Download as PDF 49712 Federal Register / Vol. 73, No. 164 / Friday, August 22, 2008 / Notices jlentini on PROD1PC65 with NOTICES PWROG views changes in Addendum A substantial enough to warrant an extension of the public review period. Accordingly, we request a 60-day extension to the current review period.’’ Response to Request The request for an extension to the comment period is approved for 30 days. The staff understands that ASME/ ANS is working on an initial addendum (i.e., Addendum A) to Revision 1 of the ASME/ANS PRA Standard (RA–S– 2008). However, at this time, Addendum A has not been approved by ASME/ANS, and consequently is not available to the public. Since the ASME/ ANS ballot period has not closed, it is not known if there will be sufficient positive ballots approving Addendum A. Consequently, it is uncertain if and when ASME/ANS will issue Addendum A, and therefore, be available to the public. A 60-day extension to the public comment period for DG 1200 will impact the December 2008 publication date of Revision 2 of RG 1.200. With the uncertainty associated with the issuance of Addendum A of the ASME/ANS PRA standard, the staff does not support an extension of the comment period to DG 1200 that would impact the schedule for publishing Revision 2 to RG 1.200. However, the staff agrees with the PWROG with regard to the importance of Addendum A. The staff understands from ASME that the ballot closes September 12, 2008, at which time the status of Addendum A will be known. A 30-day extension to the comment period of DG 1200 will enable the staff the meet the publication schedule of December 2008 for Revision 2 to RG 1.200. Therefore, the staff is approving a 30-day extension to the public comment period, with the public comment period to end on September 24, 2008. Further, at that time, the status of Addendum A of the ASME/ANS PRA Standard will be known, and dependent on the content of Addendum A and the schedule for issuance, the staff may revisit the schedule for publishing Revision 2 of RG 1.200. Requests for technical information about DG–1200 may be directed to the NRC contact, Mary Drouin at (301) 415– 6675 or e-mail to Mary.Drouin@nrc.gov. Electronic copies of DG–1200 are available through the NRC’s public Web site under Draft Regulatory Guides in the ‘‘Regulatory Guides’’ collection of the NRC’s Electronic Reading Room at http://www.nrc.gov/reading-rm/doccollections/. Electronic copies are also available in ADAMS (http:// www.nrc.gov/reading-rm/adams.html), under Accession No. ML081200566.

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

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
