quarry is expected to have 50-100 years of mine life. The Jefferson Quarry has been split into two <br />phases. The first phase of mining will start at the northern outcrop and progress downwards towards <br />the Lincoln Gallery. The second phase of mining will progress southward from the first phase. The <br />deepest parts of the Jefferson Quarry will not be mined until both the first and second phase of the <br />quarry have been initiated. Utilities for the Jefferson Quarry will be strung up the cliff face until a <br />bore has been placed to connect it to the infrastructure of the Lincoln Gallery. As the Jefferson <br />Quarry reaches its final depth a connection to the Lincoln Gallery may be installed. <br />Access to the Franklin Quarry will be initially developed along the access road to the sediment basins <br />at the foot of the Washington WRL. Waste blocks from the initial development of the Franklin <br />Quarry will be utilized to begin building the first bench of the Washington WRL and developing <br />access as seen in Map C-3. Phase 1 of the Franklin Quarry only mines the knob of material between <br />the small drainage and Yule Creek. This allows for the hydraulic isolation of the excavation from <br />upslope water inflow. The diversion ditch shown in C-2 and C-3 will be installed prior to mining in <br />Phase 2 of the Franklin Quarry. Specifics of the diversion are discussed in Exhibit G. The Franklin <br />Quarry is much smaller with 0.8 million cubic yards of marble. Its life is expected to be 20-30 years. <br />Future underground galleries within the deposit could extend the life of the mine further. <br />The Washington WRL is currently being used to accept all waste marble. The first bench of the <br />Washington WRL will begin being built during the development of the Franklin Quarry. Partial <br />backfilling of the Washington Gallery will occur during the development of the Washington WRL. <br />This backfill will improve the safety of the site and maybe used for access to reopen workings in the <br />Washington Gallery later in the mine's life. <br />The Jefferson WRL will be developed once mining begins in the Jefferson Quarry. Initial waste <br />marble will be utilized to develop the WRL access. Then the first bench of block walls will be <br />constructed utilizing waste blocks. Hydraulically broken waste marble will then be backfilled against <br />the wall. Stripping of trees and topsoil for the Jefferson WRL will occur in stages when necessary to <br />allow for waste storage. Trees are sold locally. The topsoil is very limited and includes a significant <br />amount of rock. While appropriate topsoil will be directly placed in areas that need revegetation, <br />however, the final land use does not anticipate revegetation over a majority of the disturbed areas. <br />Excess material will be placed in the WRL. <br />The Pride of America DRMS 112c <br />Exhibit D - 7 12/23/15 <br />
