CHICAGO (AP) - A Chicago resident who has seen piles of petroleum coke build up in her neighborhood says rules proposed by state officials to control how the substance is handled don’t go far enough.

Kate Koval says she’d like to see a ban of the material called “petcoke.” It’s a byproduct of oil refining that’s been accumulating along Midwest shipping channels and has sparked health and environmental concerns.

While it’s not classified as hazardous, Chicago residents have complained that it coats their homes and aggravates conditions like asthma, particularly when it’s windy.

Gov. Pat Quinn announced emergency rules Monday to regulate how the material is stored and handled. State environmental officials are expected to approve the rules by the end of the month. The proposal includes having facilities install dust suppression systems.
