ly stages. However, sufficient field and laboratory data should be presented and conservatively interpreted to allow a realistic assessment of the safety of proposed slopes and supporting foundations. Detailed design investigations are usually still in progress and final design conclusions have often not been made. Most of the open items of Section 2.5 remaining at the time that the safety evaluation report (SER) input is required are in the foundation engineering and slope stability areas because actual conditions may not be revealed until excavations are opened; site visits conducted after CP or COL issuance are therefore necessary. All natural safety-related slopes are examined during at least one of the two site visits required of the staff. Because excavated slopes or embankments are not usually constructed until after a CP or COL has been granted, detailed as-built documentation of these slopes and embankments, as well as complete stability and safety analyses are necessary. 2.5.5-11 Revision 4 - May 2010 Review Procedures Specific to 10 CFR Part 52 Application Types 1. Early Site Permit Reviews Subpart A to 10 CFR Part 52 specifies the requirements and procedures applicable to the Commission=s review of an ESP application for approval of a proposed site. Information required in an ESP application includes a description of the site characteristics and design parameters of the proposed site. However, the specific locations of safety-related slopes are generally not known at the ESP stage and, therefore, SRP Chapter 2.5.5 may not be complete. The subsections within SRP Chapter 2.5.5 that are not complete in the ESP application will be reviewed in detail as part of the COL or CP review. In the absence of certain circumstances, such as a compliance or adequate protection issue, 10 CFR 52.39 precludes the staff from imposing new site characteristics, design parameters, or terms and conditions on the ESP at the COL stage. Accordingly, the reviewer should ensure that
