2015-31254. Assessment of Radioactive Discharges in Ground Water to the Unrestricted Area at Nuclear Power Plant Sites
-
Start Preamble
AGENCY:
Nuclear Regulatory Commission.
ACTION:
Draft regulatory guide; request for comment.
SUMMARY:
The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment draft regulatory guide (DG), DG-4025, “Assessment of Radioactive Discharges in Ground Water to the Unrestricted Area at Nuclear Power Plant Sites.” This DG proposes guidance for an approach that the NRC staff considers acceptable for use in assessing abnormal, inadvertent radioactive releases that may result in discharges of contaminated ground water from the subsurface to the unrestricted area at commercial nuclear power plant sites.
DATES:
Submit comments by February 9, 2016. Comments received after this date will be considered if it is practical to do so, but the NRC is able to ensure consideration only for comments received on or before this date. Although a time limit is given, comments and suggestions in connection with items for inclusion in guides currently being developed or improvements in all published guides are encouraged at any time.

B. Submitting Comments
Please include Docket ID NRC-2015-0272 in your comment submission.
The NRC cautions you not to include identifying or contact information that you do not want to be publicly disclosed in your comment submission. The NRC posts all comment submissions at http://www.regulations.gov as well as entering the comment submissions into ADAMS. The NRC does not routinely edit comment submissions to remove identifying or contact information.
If you are requesting or aggregating comments from other persons for submission to the NRC, then you should inform those persons not to include identifying or contact information that they do not want to be publicly disclosed in their comment submission. Your request should state that the NRC does not routinely edit comment submissions to remove such information before making the comment submissions available to the public or entering the comment submissions into ADAMS.
II. Additional Information
The NRC is issuing for public comment a DG in the NRC's “Regulatory Guide” series. This series was developed to describe and make available to the public information regarding methods that are acceptable to the NRC staff for implementing specific parts of the NRC's regulations, techniques that the staff uses in evaluating specific issues or postulated events, and data that the staff needs in its review of applications for permits and licenses.
The DG, entitled, “Assessment of Radioactive Discharges in Ground Water to the Unrestricted Area at Nuclear Power Plant Sites” is a proposed new Start Printed Page 77029guide temporarily identified by its task number, DG-4025. This guidance provides an approach acceptable to the NRC for licensees to satisfy the regulatory requirements for reporting subsurface radioactive discharges to offsite areas. The approach can be used for assessing abnormal, inadvertent radioactive releases that may result in discharges of contaminated ground water from the subsurface to the unrestricted area at commercial nuclear power plant sites.
II. Backfitting and Issue Finality
This DG-4025 describes a method that the staff of the NRC considers acceptable for assessing abnormal, inadvertent radioactive releases which may result in discharges of contaminated ground water from the subsurface to the unrestricted area at commercial nuclear power plant sites. Issuance of this DG, if finalized, would not constitute backfitting as defined in section 50.109 of Title 10 of the Code of Federal Regulations (10 CFR), “Backfitting” (the Backfit Rule) and would not otherwise be inconsistent with the issue finality provisions in 10 CFR part 52. As discussed in the “Implementation” section of this DG, the NRC has no current intention to impose this guide, if finalized, on holders of current operating licenses or combined licenses.
This DG may be applied to applications for operating licenses, combined licenses, early site permits, and certified design rules docketed by the NRC as of the date of issuance of the final regulatory guide, as well as future applications submitted after the issuance of the regulatory guide. Such action would not constitute backfitting as defined in the Backfit Rule or be otherwise inconsistent with the applicable issue finality provision in 10 CFR part 52, inasmuch as such applicants or potential applicants are not within the scope of entities protected by the Backfit Rule or the relevant issue finality provisions in 10 CFR part 52.
