Continued Operation of Lawrence Livermore National Laboratory

DOE's National Nuclear Security Administration (NNSA) prepared this Supplement Analysis (SA; DOE/EIS-0348-SA-06) to consider potential and/or cumulative impacts of the proposed decontamination and decommissioning (D&D) projects, and to determine whether the 2005 Final Site-wide Environmental Impact Statement (SWEIS) for Continued Operation of Lawrence Livermore National Laboratory should be supplemented, a new EIS prepared, or if no further NEPA documentation is required.

Based on that review and analysis, DOE NNSA concluded that although the D&D projects would generate annual waste and truck trip levels above the 2005 SWEIS yearly estimates, total generated waste since 2005 has remained below the SWEIS projections, while overall traffic volume has decreased since 2005. The proposed project's impacts remain consistent with those analyzed in the 2005 SWEIS, and no further NEPA documentation is required.
