ST. LOUIS (AP) — President Joe Biden’s administration on Friday finalized regulations that protect hundreds of thousands of small streams, wetlands and other waterways, repealing a Trump-era rule that federal courts had thrown out and that environmentalists said left waterways vulnerable to pollution.
The rule defines which “waters of the United States” are protected by the Clean Water Act. For decades, the term has been a flashpoint between environmental groups that want to broaden limits on pollution entering the nation’s waters and farmers, builders and industry groups that say extending regulations too far is onerous for business.
The Environmental Protection Agency and the Department of the Army said the reworked rule is based on definitions that were in place prior to 2015. Federal officials said they wrote a “durable definition” of waterways to reduce uncertainty.
