Once the borrow material is within the moisture specification (0 to +3% of <br /> optimum moisture content), the keyway will be completed by placing 8" lifts into <br /> the keyway excavation and compacting with mechanical methods sufficient to <br /> bring the density to 95% of maximum dry density. <br /> Following completion of the keyway, construction of the CCL will begin <br /> conforming to the geometry shown in Exhibit F Reclamation Plan Sheets 2-3. <br /> Construction will proceed by placing 8" lifts of moisture conditioned (0 to +3% of <br /> optimum moisture content), weathered claystone around the perimeter of the <br /> excavation followed by compaction with a sheepsfoot compactor or similar with <br /> sufficient compactive energy to bring the lifts to 95% of maximum dry density. <br /> Verification of final CCL density shall be performed at a frequency of once per <br /> 10,000 yd3 with a nuclear densometer. <br /> Following backfilling of the slopes, a protective shell shall be as shown in Exhibit <br /> F Reclamation Plan Sheet 3 (Typical Section). to the elevation of the normal <br /> pool. The specifications for the protective shell are given in notes for Exhibit F <br /> Reclamation Plan Sheet 3 (Typical Section). <br /> Following construction of the CCL in Cell 2, Additional soil cement slope <br /> protection shall be installed on the WSR's slopes as shown in plan view on <br /> Exhibit F Reclamation Plan Sheet 1 in cross section on Exhibit F Reclamation <br /> Plan Sheet 2. A soil cement detail is also given in Exhibit F Reclamation Plan <br /> Sheet 2. The purpose of this additional slope protection is to protect the two <br /> Sinclair gas pipelines from potential head-cutting erosion that could otherwise <br /> occur during significant flooding events. <br /> (b) Post Mining Land Use Comparison <br /> Post mining land use will differ from pre-mining land use in that water storage <br /> reservoirs will occupy a significant portion of surface area and residential <br /> structures may be constructed. Otherwise, the agricultural use will remain similar <br /> to the existing land use. <br /> (c) Description of How the Reclamation Plan will Meet the Requirements of <br /> Section 3.1. <br /> The reclamation plan specifications described herein are designed to meet the <br /> requirements of Section 3.1 of the Mineral Rules and Regulations of the <br /> Colorado Mined Land Reclamation Board. Completion of the reclamation plan as <br /> specified shall therefore meet the requirements of Section 3.1 <br /> (d) Topsoil Segregation <br /> At a minimum, topsoil shall be segregated in areas shown in Exhibit C-2 Mining <br /> Plan Map. <br /> (e) Reclamation Sequence and Timetable <br /> An estimate of the sequence and periods of time for each reclamation activity is <br /> given in Table 6.4.5-3. <br /> Amen Aggregate Resource <br /> Specific Exhibits <br /> Page 15 of 84 <br />
