II. Discussion

NEDA is the holder of Renewed Facility Operating License No. DPR-49 for DAEC. The license provides, among other things, that the facility is subject to all rules, regulations, and orders of the NRC now or hereafter in effect. The facility consists of one boiling-water reactor located adjacent to the Cedar River approximately 2.5 miles northeast of the town of Palo in Linn County, Iowa. By letter dated January 18, 2019 (ADAMS Accession No. ML19023A196), the licensee submitted its notification of permanent cessation of power operations for DAEC. In this letter, NEDA notified the NRC of its intent to permanently cease power operations at DAEC in the fourth quarter of 2020. By letter dated March 2, 2020 (ADAMS Accession No. ML20062E489), the licensee submitted a revised notification of permanent cessation of power operations for DAEC. In this letter, NEDA notified the NRC of its intent to permanently cease power operations at DAEC on October 30, 2020.

On April 2, 2020, NEDA submitted the PSDAR, including the site-specific DCE for DAEC, in accordance with § 50.82(a)(4)(i) of title 10 of the Code of Federal Regulations (ADAMS Accession No. ML20094F603). The PSDAR includes a description of the planned decommissioning activities, a proposed schedule for their accomplishment, the site-specific DCE, and a discussion that provides the basis for the NRC to conclude that the environmental impacts associated with the site-specific decommissioning activities will be bounded by appropriate, previously issued generic and plant-specific environmental impact statements.

III. Request for Comment and Public Meeting

Due to the COVID-19 Public Health Emergency (PHE), the NRC has delayed holding a public meeting to obtain comments from the public on the DACE PSDAR, including the DCE. However, with recent announcements for relaxing PHE restrictions by Iowa Governor Reynolds, the NRC is tentatively planning to hold the PSDAR meeting and receive comments on Tuesday, July 28, 2020, from 6 p.m. until 9 p.m., at the Palo Community Center, 2800 Hollenbeck Rd, Palo, Iowa 52324. If PHE restrictions do not allow the meeting to be held on July 28, 2020, the NRC will notify the public by revising the date on the NRC Public Meeting Schedule on the NRC's public website at​pmns/​mtg. The NRC requests that comments provided outside the July 28, 2020 meeting be submitted as noted in Section I, “Obtaining Information and Submitting Comments,” of this document in writing by October 19, 2020.
