Facility Layout

Container Storage Area 3 in Building No. 7 is currently in a completely enclosed, roofed, steel shell building of approximately 32,000 square feet. The dimensions of Container Storage Area 3 are 80' x 400'. The floor is concrete with berms located at each personnel or vehicle exit. The secondary containment capacity of Container Storage Area 3 is 210,380 gallons.

The mid-section of Building No. 7 is currently segregated into storage/containment areas separated by masonry walls or six-inch-high curbs. The floor and bins are free from cracks and seams. Ramps lead into each containment area. The floor area in Container Storage Area 3 is overlaid with concrete a minimum of three inch thick and sloping to blind sumps. The walls defining the containment areas are reinforced concrete curbs. All concrete work is free of cracks and control joints. Construction joints between walls and slabs contain steel plate waterstops. The containment has a volume in excess of 10% of the storage volume of Container Storage Area 3 and the interior surfaces are sealed with a chemically resistant sealer.

Additionally, to provide segregation from other materials stored in Container Storage Area 3, Bay Area B has two secondary containment pallets measuring 124 1/2" x 61 5/8" x 22" each for PCB segregation/storage that have a containment capacity of 535 gallons each for a total tertiary (i.e., within Container Storage Area 3 secondary containment) containment capacity of 1,070 gallons.

Summary of PCB Operations

This facility operates as a repackaging, bulking, consolidation, transfer, and storage facility for off-site generated hazardous and nonhazardous wastes, as well as a storage facility for PCBs. The facility will handle PCBs in one storage area - Bay Area B, Container Storage Area 3. Refer to Appendix III for site diagrams. That is the only three unit onsite where PCBs are stored. The maximum quantity of regulated PCB material that will be stored at the facility at any one time will be the equivalent of ninety (90) 55-gallon drums (5,000 4,950 gallons). The total site storage of TSCA regulated PCBs will not exceed 5,000 4,950 gallons. All containers will be DOT approved, non-leaking, properly labeled containers in good condition. In the PCB storage area, containers will be placed in rows four feet wide with two-foot aisles between rows. On average, containers with a capacity equal to or greater than 30 gallons will be stacked two high, while containers with a capacity of less than 30 gallons will be stacked four high. All containers will be placed on pallets.
