be daylighted to the natwal slope in the azea of the old Metcalf Pit. The slopes which are left in <br />Phases 12 and 13 are the only slopes throughout mining which will be mined at a 3H:1 V slope. This <br />will be done in order to minimize the amount of work required for reclamation at the end of the <br />minelife. Note that the Bean house which is in the southeast corner of the permit area next to Phase <br />12 will remain after mining; there will not be any impact on the structure due to mining. <br />The mining of the entire permitted azea is expected to last for 32 yeazs and will mine approximately <br />13.7 million tons of gravel from 182.6 acres. As seen on Map C-2, a natural berm will be left during <br />mining on the eastern boundary of the pit in order to visually screen the mining operation from the <br />east, as well as contain any rain events. Along the north, west and south edges of the mining <br />boundary, a 8 to 12 foot topsoil berm will be created for a visual screen azound the remainder of the <br />pit. <br />Mining of the Phases will be sequenced such that a maximum of six Phases will be active while <br />Stages A and B are being mined, and a maximum of three Phases during Stage C. While one Phase <br />is being mined, the next Phase will be stripped of topsoil and overburden and the Phase which has <br />been previously mined will be reclaimed with the overburden and topsoil from the Phase which is <br />currently being mined. This will reduce material handling as well as reduce the maximum azea to be <br />reclaimed. Fines from the crushing and screening operations will be salvaged and will also be used <br />in reclamation. The expected mining life for each of the Phases is included below in Table D-2. A <br />more detailed description can be found in Section five of the mining plan. <br />Haldorson Sand and Gravel Mine 10 <br />
