Executive Summary The Commission has adopted the following statement of purpose and need for license renewal from the GELS: The purpose and need for the proposed action (renewal of an operating license) is to provide an option that allows for power generation capability beyond the term of a current nuclear power plant operating license to meet future system generating needs, as such needs may be determined by State, utility, and, where authorized, Federal (other than NRC) decisionmakers. The evaluation criterion for the staff's environmental review, as defined in 10 CFR 51.95(c)(4) and the GELS, is to determine ... whether or not the adverse environmental impacts of license renewal are so great that preserving the option of license renewal for energy planning decisionmakers would be unreasonable. Both the statement of purpose and need and the evaluation criterion implicitly acknowledge that there are factors, in addition to license renewal, that would ultimately determine whether an existing nuclear power plant continues to operate beyond the period of the current OL. NRC regulations [10 CFR 51.95(c)(2)] contain the following statement regarding the content of SEISs prepared at the license renewal stage: The Supplemental environmental impact statement for license renewal is not required to include discussion of need for power or the economic costs and economic benefits of the proposed action or of alternatives to the proposed action except insofar as such benefits and costs are either essential for a determination regarding the inclusion of an alternative in the range of alternatives considered or relevant to mitigation. In addition, the supplemental environmental impact statement prepared at the license renewal stage need not discuss other issues not related to the environmental effects of the proposed action and the alternatives, or any aspect of the storage of spent fuel for the facility within the scope of the generic determination in § 51.23(a) ["Temporary storage of spent fuel after cessation of reactor operation-generic determination of no significant environmental impact"] and in accordance with § 51.23(b). The GElS contains the results of a systematic evaluation of the consequences of renewing an OL and operating a nuclear power plant for an additional 20 years. It evaluates 92 environmental issues using the NRC's three-level standard of significance-SMALL, MODERATE, or LARGE-developed using the Council on Environmental Quality guidelines. The following definitions of the three significance levels are set forth in footnotes to Table B-1 of 10 CFR Part 51, Subpart A, Appendix B: SMALL-Environmental effects are not detectable or are so minor that they will neither destabilize nor noticeably alter any important attribute of the resource. NUREG-1437, Supplement 26 xiv August 2006 1
MODERATE-Environmental effects are sufficient to alter noticeably, but not to destabilize, important attributes of the resource. Executive Summary LARGE-Environmental effects are clearly noticeable and are sufficient to destabilize important attributes of the resource. For 69 of the 92 issues considered in the GELS, the analysis in the GElS reached the following conclusions: (1) The environmental impacts associated with the issue have been determined to apply either to all plants or, for some issues, to plants having a specific type of cooling system or other specified plant or site characteristics. (2) A single significance level (i.e., SMALL, MODERATE, or LARGE) has been assigned to the impacts (except for collective offsite radiological impacts from the fuel cycle and from high-level waste and spent fuel disposal). (3) Mitigation of adverse impacts associated with the issue has been considered in the analysis, and it has been determined that additional plant-specific mitigation measures are not likely to be sufficiently beneficial to warrant implementation. These 69 issues were identified in the GElS as Category 1 issues; In the absence of new and significant information, the staff relied on conclusions as amplified by supporting information in the GElS for issues designated as Category I in Table B-1 of 10 CFR Part 51, Subpart A, Appendix B. Of the 23 issues that do not meet the criteria set forth above, 21 are classified as Category 2 issues requiring analysis in a plant-specific supplement to the GELS. The remaining two issues, environmental justice and chronic effects of electromagnetic fields, were not categorized. Environmental justice was not evaluated on a generic basis and must be addressed in a plant-specific supplement to the GELS. Information on the chronic effects of electromagnetic fields was not conclusive at the time the GElS was prepared. This SEIS documents the staff's consideration of all 92 environmental issues identified in the GElS. The staff considered the environmental impacts associated with alternatives to license renewal and compared the environmental impacts of license renewal and the alternatives. The alternatives to license renewal that were considered include the no-action alternative (not renewing the OL for Monticello) and alternative methods of power generation. Based on projections made by the U.S. Department of Energy's Energy Information Administration (DOE/EIA), gas- and coal-fired generation appear to be the most likely power-generation alternatives if the power from Monticello is replaced. These alternatives are evaluated assuming that the replacement power generation plant is located at either the Monticello site or some other unspecified alternate location.
