EPA, Firm Reach Settlement Over Coal Ash Dumping
ST. LOUIS - The U.S. Environmental Protection Agency is proposing a settlement with a suburban St. Louis company over the unauthorized dumping of 140,000 tons of coal ash.
The St. Louis Post-Dispatch reports the EPA said Thursday the settlement would require Rotary Drilling Supply of Jefferson County to place a protective cap over ash piles. The company would also be required to install controls to prevent pollutants from further migration.
The EPA says Rotary Drilling and another company had a contract to dispose of coal ash from the utility Ameren Missouri's Rush Island plant. The ash contains harmful metals like mercury and arsenic, and the dumping fouled wetlands and water.
The settlement, subject to a 30-day public comment period, also requires Rotary Drilling to purchase wetland mitigation bank credits.
