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 /> The portal pad areas to be used have been pre-disturbed and contain no topsoil. The sites will be monitored for signs <br /> of erosion and weeds during operation,and treated as needed. <br /> Upland areas used for roadways,trenching or drilling will be stripped of whatever topsoil can be feasibly salvaged. <br /> Topsoil depths are variable, and range from nearly no topsoil depth to several feet in thickness. Soil will be pushed <br /> away from planned disturbance, protected during prospecting, and respread during reclamation. <br /> 4. Describe how drill holes will be plugged (refer to Rule 5.4 of the Rules for required <br /> abandonment procedures): <br /> All drillholes are expected to be dry{since it is known by the underground workings directly below that there is limited <br /> water <br /> Dry holes will be backfilled with cuttings, then plugged mechanically or with cement at or a few feet below the collar. <br /> Any holes that Intercept groundwater will be sealed with bentonite abandonment gel throughout the wet sections, <br /> then backfilled with cuttings in the dry sections, and plugged at the collar. Any cuttings remaining on the surface will <br /> be scattered. <br /> 5. Describe how portals, adits, shafts, ponds, excavations, or other disturbances will be <br /> reclaimed (refer to Rule 3 and Rule 5 for specific reclamation performance standards). <br /> You may wish to contact the Division for closure specifications. <br /> Portals will be closed and safeguarded at the conclusion of prospecting activity. This may involve backfilling the adit <br /> with the muck material that was removed earlier,and recontourin ,or by installing a locked steel gate in anchored <br /> steel sets. In the case of a reopened shaft,it will be backfilled,closed by permanent panel,or locked steel closure. <br /> !f the landowner wishes for the lockable steel doors are to remain as permanent features,a letter will be provided in <br /> the application.) Any pre-existing adit drainage will be allowed to continue to flow(such as by buried pipe)to the <br /> existing percolation ponds. Drill pads will be recontoured,trenches will be backfilled and contoured,and all areas will <br /> have the salvaged topsoil respread. All areas disturbed or affected by activity will be graded to a stable gradient(31 <br /> max). All debris and contaminants will be removed. Drill pads,cut and fill slopes associated with new roads, and <br /> backfilled openings will be seeded. <br /> Form 2- Public File Page 9 of 14 <br />
