Info

Environmental Impacts of Operation they are related to plant design features or site characteristics not found on the Monticello site are listed in Appendix F. 4.1 Cooling System Category 1 issues in Table B-1 of 10 CFR Part 51, Subpart A, Appendix B, that are applicable to the Monticello cooling system operation during the renewal term are listed in Table 4-1. Nuclear Management Company (NMC) stated in its Environmental Report (ER) (NMC 2005a) that it is not aware of any new and significant information associated with the renewal of the I Monticello operating license (OL) that would warrant additional, plant-specific analysis of the remaining applicable Category 1 issues. 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 I process, its evaluation of other available information, or public comments on the draft I Supplemental Environmental Impact Statement (SEIS). Therefore, the staff concludes that there are no impacts related to these issues beyond those discussed in the GELS. For all of these issues, the staff concluded in the GElS that the impacts are SMALL, and additional plantspecific mitigation measures are not likelyto be sufficiently beneficial to be warranted. A brief description of the staff's review and the GElS conclusions, as codified in Table B-i, for each of these issues follows: Altered current patterns at intake and discharge structures. Based on information in the GELS, the Commission found that Altered current patterns have not been found to be a problem at operating nuclear power plants and are not expected to be a problem during the license renewal term. The staff has not identified any new and significant information during the staff's I independent review of the NMC ER, the scoping process, the staff's site visit, its evaluation of other available information, or public comments on the draft SEIS. Therefore, the staff concludes that there are no impacts of altered current patterns at intake and discharge structures during the renewal term beyond those discussed in the GELS. Temperature effects on sediment transport capacity. Based on information in the GELS, the Commission found that These effects have not been found to be a problem at operating nuclear power plants and are not expected to be a problem during the license renewal term.
