Title: Vandenberg AFB Site 23 (Landfills) FocuseD Feasibility Study
Description: The project is for the Department of Toxic Substances Control's (DTSC's) approval of a Focused Feasibility Study (FFS) plan to excavate and dispose of ~213 cubic yard of soil and sediment from 3 hot spot sub-areas of Site 23 (Landfill No. 5) at the Vandenberg Air Force Base (VAFB). This project will be performed in accordance with the FFS prepared for the U.S. Air Force by Tetra Tech, Inc., April 2008, which is incorporated by reference. The results of theRI, Ecological Risk Assessment (ERS) Addendum, and the Background Metal Sampling Technical Memorandum, which are incorporated by reference, identified chemicals of concern (COCs) present in the soil and sediment of Site 23. The COCs have demonstrated a risk to on-site workers due to exposure to polychlorinated biphenyls (PCBs) in soil at one sample location and significant risks to ecological receptors due to metals, pesticides, and PCBs in soil and sediment at the site.
