The EES Coke facility (Facility) is located on Zug Island, between River Rouge and Detroit, in an area that fails to meet federal standards for sulfur dioxide in the air. The court found that the Facility increased its sulfur dioxide pollution as a result of changes the company sought to its state air permit in 2014. For example, the Facility emitted over 3,200 tons of sulfur dioxide pollution in 2018, compared to permitted baseline sulfur dioxide levels of under 2,100 tons per year. The court found that DTE Energy Company, DTE Energy Resources LLC, and DTE Energy Services Inc. were all liable as operators of the EES Coke facility. Turning to civil penalty, the court found that a penalty of $100 million was appropriate for the primary claim.
