The Environmental Protection Agency will not appeal a January court ruling that found the agency overstepped its authority in trying to regulate water flow in Accotink Creek in Virginia, the state announced Monday.

Virginia Attorney General Ken Cuccinelli said the EPA will accept the ruling of Judge Liam O’Grady, who said the federal agency violated the Clean Water Act and couldn’t order Fairfax County officials to spend money to cut the flow of the creek to protect the habitat of worms, snails and insects.
