Content:
es are evaluated by conducting an inde- pendent literature search and comparing these results with the information included in the applicant's SAR. References used in reviewing this subsection include published or unpublished reports, maps, geophysical data, construction records, etc., by the USGS, other Federal agencies, State agencies, and private companies (such as oil corporations and architect engineering firms). In conjunction with the literature search, the staff and its advisors review the J geological investigations conducted by the applicant. Using the references listed at the end of this section and other sources, the following questions -are Considered in detail: 1. Are the exploratory techniques used by the site investigator representative of the present state-of-the-art? Do the samples represent the in situ soil conditions? 2. Do the applicant's investigations provide adequate coverage of the site area and in sufficient detail to define the specific subsurface conditions with a high degree of confidence? 3. Have all areas or zones of actual or potential surface or subsurface sub- sidence, uplift or collapse, deformation, alternation, solution cavities or structural weakness, unrelieved stresses in bedrock, or rocks or soils that might be unstable because of their physical or chemical properties been identified and adequately evaluated? Subsection 2.5.4.2. Properties of underlying materials are evaluated to deter- mine whether or not the investigations performed (including laboratory and field testing) were sufficient to justify the soil and rock properties used in the foundation analyses. To determine whether sufficient investigations were performed, the staff care- fully reviews the criteria developed and used by the applicant in laying out the boring, sampling and testing program and evaluates the effectiveness of the program in defining the specific foundation conditions at the site to assure that all critical conditions have been adequately sampled
