Hanford Mission Integration Solutions (HMIS) agreed to a $3.45 million settlement to resolve allegations that it submitted inflated labor hours and overcharged the Department of Energy under the False Claims Act. The settlement resolves claims of improper billing for labor at the Hanford nuclear site and returns federal funds to the government.

The U.S. Attorney’s Office for the Eastern District of Washington announced that Hanford Mission Integration Solutions (HMIS) agreed to a $3.45 million settlement to resolve allegations under the False Claims Act that the contractor overbilled the Department of Energy by submitting inflated labor hours. The civil action arose from audits and investigations into timekeeping and charge practices on contracts supporting operations at the Hanford nuclear reservation. DOJ said the resolution repays federal funds allegedly obtained through improper billing practices and will be used to recoup taxpayer losses tied to labor mischarging. The settlement implements internal controls and record‑keeping expectations and may include provisions for monitoring and compliance enhancements to prevent recurrence. DOJ framed the agreement as part of continuing oversight of contractors engaged in federal cleanup and support missions, stressing accountability where contract billing deviates from statutory and regulatory requirements. The release noted the case resolved allegations without admission of liability by HMIS, while preserving the government’s ability to pursue parallel or related claims if further evidence emerges.
