As was reported last week, follow-up stack testing occurred at both Sterigenics facilities last week Thursday (9/20/18) and Friday (9/21/18). The testing was performed by a third-party independent consultant. The test protocol and methodology was approved by the IEPA. The testing was witnessed by the IEPA, the USEPA, the Village, and the Tri-State Fire Protection District. Mayor Trilla sent a letter to the IEPA requesting that the final test results be sent to the Village by the end of business on Wednesday, September 26th. Below is a statement that Sterigenics forwarded to the Village after the testing was complete.
