The Supreme Court upended a Biden administration environmental regulation broadly defining and regulating which water sources the federal government has authority over.
From the above:
"The case centered on Michael and Chantell Sackett, two Idaho residents whom the EPA prohibited from building a home near a wetland years ago, citing the Clean Water Act (CWA) of 1972
"The EPA ordered the Sacketts to restore the site, threatening penalties of over $40,000 per day," Alito's majority opinion stated. "The EPA classified the wetlands on the Sacketts’ lot as 'waters of the United States' because they were near a ditch that fed into a creek, which fed into Priest Lake, a navigable, intrastate lake. The Sacketts sued, alleging that their property was not 'waters of the United States.'""
