Chicago ─Illinois Attorney General Lisa Madigan announced Thursday that Fox Valley Systems aerosol paint manufacturing company must remain closed until the cause of the March 6 explosion and fire is determined.

The explosion and fire at the company, located at 640 Industrial Dr. in Cary, caused injuries to three employees and resulted in the evacuation of the facility.

Madigan’s office filed a three-count complaint against Fox Valley Systems and FVMS, Inc. alleging substantial danger to the environment, air pollution, and water pollution hazards resulting from the explosion and fire, according to a press release issued from the attorney general's office.

Each count seeks the maximum statutory civil penalty of $50,000 per violation and $10,000 for each day the company is in violation. Fox Valley Systems manufactures spray paints used for marking and striping surfaces.

“We must determine what circumstances led to this dangerous event, mitigate any environmental damage and ensure the facility is safe for workers to return,” Madigan said in a press release.

Also on Thursday, the McHenry County Circuit Court entered an agreed order that Madigan’s office filed with defendants Fox Valley Systems, Inc. and FVMS, Inc.

The agreed order requires the Fox Valley Systems to conduct a complete analysis of events leading up to the explosion, and present a plan for approval to prevent future incidents before the facility can re-open.

In addition, the company must secure the damaged facility to prevent access, ensure that chemicals and other materials remaining at the site are safely removed and provide Madigan’s office and the Illinois EPA with the names and quantities of the chemicals released into the air or into sewer drains and the ground surrounding the plant after the incident.

Assistant Attorneys General Nichole Sangha and Gerald Karr are handling the case for Madigan’s Environmental Bureau.
