• drill pad will also be constructed at this Location. <br />Total footage to be drilled for all three holes is 1095 feet. Hole diameter will equal SK <br />to 6 inches. <br />Seismic Investigation <br />Three seismic lines will traverse the permit area. Total length of the lines, within the <br />permit area, are 12,600 ft. Holes for the seismic charges will be hand (powered) angered <br />(1-2 inch diameter) to a depth of 5 ft. each. The holes will be on 50 ft. centers for e <br />total number of holes equaling 229. Maximum explosive per hole is 1/3 pound. Brushing of <br />the 5-foot wide lines will be accomplished by hand. <br />Seismic blasting operations will not be conducted within 7,000 feet of any building, or <br />500 feet of an active or abandoned underground mine. A Special Use Permit for seismic <br />testing end blasting will be obtained from the Routt County Clerk's office prior to <br />exploration. All local, Stet e, and Federal regulations will be strictly adhered to during <br />this project. <br />• Reclamation Costs <br />Upon completion of the drilling project, all areas will be reclaimed with the exception of <br />the monitoring well and access to the well which will be reclaimed et a later date. Upon <br />final abandonment of the monitor well with grout end the pl atement of the cement plug, the <br />PVC casing will be cut off at three feet below ground surface, with the remaining three <br />feet of hole bac kfilled with topsoil, compacted, and seeded. Drill holes will be plugged <br />in accordance with methods described in Tab 78. All areas will be retopsoiled by pushing <br />the topsoil back over the disturbed area. This includes the roads and drill pads. The <br />areas will then be revegetated with the seed mix shown on page 72-1-5. <br />The seismic line holes will be reclaimed by placing cuttings into the holes. Any area <br />that had been brushed by hand will not be planted due to natural reinvasion of brush. <br />Estimated Reclamation Costs <br />1. Seismic Costs <br />1.
