RULE 2 PERMITS • Texture, clay >40% • Selenium >0.1 ppm • Boron >5 ppm • Coarse fragments >35% Soil Resource Assessment Results Eleven soil map units were delineated in the Lower Wilson soil survey areas including small areas of the Wilson Creek road corridor (Map Unit DL) and the Wilson Creek drainage channel (Map Unit WC). The following is a list of soil map units for the Lower Wilson Mine Area (595 acres) and the Lower Wilson North Haul Road Area (21 acres): Lower Wilson Mine Area Map Unit A: Adderton sandy loam, 2 to 10% slopes Map Unit B: Cochetopa sandy loam, 4 to 25% slopes Map Unit C: Rhone loam, 25 to 65% slopes Map Unit D: Campspass — Rhone Complex, 25 to 65% slopes Map Unit E: Lamphier sandy loam, 25 to 65% slopes Map Unit F: Danavore — Waybe — Rock Outcrop Complex, 6 to 45% slopes Map Unit S: Silas sandy loam, 2 to 15% slopes Map Unit DL: Disturbed Land Lower Wilson North Haul Road Area Map Unit 10: Battlement fine sandy loam, 2 to 10% slopes Map Unit 216: Yamo fine sandy loam, 4 to 15% slopes Map Unit WC: Wilson Creek drainage Map Unit DL: Disturbed Land The distribution and extent of map units in the survey areas are presented on Map 5C. The maps were compiled on a topographic map base at a scale of 1"=500'. The soils maps contain a map unit legend and all map unit delineation lines. Twenty soil description/sample sites are also located on the maps. The soil delineations have been digitized into the electronic file for map display and acreage determination by map unit. A summary of various map unit descriptive information is presented in Table 2.04.9-9 and Table 2.04.9- 10. The information for each map unit includes: ■ Map unit symbols • Map unit names ■ Slope ranges ■ Acreage and percent of total ■ Brief soil profile description of each soil type ■ Terrain and vegetation ■ Parent material type ■ Land Capability Class ■ Range/Woodland Site South Taylor/Lower Wilson — Rule 2.
