Amentum’s United Cleanup Oak Ridge LLC Begins Critical Work at Oak Ridge Reservation


New UCOR Begins Operating Under New Contract

GERMANTOWN, Md., (May 24, 2022) – Amentum, a leading contractor to U.S. federal and allied governments, announced that its newly formed United Cleanup Oak Ridge LLC (UCOR) officially took over cleanup operations at the U.S. Department of Energy’s Oak Ridge Reservation in Tennessee. UCOR is a joint venture among Amentum, Jacobs, and Honeywell. The team includes four pre-selected small businesses, RSI EnTech, Strata-G, Longnecker & Associates and Environmental Alternatives, Inc.

The UCOR transition activities were recently completed, and the declaration of readiness was signed off last week. Under the leadership of Ken Rueter, UCOR will  be responsible for cleanup and remedial actions at the East Tennessee Technology Park (ETTP); cleanup of excess facilities at the Oak Ridge National Laboratory and the Y-12 National Security Complex; design, construction, and operation of the new onsite disposal facility – the Environmental Management Disposal Facility; operational activities and surveillance and maintenance for multiple facilities; and core functions for central and project services.  Completion of this contract will not only deliver environmental risk reduction but enable historic preservation, conservation, and future economic development in East Tennessee.  The company’s nearly 2,000 workers are dedicated to safely reducing environmental risk on the Oak Ridge Reservation while helping DOE’s Office of Science and NNSA continue their enduring national science and defense missions.

The UCOR contract is a single award Indefinite-Delivery/Indefinite-Quantity contract with a 10-year ordering period with an estimated contract ceiling of approximately $8.3 billion. It is anticipated that task order performance may extend up to five years beyond the end of the ordering period (for a potential 15-year period of performance). The new contract resulting from this acquisition will replace the ETTP contract awarded to Amentum led URS|CH2M Oak Ridge LLC in 2011.

“The new team at UCOR continues to facilitate the future of East Tennessee’s economic development by delivering superior environmental stewardship work at the Oak Ridge Reservation,” said Mark Whitney, President of Amentum’s Environment & Energy business. “Building off the success of our previous contract, our new team will continue achieving historic milestones in environmental remediation for the Department of Energy, the Oak Ridge community and other stakeholders in advancing this critical work.”
