Continued Operation of the Los Alamos National Laboratory, New Mexico
The National Nuclear Security Administration (NNSA), a semi-autonomous agency within the Department of Energy (DOE), announces the availability of the Draft Site-Wide Environmental Impact Statement for Continued Operation of the Los Alamos National Laboratory (Draft LANL SWEIS) (DOE/EIS-0552) in compliance with the National Environmental Policy Act of 1969.
This Draft LANL SWEIS analyzes three alternatives: (1) No-Action, (2) Modernized Operations, and (3) Expanded Operations. Under the No-Action Alternative, NNSA would continue current facility operations throughout LANL in support of assigned missions. The No-Action Alternative activities have previously completed NEPA reviews and include construction of new facilities; modernization, upgrade, and utility projects; and decontamination, decommissioning, and demolition (DD&D) of excess and aging facilities.
