The Department of Energy’s National Nuclear Security Administration (NNSA) announced that it will conduct a virtual public hearing via Zoom for the Draft Site-Wide Environmental Impact Statement (SWEIS) on Livermore Lab’s current and future operations.

This meeting is open to anyone who would like to attend from anywhere in the country. You do not need to live near Livermore or Tracy to have a valid voice and opinion about U.S. nuclear weapons development activities at the Livermore Lab.

The meeting is expected to include a presentation from the NNSA and Lab personnel as well as a public comment session where public comments will be recorded – and, under the law, must be responded to in the final review document.

The Virtual Public Hearing via Zoom:

Tuesday, December 13, 2022 from 6:00pm – 8:30pm

 The hearing is part of its public participation process under the National Environmental Policy Act for the SWEIS, which is intended to analyze the potential environmental impacts of continued operations and proposed projects at both the Livermore Lab Main Site and its Site 300 high explosives testing range over the next 15 years.

The Draft SWEIS covers a huge array of existing and proposed programs and actions at the Lab. For example, the document describes 61 proposed projects, totaling approximately 2.9 million square feet, at the Livermore Site; and 14 proposed projects, totaling approximately 385,000 square feet, at Site 300.

In addition, it proposes 20 types of modernization/upgrade/utility projects – each involving several facilities. Under the Proposed Action, NNSA would also decontaminate and demolish about 150 facilities, totaling approximately 1,170,000 square feet.

The document also details proposed operational changes that would increase the tritium emissions limits in the National Ignition Facility (Building 581) and the Tritium Facility (Building 331), decrease the administrative limit for fuels-grade-equivalent plutonium in the Superblock (Building 332), increase the administrative limits for plutonium-239 at Building 235, and revise the National Ignition Facility radioactive materials administrative limits to be consistent with the Department of Energy’s Facility Hazard Categorization Standard.
