Summary and Conclusions 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. These .alternatives were evaluated assuming that the replacement power generation plant is located at either the Monticello site (nuclear generation) or some other unspecified greenfield location. 9.1 Environmental Impacts of the Proposed Action - License Renewal NMC and the staff have established independent processes for identifying and evaluating the significance of any new information on the environmental impacts of license renewal. Neither NMC nor the staff has identified information that is both new and significant related to Category 1 issues that would call into question the conclusions in the GELS. Similarly, neither the scoping process, NMC, nor the staff has identified any new issue applicable to Monticello that has a significant environmental impact. Therefore, the staff relies upon the conclusions of the GElS for all Category 1 issues that are applicable to Monticello. NMC's license renewal application presents an analysis of the Category 2 issues that are applicable to Monticello, as well as environmental justice and chronic effects from electromagnetic fields. The staff has reviewed the NMC analysis for each issue and has conducted an independent review of each issue. Three Category 2 issues are not applicable because they are related to plant design features or site characteristics not found I at Monticello. Four Category 2 issues are not discussed in this SEIS because they are specifically related to refurbishment. NMC has stated that its evaluation of structures and components, as required by 10 CFR 54.21, did not identify any major plant refurbishment activities or modifications as necessary to support the continued operation of Monticello for the license renewal period. In addition, any replacement of components or additional inspection activities are within the bounds of normal plant component replacement and, therefore, are not expected to affect the environment outside of the bounds of the plant operations evaluated in the Final Environmental Statement Related to Operation of Monticello Nuclear Generating Plant (AEC 1972). Fourteen Category 2 issues related to operational impacts and postulated accidents during the renewal term, as well as environmental justice and chronic effects of electromagnetic fields, are discussed in detail in this draft SEIS. Five of the Category 2 issues and environmental justice apply to both refurbishment and to operation during the renewal term and are only discussed in this draft SEIS in relation to operation during the renewal term. For all 14 Category 2 issues and environmental justice, the staff concludes that the potential environmental effects are of SMALL significance in the context of the standards set forth in the GELS. In addition, the staff determined that appropriate Federal health agencies have NUREG-1 437, Supplement 26 9-4 August 2006 1
Summary and Conclusions not reached a consensus on the existence of chronic adverse effects from electromagnetic fields. Therefore, no further evaluation of this issue is required. For severe accident mitigation alternatives (SAMAs), the staff concludes that a reasonable, comprehensive effort was made to identify and evaluate SAMAs. Based on its review of the SAMAs for Monticello, and the plant improvements already made, the staff concludes that one of the candidate SAMAs is potentially cost-beneficial. However, this SAMA does not relate to adequately managing the effects of aging during the period of extended operation. Therefore, it does not need to be implemented as part of license renewal pursuant to 10 CFR Part 54. Mitigation measures were considered for each Category 2 issue. Current measures to mitigate the environmental impacts of plant operation were found to be adequate, and no additional mitigation measures were deemed sufficiently beneficial to be warranted. The following sections discuss unavoidable adverse impacts, irreversible or irretrievable commitments of resources, and the relationship between local short-term use of the environment and long-term productivity. 9.1.1 Unavoidable Adverse Impacts An environmental review conducted at the license renewal Stage differs from the review conducted in support of a construction permit because the plant is in existence at the license renewal stage and has operated for a number of years. As a result, adverse impacts associated with the initial construction have been avoided, have been mitigated, or have already occurred. The environmental impacts to be evaluated for license renewal are those associated with refurbishment and continued operation during the renewal term. The adverse impacts of continued operation identified are considered to be of SMALL significance, and none warrants implementation of additional mitigation measures. The adverse impacts of likely alternatives if Monticello ceases operation at or before the expiration of the current OL will not be smaller than those associated with continued operation of this unit, and they may be greater for some impact categories in some locations. 9.1.2 Irreversible or Irretrievable Resource Commitments The commitment of resources related to construction and operation of Monticello during the current license period was made when the plant was built. The resource commitments to be; considered in this SEIS are associated with continued operation of the plant for an additional,20 years. These resources include materials and equipment required for plant maintenance and operation, the nuclear fuel used by the reactors, and ultimately, permanent offsite storage space for the spent fuel assemblies.
