Loggerhead shrike (Lanius ludovicianus, a Federal category 2 species), use has not been recorded <br />on the study area, although potential breeding and nesting habitat is present. Loggerhead shrikes <br />are dependent upon sagebrush and gambel oak shrub communities for breeding and nesting <br />habitat in this region during spring and summer. They are uncommon in the area during winter. <br />For specific information regarding study areas, methods for identification and counting of the <br />various wildlife present in the area, see Section 2.04.11 of the permit document. <br />Additional information on fish and wildlife in the PR -14 project area is contained in the copy of <br />the Federal Environmental Impact Statement for the Deer Creek Shaft and E Seam Methane <br />Drainage Wells Project which can be found in Exhibit 79 of the permit application. <br />Description of the Operations and Reclamation Plan - Rule 2.05.3 and 2.05.4 <br />Mining at the West Elk underground mine began in 1982. The West Elk Mine leasehold consists <br />of mineable coal reserves in six Federal coal leases, one private lease and other fee coal <br />properties. The mine permit area encompasses approximately 17,155 acres. Current coal <br />production ranges between 6.5 and 7 million tons per year using the longwall mining method. <br />Six major coal seams exist on the West Elk Mine property. The seams are identified by the <br />letters A through F, in ascending stratigraphic order. The seams are separated by shale, siltstone, <br />and sandstone beds that vary in thickness from 15 feet to more than 250 feet. MCC's leasehold <br />has economically minable coal reserves in two of the seams, the B Seam and the E Seam. <br />Mining was by room - and - pillar methods until 1990 when longwall mining began in the B Seam. <br />The mine plan for the B Seam is shown on Map 52 of the permit application. MCC has <br />completed mining in the B Seam in the following four leases: D- 044569, COC- 54558, COC- <br />0117192, and C -1362. As of early 2008, MCC was longwall mining the B Seam in the Box <br />Canyon portion of lease COC -56447 (approved in PR -08) and maintains active development <br />entries in a fee lease area in Sylvester Gulch in Section 15- T13S -R9OW (approved in TR -107). <br />B Seam mining has previously been approved for COC -67011 (PR -11), located in the West <br />Flatiron area. There are B Seam mineable reserves in a portion of C- 0117192 where the F Seam <br />is mined out. <br />The mine plan for E Seam is shown on Map 51 of the permit application. As of late 2008, MCC <br />maintains active development entries in the E Seam in leases COC- 56447, D- 044569, and C- <br />1362. These entries will provide access to E seam longwall panels 1 through 9 that are to be <br />mined in lease C -1362 in the South of Divide area, as approved in PR -10. MCC will access the <br />E seam in the South of Divide (PR -10) area and Dry Fork lease (PR -12) area through the mine's <br />existing F to B seam slopes and will utilize the existing surface facilities near State Highway <br />133; consequently, no additional surface facilities or associated surface disturbance were <br />proposed in PR -10 or 12. Surface disturbance and drilling of methane drainage wells in E Seam <br />panel 1 was approved in Technical Revision 111. E Seam mining of longwall panels 10, 11, and <br />12 was approved in PR -6 and is planned to occur prior to mining the underlying B Seam panels. <br />Mountain Coal Company mined in the F Seam from 1982 to 1991 in leases D- 004569 and <br />C- 0117192. This mining was only marginally successful. Poor mine roof conditions, sandstone <br />15 <br />
