Topsoil Volumes Available <br />Topsoil volumes are calculated from pre -mine sample points. The calculations are shown on Map <br />2.05.4 -6 (Table A). If there is excess topsoil salvaged, it will be placed in the appropriate zone based <br />on the topsoil needs of the reclamation plan at that time. This potential excess is not included in any <br />of the topsoil balance calculations in order to be conservative in planning topsoil placement. The <br />remaining area to be stripped in front of the active disturbance is as follows: <br />Lift A Topsoil <br />Lift A: 29.3 acres - 3.19 acres already stripped for Pond 013, = 26.11 acres. <br />Lift A volume available from additional stripping = 26.11 acres x 9 inches avg. thickness = 31,593 <br />cy. The total Lift A available is 31,593 cy (from new stripping) + 146,337 cy from Stockpile #11 = <br />177,930 cy. Lift A Topsoil in front of the June 2010 active pit will be combined with stockpiled Lift A <br />Topsoil and spread over the 54.33 acres of Zone 4 to attain a thickness of 24 inches. <br />Stockpile #14 will also be created from final cut stripping, which will be approximately 35,450 cy, <br />which will be used to reclaim Zone #4. <br />A small stockpile of Lift A material will remain after final backfilling and filling to reclaim Pond 011, as <br />shown on Map 2.05.4 -6. This is Stockpile #18, which will contain approximately 7,250 cy. <br />Lift B Topsoil <br />Lift B: 29.3 acres - 3.19 acres (pond 013) + 1.72 acres additional area on east edge of stripping <br />area = 27.83 acres. <br />The remaining Lift B Topsoil to be stripped in front of the June 2010 active pit = 27.83 acres x 46 <br />inch average thickness = 172,113 cy. <br />The total Lift B available is 172,113 cy (from new stripping) + 221,516 cy from Stockpile #12 = <br />393,629 cy. Lift B Topsoil in front of the June 2010 active pit will be combined with stockpiled Lift B <br />Revised PR 06 June 10 2.05.4(2)(d) -32 <br />
