Summary

  • Earthjustice’s August 26 federal lawsuit argues that the EPA’s consent orders for two photoacid generator chemicals violate the Toxic Substances Control Act, because the agency’s own findings document “acute lethality,” cancer, eye corrosion, and reproductive harm as risks the agency lacked sufficient data to quantify.
  • The EPA approved both compounds for immediate import and use while acknowledging “insufficient information on hazard,” with restrictions limited to container size but not import volume.
  • The same consent orders that document severe potential health risks also authorize the chemicals’ use, treating documented uncertainty as permission rather than prohibition.
  • Industry documents reviewed by The Guardian state that finding safer alternatives is “impossible in some instances” — a claim that converts a regulatory question into a technological constraint, but rests on industry self-attestation rather than independent alternatives assessment.

What the agency’s own documents say

The consent orders reviewed by The Guardian are the central evidence in the case. They list “acute toxicity, genetic toxicity, skin and respiratory irritation, eye corrosion, skin photosensitization, and systemic, reproductive, and developmental toxicity effects as potential risks to workers.” For the general population, the agency identified “acute toxicity, genetic toxicity, and systemic, reproductive, and developmental effects as potential risks … if exposed via drinking water, ingestion of groundwater impacted by landfill leachate, and/or inhalation from stack air releases.” Among worker risks, the orders also name “acute lethality” — sudden death — which the agency states it had “insufficient data” to assess. For each endpoint, the consent orders record that “the risks for these endpoints were not quantified due to insufficient information on hazard.”

What the approval permits

The same consent orders approve both compounds for immediate import and use. The restrictions imposed are procedural: limits on the size of the container in which a chemical can be imported, but not on the volume that can be imported. Earthjustice attorney Jonathan Kalmuss-Katz said the volume gap means the formal restriction does not constrain cumulative exposure. The consent orders also recommend incineration as the disposal pathway, while noting that the process “does not fully destroy many chemicals” and “would create unknown health risks for largely low-income communities around incinerators.” No enforceable zero-discharge standard is attached to the approval.

Where the statute meets the approval

The Toxic Substances Control Act requires the EPA to “prohibit or limit the manufacture, processing, distribution in commerce, use, or disposal of such substance or to prohibit or limit any combination of such activities to the extent necessary to protect against an unreasonable risk.” Earthjustice’s argument, in plain terms, is that the agency’s own admissions of severe potential risk and insufficient data are sufficient to establish “unreasonable risk” under that statute — and that the consent-order mechanism the agency used is the wrong tool for the finding the agency made.

Kalmuss-Katz’s framing: “This is turning the new chemical review process on its head. You have a situation where the EPA has failed at its most fundamental obligation when it comes to new chemicals, and that is to protect the public from unreasonable risk.” He added: “EPA found that both chemicals pose potentially severe risks to public health, admitted that it lacked the information needed to calculate those risks, and still approved both chemicals for immediate use.”

What the structure permits

A relationship map of the approval surfaces two features that travel together. First, the same agency documents both the harm and the permission — a pattern in which documented uncertainty is treated as permission rather than prohibition. Second, the container-size import limit is a procedural gesture that satisfies formal review without constraining exposure quantity.

A root cause analysis of the case points to the consent-order mechanism itself. Under TSCA §5(e), the EPA can grant conditional market entry following an unreasonable-risk finding, attaching restrictions rather than requiring quantified hazard first. EPA’s own regulatory framework treats insufficient information about a chemical’s hazard as a trigger for §5(e) action rather than for prohibition. The structural question is whether the consent-order pathway — as currently used — is compatible with the statute’s “unreasonable risk” mandate when the agency cannot quantify the risk it acknowledges. Whether a late-2025 executive order aimed at speeding datacenter-chemical approvals directly applied to these two compounds is obscured by redactions in the consent orders; the order itself is confirmed by reporting, the specific application is not.

The mechanism does not depend on any individual acting badly. It is the statutory path for conditional entry, applied in a way that the litigant contends is inconsistent with the underlying mandate.

Why “no substitutes” is the industry’s frame

Industry documents reviewed by The Guardian in 2024 stated that finding safer alternatives to photoacid generators is “impossible in some instances” and would require “stepping back decades in technological advancement.” PFAS compounds more broadly are essential in semiconductor manufacturing, used in as many as 1,000 process steps at the nanometric scale, according to those documents. The framing converts a regulatory question — should these chemicals be approved? — into a technological constraint — there is no other choice. The constraint, however, rests on industry self-attestation rather than an independent alternatives assessment. Redactions in the consent orders also prevent external verification of which compounds are at issue and whether they are PFAS.

The downstream exposure gap

The exposure picture does not stop at the fabrication plant. Testing data from 2022 at one U.S. fab, previously reviewed by The Guardian, showed as much as 78,000 parts per trillion of PFAS in wastewater from some samples. The EPA’s drinking-water limit for several common PFAS compounds is 4 parts per trillion — a roughly 19,500-fold gap between documented wastewater concentration and the threshold the agency itself sets for tap water. The comparison crosses matrices (one fab’s discharge samples versus enforceable drinking-water MCLs), but the magnitude still places documented industry discharge orders of magnitude outside the agency’s own tap-water threshold. The consent orders’ recommended disposal pathway, incineration, adds a second endpoint: communities near incinerators, the lawsuit and consent orders note, would bear the unknown health risk of chemicals that the destruction process does not fully eliminate. The mechanism that produced the upstream gap is replicated at the downstream endpoint.

Who carries the risk, who holds the data

A stakeholder map of the case shows a power asymmetry typical of chemical-review disputes, with one structural twist: the parties with the most information about the chemicals are also the least identifiable. The chemical manufacturer is unnamed in the redacted consent orders, as is confirmation of whether the two compounds are PFAS. The agency holds the approval power; the producer holds the data; and neither has produced the data that TSCA’s review framework would normally require. TSCA §14, the statute’s confidentiality provision, is the legal mechanism under which submitter identity and chemical identity are typically withheld from public disclosure in consent-order records.

The parties who bear the documented exposure — fab workers, fenceline communities around fabs and incinerators, downstream water users, and (per the agency’s own listing of developmental-toxicity endpoints) pregnant people and children — are the parties with the least access to either the data or the decision. Kalmuss-Katz said the agency is putting “the pursuit of AI and increased computing capacity over its obligation to protect public health and the environment,” and that environmental groups are not calling for the elimination of domestic chip production but for it to be done “in a way that isn’t exposing workers and communities to these unstudied risks.”

Lenny Siegel, executive director of the Center for Public Environmental Oversight, stated: “The EPA should not approve any new photoacid generators, even on a temporary basis, until there is enforceable assurance that there will be zero discharge of such chemicals.”

What happens next

The August 26 lawsuit is filed but undecided. Federal court litigation under TSCA §5 will resolve the specific consent orders at issue, but the structural question — whether the consent-order mechanism as currently used is compatible with the statute’s “unreasonable risk” mandate — survives any single ruling. The litigation outcome feeds back to the EPA only via a future consent-order revision, which is outside this story’s timeline.

Open questions the source leaves unresolved

  1. Is the chemical manufacturer named in the unredacted consent order, and do the compounds meet the technical definition of PFAS?
  2. Has the late-2025 executive order been applied to these specific compounds, or only to datacenter permitting more generally?
