Once the deposit has been mined from the southern portion, the stockpile will be removed <br />from the northern portion and used for southem portion reclamation. The northern portion <br />will then be stripped and the overburden will be stockpiled on the pit floor of the <br />previously reclaimed southern portion. Once the northern portion deposit is mined the <br />overburden stockpiled in the southern portion will be used for reclamation. There will be <br />no permanent stockpiles on this site, all extra overburden will be used to create undulating <br />shorelines. The same method will be used for Phase II. <br />The deposit will be mined in two phases. The aggregate will be mined using front-end <br />loaders. Mined material will be loaded on a conveyor system for transport to Cottonwood, <br />an existing DMG permitted site (M-1988-042) located immediately south, for processing <br />with a portable screen and crusher. Additional conveyors maybe constructed inside the <br />mine areas to facilitate transport of the resource. The proposed conveyor crossing of WCR <br />20'/a will be an enclosed 100-foot span, 17-foot in height. The bridge is composed of steel, <br />the footings are anchored in concrete. The conveyor bridge is currently in use at our <br />Tanabe pit (M-2000-002), see enclosed Proposed Overhead Conveyor and Conveyor Belt <br />Bridge Piers drawings for specifics. When mining operations are complete, the conveyor <br />will be removed and all areas affected by the conveyor will be restored to their original <br />condition. <br />Lafazge will maintain mining offsets equal to 3 times the pit depth, or 60 feet, from all <br />structures. This offset will include an additional 50-foot buffer for waterways, including <br />Idaho Creek and the Smith & Emmons Ditch lateral to Lighthouse Cove. The 60-foot <br />offset will be mined at a 3:1 slope along waterways, all other structures will have an <br />unmined 60-ft offset with a mining face nearly vertical to '/~ : 1 slope. Direction of mining <br />will be from the east to the west, and will progress down to the siltstone bedrock. <br />Lafazge will utilize the existing farm access points during mining operations, these gravel <br />roads have been identified in Exhibit C. No additional culverts will be constructed. The <br />access roads are approximately 15 feet wide; no improvements to the roads aze necessary. <br />The access points will be used for initial transportation of the heavy equipment (scrapers, <br />front-end loaders, etc.) to each Phase, removal of same equipment from the site once <br />mining is complete, and for regular employee access. Once mining operations are <br />complete, the roads will be restored to their original condition. The company is not <br />proposing to haul any material from the site. <br />Lafazge West, Inc. does not intend to install an asphalt plant or concrete batch plant on site. <br />Additionally, there will be no hazardous waste used on the site. Sand and grave] are the <br />primary minerals produced. Principal intended use of the mined products is construction <br />aggegates. <br />Mining Schedule <br />Mining is currently projected to occur at the rate of approximately .5 Mtons/year. Based on <br />an estimated reserve of 1.5 million tons, mining will be completed in approximately three <br />years from the start of operations. Mining is currently projected to commence in the winter <br />of 2005. <br />DMG 1l2 Permit <br />Page 8 of 49 <br />
