Anacostia River Sediment Project: 90-Percent Design Report
DOEE is pleased to announce the release of the Anacostia River Sediment Project (ARSP) 90-Percent Design Report and solicit public comments on December 3, 2024. The purpose of this 90-percent Design Report is to describe the process that has been used to design the selected remedy for clean-up of the eleven early action areas described in the Interim Record of Decision. The 90-percent Design Report includes a description of the various components of the remedy and the design elements that were prepared so far for the detailed design. It builds on the 60-percent Design Report, which enabled stakeholders to review the concepts and design criteria and provide comments and input. This document also summarizes the Pre-Design Investigation Report and Treatability Study, which provided additional data for the Remedial Design that were not available from the Remedial Investigation.
Please go to restoretheanacostiariver.com and proceed to the Remedial Design tab and the 90 Percent Design Report to access the report and appendices. There is a 30-day review period with public comments due by January 2, 2025. The stakeholders asked for the extension of the comment period to allow additional time to provide their review and feedback. Based on their request, DOEE has now extended the comment period with revised closing date of February 3, 2025.
Upcoming Public Meeting
To facilitate better understanding of the 90-Percent Design Report and respond to questions, DOEE will hold a virtual public meeting on December 16, 2024, from 6:30 to 8:00pm.

Beneficial Use Guidance for Dredged Material, July 2024
DOEE released the latest Beneficial Use Guidance for Dredged Material on July 31, 2024, after considering all the agency, public and stakeholder’s comments. The purpose of this guidance document is to provide a framework for the beneficial use of dredged material that protects public health and the environment, complies with District and federal regulations, and outlines the general guidance and risk-based screening criteria for the sampling and testing of dredged material. DOEE recognizes that some dredged material is a valuable resource that can be beneficially (re)used for purposes such as constructing wetlands, building living shorelines, providing flood protection, and supplementing construction fill. DOEE anticipates that most of the dredged material would be focused on placement in an aquatic environment with backup option towards upland placement. The document aligns with USACE’s goal of achieving 70% beneficial reuse and also with the existing beneficial guidance from USACE, MDE and other state agencies to promote and implement projects for beneficial use of dredged material as a resource for reuse.

Anacostia River Sediment Project Overview
The Anacostia River and the land area that drains to the river have a long history of urbanization, industrialization, and agriculture, which has resulted in pollution, poor water quality, and contaminated sediments in the river bed. The District Department of Energy and Environment (DOEE)’s Anacostia River Sediment Project was initiated to identify any potential sediment contamination in the nine-mile tidal portion of the Anacostia River, Washington Channel and Kingman Lake.
Since 2013 the Anacostia River Sediment Project has proceeded through a succession of phases. The initial phases determined the nature and extent of the sediment contamination (Remedial Investigation) and the risk posed to humans and wildlife (Risk Assessment). These studies concluded that elevated concentrations of contaminants, including polychlorinated biphenyls (PCBs), polycyclic aromatic hydrocarbons (PAHs), dioxins, heavy metals, and pesticides from industrial, urban, and human activities are present in sediment throughout the Anacostia River, posing a potential risk to humans or aquatic wildlife.
Next the Anacostia River Sediment Project identified potential solutions to the risks posed by contaminated sediments (Feasibility Study). After input was gathered from broad array of stakeholders on the available options for remediation (Proposed Plan), DOEE issued an Interim Record of Decision that identifies the early action cleanup remedies for the most contaminated areas in the river and outlines the process for their implementation.
Interim Record of Decision:
On September 30, 2020, the Anacostia River Sediment Project released an Interim Record of Decision (ROD) outlining the findings of existing Anacostia River contamination and early actions that the District will be taking to cleanup the contamination.
The Interim ROD focuses on remediating PCB-contaminated sediments. In most of the river, higher levels of contaminants are found in its deeper sediments, suggesting river pollution came from historic industrial activities that occurred decades ago. In some regions of the river, higher levels of contaminants are found close to the surface of the river bottom suggesting recent and/or on-going activities have led to contamination. In both scenarios, removing or containing the most contaminated sediment can substantially reduce risk to human health and wildlife.
The Interim ROD establishes specific numerical cleanup goals and identifies 11 Early Action Area “hot spots” in the Anacostia River, Washington Channel, and Kingman Lake where PCB contamination is highest. Overall, an area of approximately 77 acres will be cleaned up at an estimated cost of $35.5 million, reducing the human health risk from PCBs.

Administrative Record File
The administrative record file provides public access to Anacostia River Sediment Project documents. This includes records that the Department uses or considers for project decisions, as well as documents that demonstrate the public’s participation in the project.
To utilize the administrative record file, please open the index file within the link below, which provides a list of all documents and their respective locations within folders and subfolders.
Community Involvement Plan
For the public, stakeholders, and parties potentially responsible for pollution, DOEE has also prepared a Community Involvement Plan (CIP) for the Anacostia River Sediment Project that serves as a planning tool to promote an open dialogue throughout the Department’s investigation and during any remedial cleanup. DOEE is fully committed to involving the public in every phase of the investigation and cleanup efforts in a substantial and significant manner to meet established goals.
