The facility consists of four approximately 8,000 square-foot buildings, and an approximately 1,000 square-foot hazardous waste storage structure located north of Building 1. Building 1 and the hazardous waste storage building are dedicated to hazardous waste processing and storage activities, which are regulated under Resource Conservation and Recovery Act (RCRA) and are overseen by the Arizona Department of Environmental Quality (ADEQ). Buildings 2, 3, and 4 are where PCB activities are carried out. PCB activities are regulated under the TSCA and are overseen by the U.S. Environmental Protection Agency (EPA).
Summary of PCB Operations at Veolia
Electrical equipment containing PCBs and other PCB waste are generally shipped to the facility by truck. The receiving buildings contain truck bays, or below-grade areas, where the truck can be staged. This allows for easy loading or off-loading of equipment or materials, since the bays allow for the ground surface to be level with the truck floor. 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. The warehouse buildings where PCB containers are staged have large roll-up doors to allow for easy transfer of equipment and materials into the buildings. PCBs equipment and materials are staged in designated areas within the buildings that meet TSCA storage requirements.
PCB processing is conducted on certain types of electrical equipment containing PCB liquid. The first step in processing involves draining PCB liquids from the equipment. The emptied equipment is flushed, disassembled, and metal parts are recovered. Liquid PCBs are stored in containers in designated storage areas based on the PCB concentration of the liquid. The PCBs are later disposed off-site at the appropriate disposal facility. Recoverable metal parts are soaked in a decontamination fluid; rinsed off; tested to ensure adequate decontamination; and if below the required PCB limit (10 µg/100 cm2), shipped off-site for recycling.
