Under the Department of Energy’s budget request for fiscal 2027, the DOE Office of Legacy Management would receive $200 million or $2.2 million more than in fiscal 2026.
If appropriators in the House and Senate should go along with the White House request, the Office of Legacy Management funding would represent a 1% increase over its fiscal 2026 level. Fiscal 2026 ends on Sept. 30.
Legacy Management provides long-term monitoring and stewardship to over 100 remediated sites where the federal government operated, researched, produced, and tested nuclear weapons or did engineering research.
“While these sites were remediated and placed in a safe condition, residual hazards remain after cleanup due to technical or physical limitations of the remedial work,” according to the budget justification document. Legacy Management anticipates adding over 20 new sites to its long-term stewardship portfolio over the next five years, according to the document.
The long-term sites are passed onto legacy management after cleanup is done by enties such as the DOE Office of Environmental Management or the U.S. Army Corps of Engineers.
