Marine Corps Base Quantico

The United States Department of the Navy announces the availability of the Record of Decision (ROD) for Site UXO 019 (Grenade Field) located on the Mainside of Marine Corps Installations National Capital Region - Marine Corps Base Quantico (MCBQ). The ROD documents the Navy’s selected remedy for addressing potential contamination from past use and/or disposal of munitions at the site. The selected remedy is limited surface removal of munitions and explosives of concern (which was completed in 2021) and implementation of land use controls.

Using a metal detector, potential munitions items were removed from recreational trails and a 2.3-acre contractor staging area within the UXO 019 area in 2021 under a Time-Critical Removal Action (TCRA). One munitions item (an MK1A1 practice hand grenade), which was ultimately determined not to pose an explosive hazard, was recovered as part of the 2021 TCRA.

Land use controls will include installing warning signs, conducting training, conducting annual site inspections, requiring Excavation Permit Requests for any potential excavation activities, and restricting potential future land uses. The effectiveness of this remedy will be reviewed every five years.

Prior to selecting the remedy defined in the ROD, a Proposed Remedial Action Plan describing the different remedial alternatives considered and the proposed remedy was made publicly available, and a public meeting and comment period were held. No comments or questions on the plan were submitted. The ROD has been reviewed and approved by the United States Environmental Protection Agency and the Virginia Department of Environmental Quality.
