WESTERN MINING DISTRICT WMD (Panels 12 -Left through 20 -Left and 14- and 15 -Left Inby; PR06 -07, PR09 -08, TR07 -63, TR08 -64, TR09- 68, TR09 -71) During 2007 -2008, and the subsequent permit term (2008- 2012), mine development (Phase I, II, and Interim I1I) will progress in the WMD, with final Phase III development and actual longwall mining proceeding following approval of a permit revision application (PR09 -08) addressing these activities. In preparation for future mining in the WMD, TC will proceed with development of main and sub -main entries for Panels 13 -Left through 17 -Left. Alignment of development entries may be adjusted, as necessary, to address geologic conditions. Phase I through Interim Phase III development will result in extension of development in the 18 -, and 17 -Left gate - roads to their furthest western limit, partial development of the 16 -, 15 -, 14, and 13 -Left gate- roads, and full development of the 9- and 10 -North Mains. Development of the 18 -, 17- and 16 -Left gate -roads will extend into the new Federal coal lease (COC- 72980) at the western edge of the WMD. Under the full WMD development and mine plan modification approvals (PR09 -08 and TR09 -71) development of Gate -roads 12 through 20 -Left, 13- through 15 -Left Inby, the associated bleeder entries, and mining of Panels 12- through 20 -Left and 14- and 15 -Left Inby will involve mining coal from Federal Coal Leases COC -20900 (as modified June 22, 2007) and COC- 72980, State lease CO -3229, and fee coal leased by TC from NRC -CO 1, LLC, LLC. WOLF CREEK RESERVE (WCR) WC (Test Excavation, Initial Support, and Staging MR14 -282) In order to provide the necessary information to evaluate the construction and support plans for the rock - slopes, pillar response; and confirm the design parameters or provide the necessary information for modification of the plans to best meet site conditions and constraints, TC will complete test excavations and initial support installation. The test excavations will be advanced at the angle of the rock - slopes from the 5 Main North No. 2 Entry, extending no more than 30 feet below the base of the Wadge Seam, as shown on Figure EX54 -F1. Non -coal excavated material will be placed in the unused 5Main North rock -belt entry, and any coal excavated will be transferred to the coal product belt. The initial support installation will consist of a poured concrete floor and sill, with a pre- fabricated box culvert backfilled with compacted fill or flow -fill to the level of the floor of the overlying Wadge workings.
