Freedom of Information Act

The Defense Nuclear Facilities Board's (the Board or DNFSB) published a proposed rule to amend its Freedom of Information Act (FOIA) regulations on November 24, 2025, with a request for comments. The Board did not receive any public comments, and the proposed rule is adopted in this action as a final rule without change. This final rule incorporates certain changes made by the OPEN Government Act of 2007 and the FOIA Improvement Act of 2016. This final rule also amends certain provisions to reflect developments in case law and changes in position titles to align with changes made by the National Defense Authorization Act (NDAA) for Fiscal Year (FY) 2022 to the Atomic Energy Act of 1954 (AEA) and an agency reorganization. The final rule amends a section to permit submission of FOIA requests by electronic mail to the Board or via the government-wide portal. This final rule also adds multitrack processing, which allows the Board to quickly process simple requests. Finally, the final rule defines what information should be included in a denial letter.
