public health and safety or common defense and security that might be developed following issuance of an ESP In order to verify that no geologic features or conditions exist beneath the safety-related structures at the site that could compromise plant safety, the staff proposes a permit condition requiring an applicant to: (1) perform detailed geologic mapping of the excavations for nuclear island structures; (2) examine and evaluate geologic features discovered in excavations for safety-related structures other than those for the nuclear island; and (3) notify the NRC once excavations for safety-related structures are open for inspection by NRC staff. 2. Combined License Reviews NRC staff reviews a COL application referencing a certified standard design to determine that sufficient information is presented to demonstrate that the characteristics of the site fall within the DC site parameters rule. NRC staff reviews a COL application referencing an ESP application to determine that sufficient information is presented to demonstrate that the design of the facility falls within the site characteristics and design parameters specified in the early site permit as applicable to this SRP section. In accordance with 10 CFR 52.79(b)(2), if the design of the facility does not fall within the site characteristics and design parameters, the application shall include a request for a variance from the ESP that complies with the requirements of 10 CFR 52.39 and 10 CFR 52.93. In the absence of certain circumstances, such as a compliance or adequate protection issue, 10 CFR 52.39 “Finality of early site permit determinations” precludes the staff from imposing new site characteristics, design parameters, or terms and conditions on the ESP at the COL stage. Consequently, a COL application referencing an ESP need not include a re-investigation of the site characteristics that have previously been accepted in the referenced ESP. However, long-term environmental changes and changes
