Start Preamble

AGENCY:

Nuclear Regulatory Commission (NRC).

ACTION:

Reopening of comment period.

SUMMARY:

The NRC published a request for public comment in the Federal Register on May 4, 2009, on proposed Interim Staff Guidance (ISG) DC/COL-ISG-013, “Assessing the Consequences of an Accidental Release of Radioactive Materials from Liquid Waste Tanks” (Agencywide Documents Access and Management System (ADAMS) Accession No. ML090830488). The NRC has completed a related ISG, DC/COL-ISG-014, “Assessing Ground Water Flow and Transport of Accidental Radionuclide Releases,” and is making it available for public comment by separate document published today in the Federal Register. The NRC believes that the public will be better served by being able to review and comment on both documents at this time. This action is necessary to reopen the comment period for ISG DC/COL-ISG-013.

ADDRESSES:

Please include Docket ID NRC-2009-0189 in the subject line of your comments. Comments submitted in writing or in electronic form will be posted on the NRC Web site and on the Federal rulemaking Web site Regulations.gov.

The NRC requests that any party soliciting or aggregating comments received from other persons for submission to the NRC inform those persons that the NRC will not edit their comments to remove any identifying or contact information, and therefore, they should not include any information in their comments that they do not want publicly disclosed.Start Printed Page 8412

SUPPLEMENTARY INFORMATION:

The NRC requested public comment on May 4, 2009 (74 FR 20510), on its Proposed Interim Staff Guidance (ISG) DC/COL-ISG-013 (ADAMS Accession No. ML090830488). The purpose of this ISG is to modify and provide Combined License (COL) and Design Certification (DC) applicants additional clarity and guidance for the application of Standard Review Plan (SRP) Sections 11.2 and 2.4.13 on the characterization of hydro geological properties of a site associated with the effects of accidental releases of radioactive liquid on existing or likely future uses of ground and surface water resources in meeting the requirements of Title 10 of the Code of Federal Regulations, Part 100 (10 CFR 100.10 or 100.20) and Appendix B to 10 CFR part 20 on effluent concentration limits. This ISG would revise the staff guidance previously issued in March 2007 in the SRP NUREG-0080, “Standard Review Plan for the Review of Safety Analysis Reports for Nuclear Power Plants,” Sections 11.2 and 2.4.13. These two SRP sections are not internally consistent in identifying acceptable criteria for assessing the consequences of accidental releases of radioactive materials, or in providing guidance to the staff and applicants to establish conditions for such releases and define acceptable assumptions to describe exposure scenarios and pathways to members of the public. The NRC staff issues DC/COL-ISGs to facilitate timely implementation of current staff guidance and to facilitate activities associated with review of applications for DCs and COLs by the Office of New Reactors. The NRC staff will also incorporate the approved DC/COL-ISG-013 into the next revision of the SRP and related guidance documents.

The NRC staff is issuing this notice to reopen the public comment period for proposed DC/COL-ISG-013. After the NRC staff considers all public comments, it will make a determination regarding proposed DC/COL-ISG-013. The agency posts its issued staff guidance on the agency's Web site at http://www.nrc.gov/​reading-rm/​doc-collections/​isg/​.
