will deteriorate with time and will not be suitable for undisturbed testing. However, they may be used as a visual record of the foundation material. Similarly, rock cores subject to slaking and rapid weathering, such as shale, will also deteriorate. Photographs of soil samples and rock cores, with field and final logs of all borings, should be preserved for a permanent record. DG-1392, Page 24 The site investigations should be included in the overall quality assurance program for plant design and construction according to the guidance in RG 1.28, “Quality Assurance Program Criteria (Design and Construction)” (Ref. 29), and the requirements of Appendix B, “Quality Assurance Criteria for Nuclear Power Plants and Fuel Reprocessing Plants,” to 10 CFR Part 50. Therefore, field operations and records preservation should be conducted in accordance with quality assurance principles and procedures. DG-1392, Page 25 D. IMPLEMENTATION The NRC staff may use this regulatory guide as a reference in its regulatory processes, such as licensing, inspection, or enforcement. However, the NRC staff does not intend to use the guidance in this regulatory guide to support NRC staff actions in a manner that would constitute backfitting as that term is defined in 10 CFR 50.109, “Backfitting,” and as described in NRC Management Directive 8.4, “Management of Backfitting, Forward Fitting, Issue Finality, and Information Requests,” (Ref. 30), nor does the NRC staff intend to use the guidance to affect the issue finality of an approval under 10 CFR Part 52, “Licenses, Certifications, and Approvals for Nuclear Power Plants.” The staff also does not intend to use the guidance to support NRC staff actions in a manner that constitutes forward fitting as that term is defined and described in Management Directive 8.4. If a licensee believes that the NRC is using this regulatory guide in a manner inconsistent with the discussion in this Implementation section, then the licensee may
