Technical Guidance for Determining the Presence of Manufactured PCB Products in Buildings and Other Structures

EPA developed this document to provide a technical guidance to assist property owners or operators, their contractors, and analytical labs in determining the presence of manufactured PCB products in buildings or other structures.

In this guidance, EPA presents a statistically-based sampling approach to potentially determine the presence of PCBs in within a building or structure. The use of manufactured PCB products containing PCBs at concentrations ≥ 50 ppm is not authorized under the Toxic Substances Control Act and the federal PCB regulations at Title 40 of the Code of Federal Regulations part 761. If manufactured PCB products containing ≥ 50 ppm PCBs are found in buildings, they must be removed and disposed of as PCB bulk product waste in accordance with 40 CFR section 761.62. Additionally, PCB-contaminated substrate in contact with manufactured PCB products containing ≥ 50 ppm PCBs may be regulated for cleanup and disposal.

Disclaimer: This document and two companion worksheets do not impose any legally binding requirements or obligations on EPA, states, or the regulated community, nor do they release any party from liability for any violation of TSCA or its implementing regulations. A property owner or operator may use the guidance provided in these materials to assess whether a building potentially contains manufactured PCB products. Discussion in this document of what users “should” or “need to” or “have to” do are not statements of legal obligation but, rather, technical instruction on how to follow the approaches described in this document. This document and two companion worksheets may not apply to a particular situation based upon the circumstances, and they do not preclude the use of other approaches.  Use of these materials does not guarantee that manufactured PCB products are not present in a building, nor does it create a defense against a violation under TSCA if that occurs.
