Polychlorinated biphenyls, or PCBs, were once widely used in electrical equipment such as transformers because of their stability, insulating properties, and resistance to fire. While these qualities made them valuable in electric pole transformer units, telephone pole transformer systems, and pad mount transformers, PCBs were later found to pose serious environmental and health risks. Today, PCBs are recognized as a hazardous waste under strict federal regulations, and their management requires specialized containment, removal, and disposal solutions. Understanding why PCBs are considered hazardous waste is crucial when dealing with leaking transformers or planning utility transformer replacement.
What are PCBs and why are they hazardous?
PCBs are a group of man-made chemical compounds once added to transformer oils to improve performance. However, their chemical stability also means they do not break down easily in the environment. When released through a transformer oil leak, PCBs can persist for decades, contaminating soil, water, and air. They can accumulate in plants and animals, moving up the food chain and posing risks to human health. Studies have linked PCB exposure to immune system suppression, reproductive problems, and cancer. Because of these dangers, the Environmental Protection Agency classifies PCBs as hazardous waste, and any equipment containing PCB oils must be handled with extreme care.
PCBs in transformers
Older transformers, especially those installed before regulations restricted PCB use, may still contain PCB oils. These include units on a transformer utility pole, pad mount transformer systems, and other types of distribution equipment. When these transformers begin to deteriorate, the risk of a power pole transformer leak or pad mount transformer leak increases, making proper containment and removal essential. Once PCB oil begins leaking, it requires immediate intervention to prevent widespread contamination.
PCB Transformer Removal And Environmental Compliance
Disposing of PCB-containing equipment requires strict adherence to environmental standards. The process of PCB transformer removal involves identifying the presence of PCB oils, securely containing the transformer, and transporting it to an approved disposal or decontamination facility. ABG Bag Inc provides certified containment products that allow transformers to be safely lifted, sealed, and transported in compliance with UN, DOT, TSCA, and EPA regulations.

Why PCB waste is heavily regulated
Because PCBs are toxic and persistent, even small releases can have long-term environmental consequences. For this reason, federal and state regulations outline specific methods for transformer oil removal, containment, and transport. Failure to comply with these standards can result in fines and liabilities. Regulations also dictate how PCB oils and equipment are stored, labeled, and ultimately destroyed or decontaminated. By treating PCBs as hazardous waste, these rules are designed to protect communities and ecosystems from lasting damage.
Identifying leaking PCB transformers
It is not always obvious when a transformer is releasing PCB oil. Some signs to watch for include:
-
Dark, oily stains on the casing of an electric pole transformer
-
Wet patches or contaminated soil near a transformer utility pole
-
Visible drips on a telephone pole transformer
-
Pools of liquid beneath a pad mount transformer
Addressing these issues early reduces the risk of environmental damage. ABG Bag Inc provides helpful resources like the Guide To Identifying And Managing Leaking Utility Transformers to assist with early detection and planning.
Safe transformer oil removal
When leaks are identified, transformer oil removal must be performed carefully using approved equipment. For PCB oils, this step is particularly sensitive, as improper handling can lead to further contamination. ABG Bag Inc manufactures containment products that enable safe transformer oil removal and prevent spills during storage and transport. By using compliant containment systems, organizations ensure that both workers and the environment remain protected.
The role of containment in PCB disposal
Containment products are a vital part of managing PCB transformers safely. Without the right tools, PCB transformer removal becomes risky and difficult to execute in compliance with regulations. ABG Bag Inc’s containment solutions are designed to fully enclose leaking transformers, capture any remaining oil, and allow for safe lifting and transport. These products are recyclable, reusable, and engineered to meet the highest safety standards, making them an essential part of handling PCB hazardous waste.
Utility transformer replacement after PCB disposal
Once a PCB transformer is safely removed and disposed of, utility transformer replacement is typically necessary to restore reliable service. Modern transformers no longer use PCBs and instead rely on mineral or biodegradable synthetic oils. These newer options are safer and more environmentally friendly. ABG Bag Inc’s containment products support the safe removal of older transformers and the secure installation of replacement units, ensuring that transitions happen smoothly and responsibly.
Managing non-PCB transformer leaks
While PCB oils present the highest risks, even non-PCB oils from leaking transformers can create contamination problems. An electric pole transformer or pad mount transformer leak may still release oils into the environment that require containment and cleanup. ABG Bag Inc offers containment berms, FlexTrays, and transformer containment bags to manage both PCB and non-PCB transformer oil leaks safely.
