U.S. Department of Energy Office of Environmental Management The largest environmental cleanup program in the world. The U.S.

Department of Energy Office of Environmental Management's (EM) mission is to address the nation’s Cold War environmental legacy resulting from five decades of nuclear weapons production and government-sponsored nuclear energy research. This legacy includes some of the world’s most dangerous radioactive sites with large amounts of radioactive wastes, spent nuclear fuel, excess plutonium and uranium, thousands of contaminated facilities, and contaminated soil and groundwater. Created in 1989, EM has the responsibility for completing the cleanup of this Cold War legacy and managing the remaining nuclear materials. As the largest environmental cleanup program in the world, EM has been charged with the responsibility of cleaning up 107 sites across the country whose area is equal to the combined area of Rhode Island and Delaware. EM has made substantial progress in nearly every area of nuclear waste cleanup and has completed cleanup at 91 of these sites.

🚛 WIPP Driver Returns to Spotlight with Second National Safety Award in 2026

Tommy Cash has driven more than 3.6 million safe miles over 43 years. The WIPP waste shipment driver of 23 years was just named the 2026 Commercial Vehicle Safety Alliance International Driver Excellence Award recipient. It's his second national honor this year, following a Professional Driver of the Year award from the Truckload Carriers Association.

Cash is one of only 36 elite drivers in the U.S. entrusted with transporting transuranic radioactive waste to WIPP's underground repository. Beyond the miles, he mentors new drivers and has set such a high standard that his company has had to adapt its hiring practices to keep pace.

In September, a member of Congress presented Cash with a certificate of special congressional recognition honoring his 2026 awards. This is what the EM safety culture looks like on the road.

🌏 Walsh Advances President Trump's U.S.-Japan Energy and Nuclear Cleanup Cooperation

EM Assistant Secretary Tim Walsh recently led a delegation to Japan to strengthen nuclear cleanup and energy partnerships between the two nations.

The trip included a tour of the Fukushima Daiichi Nuclear Power Station and participation in the 10th International Forum on its decommissioning. Walsh and the delegation met with Japanese government officials and U.S. Embassy staff to advance the Trump administration's goals of energy security, nuclear cooperation and economic growth.

"Together, we are building a deeper and more connected relationship between our two nations that will benefit the United States and Japan, and the rest of the free world," Walsh said.

🏆 Celebrating EM Excellence: Secretary's Honor Awards
Seven teams and individuals across the Office of Environmental Management have earned DOE's highest honor — the Secretary's Honor Award.

Award recipients include the Oak Ridge and Portsmouth Paducah reindustrialization team, whose work is transforming EM sites into American Energy Hubs that are attracting billions in private investment and thousands of jobs. The Hanford Waste Treatment team was honored for starting up the Low-Activity Waste Facility and solidifying tank waste in glass for the first time. Two Savannah River teams were recognized for removing more than 48 million curies of radiation, deploying drones inside radioactive waste tanks and accelerating tank closures ahead of schedule.

These are the people helping to power America's nuclear future.

Demolishing a 33-acre facility requires precision timing and reliable machinery.

At the Portsmouth Site, cleanup crews created a custom equipment database to manage tools, parts and preventative maintenance for the X-333 project. From extending blade lifespans to reducing downtime, this tool maximizes taxpayer dollars and keeps cleanup on schedule.

“This groundbreaking is so much more than shifting soil.”

Members of the Scarboro community in Oak Ridge recently celebrated the start of construction on the new Elks Community Enrichment Center. Made possible by a $2.4M DOE grant, the center will offer free medical clinic space, workforce training classrooms and startup business space.

See how this project is building a brighter future:

Members of the community recently broke ground for a first-of-a-kind community enrichment center in the Scarboro community made possible by a $2.4 million Community Capacity Building Grant from the U.S. Department of Energy Office of Environmental Management.

Historic cleanup meets modern national security at Oak Ridge!

As crews prep the 313,000-square-foot Manhattan Project-era Beta-4 facility for eventual demolition, they’ve recovered over 550 reusable items—from steam heaters to power systems—to support 76 active National Nuclear Security Administration facilities. This team effort reduces environmental risk while saving valuable resources.

Read how they achieved this:

A partnership between the U.S. Department of Energy’s Oak Ridge Office of Environmental Management and the National Nuclear Security Administration is advancing preparations for future demolition of a legacy facility while recovering valuable equipment for national security missions.

Big progress at Hanford! The site is preparing to retrieve radioactive and chemical waste from its 25th underground storage tank. Tank A-103 holds roughly 385,000 gallons of legacy waste, which will be dissolved and transferred to safer, double-shell storage. This key milestone significantly reduces environmental risk and advances the cleanup mission.

Learn more:

The U.S. Department of Energy’s Hanford Field Office and contractor Hanford Tank Waste Operations & Closure are about to mark a turning point in retrieval activities by removing radioactive and chemical waste from the 25th underground storage tank.
