• Power will be provided via an over head transmission line consisting of two separate <br />circuits. One circuit will be designated to the pumps associated with the VLF and the <br />other will be dedicated to the crushing circuit. In addition, three new generators will be <br />added to the 3 existing back-up generators to operate the pumps during a power outage. <br />In the event of a substantial cyanide spill, the mine has the capability to destruct 21 <br />million gallons of cyanide solution within the ESP, as approved under Amendment No. 8. <br />A monitoring program is presented in Section 10.0 of the Project Description. Additional <br />VLF facility designs including capacity, redundancies, and back-up systems are included <br />in Section 6.0 of the Project Description. The emergency response measures, including <br />reporting, are contained in Appendix 9, Volume VII of this document. <br />13.8 Ground Water Information <br />Information on regional ground water, including identification of tributary water courses, <br />wells, springs, stock water ponds, reservoirs, and ditches within two miles of the Cresson <br />Project, inclusive of the MLE, are shown on Drawing G-1 and discussed previously in <br />Section 4.6.1. The discussion addresses the regional ground water system and the <br />• transport of ground water from the area. The regional geology is shown on Drawing C-7 <br />and geology beneath project facilities is discussed above in Section 4.4. The igneous <br />lithologies in the area consist predominantly of phonolite, lapilli breccia and granodiorite. <br />Much of the breccia is cemented by a dolomitic carbonate, which, with small pyrite <br />crystals, has replaced the original mineral fragments and impregnated the other minerals. <br />The volcanic diatreme is lineated with faults, fractures, veins, joint structures, and <br />underground workings, which have been drained by tunnels built between 1895 and 1941 <br />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 <br />the southwest, to its outlet near the confluence of Fourmile Creek and Cripple Creek. An <br />evaluation of the effects of project activities on ground water is contained in Appendix 2, <br />Volume II of this document. Extension of the current mine areas under the MLE is not <br />projected to fundamentally modify the hydrogeologic regime. No increase in the average <br />regional ground water flow rate from the District is occurring due to current mining and <br />no increased is anticipated to occur due to proposed MLE mining. <br />13.9 Ground Water Quality Data <br />Ground water quality data are discussed in Section 4.6.2 and Appendix 2, Volume II of <br />this document.
