north and northwestern portion of the SGOSA. Under MLE2, additional areas of the <br />SGOSA will require relocation as shown on Drawing C -4a. The relocation of additional <br />SGOSA material under MLE2 is discussed in Section 5.7.1. When development is <br />completed in the Schist Island portion of the North Cresson Mine area, the mine area will <br />be backfilled and blended with the SGOSA as shown on Figure F -1. Once the maximum <br />footprint has been reached, the outslopes will be graded to final overall grades of <br />approximately 2.5H:1 V. Sections of varying steepness will be formed within this overall <br />outslope to generate irregular landforms. The approved final elevation of the SGOSA <br />does not change with MLE2 and is approximately 10,600 feet as approved for MLE. <br />Benches on the order of 8 -10 feet wide may be retained along the reclaimed slopes at <br />intervals that both reduce the length of "run" (flow path length) of storm water runoff and <br />provide access for reclamation activities. These benches also may be used to capture and <br />convey storm water runoff to other areas. <br />Growth media salvaged from MLE2 areas, along with the material already stockpiled, <br />will allow placement of about six inches of growth medium on the SGOSA. The soil <br />may be sampled to determine the requirements for soil amendments. Vegetation will be <br />established in accordance with the procedures outlined above in Section 12.3. <br />As approved in previous applications, it is anticipated that some slopes may be plated <br />with coarse rock for storm water runoff protection and to emulate or mimic the rock piles <br />from historic underground mine workings to provide wildlife habitat. These plated areas <br />would not be revegetated because the coarse rock prevents erosion. Drainage channels or <br />benches developed on the OSAs will be candidates for similar plating with rock and some <br />slopes may, in entirety, be suitably plated with the overburden as a backdrop for other <br />compatible uses. <br />The stability of the reclaimed SGOSA was addressed in Section 5.7.1 of this Project <br />Description. This analysis indicates that the reclaimed area will be stable over the long <br />term. <br />The final reclaimed surface of the SGOSA will be graded to conform to the storm water <br />runoff patterns discussed previously in Section 5.7.1 and included in Appendix 12, <br />Volume VI. A discussion of diversion/ conveyance channels and detention basins for the <br />final SGOSA configuration also is provided in Section 5.7.1 of this document and <br />Appendix 12, Volume VI. <br />Cripple Creek & Victor Gold Mining Company <br />Cresson Project Mine Life Extension 2 <br />12 -11 <br />
