4 <br /> (4. EXHIBIT E <br /> CROSSFIRE AGGREGRATE <br /> SERVICES.LLC <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 /> reasonable 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 zone in 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 /> Topsoil <br /> Approximately 2-4 inches of soil based on USDA data will be removed prior to extraction and stockpiled <br /> for protection. Any woody vegetation will be removed. Except for the plant areas, relocation of <br /> stockpiled soil will be done on an annual basis as mined areas are reclaimed. If necessary, as material is <br /> available and as authorized by DRMS, materials may be added to amend and improve soil including <br /> fertilizers,commercial soil amendments, manure from livestock, non-toxic organic materials from on-or <br /> Prepared by Tegre Corp. <br /> 1199 Main Ave., Suite 101 ) r t 'C. <br /> Durango,CO 81301 ^� <br /> (970)828-1811 <br />
