CA <br />DSSFIRE AGGREGRATE <br />SERVICES, LLC <br />General Water Hydrology and Water Quality <br />EXHIBIT E <br />Hydrology and water quality issues are addressed at length in Exhibit G: Water Information. The <br />Applicant will comply with applicable water rights, laws, and regulations, and water quality laws and <br />regulations. No dredge or fill in waters of Colorado or the United States is proposed and no temporary <br />or large siltation structures will be placed except as required by permits and will be removed in <br />accordance with those permits. No storm water structures are proposed which are intended to retain <br />storm water for longer than 72 hours. <br />Earth Dams <br />Mining will be done only in areas which will not present potential for negative impact on the stability of <br />any off -site earth dams. Except for storm water control systems in and around plant areas, there will be <br />no earth or other dams constructed. Berms and basins will contain less than (1) acre -foot of water at <br />any time, including immediately following 24hr - 25yr storm events except as approved by the Colorado <br />Division of Water Resources. Mining is expected to remain above the normal ground water table. No <br />permanent ponds are planned. <br />Erosion control <br />All surfaces will be stabilized and protected to control erosion. Stockpiles of soil and excess fines will be <br />protected against erosion, traffic, and weed invasion either by seeding or application of dust control and <br />crusting agents such as polymers or other soil treatments. <br />Groundwater <br />The Applicant shall comply with all applicable statewide and classified standards based on existing and <br />reasonably potential future uses and with new standards which may be applicable in the future. The <br />operation is designed to have no reasonable potential to adversely impact groundwater quality or <br />quantity or cause any further lowering of quality. It is not anticipated that tributary water will be <br />encountered in the mining. The Applicant will comply with any conditions as established by permits. <br />Wildlife Safety and Protection <br />Wildlife issues are addressed in Exhibit H: Wildlife. A buffer zone will exist between the pit and major <br />features either on- or off -site. Since mining will be done in annual steps there will be no long -term, wide <br />barrier to migration. The buffer zones areas not yet mined and reclaimed areas will provide space for <br />wildlife to migrate around the pit operations. Temporary fencing will be used to reduce potential for <br />livestock and wildlife to graze on areas being reclaimed. Priority however will be given to use for <br />livestock rather than wildlife <br />Wildlife Habitat Management and Creation <br />In accordance with the wishes of the landowner, and based on current and planned use as grazing land, <br />no action will be taken to specifically create or improve wildlife habitat in the permit area. Priority shall <br />be given to agricultural use for livestock not wildlife. <br />Prepared by Tegre Corp. <br />1199 Main Ave., Suite 101 <br />Durango, CO 81301 <br />(970) 828 -1811 <br />
