On behalf of the New Jersey Department of Transportation Office of Maritime Resources (NJDOT OMR) the Center for Advanced Infrastructure and Transportation (CAIT) at Rutgers University performed Quality Assurance (QA) inspections for placement of PDM at the Site. The QA inspections provided information to the agencies on whether or not the utilization of PDM as construction fill at the upland sites is practical. NJDEP approved the beneficial use of processed dredged material (PDM) as a grading and barrier layer fill. Approximately 1.2 million cubic yards of PDM was placed at the Site from October 2004 to September 2006. Dredged sediments from New York/New Jersey Harbor were mixed with Portland cement (8% on wet weight basis) in processing facilities at Port Newark and Jersey City. Processed PDM was allowed to cure for 48 hours at the processing facilities and then transported to the Site for beneficial use. A summary of PDM placement activities over a two year period is provided in this Report. Recommendations are provided on potential improvements with respect to PDA handling and field placement operations.
