d 17), and whether the applicant's interpretations are supported by adequate field records in the SAR. See also Subsection 2.5.2.3. 2.5.4-7 DRAFT Rev. 3 - April 1996 Subsection 2.5.4.5. In meeting the requirements of References 1 through 7 and the regulatory positions of References 8 through 11, the presentation of the data concerning excavation, backfill, and earthwork analyses is acceptable if: 1. The sources and quantities of backfill and borrow are identified and are shown to have been adequately investigated by borings, pits, and laboratory property and strength testing (dynamic and static) and these data are included, interpreted, and summarized. 2. The extent (horizontally and vertically) of all Category I excavations, fills, and slopes are clearly shown on plot plans and profiles. 3. Compaction specifications and embankment and foundation designs are justified by field and laboratory tests and analyses to assureensure stability and reliable performance. 4. Quality control methods are discussed and the quality assurance program described and referenced. 5. Control of groundwater during excavation to preclude degradation of foundation materials is described and referenced. Subsection 2.5.4.6. In meeting the requirements of References 2, 3, 4, 6, and 7 and the regulatory positions of References 8, 10, and 11, the analysis of groundwater conditions is acceptable if the following are included in this subsection or cross-referenced to the appropriate subsections in SRP Section 2.4 of the SAR: 1. Discussion of critical cases of groundwater conditions relative to the foundation stability of the safety-related facilities of the nuclear power plant. 2. Plans for dewatering during construction. 3. Analysis and interpretation of seepage and potential piping conditions during construction. 4. Records of field and laboratory permeability tests. 5. History of groundwater fluctuations as determined by periodic monitoring of 16 local wells and piezometers. Flood conditions
