6.4.5 Exhibit E -Reclamation Plan <br />Slope Grading <br />Phase I -Cells 2 and 3 and Phase II -Cells 1 and 2 combined will be reclaimed <br />to water storage reservoirs. Phase I -Cell 4 will become an unlined <br />groundwater-fed pond. All slopes will be graded to no steeper than 3H:1 V. The <br />required backfill material volumes to reclaim the slopes are presented in Table <br />6.4.5-2. <br />Table 6.4.5-2 Reclamation Earthwork <br />Reclamation Activity AREA APPROXIMATE Reclamation Sequence <br /> (acres) VOLUME <br /> AvailableNOLUME <br /> Required (yd') <br />Backfill: Phase I -Cell 1 As mining Phase I -Cell 1 <br />with overburden from 9.4 105,230/333,410 <br />Phase I -Cell 1 <br />Backfill: Phase I -Cell 1 As mining South and East <br />with overburden from 228 <br />180/333,410 Area of Phase I -Cell 2 <br />South and East Area of , <br />Phase I -Cell 2 <br />Backfill South portion and As mining North and West <br />slopes in Phase I -Cell 2 29.9 126,350/213,440 Area of Phase I -Cell 2 <br />to 3:1 <br />Backfill South portion and As mining Phase I -Cell 3 <br />slopes in Phase I -Cell 2 87,090/213,440 <br />to 3:1 <br />Backfill slopes in Phase I 13.7 650/145,260 <br />93 As mining Cell 3 <br />-Cell 3 to 3:1 , <br />Backfill slopes in Phase I 51 <br />610/145,260 As mining Cell 4 <br />-Cell 3 to 3:1 , <br />Grade Phase I -Cell 4 After mining Phase I -Cell <br />slopes to 3:1 with 13.1 75 <br />600/75 <br />600 4, and prior to mining in <br />material pushed from Cell , <br />, Phase II <br />4 pit floor <br />Topsoil replacement on 31.3 25,270 Following slope backfill <br />Phase I <br />Seeding and fertilizing of Following topsoil <br />Phase I 31.3 replacement, and prior to <br /> mining Phase II <br />November 16, 2006 Bokelman/Walters Pit <br />Page 8 of 36 Regular 112 Permit Application <br />
