3. Describe the estimated topsoil depth and how topsoil will be salvaged, stockpiled and <br /> redistributed for the re-establishment of vegetation. Specify approximate topsoil <br /> redistribution depth: <br /> topsoil (to depth of 6-8 inches)along edge of the roadway to be expanded will be dozed into piles at the <br /> end of each switchback and the toe of each pile will be silt-fenced. Drainage from the roadway side-ditch <br /> will be directed away from the piles. <br /> Pine saplings if any will be saved and planted into topsoil piles on a tem op_ra[y basis for use in event of <br /> roadway not being needed for future well maintenance. <br /> Dewatering boreholes are planned to remain in perpetuity to extract groundwater to prevent intrusion <br /> into mine workings so road is not planned to he r _ .laimed. If wells are not converted to perpetual <br /> pumping then topsoil will be re-distributed to depth of 6-8 inches, zone 5 seed mix will be placed, and <br /> distrirhPd areas rP-planted with saved pine saplings to the Pxtent present at start of t mgram <br /> 4. Describe how drill holes will be plugged (refer to Rule S.4 of the Rules for required <br /> abandonment procedures): <br /> Dewatering holes are planned for perpetual dewatering of London Mine workings so <br /> plan is not successful, then each borehole will be filled with sodium bentonite-type gel <br /> o the top ot the aqul er (3bO teet below top ot casing and then from at the Be-en <br /> shale contact filled by neat cement grout to ground surface. <br /> S. Describe how portals, adits, shafts, ponds, excavations, or other disturbances will be <br /> reclaimed (refer to Rule 3 and Rule S for specific reclamation performance standards). <br /> You may wish to contact the Division for closure specifications. <br /> Ophir Tunnel Portal will be reinforced with a 5 or 6 foot diameter steel culvert and <br /> elesed with a steel deeF welded te the eulvert with an inteffial padleek net aeeessible te <br /> casual observer. Surrounding ground will be graded around the culvert to prevent <br /> access to the tunnel. <br /> Drill pads will be reclaimed by ripping; replacement of topsoil and reseeding. <br /> Replacement of pine saplings to density prior to disturbance. <br /> Form 2—Public File Page 9 of 14 <br />
