• CDOW typically has commented, during previous reviews of mine operations plans, that a continuation of mining activities and other processing-related disturbances would be expected to have a minimal impact on wildlife. CC&V has worked and will continue to work with the CDOW to improve post-mining wildlife habitat. 4.7.1 State and Federal Threatened, Endangered, and Candidate Species The U. S. Fish and Wildlife Service was contacted in June 2007 to determine which threatened, endangered, proposed, and candidate species may be present within the permit boundary and vicinity. The list included bald eagle, Mexican spotted owl, least tern, piping plover, whooping crane, pallid sturgeon, Pawnee montane skipper, and Preble's meadow jumping mouse. CDOW was also contacted and provided a list that included the bald eagle, Mexican spotted owl, least tern, piping, plover, whooping crane, and Preble's meadow jumping mouse. The bald eagle was removed from the Federal threatened and endangered species list in June 2007. None of the other listed species is expected to use the area of the Cresson Project. Appendix 3 in Volume III of this document provides complete details. • 4.8 Soils Previous soil surveys were conducted within the permit area by Nerco Minerals Company in 1984; Newport Minerals in 1985; USDA Natural Resources Conservation Service ("NRCS") in 1993 and 1995; JBR Environmental Consultants in 1996; and Greystone Environmental. Consultants in 1999. Information from these soil studies was consolidated and updated by Arcadis in 2007 using new NRCS soil units and field survey data collected in June 2007. A complete discussion of the evaluation of soil resources within the study area can be found in Baseline Technical Report for Soils and Biological Resources, located in Appendix 3 of Volume III of this document. The results are summarized below. Early soil studies identified three different soil types (Grenadier-like-Unnamed very gravelly loam complex, Quander-Varden complex, and Rogert very gravelly sandy loam). In addition to the named soil groups, other soils or characteristic surface features were mapped in the area. These include mined or disturbed areas, wetland soils, floodplain soils, eroded or flooded soils, and rock outcrops. • Cripple Creek & Victor Gold Mining Company Cresson Project Mine Life Extension 4-17
