In addition, these proposed revisions aim to reduce regulatory burden while complying with NEPA requirements. The proposed rule would narrow the scope of NEPA reviews to effects (or impacts) within the NRC's substantive statutory authority; revise definitions; update procedures for determining the level of NEPA review; establish new categorical exclusions; provide new flexibility for licensees, applicants, and petitioners for rulemaking to submit environmental information; and remove outdated requirements and consolidate content provisions to improve clarity and efficiency.
