Abstract : Maintenance dredging is proposed in the Mystic and Chelsea Rivers and in President Roads Anchorage. Impacts during dredging and disposal operations would include a temporary increase in turbidity and a minor release of certain contaminants. These impacts would not significantly affect the water quality or organisms in the vicinity of the activities. The operation would involve displacement of the harbor sediments which would remove bottom-associated invertebrates from the dredge sites and bury those associated with the disposal site. Recolonization would occur in the project area soon after operations ceased. Bioassay tests indicated that disposal of the sediments would not cause any acute chemical impacts to organisms in the vicinity of the dump site.
