The rating class for this soil type is poor, as shown on the attached Soil Interpretation <br />Sheet. Previous experience reclaiming mine dumps in this area indicates that spreading <br />at least a minimal amount of these soils over the re- contoured mine waste provides a <br />reasonable environment to sustain re- vegetation efforts. <br />The existing access road and vent hole site consistsof two different soil types. The <br />majority of the soil in this area consists of map unit symbol 75- Piiion- Bowdish- Progresso <br />loams with a typical profile being as follows: <br />0 -5 inches: Loam <br />5 -16 inches: Gravelly Loam <br />16 -20 inches: Unweathered bedrock <br />The rating class for this soil type is poor, as shown on the attached Soil Interpretation <br />Sheet. Previous experience reclaiming mine dumps in this area indicates that spreading <br />at least a minimal amount of these soils over the re- contoured mine waste provides a <br />reasonable environment to sustain re- vegetation efforts. <br />The other soil type in this existing access road and vent hole site area consists of map unit <br />symbol 60-Monogram Loam with a typical profile being as follows: <br />0 -3 inches: Loam <br />3 -14 inches: Loam <br />14 -28 inches: Loam <br />28 -60 inches: Sandy clay loam <br />The rating class for this soil type is fair, as shown on the attached Soil Interpretation <br />Sheet. Previous experience reclaiming mine dumps in this area indicates that spreading <br />at least a minimal amount of these soils over the re- contoured mine waste provides a <br />reasonable environment to sustain re- vegetation efforts. <br />A more detailed review of the soils on the Mineral Joe permit site is provided in Exhibit <br />T — EPP. <br />Water Information <br />There are no surface waters located on the proposed affected areas of the Mineral Joe <br />claims held by Cotter. <br />Exploration drilling has indicated that some perched water tables may be encountered in <br />the noncontiguous, isolated sandstone bodies in the basal unit of the Brushy Basin <br />Member of the Morrison formation, and below the ore horizon in the top rim of the Salt <br />Wash Member of the Morrison Formation. These waters lie approximately 120 to 270 <br />feet above the Entrada Formation, the nearest aquifer. If water flows are encountered <br />during mining operations Cotter will comply with all applicable federal and Colorado <br />water laws and regulations as to water rights and discharge permits. If water flows are <br />encountered during mining operations, and it is more than can be evaporated in a lined <br />evaporation pond, Cotter will apply for a National Pollutant Discharge Elimination <br />System (NPDES) permit from the Water Quality Control Division of the Colorado <br />Department of Public Health and Environment. <br />Surface runoff from the affected areas will be addressed in Section T, the Environmental <br />Protection Plan. <br />B -2 <br />
