Environmental Impacts of Operation as concerns that the FWS has regarding those species (FWS 2005). The staff has prepared a biological assessment (BA) documenting its review of Federally listed threatened or endangered species at the Monticello site and associated transmission lines and submitted it to the FWS for concurrence (NRC 2005d). Table 4-10. Category 2 Issue Applicable to Threatened or Endangered Species in the Vicinity of Monticello During the License Renewal Term ISSUE-i 0 CFR Part 51, 10 CFR Subpart A, Appendix B, 51.53(c)(3)(ii) Table B-1 GElS Section Subparagraph SEIS Section THREATENED OR ENDANGERED SPECIES (FOR ALL PLANTS) Threatened or endangered 4.1 E 4.6 species 4.6.1 Aquatic Species The Higgins' eye pearlymussel (Lampsilis higginsih) is the only Federally listed (endangered) aquatic species reported from the four-county area that includes the Monticello site and its associated transmission lines (FWS 2005). As discussed in Section 2.2.5, the closest Essential Habitat Areas for the.Higgins' eye pearlymussel occur in the St. Croix River (RM 811), which flows into the Mississippi River approximately 89 mi downstream from Monticello (RM 900). Also, the Higgins' eye pearlymussel is not known to occur further upstream than Pool 2 (RM 848 to RM 815) of the Mississippi River, which is mostly located downstream from the Twin.; Cities area (Kelner and Davis 2002; Hornbach 2004). Therefore, potential impacts from the operation of Monticello are too far removed to adversely affect the species. The Monticello cooling-water intake and discharge are closely monitored under the NPDES program. NPDES permit limits are reviewed on a regular basis by the Minnesota Pollution Control Agency to ensure the protection of aquatic biota, including fish species that can serve as hosts for the glochidia of the Higgins' eye pearlymussel. There are no plans to conduct refurbishment or construction activities at Monticello. Therefore, the staff has concluded that continued operation of the plant during the license renewal term will have no effect on the Higgins' eye pearlymussel. Thus, it is the staff's finding, as documented in its BA (see Appendix E), that the impacts on threatened or endangered aquatic species from an additional 20 years of operation of Monticello would be SMALL, and additional mitigation is not warranted. 4.6.2 Terrestrial Species There are two Federally listed threatened or endangered terrestrial species that have the potential to occur on or in the vicinity of the Monticello site and its associated transmission lines. These two species are discussed in Section 2.2.6. One Federally threatened species, the bald NUREG-1437, Supplement 26 4-42 August 2006 1
Environmental Impacts of Operation eagle, is known to occur on the Monticello site and on one of its associated transmission corridors. The gray wolf, also a Federally threatened species, occurs in the northern portions of Minnesota and has recovered significantly, compared with its numbers in past decades. Continued recovery and dispersal of this species into central and southern portions of Minnesota is probable. Two active bald eagle nests occur in the vicinity of the Monticello site. One nest is located on Beaver Island in the Mississippi River north-northwest of the Monticello power block; the second nest is located in a transmission tower along the Monticello-Coon Creek 345 kV line. Public access to both nest sites is limited. The nest located on Beaver island is approximately 1000 ft from the Monticello power block in which the majority of site activity occurs and would not be affected by routine site operation or maintenance activities. The nest located in the transmission tower is in a remote area and Xcel Energy has restricted right-of-way maintenance activities in the vicinity of the nest (NMC 2005b). NMC has not identified any additional construction or refurbishment activities that would result in greater land disturbance during the license renewal period (NMC 2005a). Furthermore, Xcel Energy has in place a program to install flight diverters on its transmission lines to reduce'the potential for avian collisions and has entered into a memorandum of understanding (MOU) with the FWS to develop and implement an Avian Protection Plan (Xcel Energy et al. 2002). Electrocutions in the U.S. of large raptors almost always occur on comparatively low voltage distribution lines, not transmission lines. NMC and Xcel Energy are not aware of any adverse impacts to threatened or endangered species that have resulted from the operation of the Monticello plant during its 30-year operating history (NMC 2005a). Therefore the staff concludes that operations and maintenance activities on the Monticello site or its associated transmission line corridors are not likely to adversely affect the bald eagle. The gray wolf currently does not occur on the Monticello site or associated transmission line corridors. Operations and maintenance activities at Monticello and its associated transmission corridors will have no effect on the gray wolf. Based on this information, as documented in its BA (NRC 2005d), the staff concludes that the potential impacts on threatened or endangered terrestrial species from an additional 20 years of operation of Monticello on terrestrial threatened and endangered species would be SMALL, and additional mitigation is not warranted. 4.7 Evaluation of Potential New and Significant Information on Impacts of Operations During the Renewal Term The staff has not identified new and significant information on environmental issues listed in 10 CFR Part 51, Subpart A, Appendix B, Table B-i, related to operation during the renewal term. The staff also determined that information provided during the public comment period did August 2006 4-43 NUREG-1437, Supplement 26 1
