EPA Takes Another Step Toward Regulation Of PFAS Air Emissions

Although not yet enforceable, the release of draft test method OTM-50 by the U.S. Environmental Protection Agency (EPA) marks another step toward the regulation of per- and polyfluoroalkyl substances (PFAS) in air emissions, as it will facilitate the gathering of data and refinement of test methods necessary to develop air emissions standards. As part of its release, EPA Assistant Administrator for Research and Development Chris Frey noted that OTM-50 is intended to apply to chemical manufacturers, industrial users of PFAS and PFAS-destruction technologies. Its applicability is likely to broaden into other industries, however, as EPA's understanding of PFAS in air emissions evolves. EPA also published a related FAQ.
