RULE 2 PERMITS <br />The Lower Wilson mining area contains several deep soils with suitable topsoil that are on mostly gently <br />sloping to moderately sloping areas. These soils include Adderton sandy loam (Map Unit A), Cochetopa <br />sandy loam (Map Unit B), and Silas sandy loam (Map Unit S), with recommended salvage depths of <br />suitable soil of 18 inches, 18 inches, and 48 inches, respectively. <br />Three other deep soils (Campspass channery sandy clay loam, Rhone loam and Lamphier sandy loam) <br />also have thick deposits of suitable soil, with 12 inches, 24 inches, and 36 inches, respectively, of <br />recommended salvageable soil. A portion of the areas Campspass (Map Unit D), Rhone (Map Units C <br />and D), and Lamphier (Map Unit E) soils are mapped on have slopes greater than 40 percent. The very <br />steeply sloping portions (>40% slopes) are estimated to be about 20 to 25% of the proposed disturbed <br />area and are located along very steep portions of the valley sideslopes of "unnamed" drainage in the main <br />area of the potential disturbed area. <br />In addition, two other soils in the potential disturbed area have suitable soils. Waybe stony sandy loam <br />and Danavore channery loam (both in Map Unit F) have approximately 6 inches of suitable soil. These <br />are shallow and moderately deep soils, respectively, and primarily are on moderately sloping areas. <br />Finally, a very small portion of the proposed disturbed area is Disturbed Land (Map Unit DL). This <br />accounts for only 2.4 acres, and no soil is available for salvage from this area. <br />According to the suitable salvage depths of the encountered soils, it is apparent that a sufficient volume of <br />suitable soil exists in the proposed mining area to ensure subsequent successful reclamation, assuming all <br />recommended suitable soil is salvaged and best -management practices are employed during reclamation <br />activities. Salvage of soils on slopes greater than 40% may be impractical in this area; however, a <br />sufficient volume of suitable soil should still be available for successful reclamation. The actual proposed <br />disturbed area will be determined by the mine plan for the area. The weight -average calculation of <br />suitable soil recommended for salvage across the area and the resulting total cubic yards of salvageable <br />soil will be determined after the mine plan is developed for the area. <br />Map Unit Suitability Evaluation, Salvage Depths, and Soil Volumes — Lower Wilson North Haul Road <br />Area <br />The Lower Wilson North Haul Road soils study area is approximately 21 acres. Four deep soil pits <br />(LW17, LW18, LW19, and LW20) were dug by backhoe within the proposed north haul road study area. <br />Soils were described at all four sites, and two representative sites (LW17 for Yamo fine sandy loam and <br />LW20 for Battlement fine sandy loam) were sampled for laboratory analysis. The corridor crosses the <br />two deep soils, Battlement fine sandy loam (Map Unit 10) and Yamo fine sandy loam (Map Unit 216), as <br />well as a small portion of the Wilson Creek drainage channel (Map Unit WC). Both Battlement and <br />Yamo fine sandy loams have approximately 18 inches of suitable soil available for salvage. The Wilson <br />Creek drainage is a perennial stream and the drainage channel does not have available soil for salvage. <br />A sufficient volume of suitable soil exists along the proposed Lower Wilson North Haul Road corridor to <br />ensure subsequent successful reclamation assuming all recommended suitable soil is salvaged and best - <br />management practices are employed during reclamation activities. The expected disturbed area will be <br />determined by the design of the haul road. The weight -average calculation of suitable soil recommended <br />for salvage across the area and the resulting total cubic yards of salvageable soil will be determined after <br />the mine plan is developed and the haul road design is completed. <br />2.04.10 Vegetation Information <br />The objective of this section is to meet the requirements of Rule 2.04. 10 et seq. by describing the general <br />vegetation community types and distribution within the permit boundary revision area and providing <br />South Taylor/Lower Wilson — Rule 2, Page 37 Revision Date: 11 / 18/16 <br />Revision No.: MR -163 <br />
