nable process for identifying “new and significant” information with respect to an NRC conclusion documented in the ESP EIS and should document the results of this process in an auditable form for issues for which the COL applicant does not identify “new and significant” information. The COL ER should address issues for which the COL applicant does identify “new and significant” information. Under 10 CFR 51.70(b), the NRC is required to independently evaluate and be responsible for the reliability of all information used in the EIS, including an EIS prepared for a COLA. Toward that end, the NRC staff may (1) inquire into changes to information disclosed in an ESP EIS that is referenced in a COLA and (2) identify new information that may affect the assumptions, analyses, or conclusions in the ESP EIS. If the staff determines that new information that was not submitted is significant, it may send a request to the applicant to submit the information. In the context of a COLA that references an ESP, the NRC staff defines “new” (as in “new and significant” information) as information that was (1) not generally known or publicly available during the preparation of the EIS and thus was not considered in preparing the ESP ER or EIS and (2) has become known and available since the authorization of the ESP. New information may include, but is not limited to, specific design information that was not available during the review of the ESP application (especially where the design interacts with the environment) or information that was in the ESP application but has changed by the time of the COLA submittal (e.g., a change in the regional socioeconomic profile resulting from a natural event like Hurricane Katrina). New information may or may not also be “significant.” For example, if an EIS prepared for an ESP application identifies a new threatened or endangered species located within the identified area of potential effect, the staff will treat this as
