New and Proposed Rules

The information available through this website is provided solely for the convenience of interested persons. It should not be cited as an official or authoritative source. Illinois rulemakings are governed by the Illinois Administrative Procedures Act and applicable administrative rules. The official version of the Illinois Administrative Code is maintained and published by the Secretary of State. The Illinois EPA does not review or edit the information available through this website, and any deviation from the official versions is unintentional. In addition, amendments, Illinois Pollution Control Board and court decisions, and other proceedings may affect statute and rule text, interpretation, validity, and constitutionality. You are urged to consult official documents or contact legal counsel of your choice regarding state and federal statutes and regulations.

Please note that many of the rules administered by the Illinois EPA are Illinois Pollution Control Board Regulations.  If you do not find the rules you are looking for please try the Pending Rulemakings page on the Illinois Pollution Control Board website.
