Cripple Creek & Victor Gold Mining Company Exhibit E Cresson Project Amendment 13 15 1.5.6 Ancillary Support Facilities Ancillary support facilities, including the crusher facilities and associated structures, the HG Mill facilities, both ADR facilities, the fire assay laboratory, the overland conveyor, the load out bin (LOB), the Ironclad facilities (maintenance-warehouse-office), and the associated utilities, monitoring systems, the Projects Offices facilities, fuel island, radio towers, associated tanks, pipelines and other structures and mobile equipment will be removed or reclaimed in the same manner as previously approved. In consultation with appropriate representatives of Teller County, CC&V may later propose to retain and use some of the existing facilities; however, it is not possible to specify which of those existing facilities could remain at the present time. Once mining operations have ceased, portable equipment within the processing areas will be removed. Buildings and foundations either will be demolished and removed from the site or buried in place to a depth that will allow for reclamation procedures as discussed in Section 1.4. The areas of land disturbed by these activities will be regraded, covered with suitable growth medium, and reclaimed. Chemicals and reagents will be removed, along with empty containers and disposed of appropriately at off-site facilities. Facilities will be dismantled and salvaged, as appropriate, after mining and processing operations are completed. Many of the materials in these facilities have salvage value; however, the computations for the financial warranty in Exhibit L do not assume credit for that salvage value. Following demolition and salvage, remaining debris for burial will be removed to an OSA, one of the mine areas backfill sites, or to the ESP footprint area, or will be buried in-place (e.g., concrete foundations). These areas will be graded, and growth medium applied to the extent available prior to reclamation. 1.5.7 Closure Stormwater The previous closure stormwater analysis was updated to include the VLF2 Phase 3 expansion, specifically, the VLF and OSA closure stormwater analysis has been updated and is included in Appendix 3. Previous analyses included closure stormwater analysis for each VLF and OSA. Modeled peak run off was calculated for at least the 100-year/24-hour storm event. Diversion channels were designed around the facilities to convey water off the facilities. Additionally, channels on the facilities benches will be constructed ever 150 vertical feet to convey water to the diversion channels. All channels have side slopes of 2.5H:1V and were designed as either triangular or trapezoidal cross sections and a minimum of 1 foot of freeboard. Details of the updated VLF2 Phase 3 closure stormwater analysis can be found in the VLF2 Phase 3 Design
