Illinois lawmakers urged to ‘step up’ and ‘fight like hell’ as EPA moves to cut wetlands protections

After the U.S. Environmental Protection Agency announced Monday it is redefining the scope of the nation’s bedrock clean water law to limit the wetlands it protects from pollution and destruction, environmental groups are urging Illinois legislators to establish safeguards. The state has already lost 90% of its original wetlands to urban development and agriculture.

The Trump administration’s action builds on a 2023 Supreme Court ruling in Sackett v. EPA that sharply limited the U.S. government’s authority to regulate water pollution in certain wetlands, effectively stripping 72% of remaining wetlands in Illinois — more than 700,000 acres — of federal protections and leaving them vulnerable to “catastrophic” loss, according to a September analysis by University of Illinois researchers.
