By a 9-0 vote, the high court upheld a ruling by the Maine Supreme Judicial Court that allowed the state to set additional conditions on a hydropower dam owner in exchange for renewing his license to operate five dams on the Presumpscot River.
A ruling against Maine would have eliminated a key regulatory tool used by nearly every state to improve the quality of waterways. The state said the operation of the dams had caused long stretches of the natural river bed to be essentially dry.
"The alteration of water quality ... is a risk inherent in limiting river flow and releasing water through turbines," Justice David Souter wrote. "Changes in the river like these fall within a state's legitimate legislative business and the Clean Water Act provides for a system that respects the states' concerns."
