Correction, September 22, 2026: An earlier version described the more than $950 million FY 2026 maintenance figure as actual spending. It was the budget request. The headline, summary and comparison below have been corrected to distinguish requested funding from expenditures.

Requested funding rose while the underlying condition data remained weak

GAO’s May 5, 2026 review says the Department of Energy’s environmental cleanup complex included about 4,300 operating facilities and more than $1.5 billion in identified repair needs as of June 2025. DOE’s budget request included more than $950 million for direct-funded maintenance and repairs in fiscal 2026, roughly 80% above fiscal 2020 actual spending.

The FY 2026 figure is a request, not a verified expenditure total. GAO’s chart distinguishes actual spending for fiscal 2020–2024 from estimates for fiscal 2025–2026; the comparison does not establish how much DOE ultimately spent in fiscal 2026.

The accountability problem was not simply the size of the bill. GAO found some facility-condition scorecards inaccurate or unsupported and found incomplete corrective-action plans, weakening the records used to prioritize repairs.

Local plans did not fully reach headquarters

Officials at eight of 13 cleanup sites told GAO that DOE’s master asset plan did not include all of their infrastructure needs. That disconnect can cause headquarters and Congress to see a cleaner portfolio than site managers say they must maintain.

GAO also identified 19 cost-saving projects that sites said could yield about $120 million in savings, but DOE had not communicated them to Congress in the way GAO expected. Potential savings are estimates, not money already recovered.

What the records establish

The combined accountability picture is that DOE requested substantially more maintenance funding than it spent in fiscal 2020, documented repair needs exceeded $1.5 billion, and the scorecards used for prioritization were not consistently reliable. These data gaps limit the information available to Congress when comparing risk and funding across sites.

The findings do not mean every facility is unsafe or that a radiological release occurred. GAO evaluated asset management and reporting; it did not issue a blanket engineering judgment on all 4,300 facilities.

Method and limits

GAO analyzed DOE records, site plans and scorecards and obtained information from cleanup sites. This newsroom checked the figures against GAO’s official product page and full report, including the actual-versus-estimated labels in the maintenance chart. Repair needs, requested maintenance funding, actual spending and projected savings are different measures.

Facility counts and repair estimates can change as buildings close, new deficiencies are found or project scopes are refined. The $120 million figure describes potential savings from identified projects, not audited realized savings.
