DTE Energy Faces Federal Trial Over Dangerous Air Pollution Allegations
10 Oct
Summary
- DTE Energy accused of allowing industrial plant to release harmful air pollution
- Facility made coke, a coal-based fuel, and was a major source of sulfur dioxide
- Experts estimate DTE gained $70-94 million while facility violated Clean Air Act
In September 2025, one of Michigan's largest utilities, DTE Energy, is facing a federal trial over allegations that it allowed one of its industrial plants to release dangerous levels of air pollution. The case, which could set a precedent for holding large utilities accountable, centers around DTE's coke battery facility on Zug Island.
The plant, which produces coke, a coal-based fuel used in steelmaking, has long been a source of harmful sulfur dioxide pollution. According to expert witness testimony, DTE Energy Services, a subsidiary of DTE Energy, actively controls the environmental decisions and daily operations of the facility, rather than being a "distant, hands-off investor."
Prosecutors estimate that the DTE-owned companies gained between $70 million and $94 million while the facility was out of compliance with the Clean Air Act. Sulfur dioxide can trigger asthma attacks, damage lungs, and worsen heart disease, posing significant health risks to the nearby communities.
The trial could set a precedent for how courts across the U.S. treat utilities accused of prioritizing profits over public health. The outcome may influence national standards for environmental accountability, potentially leading to stronger pollution controls and community-focused remedies, such as air purifiers, electric vehicle infrastructure, and solar panels.
