of the investigation program is based on the methods discussed in SRP Section 2.5.4. Subsection 2.5.5.4. The preliminary specifications and quality control techni- ques to be used during construction are reviewed by the staff to ascertain that all design conditions are likely to be met (Refs. 5 and 9). During this part of the review the following are among those subjects reviewed for adequacy: 1. Proposed construction dewatering plan to ensure that it will not result in damage either to the natural or engineered foundation materials or to the structural foundation. 2. The excavation plan to remove all unsuitable materials from beneath the foundations and the quality control procedures which establish suitable materials. 3. The techniques and equipment to be used in compacting foundation and embankment materials. 4. The quality control and testing program to provide a high level of assurance that: a. The selected borrow material is as good and as relatively homogeneous as anticipated from the investigation program. b. The compacted foundation soil meets design specifications. 5. The techniques for improving the stability of natural slopes such as drainage, grouting, rock bolting, and applying gunite. 6. The plans for monitoring during and after construction to detect occurrences that could detrimentally affect the facility. Such monitoring includes 2.5.5-8 Rev. 2 - July 1981 periodic examination of slopes, survey of settlement monuments, and measurements of local wells'and piezometers. IV. EVALUATION FINDINGS Upon completion of the staff's review of the geotechnical engineering aspects of the material presented by the applicant related to the stability of all earth and rock slopes, both natural and man-made, an evaluation of completeness, accuracy and adequacy is made. If the evaluation confirms that the applicant has met the requirements and regulatory positions of References 1 through 11, the conclusion in the SER states that the investigations performed for slope
