MEMORANDUM                 Date_April 24, 2009_ 

TO:      Tay Yoshitani, Chief Executive Officer, Port of Seattle 
Tim Farrell, Executive Director, Port of Tacoma 
FROM:    Wayne Grotheer, Director, Seaport Professional & Technical Svcs, Port of Seattle 
Louis W. Paulsen, Chief Sustainable Development Officer, Port of Tacoma 
SUBJECT:  Briefing on Northwest Ports Clean Air Strategy Implementation Status 
The purpose of this briefing is to provide the respective Commissions of the Port of Seattle and
Port of Tacoma an update on progress towards reaching the short-term (2010) performance
measures under the Northwest Ports Clean Air Strategy. 
BACKGROUND 
On January 7 and 22, 2008, respectively, the Commissioners of the Ports of Tacoma and Seattle
jointly adopted the Northwest Ports Clean Air Strategy, a voluntary and collaborative effort of
the Ports of Seattle, Tacoma and Vancouver (B.C.) to reduce maritime and port-related emissions
that affect air quality and climate change in the Pacific Northwest. Both ports have made
significant strides in implementing the Clean Air Strategy. 
UPDATE ON THE CLEAN AIR STRATEGY 
Trucks 
On March 19, 2009, the Port of Tacoma Commission adopted Resolution 2009-06, establishing
the Port of Tacoma Drayage Truck Emissions Improvement Program, developed to implement
the drayage truck diesel emission reduction goals set forth in the Northwest Ports Clean Air
Strategy. The program also serves as the foundation for future implementation activities. 
On April 14, 2009, the Port of Seattle Commission unanimously authorized the CEO to enter in
to lease negotiations with the Marine Terminal Operators to require implementation of the
Strategy performance measures for trucks, as well as unanimous approval to authorize the CEO
to enter in to an agreement with Puget Sound Clean Air Agency (PSCAA) to transfer up to $2.3
million to support implementation of the Strategy. 
Cargo-Handling Equipment (CHE) 
In late 2008 and early 2009, both Ports were awarded significant grant dollars from EPA and
Washington State to retrofit CHE. The Ports of Seattle and Tacoma will continue to retrofit
CHE working collaboratively with PSCAA, WA Dept. of Ecology, and marine terminal
operators to reach the Strategy's 2010 goal.

Ocean-Going Vessels 
The Ports of Seattle and Tacoma vessel lines have made progress towards reaching the Strategy's
2010 goal for ocean-going vessels, which calls for a switch from high sulfur bunker fuels to
0.5% or less sulfur fuels in auxiliary hotelling engines while at berth. To date, 57% of vessels
that frequently visit the Port of Tacoma to distillate. On March 19, 2009 the Port of Tacoma
Commission recognized Evergreen Line, "K" Line, Maersk Line and Horizon Lines for their
voluntary switch from ship bunker fuel to distillate use at the Port of Tacoma terminals. The
Port of Seattle has partnered with PSCAA on the At-Berth Clean Fuels Vessel Incentive Program
(ABC Program) to provide a $1,500 incentive per call for vessels that meet the 2010 Strategy
goal; in 2008, 31% of frequent calling vessels met the 2010 Strategy goal. 
Reporting 
The Port of Seattle and Tacoma are currently working on the final draft of the first Northwest
Port Clean Air Strategy Implementation Report representing port activities for 2008. This report
is expected to be complete before the end of the second quarter, 2009.
