SUPPLEMENTARY INFORMATION:

On April 30, 2020 (85 FR 23904), the NRC published a direct final rule amending its regulations in part 72 of title 10 of the Code of Federal Regulations to revise the Holtec International HI-STORM Flood/Wind Multipurpose Canister Storage System listing within the “List of approved spent fuel storage casks” to include Amendment No. 4 to Certificate of Compliance No. 1032. Amendment No. 4 revises the certificate of compliance to: add multipurpose canister (MPC)-32ML for storage and allow the fuel assembly class 16X16D as content for MPC-32ML; add the fuel assembly class 16X16E as content for MPC-37; and make changes to the final safety analysis report to separate the design pressure for the short-term operation from the off-normal condition (to provide clarity in Table 2.2.1), add cautionary notes to Sections 9.2.1 and 9.2.3, update a definition, and replace a test program.

In the direct final rule published on April 30, 2020, the NRC stated that if no significant adverse comments were received, the direct final rule would become effective on July 14, 2020. The NRC received and docketed one comment on the companion proposed rule (85 FR 23923; April 30, 2020). The comment can be obtained from the Federal Rulemaking website https://www.regulations.gov under Docket ID NRC-2019-0250, and from ADAMS under Accession No. ML20154K577.

The NRC evaluated the comment against the criteria described in the direct final rule and determined that the comment was not significant and adverse. Specifically, the comment was outside the scope of this rulemaking, did not oppose the rule, or did not propose a change to the rule, such that the rule would be ineffective or unacceptable without incorporation of the change. Therefore, the direct final rule will become effective as scheduled.

Dated June 25, 2020.
