• <br /> • SSR <br /> MINING <br /> 7 GROUNDWATER INFORMATION <br /> Information on regional groundwater, including identification of tributary water courses, wells, <br /> springs, stock water ponds, reservoirs, and ditches within two miles of the affected lands <br /> boundary, are shown on Figure G-1 provided in Exhibit G and they are discussed in Exhibit G. <br /> The discussion addresses the regional groundwater system and the transport of groundwater <br /> from the area. The regional geology is shown on Drawing C-7 provided in Exhibit C. The igneous <br /> lithology in the area consists predominantly of phonolite, lapilli breccia, and granodiorite. Much of <br /> the breccia is cemented by a dolomitic carbonate, which, with small pyrite crystals, has replaced <br /> the original mineral fragments and impregnated the other minerals. The volcanic diatreme is <br /> lineated with faults, fractures, veins,joint structures, and underground workings, which have been <br /> drained by tunnels built between 1903 and 1941 to decrease water levels within the Cripple Creek <br /> Mining District (District). The regional groundwater system is intersected by the Carlton Tunnel, <br /> which conveys that regional groundwater six miles to the southwest, to its outlet near the <br /> confluence of Fourmile Creek and Cripple Creek. An evaluation of the current effects of project <br /> activities on regional groundwater was provided in Amendment 11 documentation (December <br /> 2015). The average regional groundwater flow from the Cripple Creek Mining District has not <br /> • increased due to current mining and no increase is anticipated to occur due to proposed <br /> Amendment 14 activities. <br /> 7.1 Groundwater Quality Data <br /> Groundwater quality data are discussed in Exhibit G and supporting data are provided in Appendix <br /> 6 of this Amendment 14 permit. Figures G-1 and G-2 (Exhibit G) show groundwater wells, surface <br /> water bodies and springs filed with the Office of the State Engineer within a two-mile radius of the <br /> affected lands boundary. Groundwater monitoring information includes at least five successive <br /> calendar quarters of data for existing wells, which have been summarized for 29 monitoring wells <br /> in the Cresson Project area (one of which, PGMW-2 has been consistently dry). <br /> • Cripple Creek&Victor Gold Mining Company Exhibit U <br /> Cresson Project Amendment 14 <br /> 12 <br />
