EPA Announces Plans for PFAS Wastewater Regulations

The U.S. Environmental Protection Agency (EPA) announced the release of Effluent Guidelines Program Plan 15 (Plan 15) to protect the nation’s waterways. According to the EPA Plan 15 will follow the science and the Clean Water Act to develop technology-based pollution limits and studies on wastewater discharges from industrial sources. 

Plan 15 focuses on evaluating the extent and nature of both nutrient and per- and polyfluoroalkyl substances (PFAS) discharges. Plan 15 is part of the EPA’s PFAS Strategic Roadmap to restrict PFAS discharges from industrial sources through a multi-faceted Effluent Limitations Guidelines program. 

Plan 15 announces EPA’s determination that revised effluent limitations guidelines and pretreatment standards (ELGs) are warranted for reducing PFAS in leachate discharges from landfills. The Agency made this decision after concluding a detailed study that was discussed in Preliminary Effluent Guidelines Program Plan 15. 

The EPA also announced several new and expanded studies, including:

  • An expansion of the ongoing study of PFAS discharges from textile manufacturers;

  • A new study of publicly owned treatment works (POTW) influents to characterize the PFAS concentrations from industrial dischargers to POTWs and inform implementation of pretreatment programs to address them; and

  • A new study on concentrated animal feeding operations (CAFOs) to make an informed, reasoned decision on whether to undertake rulemaking to revise the ELGs for CAFOs.

“For 50 years, EPA has implemented the Clean Water Act to protect our nation’s waters that are essential to healthy communities. This Effluent Guidelines Program Plan represents a critical next step to tackle pollutants like PFAS and nutrients at the source, before they can harm our health and the environment,” said Assistant Administrator for Water Radhika Fox in the EPA relase. “With this action, EPA continues to demonstrate our commitment to using the best available data and treatment technologies to reduce harmful industrial pollutants.”

Merit Laboratories is a leading national PFAS environmental laboratory, analyzing drinking water, soil, wastewater, groundwater, and other sample matrices, including biosolids and sludge. Analytical methods performed by Merit for PFAS include drinking water by EPA 533, EPA 537.1, and EPA 537 rev. 1.1, biosolids by ASTM D7968-17 with Isotopic Dilution, and soil, wastewater, groundwater, and surface water by ASTM D7979-19 with Isotopic Dilution, ASTM D7968-17, and development of the new EPA 1633 method.
