Raw blasted basalt material will be loaded into a portable crusher/screen plant where various <br /> sizes of product will be created and sorted into separate size-dependent stockpiles. Maximum <br /> processing capacity is approximately 5,000 tons per day. The crushing operation, asphalt hot <br /> plant, concrete batch plant, and processed stockpile locations may change during the mine's life <br /> as mining proceeds across the mining area. <br /> Normal groundwater levels are known to be greater than 100 feet below the pre-mined ground <br /> surface based on well data in the surrounding area. Well data is further detailed in Appendix 3 of <br /> this application. No water will be encountered in the operation. However, in the unlikely event <br /> that water is encountered during mining, excavation will immediately stop and the area will be <br /> backfilled with at least 2 feet of overburden to cover any exposed water.No pit dewatering will <br /> take place as the groundwater table is below the bottom of the pit elevation shown on Maps C-1 <br /> and C-2. <br /> Mining activities are expected to occur all months of the year and processing operations that <br /> include screening and crushing of gravel will occur concurrently. Mining of the deposit will <br /> occur to the limits shown on Map C-2. Expected annual average production is 1,000,000 tons. <br /> Actual production rates will fluctuate based on market conditions. Raw material will be <br /> processed and sold as various products: crushed rock, chips, and road base. "Naturals" or sandy <br /> fines from the screening operation are expected to make up approximately 10%of the raw <br /> material mined and will be mixed into overburden. <br /> Used asphalt pavement and concrete rubble may be imported and stockpiled on site to be used <br /> for future crushing and stockpiling for use as a recycled material in new construction. <br /> Additionally, imported concrete and asphalt may be used in the base layers of backfilling and <br /> will be thoroughly covered with overburden and topsoil as per the reclamation plan. This <br /> material will be certified per Rule 3.1.5(9) as detailed in Exhibit E. Import and use of recycled <br /> asphalt and concrete on site is not anticipated but the right to do so is requested in this filing. <br /> Occasionally, soil that is determined to be free of debris and is certified inert may be brought to <br /> the site and stockpiled for use during reclamation. <br /> Topsoil, overburden, and blasted shale from newly disturbed areas will be used to reclaim mined <br /> out areas; therefore, total site disturbance will be minimized as reclamation will occur <br /> Bradford Mesa Quarry <br /> January 2020 D-9 <br />
