The Diesel Emissions Reduction provisions in the Energy
Policy Act of 2005 are a significant funding source to
bring verified and emerging, cost-effective technologies
to communities nationwide.
"Through EPA's Clean Agriculture USA program, we
were able to replace our old, inefficient tractors. The new
tractors are more fuel efficient and burn far cleaner than the
old ones, which were nearly 30 years old. They have made
a significant difference in improving air quality, which helps
our employees and the environment."

Clean Agriculture USA:
Greener Fields and Cleaner Air
Diesel-powered machines help make American farm-
ers among the most productive in the world. During
the last few years, stakeholders representing the
agricultural sector, including agricultural engine and
equipment makers, have been valuable contributors
to the development of new regulations that ensure
new engines will be the cleanest in the world.
There is, however, a legacy fleet of more than
2 million agricultural diesel engines in the fields
today that contribute significant levels of harmful
emissions. They use older diesel engines that pro-
duce exhaust containing ozone-forming nitrogen
oxides (NOX) and particulate matter (PM), or soot, in
addition to other air toxics.
Clean Agriculture USA provides businesses in the
agriculture sector with tools and resources, fund-
ing opportunities, and information regarding best
practices to reduce diesel emissions.
-------
Providing Cleaner Solutions
Clean Agriculture USA helps farmers, agricultural
corporations, equipment manufacturers, and other
related groups reduce diesel emissions from farm
equipment, resulting in cleaner engines and improved
air quality. This program identifies proven strategies to
reduce diesel emissions, including:
Switching to cleaner fuels, such as biodiesel, liq-
uid petroleum gas, and compressed natural gas.
Retrofitting existing diesel equipment with veri-
fied technologies.
Replacing older diesel engines, or entire
machines, with newer, cleaner engines.
Maintaining equipment.
Minimizing idling.
Implementing multi-tillage tools.
Clean Agriculture USA also offers support to help
implement these strategies. For example, Clean
Agriculture USA provides:
Detailed specifications, performance analyses,
and manufacturer data on EPA- and CARB-certi-
fied technologies.
State and local information on funding options
and financial incentives.
Tools and resources, such as emission calculators
and case studies from peers and stakeholders.

Case Studies:
Miami-Dade County Finds Savings With
Repowered Pumps
With funding from the American Recovery and Rein-
vestment Act (ARRA) of 2009, farmers in Miami-Dade
County now have a financial incentive to update
their old irrigation equipment with cleaner pump
engines. The new Tier 3 engines not only produce
fewer emissions but they also use less fuel. By install-
ing the new engines, farmers will reduce average
fuel used by 3 to 6 gallons per hour, saving almost
1,000 gallons of fuel per year. Qualified growers re-
ceive additional savings, with reimbursements from
the county for up to 65 percent of the cost of a new
irrigation pump.
Repowering San Joaquin Agricultural Vehicles
The Air Pollution Control District in San Joaquin
Valley received $2 million to repower 30 off-road
agricultural vehicles with new engines that meet or
exceed EPA's Tier 3 emission standards. Using ARRA
funds, EPA funded this project because of its long-
term economic and immediate health benefits for
the community. The repowered engines are
expected to reduce NOX emissions by more
than 33 tons and PM by more than 1 ton annually.
Through NCDC, EPA provides grants and innova-
tive financing mechanisms to assist eligible partners
in building diesel emission reduction programs.
