Brandywine Coal Ash Landfill is a 217-acre landfill and as of 2017, it accepted waste from Maryland's Chalk Point and Morgantown power plants. It also contains coal ash from the Potomac River generating station, generated prior to 2007. The landfill has been in operation since the 1970s.
Due to illegal discharges of toxic pollutants into Mataponi Creek and its tributaries, EIP and other citizen groups sent Mirant Mid-Atlantic a notice of intent to sue in 2009 for violations of the Clean Water Act. The Maryland Department of the Environment (MDE) filed suit in April, 2010 for violations of the CWA and state law, and a $1.9 million settlement was reached in January, 2013.
This site is among the U.S. Environmental Protection Agency's list of potential damage cases.
