Demolition of the former Chemetco copper smelter took another step forward on Tuesday. The demolition is the start of a long clean-up process for the hazardous Metro East eyesore.
The Illinois EPA is overseeing the dismantling of the smelter buildings, which began last year.
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.
