Massport Approves PPA for the Boston Harbor Dredging Project

The Massachusetts Port Authority (Massport) Board yesterday approved the execution a Project Partnering Agreement (PPA) with the U.S. Army Corps of Engineers and MassDOT to start the Boston Harbor Dredging Project.

A signed agreement allows USACE to bid contracts for construction on a Confined Aquatic Disposal cell (CAD cell), which is needed for the maintenance dredging of the Inner Harbor Main Ship Channel.

Maintenance dredging will restore the inner harbor to 40 feet and is the first phase of the larger dredging project. Without maintenance dredging, the harbor will continue to silt, leading to increased transit times, economic inefficiencies, and navigational safety concerns.

This portion of the harbor was last dredged by the Corps in 1986, and is vital to the maritime economy in Massachusetts.

The maintenance dredging and associated construction on CAD cell by the Army Corps of Engineers will allow for the terminals on the Chelsea Creek and Mystic River, including the Commonwealth energy corridor, to continue to operate in the most efficient manner; providing the region with a multitude of bulk products,” said Lisa Wieland, Massport’s Port Director.

The CAD cell is a key factor in the maintenance dredging of the inner harbor ship channel, which will ensure vessels carrying home heating oil, salt, Logan Airport’s jet fuel, and cars to the Autoport can continue to get to terminals on the Chelsea and Mystic Rivers.

Massport and MassDOT agreed to pay $5 million, while the Corps will spend $12 million from its FY’16 Work Plan for the design and construction. CAD cells have been constructed in Boston Harbor for past dredging projects.

In June 2014, President Obama signed the Water Resources Reform and Development Act (WRRDA) into law and specifically mentioned the Port of Boston in his remarks on water infrastructure and harbor deepening projects across the country.

The $310 million Boston Harbor Dredging Project will deepen the main channel used by container ships from the existing 40 feet up to 51 feet.
