II. Background In accordance with the Paperwork Reduction Act of 1995 (44 U.S.C. Chapter 35), the NRC is requesting public comment on its intention to request the OMB’s approval for the information collection summarized below. 1.

The form number, if applicable: NRC Form 536. 5. How often the collection is required or requested: Annually. 6. Who will be required or asked to respond: (a) All holders of operating licenses for nuclear power reactors under the provision of title 10 of the Code of Federal Regulations (10 CFR) Part 50, ‘‘Domestic Licensing of Production and Utilization Facilities,’’ except those that have permanently ceased operations and have certified that fuel has been permanently removed from the reactor vessel. (b) All holders of, or applicants for, a limited work authorization, early site permit, or combined licenses issued under 10 CFR part 52, ‘‘Licenses, Certifications and Approval for Nuclear Power Plants.’’ 7. The estimated number of annual responses: 100. 8. The estimated number of annual respondents: 100. 9. The estimated number of hours needed annually to comply with the information collection requirement or request: 75 (0.75 hour per form × 100). 10. Abstract: The NRC is requesting renewal of its clearance to annually request all commercial power reactor licensees and applicants for an operating license to voluntarily send to the NRC: (1) Their projected number of candidates for initial operator licensing examinations; (2) the estimated dates of the examinations, and (3) if the examinations will be facility developed or NRC developed.

Discussion The NRC is issuing a new guide 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 agency’s regulations, techniques that the NRC staff uses in evaluating specific issues or postulated events, and data that the NRC staff needs in its review of applications for permits and licenses. Revision 0 of RG 4.25 was issued with a temporary identification of Draft Regulatory Guide, DG–4025. The guide is being issued to provide guidance to licensees on acceptable methods to determine the quantity of licensed material (i.e., radionuclides) in abnormal discharge into the unrestricted area through the ground water discharge pathway at commercial nuclear power plants. American National Standards Institute/American Nuclear Society (ANSI/ANS)–2.17–2010 (R2016), ‘‘Evaluation of Subsurface Radionuclide Transport at Commercial Nuclear Power Plants,’’ provides such methods. The E:\FR\FM\15MRN1.SGM 15MRN1 13876 Federal Register / Vol. 82, No. 49 / Wednesday, March 15, 2017 / Notices ANSI/ANS standard does not specify the use of any specific ground water flow and transport model. It provides a graded, risk-informed approach for evaluating the effects of subsurface radionuclide transport. The ground water flow and transport model developed by licensees should be a sitespecific model, based on the complexity of geologic and hydrologic conditions, the types of radioactive materials and facility design, the types and effectiveness of engineered and natural barriers, and the proximity to surface water and ground water receptors. A facility that has less significant radionuclide source term, minor subsurface contamination, simple or well-understood hydrogeology, or limited effects on ground water resources generally requires less extensive site characterization, mathematical modeling, and performance-confirmation measures than a facility with significant residual radioactivity that has the potential to exceed national radiation protection standards. The appendix to RG 4.25 provides a simple ground water flow and transport model that is acceptable for use with simple hydrogeologic conditions and geometry such as steadystate saturated flow in homogeneous porous sand layers.

SUPPLEMENTARY INFORMATION:

I. Discussion

    The NRC is issuing a new guide 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 agency's regulations, 
techniques that the NRC staff uses in evaluating specific issues or 
postulated events, and data that the NRC staff needs in its review of 
applications for permits and licenses.
    Revision 0 of RG 4.25 was issued with a temporary identification of 
Draft Regulatory Guide, DG-4025. The guide is being issued to provide 
guidance to licensees on acceptable methods to determine the quantity 
of licensed material (i.e., radionuclides) in abnormal discharge into 
the unrestricted area through the ground water discharge pathway at 
commercial nuclear power plants. American National Standards Institute/
American Nuclear Society (ANSI/ANS)-2.17-2010 (R2016), ``Evaluation of 
Subsurface Radionuclide Transport at Commercial Nuclear Power Plants,'' 
provides such methods. The

ANSI/ANS standard does not specify the use of any specific ground water 
flow and transport model. It provides a graded, risk-informed approach 
for evaluating the effects of subsurface radionuclide transport. The 
ground water flow and transport model developed by licensees should be 
a site-specific model, based on the complexity of geologic and 
hydrologic conditions, the types of radioactive materials and facility 
design, the types and effectiveness of engineered and natural barriers, 
and the proximity to surface water and ground water receptors. A 
facility that has less significant radionuclide source term, minor 
subsurface contamination, simple or well-understood hydrogeology, or 
limited effects on ground water resources generally requires less 
extensive site characterization, mathematical modeling, and 
performance-confirmation measures than a facility with significant 
residual radioactivity that has the potential to exceed national 
radiation protection standards. The appendix to RG 4.25 provides a 
simple ground water flow and transport model that is acceptable for use 
with simple hydrogeologic conditions and geometry such as steady-state 
saturated flow in homogeneous porous sand layers.

II. Additional Information

    The DG-4025 was published in the Federal Register on December 11, 
2015 (80 FR 77028) for a 60-day public comment period. The public 
comment period closed on February 9, 2016. Public comments on DG-4025 
and the staff responses to the public comments are available under 
ADAMS under Accession No. ML16253A330.

III. Congressional Review Act

    This RG is a rule as defined in the Congressional Review Act (5 
U.S.C. 801-808). However, the Office of Management and Budget has not 
found it to be a major rule as defined in the Congressional Review Act.

IV. Backfitting and Issue Finality

    Regulatory Guide 4.25 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 RG does not constitute backfitting 
as defined in section 50.109 of title 10 of the Code of Federal 
Regulations (10 CFR) (the Backfit Rule) and is not otherwise be 
inconsistent with the issue finality provisions in 10 CFR part 52. As 
discussed in the ``Implementation'' section of this RG, the NRC has no 
current intention to impose this guide on holders of current operating 
licenses or combined licenses.
    This RG 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 part 52.
