The Bonneville Power Administration (BPA) is funding ongoing research on Caspian terns, double-crested cormorants, and several species of gulls (glaucous-winged, western, California, and ring-billed) begun in 1996. BPA analyzed environmental impacts of the research in an Environmental Assessment (EA) completed in 2001 (DOE/EA-1374). The purpose of this Supplement Analysis (SA) is to determine if a supplemental EA is needed to analyze additional research activities proposed as part of that project.

In 1998, the Department of Energy determined that a new facility to store highly enriched uranium materials at the Y-12 National Security Complex was needed. The new facility was intended to modernize security, improve operational efficiency, and consolidate highly enriched uranium materials. The originial design was patterned after a previously constructed facility at another Department site and consisted of a concrete bunker covered by and earthen berm on the top and three sides of the facility. In February 2000, the Department approved the berm design. The Y-12 Complex is now part of the Department's National Nuclear Security Administraton (NNSA).

For over 30 years, the Department of Energy (Department) operated geous diffusion plans in Oak Ridge, Tennessee; Portsmouth, Ohio; and Paducah, Kentucky, to meet its enriched uranium needs. As a byproduct of the enrichment process, about 704,000 metric tons of depleted uranium hexafluoride were generated and stored in approximately 58,00 cylinders at the enrichment plants. While the cylinders are currently stored with little risk to workers, the public, and the environment, they are gradually deteriorating. Prolonged storage has the potential to increase the Department's safety and health risks from handling operations, natural disasters, or malicious acts.

NOA for the EA Addendum and FONSI for Waste Disposition Activities at the Paducah Site

DOE must continue to manage (i.e., treat, store, and dispose) and control its wastes safely, efficiently, and cost effectively in compliance with applicable federal and state laws while protecting public health and the environment. The wastes considered in the assessment are limited to DOE’s ongoing and legacy non-CERCLA waste management operations at the Paducah Site. These wastes include LLW, MLLW, and TRU waste, as well as materials stored in DOE Material Storage Area (DMSAs). Also included is storage of USEC program wastes, which are characterized as one or more of these waste types. Wastes not covered in this EA are those associated with the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA) activities, including decontamination and decommissioning activities, and disposition of wastes associated with USEC operational activities. The cumulative impacts section of the EA does take these wastes into consideration.
