SUPPLEMENTARY INFORMATION: 
    On December 27, 2018 (83 FR 66585), the NRC published a direct 
final rule amending its regulations in part 72 of title 10 of the Code 
of Federal Regulations by revising the ``List of approved spent fuel 
storage casks'' to include Amendment No. 4 to Certificate of Compliance 
No. 1029 for the TN Americas LLC Standardized Advanced NUHOMS[supreg] 
Horizontal Modular Storage System. Amendment No. 4 revised the 
technical specifications of the certificate of compliance to: Clarify 
the applicability of unloading procedures and training modules relative 
to spent fuel pool availability; credit the use of the installed 
temperature monitoring system specified in lieu of performing daily 
visual vent inspections; establish dose rates on the front inlet bird 
screen and the door of the concrete storage module for the Advanced 
Horizontal Storage Module; modify the criteria for performing Advanced 
Horizontal Storage Module air vent visual inspections; identify the 
blocked vent time limitations for each of the 24PT1 and 24PT4 dry 
shielded canisters; and provide a new temperature rise value for the 
Advanced Horizontal Storage Module with a loaded 24PT4 dry shielded 
canister.
    In the direct final rule, the NRC stated that if no significant 
adverse comments were received, the direct final rule would become 
effective on March 12, 2019. As described more fully in the direct 
final rule, a significant adverse comment is a comment where the 
commenter explains why the rule would be inappropriate, including 
challenges to the rule's underlying premise or approach, or would be 
ineffective or unacceptable without a change. Because no significant 
adverse comments were received, the direct final rule will become 
effective as scheduled.

    Dated at Rockville, Maryland, this 12th day of February 2019.

    For the Nuclear Regulatory Commission.

Chief, Regulatory Analysis and Rulemaking Support Branch, Division of 
Rulemaking, Office of Nuclear Material Safety and Safeguards.
