Maintenance Dredging and Channel Maintenance at Naval Weapons Station Earle, New Jersey

This is a Maintenance Dredging Project is for Maintenance Dredge the areas surrounding piers at Naval Weapons Station (NWS) Earle including all berths, turning basin, terminal channel, and a portion of Sandy Hook Federal Channel. The project number is #1652592. The dredged material will be tested to determine if it meets criteria for remediation material to be used at the Historic Area Remediation Site (HARS) and for placement at the Sea Bright Offshore Borrow Area (SBOBA). This project will be done in order to re-establish the minimum required harbor depths needed for access by the Naval vessels that use these facilities. The proposed project's maintenance dredging work will remove approximately 2,260,169 cubic yards (CY). The estimated quantities assume two feet of overdredge. The dredging work shall be done using a clamshell dredge. While virtually all of the turning basin and pier area will require dredging the identified channel areas will generally only require dredging where shoaling has reduced the depth. Piers 3A and 4 (both east and West sides, turning basin, terminal channel and the Sandy Hook Federal Channel) shall be dredged to a project depth of 45 feet below mean lower low water (MLLW) plus 2 feet of overdepth. Pier 2 is in Caretaker status and is excluded from the project area. Sediment sampling and testing will be done as part of the permitting process. Results of sediment sampling work will determine if any areas are deemed not suitable for HARS or SBOBA placement. If any areas are deemed not suitable for HARS or SBOBA placement then this material will be quantified and an alternative upland disposal site will be identified along with estimating associated cost. All HARS suitable material shall be dredged via clamshell bucket and transported and disposed at HARS via bottom dumping scow. Non-HARS material, if any, will be transported via barge and/or trucked to an upland disposal site pursuant to location of site and details of disposal requirements TBD.
