Abstract : As delegated by Executive Order 12580, the U.S. Department of the Army is responsible for determining response actions, consistent with the National Contingency Plan, necessary for the abatement of contamination resulting from releases of hazardous substances at Army installations. The U.S. Army Installation Restoration Program (IRP) was designed to serve as the Army's response authority. A portion of Hamilton Army Airfield (HAA) has been recommended for closure by the Commission on Base Realignment and Closure. To support Department of Army decisions regarding the property closure, the U.S. Army Environmental Center (USAEC, formerly the U.S. Army Toxic and Hazardous Materials Agency USATHAMA) is responsible for implementing environmental studies prior to property transfer. Engineering-Science, Inc., was awarded a contract to conduct an Environmental Investigation and Alternatives Assessment (EI/AA) for the base realignment and closure (BRAC) property at HAA. This document provides the results of the alternatives assessment for areas of the HAA BRAC property that were studied in the El. In July 1993, the San Francisco Bay Regional Water Quality Control Board (SFRWQCB) conditionally approved the Final EI Report (Engineering-Science 1993) contingent upon additional sampling to complete characterization of contamination at HAA (Nusrala 1993). In fulfillment of these requirements, a scope of additional environmental sampling approved by the SFRWQCB (Gregg 1994) was completed in April 1994 by the Corps of Engineers (Corps 1994). The lead regulatory agencies are now the California Environmental Protection Agency Department of Toxic Substances Control (DTSC) and the SFRWQCB.
