SUPPLEMENTARY INFORMATION: On July 25, 2005 (70 FR 42485), the NRC 
published a direct final rule amending its regulations in 10 CFR part 
72 to revise the NAC-UMS cask system listing within the ``List of 
Approved Spent Fuel Storage Casks'' to include Amendment No. 4 to CoC 
No. 1015. This amendment replaces the term ``zircaloy'' with the more 
generic term ``zirconium alloy'; revises the definitions of 
``operable'' and ``site specific fuel''; revises vacuum drying pressure 
and time limits; revises short-term temperature limits and completion 
times for the heat removal system; clarifies the surface dose rate 
surveillance; adds a dissolved boron concentration option; deletes a 
redundant boron concentration administrative control; adds an alternate 
site-specific design basis earthquake analysis; and incorporates 
editorial and administrative changes. In the direct final rule, NRC 
stated that if no significant adverse comments were received, the 
direct final rule would become final on October 11, 2005. The NRC did 
not receive any comments that warranted withdrawal of the direct final 
rule. Therefore, this rule will become effective as scheduled.

    Dated at Rockville, Maryland, this 18th day of September, 2005.

    For the Nuclear Regulatory Commission.
Michael T. Lesar,
Chief, Rules and Directives Branch, Division of Administrative 
Services, Office of Administration.
