Mining Operations <br /> Phasing <br /> Mining would be divided into eight phases beginning with Phase I. While mining Phase I, the Phase VII <br /> area would be temporarily bermed to create a silt pond using Phase I overburden. Once mining is <br /> completed in Phase I, it would be used for permanent silt containment and the silt temporarily contained <br /> in Phase VII would be pumped into the Phase I silt pond. Mining would continue to Phase II, III, IV, and so <br /> on until all phases have been mined. If additional silt storage is needed during the course of mining, the <br /> Phase IV area would be used as a silt pond. Phase VIII will be mined once the structures including the <br /> aggregate plant are demolished and removed. The material excavated from Phase VIII will be processed <br /> by a portable plant located on the capped settling pond in the Phase I area. Revised Tables 3-1 and 3-2 <br /> describe the elements of the mine phases. <br /> Top Soil and Overburden Removal <br /> The total amount of top soil is approximately 800,000 cubic yards, an average of nine inches thick (i.e., <br /> 800,000 cubic yards over 659 acres). Topsoil would be stripped using scrapers and stockpiled in berms <br /> for use in landscape areas and final reclamation. The largest amount of topsoil stockpiled at one time <br /> would be approximately 50,000 cubic yards and will vary as new areas are opened up and others <br /> reclaimed. <br /> According to estimates included in Table 3-1, above, the total amount of overburden is approximately 6.6 <br /> million cubic yards. The overburden will be stripped by scrapers and stockpiled in berms, including the <br /> landscape berms, prior to use in reclamation. The berms will be located along the perimeter setbacks. <br /> San Joaquin County QX-01-2\Lonestar California <br /> Community Development Page 7 <br />
