D-32 <br /> this,maintenance and service vehicles and material/supply delivery vehicles are anticipated to add another <br /> 10 to 20 round-trip truck-trips per day,on average. Each loaded/scaled truck will be provided with a load <br /> ticket,and once loading is completed,the trucks will continue north and west on the short remainder of the <br /> loadout road in order to re-access Weld County Road 59, thence turning south. It is anticipated that the <br /> main transport route from the site will be south on Weld County Road 59 to Interstate 76, with ultimate <br /> delivery of the industrial sand products to customers located within the regionally proximal area. <br /> Ancillary Facilities <br /> Certain ancillary facilities will be established in order to support the mining and processing operations,to <br /> include the following: <br /> • Plant Offices —the main plant office will consist of two 8-ft. by 20-ft. portable containerized units <br /> aligned alongside the west side of the product storage bin structures. These two units will be utilized <br /> as primary and secondary administrative offices,respectively. Two additional units,also consisting of <br /> two 8-ft.by 20-ft.portable containerized units,will also be located in this area,one of which will serve <br /> as a quality control laboratory/office and the other as an employee breakroom. <br /> Vendor and visitor parking will be established alongside the main plant office(s). Employee parking <br /> will be located immediately to the north of the office structure alignment. <br /> • Water Sup..ply and Storage—Onsite water storage will be provided mainly through a bulk water storage <br /> tank (21,000 gallons capacity) located proximal to the wet plant facilities. In addition, in-process <br /> vessels, to include the clarifier unit(45,000 gallons capacity) and the"clear well' (13,000 gallons of <br /> clarified water)will further augment the water supply circuit. <br /> CSC has estimated the total(in-circuit)water requirements for the Keenesburg No. 2 Mine operations <br /> to be on the order of 9,000,000 gallons. Make-up water requirements for mining and processing <br /> activities are anticipated to be approximately 800,000 gallons per day,inclusive of all requirements for <br /> process water make-up that would be attributed to evaporative loss, dust control applications, <br /> entrainment in fines disposed to the fines recovery pit,etc. <br /> Fugitive dust suppression activities (i.e., the use of water trucks for haul road and related dust <br /> suppression requirements) are anticipated to consume an estimated 32,000 gallons per day.
