DOE/EIS-0547-S1: Scoping Materials (February 2025)

Summary

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 SEIS would continue ongoing operations at the LLNL Superblock and would add several new actions to support the enhanced Pu facility utilization.

Public Comment Opportunities

NNSA invited Federal and state agencies, Native American Tribes, state and local governments and agencies, industry, other organizations, and members of the public to submit comments to assist in identifying environmental issues and determining the appropriate scope of the LLNL SEIS through March 3, 2025. Comments received or postmarked after the comment period will be considered to the extent practicable. 

NNSA held a virtual public scoping meeting to present information and receive formal public comments on the proposed action on January 29, 2025. The scoping meeting presentation is attached below.
