The U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers plan by Sept. 1 to have a narrower definition of "waters of the United States" to comply with last month's U.S. Supreme Court decision that the agencies had exceeded their authority under the federal Clean Water Act.

The agencies said Monday they will reset the definition to comply with the high court's May 25 ruling in Sackett v. Environmental Protection Agency that the agencies had overreached their regulatory scope over wetlands.
