For new information to be “significant,” it should be material to the issue being considered (i.e., it has the potential to affect the finding or conclusions of the NRC staff’s evaluation of the issue.) The COL applicant only needs to provide information about a previously resolved environmental issue if it is both new and significant. The COL applicant should have a reasonable and auditable process to identify “new and significant” information, as required by 10 CFR 51.50(c)(1)(iv),and should describe the process in the ER. This process description should include (1) the methods that the COL applicant uses to ensure that it identifies new information if it exists and (2) the process used for evaluating the significance of such new information. Methods used to ensure identification of new information include the following: a. reviewing environmental monitoring results; DG-1325, Page-100 b. reviewing related scientific literature; c. conferring with environmental professionals familiar with the site environs (e.g., environmental and operations staff of a nearby nuclear or industrial facility); d. exchanging information within the industry through peer groups and industry organizations; e. consulting with subject matter experts knowledgeable of the local environment; f. consulting with Federal, State, Tribal, and local environmental, natural resource, permitting, and land use agencies; g. verifying that the assumptions and representations made in the ESP ER are still valid; h. verifying that the NRC staff’s assumptions documented in the ESP EIS are still valid; and i. reviewing information needed to perform
