A more detailed review of the soils information on the JD -6 mine permit site is provided <br />in Exhibit T — EPP. <br />Vegetation Information <br />The pinon juniper woodland at the site consists of approximately 30% to 50% pinon pine, <br />and 50% to 70% Utah juniper. Most stands are not more than 20 feet tall, although some <br />individuals may reach 35 feet. <br />The tree canopy covers about 25% to 30 %, understory covers about 10 %, and the <br />remaining ground is bare. <br />The average annual production of understory vegetation is about 400 to 500 pounds per <br />acre. <br />The pinon juniper woodland typically corresponds to soil map unit symbols 23- Bodot, <br />dry -Ustic Torriorthents complex and 75- Pinon- Bowdish- Progresso loams. <br />The sagebrush park areas have an average ground cover of 40% with the remaining soil <br />bare. The composition of the vegetation in these areas is shown in Table J -2, taken from <br />the Web Soil Survey. <br />The grasses range in height from six inches to 24 inches. The height of the sagebrush <br />ranges from one foot to four feet. <br />The average annual production is 1,100 pounds per acre. <br />The sagebrush park areas typically correspond to soil map unit 60- Monogram loam. <br />A more detailed review of the vegetation on the JD -6 mine permit site is provided in <br />Exhibit T — EPP. <br />Water Information <br />There are no surface waters located on the proposed affected areas of the JD -6 lease tract, <br />or on the Mineral Joe 17, Mineral Joe 18, or Mineral Joe 19 claims. <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 />B -2 <br />
