EXHIBIT G WATER INFORMATION <br /> 6.4.7(1) and 6.4.7(2) <br /> Surface Water <br /> The northern extent of the site, the WRL area, is within 300 feet of North Clear Creek. Russell <br /> Gulch runs sub-parallel to the northern extent of the site. The Clear Creek County parcels of the <br /> site are well outside of FEMA identified floodplains while the Gilpin County parcels do not have <br /> available digital data. No wetlands are identified or anticipated within the site. No aquifers will <br /> be impacted by the operation. <br /> Protection of the prevailing hydrologic balance is achieved by preventing an increase in offsite <br /> runoff during and following mining as well as preventing an increase in sediment discharge <br /> before and after mining. In conjunction with these goals, water quality is ensured during mining <br /> by complying with required CDPHE discharge permits. Finally, protecting the prevailing <br /> hydrologic balance means ensuring that no area water rights are injured through runoff diversion. <br /> The water handling plans for the Young Ranch Resource have all been designed to accomplish <br /> these goals. <br /> Pre-mining Surface Hydrology <br /> Surface flows that do not occur within the active mining area will be diverted around the <br /> disturbed area via> 2-foot-tall isolation berms and/or small ditches and will infiltrate into the <br /> deep organic litter and sandy loamy substrate of the undisturbed areas of the site within 72 hours. <br /> Due to the coarse soil textures found at the site, permeability is moderate to high and most <br /> precipitation and runoff percolates quickly into the ground. Map G-1 shows the approximate <br /> direction of drainage throughout the site prior to mining, during mining, and post-mining during <br /> reclamation. All maps are included in Appendix 1. <br /> The hydrologic conditions at the Young Ranch Resource consist mostly of surface water <br /> drainage along long-established pathways and areas. Site soils are identified in NRCS surveys as <br /> rock complexes that are predominantly hydrologic soil group D. There are portions of the <br /> Tahana-Legault-Complex (roughly 40%) that are hydrologic soil group B.
