Federal Court Just Confirmed: PFAS Liability Isn't Going Anywhere for Waste Companies

On August 18, the U.S. Court of Appeals for the D.C. Circuit denied every petition challenging the EPA's rule designating PFOA and PFOS as hazardous substances under CERCLA. The National Waste & Recycling Association, the U.S. Chamber of Commerce, and several other industry groups had spent two years arguing the agency overstepped its authority. A three-judge panel disagreed on every count.

That decision matters more to this industry than almost anyone outside it realizes. PFOA and PFOS, two of the so-called forever chemicals, show up routinely in ordinary trash, biosolids, and landfill leachate. Nobody at a landfill, transfer station, or MRF manufactured these compounds. But CERCLA doesn't care about intent. It imposes strict, joint, and several liability on parties connected to a contaminated site, and as of August 18, waste companies have officially run out of legal runway to argue their way out of that exposure.

What actually changed on August 18. The ruling itself doesn't alter the designation, which has been in effect since July 2024. What it does is close off the industry's primary legal challenge. NWRA and the Chamber argued EPA didn't allow adequate time for public comment and relied on a flawed cost-benefit analysis. The court rejected both claims, holding that CERCLA only requires a substance to pose a "possibility" of substantial danger, not certainty, and that EPA's cost estimates fell within a reasonable range. The designation stands, and it's not going anywhere without an act of Congress or a reversal at the Supreme Court.

The "passive receiver" problem is still unresolved. NWRA's core argument all along has been that landfills, MRFs, and haulers are "passive receivers." They didn't put PFAS into commerce, they just end up handling the waste stream everyone else created. EPA has said in policy guidance that it doesn't intend to pursue enforcement against certain passive receivers, including publicly owned landfills and treatment works. But that's enforcement discretion, not law. It isn't binding on future administrations, doesn't cover private landfills or MRFs outright, and states that incorporate CERCLA's hazardous substance list into their own superfund statutes aren't bound by it at all. NWRA President Michael Hoffman called the decision disappointing and said the association will keep pushing for protections that put responsibility on whoever actually introduced PFAS into commerce.

Reporting obligations are already live, not theoretical. Any release of one pound or more of PFOA or PFOS within a 24-hour period triggers immediate reporting to the National Response Center, along with state, tribal, and local emergency planning bodies. For a facility managing leachate or wastewater discharge, that's not a distant compliance deadline. It's a standing operational requirement right now.

Congress might act, but don't build a plan around it. NWRA has been asking Congress for a CERCLA carve-out for passive receivers since at least 2022. A proposed amendment to the fiscal year 2027 National Defense Authorization Act from Sen. Pete Ricketts would exempt "resource management entities," including solid waste facilities, from PFAS-related CERCLA liability. Similar bills have surfaced before and gone nowhere. A petition for Supreme Court review is also possible given the ruling's national scope, but that's a multi-year process at best.

So what does a hauler, landfill operator, or MRF actually do with this? A few things worth acting on now, not after a demand letter shows up:

• Audit your PFAS exposure. Know which sites in your operation have historically accepted materials that could carry PFOA or PFOS, including biosolids and industrial waste streams.

• Revisit insurance and contract language. Check environmental coverage for PFAS-specific exclusions, and review indemnification terms in any transactional agreements, especially site acquisitions.

• Watch state-level rules closely. Several states incorporate the federal hazardous substance list directly into their own superfund laws, which means EPA's enforcement discretion offers you no protection at the state level.

• Keep your paper trail airtight. If a site ever becomes the subject of a CERCLA response action, the first thing regulators and plaintiffs' attorneys ask for is a record of what came in, from whom, and when.

That last point is where a lot of operators are more exposed than they realize. Paper scale tickets and manual load logs make it slow and expensive to reconstruct exactly what a facility accepted and from which generator, right when that documentation matters most. Digitizing dump tickets and scale records isn't a PFAS-specific fix, but it does turn "we think we know what came through here" into an actual, searchable audit trail. If that's a gap in your operation, Bond4Waste's dump ticket OCR software is built to close it.

Bottom line: The D.C. Circuit just confirmed that CERCLA liability for PFOA and PFOS isn't a temporary regulatory scare. It's the operating environment now, and it applies whether or not your facility ever manufactured a single ounce of the stuff. Waiting on Congress or the Supreme Court to fix the passive receiver problem is a bet, not a strategy. The operators who come out ahead will be the ones who can prove, with clean records, exactly what moved through their gates.
