Recent interim guidance from the U.S. EPA provides details for disposingof or destroying certain per- and polyfluoroalkyl (PFAS) substances and materials containing them, but the agency and industry analysts say there are lingering questions to answer before moving forward with any possible regulations.
The document, the first such federal guidance on the destruction or disposal of PFAS or PFAS-containing materials, describes the available science used in three major techniques: deep well injection, landfilling and thermal treatment. Acknowledging uncertainty about potential environmental effects, the EPA proposed the interim storage of PFAS-containing waste until further research can “reduce the uncertainties associated with other options.”
Industry groups such as the National Waste & Recycling Association (NWRA) and the Solid Waste Association of North America (SWANA) said they are still analyzing the document and discussing with their members what the interim guidance may mean for daily operations. The trade groups will likely submit comments on the document by the Feb. 22 deadline.
