Enclosure 1 <br />Item 1 <br />43 CFR 3482 regulations (c) (1) through (c) (7) detail certain Mineral <br />Leasing Act (MLA) requirements in regard to the resource recovery and <br />protection plan that must be a part of a mine permit application <br />package. Except for the following inadequacies, the Seneca II-W Mine <br />Permit Application seems to adequately address these requirements based <br />on our review and analysis. <br />A) 43 CFR 3482.1 (c) (3) (iii) "An estimate of the coal reserve <br />ase, mina a reserve ase, and recoverable coal reserves for <br />each Federal lease included in the resource recovery and <br />protection plan" (permit application). The coal tonnage values <br />are to be calculated based on the 43 CFR 3480.0-5 definitions. <br />For this application, the coal reserve base tonnages must <br />include all defined coal seams above an overburden depth of one <br />hundred (100) feet over the entire area of each lease. The same <br />one hundred (100) foot sublessee consideration applies to the <br />calculation of the minable reserve base and recoverable coal <br />reserve tonnages within the designated minable areas. An <br />additional map should be provided that shows the area(s) <br />corresponding to the coal reserve base lease tonnages. <br />Based on the designated areas to be mined as drawn on Map 12-1, <br />our geologists and mining engineers calculated the Wadge <br />recoverable coal tonnage to be 9,389,600. An average coal <br />thickness of twelve (12) feet, a coal density factor of 1,770 <br />tons/acre-foot, and a recovery factor of 95 percent were used in <br />this calculation. The application gives a life-of-mine <br />estimated tonnage of 8,369,700 which is 1,019,900 tons (10.9 <br />percent) less than our estimate. The applicant must provide <br />backup calculations of their recoverable coal reserve tonnages, <br />minable reserve base tonnages, and coal reserve base tonnages by <br />lease. <br />B.) 43 CFR 3482.1 (c) (4) (i) (D) "A plan map of the area to be <br />mine sowing t e o owing - coal outcrop." Three exhibit maps <br />labeled 6-1, 6-4, and 12-1 provide the location of what is <br />described as the Wadge coal seam outcrop or cropline. These <br />maps are in agreement. However, the exhibit geologic <br />cross-sections labeled 6-GX-5 and 6-GX-7 are not in agreement <br />~ for the bounded outcrop shown within the mining area along the <br />gulch that empties into sediment pond #006. The horizontal <br />distances transected on these cross-sections between outcrops <br />are signficantly less than that shown on the aforementioned plan <br />maps. The limits of mining shown for the Wadge on the <br />cross-sections approximate the lines referred to as outcrop or <br />cropline on the plan maps. Further, the exhibit labeled 12-5R3 <br />range diagram/cross-section depicts stripping to within fifteen <br />to twenty feet of overburden along this drainage. <br />
