~;: <br />SECTION 1: DESCRIPTION OF INDUSTRIAL ACTIVITIES <br />The activities checked below are activities that are presently performed on-site or are <br />expected to be present in the suture. <br />STRIPPING <br />The overburden is removea and the matenai is either sold, hauled away or stoc:<piled. <br />Stockpiles may be in the form of berms. <br />`EXCAVATION -WET MINING ENVIRONMENT <br />(Check onel <br />~Dragline: <br />Sane and gravel is excavated belov~ water levei and winrewea adjacent to the open <br />avatar for the purpcse of de~roatering. <br />Auer sufficient de~Natering has occurred, the pit run material can be Conveyed or <br />hauled by means or loader or trucks for final wasning and screening. <br />CDredging -bucket type: <br />Material is excavated `rpm below water level and directly conveyed to the plant for <br />final washing and screening. <br />CDredging • pump type: <br />Material is sucked into an underwater pipeline and pumped to the surface. A booster <br />pump is so~;~eti~„es Headed to pump the material through the pipeline to the first <br />processing screen which is sometimes as high as 60' from the ground. <br />EXCAVATION -DRY MINING ENVIRONMENT <br />(Check one) <br />^An alluvial depostt which intercepts ground water which is pumped down <br />CA dry terrace deposit wherein ground water is not encountered. <br />When necessary, the water table in the mining area is lowered by means of <br />dewatering ditches and pumps. fvlaterial can be excavated ~rvithin the perimeter ditch <br />without encountering ground water. Moist to dry sand and gravel can then be <br />conveyed by means of loader, truck or conveyor belt to stockpiles or processing plant. <br />
