This Supplemental Environmental Impact Statement (SEIS) for Disposition of Uranium Oxide Conversion Product Generated from Conversion of DOE’s Inventory of Depleted Uranium Hexafluoride [DOE/EIS-0359-S1 and DOE/EIS-0360-S1] evaluates the environmental impacts resulting from the disposition of up to 800,000 metric tons of uranium oxide resulting from the conversion of depleted uranium hexafluoride (DUF6) at the Department’s two operating DUF6 conversion facilities in Paducah, Kentucky and Portsmouth, Ohio. 

In 2004, DOE issued two site-specific EISs, one each for specific actions in Paducah and in Portsmouth, analyzing impacts of construction, operation, maintenance, and decontamination and decommissioning of conversion facilities.  DOE issued Records of Decision in July 2004 (DOE/EIS-0359 and DOE/EIS-0360) addressing all but one action.  A decision on that action – specific off-site disposal locations for disposition of the conversion products – was deferred pending additional NEPA review.  At the time, two proposed disposal locations were considered – a Class A facility in Clive, Utah and the low-level waste facility at the Nevada Test Site.  A new potential disposal site has been identified, Waste Control Specialists’ facility in Andrews, Texas, which had not been previously analyzed. 

This SEIS assesses the impacts of off-site transportation (by both truck and rail) and disposal of uranium oxide at these three potential locations.  It also assesses a No-Action Alternative in which the uranium oxide is maintained in safe storage at the cylinder yards adjacent to the conversion facilities.
