and 100, the discussions of static and dynamic analyses are acceptable if the stability of all safety-related facilities has been analyzed from a static and dynamic stability standpoint including bearing capacity rebound, settlement, and differential settlements under dead loads of fills and plant facilities, dynamic loads including “live” and seismic loads with consideration of loading sequences and combinations. The bearing capacity estimates must include consideration of settlements associated with the strength estimates. A discussion and evaluation of lateral earth pressures with consideration of surcharges from adjacent structures and construction equipments, and hydrostatic/dynamic ground water loads acting on plant facilities should be included. Field and laboratory test procedures and results must be included to document soil and rock properties used in the analyses. The applicant must show that the methods of analysis used are appropriate for the local soil conditions and the function of the facility. Static and dynamic analyses of the bearing capacity and settlement of the supporting soils under the loads of fills, embankments, and foundations, as well as the lateral earth pressure on the foundation and structures, are evaluated by state-of-the-art methods. In general, the evaluation procedure includes: A. Determining whether or not the soil and rock properties used in the analyses represent the actual site conditions beneath the planned locations of plant facilities. The site investigation, sampling, and laboratory test programs must be adequate for this evaluation. B. Determining whether or not the methods of analysis are appropriate for the planned earthworks, foundations, and soil conditions at the site. Dynamic properties should be distinguished from static properties, and proper input parameters should be used for static or dynamic stability analysis. C. Determining whether or not the bearing capacity, settlement, differential settlement, and
