Summary: Because of concerns about the long-term budgetary implications associated with the environmental cleanup of the Department of Defense (DOD) training ranges, GAO examined (1) the potential magnitude of the cost to clean up these ranges in compliance with applicable laws and regulations, (2) the scope and reliability of DOD's training range inventory, and (3) the methodologies used to develop cost estimates. GAO found that DOD lacks complete and accurate data with which to estimate training range cleanup costs. DOD has not done a complete inventory of its ranges to fully identify the types and extent of unexploded ordnance present and the associated contamination. Recently, DOD began to compile training range data, but these initial efforts have been delayed because DOD did not issue formal guidance to the services for collecting the information until October 2000. Because DOD has not completed an inventory of its ranges, the services have used varying methods to estimate the size and condition of the ranges necessary to estimate the cost of cleanup for financial statement purposes. As a result, environmental liability costs are not consistently calculated and reported across the services.
