Dredged Material Management Plan Overview

The U.S. Army Corps of Engineers (Corps), Baltimore District, has completed its Dredged Material Management Plan (DMMP), which is a planning document that identifies the quantity of material to be dredged from the Federal, state, and local channels and how the dredged material can be managed in an economically and environmentally acceptable manner. 

The study area for the DMMP effort encompassed Baltimore Harbor, Baltimore Harbor Approach Channels, and the Chesapeake Bay Approach Channels, which extend from the mouth of the Bay in Virginia to the southern approach channels to the Chesapeake and Delaware Canal up to the Sassafrass River, in the upper Bay, Maryland/Delaware. The purpose of the plan is to develop a long-term strategy for providing viable placement alternatives that meet the dredging needs of the Port of Baltimore Federal channels and include consideration of state and local dredging needs.

Priority is given to beneficial uses of the material. The DMMP identifies, evaluates, screens, prioritizes, and ultimately optimizes placement alternatives resulting in the recommendation of a plan for the placement of dredged materials for at least the next 20 years.

The U.S. Army Corps of Engineers, Baltimore District (USACE), and the Maryland Department of Transportation Port Administration (non-federal sponsor) have finalized an Environmental Assessment (EA) and Finding of No Significant Impact (FONSI), in accordance with the National Environmental Policy Act of 1969, for the proposed extension of the existing Wolf Trap Alternate Open Water Placement Site (WTAPS) to the north, increasing the size by approximately 3,900 acres. The WTAPS Northern Extension would be located in the lower Chesapeake Bay between the Piankatank River and Mobjack Bay, approximately five miles east of Mathews County, Virginia. 

The purpose of the work is to provide a cost-effective, environmentally-acceptable placement site for dredged material in response to a recommendation by agencies of the Commonwealth of Virginia, to minimize adverse impacts to overwintering female blue crabs.
