C-2 <br /> Sand will be mined from an open-cut pit by hydraulic excavator and/or front-end loader,loading to articulated haul <br /> truck(s), for subsequent transport to a run-of-mine (ROM) stockpile. ROM stockpile material will then be <br /> introduced to the "wet plant", which will utilize mechanical separation processes (fresh water wash) to produce a <br /> #20/#140 (i.e., less than 20 mesh but greater than 140 mesh) nterim product. Oversize material (i.e., that greater <br /> than 20 mesh) will be scalped off prior to the wash process and routed to an oversize reject stockpile. Undersize <br /> material or"reject"(that less than 140 mesh)will be generated during the wash process(which will employ cyclones <br /> and attrition cells)and the fines reject will be slurried to a dedicated fines recovery pit. The resultant#20/#140 size <br /> fraction(i.e., less than 20 mesh but greater than 140 mesh) interim product will be temporarily stockpiled to allow <br /> for drain down(decant). Wet plant process and stockpile decant waters will be recovered to the extent practicable, <br /> and routed through a clarifier unit in order to maximize process water recycle. <br /> Material from the decant stockpile will be loaded via front-end loader to a feed hopper and a gas-fired rotary kiln <br /> dryer unit for drying,with the dried material then introduced to a dry screening plant. There,the dried material will <br /> be further separated by size fraction(screening), with the oversize (i.e., that greater than 40 mesh)reporting to the <br /> oversize stockpile, thereby facilitating the production of a singular #40/#140 end product (i.e., less than 40 mesh <br /> but greater than 140 mesh). <br /> The #40/#140 end-product will be delivered to and evenly distributed (via telescoping conveyor) within a set of <br /> twin storage bins (i.e., the "east" and "west"bins, respectively), from which the material will be drawn (by front- <br /> end loader) and loaded to a feed hopper for belt conveyor loading of(third-party) over-the-road (OTR) tractor- <br /> trailer units(positioned on a scale)which will enter the Permit Area via the existing ranch service road and exit that <br /> road onto the Permit Area's north-side loadout loop road. The OTR trucks will traverse the loop road in clockwise <br /> fashion, continuing on to the loadout/scaling area. <br /> Each loaded/scaled truck will be provided with a load ticket,and once loading is completed,the trucks will continue <br /> west on the short remainder of the loop road(which will be established along the perimeter of the Permit Area) in <br /> order to re-access the existing ranch service road for return to Weld County Road 59. <br /> It is anticipated that the main transport route from the Keenesburg Project will be south on Weld County Road 59 <br /> to Interstate 76, with ultimate delivery of the industrial sand products to customers located within the regionally <br /> proximal area. <br /> Keenesburg Project—Limited Impact 110 Application_May 24,2019 <br />
