National Nuclear Security Administration July 12, 2016 – Federal Register Recent Federal Regulation Documents

The National Nuclear Security Administration (NNSA), a separately organized agency within the U.S. Department of Energy (DOE), is amending its July 20, 2011, Record of Decision for the Continued Operation of the Y-12 National Security Complex (2011 ROD) (76 FR 43319) to reflect its decision to implement a revised approach for meeting enriched uranium (EU) requirements, by upgrading existing EU processing buildings and constructing a new Uranium Processing Facility (UPF). Additionally, NNSA has decided to separate the single-structure UPF design concept into a new design consisting of multiple buildings, with each constructed to safety and security requirements appropriate to the building's function. This revised approach is a hybrid of two alternatives previously analyzed in the 2011 Final Site-Wide Environmental Impact Statement for the Y-12 National Security Complex, DOE/EIS-0387 (Y-12 SWEIS). The scope of this Amended ROD is limited to actions which have been found necessary to sustain Y-12's capability to conduct EU processing operations in a safe and secure environment. Those actions are also addressed in a Supplement Analysis (SA) (DOE/ EIS-0387-SA-01), issued by NNSA in April 2016. All other defense mission activities and non-defense mission activities conducted at Y-12 under the alternative selected for implementation in the 2011 ROD are outside the scope of this decision. As a result of preparing the SA, NNSA has determined that no further National Environmental Policy Act (NEPA) analysis is needed to support this Amended ROD.
