Preferred Alternative for Certain Quantities of Plutonium Evaluated in the Final Surplus Plutonium Disposition Supplemental Environmental Impact Statement

The U.S. Department of Energy/National Nuclear Security Administration (DOE/NNSA) is announcing its Preferred Alternative for the disposition of certain quantities of surplus plutonium evaluated in the Final Surplus Plutonium Disposition Supplemental Environmental Impact Statement (Final SPD Supplemental EIS) (DOE/EIS-0283-S2, April 2015). Among the potential actions considered in the Final SPD Supplemental EIS, DOE/NNSA analyzed the potential environmental impacts for the disposition of 13.1 metric tons (14.4 tons) of surplus plutonium for which a disposition path is not assigned, including 7.1 metric tons (7.8 tons) of plutonium from pits that were declared excess to national defense needs and 6 metric tons (6.6 tons) of surplus non- pit plutonium. With regard to the 6 metric tons (MT) of surplus non-pit plutonium, DOE/NNSA's Preferred Alternative is to prepare this plutonium for eventual disposal at the Waste Isolation Pilot Plant (WIPP) in Carlsbad, New Mexico, a geologic repository for disposal of Transuranic (TRU) \1\ waste generated by atomic energy defense activities. DOE/NNSA may issue a Record of Decision (ROD), containing its decision(s) for disposition of this quantity of material, no sooner than 30 days from the date of publication of this notice in the Federal Register. ---------------------------------------------------------------------------
