Draft Supplemental EIS for Enhanced Plutonium Facility Utilization at Lawrence Livermore National Laboratory

Draft Supplemental EIS for Enhanced Plutonium Facility Utilization at Lawrence Livermore National Laboratory

In 2023, Department of Energy/National Nuclear Security Administration (DOE/NNSA) completed a Site-wide Environmental Impact Statement (SWEIS) for Continued Operation of Lawrence Livermore National Laboratory (LLNL) that analyzed the potential environmental impacts of the reasonable alternatives for continuing LLNL operations for approximately the next 15 years. The Record of Decision for the 2023 LLNL SWEIS was issued on February 20, 2024. NNSA proposes an Enhanced Plutonium Facility Utilization project in Livermore, California. This project would increase the amount of fissile materials for research and development operations at the Plutonium Facility, which would require increasing the facility Security Category (CAT) from Security CAT III operations to Security CAT II. NNSA originally identified the need for this project late in the 2023 LLNL SWEIS process, after the public comment period in May 2023, but did not have enough information to analyze the potential environmental impacts to incorporate it into the 2023 LLNL SWEIS. Since then, more studies were done on the project, and NNSA now has the information needed to perform a full, comprehensive, and robust environmental analysis by preparing this Supplemental Environmental Impact Statement (SEIS).
