Abstract

This supplemental environmental impact statement (EIS) has been prepared in response to an application submitted by Exelon Generation Company, LLC to renew the operating license for Three Mile Island Nuclear Station, Unit 1 for an additional 20 years.

This supplemental EIS includes the preliminary analysis that evaluates the environmental impacts of the proposed action and alternatives to the proposed action. Alternatives considered include replacement power from new supercritical coal-fired generation and natural gas combined-cycle generation; energy conservation/energy efficiency; and a combination of alternatives that included natural gas combined-cycle generation, conservation/efficiency, and improvements to hydroelectric dams; and not renewing the license (the no-action alternative).

The NRC has determined that the adverse environmental impacts of license renewal for Three Mile Island Nuclear Station, Unit 1 are not so great that preserving the option of license renewal for energy-planning decisionmakers would be unreasonable. This determination is based on (1) the analysis and findings in the GELS; (2) the Environmental Report submitted by Exelon Generation; (3) consultation with Federal, Sate, and local agencies; (4) the NRC staff's own independent review; and (5) the NRC staffs consideration of public comments received during the scoping process and draft supplement EIS comment period.
