The Illinois Environmental Protection Agency has filed emergency rules with the Illinois Pollution Control Board to deal with petroleum coke piles in Chicago.
Petroleum coke or "petcoke" is a black dust that is a byproduct of oil refining. Chicago residents raised concerns after the dust blew into neighborhoods. The state EPA filed the emergency rules on Thursday. They will take effect after the state Pollution Control Board files them with the Illinois Secretary of State. The EPA says that could happen as soon as Jan. 23.
Environmental groups, like the Natural Resources Defense Council, have the emergency rules fall short and more action is needed.
The state and city are suing to stop the storage of petcoke along the Calumet River on Chicago's Southeast Side.
