considered hazardous in nature. In the event that contaminated material is <br />identified, all work in the immediate area will cease. The fadility operator will <br />contact the Division of Mineral and Geology and a Colorado Registered <br />Professional Engineer or a Registered Environmental Manager. The listed <br />qualified individual(s) will prepare, supervise and implement a Remediation and <br />Disposal Plan conducted in accordance with the requirements of the governing <br />regulatory agencies. <br />Once backfilling operations commence, the material will be placed and <br />compacted to achieve a uniform topography. The backfill material will be placed <br />in uniform lifts and compacted using wheel-rolling techniques. The existing <br />moisture content of the material will determine whether moisture conditioning is <br />required to achieve optimum compaction. If required, water will be added to the <br />fill dirt during placement. <br />In addition to filling the above described channels, the disturbed ground will be <br />contoured such to direct any future flooding to a constructed a swale Will be <br />constructed near the southeast portion of the pit. The intention of this swale is to <br />contain future flooding within a defined channel and discharge this water into the <br />pit excavation. This swale will become a permanent feature of the overall <br />reclamation plan. <br />Erosion protection will be incorporated into this swale near the point where the <br />swale discharges into the pit. The attached map shows the location of the Swale <br />along with details of the erosion protection. <br />TOPSOIL REPLACEMENT AND VEGETATION <br />Topsoil replacement and vegetation will occur as discussed in the approved <br />Reclamation Plan. Topsoil will be placed to a thickness between 6 and 8-inches. <br />Seedbed preparation may include ripping, discing, fertilizing, dragging, harrowing <br />and furrowing. The seed mix recommended by the Soil Conservation District is <br />listed below: <br />SPECIES PLS/ACRE <br />Jose Tall Wheatgrass 10.2 <br />Alkalai Sacton 0.6 <br />Yellow Sweet Clover 2.8 <br />Sand Dropseed 0.2 <br />Crested Wheatgrass 4.0 <br />Seeding for inside the perimeter of the pond to water level: <br />SPECIES PLS/ACRE <br />Reed Canarygrass 5.3 <br />Red Top 0.3 <br />M-1991-079 <br />Revised May, 2010
