Eight (8) coal beds have been identified within the boundary of the Deserado Mine proposed LMU. These eight (8) beds are listed below in ascending order. • Iles • B Seam • D Seam • E Seam • F Seam • G Seam • H Seam • J Seam Although all eight (8) seams are correlatable over at least a portion of the proposed LMU, only the D and B Seams are thick enough over a large enough areal extent to be considered mineable. The cross sections (Plates 4, 5 and 6) in the R2P2 show the stratigraphic relationship of the eight seams. Table I is a summary by lease of the coal reserve base for all eight seams in the proposed LMU. Table II is a summary of the mineable reserve base; and Table III is a summary of the recoverable raw coal reserves, and the recoverable clean coal reserves (see R2P2 Section 4.3 for definitions). A clause in lease C-0126669 restricts mining within 100 feet of the 100 year flood plain of the White River. That clause cuts off mining of that portion of C-0126669 under and south of the White River. It is logical to connect lease COC 51551 with the existing LMU to form a new LMU I, to achieve maximum economic recovery (MER) through a well planned and coordinated mining operation in the D Seam. The LMU will facilitate the I' development and extraction of the D Seam by the longwall mining method in lease COC 51551 area. A separate development and mining of lease COC 51551 is not economically practical. Plate 7 shows the D Seam mine plan for the proposed LMU. I, I, i~ r 4
