Flying high: Runway Project Overcomes Tough Obstacles

This article describes the difficulties in overcoming environmental obstacles to construct a third runway at Seattle-Tacoma (Sea-Tac) International Airport. The $1.3 billion project was saddled with the most stringent environmental impact mitigation permits issued in the state’s history. The raised embankment for the runway required 17 million cubic yards of fill dirt in an area constrained by wetlands, creeks and public roads. To minimize impact on air quality, a local refinery provided ultra-low-sulfur diesel fuel for the project’s trucks hauling the fill. The article also discusses storm-water runoff systems required to meet environmental permitting requirements and minimize effect on fish habitat and other wetland functions.
