A September 2000 letter from Northwest Hydraulic Consultants, written on behalf of the Airport Communities Coalition, raises serious technical concerns about the Stormwater Management Plan for Seattle-Tacoma International Airport's proposed third runway. The letter highlights findings from King County reviewers showing that multiple stormwater facilities in the plan were unverified, potentially infeasible, or unlikely to meet required flow control performance standards. The consultants argue that the review timeline was insufficient and that the Port of Seattle had a history of failing to deliver promised stormwater mitigation measures.

In September 2000, Northwest Hydraulic Consultants submitted preliminary technical comments on behalf of the Airport Communities Coalition, raising serious concerns about the adequacy of the Stormwater Management Plan for Seattle-Tacoma International Airport's proposed third runway expansion. The letter highlights findings from King County's independent review, which identified numerous cases where proposed stormwater control facilities were unverified, infeasible, or unlikely to meet required flow control performance standards. The consultants warned that the compressed public review timeline was insufficient for thorough evaluation of the plan before Ecology's 401 Certification decision.

In September 2000, King County's Department of Natural Resources provided a technical review of the Port of Seattle's Comprehensive Stormwater Management Plan (SMP) for proposed Master Plan Update improvements at Seattle-Tacoma International Airport. The review found no fatal flaws in the plan's approach to meeting King County's stormwater standards, but identified inconsistencies in flow control calculations and water quality measures that needed to be resolved before final permitting. King County also emphasized the importance of rigorous erosion and sediment control during construction and recommended that Ecology and the Port establish a joint compliance team to oversee implementation of the complex, multi-year project.
