Management Plan for the Disposal of Contaminated Material in the Craney Island Dredged Material Management Area

Abstract

"At the request of the U.S. Army Engineer District, Norfolk, the U.S. Army Engineer Waterways Experiment Station (WES) developed the Craney Island Management Plan (CIMP) to extend the useful life of the Craney Island Dredged Material Management Area (CIDMMA). The CIDMMA is used for disposal of maintenance and new work dredged material from the project area. The initial goals of the CIMP included maximization of storage capacity by dewatering and densification of the confined dredged material and maintenance of an acceptable effluent water quality. Since that time, the management approach as recommended in the CIMP has been generally implemented. With current practices, the CIDMMA is expected to reach its ultimate capacity around the year 2000. The useful life of the CIDMMA may, however, be extended if suitable material is barged to sea and unsuitable (i.e., contaminated) material is placed in the facility; thus, the Restricted Use Program was formulated. The Norfolk District has, therefore, requested that WES investigate the feasibility of the proposed Restricted Use Program for extending the useful life of the CIDMMA."
