Request for Administrative Order for Lagoon #3 Bypass and SEPA Addendum

Notes

This document collection includes a January 2001 letter from Port of Seattle requesting an administrative order for Lagoon #3 bypass at Seattle-Tacoma International Airport, and a January 2002 SEPA Addendum for the Industrial Wastewater System Lagoon #3 Upgrades and Expansion. The project aims to increase lagoon capacity from 26 million gallons to 76 million gallons while lining and remediating the facility. During construction, Lagoon #3 would be taken out of service, potentially requiring untreated industrial wastewater flows to be released to Des Moines Creek.
