WATERWAY AND LOCATION:  The proposed project is located within the Anacostia River, the Washington Channel, and Kingman LakeThe project/review area includes within the Anacostia and Kingman Lake from W side of Anacostia Ave NE, 1,300 feet N of the intersection of Benning Road and Anacostia Ave NE; at Latitude N 38.900666 and Longitude W -76.95968; in Washington, DC.

EXISTING CONDITIONS:  The Anacostia River Sediment Project includes approximately nine (9) miles of the tidal portion of the Anacostia River that begins at the confluence of the Northwest Branch and Northeast Branch near Bladensburg in Prince George’s County, Maryland and extends downstream to its confluence with the Potomac River (Figure 1.1).  The study area is divided into three (3) Operable Units (OUs):  Main Stem OU (Anacostia River main channel), Washington Channel OU, and Kingman Lake OU.  Four constituents of concern have been identified in the sediment in the Anacostia River Sediment Project that pose risk to human health or ecological receptors.  The constituents of concerns include total polychlorinated biphenyl (PCB) congeners, dioxin toxic equivalent (TEQ), chlordane, and dioxin-like PCB TEQ.

PROJECT PURPOSE:

Basic:  Sediment remediation in the Anacostia River in Washington, DC.

Overall:  To reduce the risk to human health and the environment associated with contamination within the tidal Anacostia River and associated water bodies as well as enhancement and maintenance of existing channels within Kingman Lake to protect remedy areas and improve water quality in the system.

PROPOSED WORK:  The applicant requests authorization to perform subaqueous amended capping, in-situ treatment, dredging, and outfall armoring in Early Action Areas (EAAs) within three sections of the Anacostia River:  Kingman Lake, the Anacostia River Main Stem, and the Washington Channel.  Approximately 42.7 and 10.5 acres would be covered by amended capping and in-situ treatment, respectively, including 11.1 ac of impacts to SAV and 7.3 ac of impacts to tidal wetlands.  Approximately 35,000 cubic yards of sediment would be dredged and approximately 68,000 cubic yards of material would be placed for capping.  Table 1 provides dredge and fill quantity by EAA.

AVOIDANCE AND MINIMIZATION:  The applicant has provided the following information in support of efforts to avoid and/or minimize impacts to the aquatic environment:  The Focused Feasibility Study Report (Tetra Tech 2019) details the initial development and screening of alternative for addressing contamination sediments within the Anacostia River study area.  Each alternative was evaluated based on effectiveness, technical ability to implement, and cost.  The proposed design minimizes impacts to mapped submerged aquatic vegetation (SAV) and tidal freshwater wetlands by using in-situ treatment rather than dredging/capping within the largest wetland area in Kingman Lake.

COMPENSATORY MITIGATION:  The applicant offered the following compensatory mitigation plan to offset unavoidable functional loss to the aquatic environment:  The applicant would mitigate for the permanent loss of wetlands and/or SAV through the restoration/creation/enhancement of aquatic habitat within Kingman Lake including SAV planting, emergent marsh creation, invasive species management, and enhancement of mudflat habitat.

CULTURAL RESOURCES:  The Corps is evaluating the undertaking for effects to historic properties as required under Section 106 of the National Historic Preservation Act.  This public notice serves to inform the public of the proposed undertaking and invites comments including those from local, state, and federal government Agencies with respect to historic resources.  Our final determination relative to historic resource impacts may be subject to additional coordination with the State Historic Preservation Officer, federally recognized tribes and other interested parties.

The District Engineer’s final eligibility and effect determination will be based upon coordination with the State Historic Preservation Office and/or Trible Historic Preservation Office, as appropriate and required, and with full consideration given to the proposed undertaking’s potential direct and indirect effects on historic properties within the Corps-identified permit area.

ENDANGERED SPECIES:  The Corps has performed an initial review of the application, the United States Fish and Wildlife Service Information for Planning and Consultation (IPaC), National Oceanic Atmospheric Administration Service Fisheries Greater Atlantic Region Section 7 Mapper, and the National Marine Fisheries Service Critical Habitat Mapper to determine if any threatened, endangered, proposed, or candidate species, as well as the proposed and final designated critical habitat may occur within the boundary of the proposed project.  Based on this initial review, the Corps has made a preliminary determination that the proposed project may affect species and critical habitat listed in Table 2.  No other Endangered Species Act (ESA)-listed species or critical habitat will be affected by the proposed action.
