On Dec. 13, 2013, flames and heavy smoke shot out of a chemical plant after an explosion was reported at an Alsip chemical plant.
Madigan filed the lawsuit at the request of the Illinois Environmental Protection Agency.
The agency wants an injunction ordering Blue Island Phenol to conduct an analysis that lead to the explosion.
Two employees were burned in the explosion and fire, which destroyed a storage facility and damaged other buildings at the plant.
