Interim Removal Action, Wetlands Sediment
NOE - Notice of Exemption
The Navy will excavate inside Site 5, in a 0.24 acres area identified as the Area of Ecological Concern (AOEC) to six (6) feet below ground surface to remove and dispose 2,700 cubic yards of contaminated sediment. AOEC will then be backfilled and reconstituted back to native salt marsh habitat for wildlife. The Department of toxic Substances Control (DTSC), together with Regional water Quality Control Board (RWQCB) and Department of Fish and Game (DFG), have concurred with the proposed approach for this project. The Navy will conduct this interim removal action under the Action Memorandum Non-Time-Critical Removal Action IRP Site 5, Wetlands Sediment to eliminate/minimize potential ecological risks to birds such as the song sparrow and light-footed clapper rail (a special-status species), and small mammals such as the deer mouse. This removal action is conducted pursuant to the Comprehensive Response Compensation, and Liability Act (CERCLA).
