EPA Rollback Threatens Landmark Air Toxics Safeguards for Gulf Coast Communities

The Biden-era HON rule, which tightened limits on hazardous air pollutants from over 200 petrochemical plants, is being dismantled under the Trump administration through dozens of temporary exemptions and a planned rewrite. Communities in Louisiana's Cancer Alley, who fought for decades for these protections, now face renewed exposure to chemicals like benzene and ethylene oxide. All nine air toxics rules issued by the previous administration have been rescinded, revised, or reconsidered.
