• SSR MINING cubic yards of growth medium will be required. It is estimated that approximately 3.4 million cubic yards of growth medium are available from the existing and future development areas for the completion of reclamation, indicating that there is more than sufficient volume of suitable growth medium available to accomplish the proposed reclamation. 2.3 Growth Medium Replacement Growth medium generally will be transported from the closest growth medium storage area to the area being reclaimed or, where possible, will come directly from active salvage operations to concurrent reclamation areas. In general, a minimum of six inches of growth medium are intended to be replaced at reclamation sites, which have been used in the financial warranty cost estimates discussed in Exhibit L of this application. The growth medium will be spread using dozers. CC&V has accounted for three-dimensional topography in its closure estimate. If the mine is developed to full build out described in this amendment there will be approximately 4,460 three-dimensional acres. Growth medium will not be replaced on highwall benches within the mining areas due to accessibility issues. Growth medium will be placed on accessible haul roads and pit floors. • 2.4 Revegetation After growth medium placement and grading, soil sampling may be performed to assess the potential need for use of additional soil amendments to enhance revegetation efforts. Fertilizer and other appropriate soil amendments will be broadcast on the reclamation areas before, during or after growth medium placement depending on site specific conditions and constraints (e.g., accessibility, moisture content, application rate). Application of the seed mix presented in Table E-1 will be broadcast, drilled, or hydro-seeded onto the placed growth medium. Table E-1 provides a list of preferred species of seeds and a list of alternative species seeds in the event the preferred seed is not commercially available. The application rate of the seed mix will be approximately 25 pounds of pure live seed (PLS) per acre. The seed mix may be further incorporated into the growth medium covered using a rangeland harrow, slope chain, or equivalent equipment, as necessary and feasible. All seeded areas will be mulched either with straw mulch or wood fiber mulch depending on application method. Hydro- mulch or other surface treatments may be used to facilitate the revegetation efforts in steep or high-profile areas and generally will be applied at a rate of 2,000 pounds per acre of wood fiber hydro-mulch. A combination of broadcasting of the seed mix presented in Table E-1 followed by • Cripple Creek&Victor Gold Mining Company Exhibit E Cresson Project Amendment 14 3
