The Port of Seattle has begun an important journey that will be continuous. The goals of that journey are to be a national leader in environmental and sustainability programs, and to make our green initiative a substan- tial thread that runs through everything we do. Our employees have embraced these goals fully, including everything from turning off lights at their work stations to writing federal grant proposals for multi-million dollar energy-saving projects. Our employees bring passion and energy to our environmental work just as they did for the 10-year capital investment program that brought you the new Central Terminal, third runway and Concourse A at Seattle-Tacoma International Airport, renewed facilities at Fishermen’s Terminal and Shilshole Bay Marina, and upgraded container cargo terminals that compete successfully in the global marketplace. Admittedly, passion and energy alone cannot solve all of our challenges. We face some highly complex issues that touch many stakeholders and many lives. We don’t have all the answers. We know we need partners with like goals, and we need the appropriate funding for major projects that pay off in the long run but can be quite costly to initiate. The Port of Seattle’s primary function is to create and support the 194,000 jobs in this region that depend upon Port related businesses. But we can’t sustain those businesses without sustaining the environment in which we work. A LETTER FROM TAY YOSHITANI, CEO Scope of Report: This report covers data and activities for the year 2009.

Previous air pollution modeling efforts and current facility expansion activities at Sea-Tac International Airport have raised concerns about elevated nitrogen dioxide (NO2) levels in the surrounding community. The goals for this project were to 1) assess compliance with the 100 micrograms per cubic meter annual national ambient air quality standard (NAAQS) for NO2, 2) quantify any local concentration gradients, and 3) evaluate the impact of aircraft operations on local NO2 levels. The scope of this project included annual NO2 measurements throughout the community; samplers were located in areas near the north and south ends of the airport where aircraft operations would most likely affect ambient concentrations. Three-week integrated NO2 measurements were continuously performed at 16 locations using Yanagisawa NO2 diffusion badges. Additionally, Washington State Department of Ecology (WDOE) performed continuous nitrogen oxides (NOX) measurements using Federal Reference Method chemiluminescent analyzers and collected meteorological data at two of the sampling locations. Annual average NO2 measurements at all sites were well below the NAAQS. Consistent spatial concentration gradients were observed throughout the study. NO2 levels decreased from east to west. NO2 levels generally decreased with distance from both the airport runways and local freeways. Hourly NOX and meteorological data from WDOE monitoring stations were used to identify local source impacts by comparing measured NOX levels by wind direction. Because NOX is primarily emitted as nitric oxide (NO), concentration of this species varied more with wind direction than NO2. Evidence of a small but discernable airport impact on NOX levels was observed near…
