E.6 Constraints on Estimated Time to Complete Reclamation <br />It is anticipated that revegetation of the Topaz Mine site wilt take approximately 3 years. <br />However, the success and progress of revegetation efforts are based on seasonal growth patterns, <br />precipitation, weather patterns, and natural disturbances. For this reason, the reclamation <br />schedule may be extended by factors outside of the control of Denison. <br />E.7 Proposed Reclamation Techniques and Locations of Road Features <br />Roads that have been created by the operation at Topaz Mine are identified on Figure C-3. These <br />roads include roads that have historically been used to gain access to vent holes as well as new <br />roads to proposed vent holes. The disturbed area associated with the vent hole roads is <br />approximately 2.5 acres. Roads labeled as permanent on Figure 2 will not be reclaimed as they <br />will be used for multiple other uses. <br />Most of these roads are on relatively flat areas that do not have significant cuts or fills. The roads <br />will be reclaimed by: <br />1. Regrading any cuts and fills to reestablish the original ground contours and drainages. <br />2. Ripping the roads to a depth of 12 to 18 inches. <br />3. Placing 6 inches of loose topsoil in locations where topsoil was removed. <br />4. Seeding the soil with the approved reclamation seed mix. <br />E.8 Measures to Minimize Loading of Sediment to Surface Waters <br />The catchment basin located at the north end of the WRA will be backfilled to the approximate <br />original contours with salvaged topsoil placed on top. The area will then be scarified and seeded <br />with the approved reclamation seed mix. The permanent diversion channels uphill of the surface <br />facilities area will be left in place to minimize the amount of runoff flowing down the slopes of <br />the reclaimed WRA. <br />E.9 Disposition of Buildings and Ancillary Facilities <br />Trailers will be hauled to another facility, sold, or hauled to a landfill for disposal. Non- <br />putrescible solid waste meeting the definition of"inert waste" under the Colorado Mineral Rules <br />and Regulations (e.g., concrete, masonry, asphalt, and other inert solids) will be broken up and <br />buried on site. All concrete foundations and pads will be broken, using a hydraulic excavator <br />with a concrete breaker (or equivalent) to dimensions of 5 feet or less. The broken concrete will <br />5-18-2007 Exhibi[ E Rec Plan E-$ <br />
