The US Nuclear Regulatory Commission (NRC) has proposed a comprehensive update to its environmental review regulations, narrowing environmental reviews to impacts within the agency’s statutory authority and expanding opportunities to streamline licensing for new nuclear projects while maintaining environmental protections. The proposal also expands the use of categorical exclusions for certain actions, including some new reactor projects, where NRC has determined they normally do not result in significant environmental impacts.
“This proposal focuses our environmental reviews on what matters most,” Chairman Ho K Nieh said. “By concentrating on impacts the NRC can address, we’ll strengthen environmental protection while making licensing reviews more timely and predictable.”
Together with the NRC’s recently completed rules on categorical exclusions and generic environmental findings for new reactors, this proposal represents a significant modernisation of environmental regulations. NRC said collectively, these actions create a more focused, efficient and predictable framework for reviewing future nuclear projects while maintaining compliance with the National Environmental Policy Act and the NRC’s environmental responsibilities.
The proposal implements recent amendments to the law, reflects recent court decisions and advances the regulatory modernisation goals of the May 2025 Executive Order 14300, Ordering the Reform of the Nuclear Regulatory Commission. NRC will accept public comments until 21 August. NRC is collaborating with interagency partners to implement reforms outlined in new Executive Orders and the ADVANCE Act to streamline agency activities and enhance efficiency.
