**The short version**

- The US Court of Appeals for the District of Columbia Circuit unanimously upheld the EPA’s designation of PFOA and PFOS as hazardous substances under Superfund law.
- The ruling rejects a challenge from seven industry trade groups, including the US Chamber of Commerce, which argued the EPA overstated risks and conducted a faulty cost-benefit analysis.
- The decision allows the EPA to continue holding polluters financially liable for cleanup costs associated with the two chemicals.
- No right-rated outlet covered the ruling, according to the reports below.

The US Court of Appeals for the District of Columbia Circuit upheld the Environmental Protection Agency’s decision to designate two per- and polyfluoroalkyl substances, PFOA and PFOS, as hazardous under the Superfund law. The ruling, issued on Tuesday, was unanimous and rejected a legal challenge brought by seven industry trade groups led by the US Chamber of Commerce.

The court’s decision preserves the EPA’s authority to require companies to pay for the cleanup of sites contaminated with the two chemicals. The agency designated PFOA and PFOS as hazardous substances in 2024, a move that expanded its power to hold polluters liable for remediation costs. The trade groups had argued that the EPA overstated the risks of the chemicals and failed to conduct a proper cost-benefit analysis.

The three-judge panel, which included judges Patricia Millett, Gregory Katsas, and Neomi Rao, dismissed each of the industry groups’ claims. In the written opinion, Judge Millett stated that the EPA had fairly considered the objections and reasonably rejected them based on its findings and expertise.

## What the coverage left out

No right-rated outlet ran the story, according to the reports below. None of the digests from any side mentioned the specific industries or companies most affected by the ruling, or the estimated financial impact of the designation on those sectors.

## Who covered it

Shares of the 7 covering outlets with a published leaning rating:

- Left: 43% (3)
- Centre: 57% (4)
- Right: 0% (0)

0 of 7 covering outlets carried no usable leaning rating and were excluded from those percentages. Coverage measured 2026-08-19T05:00:17.046217+00:00.

**Coverage watch:** developing. Checked 8 times; 0 checks found a material change. Most recently checked 2026-08-19T06:00:10.655Z.

## How the sides framed it

### Left

- The three left-rated reports led on the EPA’s expanded authority to hold polluters liable for cleanup costs. E&E News, the only outlet with a full report, framed the ruling as a victory for the Biden administration’s environmental policy, noting that the Trump administration had chosen to defend the rule in court. The outlet quoted Judge Patricia Millett’s opinion directly, highlighting the court’s rejection of industry arguments about risk assessment and cost-benefit analysis.
- The digests from NOTUS and Bloomberg Law both carried the unanimous nature of the ruling and the EPA’s authority to pursue polluters. NOTUS included the AP’s description of the designation as expanding the federal government’s power to hold parties liable for chemical releases.

### Centre

- The four centre-rated digests focused on the financial liability for polluters. The Hill and Michigan Live both led with the EPA’s ability to force polluters to pay for cleanup. Reuters described the ruling as keeping companies that make or transport the chemicals "on the hook" for future cleanup costs. Waste Dive noted the involvement of the National Waste & Recycling Association, which had argued the EPA overstepped its authority.
- None of the centre-rated digests mentioned the political context of the ruling, such as the Biden administration’s role or the Trump administration’s decision to defend the rule. The unanimous nature of the decision was included in Reuters’ digest but omitted by the others.

### Right

No separate framing summary.

**Provisional coverage gap:** right. The watch is not closed, so this is not yet a settled blindspot finding.

## Questions

**What does the EPA’s designation of PFOA and PFOS as hazardous substances mean?**

The designation allows the EPA to hold companies liable for cleanup costs under Superfund law. It means polluters can be forced to pay for remediating sites contaminated with the two chemicals, which are known as "forever chemicals" due to their persistence in the environment.

**Who challenged the EPA’s rule and why?**

Seven industry trade groups, led by the US Chamber of Commerce, challenged the rule. They argued the EPA overstated the risks of PFOA and PFOS and conducted a faulty cost-benefit analysis. The court rejected these claims in its unanimous ruling.

**What happens next after the court’s decision?**

The ruling upholds the EPA’s authority to enforce the designation, so the agency can continue pursuing polluters for cleanup costs. Companies that manufacture, use, or transport PFOA and PFOS remain liable for contamination under Superfund law.
