n models used in the PSHA. Appendix C of RG 1.208 describes acceptable methods for addressing significant new information in the PSHA Literature Review. The staff proceeds with a literature search and review of relevant references (e.g., published geologic reports, USGS professional papers and open-file reports, university theses, physiographic and geologic maps, and aeromagnetic and gravity maps) to acquire additional pertinent information on regional and local geology and seismology. 2.5.1-10 Revision 5 – July 2014 However, as publication of data and results commonly lags behind completion of research projects and excavation investigations, a reviewer does not rely entirely on information submitted by the applicant or that in published literature. The reviewer identifies any pertinent studies underway in the site region and obtains information on preliminary results of these studies. Some of these studies of other data may be proprietary in nature and should be handled accordingly. The reviewer gives particular attention to models or data that have the potential to introduce alternative interpretations to the models or data in the application, which might affect conclusions for safety or suitability of the site. Development of Requests for Additional Information During the detailed technical review, staff develops requests for additional information (RAIs) related to issues considered to be inadequately addressed in the application and that might affect conclusions for safety or suitability of the site. If insufficient data are provided in the application to support interpretations and conclusions presented, the staff will request the applicant to provide additional clarifying information.

The RAIs might indicate the need to conduct additional investigations. The detailed review
