BLUF: The Department of Energy obligated $169.4 million to Savannah River Mission Completion, LLC on August 13, 2026, funding liquid-waste operations under Task Order 6 of the Savannah River Integrated Mission Completion Contract.

The obligation, recorded as contract modification P00058, follows a separate $50.25 million modification (P00057) signed just three days earlier, on August 10, 2026, which added a new cost-plus-fixed-fee CLIN to the same task order to cover FY26–FY32 utility, material-handling, and procurement costs. Together, the two actions moved more than $219 million onto the task order inside a single week. Both modifications were funded under the same underlying task order, award ID 89303723FEM400292, issued against the single-award IDIQ contract 89303322DEM000068.

Why it matters: DOE's Office of Environmental Management continues to fund Savannah River liquid-waste cleanup work in large, frequent increments rather than a single lump-sum obligation, a pattern contractors tracking DOE EM spending should watch for signals on program funding velocity. The task order's cost-plus-fixed-fee structure means recipient compensation is tied to allowable costs plus a fixed fee, and the recurring CLIN additions indicate the scope of billable work is still being actively defined years into contract performance. Full-and-open competition on the underlying task order, with no set-aside designation, means this remains large-business-only work in the near term.

By the numbers:

• $169,400,000 obligated August 13, 2026 (modification P00058)
• $50,250,000 obligated August 10, 2026 (modification P00057)
• $2,423,613,818.72 total obligated to date on task order 89303723FEM400292 (as of this report)
• $7,712,499,422 contract ceiling (base plus all options)
• Period of performance: October 1, 2023 – October 26, 2031
• NAICS 562910 (Remediation Services)
• Awarded via full and open competition; no small-business set-aside

The task order, formally titled the Savannah River Integrated Mission Completion Contract — Task Order 6 (Liquid Waste Operations), was originally signed September 13, 2023, and has since been modified more than 58 times, according to USAspending.gov transaction records. Modification P00058's stated purpose was simply "to obligate funding to Task Order 6 for liquid waste," while P00057 both added the new CLIN and obligated funds against it. The task order sits under a single-award indefinite-delivery contract held with the Department of Energy's Savannah River operations.
