This legal brief was filed by Citizens Against Sea-Tac Expansion before the Washington Supreme Court, challenging a decision by the Pollution Control Hearings Board regarding the expansion of Seattle-Tacoma International Airport. The group argues that state regulators improperly allowed the Port of Seattle to rely on future, unwritten stormwater permits as proof that airport runoff would meet water quality standards, and that regulators wrongly pre-authorized pollution mixing zones in nearby waterways without sufficient oversight. The case centers on whether proper environmental protections were in place before approving the airport expansion project.Open full document

Opening brief filed by Citizens Against Sea-Tac Expansion before the Washington Supreme Court challenging the Pollution Control Hearings Board’s decision regarding a Section 401 water quality certification for the Port of Seattle. The brief argues that the PCHB erred in allowing Ecology to rely on future NPDES permits as reasonable assurance that stormwater discharges will comply with water quality standards, and in pre-authorizing mixing zones. The case concerns stormwater discharge regulation at Seattle-Tacoma International Airport.
