J. J. Dudash -2- July 6, 2010 <br />6. Install 9-inch thick concrete lining in shaft. (1200 cubic yards of concrete) <br />7. Install escape hoist. <br />8. Install nitrogen generator system powered by electrical compressors. Power <br />from underground. <br />The general arrangement of the temporary facilities required for the raise bore <br />operation are shown on Map 42. A portable generator is required along with adjacent <br />fuel tanks. Primary containment for the fuel tanks will be through double wall <br />construction or the tanks will be placed in a containment area. The containment will be <br />lined with a suitable PVC material and the volume of the containment will be large <br />enough to contain the entire volume of the fuel tank plus 3 inches of freeboard for <br />precipitation. All facilities are in excess of 100 feet from Terror Creek so refueling or <br />lubricating will not take place within 100 feet of wetlands or other water bodies. <br />Refer to Map 42 for a plan view that shows the equipment that will be permanently <br />installed at the shaft site. The proposed shaft site is approximately 350 feet measured <br />horizontally and 120 measured vertically from Terror Creek. <br />The proposed shaft site is not within any congressionally designated areas, such as <br />wilderness, wilderness study areas, or national recreation areas. <br />Right of Entry <br />The shaft site is located on surface managed by the BLM. Right of entry on BLM <br />managed land is, subject to stipulations, authorized by Federal Coal Lease COC- <br />61209. <br />Affected and Disturbed Area <br />The construction site will disturb approximately 0.5 acres. The site was previously used <br />as a drill pad for TC-03-03 so there is approximately 0.5 acres of permitted disturbance. <br />There is no additional disturbance for this technical revision. Restoration of the site to <br />approximate original contour, distribution of topsoil and seeding are accounted for in <br />TR-25 and subsequent updated reclamation estimates. <br />Cultural Resources <br />See Volume VI, Cultural Resources, item 11. <br />Access <br />Access to the site will be via the Terror Creek access road approved by MR-116. <br />Soils <br />No detailed soil survey will be performed in the areas to be disturbed for the <br />construction site. To the extent possible, depending on the slope of the ground surface, <br />topsoil will be salvaged and stockpiled in the location shown on Map 42. <br />Vegetation
