Facility Layout

The facility consists of four 8,000 square-foot buildings (numbered 1-4 in the adjacent photo), a 1,000 square-foot hazardous waste storage structure, and an outdoor storage yard. Buildings 1, 2 and 4 and the Hazardous Waste Storage Building are dedicated to hazardous waste activities, which are regulated under RCRA, and overseen by Arizona Department of Environmental Quality (ADEQ). ADEQ has been delegated this authority by EPA.

Buildings 2, 3, and 4 currently include PCB operations, which are regulated under the Toxic Substances Control Act (TSCA) and overseen by the U.S. Environmental Protection Agency (EPA). The outdoor storage yard contains storage containers and other miscellaneous equipment or materials, including 30 cubic yard roll-off bins used to store solid equipment or parts that once contained PCBs. Materials located in the outdoor storage yard are not regulated under TSCA since they do not contain PCB at concentrations equal to or greater than 50 parts per million.

Summary of PCB Operations

PCB equipment (e.g., electrical transformers or capacitors) and materials are generally shipped to the facility by truck. The receiving buildings contain truck bays, or below-grade areas, where the truck can be staged. Once a shipment of PCB materials arrives at the facility, the manifests (or shipping papers) are reviewed for accuracy. The equipment or materials are then off-loaded from the trucks and inspected. PCBs equipment and materials are staged in designated areas within the buildings.

PCB processing is conducted as needed, and not on a regular basis. Processing involves draining PCB liquids from equipment. The emptied equipment, or carcass, is flushed, and disassembled to some extent to obtain parts that can be recovered. The carcass is then packed with absorbent material, and stored in 30 cubic yard roll-off bins in the outdoor storage yard.

Once full, the roll-off bins are transferred to an approved disposal facility. Only solids and equipment that are fully drained are allowed to be stored in the roll-off bins, however, as an extra precaution, the roll-off bins are lined with weather-resistant tarp, and remain covered when not in use.

Liquid PCBs are stored in containers (drums or totes) within the warehouse portion of the facility. A barcoding system is used to track the inventory, and ensure that the amount of PCBs at the facility does not exceed the permitted capacity. This system is used to track gallons, type of equipment, pounds, and number of drums or totes at the facility.

Containers used to store PCBs are properly labeled and stored in designated areas based on PCB concentration. The PCBs are later disposed of at the appropriate disposal facility. Copper cores and other recoverable metal parts are soaked in a decontamination solution, rinsed off, and shipped off-site for recycling.

Facility Timeline

The facility has been receiving and storing PCB waste for off-site disposal since 1991. The facility, then known as Salesco Systems USA, Inc. (Salesco), obtained a TSCA Commercial Storage Approval (permit) in 1994. Salesco operated until May 2000.

This facility has since operated under a number of different names, as shown below. Veolia is currently conducting TSCA operations under Salesco’s 1994 TSCA permit, which they are authorized to do.

Veolia Facility Timeline

The facility’s latest permit application is currently being reviewed by EPA, and a permit renewal decision has not been made. Veolia’s permit application requests an increase in their PCB storage, and also indicates that the location of PCB operations will be changed to different buildings onsite.
