SUPPLEMENTARY INFORMATION:

On November 9, 2020, the NRC published a direct final rule (85 FR 71223) amending its regulations in part 72 of title 10 of the Code of Federal Regulations for the Holtec International HI-STORM UMAX Canister Storage System listing in the “List of approved spent fuel storage casks” to include Amendment No. 4 to Certificate of Compliance No. 1040. Amendment No. 4 revises the certificate of compliance to update the technical specifications for radiation protection regarding the dose rate limit for the vertical ventilated module lid, update the technical specifications for the vent blockage limiting condition for operation, and add a Type 1 version of multi-purpose canister MPC-37.

In the direct final rule, the NRC stated that if no significant adverse comments were received, the direct final rule would become effective on January 25, 2021. The NRC received and docketed one comment on the companion proposed rule (85 FR 71274, November 9, 2020). An electronic copy of the comment can be obtained from the Federal Rulemaking website at https://www.regulations.gov under Docket ID NRC-2020-0179 and is also available in ADAMS under Accession No. ML20349A179.

The NRC evaluated the comment against the criteria described in the direct final rule and determined that it was not significant and adverse. Specifically, the comment was outside the scope of this rulemaking and did not oppose the rule; propose a change or an addition to the rule; or cause the NRC to make a change to the rule, the certificate of compliance, or the technical specifications. Therefore, this direct final rule will become effective as scheduled.
