After more than ten years of litigation and settlement negotiations with DTE Energy Company and Detroit Edison Company (DTE), the company and the United States (through DOJ) have agreed to final settlement terms. The final consent decree resolves Clean Air Act New Source Review violations cited in three Notices/Findings of Violation at DTE's five coal-fired power plants in southeast Michigan. To resolve the alleged violations, DTE has agreed to retrofit, refuel, or repower all coal-fired units at its Belle River, River Rouge, St. Clair, and Trenton Channel stations, and meet enforceable sulfur dioxide (SO2), nitrogen oxide (NOx) and particulate matter emission rates at its Monroe Generation Station. SO2 emissions from the System will be reduced from approximately 123,000 tons per year (tpy) in 2010 to less than 9,500 tpy by 2031 and NOx emissions from 37,500 tpy in 2010 to 13,400 tpy in 2031. The company has also agreed to pay a $1.8M civil penalty and to perform a $5.5M Clean Bus Replacement Program as an environmental mitigation project. Michigan EGLE is not a party to the consent decree but supports it. Sierra Club is a party to the decree, and has also negotiated an additional separate consent decree with DTE to address unit retirements and additional mitigation projects.
