and mining in Panels 12- through 20-Left and 13- and 14-Left Inby. Mine plan modifications under TR09-71 will
<br /> include additional reserve areas in the WMD, with development and mining of the 19- and 20-Left Panels from the
<br /> 7- and 9-North Mains. Alignment of development entries may be adjusted, as necessary, to address geologic
<br /> conditions. Main and sub-main entries will be developed by continuous miner, as is current practice.
<br /> WOLF CREEK RESERVE (WCR)
<br /> WC (Development and Mining of Panels WC-5RT through 9RT,PR14-10,PR15-11,TR13-83,TR18-92)
<br /> TR13-83 addressed the initial development activities necessary to access and develop the Wolf Creek Coal Seam
<br /> reserves, which underlie portions of the EMD and NMD. Initial development activities specifically include
<br /> development and placement of long-term support for a 3-entry rock-slope access, development of up to
<br /> six sets of gate-roads and bleeder entries to support future longwall development (Panels WC-7RT
<br /> through 9RT), and related ancillary activities, including underground dewatering activities and extension
<br /> of mine ventilation and support systems. Subsequent development of controlled reserves (Panels WC-
<br /> 5RT and 6RT), mining of both the initial development areas, and the remaining controlled reserves
<br /> (Panels WC-5RT through 9RT), development of an internal ventilation and utility shaft, related ancillary
<br /> operations, and adjustment of the eastern permit boundary are addressed under PR14-10 and PR15-11.
<br /> Extension of the 7-East Panel (designations changed from WC-7RT to avoid confusion with Wadge Seam
<br /> panel designations) is addressed by TR18-92.
<br /> Development of the WCR will occur in parallel with ongoing mining in the WMD, with a combined annual
<br /> production of up to 9 million tons. The rock slope to access the WC Reserve will be driven from the existing 5-
<br /> Main North Entries approximately 670 feet down to the Wolf Creek Coal Seam at a 12 percent grade. The
<br /> first 130 feet of the rock-slope will include steel arch supports and a multi-plate liner for supplemental
<br /> support. The remainder of the rock-slope will be driven in competent rock using conventional supports
<br /> (resin-grouted roof bolts and steel mesh). TC owns or controls through valid existing leases, both the coal and
<br /> the overlying surface in the areas to be affected by the proposed development and mining of the WCR.
<br /> Development will be initiated in the existing State Coal Lease (CO-3229), with most of the development occurring
<br /> in either this State lease or in TC's fee coal reserves. Subsequent development and mining will include portions of
<br /> the State lease (CO-3229), Federal reserves (COC-54608), and TC's fee reserves, as shown on Map 23 WC.
<br /> Alignment of development entries may be adjusted, as necessary, to address geologic conditions. Main and sub-
<br /> main entries will be developed by continuous miner, as is current practice, and mining will progress using TC's
<br /> existing longwall mining system, with 985-foot wide panels, extending from 4,200 to 13,400 feet.
<br /> (2) Operation Description
<br /> The general operation plan for the Foidel Creek Mine is shown on Map 23, Mine Plan. This map shows the
<br /> planned schedule for the mine advance throughout the current permit term. Separate five-year renewals will be
<br /> obtained and incremental performance bond will be posted, as necessary and appropriate. The permit area
<br /> associated with the underground coal mine encompasses approximately 22,607 acres. Total permitted disturbance
<br /> acreage is approximately 734.2 acres.
<br /> As shown on Maps 1 and 2, there are three remaining parcels of un-leased federal coal within the Mine Permit
<br /> Area., located in Section 33, T6N, R86W and Sections 22 and 23, T5N, R86W. In addition, the original federal
<br /> coal lease (COC-54608) in Section 21, T5N, R86W does not include the Wolf Creek Coal Seam. The BLM
<br /> controls the coal within these areas, and the surface of the parcel of land located in the SW'/4 SW'/4 Section 33,
<br /> T6N, R86W. It is not anticipated that the federal coal in Section 33, T6N, R86W will be mined, since it is in an
<br /> area where the coal seam dips steeply upward on the edge of the synclinal basin. In February 2009, TC obtained
<br /> the Federal Coal Lease from the BLM for the previously un-leased federal coal in Sections 22 and 27 of T5N,
<br /> R87W, and incorporated portions of these areas in the final Phase III mine development and longwall mining plans
<br /> (under TR09-68 and PR09-08). TC is pursuing leasing of the federal coal and inclusion of the Wolf Creek Seam
<br /> under COC-54608 for Sections 21, 22, and 23, T5N, R86W in conjunction with mining plans for the Wolf Creek
<br /> TR18-92 2.05-3 12/11/18
