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 2013: School Bus
Exhaust & Anti-Idling
Retrofits in Idaho
Under the Diesel Emission Reduction Act (DERA) 2013
State Clean Diesel Grant Program, the U.S.EPA West
Coast Collaborative awarded the Idaho Department of
Environmental Quality (IDEQ) $73,431 to install exhaust
and anti-idling retrofits that will reduce diesel school bus
emissions.
What is the Project?
IDEQ will retrofit 7 school buses with closed crankcase ventilation
systems (CCVs) and diesel oxidation catalysts (DOCs), and retrofit
11 school buses with fuel operated heaters to reduce idling and start
up emissions.
Why is this project important?
School bus fleets operate largely in residential areas where children
live and school facilities are located. This program will reduce the
risk from toxic pollutants by reducing the exposure of school-age
children to diesel emissions from school buses. The program area
includes areas of high and medium population density, as well as
small towns in rural areas.
What are the estimated environmental/
economic benefits?
This project will reduce 0.4 tons of particulate matter (PM), 6.6 tons
nitrogen oxides (NOx) and 218 tons of carbon dioxide (C02)
emissions over its operational life. The use of fuel operated heaters
is expected to reduce not only emissions from idling, but start-up
emissions as well. Additional reported benefits of these heaters are
1309 gallons of diesel fuel saved per year, longer engine oil life, less
wear-and-tear on the engine, and relatively easy installation and
maintenance.
How is this project funded?
The West Coast Collaborative is providing $73,431 in funds to
support of this project.
What is the Collaborative?
The West Coast Collaborative (WCC) is an ambitious partnership
between leaders from federal, state, and local government, the
private sector, and environmental groups committed to reducing
diesel emissions along the West Coast, Partners come from all over
Western North America, including California, Oregon, Washington,
Alaska, Arizona, Idaho, Nevada, Hawaii, Pacific Island Territories,
Canada and Mexico. The Collaborative is part of the U.S. EPA
National Clean Diesel Campaign (NCDC). www.epa.gov/cleandiesel
