Reclamation of power lines owned by Powderhorn Coal Company will be started <br />within a year following the determination that they are no longer needed or serve <br />no use in the post mining land use. Poles and guy wires will be excavated or cut <br />off a minimum of I-foot below grade. <br />Cameo Borrow Area No. 2 <br />Final contours for the Cameo Borrow Area No. 2 are shown on Exhibit 52, Tab <br />13. Cross-sections representing the existing and final grade are shown on <br />Exhibit 53, Tab 13. The area will be graded to the final grade and approximately <br />6" of topsoil from adjacent disturbance areas or nearby stockpiles will be <br />distributed on the surface. <br />Coal Canyon Realignment <br />As part of the design for CRDA -2, the Coal Canyon drainage channel was <br />realigned to provide a more uniform, controlled flow between CRDA 1 and 2. <br />The four rock check dams constructed in the channel have caused significant <br />deposition and necessitated frequent maintenance. In order to assure the <br />channel is in equilibrium with the flow regime, the rock check dams will be <br />removed and the excess sediment will be harvested for use as refuse cover soil. <br />The drainage channel will be graded to an approximate uniform grade to the <br />cross sections presented on Exhibits 53 and 55. Berms located along the middle <br />• and lower sections will be leveled so the channel blends naturally into the <br />adjacent terrain. Berms will not be utilized to provide the necessary flow capacity <br />along the segment between the dip section concrete structure at the upper end <br />and the two 81" by 59" culverts at the lower. Additionally, the Pond 6 <br />embankment will be built up as appropriate so that an embankment of <br />substantial width is provided for the channel rather than the current configuration <br />of the pond embankment with a narrower berm on top. The rock from the check <br />dams will be used for the construction of rock groups to be placed on the <br />reclaimed surface of CRDA-1 & 2 or other reclamation uses. Since material <br />generated from the Coal Canyon Realignment will be utilized for the reclamation <br />of CRDA-1 & 2, the realignment will be performed concurrently with refuse pile <br />reclamation. <br />Roads <br />Most of the roads listed in Table 13-2 will be reclaimed as part of the operations <br />area that they are associated with. In General, each roadway will be excavated <br />down to the original wash bottom at each drainage crossing, and culverts will be <br />removed. The excavated material will be placed in road cuts or designated fill <br />areas adjacent to the roadway. Fill material will be placed in uniform lifts and <br />compacted as necessary to insure stability. The cut slopes formed at the <br />drainage crossings and the cut and fill slopes adjacent to the road will be <br />regraded and rounded to conform each site to the surrounding terrain. <br /> <br />14-13 <br />(Rev. 8/01) <br />
