In 2004, DOE issued Final Environmental Impact Statements (EISs) for construction and operation of facilities to convert depleted uranium hexafluoride (DUF6) to depleted uranium (DU) oxide at DOE’s Paducah Site in Kentucky (DOE/EIS-0359) and Portsmouth Site in Ohio (DOE/EIS-0360) )and two associated Records of Decision (RODs) to build the facilities. In 2020, DOE published in the Federal Register (85 FR 23022) a Final Supplemental EIS for actions for disposition of DU Oxide conversion product generated at these sites and declared waste (DOE/EIS-0359-S1 and DOE/EIS-0360-S1).

In 2020, DOE issued a ROD for transportation and disposition of DU oxide generated from the Department’s inventory of DUF6, if declared waste.  A copy of the ROD can be found at: DOE/EIS-0359-S1 and DOE/EIS-0360-S1: Record of Decision.
