Clearing Contaminants

Navigating the Complex Cleanup Requirements of PCBs

Although discussions about emerging contaminants have taken much of the focus from polychlorinated biphenyls (PCB), they still exist in electrical equipment and older construction materials, such as caulks and paints. In 1978, the U.S. Environmental Protection Agency (EPA) prohibited most applications, but some uses continue.

A prevalent misconception is that PCB concentrations below 50 parts per million collected from discharges (EPA’s acceptable level for authorized use) do not necessitate federal coordination. However, various factors—the date of discharge, the source material’s concentrations, and the distinction between authorized and unauthorized uses—must be considered to accurately understand the regulatory framework needed to manage impacts.

Langan’s team of PCB experts is frequently called upon to tackle complex PCB issues and guide clients through federal and state regulatory programs. Recently, the team improved another consultant’s efforts to remediate PCB levels on a site, reducing levels from 50 parts per million to less than one part per million. Working with the property owner who acquired a former industrial site where building structures had been demolished and debris was redistributed, Langan delineated and addressed the remaining PCB impacts, reducing them to less than one part per million—the acceptable cleanup level according to the Toxic Substances Control Act. By collaborating with the state and federal regulatory agencies, Langan also negotiated a reduced sampling frequency. The team provided significant cost savings and successfully closed the site by incorporating proposed features as engineering controls.

When PCB issues arise, it’s important for the property owner to engage a consultant who is familiar with regulations and understands the amount of work required. Building an experienced, collaborative team is key to remediating a contaminated site and avoiding inadequate characterization and disposal practices, which could lead to discharges, fines, or increased liabilities.
