Site-Wide Environmental Impact Statement (SWEIS)
On February 14, 2013, the Final Site-Wide Environmental Impact Statement for the Continued Operation of the Nevada National Security Site and Off-Site Locations in the State of Nevada was published. Available electronically and in hard copy, the document can be obtained by clicking here or calling 702-295-3521.
Stakeholder and public participation played an important role in the development of the final document, to include the several hundred comments submitted. Publication of this Final SWEIS, and the subsequent Record of Decision (anticipated March-April 2013), will replace the 1996 SWEIS and two Supplement Analyses that followed.
These documents were prepared in accordance with National Environmental Policy Act (NEPA) requirements that dictate government agencies to prepare Environmental Impact Statements analyzing how activities at their respective sites may be impacting the environment. Activities are analyzed using several scenarios referred to as alternatives. The Final SWEIS explores three alternatives:
No Action Alternative
The No Action Alternative reflects the use of existing facilities and ongoing projects to maintain operations consistent with those experienced in recent years at the Nevada National Security Site (NNSS) and offsite locations in Nevada. For each of the three mission areas and their supporting programs, the level of operation for associated capabilities, projects, and activities is determined by operational levels actually realized since 1996. In other words, No Action is maintaining the status quo.
Expanded Operations Alternative
The Expanded Operations Alternative includes the activities and level of operations under the No Action Alternative, plus expansion of existing activities and capabilities or new projects at the NNSS and offsite locations in Nevada. The additional capabilities and increased level of operations would include modification and/or expansion of existing facilities and construction of new facilities and greater numbers of activities than under the No Action Alternative.
Reduced Operations Alternative
The Reduced Operations Alternative reflects diminished activity levels, as well as decommissioned facilities and areas at the NNSS and other offsite locations in Nevada. The Reduced Operations Alternative includes continued implementation of previous NEPA decisions, but may not retain all capabilities from those decisions. No new projects or facilities are proposed under the Reduced Operations Alternative. Operational levels would be reduced relative to the No Action Alternative, and geographical and organizational constraints would be placed upon some activities under the Reduced Operations Alternative.
The final step in the SWEIS regulatory process is the issuance of a Record of Decision (ROD), officially announcing the agency’s decisions to move forward. The ROD will be issued after March 22, 2013.
