Port of Seattle SEPA addendum (POS SEPA No. 01-05, AR 049967) dated March 6, 2001, for the Seattle-Tacoma International Airport North Electric Service Upgrade project. Documents a revised proposal for the North Main Service Point site location and 12.5 kV cable route connecting to the Bow Lake Substation via International Boulevard near South 176th Street.

These are prepared talking points for Washington State Department of Ecology officials attending public meetings on January 26-27, 2001, regarding the proposed Third Runway (3RW) at Seattle-Tacoma International Airport. The notes address 17 anticipated public questions covering topics such as Ecology's 401 Water Quality Certification review process, the use of Port-funded consultants, SEPA compliance, wetlands impacts, and whether the project was receiving special political consideration. Officials emphasized that no approval would be granted until the project demonstrated full compliance with all applicable environmental laws and regulations.

The Port of Seattle requested regulatory approval to temporarily take Lagoon #3, part of Seattle-Tacoma International Airport's industrial wastewater treatment system, out of service from April through December 2002 for remediation and expansion work. The project aimed to increase the lagoon's storage capacity from 26 million gallons to 76 million gallons, add a protective liner, and rebuild berms to prevent untreated wastewater from seeping into the ground. During the construction period, some untreated industrial wastewater flows could potentially be released into Des Moines Creek as unavoidable bypasses.

Email from Ann Kenny (Ecology, Shorelands and Environmental Assistance Program) dated November 30, 2000, to Leslie Seffern (ATG) and Erik Stockdale, circulating a draft response letter to Bill Garrity, Executive Director of CECW (Consulting Engineers Council of Washington), regarding his November 22, 2000 letter challenging Ecology’s Request for Bid process for selecting a wetland consultant.

In October 2000, attorneys representing the Airport Communities Coalition — comprising the cities of Burien, Des Moines, Federal Way, Normandy Park, and Tukwila, along with the Highline School District — submitted formal comments objecting to the Puget Sound Regional Council's Draft Environmental Impact Statement for the Destination 2030 Metropolitan Transportation Plan. The letter argues that the DEIS violates SEPA requirements by refusing to analyze aviation alternatives, including whether Sea-Tac's controversial third runway project was still justified given changed demand forecasts and its ballooning costs. It also challenges the DEIS for failing to provide current data on aircraft noise impacts, noting that noise contours around Sea-Tac appeared to be growing rather than shrinking as previously forecast.
