Loggerhead shrike (L.anius ludovicianus), Federal category 2 species, use has not been <br /> recorded on the study area, although potential breeding and nesting habitat is present. <br /> Loggerhead shrikes are dependent upon sagebrush and gambel oak shrub communities for <br /> breeding and nesting habitat in this region during spring and summer. They are uncommon in <br /> 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 /> 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 lease block <br /> consists of minable coal reserves in five Federal coal leases, one private lease and other fee <br /> coal properties. Together the leases encompass approximately 15,500 acres. <br /> Six major coal seams exist on the West Elk Mine property. The seams are identified by letter <br /> with the A Seam being the lowermost and the F Seam the uppermost. The intervals between <br /> the seams vary from as little as 15 feet to more than 250 feet. <br /> The economically minable coal reserves in these leases occur in two of the six seams (the E <br /> and B Seams). The B Seam has been mined and the E Seam is planned to be mined in Lease <br /> D-044569; the B Seam has been mined in Leases COC-54558 and C-0117192, where mining <br /> continues; the plan is to mine the B Seam in Lease COC-56447; and further B Seam and E <br /> Seam are planned for mining, in Lease C-1362. The B-seam will be mined in those portions of <br /> Leases COC-56447 and C-1362 that comprise the Box Canyon Permit Revision area added <br /> with PR-08. <br /> Mountain Coal Company mined in the F Seam from 1982 to 1991 from Lease D-004569 and <br /> C-0117192. This mining was only marginally successful. Poor mine roof conditions, <br /> sandstone channels, low coal areas, poor coal quality areas, and other unfavorable conditions <br /> have negatively affected mining and rendered this seam uneconomic under past and present <br /> market conditions. <br /> Approximately 180 feet below the F Seam horizon lies the E Seam. Mining plans in the <br /> E-Seam are presented on Map 51. Mountain Coal Company believes the E Seam can be mined <br /> without precluding mining of the B Seam. This conclusion is based on experience gained by <br /> the Mountain Coal Company since opening the West Elk Mine, recent geotechnical analyses, <br /> and advances in mining technology. The E Seam in the west panels of the Apache Rocks <br /> Permit Revision area is planned to be mined prior to the B Seam panels beneath. <br /> Approximately 400 feet below the F Seam and 200 feet below the E Seam lies the B coal seam. <br /> The minable B Seam contains some areas of coal, particularly in Federal Leases C-0117192, <br /> COC-54558, and COC-56447, where no minable E Seam exists above the B Seam. Also, in a <br /> portion of C-0117192, the F Seam is mined out. In these areas, there is B Seam minable <br /> reserves which, when mined, will not significantly affect the minability of the other seams. <br /> 16 <br />
