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 (Test Excavation, Initial Support, and Staging MR14 -282) TC will complete test excavations and installation of initial support for the WC rock - slopes 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. The test excavations will extend no more than 30 feet below the bottom of the current 5 Main North Mains mine in the Wadge Coal Seam as shown by Figure EX54 -F 1 in Exhibit 54, Wolf Creek Reserve Construction and Development Plans. Dependent on the conditions encountered and the information gained from the test excavations and the initial support installation, TC may then stage critical materials for the subsequent rock - slope construction activities. (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 22,447 acres. Total permitted disturbance acreage is approximately 660.4 acres. As shown on Maps I 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 existing federal coal lease (COC- 54608) in Section 21, T5N, R86W does not include the Wolf Creek Coal Seam. The BLM controls the coal within these areas, and the surface of the parcel of land located in the SW' /4 SW' /4 Section 33, T6N, R86W. It is not anticipated that the federal coal in Section 33, T6N, R86W will be mined, since it is in an area where the coal seam dips steeply upward on the edge of the synclinal basin. 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, R87W, and incorporated portions of these areas in the final Phase III mine development and longwall mining plans (under TR09 -68 and PR09 -08). TC is pursuing leasing of the federal coal and inclusion of the Wolf Creek Seam M R 14 -282 2.05 -3 09/02/14
