PORT OF SEATTLE COMMISSION MOTION TO CONSIDER 
ACCELERATED EMISSIONS STANDARDS 
STATEMENT IN SUPPORT OF MOTION 
The Port of Seattle Commission has established guiding policy directing that that Port will strive in all its
business operations to become "the greenest, cleanest, most energy efficient port in North America." 
This vision recognizes that Port operations must be economically, environmentally and socially
sustainable as the Port moves into its second century of operations. The need to develop sustainable
business practices has been a key impetus for the Port's Clean Air Strategy and its trucking programs. A
comprehensive strategy for addressing the impacts of the Port's maritime activities is a priority that will
enable future increases in cargo movement through Puget Sound and the job growth associated with
that economic activity. 
While the Port's current truck program will improve the drayage fleet, it does not meet the high bar that
the Commission has set for Port activities. The program's truck replacement timeline and enforcement
strategy should be leading national programs. The impact of trucks operations, including particularly
truck emissions, on residents and workers in Port-adjacent neighborhoods remains an issue that
requires concerted attention. 
As the first elements of the Port's truck program go into full effect as of January 2011, it is time to
analyze whether stronger measures to clean up the Port's truck fleet are appropriate. Therefore, the
Commission wants to consider proposals in the coming year that would move the truck fleet serving the
Port towards becoming the greenest, cleanest and most efficient in North America. 
Motion 
The executive shall present to the Commissioners sitting in public session three alternative plans for
improving the Port's drayage fleet no later than July 15, 2011. The alternative plans shall each contain
the following elements: 
1)   A timeline for bringing 100% of trucks operating at the Port into compliance with EPA 2007
standards no later than 2013 and EPA 2010 standards by 2015; 
2)   Measures to enforce truck program requirements that allow the Port to directly monitor
compliance; directly gather and analyze data; and exclude non-compliant trucks and trucking
companies from Port terminals; and 
3)   Identified stable funding mechanisms for purchasing and maintaining trucks that meet EPA
standards. 
To allow for appropriate public discussion, the plans should be made available to all identified
stakeholders and the general public no later than June 15, 2011.
