[ARCHIVED] Back Cove South Storage Facility-Notice of No Significant Impact


            The State of Maine, Department of Environmental Protection, has issued a Finding of No Significant Impact in compliance with the environmental review requirements in Section C of the State of Maine’s Clean Water State Revolving Loan Fund Rules, Chapter 595, on behalf of the City of Portland.

            The proposed CSO abatement project, named Back Cove South Storage Facility Project, primarily entails the construction of a 3.5 million gallon underground concrete storage tank in the Back Cove Park area.  The tank will provide storage for combined sanitary and stormwater flow during wet weather events.  The proposed project also involves the installation of new underground pipe and associated manholes, work in Back Cove to modify the existing outfall area at CSO #18, stabilization along the shoreline, and the construction of an electrical maintenance building.  The purpose of the project is to reduce combined sewer overflow volumes and frequency at three existing CSOs that discharge to Back Cove. 

            A review of the proposed action by the DEP has indicated that it will not result in a significant adverse impact to the environment.  Therefore, a Finding of No Significant Impact has been issued for the project.

            Further records in regard to the project can be found at this website:  Comments relative to this decision may be submitted to the Brad Roland of the City of Portland at  or to Karen Hefler of the State of Maine DEP at   Comments must be received within thirty days of this notice.
