Wisconsin’s Voluntary Party Liability Exemption (VPLE) program allows a person to clean up a property and receive an exemption from future liability for historic contamination. Once cleanup is complete, the VPLE Certificate of Completion (COC) provides liability protection for the owner of the property. It is also transferrable to future owners. Since 1995, the DNR has issued 186 COCs. Eighty-three voluntary parties are currently pursuing a VPLE COC.
Recent concerns over emerging contaminants, particularly per- and polyfluoroalkyl substances (“PFAS”) chemicals in Wisconsin and nationally have prompted the DNR to evaluate the potential for historical discharges of PFAS and other emerging contaminants at properties enrolled in the VPLE program that are pursuing a COC.
