and mining in Panels 12- through 20 -Left and 13- and 14 -Left Inby. Mine plan modifications under TR09-71 will include additional reserve areas in the WMD, with development and mining of the 19- and 20 -Left Panels from the 7- and 9 -North Mains. Alignment of development entries may be adjusted, as necessary, to address geologic conditions. Main and sub -main entries will be developed by continuous miner, as is current practice. WOLF CREEK RESERVE (WCR) WC (Development and Mining of Panels WC-4RT (east) through 9RT, TR13-83, PR15-11) TR13-83 addressed the initial development activities necessary to access and develop the Wolf Creek Coal Seam reserves, which underlie portions of the EMD and NMD. Initial development activities specifically include development and placement of long-term support for a 3 -entry rock -slope access, development of up to six sets of gate -roads and bleeder entries to support future longwall development (Panels WC-7RT through 9RT), and related ancillary activities, including underground dewatering activities and extension of mine ventilation and support systems. Subsequent development of controlled reserves (Panels WC- 4RT through 6RT (east)), mining of both the initial development areas, and the remaining controlled reserves (Panels WC-6RT through 4RT (east) and 7RT through 9RT), development of an internal ventilation and utility shaft, related ancillary operations, and adjustment of the eastern permit boundary are addressed under PR15-11. Development of the WCR will occur in parallel with ongoing mining in the WMD, with a combined annual production of up to 9 million tons. The rock slope to access the WC Reserve will be driven from the existing 5 - Main North Entries approximately 670 feet down to the Wolf Creek Coal Seam at a 12 percent grade. The first 130 feet of the rock -slope will include steel arch supports and a multi -plate liner for supplemental support. The remainder of the rock -slope will be driven in competent rock using conventional supports (resin -grouted roof bolts and steel mesh). TC owns or controls through valid existing leases, both the coal and the overlying surface in the areas to be affected by the proposed development and mining of the WCR. Development will be initiated in the existing State Coal Lease (CO -3229), with most of the development occurring in either this State lease or in TC's fee coal reserves. Subsequent development and mining will include portions of the State lease and TC's fee reserves, as shown on Map 23WC. Alignment of development entries may be adjusted, as necessary, to address geologic conditions. Main and sub -main entries will be developed by continuous miner as is current practice, and mining will progress using TC's existing longwall mining system, with 985 -foot wide panels, extending from 4,200 to 13,400 feet. (2) Operation Description The general operation plan for the Foidel Creek Mine is shown on Map 23, Mine Plan. This map shows the planned schedule for the mine advance throughout the current permit term. Separate five-year renewals will be obtained and incremental performance bond will be posted, as necessary and appropriate. The permit area associated with the underground coal mine encompasses approximately 22,607 acres. Total permitted disturbance acreage is approximately 734.2 acres. As shown on Maps 1 and 2, there are three remaining parcels of un -leased federal coal within the Mine Permit Area.. located in Section 33, T6N, R86W and Sections 22 and 23; T5N. R86W. In addition, the original federal :;oat lease (COC -51608) in Sections 21 and 22, T5N, R86W does not include the Wolf Creek Coal Scant. The BLM controls the coal within these areas, and the surface of the parcel of land located in the SWIX4 Ski'':,! Sectioi: T6'�_ RR6W it is not anticipated that the federal_ coal_ in '%ection T6N.

In February 2009, TC obtained the Federal Coal Lease from the BLM for the previously un -leased federal coal in Sections 22 and 27 of T5N, R8 7 W, and incorporated portions of these areas in the final Phase i1I urine development and longwall mining plans (under TR09-68 and PR09-08).
