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 pre-disturbed areas to be affected contain no topsoil. All sites will be monitored for signs of erosion and weeds <br /> 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 this project is located on a topographic divide. Groundwater will be limited <br /> to local fractures;there are no known aquifers. <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 /> Openings(adit or shaft)will be closed and safeguarded at the conclusion of prospecting activity. This may involve <br /> backfilling them with the muck material that was removed earlier, and recontouring, or by installing a locked steel <br /> closure in anchored steel sets (If the landowner wishes for the lockable steel doors are to remain as permanent <br /> features, a letter will be provided in the application.) Drill pads will be recontoured,trenches will be backfilled and <br /> contoured, and all areas will have the salvaged topsoil respread. All areas disturbed or affected by activity will be <br /> graded to a stable gradient(3:1 max) All debris and contaminants will be removed. Topsoded surfaces(drill pads, <br /> cut and fill slopes associated with new roads,and backfilled openings)will be seeded. <br /> Form 2—Public File Page 9 of 14 <br />
