• on Drawings C-5 and F-l. The backfill will be truck dumped in lifts of varying heights depending on the location of haul roads in that portion of the mine area. The backfilled material will be placed at an approximate 2H:1 V slope and is not expected to approach the elevation of the natural ground surface, but encompasses significantly more of the mine area than the previously approved backfill under Amendment No. 8. This backfill area will not be regraded or receive soil placement and revegetation. No backfill will be placed in the southern portion of Main Cresson Mine area (the South Cresson portion) or in the Globe Hill portion of the North Cresson Mine area. The final configuration of these areas will remain as defined by the mining operation. Growth medium will be redistributed in the unbackfilled bottom portions of the mine to a depth of approximately six inches or less depending on accessibility and availability of material. The Schist Island portion of the North Cresson Mine area will be backfilled to promote free drainage to the surrounding ground surface, to cover highwalls that remain followin mining activities and to blend with the SGOSA. As such, the information provided above related to reclamation of SGOSA includes the backfilled North Cresson Mine area. • The East Cresson Mine area is expected to be backfilled to promote free drainage to the surrounding natural ground surface as previously approved for Amendment No. 8. This backfilling will include the WHEX portion of the East Cresson to be mined as part of the MLE. Backfilling will be accomplished by end-dumping the material in "lifts" that range in height, depending on the logistics of truck hauling, the geographic locations relative to the mines, and overburden removal scheduling. It is anticipated that this area will be backfilled to an elevation and shape that will promote free drainage to the surrounding surface and graded to blend with the surrounding topography including the reclaimed topography of the ECOSA. Growth medium will be used to cover the overburden placed as backfill. Section 11.2 discusses that approximately six inches of growth medium is expected to be available to cover the reclamation areas. Other material containing fines will be used if stockpiled growth medium is not available. The growth medium will be sampled to determine the need for amendments. Vegetation will be established according to the revegetation procedures presented in Section 11.3. Cripple Creek & Victor Gold Mining Company Cresson Project Mine Life Extension 11-13 •
