Mirant Clean Air Settlement

WASHINGTON, D.C. - In a joint federal-state settlement, Mirant Mid-Atlantic (Mirant) has agreed to eliminate nearly 29,000 tons of harmful pollution each year generated by its four electricity generating plants in Maryland and Virginia. The Department of Justice, the U.S. Environmental Protection Agency (EPA), the Commonwealth of Virginia and the State of Maryland worked jointly on this enforcement action, which will reduce significantly output of nitrogen oxides (NOx) throughout the region.

The amended Clean Air Act consent decree, lodged today in U.S. District Court for the Eastern District of Virginia, specifically resolves federal and state claims that in 2003, Mirant violated the NOx emissions limitation set forth in the operating permit for its Potomac River plant in Alexandria, Virginia.
