II. Discussion

On December 19, 2022, the NRC issued a Federal Register notice (87 FR 77643) detailing its intent to conduct an additional limited scoping process to gather information necessary to prepare a supplement to its EIS to evaluate the environmental impacts of SLR of Renewed Facility Operating License Nos. DPR-38, DPR-47, and DPR-55 for Oconee.

By letter dated June 7, 2021, Duke Energy Carolinas, LLC (Duke Energy, the applicant) submitted to the NRC an application for subsequent license renewal of Renewed Facility Operating License Nos. DPR-38, DPR-47, and DPR-55 for Oconee, Units 1, 2, and 3 (ADAMS Package Accession No. ML21158A193). Later, the NRC received Subsequent License Renewal—Appendix E Environmental Report Supplement 2 (ER Supplement), dated November 7, 2022 (ADAMS Accession No. ML22311A036), in response to NRC's Memorandum and Order, CLI-22-03 (February 24, 2022) (ADAMS Accession No. ML22055A554). The NRC staff intends to prepare a Draft Supplemental Environmental Impact Statement (DSEIS) for Oconee subsequent license renewal. The subsequent renewed operating licenses would authorize the applicant to operate Oconee for an additional 20 years beyond the period specified in each of the current licenses.

The NRC is conducting an additional limited scoping process to gather information necessary to prepare a supplement to its EIS to evaluate the environmental impacts of SLR of the operating licenses for Oconee. The NRC is seeking public comment on the proper scope of the EIS supplement to be prepared for this action.

The public comment period was originally scheduled to close on January 18, 2023. The NRC has decided to extend the public comment period until February 2, 2023, to allow more time for members of the public to submit their comments. Comments of Federal, State, and local agencies, Indian Tribes or other interested persons will be made available for public inspection when received.
