EPA rollback threatens air toxics protections for Gulf Coast communities
The Biden administration's 2024 HON rule aimed to reduce hazardous air pollutants from petrochemical plants. The Trump administration has granted exemptions to over 70 facilities and plans to rewrite the rule, likely weakening protections. Community activists like Tish Taylor feel validated by the original rule but now see it being dismantled.
The 2024 rule mandated upgraded pollution controls and fenceline monitoring for six hazardous chemicals at over 200 facilities. These compounds include ethylene oxide and chloroprene, which are linked to serious health issues like leukemia and reproductive problems.
Since the change in administration, more than 70 plants have received temporary exemptions, and a formal rewrite is slated for autumn. The affected region, particularly St. John the Baptist Parish, faces cancer risks nearly fifty times the national average, with Black residents bearing a disproportionate burden.
The rollback could significantly increase exposure to carcinogenic air toxics for Gulf Coast communities, potentially elevating long-term cancer risks and other health problems. Residents in predominantly Black areas may bear the heaviest burden, as weakened monitoring and control requirements could allow higher emissions. This shift may also undermine broader regulatory momentum for industrial air toxics, affecting public health outcomes across the region for decades.
