Final Draft Supplement Analysis of the 2008 Site-Wide Environmental Impact Statement for Los Alamos National Laboratory EXECUTIVE SUMMARY This supplement analysis for the 2008 “Site-Wide Environmental Impact Statement for Continued Operation of Los Alamos National Laboratory, Los Alamos, New Mexico,” (2008 SWEIS) reviews changes in operations at Los Alamos National Laboratory (LANL or the Laboratory) since the publication of the 2008 SWEIS (2008 through 2017) and evaluates the continued adequacy of the 2008 SWEIS for the future of LANL operations (2018 through 2022). The purpose of this supplement analysis is to provide a basis for understanding if there have been substantial changes in the LANL mission or operations or significant new circumstances or information relevant to environmental affects that are not bounded by the 2008 SWEIS analysis. The decision to be made by the U.S. Department of Energy (DOE) is to determine if the 2008 SWEIS is currently sufficient and will remain so through 2022, or if additional National Environmental Policy Act (NEPA) analysis and documentation (i.e., a supplemental or new SWEIS) is required. The records of decision issued by the DOE for the 2008 SWEIS approved the No Action Alternative, with a continued decision to produce up to 20 pits per year, and some specific additional projects from the Expanded Operations Alternative. The status of the projects and site operations, and their associate impacts, approved in the records of decision are reported in the SWEIS yearbooks. To date, data collected from across the Laboratory and reported in the yearbooks indicate that LANL has consistently operated within the bounds of the 2008 SWEIS. Detailed information regarding Laboratory operations and related environmental impacts is available in the yearbooks and the Laboratory’s annual site environmental reports. These documents are available in the electronic public reading room (http://eprr.lanl.gov/oppie/service). This supplement analysis compares the potential impacts of proposed projects and operations from 2018 through 2022 with the alternatives analyzed in the 2008 SWEIS and included in the subsequent records of decision. In some cases, projects or programs analyzed in the 2008 SWEIS have been undertaken in different locations at LANL for programmatic reasons; those changes are also summarized in this supplement analysis. This document includes a summary of major projects and programs including the Technical Area 55 Reinvestment Project; modifications to the Radioactive Liquid Waste Treatment Facility; decommissioning and demolition of facilities across LANL (including Technical Areas 18 and 21); and various projects that have been initiated, implemented, and/or completed since issuance of the 2008 SWEIS pursuant to a Compliance Order on Consent with the New Mexico Environment Department. Proposed projects that have been cancelled or deferred are also included. Finally, proposed projects that would be implemented through 2022 for which planning is sufficiently developed to support a meaningful NEPA evaluation are included in this supplement analysis. This supplement analysis indicates that the environmental impacts for the periods from 2008 through 2017 and those projected for 2018 through 2022 have not substantially changed from those projected for the projects and operations selected in the records of decision and 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 provides a bounding NEPA analysis for a majority of projects planned in the next 5 years. Projects that do not fall into this category will be subject to additional NEPA analyses. iii Final Draft Supplement Analysis of the 2008 Site-Wide Environmental Impact Statement for Los Alamos National Laboratory This page intentionally left blank. iv Final Draft Supplement Analysis of the 2008 Site-Wide Environmental Impact Statement for Los Alamos National Laboratory CONTENTS ACRONYMS AND TERMS ..........................................................................................................................
