Environmental Impacts of Alternatives * Environmental Justice No environmental pathways or locations have been identified that would result in disproportionately high and adverse environmental impacts on minority and low-income * populations if a replacement nuclear plant were built at the Monticello site. Some impacts on housing availability and prices during construction might occur, and this could disproportionately affect the minority and low-income populations. After completion of construction, it is possible that the ability of the local government to maintain social services could be reduced at the same time as diminished economic conditions reduce employment prospects for the minority and low-income populations. Overall, impacts are expected to be SMALL. Projected economic growth in Wright and Sherburne counties and the ability of minority and low-income populations to commute to other jobs outside the Wright County area could mitigate any adverse effects. Impacts at other sites would depend upon the site chosen and the nearby population distribution, but are likely to be SMALL to MODERATE. Impacts to minority and low income residents of Wright County associated with closure of Monticello could be significant, but could also be mitigated by projected economic growth for the area. 8.2.4.2 Once-Through Cooling System This section discusses the environmental impacts of constructing a nuclear power plant at the Monticello site using onCe-through cooling. The impacts (SMALL, MODERATE, or LARGE) of this option are the same as the impacts for a nuclear power plant using a closed-cycle system. However, there are minor environmental differences between the closed-cycle and once-through cooling systems. Table 8-6 summarizes the incremental differences. Table 8-6. Summary of a Comparison of Environmental Impacts of a New Nuclear Power Plant Sited at the Monticello Site with Once-Through Cooling Impact Category Land Use Ecology Water Use and Quality-Surface Water Water Use and Quality- Groundwater Air Quality Change in Impacts from Closed-Cycle Cooling Impacts may be less (e.g., through elimination of cooling towers) or greater (e.g., if a reservoir is required). Impacts would depend on ecology at the site. Possible impacts associated with entrainment of fish and shellfish in early life stages, impingement of fish and shellfish, and heat shock. Increased water withdrawal leading to possible water-use conflicts, thermal load higher than with closed-cycle cooling. No change. No change. NUREG-1437, Supplement 26 8-42 August 2006 1

No change. 8.2.5 Purchased Electrical Power If available, purchased power from other sources could potentially obviate the need to renew the Monticello OL. Purchased power accounted for approximately 14 percent of NSP power sales in 2004 (NSP 2004). In Canada, 62 percent of the countryrs electrical generation capacity is derived from renewable energy sources, principally hydropower (DOEIEIA 2001). Canada has plans-to continue developing hydroelectric power, but the plans generally do'not include large-scale projects (DOE/EIA 2001). Canada's nuclear generation is projected to increase by 1.7 percent by 2020, but its share of power generation in Canada is projected to decrease from 14 percent currently to 13 percent by 2020 (DOE/EIA 2001). Consequently, it is unlikely that electricity imported from Canada would be able to replace the Monticello generating capacity. The staff assumes that 100 mi of new 345-kV transmission lines on a 1 50-ft wide corridor in southern Minnesota, potentially affecting approximately 1800 ac, would be required toimport purchased power. Considering the nature of transmission line development and potential mitigation measures available, impacts of greatest concern are those related to change in land use, terrestrial ecological communities, and aesthetics. Land use and terrestrial ecological habitats in the region where it is assumed the line would be built consists predominantly of rural agricultural land interspersed in some areas with natural vegetation. Development of the transmission line would limit changes in future land uses on the corridor to those that are compatible with the line, but most agricultural practices and other currently compatible uses could continue. Establishment of a corridor for the transmission line would have little effect on either the amount or value of habitat represented by agricultural land, the predominant habitat expected on lands traversed by these facilities, because compatible agricultural practices could continue. Similarly, open wetlands would be spanned and therefore little effected. Some visual August 2006 8-43 NUREG-1 437, Supplement 26 1
