ion and Backfill. In meeting the requirements of 10 CFR Part 50, the presentation of the data concerning excavation, backfill, and earthwork analyses is acceptable if: A. 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. B. The extent (horizontally and vertically) of all Category I excavations, fills, and slopes are clearly shown on plot plans and profiles. C. Compaction specifications and embankment and foundation designs are justified by field and laboratory tests and analyses to ensure stability and reliable performance. D. The impact of compaction methods are incorporated into the structural design of the plant facilities. 2.5.4-9 Revision 4 - May 2010 E. Quality control methods are discussed and the quality assurance program described and referenced. F. Control of groundwater during excavation to preclude degradation of foundation materials and properties is described and referenced. Excavations, backfill, and earthwork are evaluated by the staff as follows: A. The investigations for borrow material, including boring and test pit logs, and compaction test data are reviewed and judged as to their adequacy. B. Laboratory dynamic and static records of tests performed on samples compacted to the design specifications are reviewed to ascertain that state-of-the-art criteria are met. C. Analyses and interpretations are reviewed to ensure that static and dynamic stability requirements are met. D. Excavation and compaction specifications and quality control procedures are reviewed to ascertain conformance to state-of-the-art conservative standards. 6. 2.5.4.6 - Ground Water Conditions. In meeting the requirements of 10 CFR Parts 50 and 100, the analysis of groundwater conditions is acceptable if the following are included in this subsection or cross-referenced to
