To provide access in the area for ranching purposes,the Haul Road B from Highway 13 will be left <br /> in place after mining is complete. The haul road will be narrowed from 26 to 12 feet, the asphalt <br /> removed, side slopes reduced to 4:1 and the sides revegetated. <br /> All mine support facilities are to be removed during final reclamation. Drilled holes and <br /> underground openings will be closed when no longer needed for the approved mine operation. <br /> Ponds, Stock Tanks, and Ditches <br /> All sediment control ponds and diversion ditches are to be removed during final reclamation of the <br /> site. To support the proposed post mining land use, small water impoundments (stock tanks) will <br /> be left to encourage an even distribution of grazing over the reclaimed site and to enhance the <br /> areas for wildlife. These ponds will also replace the existing water rights associated with the stock <br /> ponds that currently exist on the site. <br /> Backfilling and Grading <br /> All highwalls will be eliminated. Spoil will be graded to slopes no steeper than 3:1 (three <br /> horizontal to one vertical). Reconstructed stream gradients will approximate those of the premining <br /> streams, and stream channels will be restructured to complement regional stream patterns. Contour <br /> furrows will be constructed to reduce erosion. Overall, Colowyo's reclamation plan will serve to <br /> achieve contemporaneous reclamation and approximate original contour. However, a variance to <br /> Rule 4.14.l(1)(c)was granted during the initial permitting process to backfill as contemporaneously <br /> as practical in lieu of the 180-day or four-spoil-ridges requirement. Additionally, with the approval <br /> of PR-02,the Division has granted a variance to Rule 4.14.l(1)(c) for the South Taylor Pit. <br /> Six valley fills have been permitted for the disposal of excess spoil. Streeter Fill is at the north <br /> edge of the East Pit. West Pit Fill is adjacent to the Taylor Draw northwest of the West Pit. Section <br /> 16 Fill is in a sub-drainage along the West Fork of Good Spring Creek. Both the Streeter Fill and <br /> the Section 16 Fill have undergone a Phase III Bond Release and the requirement for quarterly <br /> inspections of the fills has been terminated. <br /> Two additional valley fills were approved with PR-02, one of the fills has been completed and the <br /> other is in the process of construction. These fills were designed for disposal of the initial box-cut <br /> spoil from the South Taylor Pit. The West Taylor Fill is being constructed in the West Fork of <br /> upper Taylor Creek and the East Taylor Fill was constructed in the East Fork of upper Taylor <br /> Creek. The final valley fill is associated with the Collom Pit and is currently in the process of <br /> construction within the Little Collom Gulch drainage. <br /> Topsoil <br /> Topsoil performance standards are found in Section 4.06 of the PAP (Volume 1 for the East Pit, <br /> West Pit, Section 16 Pit, Facilities Area and Gossard Loadout; Volume 12 for South Taylor Pit; <br /> Volume 15 for Collom Pit). Additional information on the soil types can be found on Maps 5A, <br /> 5B, 5C, 5D and 6 of the PAP. Eighteen inches of topsoil was replaced on all graded sites through <br /> 2005. One exception is the Section 11 Pit, where 12 inches of topsoil was placed. With the <br /> approval of TR-62, the topsoil replacement depth for all post 2005 remaining reclamation in the <br /> 24 <br /> Permit Revision No.5(PR-05),G 1981-019 <br />
