6 <br />3. Describe the estimated topsoil depth and how topsoil will be salvaged, stockpiled and redistributed for the re-establishment of <br />vegetation. Specify approximate topsoil redistribution depth: <br />6" of topsoil exist. If topsoil is striped it will be stockpiled in windrows on the <br />uphill side of the disturbed area. Blading or grading is not proposed at the drill <br />sites unless the drill site is not level enough to accommodate the drilling rig. If <br />leveling is required the drill site would be 20 -feet in width and 40-feet in length <br />and accommodate the rig, water storage, drilling equipment, drilling supplies and <br />multiple crew vehicles. The rig would be oriented to minimize surface disturbance and <br />insure the most level area possible. Minor cuts and fills may be generated and have been <br />included in the disturbance estimate within the 20' by 40' area. <br />4. Describe how drill holes will be plugged (refer to Rule 5.4 of the Rules for required abandonment procedures): <br />Providing that no water is encountered while drilling, the hole would be back-filled <br />and a cement surface plug would be installed in the hole. In the event that water <br />is encountered during drilling, bentonite chips would fill the abandon hole and a 20' <br />cement cap placed over the bentonite chips to surface. Should an alternate plugging <br />method be requested by the BLM that procedure would be followed. Drill cuttings would <br />be spread over the surrounding area. <br />5. Describe how portals, adits, shafts, ponds, excavations, or other disturbances will be reclaimed (refer to Rule 3 and Rule 5 for <br />specific reclamation performance standards). You may wish to contact the Division for closure specifications. <br />No other disturbances are proposed except for drill holes and access roads. <br />ti. Describe how roads will be reclaimed or returned to their pre-prospecting (,or better) condition: <br />New roads will be reshaped to original contour and roughened with a-backhoe then v µµM µ <br />reseeded and covered by hand raking or four-wheeler and harrow leaving a roughened surface. <br />Obstacles would be place to preclude travel along the reclaimed route. Existing roads <br />would be reclaimed utilizing the same procedure unless directed to leave the existing <br />roads open by the BLM. <br />- -- ----------------
