SUBJECT:  Special Order of Business: Recognition of the Winners of the 2010 Seattle-
Tacoma International Airport Green Gateway Environmental Excellence Awards
Program 

In 2010, Aviation Environmental staff created the Seattle-Tacoma International Airport Green
Gateway Environmental Excellence Award Program ("Awards Program") as a way to annually
recognize Airport tenants and airlines for outstanding environmental leadership. The Awards
Program is also intended to encourage continual environmental improvement by tenants and
airlines and acknowledge the critical role they play in assisting the Port in meeting its
environmental goals. 
The Awards Program is designed such that the Port may award one or more awards each year,
depending on the quality of the nominations it receives. Nominations are accepted for any
project, process, or action that promotes environmental leadership and stewardship in one of
three categories:
Environmental Performance 
Environmental Education and Outreach 
Environmental Innovation 
Between January and March, 2011, the Port accepted award nominations for projects, processes
or actions completed during 2010. Nominations were evaluated by a panel of Aviation Division
staff and managers in accordance with criteria established for each category.  This panel
determined two nominations in the Environmental Performance category met established criteria,
and demonstrated environmental stewardship and/or leadership at Seattle Tacoma International
Airport (Sea-Tac Airport). Both nominations were selected to receive a 2010 Environmental
Excellence Award.
