Book Description
The Craney Island disposal area is a 2500-acre confined dredged material disposal site located near Norfolk, Virginia, one of the largest such sites in the Nation. The purpose of constructing such a diked disposal area is twofold: (a) to provide adequate storage capacity for dredged material over the design life of the facility and (b) to provide adequate sedimentation of dredged solids to maintain water quality of effluent.

Book Description
The Craney Island Management Plan was developed to extend the life of the Craney Island Dredged Material Management Area (CIDMMA). The CIDMMA is used to dispose maintenance and new work dredged material from the project area. With current practice, CIDMMA would reach ultimate capacity by the year 2000. If, however, suitable material is barged to the sea and only contaminated material is placed in the facility (Restricted Use Program), then the life of the facility can be extended. Two tasks were addressed in this study: (a) determine service life under Restricted Use and (b) determine contaminant losses and conduct a Comprehensive Analysis of Migration Pathways (CAMP) expected to occur under Restricted Use. The results showed that the service life of the CIDMMA could be extended under Restrictive Use for approximately 140 years under baseline coniditions or 90 years under Worst Case conditions. The CAMP analysis was conducted along three major contaminant migration pathways (effluent, leachate, and volatile). Effluent was the most significant pathway for metal losses and volatilisation and for polynuclear aromatic hydrocarbon (PAH) losses. Leachate losses under a fully dewatered condition would not exceed effluent losses for some metals. PAH losses for a fully dewatered condition would not exceed effluent losses.

Book Description
Three alternatives for using Craney Island Disposal Area (CIDA) during deepening Norfolk Harbor are evaluated. Alternative 1 considers CIDA in its present configuration; Alternative 2 assumes CIDA is subdivided and managed as recommended in the CIDA Management Plan (Palermo, et. al., 1980) throughout the deepening project; Alternative 3 requires the construction of an expansion to contain all or part of the new work and maintenance volume dredged during the deepening project and requires the development of the existing disposal area as suggested in Alternative 2. Recommended: Combination of alternatives 2 and 3. Keyword: Dredged material containment.

Book Description
The Craney Island disposal ara is a 2,500-acre confined dredged material disposal facility located near Norfolk, VA. In 1981, the Craney Island Management Plan (CIMP) was developed to extend the useful life of the site for disposal of maintenance material from the project area. The CIMP called for subdivision of the site into three subcontainments and use of alternating filling and dewatering cycles. Management of the site in general accordance with the CIMP was implemented in 1984. This report documents site operations and monitoring data for the Craney Island disposal area from Oct 1980 to Sept 1987. Field sampling operations, laboratory testing, and monitoring and survey data are described and interpreted. Based on the monitoring data collected to data and projections of future fill rates, the site will be filled to elevation +30 ft during FY 2000 if the present intensity of management is continued. If the site had not been subdivided and management for dewatering not initiated, the site would fill during FY 1997. Therefore, the CIMP as implemented to date will result in a gain in useful life of approximately 3 years or 2% of the remaining capacity. Differences are due to a combination of factors, including inaccuracies of models in projecting long-term fill rates, inefficiencies in implementing the CIMP, natural inefficiencies of desiccation processes, and the placement of significant volumes of new work material in the site.
