On April 12, a significant Clean Water Act (CWA) ruling has been made by the U.S. Court of Appeals for the Fourth Circuit. The Fourth Circuit, in a split decision, held, in a case of first impression in this circuit, that the movement of a discharged pollutant through groundwater to navigable waters can constitute a violation of the CWA’s requirement that discharges of a pollutant from a point source to navigable waters is illegal unless the discharge has been permitted. The case is Upstate Forever and Savannah Riverkeeper v. Kinder Morgan Energy Partners, LP.
A few weeks ago, a similar decision was rendered by the U.S. Court of Appeals for the Ninth Circuit in the case of Hawai’i Wildlife Fund, et al., v. County of Maui.
