A coalition of environmental groups sued the Port of Seattle on Monday to stop the lease of a terminal to Royal Dutch Shell Plc’s Arctic oil drilling fleet, arguing a proper environmental review was never conducted, court records showed.

Earthjustice, along with other groups including the Sierra Club, filed the suit in a Washington state court, alleging the drilling operation was substantially different from the terminal’s prior use, meaning an environmental review had to be done under state law.

The complaint against the port and Foss Maritime Co, which would work for Shell under the two-year lease, also alleged that officials reached the arrangement without public disclosure and that the fleet could pollute the area’s water.
