SS046 - Railhead Munitions Staging Area

The Railhead Munitions Staging Area is a concrete pad next to a railroad spur near the conventional munitions storage area (A Bunker). The inactive railhead was used to bring munitions to Travis AFB. These operations resulted in the deposition of metals and PAH beneath the railroad tracks and in three isolated areas surrounding the concrete pad. These compounds may be a source of potential human health and ecological risk.

Since the railroad tracks have been removed from most of the rail spur, the railhead can only be used in the future as a parking lot for trucks.  The West/Annexes/Basewide Operable Unit Soil Record of Decision selected land use and access restrictions as the final remedy for the property to ensure that it is not used for residential purposes without first addressing the contaminant residue in the soil. Adherence to land use controls (LUCs) is evaluated annually.  Additional investigation at Site SS046 was performed in 2016, and the data will be used to reassess the need to conduct additional remedial actions at this site in order to remove the LUCs.
