• 8.4 Power Supply <br />Electrical power to all of the mine area is supplied by Aquila. Aquila has furnished power <br />lines to its substation located near the crusher facility. A new substation, constructed, <br />owned, and maintained by Aquila, will be constructed just south of Arequa Gulch and <br />across Highway 67 as shown on Drawing C-3. The existing substation then will be closed <br />and removed by Aquila. The new substation will supply power to the local area (e.g., <br />Cripple Creek, Victor, Goldfield, etc) as well as CC&V's operations. The anticipated <br />location of powerlines is shown on Drawing C-3. Note that actual locations may vary <br />from those shown due to site specific conditions and field constraints during construction. <br />Since the startup of the Cresson Project, backup or "standby" diesel-powered generators <br />have powered the pump systems at the VLF during the few short line power outages. This <br />back-up system has worked effectively and adequate back-up power will be available <br />through a total of 6 (up from 3) back-up diesel generators for the extended activities of <br />the MLE. In effect, this reduces the possibility that there would be the 12-hour draindown <br />period used in the design of the PSSAs. <br />8.5 Water Supply <br />• Currently, fresh water for on-site use is purchased from various sources based on <br />contractual arrangement and delivered primarily from the City of Victor's system. Water <br />is pumped from the City of Victor's Altman Pump Station (located on Beaver Creek) and <br />supplied to the Cresson Project, or by gravity from a surface reservoir system located <br />further upstream. The water supplied is untreated (chlorination is used when supplied for <br />domestic purposes in the Victor public water supply system). A copy of the agreement <br />with the City of Victor is included as Appendix 9 of this document. CC&V has a back-up <br />water supply via an agreement with the City of Colorado Springs. A copy of that <br />agreement also is included in Appendix 2. Supplies for domestic use (i.e., drinking) on <br />site are derived from commercially-provided bottled water. <br />Water is used in the ore beneficiation circuit, for suppression of fugitive dust, drilling, <br />laboratory, sanitary facilities, and for various miscellaneous associated uses such as <br />vehicle washing and applying hydromulch for revegetation. The primary use of water is <br />in the VLF facilities. Section 6.0 contains a discussion of water use on the VLF as well as <br />a water balance for the VLF. <br />L <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension <br />8-2
