potential plugging materials, that are generally superior to conventional cement grout, is provided in <br />Appendix E. Surface casing will be cut-off at or below grade. Reclaimed drillhole locations will be <br />marked with either a steel fence post or a metal survey cap at or below ground level (used where <br />agricultural cropping occurs). All drillhole locations will be accurately surveyed, and distinctly <br />numbered, allowing for future identification. Abandonment reports will be prepared and filed, as <br />required by applicable regulations. When no longer needed, monitoring wells will be plugged, <br />sealed, and abandoned in essentially the same manner, with the stipulation that cement slurry will be <br />used for plugging the well. <br />~loration Site Reclamation: Following completion of exploration activities (drilling, sampling, <br />and geophysical logging) for each exploration site, any drillholes not converted to monitoring wells <br />will be plugged, sealed and abandoned, as previously described, and exploration disturbance will be <br />reclaimed. Site reclamation will follow completion of exploration activities for each site as soon as <br />reasonably practical, recognizing however, that certain reclamation activities may be coordinated to <br />take advantage of equipment and personnel availability. Seeding of reclaimed exploration sites will <br />occur during the first favorable seeding period (typically late fall [preferred], or early spring) <br />following completion of site reclamation. The following summarizes the steps and general sequence <br />for reclamation of exploration disturbance areas: <br />1) On completion of exploration activities at a given site, all trash, debris, and exploration <br />equipment and supplies will be removed from the site. <br />2) For drill-sites, excess drilling fluids may be pumped from mud pits for off-site disposal, and <br />the mud pits allowed to dry-out. Mud pits or excavated trenches will be backfilled with the <br />excavated material and compacted to minimize any settling. Any excess drill cuttings will be <br />spread over the drill pad, and drill pads, trenched areas, and any new access road segments <br />graded to approximate their original configuration and blend with the adjacent terrain. <br />3) Stockpiled or windrowed topsoil will be redistributed at a uniform thickness over disturbed <br />areas. <br />4) Disturbed areas will be reseeded to stabilize the surface and control erosion using the <br />following seed mix, or a mixture developed in consultation with the appropriate landowner or <br />as specified by the CDOW (for areas with state surface ownership). Replaced topsoil will be <br />scarified prior to seeding, and areas will be drill or broadcast seeded at the prescribed rates. <br />A harrow or similar implement will be used to drag the surface and cover the seed following <br />seeding. <br />Species PLS lb/acre <br />Mountain brome (Garnet) 3.0 <br />Western wheatgrass (Arriba) 2.0 <br />Slender wheatgrass (San Luis) 2.0 <br />Bluebunch wheatgrass (Goldar) 1.0 <br />Orchardgrass (Paiute) 2.0 <br />Green needlegrass ].0 <br />Alfalfa (Ladak) ?•0 <br />Total PL5 13.0 (double for broadcast) <br />Estimated reclamation liabilities are detailed in Table 2, for the purpose of determining reclamation <br />bonding requirements. <br />Cniv Camp Pm~en NO! <br />fi]oJ 10 <br />
