The Nuclear Regulatory Commission (NRC) is amending its regulations to require the use of electronic submissions in all agency hearings, consistent with the existing practice for the high-level radioactive waste repository application (which is covered under a separate set of regulations). The amendments require the electronic transmission of electronic documents in submissions made to the NRC's adjudicatory boards. Although exceptions to these requirements are established to allow paper filings in limited circumstances, the NRC maintains a strong preference for fully electronic filing and service. The rule builds upon prior NRC rules and developments in the Federal courts regarding the use of electronic submissions.
