[12.58 acres (Excludes the new and <br /> existing roads, and the PGM stockpiles)X 401.7 cyds in one acre, 3 inches deep= <br /> 5,062 cyds.] The existing PGM contains approximately 4,000 cyds of PGM. We <br /> will salvage an additional 1,062 additional Cyds of PGM from the area yet to be <br /> mined. <br /> The three soils units are Tassel Fine Sandy Loam, map symbol 61, approximate <br /> 7.8 acres, Weld Loam, map symbol 79, approximately 3.1 acres, and Colby <br /> Loam, map symbol 17, approximately 17.5 acres. However, given the extensive <br /> site disturbance,the NRCS soils unit descriptions are not accurate. We will <br /> therefore replace approximately 3 - 4 inches of PGM on the affected areas during <br /> site reclamation. <br /> Location of the plant growth material (PGM) stockpiles indicated on the Pre- <br /> mine/Mine Plan Map will protect the PGM pile from mining operations since they <br /> are out of drainageways. <br /> The location for the PGM stockpile and its access road are shown on the Pre- <br /> mine, Mine Plan Map. <br /> The entire area for PGM storage should be adequate as a temporary storage area. <br /> It is free of drainages and is somewhat flat. <br /> Given the short duration of the borrow operation, the PGM stockpile will not be <br /> seeded. The PGM stockpile will remain in a rough condition. Once borrow <br /> material is removed and final grading and discing (as needed) is complete,the <br /> PGM stockpile will be removed, and the PGM replaced on the final regrade. <br /> However, in the unlikely event the PGM stockpile is not used for site reclamation <br /> within one year, it will be seeded with the approved reclamation seed mix. The <br /> PGM stockpile location and its access road will then be reclaimed. <br /> (d) Specify the thickness of overburden or quantity of waste rock,if any, <br /> to be removed to reach the deposit. The location of any overburden <br /> stockpiles or waste rock fill must be shown on Exhibit E—Map: <br /> This mining operation is a borrow pit. Once the specified amount of PGM is <br /> removed, all excavated material will be used borrow material. <br /> (d) Specify the thickness of the deposit to be mined: <br /> Maximum mining depth is approximately seventy feet. We plan to remove up to <br /> one million cubic yards of material. However, the premine topography is very <br /> 47 <br />
