County of Maui, Hawaii v. Hawaii Wildlife Fund

The Supreme Court of the United States was recently asked to decide whether the Clean Water Act requires a permit for the discharge of pollutants that originate from a point source but are conveyed to navigable waters by a nonpoint source. Vacating the Ninth Circuit’s “fairly traceable” test, the Court held the Clean Water Act requires a permit when there is a direct discharge of pollutants from a point source into navigable waters or when there is the “functional equivalent of a direct discharge.”
