Hanford Awards Grout Subcontracts to Expand Cleanup Capabilities

RICHLAND, Wash. – The U.S. Department of Energy’s Hanford Field Office contractor Hanford Tank Waste Operations and Closure (H2C) has awarded three subcontracts that expand the site’s capabilities for the future disposition of tank-side treated waste, providing additional tools to support Hanford’s cleanup mission.

The awards were made to Perma-Fix, EnergySolutions and Waste Control Specialists to support future tank-side treated waste generated from Hanford’s 200 West Area. Together, the contracts establish commercial grouting capabilities that can be deployed as cleanup needs evolve while maintaining safe, compliant waste disposition options.

The subcontractors also provide the capability to grout concentrate produced by the Effluent Management Facility beginning in 2027, while supporting planning for additional treated waste streams and future transport methods.

“Successful cleanup requires the flexibility to apply the right solution to the right waste stream,” said Hanford Field Office Manager Ray Geimer. “These subcontract awards expand our options and strengthen our ability to safely manage treated waste as the mission progresses.”

The awards establish commercial capability that can be used as future disposition decisions are implemented following required environmental reviews, regulatory approvals and legal commitments.

Expanding available treatment and disposal options supports Hanford’s long-term cleanup mission by providing greater operational flexibility while continuing to protect workers, the public and the environment. The approach aligns with the Department of Energy Office of Environmental Management’s commitment to restoration and revitalization by reducing risk and advancing cleanup across the site.
