Exp loration Disturbance <br />• Following completion of exploration activities (drilling, sampling, and geophysical logging) for each exploration <br />site, any drillholes not converted to monitoring wells will be plugged, sealed and abandoned, as previously <br />described, and exploration disturbance will be reclaimed. Site reclamation will follow completion of exploration <br />activities for each site as soon as reasonably practical, recognizing however, that certain reclamation activities may <br />be coordinated to take advantage of equipment and personnel availability. The following summarizes the steps and <br />general sequence for reclamation of exploration disturbance areas: <br />1) On completion of exploration activities at a given site, all trash, debris, and exploration equipment and <br />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 the mud pits <br />allowed to dry -out. Mud pits or excavated trenches will be backfilled with the excavated material and <br />compacted to minimize any settling. Any excess drill cuttings will be spread over the drill -pad, and drill - <br />pads, trenched areas, and any new access road segments graded to approximate their original configuration <br />and blend with the adjacent terrain. <br />:3) Stockpiled or windrowed topsoil will be redistributed at a uniform thickness over disturbed areas. <br />4) Disturbed areas will be reseeded to stabilize the surface and control erosion using the following seed mix, <br />or a mixture developed in consultation with the appropriate landowner or as specified by the CDOW (for <br />areas with state surface ownership). Replaced topsoil will be scarified prior to seeding, and areas will be <br />drill or broadcast seeded at the prescribed rates. A harrow or similar implement will be used to drag the <br />surface and cover the seed following seeding. <br />Seeding of reclaimed exploration sites will occur during the first favorable seeding period (typically late fall <br />[preferred], or early spring) following completion of site reclamation. <br />• <br />TR10 -73 2.05-106.3 05/21/10 <br />
