• Remove all surface equipment, compressors, trailers, C -Cans, sanitary facilities, <br />ventilation fans, and debris from the site. Estimate two weeks. <br />• Over - excavate temporary ore stockpile and loading area, placing material back in the <br />mine. Estimate two weeks. <br />• Grade all disturbed areas to conform to natural contours, or to slopes shown on Map F -1, <br />and a maximum of 311:1V. Estimate three weeks. <br />• Conduct surface radiometric survey to document return to baseline levels. Estimate two <br />weeks. <br />• Close vent shafts as described in 33.5 (6). Disc and re -seed the trails that access the <br />existing and potential additional vent holes. Estimate two weeks. <br />• Spread topsoil over re- contoured slopes; construct pockets on steepest slopes; re -seed <br />with approved seed mix; spread remnant woody material to minimi wind erosion and <br />stabilize reclaimed areas; fence around re- seeded area. Estimate one month. <br />The above mining reclamation may include some simultaneous work, and should be complete <br />within four months of mining cessation. <br />3.1.5: <br />(2) Please clam the length of portal to be collapsed and methods of compaction to ensure <br />post reclamation stability. <br />The portal/adit is constructed with a split culvert and timbering approximately 100 feet in length <br />with a welded steel frame and locking steel door entrance. The haul road is cut down to the floor <br />level of the alit and the ground above the portal has been reclaimed with topsoil and vegetation <br />is growing (see Photograph — Last Chance Mine Portal on June 6, 2008, enclosed). Reclamation <br />plans are not to collapse, the portal, but lock the door and backfill the road entry way and contour <br />the site as shown on Map F -1. <br />(3) Please provide a final grading plan that demonstrates final, permanent stormwater <br />controls that prevent precipitation interaction with reclaimed waste and portal areas. <br />Revised Map F -1 shows the reclaimed area, including buried portal, to be under a gently sloping <br />hill such that any precipitation will ran off the reclaimed area and not collect or flow into the <br />reclaimed waste and portal areas. Final grading will not be done until the sediment traps are dry, <br />the riprap removed, and the pits backfilled with the materials that were excavated from the pit. <br />Any topsoil removed will be stockpiled and seeded to prevent erosion. <br />(5) The handling of uranium ores shall he addressed in Exhibit T. However please provide a <br />narrative as to how Nuvemco will ensure that on -site radiation will not exceed surrounding <br />area background radiation baseline levels. Reclamation measures must ensure that. <br />On or before April 28, 2010, Nuvemco will complete a new Surface Background Radiometic <br />Survey to replace the one included as Appendix A. The new survey will cover the 2.5 acres of <br />the mine disturbance area on a grid of approximately 50 ft centers. Grid locations will have GPS <br />coordinates and include gamma radiation counts per second (cps) as measured by a Radiation <br />Solutions RS -125 spectrometer as used in the original survey.
