As summarized in the Environmental Management Guide for Educational Facilities (2017, Published by APPA and CSHEMA), EPA banned the commercial production of polychlorinated biphenyls (PCBs) in 1979, citing health and environmental concerns. PCBs have been identified as probable human carcinogens and cause a variety of non-cancer health effects as well.2 Due to their inherent properties including nonflammability, chemical stability and electrical insulating, PCBs were used in hundreds of industrial and commercial applications including:
Again from the aforementioned Guide book one can expect to encounter PCBs in the following:
PCBs are not regulated as a hazardous waste but instead are regulated through a specific federal law known as the Toxic Substances Control Act (TSCA). Understanding the regulatory standards of TSCA can be difficult and assistance is available from Environmental Quality Management Department (EQM) but three distinct occurrences of PCBs at UK are described further below.

The most common example of PCB containing equipment are fluorescent light ballasts, though as mentioned above there is other equipment that may be encountered. EPA has produced a PCBs in Fluorescent Light Ballasts Fact Sheet that summarizes many of the important issues surrounding the management of such equipment. Additionally, provided below is a summary of the different PCB management scenarios at UK involving light ballasts
Manufactured PCB products are materials that were made with PCBs and are in a non-liquid state. EPA has produced a PCBs in Building Materials Fact Sheet that addresses PCB products that may be found throughout some buildings or on some structures. An example of PCB containing materials that have been encountered on buildings and structures at UK is caulking used around windows and within expansion joints. Whether its caulk or some other building material that has the possibility of containing PCBs, before any building maintenance, demolition or other activities that may disturb the suspect materials are undertaken you should contact EQM for assistance and possible confirmatory sampling and analysis. There is no visual standard for determining the presence of PCBs so only laboratory analysis can provide a confirmatory determination If PCBs are determined to be present there are regulatory requirements that must be addressed.
If I have questions, what should I do?

The cutting-edge research on-going at UK necessitates that a wide variety of chemicals may be used on any given day of operation. Some of these chemicals may be comprised in their entirety or in part of PCBs. The management of PCB containing chemicals as waste should follow the same procedures as explained in Waste Pick-Up Requests (E-Trax). While PCBs themselves are not regulated as a hazardous waste their use in research often results in the generation of a mixed waste containing both PCBs and other chemicals that are regulated as hazardous and, therefore, the hazardous waste regulatory labeling and management requirements as explained in Hazardous Waste Management Basics would apply.
