i Spills to land that exceed the RQ volume criterion in any24-hour period must be reported to external agencies in accordance with this SRP (see section 6 for more details). A representative of the Environmental Resources Department will complete external notification, if and when necessa 'ry. • Table 1 lists reportable quantities of chem icals that require external spill reporting. MSDS's for these products are in Appendix B. I 1.2 General Location of CC&V Operations ~ i CC&V's Cresson Project operations are located within the Cripple Creek Mining District; generally between the City of Victor and the City of Cripple Creek. The permitted mining operations occ~ r within one to two miles of either city. For reporting purposes the CC&V site location, expressed as latitude and longitudeat the Security Office is: Latitude is 38° 43' 37" North and Longitude 105° 09' 27" West. I The Project area, in southern Teller County, is accessible by Colorado State Highway 67 between Victor and Cripple Creek, Teller County Road 81 from State Highway 67 in Gillette Flats through Victor, from Teller County 82/83 (Cameron Road) and from State Highway 67 (north of Cripple Creek). Figure 1 shows the general location of the site. 1.3 General Description of Mine Facilities The mine facilities at the Cresson Project are shown on Figure 2. CC&V's gold mining activities use conventional surface mining and ore crushing methods. Mineral recovery is accomplished by "heap" leaching with dilute cyanide solutions, followed by carbon adsorption, then desorption, and electrowinning. Leach pads and ponds containing cyanide solutions are double and triple lined with the incorporation of leak detection systems. The only operating leach facility, the Valley Leach Facility ("VLF"), is double-lined in areas where solution is not stored and triple lined where solution is collected and temporarily stored. The pad systems are designed to contain the normal operating solution level, total heap drain-down, "wet season" precipitation, and the 100-year, 24-hour storm event. Mineral Beneficiation Facilities (also known as Adsorption Desorption Recovery or "ADR") are • constructed and operated to provide containment and collection of any spills within the ADR building. The VLF and ADR are "non-discharging" (zero-discharge) facilities. The ADR facility uses hydrochloric acid and sodium hydroxide in addition to sodium cyanide. Major equipment maintenance is performed at the Ironclad Shop/Warehouse and the New Truck Shop.. Minor equipment maintenance operations and vehicle re-fueling occurs in selected field locations within the mining operation. Maintenance of mechanical equipment associated with the crushers takes place at the- Primary and Secondary Crushers. The principal petroleum products used at the crushers are lubricants. Lime is stored and fed to the crushed ore at the Secondary Crushers. 1.4 General Description of Site Security at CC&V Operations Cripple Creek and Victor Gold Mining properties are subject to the following general security measures: (1) a substantial portion of the property is fenced with barbed wire with chain link or wire mesh and barbed wire; (2) entrances to mine property are gated and locked; (3) the permit boundaries are staked and warning signs are posted; (4) most onsite facilities are staffed on all operating shifts, so that there is a company supervisor onsite 24 hours a day, 7 days a week (24/7); (5) security guards are on duty 24/7 at the ADR facility main entrance from Highway 67; (6) the Ironclad Facility is staffed 24/7 with mechanics and a supervisor; and (7) key portions of the site are lighted during the night-time hours. Individual facility security measures (barricades, poles, locked buildings, etc.) are discussed in other sections of this plan, as appropriate.
