under COC -54608 for Sections 21, 22, and 23, T5N, R96W in conjunction with future mining plans for the Wolf <br />Creek reserve. <br />Map 23A identifies previously mined areas, and delineates active and planned future mining areas at a more <br />detailed scale. Evaluations of projected subsidence and related effects, initially based on subsidence modeling, and <br />subsequently confirmed by actual mining and subsidence monitoring experience, indicate that subsidence would <br />not significantly impact the designated AVF or related environmental values. For actual and potentially impacted <br />portions of the designated Fish Creek AVF, the subsidence evaluation approach and conclusions are documented by <br />Exhibits 7B, 7C, 45 and 46 and by appropriate revisions to Exhibit 14. <br />The subsidence monitoring network for the longwall area is shown on Map 23A. Mapped subsidence survey lines <br />include the supplemental monitoring stations to be established for evaluation of potential subsidence impacts in the <br />effected portion of the designated Fish Creek AVF. <br />SOUTHWESTERN MINING DISTRICT <br />TC, through the acquisition of the un- leased federal coal reserves located in the SWMD, added additional <br />recoverable reserves to its existing mine plan. The SWMD lease application was submitted to the BLM on January <br />27, 1992, and was subsequently approved. <br />The lease application area is located in the N1 /2 of Section 36, T5N, R87W, and the W /2NR/4 and the NW /4 of <br />Section 31, T5N, R86W. The lease application comprises approximately 537 acres. The surface of this coal is <br />controlled by three different landowners, TC, Robert Perry, and Robert Perry et al. <br />TC extended the 2- and 3- Southwest Panels to the west. The 2- Southwest Panel was extended approximately 300 <br />feet to the west and the 3- Southwest Panel was extended approximately 700 feet to the west. The modified mine <br />projections are shown on Maps 23 and 23A, Mine Plan. The panel extensions allowed for the recovery of <br />additional reserves in the newly acquired federal lease. <br />MR 14 -282 2.05 -3.1 09/02/14 <br />
