With an average depth <br />of 4.0 feet, the capacity of the pond is 2.0 acre-feet. The topsoil from the excavation of Phase 1 <br />will be stored in a topsoil storage area along the north and east sides of the pit. Upon the <br />completed mining of Phase 3 any remaining topsoil will be used along the slopes in. Phase 3 and <br />to reclaim the sediment pond. <br />Table D-2 <br /> Minn Tonna a per Area <br />Phase Area (acres) Gravel (tons) Overburden (CY) Topsoil (CY) Life (months) <br />1 9.0 275,385 43,560 14,520 26.44 <br />2 9.6 329,246 46,464 15,488 31.61 <br />3 8.2 348,967 39,688 13,229 33.50 <br />Total 26.8 953,598 129,712 43,237 91.5 <br />Total ears) 7.63 <br />Mining will progress through the site from west to east. The topsoil and overburden from a new <br />area will be used to reclaim the previous area. This will reduce material moving as well as reduce <br />the maximum area to be reclaimed. Any fines from the crushing/screening operation will also be <br />salvaged and used in the reclamation. A table of expected mining lives for each phase is included <br />in Table D-2. The life of each phase is based on the anticipated annual average tonnage. This <br />does not include time needed to perform final reclamation. <br />Gehrman Pit October 09 D-2
