## Abstract

The Nuclear Regulatory Commission (NRC) is confirming the effective date of November 5, 2001, for the direct final rule that appeared in the Federal Register of August 21, 2001 (66 FR 43761). This direct final rule amended the NRC's regulations revising the "List of Approved Spent Fuel Storage Casks" by terminating Certificate of Compliance Number 1001 for the Westinghouse MC-10 cask system. The Westinghouse MC-10 can no longer be used to store spent fuel under a general license. This document confirms the effective date.
