The technical revision address changes in the post-mining <br />topography. <br />As you are aware, EFCI has recently updated the their base maps using topography developed from atrial <br />surveys. Given the existing revised topography in the facilities area, EFCI has reevaluated the post-mining <br />topography. The revised post-miming topography has not changed significantly, however, the volume of <br />material requiring handling and placement was reduced from 55,000 to 50,000 cubic }~ards. The 50,000 cubic <br />yards includes approximately 5,000 cubic yards for any coaly material which may require disposal. In addition, <br />the avenge distance bebveen cut mid fill areas is approximately 400 feet, which suggests that the material in the <br />facilities area can be moved using dozers rather than scrapers. Final grading of Ponds 3 and 4 will require <br />handling and placement of approximately 21,000 cubic yards. The current bond calculations asswne 17,800 <br />cubic yards. <br />Included with the transmittal are the following: <br />• Application for Technical Rcvision <br />• Public Notice <br />• Summarv of Revisions and Additions <br />• Revised Permit Text <br />• Rcviscd Pemlit Maps <br />ICyou have any questions or required further information please contact AI Weaver or myself. <br />Sincerely, <br />TcrraMn[rix Inc. 3' <br />C7L~ G oCy~~~^~ <br />Thomas E.
