The procedure is briefly outlined below: (1) Following the fine survey (normally a 25 meter grid) the area to have soil removed is recommended by DOE/ERSP. This area is marked on the ground by USAE Survey Team. (2) Vegetation in the area is removed and stockpiled by using a 2% CY scoop loader with a 4 in 1 bucket to limit the amount of soil removed with the vegetation. The vegetation is allowed to dry and then burned. (3) The soil is removed in 6" to 8" lifts by using a dozer to move soil to (4) Scoop loader loads soil on dump truck, (5S) The dump trucks move to beach area stockpile site. stockpile at the edge of area. (6) The dump trucks load on boats for over water transport, stockpile soil at beach area stockpile or dump load in bulk haul boats. jee \ J rom bp Le ut a! ~3 5 i . N f ; . , ; . - s .
