Environmental Impacts of Operation 4.5 Groundwater Use and Quality The Category 1 issue in 10 CFR Part 51, Subpart A, Appendix B, Table B-1 that is applicable to Monticello groundwater use and quality is listed in Table 4-8. NMC stated in its ER that it is not aware of any new and significant information associated with the renewal of the Monticello OL (NMC 2005a). The staff has not identified any new and significant information during its independent review of the NMC ER, the staff's site visit, the scoping process, its evaluation of I other available information, or public comments on the draft SEIS (NMC 2005a). Therefore, the staff concludes that there are no impacts related to this issue beyond that discussed in the GELS. For this issue, the GElS concluded that the impacts are SMALL, and additional plant-specific mitigation measures are not likely to be sufficiently beneficial to be warranted. A brief description of the staff's review and the GElS conclusions, as codified in Table B-i, 10 CFR Part 51, Subpart A, Appendix B, Table B-i, follows. Table 4-8. Category I Issue Applicable to Groundwater Use and Quality During the Renewal Term ISSUE-10 CFR Part 51, Subpart A, Appendix B, Table B-1 GROUND-WATER USE AND QUALITY Ground-water use conflicts (potable and servicewater; plants that use < 100 gpm) 4.8.1.1 GElS Section Ground-water use conflicts (potable and service water: plants that use < 100 gom). Based on information in the GELS, the Commission found that Plants using less than 100 gpm are not expected to cause any ground-water use conflicts. As discussed in Section 2.2.2, Monticello groundwater use is less than 100 gpm. The staff has not identified any new and significant information during its independent review of the NMC ER, the staff's site visit, the scoping process, its evaluation of other available information, or public I comments on the draft SEIS. Therefore, the staff concludes that there are no groundwater use conflicts during the renewal term beyond those discussed in the GELS. The Category 2 issue related to groundwater use and quality during the renewal term that is applicable to the Monticello site is discussed in the section that follows. This issue, which requires plant-specific analysis, is listed in Table 4-9. NUREG-1 437, Supplement 26 4-40 August 2006 1
Environmental Impacts of Operation Table 4-9. Category 2 Issue Applicable to Groundwater Use and Quality During the Renewal Term 10 CFR ISSUE-l0 CFR Part 51, Subpart A, Appendix B, GElS 51.53(c)(3)(ii) SEIS Table B-1 Section Subparagraph Section GROUND-WATER USE AND QUALITY Ground-water use conflicts (plants using cooling 4.8.1.3; A 4.5.1 towers withdrawing make-up water from a small river) 4.4.2.1 4.5.1 Groundwater Use Conflicts (Make-Up From a Small River) Groundwater use conflicts for plants that have cooling towers withdrawing makeup water from a small river is a Category 2 issue, requiring a site-specific assessment before license renewal. Surface-water withdrawals from small water bodies during low-flow conditions may result in groundwater use conflicts with nearby groundwater users. Groundwater use at Monticello is regulated by a Water Appropriations Permit with MNDNR. The permit required NMC to measure groundwater elevations during 1967 to 1994, which showed that the groundwater level is higher than river elevations (NMC 2005a). The impact of consumptive loss on nearby groundwater users is associated with the difference it could potentially cause in aquifer recharge, especially if other new groundwater or upstream surface water users begin withdrawals. However, since groundwater flows towards the Mississippi River, groundwater withdrawals would not be impacted by changes in river flow. The staff reviewed available information relative to potential groundwater-use conflicts due to consumptive loss of aquifer recharge. Based on this review, the staff concludes that the potential impacts are SMALL, and additional mitigation is not warranted. 4.6 Threatened or Endangered Species Federally threatened or endangered species are listed as e Category 2 issue in 10 CFR Part 51, Subpart A, Appendix B, Table B-I. This issue is listed in Table 4-10. This issue requires consultation with appropriate agencies to determine whether threatened or endangered species are present and whether they would be adversely affected, by continued operation of the nuclear plant during the license renewal term. The presence of threatened or endangered species in the vicinity of the Monticello site is discussed in Sections 2.2.5 and 2.2.6. On June 3, 2005, the staff contacted the FWS to request information on threatened and endangered species and the impacts of license renewal (NRC 2005a). In response, on July 13, 2005, the FWS provided additional information regarding Federally listed species that have been observed or may occur in the four-county area (Wright, Sherburne, Hennepin, and Anoka counties) that includes the Monticello site and its associated transmission lines, as well August 2006 4-41 NUREG-1437, Supplement 26 1
