. The area of the proposed ECME lies immediately to the south of the existing East <br />Cresson Mine in an azea that is known locally as the upper Vindicator Valley. This area is <br />within the volcanic diatreme located within the District. <br />Drawings G-1 and G-2 located in Exhibit G in the approved Amendment No. 8 <br />application provide some background and are listed here for reference purposes. <br />4.6.1.1 Surface Water <br />There is generally no surface water in the area of the proposed ECME except during <br />snowmelt or following heavy precipitation events. The azea has been previously <br />disturbed through historic mining activities. There aze no perennial or intermittent <br />streams located in this azea. <br />The Vindicator Valley drains to what is known locally as Theresa Gulch, which is in the <br />upper reaches of the Wilson Creek watershed. Theresa Gulch is ephemeral to <br />intermittent. <br />4.6.1.2 Ground Water <br />Due to the volcanic diatreme in the District and the historic drainage tunnels, the azea is <br />unsaturated and does not contain significant quantities of ground water. Present mining <br />• activity by CC&V has not encountered ground water other than local perched water <br />tables that tend to contain a limited amount of water. Deep drill holes within the volcanic <br />diatreme [end to be dry or have low yields. There has been no ground water encountered <br />in the East Cresson Mine, immediately to the north of the proposed ECME. In addition, <br />drill holes in the area of the ECME have been generally dry or have encountered only <br />small amounts of perched water. As with the East Cresson Mine, no ground water is <br />anticipated to be encountered in the ECME. <br />Wildlife (4.6.21; Soils (4.6.3): and Vegetation (4.6.4) <br />The ECME is du•ectly south of the existing East Cresson Mine. Notwithstanding the <br />investigations completed as part of prior permitting activities, CC&V decided to engage <br />Greystone Environmental Consultants Inc. ("Greystone") to provide an updated <br />environmental report for wildlife (threatened, endangered, and sensitive species), soils, <br />and vegetation in the general azea of the proposed ECME. This report was generated <br />following a review of the Amendment No. 8 reports and a field investigation conducted <br />in March 2004, during a period when the ground was open and not snow covered. <br />The conclusions in the original Greystone Report and as confirmed by the updated report <br />are listed below: <br /> <br />
