Abstract:

Green Harbor is a small tidal estuary on the west side of Massachusetts Bay, approximately 35 miles by highway southeast of Boston, Massachusetts. It is located within the town of Marshfield in Plymouth County and situated at the mouth of the Green Harbor River, a small stream draining marshlands to the northwest. Upon evaluating the information presented in this Environmental Assessment Report it is concluded that hydraulic emergency maintenance dredging of the portions of Green Harbor Channel indicated is in the best public interest. Hydraulic pipeline dredging is the best operationally suitable method because of the volume of material to be dredged and that this material will be placed on land. Except for small temporary water quality effects, it has been determined that adverse environmental impacts will be minimal. Two major points lead to this determination dredged material is primarily clean sand, thus eliminating a potential source of toxic material, organics, etc., into the water. Furthermore, dredged material is also particularly suitable for beach disposal as it matches closely existing sand.
