Normal groundwater levels are known to be greater than 100 feet below the current pit floor. No <br /> water will be encountered in the operation. However, in the unlikely event that water is <br /> encountered during mining, excavation will immediately stop and the area will be backfilled with <br /> at least 2 feet of overburden to cover any exposed water.No pit dewatering will take place as the <br /> groundwater table is below the bottom of the pit elevation shown on Maps C-1 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, road base, concrete, and asphalt. <br /> "Naturals" or sandy fines from the screening operation will be mixed into overburden and are <br /> expected to make up approximately 10%of the raw material mined. <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. Import and <br /> use of recycled asphalt and concrete on site is not anticipated but the right to do so is requested <br /> in this filing. Occasionally soil that is determined to be free of debris and is certified inert may be <br /> brought to 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 /> concurrently with mining. This will reduce material moving as well as reduce the maximum area <br /> to be reclaimed; maximum disturbance is discussed in Exhibit L. <br /> Excess shale and surplus overburden will be permanently stored in a dump located east of the <br /> processing area designed with 3HA V slopes, see Maps C-2 and F-1. This dump will be utilized <br /> as excessive waste fines, overburden, and/or shale are encountered during mining. The dump <br /> will only be utilized if the waste material cannot immediately be placed into a mined-out phase. <br /> The dump will be constructed by edge dumping in lifts of approximately 25 feet in height <br /> creating an overall final slope of 3H:IV. A settling pond will be located at the base of the dump <br /> Bradford Mesa Quarry <br /> August 2019 D-7 <br />
