• Future Permit Areas <br />It is anticipated that a permit renewal application will be submitted each five years, prior to the <br />expiration date of the permit currently in force. Those areas to be permitted for mining and reclamation <br />under subsequent five-year permits are identified by year on the Operations Plan and Reclamation Plan, <br />Exhibits 12-2 and 12-3 and 19-1 and 19-1A. This assumes that, for ease of identifying areas, 1990 is <br />not counted as a Lull year. The first full five-year term was 1991 through 1995. Subsequent five-year <br />permit applications have been or will be submitted for the years 1996 through 2000, 2001 through <br />2005, etc. The permit area is described in Tab 3 of this application. <br />Coal Resource Protection and Conservation <br />Mining at Seneca II-W involves extraction of a multiple coal seam having varying overburden depths. <br />The initial choice of mining equipment type and size was based upon the type of mining conditions, <br />production requirements, the life of the mining operation, types and thicknesses of overburden, local <br />and regional dip, and thickness of the coal seam. Experience in mining at Seneca 11-W has resulted in <br />the anticipated mix of excavation and support equipment. Auxiliary equipment has been matched to <br />the primary excavator and its capabilities. Mining activities are conducted to maximize the recovery of <br />• coal while maintaining environmental integrity. <br />During reserve development, all the coal encountered during drilling is recorded. The correlatable and <br />estimated mineable seams are cored and analyzed. These data are utilized to finally determine mineable <br />reserves. The quality of the seams as well as their occurrence in the geologic column is considered <br />when determining whether the seam is mineable or nonmineable. <br />The design of the cut widths are based upon the machine performing the excavation to prevent the pits <br />from becoming too wide resulting in spoil material being placed on uncovered coal and leaving coal <br />fenders. Sloughing of spoil material onto uncovered coal is anticipated to occur infrequently. If <br />sloughing should occur, auxiliary equipment will be utilized to remove the spoil material so that the coal <br />can be removed. All coal tenders will be mined. Negligible amounts oT coal should be lost because of <br />either of these two conditions. Further, it is in the operators best interest to recover the maximum <br />amount of coal possible once the overburden has been removed and the coal seam exposed. <br />The efficiency of the mining operations can be measured by the number of tons of coal produced per <br />acre toot (TPAF1. Based on drill hole data regarding seam thickness, coal partings, and extent and <br />laboratory analysis of specific gravity 11.301, in-place reserves are estimated to be 1,762 tons per acre <br />foot. Actual production will be calculated monthly using scale measurements and stockpile <br />• fluctuations. This production would be defined through the use of monthly aerial or engineering <br />surveys to an area where coal was actually removed to produce the TPAF recovered Tor each month. <br />The historical average recovery for the Seneca II-W mine is approximately 93.6 percent.
