" In keeping with this resolution, Cripple Creek & Victor Gold Mining Company (CC&V) • has prepared this technical revision of the Amendment No. 9 submittal to update the planning in the Schist Island portion of the North Cresson mining area. Mining activities scheduled in Schist Island portion of North Cresson mining area for approximately 2015 and 2016 (see revised drawing C-5) have been revised to provide for additional overburden backfill placement in the area of the Schist island portion of the North Cresson Mine that was previously shown as a remaining highwall within the City of Cripple Creek view shed. This additional overburden placement during mining will provide for an additional 17.5 acres of surface mine reclamation in this portion of the North Cresson mine. (Total reclaimed acres for this portion of the North Cresson will be adjusted from approximately 92 acres to approximately 109.5 acres.) This additional overburden will be graded to create an additional reclaimable landform that will be blended to the surrounding topography as shown in the revised post-mining topography map (see revised drawing F-1). These regraded slopes will then be covered with a minimum of six inches of growth medium and reseeded in accordance with the approved reclamation plan. Reclamation surety costs to complete this additional regrading, growth medium placement, and revegetation have been included in the updated reclamation surely estimate included in this revised plan. Several minor changes to the Amendment No. 9 approval are needed to complete this revision and are included with this application. A summary of the updated information is provided below:
