The EPA has taken steps to weaken the 2024 chemical-plant pollution rules, including exemptions and a proposal to loosen limits on ethylene oxide, although a complete repeal was not yet final in the cited evidence.

Verified September 6, 2026Key Evidence
The 2024 EPA rule imposed stricter limits on toxic emissions from more than 200 chemical plants, including controls on ethylene oxide and chloroprene.
ProPublica reported in January 2026 that the stricter rules technically remained in effect, but the EPA had exempted dozens of chemical plants and sterilization facilities while pursuing a formal process.
In March 2026, the EPA proposed weaker limits for ethylene oxide, and later reporting described a broader plan to rescind the 2024 regulations. The available evidence supports weakening or reversal efforts, but not necessarily a completed repeal of the entire rule.

The claim is supported by developments under the Trump administration. The EPA’s 2024 rule required more than 200 chemical plants to reduce emissions of ethylene oxide and chloroprene, two carcinogenic pollutants. That rule was finalized by the Biden administration and remains the relevant pollution-control measure described in the claim.epa.govepa.govBiden-Harris Administration Finalizes Stronger Clean Air Standards for Chemical...
