The structure will consist of steel beams supported on legs bolted to a concrete footer. The beams will be either <br />10 (up to three) or 14 (one each) feet in length, and the legs will be approximately 6.5 or 8 feet high. The <br />footers will be approximately 4 x 4 x 4 feet. The 14 -foot beam structures will be placed over the 24 -inch <br />•borehole. Also, a 7 x 10 x 03 foot pad will be poured around the 24 -inch borehole. The 10 -foot beam <br />structures will be placed over the 6 -inch diameter borings. A 7 x 6 x 0.3 foot pad will be poured around these <br />borings. <br />As part of the utility installation described above, TCC will advance up to three additional 6 -inch cased borings <br />at 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 <br />graded as previously described. <br />6 -Main North Substation No. 13 (MR05 -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 for a 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 <br />substation installation. The proposed substation will be enclosed by a 120 x 110 foot, 8 -foot high chain -link <br />fence. The substation location is shown on Map 24. Substation details and a materials list, are included in <br />Exhibit 49E. <br />It is important to note that TR05 -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. TROS48 addresses road construction, <br />• extension of a 69KV power- distribution line from the existing substation at the Northwest Mains ventilation <br />shaft, construction of the ventilation shaft and utilities pad, shaft boring and lining operations, and the potential <br />associated impacts and control/mitigation/reclamation measures. Details for the underground utility components <br />for the 6 -Main North Shaft and Substation No. 13 are addressed in both the TR05 -48 and MR05 -198 (6 -Main <br />North Utility Boreholes) submittals, and are shown on the related Maps 23, and EX16E -M1 and M2. <br />r � <br />Mine Water Recycling System — Fish Creek Borehole (MR 02 -179), <br />(Note: Text for Mine Water Recycling System moved to pages 2.05 -50 through 50.6) <br />MR08 -230 2.05 -65.3 11/20/08 <br />
