Document Description
Area 514 is the former waste treatment complex, located in the southeast portion of the LLNL site. Hazardous waste treatment and storage units previously located in this area have been replaced by, or are being moved to, the new Building 695 Decontamination Waste Treatment Facility. Units within this area operated under Interim Status and their closure activities were not included in the site wide hazardous waste facility permit. Closure activities include the removal of any remaining waste from Area 514, decontamination of equipment and buildings, disposal of a portion of the processing equipment, and the removal of structures from the area. Sampling activities will be conducted to verify that decontamination efforts were successful, determine the appropriate disposal of waste to be shipped offsite, and determine whether subsurface contamination needs to be removed to achieve the closure standard. The project may also include removal of up to 3,000 cy of contaminated soil within the top ten feet of soil, if necessary to achieve the closure standards.
Waste and debris will be either treated on-site or shipped off-site for disposal. Hazardous wastes generated will either be shipped to authorized off-site hazardous waste facilities, using uniform hazardous waste manifests, or treated in an on-site hazardous waste management facility. With respect to potential radioactive materials, Area 514 will be cleaned up to levels consistent with LLNL protocol under U.S. Department of Energy standards. Waste that is above-background radioactivity levels will be shipped to an appropriately authorized/licensed off-site low level radioactive waste facility, such as the Nevada Test Site.
