^ pubic-private partnership to reduce diesel emissions

www.westcoastcollaborative.org

The West Coast Collaborative is a public-private partnership focused on reducing diesel emissions throughout western North America and the U.S.
Pacific Islands. The Collaborative seeks to significantly improve air quality and public health by providing assistance to upgrade high-polluting diesel
engines, vehicles and equipment with cost- effective emission control technologies.

What is the Collaborative?

The West Coast
Collaborative is a
partnership among
leaders from federal,
tribal, state, and local
governments, the private
sector and environmental
and community groups in
EPA Regions 9 and 10.

The West Coast Collaborative is pleased to announce the Maricopa County
Air Quality Department's (MCAQD's) receipt of a U.S. Environmental
Protection Agency (U.S. EPA) Diesel Emissions Reduction Act (DERA) State
Grant to replace legacy diesel school buses and heavy-duty trucks in
Arizona. This project will be implemented using $525,392 in DERA grant
funding combined with $350,261 in matching funds and $1,745,550 in cost-
share funds from participating fleets.

What is this Project?

This project will replace: 1) six legacy diesel school buses with model year
2021+ alternative fuel buses; 2) one legacy diesel school bus with model
year 2021+ battery-electric bus; and 3) nine Class 6-8 legacy diesel trucks
with model year 2021+ diesel trucks. The older, replaced vehicles will be
removed from service and permanently destroyed.

Why is this Project Important?

Exposure to diesel exhaust is associated with decreased lung function and
can also exacerbate the symptoms of asthma, bronchitis and pneumonia. By
partnering with school bus and trucking fleet operators to replace high-
emitting, legacy heavy-duty diesel vehicles with modern clean diesel and
alternative fuel technologies, this project reduces human exposure to diesel
emissions and therefore negative health effects associated with diesel
exposure. Expected unquantifiable benefits of the project include
increased awareness of the need to improve air quality, particularly
among Arizona.

Who are the project Partners?

The project will be led by MCAQD, a local agency whose mission is to provide
clean air to Maricopa County residents and visitors. MCAQD received the DERA
grant award through the WCC and will distribute the grant funds to
participating fleet operators: Yuma Union High School District, Madison School
District, Sysco Foods, and White Water II, LLC. MCAQD will be responsible for
data monitoring and reporting for the project.
