Fort Darling Engineering Evaluation/Cost Analysis Addendum

News Release Date:
November 1, 2024

PUBLIC NOTICE OF AVAILABILITY THE NATIONAL PARK SERVICE ANNOUNCES THE AVAILABILITY OF THE ENGINEERING EVALUATION/COST ANALYSIS (EE/CA) ADDENDUM and UPDATED ADMINISTRATIVE RECORD for THE FORT DARLING LANDFILL SITE RICHMOND NATIONAL BATTLEFIELD PARK, VIRGINIA

The National Park Service (NPS) announces the availability for public review of documents comprising the updated Administrative Record File, now including the Engineering Evaluation/Cost Analysis (EE/CA) Report Addendum, for the selection of a removal action at the Fort Darling Landfill Site, located in Richmond National Battlefield Park, Virginia.

The EE/CA Addendum was prepared under NPS authority derived from Section 104 of the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and is consistent with the National Oil and Hazardous Substances Pollution Contingency Plan (NCP). After issuing an initial EE/CA Report in 2016, NPS determined previous assumptions regarding the stability of the steep slope at the northern boundary of the landfill were no longer valid, and an EE/CA Addendum is necessary to address data gaps regarding the extent to which hazardous substances may be released from the landfill north slope and whether exposure to such releases may pose unacceptable risks to human or ecological receptors. The purposes of the EE/CA Addendum are to evaluate the nature and extent of contamination at the Site, describe the removal action objectives (RAOs), describe and evaluate alternatives for addressing risks posed by unconsolidated landfill waste and subsurface soil containing hazardous substances on the landfill north slope, and identify the recommended removal action. The EE/CA Addendum identifies and evaluates four removal action alternatives for the landfill north slope area of the Site ranging from no action to complete removal of landfill waste and contaminated soil. The recommended alternative includes modifying the steep north slope to a more stable angle (33%), covering the exposed waste with two feet of clean soil fill and reestablishment of the native forest. A final response action selection will be made after the public comment period, considering any comments that are received.

The National Park Service welcomes written comments from the public on the proposed removal action and on the Administrative Record File. The public comment period is open from November 1, 2024, through November 30, 2024.
