D-31 <br /> Drying and Screening Plant <br /> The drying and screening plant facilities will occupy an approximately 280 ft. by 350 ft. area within the <br /> central portion of the Plant Area. It will consist of an assemblage of permanently installed equipment,to <br /> include a rotary drying unit and various screening decks, all of which will be placed atop a concrete <br /> foundation. <br /> As depicted in Figure D-3: Process Flow Schematic, the post drain-down intermediate product will be <br /> routed to a drying plant, where it will be passed through gas-fired rotary dryer unit(s), after which all <br /> material will report to a 1/16" scalping screen to remove any foreign material from the product that may <br /> have been introduced during the transfer and/or drying processes. The reject will be stockpiled (minor <br /> quantities)under individual scalping screens,until moved to pit for disposition(as minor backfill). Each <br /> gas fired rotary dryer will have a cyclone and bag house to remove fines material(particulate)from the air <br /> flow stream; this fines "reject' will be conveyed to a small "reject" stockpile, where it will remain until <br /> space constraints dictate their removal to the process waste stockpile. The desired#30/140 end(saleable) <br /> product emanating from the gas-fired rotary dryer and scalping screen circuit will be conveyed to the Dry <br /> Sand Storage Building where tripper conveyors will again be utilized to stockpile the product. <br /> Oversize( eject) Stockpile <br /> The Dry Plant oversize stockpile will be situated proximal to the screening tower,which is to be located at <br /> the west end of the Dry Plant facilities. Oversize material (i.e., that greater than 1/16") from the final <br /> screening process will be stockpiled via a radial stacking conveyor unit. It is anticipated that the oversize <br /> stockpile will, at maximum capacity, encompass an approximately 55-ft. diameter footprint. Oversize <br /> material will be utilized in miscellaneous site grading and/or backfill activities. <br /> Product Storage Silos and Loadout Facilities <br /> Six separate product storage silos will be situated across the loadout road at a location proximal to the <br /> northwest corner of the Plant Area. The product storage silos will directly fill third-party over-the-road <br /> tractor-trailer units via telescopic spout(s)equipped with integrated dust collection capability. <br /> CSC estimates that, at full-scale operations, an average of approximately 11,000 tons per day of saleable <br /> product will be loaded,resulting in an estimated total of 440 round-trip truck-trips per day.
