The Office of Information and Regulatory Affairs (OIRA) is under the Office of Management Budget, which is part of the Executive Office of the President. Executive order, “Ensuring Accountability for All Agencies” (EO 14215), issued on February 24th, 2025, requires all independent safety agencies to undergo an OIRA review. The Nuclear Regulatory Commission (NRC) must now submit its rulemaking and guidance for a significance determination. If determined to be significant, a proposed rule would go through the EO 12866 OIRA review process that has governed all traditional cabinet departments and agencies since 1993. The purpose of this tracker is to provide insight into the additional impact on the timeline that the OIRA process adds to rulemaking.
