Community groups C.A.S.E. and the Airport Communities Coalition have appealed Sea-Tac Airport's water pollution permit, pushing for stronger environmental protections while the Port of Seattle seeks to weaken it. Their key concerns include toxic de-icing chemicals entering local streams, inadequate protection of Lake Reba, contaminated soil used in the third-runway construction, and years of delayed compliance with clean-water standards. The groups argue the permit fails to meet legally required industrial pollution controls and undermines previous rulings by the Pollution Control Hearings Board.Open full document
