# Hanford Contractor Settles DOE Fraud Suit

Hanford Mission Integration Solutions (HMIS), a joint venture of Leidos, Centerra, and Parsons, agreed to pay the Department of Justice **$3.45 million** to resolve allegations that it billed the Department of Energy for excessive idle labor under its Hanford Site-services work. The case concerns cost-reimbursement billing on a DOE contract awarded in 2019 and underscores the False Claims Act exposure contractors may face when labor charges are challenged.

- DOE site-services contractors should review labor assignments, timekeeping, and billing controls, particularly for idle or unproductive labor charged to cost-reimbursement work.
- The matter highlights the importance of maintaining records that support billed labor and demonstrate consistency between work performed and charges submitted to the government.
- The settlement is relevant to firms pursuing environmental cleanup and other DOE work because billing practices can create substantial financial and legal risk alongside contract performance obligations.
