• Mechanics of Loading, Hauling, and Disposal of CKD. • Currently CKD is disposed of in the following manner: C~ 1. CKD from the plant process is stored in a silo located on the south side of the plant (see attached plan map). 2. A truck, with a totally enclosed bed, is loaded from the silo and the CKD is h:luled to the designated CKD disposal area, located North of the plan[, where the CKD is disposed of. 3. During the week the CKD dump is advanced across the width of the mined out quarry bed. The CKD will have an average thickness of l5 feet. 4. Once a week, 500 tons of waste material (from the active quarry) is hauled to the site and the CKD is covered at the disposal point. 5. The sequence continues in this fashion until the layer from one end of the designated azea has been completed, then a second layer is initiated. This procedure will continue until the area has reached capacity and is ready for final reclamation. • Future Disposal of CKD by Area (including volumes and time schedule) The sequence of disposal areas is as follows: AREA STATUS PER10D VOLU1viE A2 Current CKD disposal site. 10/98 through 220,000 I /2002 A2-A Area has 22,000,000 gallons of water.
