If processing of mined materials is to be conducted at, or <br /> adjacent to, the site, describe briefly the nature of the <br /> processing and explain disposal method of tailings or waste <br /> from processing: <br /> Processing: <br /> Near-surface rock and sand deposits are excavated and <br /> delivered by haul truck, bottom loading scrapers, or conveyor <br /> to the Process Plant Site centrally located on the property. <br /> Mining from the existing permitted northerly half of the site <br /> has resulted in the removal of the rolling hilltops. Mining <br /> from the southern portion of the site is anticipated to take <br /> place as an open pit/hilltop excavation operation. Maximum <br /> anticipated pit depths will not exceed 40 feet in the <br /> southwesterly portion of the pit, and 20 feet in the <br /> southeasterly portion of the pit. Pit dimensions are <br /> illustrated in the Excavation/Reclamation Site Plan. <br /> The excavated raw materials are processed by washing, <br /> crushing, rolling, conveying and screening. This process <br /> classifies the raw materials into fill sand, clean sand, and <br /> rock aggregate products, which are sold for construction <br /> purposes, such as road base, shoulder aggregates, decorative <br /> rock, and concrete-related products. Up to 5% of the raw feed <br /> to the plant is wasted as fines. <br /> Please refer to Appendix I for Process Flow Diagrams, and a <br /> summary of the equipment and processing methods. <br /> Processed material is stockpiled on-site in the form of rock <br /> aggregate and sand. Once sold, the final product is then <br /> transported off-site by haul truck. <br /> Waste materials produced from the processing operation are <br /> limited to the clays and fine silts suspended in the process <br /> water. Process water is recycled back through a series of <br /> three recycling/settling ponds, where the clays and fine silts <br /> settle out. The recycled water is then used again. <br /> 7 <br /> CONDOR <br />
