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.
The U.S. Environmental Protection Agency has added the Washington County Lead District-Furnace Creek site in Washington County, Missouri, to the federal Superfund National Priorities List (NPL).
The NPL is a list of the nation's hazardous waste sites with the highest priority for cleanup.
Federal officials say Arch Coal will pay $4 million in fines and change some mining practices to settle alleged Clean Water Act violations in Virginia, West Virginia and Kentucky.
The deal announced Tuesday is between St. Louis-based Arch, the Environmental Protection Agency and the Department of Justice.
