The structure will consist of steel beams supported on legs bolted to a concrete footer. The beams will be either 10 <br />(up to three) or 14 (one each) feet in length, and the legs will be approximately 6.5 or 8 feet high. The footers will <br />be approximately 4 x 4 x 4 feet. The 14-foot beam structures will be placed over the 24-inch borehole. Also, a 7 x <br />10 x 0.3 foot pad will be poured around the 24-inch borehole. The 10-foot beam structures will be placed over the <br />6-inch diameter borings. A 7 x 6 x 0.3 foot pad will be poured around these borings. <br />As part of the utility installation described above, TCC will advance up to three additional 6-inch cased borings at <br />the existing NMD Power Borehole. This is required due to problems encountered in grouting the casings as <br />approved in TR00-37. These borings will be located on the same pad as the NMD Power Borehole, as they will <br />terminate in the same entry underground as the NMD Power Borehole. During boring of the holes, the existing <br />mud pit will be utilized, although it will require that it be dug out and reestablished at the site. It is in the same <br />location as it was originally located. When the borings are completed, the pit will be backfilled and the pad graded <br />as previously described. <br />6-Main North Substation No. 13 (MROS-201) <br />The proposed substation installation will consist of six concrete pads, including five designed to support <br />transformers. The sixth pad will be a foundation fora 14 x 30 foot prefabricated metal building, containing <br />electrical controllers and switch-gear. A buried ground-bed, adjacent to the substation will complete the substation <br />installation. The proposed substation will be enclosed by a 120 x 110 foot, 8-foot high chain-link fence. The <br />substation location is shown on Map 24. Substation details and a materials list, are included in Exhibit 49E. <br />It is important to note that TROS-48 (6-Main North Shaft and Associated Ancillary Equipment and Facilities) <br />addresses the construction, operation, and reclamation of the 6-Main North ventilation shaft and associated <br />ancillary equipment and facilities for TCC's Northern Mining District. TROS-48 addresses road construction, <br />extension of a 69KV power-distribution line from the existing substation at the Northwest Mains ventilation shaft, <br />construction of the ventilation shaft and utilities pad, shaft boring and lining operations, and the potential associated <br />impacts and control/mitigation/reclamation measures.. Details for the underground utility components for the 6- <br />Main North Shaft and Substation No. 13 are addressed in both the TROS-48 and MROS-198 (6-Main North Utility <br />Boreholes) submittals, and are shown on the related Maps 23, and EX16E-M1 and M2. <br />Mine Water Recyclin~ Svstem -Fish Creek Borehole (MR 02-1791 <br />(Note: Text for Mine Water Recycling System moved to pages 2.05-50 through 50.6) <br /> <br />MR08-230 2.05-65.3 11/20/08 <br />
