Common-User Ammunition Terminal
Military Ocean Terminal Concord (MOTCO), CA, is the U.S. military’s primary West Coast common-user ammunition terminal. Under the direction of the U.S. Army’s Surface Deployment and Distribution Command, MOTCO operates two ocean terminal piers and an Army-owned rail system that connects with two major public rail lines. MOTCO’s mission is to safely and efficiently process, ship, and receive military cargo, including ordnance, to support the Pacific Command area of operation.
Located in the East San Francisco Bay region, the 6,641-acre installation encompasses a 115-acre inland area and a 6,526-acre tidal area, which includes 2,045 acres of offshore islands. The installation is the site of a 1944 explosion of two ships that were being loaded with 5,000 tons of munitions. The explosion scattered munitions and debris up to 12,000 feet away, impacting 5,000 acres on the land and in the water.
Under the Military Munitions Response Program (MMRP), Parsons is conducting environmental restoration services in a remedial investigation and feasibility study (RI/FS) at MOTCO to determine and evaluate cleanup options for military munitions and explosive debris at three previously identified munitions response sites (MRSs) resulting from the 1944 explosion and from other munitions handling and demilitarization activities.
