The goal of the Collaborative is to leverage federal funds to strategically reduce emissions from the most polluting diesel sources in impacted
communities. The Collaborative seeks to improve air quality and public health by targeting the highest polluting engines with the most cost-effective
control strategies.

DERA 2021: Northwest
Seaport Alliance - Husky
Terminal Shore Power
Expansion

Under the Diesel Emission Reduction Act (DERA), the
U.S. Environmental Protection Agency (EPA) awarded
the Northwest Seaport Alliance a $1,000,000 grant with
Fiscal Year 2021 funding. This grant will fund the
expansion of a shore power system at Husky Terminal
supporting reduced emissions and improved air quality in
Tacoma, Washington. The project will be implemented
with a cost share of $3,000,000 and $157,312 in
additional leveraged funds for a total project cost of
$4,157,402.

What is the Project?

The Northwest Seaport Alliance (NWSA) will expand a container ship
shore power project at Husky Terminal in Tacoma, WA that will
increase the electrical capacity of the planned system and add a third
connection point at each berth. The expansion will ensure that the
shore power system has maximum flexibility and efficacy. These
improvements will also allow the system to accommodate a broader
range of vessel energy loads and increase the number of vessel
configurations that allow shore power connections. This is expected
to significantly increase utilization of the shore power system,
delivering additional emission reductions and associated clean air,
climate, public health, and environmental justice benefits.

Why is this Project Important?

In EPAs 2014 National Air Toxics Assessment, Pierce County,
Washington was identified as an area where all or part of the
population is exposed to diesel particulate matter concentrations
above the 80th percentile and is on the EPA 2021 National Priority
Area list. In the Tacoma/Seattle area, diesel exhaust presents the
greatest public health risk of all toxic air pollutants. The
neighborhoods surrounding Husky Terminal are disproportionately
impacted by air pollution due to their proximity to the port industrial
complex and the I-5 corridor. In the Hilltop and East side
neighborhood census tracts closest to the port, the percentage of the
population below the poverty line is also more than double the Pierce
County and state-wide totals. This project would reduce the diesel
pollution load on all communities near the port industrial complex,
maximizing health benefits and addressing environmental justice
concerns.

What are the Estimated Environmental
Benefits?

The expansion of the shore power system is projected to reduce the
annual diesel emissions by 52.8 tons of nitrogen oxides (NOx), 0.88
tons of particulate matter 2.5 (PM2.5), 0.78 tons of sulfur oxides
(SOx), and 2,632 tons of carbon dioxide (CO2), as well as reduce
annual marine fuel consumption by 2,017 metric tons. This will result
in estimated cumulative emission reductions of 1,584 tons NOx, 26.4
tons PIVk.s, 23.4 tons SOx, and 78,960 tons CO2.

How is this Project Funded?

The West Coast Collaborative is a partnership between leaders from
federal, tribal, state, and local government, the private sector, and
environmental groups committed to reducing diesel emissions along
the West Coast and is part of the National Clean Diesel Campaign:
