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 2020: Northwest
Seaport Alliance - Electrical
Terminal Tractors Project

Under the Diesel Emission Reduction Act (DERA), the
U.S. Environmental Protection Agency (EPA) awarded
the Northwest Seaport Alliance a $782,482 grant with
Fiscal Year 2020 funding. This grant will fund the
replacement of six (6) diesel tractors with six (6) fully
battery-electric, zero emission, terminal tractors,
supporting reduced emissions and improved air quality in
Tacoma, Washington. The project will be implemented
with a cost share of $956,367 and $16,224 in additional
leveraged funds for a total project cost of $1,755,073.

What is the Project?

The Northwest Seaport Alliance will purchase six (6) fully battery-
electric, zero emission, terminal tractors, charging units, and
charging pedestals to replace six (6) existing diesel tractors that are
a mix of Tier 2 and Tier 3 nonroad diesel engines. These pieces of
port cargo handling equipment operate at the South Intermodal Yard
Facility moving containerized cargo to and from railcars. This project
will contribute to achieving the emissions reductions goals the NWSA
has set via the Northwest Ports Clean Air Strategy (NWPCAS) for
reducing air pollutants and greenhouse gas emissions, and improved
air quality within the Tacoma-Pierce County PM2.5 maintenance
zones.

Why is this Project Important?

In the EPA's 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 2020 National Priority
Area list. This electrical terminal tractors project will result in
reductions of diesel particulate matter emissions at the Port of
Tacoma, helping the region to remain in attainment of the federal
standards. This project maximizes health benefits by reducing diesel
emissions generated in the movement of goods in Tacoma's
commercial and port district, an area that is disproportionately
impacted by emissions from diesel fleets.

What are the Estimated Environmental
Benefits?

The replacement of these diesel terminal tractors with battery electric
equipment is projected to reduce the annual diesel emissions from by
5.37 tons of nitrogen oxides (NOx), 1.41 tons of particulate matter 2.5
(PM2.5), 0.43 tons of hydrocarbons (HC), 3.26 tons of carbon
monoxide (CO), and 259 tons of carbon dioxide (CO2), as well as
reduce annual fuel consumption by 22,998 gallons. This will result in
estimated cumulative emission reductions of 32.21 tons NOx, 8.44
tons PM2.5, 2.56 tons HC, 19.57 CO, and 1,552 tons CO2, over the
lifetime of these vehicles.

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:
