Availability Notice


This supplemental environmental impact statement (SEIS) has been prepared in response to an application submitted by Exelon Generation Company, LLC (Exelon), to renew the operating license for Byron Station, Units 1 and 2 (Byron), for an additional 20 years.

This SEIS includes the analysis that evaluates the environmental impacts of the proposed action and alternatives to the proposed action. Alternatives considered include: new nuclear generation, coal-integrated gasification combined cycle (IGCC), natural gas combined-cycle (NGCC), combination (NGCC, wind, and solar generation), replacement power, and no renewal of the license (the no-action alternative).

The U.S. Nuclear Regulatory Commission (NRC) staff’s recommendation is that the adverse environmental impacts of license renewal for Byron are not so great that preserving the option of license renewal for energy-planning decisionmakers would be unreasonable. This recommendation is based on the following:

  • the analysis and findings in NUREG–1437, Volumes 1 and 2, Generic Environmental Impact Statement for License Renewal of Nuclear Plants;
  • the Environmental Report submitted by Exelon;
  • consultation with Federal, state, local, and tribal government agencies;
  • the NRC's environmental review; and
  • consideration of public comments received during the scoping process and received on the draft SEIS.
