Water Quality and Water Management Review of Sea-Tac Airport Stormwater Plan

Notes

A letter from Water Resources Consulting L.L.C. to the U.S. Army Corps of Engineers and Washington State Department of Ecology, reviewing water quality and water management aspects of the SeaTac Airport Master Plan Update. The review, requested by the Airport Communities Coalition, identifies serious deficiencies in the Comprehensive Stormwater Management Plan, including ongoing violations of Washington State Water Quality Standards, inadequate Best Management Practices, and concerns about contaminant transport. The author concludes there is no basis for Clean Water Act Section 401 certification or Section 404 approval.
