Equipment and Structures

Equipment and structural components of the processing facility that will contact PCB containing materials, process water, or storm water, such as processing equipment machinery and related components, construction equipment, various structures, and project vehicles, will be decontaminated. Table 5-2 describes, for the materials and types of equipment and structures to be used in Phase 1, the anticipated decontamination and sampling protocols to be followed, PCB decontamination criteria, and the ultimate disposition options. The decontamination procedures include, but are not limited to, power washing of unpainted and painted metal surfaces, scarification and removal of concrete surfaces or coatings, and rinsing of processing facility containers. Disposable equipment or equipment that has contacted PCB materials and is not salvageable and solid waste residuals from decontamination operations may be placed in rail cars and disposed of in the TSCA landfill. During Phase 1 operations, the PFOC will have dedicated equipment and vehicles within the EZ. The contractor’s equipment that is used within this zone will be power washed as described in Table 5-2 before being removed from the site. Vehicles are not expected to enter and leave the EZ on a routine basis. Fuel will be transferred from a fuel vendor staged outside the Vehicle/Equipment Decon Station to equipment as well as to an on-site fuel truck dedicated to the EZ during operations. If vehicles are required to leave the EZ during operations, the Vehicle/Equipment Decon Station will be used to rinse tires and wheel wells with water. If a vehicle is observed to contain high levels of dirt or PCB-containing materials, it will be thoroughly pressure or steam-washed. Rinsate from decontamination will be collected in the storm drain system, which is routed to the on-site water treatment plant.
