Document Description
The Boeing Company and the U.S. Department of Energy revised a Closure Plan for the Hazardous Waste Management Facility (HWMF) located in Area IV of the Santa Susana Field Laboratory. The HWMF consists of two separate structures called Building 29 and Building 133. Building 29 stored alkali metal waste and/or surplus, primarily sodium and potassium. The waste alkali metals were generated from research and development projects on heat exchangers using alkali metals. The waste material and contaminated equipment were transferred to Building 133 for treatment. The materials were placed in a chamber where gas burners melted and facilitated the reaction of the alkali metals with the ambient air. Water was then sprayed in the chamber finalizing the reactions and producing caustic alkali wastewater. The wastewater was collected and shipped off-site for disposal. The HWMF has been inactive since 1997 and all hazardous waste inventory has been treated and/or removed. The Closure Plan proposes to demolish the buildings and send the debris off-site for disposal. Any contamination found under the facility will be excavated and disposed to an off-site facility. Archaeological pictorgraphs located on the Santa Susana Field Laboratory are not located in the project area. Some sensitive plant species have been identified in the project area and will be protected.
