Start Preamble

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.
