Two federal PFAS wastewater rules have moved at very different speeds this year, and metal finishers just lost more of the runway they thought they had.

Both rules trace back to the same 2021 decision. In its Effluent Guidelines Program Plan 15, EPA determined that revised discharge limits were warranted for two industrial categories. One covers manufacturers of PFAS under the Organic Chemicals, Plastics and Synthetic Fibers, or OCPSF, program, and the other covers chromium electroplating facilities under the Metal Finishing program. Five years later, one of those rules is close to a public proposal. The other has been pushed back twice.

OCPSF's PFAS-Manufacturer Rule Has Cleared White House Review

EPA's July 3 2026 Unified Agenda set a July 2026 target for proposing PFAS discharge limits on OCPSF facilities that manufacture PFAS, following an advance notice EPA issued back in March 2021. The July target came and went, but the rule kept moving. By late summer, the proposal had reached the Office of Information and Regulatory Affairs for the White House review that typically precedes Federal Register publication, with trade press reporting a possible September release. As of early September, industry trackers still listed the rule as pending rather than published, so the exact release date remains unconfirmed.

Once proposed, the rule would set the first federal PFAS-specific effluent limits for any industrial category, covering facilities that produce PFAS compounds through processes such as electrochemical fluorination. A public comment period would follow, and EPA has not said when it expects a final rule.

Metal Finishers Face a Rule Now Targeted for February 2027

The Metal Finishing rule tells a different story. EPA's own December 2024 preliminary plan targeted spring 2026 for a proposed rule addressing PFAS in chromium electroplating wastewater. The spring 2026 date slipped once, to July 2026. The July 3 Unified Agenda now lists February 2027 as the expected date for the proposal. 

The underlying science is not in question. EPA's 2021 fact sheet found that PFAS-based mist and fume suppressants, used to control hexavalent chromium during plating, anodizing, etching and chromate conversion coating, are the reason chrome finishing facilities discharge PFAS. EPA also identified facilities that had already reduced their PFAS discharges using existing treatment methods, evidence the agency has cited as support for a technology-based limit. What has moved is the calendar, not the underlying finding.

The Gap Between the Two Rules Is a Planning Signal, Not a Reprieve

Facilities that paused capital decisions to wait for a federal number, rather than continuing to evaluate suppressant alternatives and treatment upgrades on their own timeline, are now a year further from certainty than the December 2024 plan implied.

State and local requirements have not slipped alongside the federal timeline. Publicly owned treatment works still set their own pretreatment limits, and facilities discharging to a POTW can face local PFAS restrictions well before a federal chrome-finishing rule exists. Manufacturers with plating and coating operations already manage that kind of exposure across water, waste and reporting obligations at once. A federal rule with no compliance deadline attached does not reduce a facility's exposure under the permits and local ordinances that already apply.

Litigation risk also has not moved on EPA's schedule. The U.S. Court of Appeals for the Ninth Circuit ruled in Yurok Tribe v. EPA that the agency failed to adequately justify exclusions for wastewater discharges, recyclable materials, solid waste disposal, and sewage sludge under the decaBDE rule. The court remanded the rule back to the EPA for rework without vacating it, keeping current restrictions active while requiring the agency to issue more comprehensive regulations.

The broader PFAS effluent program remains a priority EPA keeps restating even as individual dates move. Administrator Lee Zeldin has said the agency intends to pursue effluent limits for PFAS manufacturers and metal finishers in some form. That language predates the current slippage and has not changed since, consistent with the agency's broader effluent guidelines work across chemical manufacturers, metal finishers and textile producers.

Two dates are worth putting on a compliance calendar now. The EPA OCPSF proposal for PFAS manufacturers has faced ongoing administrative updates on the Unified Agenda. Additionally, the EPA Metal Finishing proposal is officially expected in February 2027, with a technical basis tied strictly to chromium finishing processes firmly established by the agency.
