The U.S. Department of Energy/National Nuclear Security Administration Sandia Field Office is preparing a new site-wide environmental impact statement for continuing operations at Sandia National Laboratories in New Mexico. The new SWEIS will replace the existing 1999 Sandia/New Mexico SWEIS (DOE/EIS-0281). Its purpose is to analyze the potential environmental impacts associated with continuing current Sandia/New Mexico operations and foreseeable new and/or modified operations and facilities for approximately the next 15 years.

Public participation, including the submittal of comments, is important to the development of the SWEIS. Opportunities for public involvement are available throughout the process, and this section will be updated with information on how you can participate.


The Draft and Final Sandia/New Mexico SWEIS documents will also be available for review in the Information Repository located at the Zimmerman Library on the University of New Mexico campus. Information is also available from the NNSA NEPA Reading Room and the DOE Office of NEPA Policy and Compliance.

Public Scoping: April 21 – June 5, 2023

The purpose of scoping is to encourage public involvement and to solicit public comments on the proposed scope of the SWEIS, which helps identify the range of reasonable alternatives and the environmental issues to be analyzed.

How to Submit Comments

The public scoping period begins on April 21, 2023 and runs through June 5, 2023. Comments on the scope should be submitted verbally or in writing at the public meetings listed below. In addition, written comments can be submitted by U.S. mail or email to the addresses listed below.

By U.S. mail to:

Attn: SNL/NM SWEIS Comments
National Nuclear Security Administration,
Sandia Field Office
PO Box 5400
Albuquerque, New Mexico 87185
By email to:

Please mark envelopes and emails as: SNL/NM SWEIS Comments.

DOE/NNSA will consider comments submitted through the last day of the scoping period. Late comments will be considered as practicable based on resources and schedule. Both oral and written comments will be considered and given equal weight by DOE/NNSA regardless of how submitted.

Before including your address, email address, or other personal identifying information in your comment, please be advised that your entire comment—including your personal identifying information (excluding telephone numbers)—may be made publicly available. If you wish for DOE/NNSA to withhold your name and/or other personally identifiable information, please state this prominently at the beginning of your comment.
