description <br />• evaluation of soils for reclamation potential <br />The methodology used during the soil surveys followed standard techniques and procedures of <br />the National Cooperative Soil Survey. <br />In connection with the 1988, 1996, and 1998 studies, samples were collected in the field and <br />analyzed in the laboratory in accordance with CDMG-approved procedures for topsoil analyses <br />as outlined in Table 2.04.9-1. The information presented in Table 2.04.9-1 is a synthesis of <br />material from the approved scope -of -work, InterMountain Laboratories (IML's) and Colorado <br />State University Soil Lab standard procedures for soil analysis. Sample site locations were <br />selected to most accurately represent the sampled soil series and to provide for adequate sample <br />site distribution across the projected disturbance areas. Transition zones between map units, road <br />edges, fence rows, or previously disturbed areas were avoided. Representative profiles were <br />selected on the basis of medial characteristics for physical and chemical soil characteristics, <br />parent material, landscape position, and vegetation. The major soil horizons (A, B, and C) were <br />separately described, sampled, and analyzed. Portions of paralithic material (Cr), if present, were <br />also described, sampled, and analyzed for characterization purposes and possible subsequent use <br />as a topsoil substitute if needed. <br />January 2016 (TR -70) 2.04.9-4 <br />
