Many acres of wetlands across the vast Mississippi River basin would lose federal protection under a new rule proposed by the U.S. Environmental Protection Agency.

Agricultural and builders’ groups have called it a win for private property owners. Environmental groups warn that it will exacerbate costly challenges like flooding that already plague the river and its tributaries.

The new rule, proposed Nov. 17, is the latest in a convoluted, decadeslong fight over which streams and wetlands qualify as “Waters of the United States” and thus are regulated by the federal government under the Clean Water Act. Environmental advocates claim more expansive federal protections are needed to preserve the country’s natural resources, while some farmers and homebuilders argue the government is overstepping its authority to control how they use their land.

A landmark 2023 U.S. Supreme Court case, Sackett v. EPA, used a narrow definition to determine which wetlands get federal protections. EPA Administrator Lee Zeldin promised earlier this year that the agency would adjust its definitions to comply. The proposed rule delivers on that promise.

The proposal will be open for public comment for 45 days before it moves forward.
