The Department of Energy’s National Nuclear Security Administration (NNSA) is in the process of preparing a new Site-Wide Environmental Impact Statement (SWEIS) for Continued Operation of Lawrence Livermore National Laboratory. The SWEIS will analyze the potential environmental impacts of the reasonable alternatives for continuing Livermore Laboratory operations for approximately the next 15 years.

Public input on the scoping, or planning, process for the SWEIS concluded on Oct. 21. NNSA will present a draft SWEIS document for public review and comment in approximately summer 2021. The availability of the draft document and a schedule of NNSA-hosted public meetings will be announced at that time. Additional information about the SWEIS and public participation can be found on the .
