Final Supplement Analysis (SA) and Determination on Complex Transformation Supplement Environmental Impact Statement (SPEIS) for Expanded Pit Production to be Released Later This Week

The Department of Energy’s National Nuclear Security Administration (DOE/NNSA) has approved a final Supplement Analysis (SA) and determination on the Complex Transformation Supplement Environmental Impact Statement (SPEIS) which evaluated whether increasing capabilities to produce a minimum of 50 pits per year at a re-purposed Mixed-oxide Fuel Fabrication Facility (MFFF) at the Savannah River Site (SRS) and a minimum of 30 pits per year at Los Alamos National Laboratory (LANL), with additional surge capacity at each site if needed, would require the preparation of a new or supplement EIS.  This SA is the programmatic, complex-wide analysis mentioned in the Notice of Intent for the site-specific SRS EIS that was published in the Federal Register (FR) on June 10, 2019, and the final of the draft SA that was released for an approximately 45-day public comment period on June 28, 2019.

The public comments received during that comment period were considered in the development of the Final SA and a Comment Response Document (CRD) was prepared and is attached to the SA as an Appendix.

The final SA and determination will be posted on the NNSA website and will be announced in a Notice of Availability in the Federal Register later this week.  No sooner than 30 days thereafter, the Department will publish an Amended Record of Decision (AROD) based on the Complex Transformation SPEIS and the associated final SA and determination.

DOE/NNSA is committed to meeting its obligations under the National Environmental Policy Act (NEPA) as it carries out its obligation to establish the capability to produce 80 plutonium pits per year by 2030.  This commitment involves evaluating the NEPA implications of the pit production mission Complex wide in the final SA to the Complex Transformation SPEIS.  It also involves NNSA documenting site-specific NEPA reviews, including the previously announced EIS for the proposal to re-purpose MFFF at SRS and LANL in separate documents.
