Section 430 ILCS 45/7 - Review of response actions and revisions of plans(a) Any business that has a significant release of a chemical substance from a facility shall provide a written report to the Agency within 30 days of the incident or of designation thereof by the Agency or the IEMA. The report shall include a copy of the Chemical Safety Contingency Plan unless a copy of the current plan has been previously provided to the Agency, and shall explain the nature, cause, and known effects of the release, the actions taken to mitigate the effects of the release, and an assessment of the response actions and the Chemical Safety Contingency Plan. After submission to the Agency, the report shall be made available to the public under the Freedom of Information Act.(b) The Agency shall evaluate the report and any necessary supplemental information regarding the on-scene circumstances, actions, and results associated with the incident. Within 60 days of the receipt of the report, the Agency shall provide to the IEMA the report, the supplemental information and, if appropriate, any written findings and recommended revisions that the Agency considers necessary to improve the plan. The findings and recommendations shall be made available to the public under the Freedom of Information Act.(c) The IEMA shall review the submission provided by the Agency and determine if the Chemical Safety Contingency Plan meets the provisions of subsection (b) of Section 4, was properly adhered to, and what improvements could be provided to address such an incident. Within 60 days of receipt of the submission, the IEMA may require, by written notice, the business to revise the plan in accordance with the specified terms and schedule as are necessary to improve the plan. In issuing notice, IEMA shall consider the nature of the facility, the actual and potential impacts of the release, the character of the area including surrounding land uses, and the technical feasibility and economic reasonableness of the revision. The notice shall be made available to the public under the Freedom of Information Act.(d) Any required revision shall be binding upon the business unless, within 30 days of receipt of the notification, the business submits to the IEMA a written request for reconsideration, including the reasons therefor and, if appropriate, any alternative proposal for improving the plan.(e) Within 30 days after receipt of a request for reconsideration, the IEMA shall make a final determination in writing that affirms, rejects, or modifies the required revision of the plan. This final determination shall take effect following the 35th day after receipt by the business of notice of the determination, unless before that date the business files a petition for review of the decision under the Administrative Review Law. The determination shall be made available to the public under the Freedom of Information Act.(f) When, after a significant release, measures are taken by a business that, if taken previously, would have made the release less likely to occur, evidence of the subsequent measures is not admissible to prove negligence or culpable conduct in connection with the release. This subsection does not require the exclusion of evidence of subsequent measures when offered for another purpose, such as proving ownership, control, or feasibility of precautionary measures, if controverted, or for impeachment.
