Illinois EPA Seeks Order To Stop Sterigenics Operations

WILLOWBROOK, IL — The Illinois EPA is seeking an order directing Sterigenics to stop operations until a full review of the additional modeling and risk assessment can be completed or until the U.S. EPA can assure the community that Sterigenics’ operations pose no elevated health risks. According to the agency, the Illinois EPA has referred an enforcement action to the Illinois Attorney General's Office against Sterigenics, based on the findings of the Agency for Toxic Substances and Disease Registry.

The agency said on Sept. 28 Illinois officials and local community representatives met with U.S. EPA to discuss the status of U.S. EPA's ongoing evaluation and testing at Sterigenics. According to the agency, while progress has been made, it will take weeks or months before U.S. EPA will be in a position to provide an updated risk assessment and propose any resulting changes to relevant regulations.

At an event on Tuesday, State Sen. John Curran also called for Sterigenics to cease operations.

“I commend the Illinois EPA for demanding Sterigenics act responsibly and temporarily halt operations,” said Curran. “I’ve been in constant communication with the Governor’s office and officials within the EPA throughout this entire ordeal and to have their support is critical.”

In addition to the agency requesting an order to stop Sterigenics from continuing operations, the agency requests, as an alternative, the Attorney General's Office pursue a violation of Section 9(a) of the Illinois Environmental Protection Act. Illinois EPA said it also requests Sterigenics pursue EtO emission limits for the Willowbrook facility that would be memorialized in an amended permit.

“Despite area residents demanding action and answers, Sterigenics has remained unresponsive. They are determined to place business before the health and wellbeing of those in the community. Enough is enough,” said Curran. “This letter is a definitive call to action, ensuring that no further harm comes to the people of Willowbrook or surrounding areas.”
