I. Introduction

    Regulatory guides may be withdrawn by the NRC when their guidance 
no longer provides useful information, or is superseded by 
technological innovations, congressional actions, or other events. The 
NRC is withdrawing RG 1.167 because its guidance has been incorporated 
into RG 1.166, ``Pre-Earthquake Planning, Shutdown, and Restart of a 
Nuclear Power Plant Following an Earthquake'' (ADAMS Accession No. 

II. Further Information

    The withdrawal of RG 1.167 does not alter any prior or existing NRC 
licensing approval or the acceptability of licensee commitments to this 
RG. Although RG 1.167 is withdrawn, current licensees may continue to 
use it, and withdrawal does not affect any existing licenses or 
agreements. However, by withdrawing RG 1.167, the NRC no longer 
approves the guidance in this RG for use in future requests or 
applications for NRC licensing actions.

    Dated at Rockville, Maryland, this 14th day of February 2020.

    For the Nuclear Regulatory Commission.
