1 <br />448,740 bcy. The permit maps (Appendix Q-1), showing the proposed and current AOCs, are <br />attached. <br />In summary, the revised LTSP overburden volume (448,740 bcy) was estimated using the Grid <br />method and the following two surfaces: <br />1. The October 2000 Facility Topographic Surface. This topographic surface is based on <br />aerial photography and topographic mapping conducted by Cooper Aerial Survey <br />' Company from Tucson, Arizona. <br />2. The Revised Bottom of Topsand Surface. This surface was based on the final <br />' reclamation grade defined in the 2000 AHR (Appendix Q-1, Reclamation Contour and <br />Drainage Plan Map). As described above, the LTSP final reclamation grade was <br />revised to increase by approximately 3 feet while maintaining drainage. The bottom of <br />' topsand surface is 15 inches below this revised final reclamation grade. <br />The TIN surfaces for the October 2000 topographic surface and revised LTSP bottom of <br />' topsand were defined in AutoCAD as "tp00" and "r-snd," respectively. Tetranext proposes to <br />provide all future LTSP overburden volumetric calculations using the Grid Method to estimate <br />the differential volume between the facility annual topographic surface and the revised bottom <br />' of topsand surface. <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />LJ <br />' " BE&K/TerraNeXt <br />
