Availability Notice


This supplemental environmental impact statement has been prepared in response to an application submitted by Union Electric Company, a subsidiary of Ameren Corporation and doing business as Ameren Missouri (Ameren) to renew the operating license for Callaway Plant, Unit 1 (Callaway), for an additional 20 years.

This supplemental environmental impact statement includes the analysis that evaluates the environmental impacts of the proposed action and alternatives to the proposed action. Alternatives considered include replacement power from new natural-gas-fired combined-cycle (NGCC) generation; new supercritical pulverized coal-fired generation; new nuclear generation; a combination alternative that includes NGCC generation, wind power, and energy efficiency; and not renewing the license (the no-action alternative).

The U.S. Nuclear Regulatory Commission's (NRC's) recommendation is that the adverse environmental impacts of license renewal for Callaway are not great enough to deny the option of license renewal for energy planning decisionmakers. This recommendation is based on the following:

  • (a) the analysis and findings in NUREG–1437, Volumes 1 and 2, Generic Environmental Impact Statement for License Renewal of Nuclear Plants;
  • (b) the environmental report (ER) submitted by Ameren;
  • (c) consultation with Federal, state, and local agencies; and
  • (d) the NRC's environmental review and consideration of public comments received during the reviewing process.
