Jay M. Cashman of Quincy Shipyard, LLC is seeking a permit from the U.S. Army Corps of Engineers, New England District, to impact waters of the U.S. in conjunction with dredging in the Fore River in Quincy, Mass.
The proposed work involves dredging a 150-foot by 50-foot area to a depth of approximately 38 feet below the horizontal plane of mean low water.
An estimated quantity of 23,000 cubic yards of silt will be removed by mechanical means and disposed of at the Massachusetts Bay Disposal Site. The dredge area is located adjacent to Pier 1 at the Quincy Shipyard, located at 549 South Street in Quincy.
The dredging is proposed to accommodate larger vessels with deeper drafts and to match the recent adjacent dredging of the Fore River to an elevation of 38 feet below mean low water.
The dredging portion of the proposed project will impact approximately 7,500 square feet of Essential Fish Habitat (EFH) for various species and life stages. Habitat at this site can be described as subtidal silt.
Loss of this habitat may adversely affect these species.
The Corps has made a preliminary determination that the site-specific adverse effect will not be substantial. Further consultation with the National Marine Fisheries Service regarding EFH conservation recommendations is being conducted and will be concluded prior to the final permit decision.
