NNSA Los Alamos Field Office Completes Analysis Of Sitewide Environmental Impact Statement

NNSA News:

The National Nuclear Security Administration’s Los Alamos Field Office has completed and posted a Supplement Analysis for the 2008 “Site-Wide Environmental Impact Statement for Continued Operation of Los Alamos National Laboratory, Los Alamos, New Mexico” (SWEIS).

The document provides an analysis of changes in operations at the Los Alamos National Laboratory (LANL) since the publication of the 2008 SWEIS, which covered the period from 2008 through 2017.

It also evaluates the continued adequacy of the 2008 SWEIS for the future of LANL operations from 2018 through 2022.

The supplement analysis indicates that the environmental impacts at LANL for the periods from 2008 through 2017 and those projected for 2018 through 2022 have not substantially changed from projections for the projects and operations selected in the records of decision. These impacts do not differ significantly from the impacts analyzed in the 2008 SWEIS.

Based on this analysis, additional supplementation of the 2008 SWEIS or a new SWEIS is not required at this time, and the 2008 SWEIS will provide a bounding NEPA analysis for a majority of the projects planned in the next five years. Projects that do not fall into this category will be subject to additional NEPA analyses.

This announcement is not related to NNSA’s ongoing review of the plutonium pit mission. Should NNSA determine that LANL is the preferred alternative for that work, a separate determination regarding a NEPA analysis for the necessary facilities would be needed.
