May 12, 2026 — The Trump administration is proposing to roll back a 2024 EPA rule tightening limits on ethylene oxide (EtO), a widely used medical sterilant now considered about 60× more carcinogenic than estimates used in 2006. The Biden-era rule would have required roughly a 90% reduction in emissions from dozens of facilities, using continuous monitoring and stricter controls to reduce exposure for about 2.3 million people, many in low-income communities.

The rollback would rescind those stricter standards, allowing continued releases of roughly 8 tons of EtO annually, while saving industry an estimated $47 million per year. Public health advocates argue this increases cancer risk and undermines updated science on toxicity, especially since EtO is linked to leukemia and other cancers and is released near residential areas around sterilization plants.

A central dispute is legal: whether the Clean Air Act allows the EPA to repeatedly update hazardous pollutant standards as new science emerges. The Trump EPA argues its authority is limited after the initial review, while critics say this interpretation would significantly weaken the agency’s power to tighten protections. Environmental groups, including the NRDC, are suing, framing the move as part of a broader effort to restrict EPA authority over toxic air pollution.

May 8, 2026 — In March 2025 the Trump administration implemented a massive deregulatory initiative by allowing more than 180 industrial facilities to sidestep Clean Air Act requirements through a simple email application process,. By establishing a dedicated inbox, the administration granted two-year compliance reprieves to major polluters—primarily coal-fired power plants and medical sterilizers—based on claims of national security and the alleged unavailability of pollution-control technology,,. This streamlined process bypassed scientific review by EPA experts, leading to multiple lawsuits from community and environmental groups who argue the exemptions pose significant health risks to millions of Americans.

June 15, 2023 — The Supreme Court’s Sackett v. EPA decision significantly narrowed the scope of the Clean Water Act. By replacing the traditional standard of protecting adjacent wetlands with a stricter requirement for a continuous surface connection, the Court has stripped federal oversight from millions of acres of ecologically vital land. This shift ignores scientific consensus regarding how wetlands filter pollutants and mitigate flooding, even when they lack a visible surface link to larger bodies of water. The author warns that this ruling leaves over half of the nation's wetlands vulnerable to dredging and development, potentially degrading drinking water and biodiversity. Ultimately, the source calls for legislative action or state-level intervention to restore the protections necessary for maintaining the nation's aquatic health.
