Impacts to minority and low-income population as a whole. residents of Wright County Some impacts on housing associated with closure of may occur during construction. Monticello could be significant, but could also be mitigated by projected economic growth for the area. Siting a replacement nuclear plant at Monticello would have a MODERATE ecological impact that would be greater than renewal of the Monticello OL. At an alternate site, there would be construction impacts and new incremental operational impacts. Even assuming siting at a previously disturbed area, the impacts would alter the ecology. Impacts could include wildlife habitat loss, reduced productivity, habitat fragmentation, and a local reduction in biological diversity. Use of cooling makeup water from a nearby surface water body could have adverse aquatic resource impacts. Construction and maintenance of the transmission line, if needed, would also have ecological impacts. Overall, the ecological impacts of a replacement nuclear plant at an alternate site could range from MODERATE to LARGE. Water Use and Quality-Surface Water The replacement nuclear plant alternative at the Monticello site is assumed to use the existing circulating water system, which would minimize incremental water-use and quality impacts. Surface-water impacts are expected to remain SMALL; the impacts would be sufficiently minor that they would not noticeably alter any important attribute of the resource. Cooling towers would likely be used at an alternate site. For an alternate site, the impact on the surface water would depend on the volume of water needed for makeup water, the discharge volume, and the characteristics of the receiving body of water. Intake from and discharge to any surface body of water would be regulated the Minnesota Department of Natural Resources (MNDNR). The impacts would be SMALL to MODERATE. NUREG-1 437, Supplement 26 8-38 August 2006 1
Environmental Impacts of Alternatives * Water Use and Quality-Groundwater The staff assumed that a new nuclear power plant located at Monticello would obtain potable, process, and fire-protection water from onsite wells similar to the current practice for Monticello (see Section 2.2.2). NMC operates five groundwater wells to meet the domestic water needs of the Monticello site. It is unlikely that groundwater use for an alternative nuclear power plant at Monticello would be significantly different than existing use at Monticello. Any groundwater withdrawal would require a permit from the local permitting authority. Overall, the impacts of the nuclear alternative at the Monticello site would be SMALL. The impacts of the nuclear alternative at an alternate site would be SMALL to MODERATE. * Air Quality Construction of a new nuclear plant at Monticello or an alternate site would result in fugitive emissions during the construction process. Exhaust emissions would also come from vehicles and motorized equipment used during the construction process. These emissions are not regulated. An operating nuclear plant would have minor air emissions associated with diesel generators and other minor intermittent sources. These minor operating emissions for a plant sited in Minnesota would be regulated by the MPCA. Overall, emissions and associated impacts at either the Monticello site or an alternate site are considered SMALL. * Waste The waste impacts associated with operation of a nuclear power plant are set out in Table B-1 of 10 CFR Part 51, Subpart A, Appendix B. Construction-related debris would be generated during construction activities and removed to an appropriate disposal site. Overall, waste impacts of a new nuclear plant at either the Monticello site or an alternate site are considered SMALL. * Human Health Human health impacts for an operating nuclear power plant are set out in 10 CFR Part 51, Subpart A, Appendix B, Table B-1. Overall, human health impacts of a new nuclear plant at either the Monticello site or an alternate site are considered SMALL. * Socloeconomics The construction period and the peak work force associated with construction of a new nuclear power plant are currently unquantified (NRC 1996). In the absence of quantitative data, staff assumed a construction period of 6 years and a peak work force of 2500. The staff assumed that construction would take place while the existing nuclear unit continues operation and would be completed by the time Monticello permanently ceases operations. During construction, the communities surrounding the Monticello site would experience demands on housing and public August 2006 8-39 NUREG-1437, Supplement 26
