Amended Record of Decision for the Direct-Feed Low-Activity Waste Approach at the Hanford Site, Washington
This is an amendment to the U.S. Department of Energy'(DOE) 2013 Record of Decision (ROD) for the Final Tank Closure and Waste Management Environmental Impact Statement for the Hanford Site, Richland, Washington (DOE/EIS-0391, December 2012) (TC&WM EIS) published in the Federal Register on December 13, 2013. In the TC&WM EIS, DOE analyzed 11 alternatives for the retrieval, treatment, storage, and disposal of tank wastes, followed by the closure of the single-shell waste storage tanks (SSTs) at the Hanford Site. The six other alternatives analyzed in the TC&WM EIS concerned waste management and Fast Flux Test Facility decommissioning, which are not the subject of this ROD. DOE prepared a supplement analysis (DOE/EIS-0391-SA-02; SA) which evaluated the Direct-Feed Low-Activity Waste (DFLAW) approach to operations of the Waste Treatment and Immobilization Plant (WTP), which would pre-treat and send low-activity waste (LAW) from the tank farms to the LAW Facility. This amended ROD addresses those portions of the DFLAW functions and facilities that were not addressed by the 2013 TC&WM EIS ROD.
