Environmental Liabilities: DOE Needs to Better Plan for Post-Cleanup Challenges Facing Sites, Report to the Committee on Armed Services, U.S. Senate   [open pdf - 3MB]

From the GAO [Government Accountability Office] Highlights: "After over 70 years of nuclear weapons production and energy research at hundreds of sites across the country, DOE [Department of Energy] faces over $500 billion in environmental liabilities associated with cleanup of hazardous contamination and long-term management of these sites. LM [Office of Legacy Management] is responsible for the portion of these liabilities associated with long-term management of sites after active cleanup has been completed. LM oversees 100 sites across the country. Depending on the sites' clean-up standards and intended reuse, LM will likely be managing some sites for centuries. Senate Report 116-48 accompanying the National Defense Authorization Act for fiscal year 2020 includes a provision for GAO to review LM's operations, including the nature of its environmental liability. This report examines (1) LM's environmental liability, and (2) any challenges LM faces in managing its sites and how it is addressing those challenges. GAO analyzed data on LM's environmental liability; interviewed officials at LM headquarters and those responsible for the nine sites requiring the most intensive level of management; and reviewed relevant policies, procedures, and guidance."
