Riverbank Army Ammunition Plant

Riverbank AAP is in the northern San Joaquin Valley, 6 miles northeast of Modesto and 90 miles east of San Francisco. It includes 132 buildings, 19 from the original con-struction period, and covers 168 acres. Some acreage is currently leased to nonmilitary concerns. In 2005, however, DoD recommended to Close Riverbank AAP in its BRAC Recommendations (see below for details).

Riverbank AAP was constructed in 1942 and began operation as an aluminum reduction facility in 1943. During World War II, its annual production of aluminum, a critical component for aircraft manufacture, was 96 million pounds. The plant was closed in 1944 as requirements for aircraft declined. During the Korean War it was reopened and converted to an Army ammunition plant for the manufacture of steel car-tridge cases. It was the largest shell-casing plant at that time, operated by Norris Industries.

Construction activities and the installation of six production lines were assigned to Bechtel Corp. The site was closed again in 1958 but reopened in 1966 to produce shell and mortar casings and related metal parts for the Vietnam War. It was again operated by Norris Industries in association with Bechtel Corp. It was classified as inactive in 1981. Norris Industries is the current contractor, and the plant is in maintenance or lay-away of standby facilities. Current tenants include American Safety Products and LMC-West.

BRAC 2005

In its 2005 BRAC Recommendations, DoD recommended to close Riverbank Army Ammunition Plant, CA by relocating the artillery cartridge case metal parts functions to Rock Island Arsenal, IL. There were 4 sites within the Industrial Base producing Metal Parts. To remove excess from the Industrial Base, the closure would allow DoD to generate efficiencies and nurture partnership with multiple sources in the private sector.

The total estimated one-time cost to the Department of Defense to implement this recommendation would be $25.2M. The net of all costs and savings to the Department during the implementation period would be a cost of $10.4M. Annual recurring savings to the Department after implementation would be $6.5M with a payback expected within 3 years. The net present value of the costs and savings to the Department over 20 years would be a savings of $53.3M. Assuming no economic recovery, this recommendation could result in a maximum potential reduction of 106 jobs (89 direct jobs and 17 indirect jobs) over the 2006 - 2011 period in the Modesto, CA Metropolitan Statistical Area (less than 0.1 percent). Environmentally, continued management and/or deed restrictions at Riverbank Army Ammunition Plant would be necessary to ensure future protection of federally listed species. Restoration, monitoring/sweeps, access controls, and/or deed restrictions might be required at Riverbank Army Ammunition Plant to prevent disturbance, health and safety risks, and/or long-term release of toxins to environmental media. Riverbank Army Ammunition Plant also had a domestic wastewater treatment facility that might require cleanup. This recommendation will require spending approximately $2.5M for environmental compliance activities. Riverbank Army Ammunition Plant reported approximately $10.5M in environmental restoration costs, which DoD has a legal obligation to pay regardless of BRAC's final decision.
