NUCLEAR REGULATORY COMMISSION


Office of New Reactors; Interim Staff Guidance on Assessment of 
Normal and Extreme Winter Precipitation Loads on the Roofs of Seismic 
Category I Structures

AGENCY: Nuclear Regulatory Commission (NRC).

ACTION: Solicitation of public comment.

-----------------------------------------------------------------------

SUMMARY: The NRC is soliciting public comment on its Proposed Interim 
Staff Guidance (ISG) DC/COL-ISG-07 (ADAMS Accession No. ML081980084). 
The purpose of this ISG is to clarify the NRC position on identifying 
winter precipitation events as site characteristics and site parameters 
for determining normal and extreme winter precipitation loads on the 
roofs of Seismic Category I structures. This ISG revises the previously 
issued staff guidance in March 2007 in the Standard Review Plan (SRP) 
NUREG-0080, ``Standard Review Plan for the Review of Safety Analysis 
Reports for Nuclear Power Plants.'' The NRC staff issues DC/COL-ISGs to 
facilitate timely implementation of the current staff guidance and to 
facilitate activities associated with review of applications for design 
certifications (DCs) and combined licenses (COLs) by the Office of New 
Reactors. The NRC staff will also incorporate the approved DC/COL-ISG-
007 into the next revision of the SRP and related guidance documents.

DATES: Comments must be filed no later than 30 days from the date of 
publication of this notice in the Federal Register. Comments received 
after this date will be considered, if it is practical to do so, but 
the Commission is able to ensure consideration only for comments 
received on or before this date.

ADDRESSES: Comments may be submitted to: Chief, Rulemaking, Directives 
and Editing Branch, Office of Administration, U.S. Nuclear Regulatory 
Commission, Washington, DC 20555-0001.
