The Illinois Environmental Protection Agency wants the state to require a rail company to clean up after last week's derailment of freight cars filled with ethanol.
The EPA said Thursday that it's asked the attorney general's office to take enforcement action against Iowa Interstate Railroad.
Tanker cars operated by the railroad derailed early Friday outside the small northern Illinois community of Tiskilwa.
The train was shipping ethanol and other materials for Decatur-based corn processor Archer Daniels Midland Co.
The derailment touched off a fire that burned at least six tanker cars and led to the temporary evacuation of all 800 residents of Tiskilwa.
The EPA wants the rail company to pay for environmental cleanup and ongoing testing of the soil, groundwater and surface water in the area.
