Dredged Material Management Plan (DMMP) – Port of New York & New Jersey

New York District (NYD) is responsible for maintaining the Federal navigation channels within the Port of New York and New Jersey. Maintenance of these channels via periodic dredging to authorized dimensions is critical to safeguarding commercial and recreational navigation within the port. NYD is committed to environmentally and economically sound management of maintenance dredging material as defined by applicable laws, regulations, and policies.

A Dredged Material Management Plan (DMMP) is a long-term strategic plan for the placement of material to be dredged from Federal, State and local [new and existing] channels. A DMMP ensures that there is adequate placement capacity to properly manage dredged material in an environmentally and economically acceptable manner. The DMMP Implementation Report (IR) for the Port of New York and New Jersey was published in 1999. Several updates have since been made to this DMMP, with the most recent update issued in 2008. In 2022, the NYD was allocated funding to develop a subsequent Interim DMMP Update.

Interim DMMP Update (2025-2029) – Port of New York & New Jersey

Given the prevailing uncertainty in the remaining capacity of the Historic Area Remediation Site (HARS) and the anticipated construction of the Harbor Deepening Channel Improvements (HDCI) project (an ongoing, separate effort), the NYD is developing an Interim DMMP Update to ensure adequate near-term placement capacity exists for current and anticipated near-term dredged material placement needs (2025-2029). A separate DMMP is expected to be prepared for the HDCI project prior to construction.  In addition to evaluating the near-term placement capacity, this Interim DMMP Update will re-evaluate the Federal Standard (modified pursuant to Section 125 of WRDA 2020; 33 U.S.C. § 2326g) and identify additional beneficial use opportunities for dredged material.

Status – As of March 27, 2024

A Project Management Plan (PMP) has been developed to outline the milestones and work tasks of the Interim DMMP Update for the Project Delivery Team (PDT). This document is subject to change as the PDT progresses with the Interim DMMP Update.

Coordination with state and local agencies is ongoing. The PDT is working closely with the New York and New Jersey Harbor Regional Dredging Team (NY-NJ Harbor RDT) to gather input from members. Engagement with primary stakeholders initiated in March 2024.

Public outreach has been initiated as of January 31, 2024. The schedule for public information sessions will be posted on this webpage when available.

Public Information Sessions

Public Information Sessions for the Interim DMMP Update are expected between May-September 2024.  


We would like to solicit feedback on the Interim DMMP Update from interested entities on future placement needs/ opportunities and public engagement. 

Please submit a feedback form with your comments by May 17, 2024.
