17 Groups Urge EPA to Reject Chemours PFAS for Datacenter Cooling

Summary
Formal comments from 17 environmental groups asked the EPA to deny Chemours’ fast-tracked Opteon 2P50, arguing the PFAS coolant for datacenters would pose unreasonable health and climate risks.
Earthjustice said Chemours downplayed toxicity with flawed science, including rat data less sensitive to PFAS than humans, missing toxicology information and a worker exposure limit developed by the industry-linked Tera group.
Chemours countered that two-phase cooling systems are closed-loop and have low fugitive emissions, but advocates said leaks and end-of-life disposal still release f-gas that can form TFA, which Europe this month classified as hazardous.
Opteon 2P50 is the first chemical seeking expedited review under Trump’s order prioritizing datacenter chemicals, setting up a potential legal test over whether faster review can override EPA duties under toxic-substances law.
