Notice of Intent To Prepare a Programmatic Environmental Impact Statement for Plutonium Pit Production
The National Nuclear Security Administration (NNSA), a semi- autonomous agency within the United States (U.S.) Department of Energy (DOE), announces its intent to initiate a National Environmental Policy Act of 1969 (NEPA) programmatic environmental impact statement (PEIS) process to ensure NEPA compliance for the production of plutonium pits in support of NNSA's Stockpile Stewardship and Management Program. The PEIS will evaluate the programmatic environmental impacts of producing pits at the Congressionally mandated rate (and potentially other reasonable rates) using various single site and multi-site alternatives; associated activities at other NNSA sites; and associated waste management and transportation activities. The purpose of this Notice is to invite public participation in the PEIS process and to solicit public comment on the scope, environmental issues, and alternatives for consideration by NNSA in the draft PEIS.

Notice of Intent To Prepare a Supplemental Environmental Impact Statement for Enhanced Plutonium Facility Utilization at Lawrence Livermore National Laboratory in Livermore, California
The National Nuclear Security Administration (NNSA), a semi- autonomous agency within the United States (U.S.) Department of Energy (DOE), announces its intent to prepare a Supplemental Environmental Impact Statement (SEIS) for Enhanced Plutonium Facility Utilization at Lawrence Livermore National Laboratory (LLNL or Laboratory) in Livermore, California (DOE/EIS-0547-S1), tiered from the 2023 LLNL Site-Wide Environmental Impact Statement (SWEIS) (2023 LLNL SWEIS)(DOE/ EIS-0547). The Record of Decision (ROD) for the 2023 LLNL SWEIS was published on February 20, 2024. The ROD implemented the Proposed Action Alternative in the SWEIS and is the baseline for this SEIS. NNSA will prepare the SEIS and will analyze the potential environmental impacts of enhanced plutonium facility utilization, other reasonable alternatives that may be identified, and the baseline operations as discussed in the 2023 LLNL SWEIS. The purpose of this Notice is to invite public participation in the SEIS process and to encourage public involvement on the scope, any environmental issues, and alternatives that NNSA should consider in the draft SEIS.
