te parameters in the DC EA (10 CFR 51.50(c)(2)). If a given environmental issue is not resolved at the ESP stage for instances in which sufficient environmental information was not available to permit resolution (e.g. items related to a specific reactor design, such as the impacts of the fuel cycle) or because the ESP applicant was permitted to defer the issue (e.g., benefits assessment), the COL applicant must address the issue in the COL ER. DG-1325, Page-101 For matters resolved at the DC stage, if the site characteristics for the COL fall within the site parameters in the DC EA, the NRC staff may rely on or “tier off” the DC EA and will state in the COL EIS its conclusion set forth in the EA for the DC. C.2.16 Finalizing Licensing-Basis Information OVERVIEW In 2008, the NRC staff recognized that activities such as engineering, procurement, and program development generally continue throughout and following licensing and certification reviews and that applicants for DCs, COLs, or other licenses or permits issued under 10 CFR Part 52 may need to define a point during the review process at which the licensing-basis information is considered final. This issue was discussed during public meetings held in September and November 2008 for which a discussion paper entitled “Controlling Design and Plant-Specific Changes During The Review of Licensing Applications Related to New Reactors” (Ref. 98) was provided. The NRC staff received preliminary comments from the NEI in an e-mail dated November 25, 2008 ( (Ref. 99). The NRC staff subsequently issued a proposed ISG on May 28, 2009 (Ref. 100) and final guidance (DC/COL-ISG-011, “Finalizing Licensing-Basis Information”) on November 2, 2009 (Ref. 101). This regulatory topic provides updated guidance for current and future applicants and allows the retirement of DC/COL-ISG-011. An applicant for a COL or DC may choose to finalize licensing-basis information at a point during the licensing review and then defer any
