Arch Coal Inc. will pay $2 million to settle a lawsuit over selenium pollution in West Virginia waterways.
The environmental groups that sued last year say the deal holds the St. Louis-based company responsible for past damage and prevents more.
Arch spokeswoman Kim Link said Monday the case involves five discharge points and subsidiaries Coal-Mac Inc. and Mingo Logan Coal Co.
She says Arch will install treatment systems and take other precautions to ensure consistent compliance with pollution limits.
