The Remediation and Redevelopment (RR) Program is sending 3,038 letters to parties responsible for cleanup at open remediation sites in Wisconsin.
The letter is a reminder to those responsible parties (RPs) to consider per- and poly-fluoroalkyl substances (PFAS) or other suspected emerging contaminants (e.g. 1,4 – Dioxane) during the site investigation scoping phase of their remediation efforts, per NR 716.07 and NR 716.09. A site investigation may be considered incomplete if the RP does not consider and address all hazardous substances or environmental pollution at a known site or facility subject to ch. 292, Wis. Stats., including emerging contaminants like PFAS. Failure to do so could result in the need for additional assessment work or field work and potential closure delays.
