PCBs in Caulk

The Federal Environmental Protection Agency (EPA) takes very seriously the issue of PCBs in caulk that exists in some older structures in the U.S. FERMA Corporation takes this potential hazard seriously as well, and we are always prepared to meet and exceed directives from the EPA regarding PCBs in caulk.

PCBs in Caulking is an Ongoing Issue

The EPA learned that caulk containing polychlorinated biphenyls (PCBs) was used in many structures, including schools. This occurred primarily in the 1950s through the 1970s. Most buildings constructed after 1978 do not contain cauld with PCBs. In 2009, the EPA issued guidance for building managers and school administrators to help manage PCBs in caulk and tools that can help mitigate potential exposure.

The caulking in question typically surrounds doors and windows, although it can also be found in some masonry work. It may also have been used for repair work throughout a structure. You can’t determine the presence of PCBs in this type of caulk by manufacturer, brand, or appearance.

Tolerance Levels for PCBs in Caulk

The current Federal EPA level of regulation on this caulk is for material that contains PCBs at 50 parts per million (ppm) or greater as a PCB bulk product waste. Disposal of this material is regulated under the Toxic Substance Control Act. However, some states may have enacted tighter regulations regarding its disposal and handling within their jurisdiction. It is important that your demolition contractor is clear on the presence of this PCB-containing caulk and the responsibilities under the Federal statute as well as any state regulations.

Through EPA’s Regional PQB Coordinators, the Agency will also assist communities in identifying potential problems and, if necessary, developing plans for PCB testing and removal.

The EPA continues to conduct additional research into the presence of PCBs in caulking and the potential hazard this creates. There are several unresolved scientific questions that must be better understood to assess the magnitude of the problem and identify the best long-term solutions.

For example, the link between the concentrations of PCBs in caulk and PCBS in the air or dust is not well understood. The Agency is doing research to determine the sources and levels of PCBs in schools and to evaluate different strategies to reduce exposures. The results of this research will be used to provide further guidance to schools and building owners as they develop and implement long-term solutions.

Contact FERMA Corporation if You Suspect PCBs in Your Caulking

FERMA is committed to safety first. We believe that short cuts lead to deep cuts. This includes handling and removing potentially hazardous materials. If you suspect some caulking in your building may be dated prior to 1978, call us to investigate and propose efficient solutions.
