SUPPLEMENTARY INFORMATION:
The U.S. Nuclear Regulatory Commission (NRC) is withdrawing Draft Regulatory Guide (DG)-4037, “Preparation of Environmental Reports for Nuclear Power Stations” (Proposed Revision 5 to Regulatory Guide 4.2; ADAMS Accession No. ML25268A122). The DG-4037 was included in the proposed rule, “Modernizing Reactor Licensing, Safety Oversight, and Siting Practices” published in the
Federal Register
(FR) on July 16, 2026 (91 FR 44560).
Draft Regulatory Guide DG-4037 contains outdated and incorrect information. Accordingly, the NRC is withdrawing DG-4037 from the proposed rule and guidance; request for comment. Stakeholders should disregard DG-4037 when evaluating the “Modernizing Reactor Licensing, Safety Oversight, and Siting Practices” proposed rule. The NRC will consider whether revised or consolidated implementing guidance is warranted in the future.
