SUMMARY: The U.S. Nuclear Regulatory Commission (NRC or Commission) is 
issuing a revision to Regulatory Guide (RG) 1.160, ``Monitoring the 
Effectiveness of Maintenance at Nuclear Power Plants.'' This guide 
endorses Revision 4A to Nuclear Management and Resources Council

Regulations (10 CFR) 50.65, ``Requirements for Monitoring the 
Effectiveness of Maintenance at Nuclear Power Plants,'' Part 50, 
``Domestic Licensing of Production and Utilization Facilities.'' 
Revision 4 of NUMARC 93-01 provides enhanced clarity regarding scoping 
non-safety related Systems, Structures and Components based on their 
use in Emergency Operating Procedures, gives guidance on consideration 
of fire risk in (a)(4) risk assessments, and provides enhanced 
consistency in unavailability monitoring between the Maintenance Rule 
and Reactor Oversight process by providing clarification to the 
definition for monitoring of short term unavailability resulting from 
periodic system or equipment realignments.

SUPPLEMENTARY INFORMATION: The NRC is issuing a revision to an existing

developed to describe and make available to the public information such 
as methods that are acceptable to the NRC staff for implementing 
specific parts of the agency's regulations, techniques that the staff 
uses in evaluating specific problems or postulated accidents, and data 
that the staff needs in its review of applications for permits and 
licenses.
    Revision 3 of RG 1.160 was issued with a temporary identification 
as Draft Regulatory Guide, DG-1278. This regulatory guide endorses 
NUMARC 93-01 which provides methods that are acceptable to the NRC 
staff for complying with the provisions of Section 50.65, 
``Requirements for Monitoring the Effectiveness of Maintenance at 
Nuclear Power Plants,'' of 10 CFR Part 50.

public comments are available under ADAMS Accession Number ML11321A272.
