Naval Research Laboratory, Chesapeake Bay Detachment

Environmental Restoration Program Public Website


UXO-001 Hypervelocity Low-Pressure Gun Site

The Department of the Navy (Navy), with concurrence from the Maryland Department of the Environment (MDE), recently completed a Focused Feasibility Study (FFS) to evaluate alternatives for a response action at the Unexploded Ordnance-001 (UXO-001) Hypervelocity Low-Pressure Gun (HVG) site at Naval Research Laboratory (NRL) Chesapeake Bay Detachment (CBD) in Chesapeake Beach, Maryland.

The Navy has prepared a Proposed Remedial Action Plan (PRAP) to summarize the environmental investigation activities performed at UXO-001 to date and to provide a rationale for the preferred remedial (treatment) alternative for surface soil at the site. The PRAP was prepared in accordance with Comprehensive Environmental Response Compensation and Liability Act (CERCLA) and the National Contingency Plan.

The NRL-CBD facility encompasses more than 161 acres and includes UXO-001, the site of the former HVG, located near the western property boundary of NRL-CBD and comprises approximately 2.7 acres. The HVG was used between 1967 and 1995 to study the impact of high-velocity projectiles on various target materials. UXO-001 was designated an environmental site by the Navy in 2016 to address lead-impacted soil.

The FFS presents the evaluation of alternatives to remove lead-contaminated surface soil at UXO-001. As a result of the FFS, the Navy is proposing to excavate the lead-contaminated soil and transport it to an approved disposal facility. The excavated areas will be backfilled with clean fill to existing grade.

PUBLIC REVIEW AND COMMENT: Public participation is an important part of the remedy selection process and the Navy’s preferred alternative may be modified based on new information and/or public comments. The Navy will finalize its plan, with MDE concurrence, after reviewing all comments received during the public comment period (June 7-July 6, 2024).

You can review the PRAP and the FFS in the links below:

  • The Proposed Remedial Action Plan is available for review here.

Based on sufficient public interest, a public meeting may be held during which the Navy and MDE will provide more information about the site and describe the alternatives evaluation process for UXO-001. Public comments on the PRAP, including the commenters’ names and addresses, will become a part of the Site Administrative Record, and the Navy will provide a response to comments. The final remedy for the UXO-001 HVG site will be selected only after the public comment period has ended and comments have been addressed.

The NRL-CBD Restoration Advisory Board (RAB) is a vital link between the community and government decision-makers. The Navy and the appropriate regulatory agencies are responsible for making decisions about the Environmental Restoration (ER) Program. Part of the decision-making process is to consider comments from the public and respond to them.

The purpose of a RAB is to encourage regular, two-way communication between the Navy and the local community by:

  Informing the public regarding the progress of planned and ongoing restoration actions at the facility
  Communicating the results of investigations and risk assessments when available
  Receiving feedback from the public as to their specific concerns and information needs
•  Providing the public with the opportunity to comment on and participate in addressing technical decisions associated with ER sites at the facility

The RAB contains representatives from the Navy, Maryland Department of the Environment (MDE), local government officials, and community members. The NRL-CBD RAB was formed in December 2019. The RAB is co-chaired by an elected community member and a Navy representative. RAB members are considered a key source in efforts to communicate openly and effectively with the community at large. They are provided with information about the ER Program and their input on remediation decisions is actively sought.

The Community Involvement Plan describes the Navy’s community involvement program for environmental restoration.
