Amended Record of Decision for the Installation and Operation of a Depleted Uranium Hexafluoride Conversion Facility at the Portsmouth, Ohio Site
The Department of Energy (DOE)/National Nuclear Security Administration (NNSA) is announcing this amendment to the July 2004 Record of Decision (ROD) for the Final Environmental Impact Statement for Construction and Operation of a Depleted Uranium Hexafluoride Conversion Facility at the Portsmouth, Ohio, Site (FEIS) (DOE/EIS- 0360). In this amended ROD, DOE/NNSA is announcing its decision to implement its preferred alternative for the construction and operation of a depleted uranium hexafluoride (DUF6) conversion facility at the Portsmouth, Ohio, a DOE Office of Environmental Management (EM) site. This amended ROD addresses DOE/NNSA's intent to construct and operate a fourth process line within the conversion facility, as previously analyzed in the aforementioned FEIS.
Notice of Availability of Final Supplement Analysis of the Complex Transformation Supplemental Programmatic Environmental Impact Statement
The National Nuclear Security Administration (NNSA), a semi- autonomous agency within the United States (U.S.) Department of Energy (DOE), announces the availability of a Final Supplement Analysis (SA) of the Complex Transformation Supplemental Programmatic Environmental Impact Statement (SPEIS) (DOE/EIS-0236-SA-02). NNSA prepared the Final SA to determine whether, prior to implementing a Modified Distributed Center of Excellence (DCE) Alternative for plutonium operations to enable producing plutonium pits at a rate of no fewer than 80 pits per year by 2030, the existing Complex Transformation SPEIS should be supplemented, a new environmental impact statement be prepared, or that no further National Environmental Policy Act (NEPA) analysis is required. NNSA published the Draft Supplement Analysis of the Complex Transformation Supplemental Programmatic Environmental Impact Statement on June 28, 2019, and announced a 45-day comment period. After considering all comments received, NNSA prepared the Final SA and concluded that no further NEPA documentation at a programmatic level is required.
