Judge fines DTE, its Zug Island facility $100 million for Clean Air Act violations

February 18, 2026

A federal judge has ordered DTE Energy and its Zug Island subsidiary, EES Coke Battery, to pay $100 million in penalties for violating the Clean Air Act through excessive sulfur dioxide emissions. The ruling also requires the company to obtain proper permits, establish a community air quality committee funded with $20 million, and fund local environmental improvement projects. Judge Gershwin Drain determined that DTE exercised substantial control over the facility's operations despite the company's claims of non-responsibility, making them legally liable for the violations.

Who is affected

DTE Energy and its EES Coke Battery subsidiary (facing financial penalties and compliance requirements)
Residents of Detroit's 48217 zip code, particularly Southwest Detroit
Communities in River Rouge and Ecorse
The city of River Rouge (intervener in the lawsuit)
Sierra Club (intervener in the lawsuit)
U.S. steel industry (potentially affected by coke supply)
Environmental activists like Theresa Landrum
Students and households near Zug Island who may benefit from air quality improvements

What action is being taken

DTE Energy is planning to appeal Judge Drain's order to the 6th Circuit Court
The EPA, Sierra Club, and city of River Rouge are submitting a joint proposed judgment by Friday
EES Coke Battery continues operating within the limits of its original state permit
DTE and EES Coke Battery are required to apply for and obtain New Source Review permits
A seven-member community air quality committee is being formed with $20 million in funding

Why it matters

This ruling is significant because it establishes corporate accountability for environmental violations affecting vulnerable communities that have suffered from long-term air pollution exposure. The decision demonstrates that parent companies cannot evade responsibility for their subsidiaries' Clean Air Act violations by claiming lack of control. Sulfur dioxide emissions pose serious health risks, including asthma attacks, respiratory problems, and premature mortality through fine particulate matter formation. The $20 million community fund represents a direct investment in improving air quality and public health for residents who have disproportionately borne the environmental burden of industrial operations. The case also signals the Justice Department's commitment to enforcing environmental laws and ensuring compliance across all businesses.

What's next

DTE will appeal the ruling to the 6th Circuit Court of Appeals
The EPA, Sierra Club, and city of River Rouge must submit a joint proposed judgment by Friday
DTE and EES Coke Battery must apply for and obtain New Source Review permits to comply with the Clean Air Act
A seven-member community air quality committee will be formed with residents and environmental advocates
The committee will develop and implement air quality improvement projects, potentially including HEPA air purifiers for households, school filtration systems, and weatherization programs
Michigan Department of Environment, Great Lakes, and Energy may issue a new permit for EES Coke Battery that could require updated pollution controls
