Section Contents

The following table lists those environmental issues listed in the Generic Environmental Impact Statement for License Renewal of Nuclear Plants (GEIS) (NRC 1996) and 10 CFR Part 51, Subpart A, Appendix B ,Table B-1, that are not applicable to the Oconee Nuclear Station (ONS) because of plant or site characteristics.

ISSUE--10 CFR Part 51, Subpart A, Appendix B, Table B-1 Category GEIS Sections Comment
Surface Water Quality, Hydrology, and Use (for all plants)
Altered salinity gradients 1 4.2.1.2.2

4.4.2.2

ONS cooling system does not discharge to an estuary. Lake Keowee is freshwater.
Water-use conflicts (plants with cooling ponds or cooling towers using makeup water from a small river with low flow) 2 4.3.2.1

4.4.2.1

This issue is related to heat- dissipation systems that are not installed at ONS.
Aquatic Ecology (for plants with cooling-tower-based heat-dissipation systems)
Entrainment of fish and shellfish in early life stages 1 4.3.3 This issue is related to heat- dissipation systems that are not installed at ONS.
Impingement of fish and shellfish 1 4.3.3 This issue is related to heat- dissipation systems that are not installed at ONS.
Heat shock 1 4.3.3 This issue is related to heat- dissipation systems that are not installed at ONS
Groundwater Use and Quality
Groundwater-use conflicts (potable and service water, and dewatering; plants that use >100 gpm) 2 4.8.1.1

4.8.2.1

ONS uses < 100 gpm of groundwater.
Groundwater-use conflicts (plants using cooling towers withdrawing makeup water from a small river) 2 4.8.1.3

4.4.2.1

This issue is related to heat- dissipation systems that are not installed at ONS or are operated on bodies of water that are much smaller than Lake Keowee.
Groundwater-use conflicts (Ranney wells) 2 4.8.1.4 ONS does not have or use Ranney wells.
Groundwater quality degradation (Ranney wells) 1 4.8.2.2 ONS does not have or use Ranney wells.
Groundwater quality degradation (saltwater intrusion) 1 4.8.2.1 ONS is located on Lake Keowee, a freshwater lake.
Groundwater quality degradation (cooling ponds in salt marshes) 1 4.8.3 This issue is related to a heat- dissipation system that is not installed at ONS.
Groundwater quality degradation (cooling ponds at inland sites) 2 4.8.3 This issue is related to a heat- dissipation system that is not installed at ONS.
Terrestrial Resources
Cooling tower impacts on crops and ornamental vegetation 1 4.3.4 This issue is related to a heat- dissipation system that is not installed at ONS.
Cooling tower impacts on native plants 1 4.3.5.1 This issue is related to a heat- dissipation system that is not installed at ONS.
Bird collisions with cooling towers 1 4.3.5.2 This issue is related to a heat- dissipation system that is not installed at ONS.
Cooling pond impacts on terrestrial resources 1 4.4.4 This issue is related to a heat- dissipation systems that is not installed at ONS.
