The U.S. Supreme Court delivered a 9-0 opinion in the case of S.D. Warren v. Maine Board of Environmental Protection, rejecting a South African paper company' s bid to exempt five of its hydroelectric dams in Maine from the Clean Water Act.

WASHINGTON, DC - The hydropower industry is about to get its day in court in a Clean Water Act case before the U.S. Supreme Court this February. If the industry wins, rivers everywhere will lose.

In an unexpected addendum today, the United States Supreme Court agreed to hear two wetlands cases and one case on the Clean Water Act's application to hydropower dams. These three cases are expected to show the Court's posture on the reach of the Clean Water Act.

On February 21st, the U.S. Supreme Court will hear oral arguements in three cases that concern the scope of the Clean Water Act: Rapanos v. United States, Carabell v. United States Army Corps of Engineers, and S.D. Warren v. Maine Board of Environmental Protection.
