ADEQ | Arizona’s Department of Environmental Quality has opened a public comment period through March 2, 2026, on a proposed rule to revise how annual CPI-based inflation adjustments are calculated for water quality fees, aiming to better align increases with actual inflation without adding new fees or raising existing caps.

InsideEVs | A University of Southern California study using satellite and vehicle registration data found that for every 200 new zero-emission vehicles added to a California neighborhood, nitrogen dioxide levels fell by 1.1%, providing strong evidence that EV adoption is measurably improving urban air quality.

Orange County Register | The National Weather Service has issued an air quality alert and mandatory wood-burning ban for parts of Southern California through Feb. 3 due to elevated fine particle pollution, urging residents to limit outdoor exposure and reduce activities that worsen air quality.

Nature | A large UK Biobank study identifies 30 diseases linked to air pollution exposure and finds that circulating proteins mediate nearly 24% of this risk, introducing a novel Air Pollution Protein Risk Score (APPRS) to improve personalized disease prediction and public health interventions.

Oregon Live | The National Weather Service has issued an air stagnation advisory for Oregon’s Lower Treasure Valley through Friday morning, warning that a surface inversion trapping pollutants may lead to poor air quality and heightened health risks for individuals with respiratory conditions.

Rivian Stories | Rivian collaborated with the production team of Grey’s Anatomy to transform its all-electric Commercial Van into a custom “vanbulance” for Season 22, showcasing zero-emissions emergency vehicle innovation designed for both on-screen authenticity and potential real-world applications.

POLITICO Pro | EPA Administrator Lee Zeldin faces a looming Clean Air Act deadline to determine which regions fail to meet the Biden-era strengthened soot standard even as the Trump administration seeks to overturn the rule in federal court.

EurekAlert! | A new University of Notre Dame study finds that about 40% of the 100,000 annual U.S. premature deaths linked to PM2.5 are caused by cross-state pollution and introduces a simplified, data-driven framework to help policymakers identify and address states responsible for harmful interstate air pollution.

AP News | The Trump administration’s EPA has proposed approving ozone control plans for eight states and moving to roll back the Biden-era “Good Neighbor” rule limiting cross-state smokestack emissions, drawing criticism from environmental groups who warn it could weaken federal oversight of interstate air pollution.

The Detroit News | Health advocates warn that the EPA’s proposed rollback of federal particulate matter standards would disproportionately harm Michigan residents near industrial sources by weakening protections for people with heart and lung conditions.
