CHICAGO – Chicago health officials say huge mounds of petroleum coke along the Calumet River must be enclosed within two years to ease health and environmental concerns.
The Chicago Health Department issued regulations on Thursday to try to control a growing public outcry over "petcoke."
The grainy black byproduct of petroleum refining that has been piling up along shipping channels in the Midwest, including Chicago's southeast side.
Residents have complained about soot from the piles blowing into their neighborhoods and fear it could cause health and environmental problems.
The regulations also will require air monitors, paving of roads at the storage sites and daily sweeping.
A spokesman for KCBX Terminals Co. did not immediately respond to phone and email messages seeking comment. The company operates two petcoke storage sites in Chicago.
