The matrix tracks objections and stipulations among the parties regarding evidence related to construction stormwater management and clean fill criteria for the runway expansion.

This legal document covers a 2002 Washington State Pollution Control Hearings Board case in which the Airport Communities Coalition and Citizens Against Airport Expansion challenged the water quality certification issued by the Department of Ecology for the construction of a Third Runway at Seattle-Tacoma International Airport. The hearing examined 20 issues related to stormwater management, water quality standards, and whether adequate assurances existed that the runway project would comply with Section 401 of the Clean Water Act. The case involved the Port of Seattle as a respondent and centered on whether proper environmental safeguards were in place before construction could proceed.
