US plants that manufacture per- and polyfluoroalkyl substances (PFAS) will soon have to control their releases of these “forever chemicals” in wastewater, the US Environmental Protection Agency says.
Currently, the EPA has no limits for PFAS in industrial wastewater discharged to public sewage treatment plants or directly into rivers, lakes, and other surface waters.
Valued for their toughness as well as their grease and water resistance in a wide variety of applications, PFAS are synthetic chemicals that are highly resistant to breaking down in the environment. Some PFAS are linked to developmental problems, cancer, and other adverse health issues.
Environmental advocates have called for the EPA to set legally enforceable, federal discharge standards for PFAS under the Clean Water Act. Meanwhile, water utilities have become increasingly concerned that the EPA will set health-based limits on PFAS allowed in drinking water—leaving them and their customers stuck with the costs of removing the pollutants while industrial releases remain unregulated.
“For the first time, EPA is committing to limit PFAS in wastewater discharges,” the EPA’s assistant administrator for the Office of Water, Radhika Fox, said in announcing the plans Sept. 8.
The agency will establish limits for these chemicals in wastewater released from PFAS producers in the organic chemical, plastics, and synthetic fiber industries. In addition, the EPA says it will set similar discharge limits for chromium electroplating facilities that use and release PFAS.
Rep. Chris Pappas (D-NH), who cosponsored PFAS control legislation (H.R. 2467) passed by the House of Representatives in July, is calling for the agency to do more.
“The EPA should expand these regulations to other known industries that are actively discharging these forever chemicals,” Pappas says in a statement.
PFAS manufacturers have time to prepare for the planned discharge limits. Generally, it takes the EPA 3 years or more to craft and finalize regulations.
The American Chemistry Council, a chemical industry association that represents US PFAS makers, had not responded to a request for comment on the EPA’s planned discharge standards by C&EN’s deadline.
