A coalition of 17 states has filed a lawsuit in federal court seeking to strike down a new Trump administration regulation that significantly narrows the definition of what bodies of water are federally regulated.
The complaint, which attorneys general from California, New York, 15 other states and the District of Columbia filed on May 1 in federal district court in San Francisco, follows similar lawsuits brought by multiple environmental groups in three other district courts. They contend that the new rule violates the Administrative Procedure and Clean Water acts.
