reclaimed. However, it is not shown as part of the reclamation plan or bond for the 2004 amendment. <br /> Of the 28.7 disturbed acres in the north mine area, 2.8 acres will remain as ponds and 2.8 acres will <br /> remain as roads, therefore, only 23.1 acres will require the substitute fines. Using a 4.5" average <br /> thickness, this requires 13,976 cy. This volume will have been stockpiled at either of the two <br /> locations (Piles #1 and #2) and is also the volume that will be required to be spread at the end of the <br /> mine life. <br /> Therefore, at the end of the mine life, final grading will be needed on 23.1 acres, followed by topsoil <br /> (substitute fines) replacement and revegetation on the same areas. All portable buildings and tanks will <br /> be removed except for the shop/office building constructed near the pit entrance. This building and <br /> associated parking area will remain for commercial use after reclamation. <br /> The following table shows the tasks for full reclamation of the gravel pit area. <br /> Gravel Pit Reclamation Timetable <br /> Task# Description Time Needed <br /> in months <br /> 1 Regrade and reseed old 110 area while mining is active in 3.0 <br /> north reserve area. <br /> 2 Mine North Area while processing gold mine tailings.
