PCHB No. 01-160: Findings of Fact, Conclusions of Law, and Order — ACC and CASE v. Ecology and Port Of Seattle

This document records a 2002 Washington State Pollution Control Hearings Board case in which community groups challenged the water quality certification issued for the construction of a third runway at Seattle-Tacoma International Airport. The Airport Communities Coalition and Citizens Against Airport Expansion argued that the Department of Ecology's approval did not provide adequate assurance that the project would comply with Clean Water Act Section 401 and state water quality laws, particularly regarding stormwater management. The Board examined 20 disputed issues covering topics such as stormwater impacts, detention system safety, and the scope of the certification.
