RE: December 3'd brieng  Support for Final Northwest Ports Clean Air Strategy 2013 Update.

Dear Mr. Albro:

I am writing to you to urge that the Port of Seattle Commission adopt the Northwest Ports Clean Air
Strategy
(CAS) 2013 Update. As you know, this update establishes new goals, and exible pathways to attain those
goals, that complement and extend the original intent of the 2007 CAS. By adjusting the 2015 goals and
establishing new long-term goals for 2020, the updated CAS will guide efforts to reduce the effects of port
related diesel exhaust on surrounding communities, and reduce port related
green house gases.

The Washington State Department of Ecology (Ecology) has identied diesel fine particles
as one of the air
pollutants most harmful to public health in Washington State. Because of the heavy concentration of diesel
engines and human population at and near ports, cleaning up diesel engines at ports is one of Ecology's top
priorities.  In addition to the impacts of diesel fine particles on human health, the burning of diesel fuel is
a
signicant source of green house gases and the associated environmental, health and economic consequences
of climate change.

Much progress has been made since these efforts began in 2005. The updated CAS builds
on this progress
and importantly adds the reduction of green house gases as one of its major goals.

Ecology has worked with port staff to analyze emissions, focus priorities, develop projects, lend our
technical expertise and provide grant funding for clean diesel projects.  Ecology is committed to continuing
our partnership in implementing the updated CAS.

I would like to thank the Commissioners and Port staff for all their hard work and commitment to cleaning
up the air around ports. There's more work to do and I know we have a devoted and sincere partner in the
Port of Seattle.  Adopting the updated CAS is essential to continue this important collaborative work.

Sincerely,
5am
Stuart A. Clark, Air Quality Program Manager
