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 deveoped by continuous miner, as is current practice. (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 life of the mine. 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 22,450 acres. Total permitted disturbance acreage is approximately 609.4 acres. As shown on Maps 1 and 2, there is one remaining parcel of unleased federal coal within the mine Permit Area., located in Section 33, T6N, R86W. The BLM controls the coal within this area, and the surface of the parcel of land located in the SWl /a SWl /a 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, TCC obtained the Federal Coal Lease from the BLM for the previously un- leased federal coal in Sections 22 and 27 of TSN, R87W, and will incorporate final Phase III mine development and longwall mining into the proposed mining plans (under TR09 -68 and PR09 -08). Map 23 presents previously mined, active, and planned future mining areas. Evaluations of projected subsidence and related effects, initially based on subsidence modeling, and subsequently confirmed by actual mining and subsidence ' monitoring experience, indicate that subsidence would not significantly impact the designated AVF or related environmental values. For actual and potentially impacted portions of the designated Fish Creek AVF, the subsidence evaluation approach and conclusions are documented by Exhibits 713, 7C, 45 and 46 and by appropriate revisions to Exhibit 14. • The proposed subsidence monitoring network for the longwall area is shown on Map 23C. Mapped subsidence survey lines include the supplemental monitoring stations to be established for evaluation of potential subsidence impacts in the effected portion of the designated Fish Creek AVF. • SOUTHWESTERN MINING DISTRICT TCC, through the acquisition of the un- leased federal coal reserves located in the SWMD, added additional recoverable reserves to its existing mine plan. The SWMD lease application was submitted to the BLM on January 27, 1992, and was subsequently approved. The lease application area is located in the N1 /2 of Section 36, TSN, R87W, and the W /2NR/4 and the NW /4 of Section 31, TSN, R86W. The lease application comprises approximately 537 acres. The surface of this coal is controlled by three different landowners, TCC, Robert Perry, and Robert Perry et al. TCC extended the 2- and 3- Southwest Panels to the west. The 2- Southwest Panel was extended approximately 300 feet to the west and the 3- Southwest Panel was extended approximately 700 feet to the west. The modified mine projections are shown on Maps 23, 2313, and 23C, Mine Plan. The panel extensions allowed for the recovery of additional reserves in the newly acquired federal lease.
