Most of the deposit to be recovered under this permit is old placer dredge tailings. There is no <br /> recoverable topsoil on these portions of the site. In the previously undisturbed portions of the site, <br /> topsoil will be stripped for use in reclamation. Topsoil and overburden in the undisturbed areas <br /> ranges from 6 to 18 inches thick. Topsoil and overburden will be stored in berms(Map C-2) for <br /> portions of the mine's life. Any topsoil or overburden storage berm will be vegetated within 180 <br /> days of completion. Table D-3 shows the topsoil stripping that will take place at each step of the <br /> mining operations, as shown on Maps C-2, C-3, and CA <br /> Table D-3 Topsoil Stripping Areas (Dredge Mining Stage) <br /> AOI Area Topsoil Present <br /> Partial Dredge Mining(Map C-2) <br /> Dredge piles J-62.9 Acres N <br /> Non-dredge area 22.4 Acres Y <br /> Full Mining(Map C-3) <br /> Dredge piles 211 Acres N <br /> ..... ..- -- <br /> Non-dredge area 142.6 Acres Y <br /> Overburden is not anticipated in the dredge pile areas based on site inspections. Overburden may be <br /> present in the non-dredge area, and will be placed as backfill in the final reclaimed mine. <br /> 5. Flocculant Use <br /> The Trout Valley Ranch may use flocculant at times in order to improve the recycling of wash <br /> water in processing. Flocculant is used in the water recirculation systems in mining operations that <br /> involve significant material washing. The use of flocculant expedites the drop-out of sediment in <br /> process waters within recirculation ponds. Several nearby placer mines in the area already use <br /> flocculants to improve water recycling in their operations. <br /> 5_1 System Design <br /> A water tank will be set up adjacent to the recirculation pond, wherever it is placed in the permit <br /> area. A drum of the Hyperfloc chemical will be set up next to the water tank and the Hyperfloc <br /> chemical and water will be pumped from both tanks using small pumps into a separate mixing tank <br /> as needed to allow the proper mixing concentration.
