RULE 2 PERMITS <br />A summary of various soils interpretative information is presented in Table 2.04.9-11. The information <br />for each soil series includes: <br />• Soil series name and map unit symbol <br />■ Texture of the soil control section <br />■ Soil depth class <br />• Effective rooting depth <br />■ Internal drainage class <br />■ Permeability class <br />■ Available water holding capacity <br />■ Rate of surface runoff <br />■ Typical reaction class <br />■ Wind erodibility group <br />■ Water erosion hazard <br />■ "K" factor <br />■ Hydrologic group <br />■ Understory production (lbs/ac/yr) <br />• Organic matter percent of "A" horizon <br />■ Thickness of "A" horizon <br />A listing ofNRCS soil taxonomic information is presented in Table 2.04.9-12. The information for each <br />soil series includes: <br />■ Soil series classification <br />■ Type location, including county and state <br />■ Date of most recent official soil series description <br />A summary of information relating to soil suitability and recommended salvage depths is provided in <br />Table 2.04.9-13. The information for each map unit and soil series includes: <br />■ Map unit symbol and name <br />■ Acreage of each map unit in the disturbed area <br />■ Soil sample location numbers <br />■ Total soil depth <br />■ Total salvage depth <br />■ Recommended topsoil/subsoil salvage depth <br />■ Limitations to deeper salvage <br />Soils laboratory data for the forty soil samples, collected from eleven soil profiles, is presented in Table <br />2.04.9-14. <br />Map Unit Suitability Evaluation, Salvage Depths, and Soil Volumes — Lower Wilson Mine Area <br />Soil suitability and salvage depth was evaluated for all soil horizons of each soil series in each map unit in <br />the Lower Wilson mining area. As stated above, results of that evaluation are presented in Table 2.04.9- <br />12. The Lower Wilson mining area contains mostly deep soils with sufficient quantities of suitable soil <br />available for salvage. Seven map units were identified within the disturbed area associated with the <br />Lower Wilson Mine Area. A total of 16 soil profiles were fully described in the Lower Wilson mining <br />area. Thirty soil samples were collected from 9 of the excavated soil profiles. Soils description/sample <br />locations are shown on Map 5B. <br />South Taylor/Lower Wilson — Rule 2, Page 36 Revision Date: 4/7/17 <br />Revision No.: RN -07 <br />
