Regulatory Guide Periodic Review Number: 4.9, Revision 1 Title: Preparation of Environmental Reports for Commercial Uranium Enrichment Facilities Office/Division/Branch: NMSS/FCSE/ERB Technical Lead: Diana Diaz-Toro Staff Action Decided: Reviewed with issues identified for future consideration 1. What are the known technical or regulatory issues with the current version of the Regulatory Guide (RG)? RG 4.9 was issued in 1975, to provide specific guidance on environmental reports, for uranium enrichment facilities in order to comply with the NRC regulations in 10 CFR Part 51, "Licensing and Regulatory Policy and Procedures for Environmental Protection."

NUREG-1748 provides guidance to the NRC staff for conducting environmental reviews in support of uranium enrichment facilities. 2. What is the impact on internal and external stakeholders of not updating the RG for the known issues, in terms of anticipated numbers of licensing and inspection activities over the next several years? Although RG 4.9 is outdated and does not reflect changes to the NRC environmental review regulations in 10 CFR Part 51, there are no uranium enrichment license applications expected for the next 2-3 years where this RG could be used, and therefore there is no effect on licensing and inspection activities. However, during the next review the staff should review the most current
