In the latest development in nationwide disputes over the scope of the Clean Water Act, a federal judge in North Dakota has issued a preliminary injunction that blocks a Biden Administration rule over which waters can be regulated.

The ruling applies to streams, wetlands and other bodies of waters in 24 states that filed suit against the Environmental Protection Agency to block a revised definition of the WOTUS (Waters of the United States) rule, which spells out which waters are protected under the Clean Water Act.
