EMD (Panels 2-Right through 6-Right, PR97-04) During the five-year permit term covered by this application, mining will continue in the Eastern Mining District. • Initial development of gateroads in the Eastern Mining District encountered a previously unidentified fault. Conditions associated with this fault required TCC to redesign the submains and mains; with their new locations as shown on Map 23. Development mining will occur in Gateroads 2-Right through 4-Right in the Eastern Mining District. Longwall mining will occur in Panels 6-Right through 2-Right in the remainder of the Eastern Mining.. These mining areas are shown on Map 23. Longwall Panels 6-Right through 2-Right will involve mining of coal contained in Federal leases COC-54608, C- 081330, and D-052543, and fee coal owned by TCC. Development of Gateroads 4-Right through 2-Right will involve mining coal from Federal lease COC-54608, and fee coal owned by Twentymile. Development of the Northeast Submains will involve mining of coal from Federal leases C-081330 and COC-54608. NMD (Pane112-Right through 16-Right, PR99-OS7 During the five-year permit covered by the application (1998-2003), mining will continue in the Eastern Mining District (as approved in Permit Revision PR97-04) and progress into the Northern Mining District. Development mining will continue in Gateroad 11-Right through 18-Right, the Northeast and Northwest Mains, and Longwall Panels 12-Right through 16-Right. The mining area is shown on Map 23. Mining of Longwall Panels 12-Right through 16-Right will involve mining of coal from Federal lease COC-54608, State lease CO-3229, and fee coal owned by TCC. Gateroads 11-Right through 18-Right will involve mining coal from the same leases as described for the longwall panels. In the Northeast Mains, in addition to Federal lease COC-54608, and State lease CO-3229, coal will be mined from the Myron Walker Trust lease. • NMD (Pane117-Right through 21-Right, PR03-06) During 2003-2008, mining will continue in the Northern Mining District. Development mining will continue in Gateroads 18-Right through 24-Right, the bleeders, the Northwest Mains, and Longwall Panels 17-Right through 22- Right (partial). The mining area is shown on Map 23. Mining of Longwall Panels 17-Right through 22-Right will involve mining of coal from State lease CO-3229 and fee coal owned by TCC. Gateroads 18-Right through 24-Right and the associated bleeders will involve mining coal from the same leases as described for the longwall panels. The Northwest Mains will mine coal from State lease CO-3229. NMD (Panel 21-Right through 24-Right (partial)) and WMD (Panel 15-Left through 18-Left (preliminary development)) - PR06-07, TR07-63 During 2006-2008, mining will continue in the Northern Mining District. Development mining will continue in Gateroads 21-Right through 24-Right, the bleeders, the Northwest Mains, and Longwall Panels 21-Right through 24- Right (partial). The mining area is shown on Map 23. In preparation for future mining in the Western Mining District (WMD), TCC will proceed with initial development of the main and submain entries for Panels 15-Left through 18-Left. Alignment of development entries maybe adjusted, as necessary, to address geologic conditions. Mining of Longwall Panels 21-Right through 24-Right will involve mining of coal from State lease CO-3229, fee coal, owned by TCC, and federal coal to be obtained by TCC (federal lease sale scheduled for October 6, 2006). Gateroads 18-Right through 24-Right and the associated bleeders will involve mining coal from the same leases as described for the longwall panels. The Northwest Mains will mine coal from State lease CO-3229 and fee coal owned by TCC. Preliminary development in the Panel 15-Left through 18-Left mains and submains will involve mining of coal from .State lease CO-3229. TR07-63 2.05-7.1 09/14/07
