Normal water levels are known to be 3-4 feet below the current pit floor. No water will be <br /> encountered in the operation. However, if water is encountered during mining, excavation will <br /> immediately stop and the area will be backfilled with at least 2 feet of overburden to cover the <br /> exposed water. <br /> Mining activities are expected to occur approximately 2 to 3 months per year, while the <br /> processing operations including screening/crushing can occur any time of the year, however <br /> typically during the months of August through November. The mining of the deposit will occur <br /> to the limits shown on Map C-2 and will be mined to a 1H:1 V slope to near vertical slope in <br /> order to maximize gravel recovery. Backfilling with overburden will create shallower 3H:1 V <br /> reclaimed slopes shown on Map F-1. Topsoil will be applied to overburden slopes at a depth of <br /> 8-12 inches and seeded with rangeland grasses or with meadow mountain seed mix with like <br /> species of brushes such as sage or oak. <br /> The expected annual average production is 60,000 tons. Actual production rates will fluctuate <br /> based on market conditions. The raw material will be sold as various products: crushed rock, <br /> chips, road base, concrete, and asphalt. "Naturals"or sandy fines from any washing operation <br /> wi I be mixed into overburden and are expected to make up approximately 10%of the raw <br /> material mined. A breakdown of the anticipated product tonnages and mined tonnages and a <br /> breakdown of the estimated areas is discussed below. <br /> Used asphalt pavement and concrete rubble is also stockpiled on site to be used for future <br /> crushing and stockpiling for use as a recycled material in new construction. Occasionally, soil <br /> that is determined to be free of debris and is inert is brought to the site and stockpiled for use <br /> during reclamation. <br /> Mine access will be via County Road 62A accessed from County Roads 62 and 129, as it has <br /> been to this point. <br /> No pit dewatering will take place, as the groundwater table is below the bottom of the pit <br /> elevation shown on Map C-2.No groundwater will be exposed, and if it is encountered, pits will <br /> be backfilled to two feet above groundwater. <br /> Fetcher Vale Pit <br /> Mav 2018 D-2 <br />
