Project Name: Howland Hook Marine Terminal Maintenance Dredging
Location: Staten Island, New York
Project Sponsor: Port Authority of NY & NJ
Completion Date: January 2001
Estimated Value: $4,500,000

Project Scope
CEDT contracted with the Port Authority of New York & New Jersey to conduct this maintenance dredging and beneficial use project. The $4.5 million dollar contract provided for maintenance dredging and upland recycling/beneficial use of up to 70,000 cubic yards of sediments from the referenced terminal berthing areas and the adjacent No Man’s Land area. CEDT subcontracted dredging services to an outside subcontractor. The dredged sediments were transported to CEDT’s portside Claremont DMRF facility located in Jersey City, New Jersey, on the Claremont Channel waterway. Upon receipt at the DMRF facility, the dredged sediments were physically dewatered, off-loaded, screened to remove oversize debris, preamended (solidified), and loaded into railcars for transport to CEDT’s Bark Camp Abandoned Mine Reclamation Facility in Pennsylvania. When received at Bark Camp, the pre-amended materials were off-loaded and transported via off-road trucks to CEDT’s staging & processing area at the mine facility. Additional amending reagents were then added to the preamended material to create a pozzolanic manufactured fill material. The stabilized material was then used to reclaim designated segments of the mine high-wall. Due to a change in site conditions, approximately 45,000 cubic yards of sediment from the Howland Hook Marine Terminal were utilized as part of the full-scale Demonstration Project at Bark Camp for reclaiming and capping mine lands utilizing stabilized dredged sediments.
