Availability Notice


This supplemental environmental impact statement (SEIS) has been prepared in response to an application submitted by STP Nuclear Operating Company (STPNOC) to renew the operating licenses for South Texas Project (STP), Units 1 and 2, 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, natural gas-fired combined-cycle generation, supercritical coal-fired generation, combination alternative, purchased power, and not renewing the license (the no-action alternative).

The U.S. Nuclear Regulatory Commission staff’s (NRC’s) recommendation is that the adverse environmental impacts of license renewal for STP are not great enough to deny the option of license renewal for energy planning decisionmakers. 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 STPNOC;
  • consultation with Federal, state, local, and tribal government agencies;
  • the NRC’s environmental review; and
  • consideration of public comments received during the scoping process.
