Office of Legacy Management

The Department of Energy Office of Legacy Management is a civilian sub-agency within DOE that procures services and funds grants to manage and remediate closed or transferred energy facilities and environmental legacy sites. The Office executes both federal contract awards and grant programs, with activity spanning site characterization, environmental assessment, remediation oversight, financial and compliance management, and community engagement at former DOE installations and uranium-legacy properties.

The Office has issued 128 federal contract awards since 1992, with combined potential value of $1.42 billion and combined dollars obligated totaling $1.57 billion. Recent contract volume has declined sharply: 7 awards in 2022, 4 in 2023, 1 in 2024, 2 in 2025, and 1 year-to-date in 2026. The most recent award closed on October 1, 2026. Among the 50 distinct prime contractors awarded over the portfolio history, contract activity is highly concentrated by award count: RSI Entech, LLC, Deloitte Consulting LLP, Ti Verbatim Consulting Inc., Tidewater Inc., and Cohnreznick LLP account for 93 percent of awards in the last five years. RSI Entech alone holds 9 awards worth $871.6 million in combined potential value, substantially outpacing all other primes. By potential value, the top five cover 61 percent of combined value in that window, with RSI Entech again dominant. Eighty-nine percent of contract awards carry no set-aside designation; the remaining 9 percent are small-business set-asides. Recent awards with reported value are scarce; the Office has transacted heavily through task orders, modifications, or below-threshold purchase orders in recent years.

The Office has distributed 53 federal grants since 1996 with combined federal dollars obligated totaling $81.6 million. Grant awards have been episodic: 5 in 2020, 3 in 2022, 6 in 2023, 1 in 2024, and 1 in 2025. The most recent grant award closed on April 1, 2025. Among 40 distinct recipients over the portfolio history, the top five by award count (Navajo Nation Tribal Government, Pueblo of Acoma, Qawalangin Tribe of Unalaska, San Juan College, and Hopi Tribe) account for 45 percent of recent awards. Grant recipients are highly fragmented by federal dollars: the top five recipients hold only 9 percent of federal dollars obligated in the last five years, with Navajo Nation Tribal Government leading at $2.9 million. Grants are predominantly Project Grants (60 percent of awards) and Cooperative Agreements (38 percent), with one Block Grant. No recent grant opportunities are recorded.
