Marr Mine -Borehole Reclamation Plan <br />January 29, 2002 <br />Page 3 <br />development; and installation, operation, and maintenance of any pumps or other equipment <br />necessary to provide for conststent water supply flows. <br />Well Pluggine, Reclamation and Reporting <br />For any wells that would not be retained for future beneficial use, Kerr would complete well plugging <br />and reclamation. Well plugging and reclamation would involve completion of the following activities, <br />which are consistent with CDMG Rules and Regulations for Surface Mining (4.07): <br />Pluetnne - <br />For boreholes or wells not completed in an identified aquifer, the holes would be ftlled with <br />drill cuttings, sand, or other suitable (non-tonic) materials to within 10 feet of the natural or <br />reclaimed ground surface and the remainder of the hole would be filled to within 3 feet of <br />the ground surface with cement. <br />For boreholes or wells completed in an identified aquifer(s), the plugging procedure would be <br />the same except that a cement or bentonite plug would extend at least 20 feet above and <br />below any water-bearing zone(s). <br />For boreholes or wells exhibiting artesian flows at the surface, plugging would involve <br />removal, perforating or ripping oC the casing in the saturated zone to allow plug placement <br />across the entire hole diameter. The cement or bentonite plug will extend from the bottom <br />of the hole to within 10 feet of the surface with a cement plug from the 10 foot level to <br />within 3 feet of the surface. <br />Surface Reclamation - <br />Surface reclamation would involve cutting off any casing extending above the ground surface <br />at or below ground level; collection and removal from the site for disposal of the casing and <br />any debris; backfilling of remaining casing and any holes level with the ground surface; <br />grading of the surface disturbance azea to blend with the surrounding teaain, and seeding to <br />reestablish a vegetative cover. <br />Filing of ~~/ell Abandonment Reports - <br />Within 60 days of completion of the borehole reclamation program, Kerr will complete and <br />file the appropriate well abandonment reports with the Office of the State Engineer and the <br />DMG. <br />Kerr plans to complete field borehole reclamation activities during the 2002 Geld season with <br />completion anticipated by August ]2, 2002. Assuming that the determination of potential for <br />beneficial use and BLM review and concurrence on well retention Eor beneficial use can occur in a <br />reasonable timeframe (i.e.: prior to the end of June 2002), this data is achievable. <br />
