impregnated the other minerals. The volcanic diatreme is lineated with faults, fractures, veins, <br />joint structures, and underground workings, which have been drained by tunnels built between <br />1895 and 1941 to decrease water levels within the District. The regional ground water system is <br />intersected by the Carlton Tunnel, which conveys that regional ground water six miles to the <br />southwest, to its outlet near the confluence of Fourmile Creek and Cripple Creek. An evaluation <br />of the current effects of project activities on ground water is contained in Appendix 2, Volume II <br />of this document. Extension of the current mine areas under the MLE2 is not projected to <br />fundamentally modify the hydrogeologic regime. No increase in the average regional ground <br />water flow rate from the District is occurring due to current mining and no increase is anticipated <br />to occur due to proposed MLE2 development and operation. <br />14.9 Ground Water Quality Data <br />Ground water quality data are discussed in Section 4.6.2 and Appendix 2, Volume II of this <br />document. Drawing G -1 shows wells filed with the Office of the State Engineer within a two - <br />mile radius of the Cresson Project permit boundary. Drawing G -2 shows surface water filings <br />and springs with a water right filed with the Office of the State Engineer within that same two - <br />mile radius. Ground water monitoring information contained in Section 4.6.2 and Appendix 2, <br />Volume II includes at least five successive calendar quarters of data for the existing wells. <br />Ground water data have been summarized for approximately 16 monitoring wells in the Cresson <br />Project area, excluding Grassy Valley. Another 44 wells, four piezometer and 16 boreholds, <br />have been installed and monitored in Grassy Valley to provide overall water quality as discussed <br />in Section 4.6.2 and Volume II, Appendix 2. As noted previously in Section 4.6.2, ground water <br />is not developed for use in this area and is not anticipated to be developed for use in the future in <br />light of the overall lack of ground water in the area. The post- mining land use for the area is <br />livestock grazing and wildlife habitat. <br />14.10 Surface Water Control and Containment Facilities Information <br />Design specifications for the SGVLF and associated drainage control structures, certified by a <br />licensed professional engineer, are summarized above in Sections 7.0 of this Project Description <br />and contained in Appendix 9, Volume V of this document. The High Grade Mill facilities <br />platform design including the liner system is also included in the SGVLF design report in <br />Appendix 9, Volume V. The Storm Water Management Plan for the Cresson Project has been <br />updated by a licenses professional engineer and is contained in Appendix 12, Volume VII. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />14 -13 <br />
