STP Nuclear Operating Company, South Texas Project, Units 1 and 2

The U.S. Nuclear Regulatory Commission (NRC) is issuing for public comment a draft environmental assessment (EA) prepared under the National Environmental Policy Act of 1969 (NEPA) and NRC regulations. This EA summarizes the results of the NRC staff's environmental review, which evaluates the potential environmental impacts of issuing license amendments and granting regulatory exemptions in response to a request from STP Nuclear Operating Company (STPNOC, the licensee) for Facility Operating License Nos. NPF-76 and NPF-80, for South Texas Project (STP), Units 1 and 2, respectively. The license amendments and regulatory exemptions would allow STPNOC to make changes to the STP licensing basis to incorporate the use of both a deterministic and a risk-informed approach to address safety issues discussed in Generic Safety Issue (GSI)-191 and to close Generic Letter (GL) 2004-02.
