The drill cuttings will be disposed of in the collection pit. Steel Schedule-40 or -80 pipe will be placed in <br />each of the nominal 13-inch diameter holes, and the annulus will be fully grouted. <br />In order to hang the power cables in the holes, a steel structure(s) will be constructed over the three cased <br />holes. This structure(s) will be a metal beam(s) and legs, bolted to a concrete footer(s). The beam(s) will <br />be either 14 feet or 10 feet (up to three) in length, and the legs will be approximately 6.5 or 8 feet high. <br />The footer(s) is approximately 4 x 4 x 4 feet. The 14-foot beam structure will extend over all three <br />boreholes. The 10-foot beam structures will be placed over individual or paired borings, if used. On <br />completion and casing of the borings, a 7 x 10 x 5-foot pad will be poured around the three power-drop <br />boreholes. <br />The bulk material and water drop boreholes will be completed as nominal 13-inch boreholes from the <br />surface to the underground workings from the pad above the 6-North Main entries. <br />MROS-198 2.05-45.6e 08/29/05 <br />
