Y-12 National Security Complex Site-Wide Environmental Impact Statement; Oak Ridge, Tennessee

The National Nuclear Security Administration (NNSA) has prepared a draft Supplement Analysis (SA) of the 2011 Final Site-Wide Environmental Impact Statement (SWEIS) for the Y-12 National Security Complex, Earthquake Accident Analysis (DOE/EIS-0387-SA-04). NNSA has prepared the draft SA to evaluate the potential impacts of an earthquake accident at Y-12, based on updated seismic hazard information. Based on this SA, NNSA will determine whether the existing 2011 Y-12 SWEIS should be supplemented, a new SWEIS is warranted, or if no further NEPA documentation is required.
