This report documents the findings of a study that examined methods for assessing the risks of unexploded ordnance (UXO) and munitions constituents on former military training land. The report focuses specifically on methods applicable to sites on closed, transferred, and transferring bases that are being or have already been converted to civilian uses. The Army has not yet arrived at a consensus with the Environmental Protection Agency (EPA), state agencies, and other concerned groups about what process should be used to assess risks and evaluate potential responses to sites contaminated with both UXO and munitions constituents. This report is the first to analyze in detail all of the approaches the Army has developed to assess risks of UXO sites. It also recommends how the Army can move forward with developing risk assessment protocols that will be acceptable to all of those involved at UXO sites.
The report should interest anyone involved in the transfer of military sites under the Base Realignment and Closure (BRAG) program and with management of the Formerly Utilized Defense Sites (FUDS). Although the report was written for the Army, it will also be of broad interest to the Department of Defense (DoD), the EPA, the Department of the Interior, state regulators, and citizen groups involved at BRAG and FUDS sites. In addition, aspects of this report should interest Army and DoD policymakers involved in the planning of possible future base closure rounds.
