Drawing No. CCVA9-SA-1 shows the same information in more detail. The drawing <br />includes a plan view of the terrain as it was in August 2007. The storm water management <br />basins and facilities are superimposed on the topography to illustrate how the systems will <br />function and be developed as the mine perimeter expands to its final limits. General flow <br />directions are illustrated for both overland flow and diversion channels. The basin <br />designations shown on the drawing are the same as used in the SEDCAD4 results (except <br />that SEDCAD4 also assigns a corresponding number to each structure in addition to its <br />descriptive label). <br />The proposed sediment detention ponds (EMP's) are illustrated on the drawing with <br />their approximate footprint to scale. The size and design of diversion channels are tabulated <br />for each basin in the upper right corner. Some of the sub-watersheds will not change from <br />the approved plans of Amendment No. 8. Those basin designations and basin areas <br />(created by Golder Associates for Amendment No. 8) are shown as circle icons. <br />Where possible, the EMP locations have been selected to serve a dual function of <br />storm water management durin operations and wildlife watering holes after closure. In that <br />manner, the ponds can be. constructed for perpetual use. Only modest revisions to the <br />facilities may be required to convert from operational use to closure configuration,. <br />Post Closure Arrangement <br />The proposed arrangement of the storm management system after closure is illustrated <br />on Figures 3 and 4 and on Drawing No. CCVA9-SA-2. Topographic depression areas <br />that will be tributary to the mine areas after closure are hatched in gray and the basins <br />are crossed out on the schematic. Those are the basins that will be removed during the <br />mining activities, and will drain into the central depression area, and will no longer be <br />tributary requiring the management of storm water. These EMP ponds, whose function <br />will no longer be required, may be modified and used as wildlife watering holes, or <br />removed during reclamation activities. <br />Client:CC&V Gold Mining Co. 4!11/08 <br />Title: Storm Water Management, MLE Page 8 <br />
