What SACE Is Doing about Diesel Pollution


SACE is part of the Diesel Clean Up Campaign, a diverse partnership of over 500 environmental, health, faith and industry organizations. The partnership works to reduce direct diesel fine particulate matter and black carbon emission from heavy-duty diesel engines.

SACE also works with the Southeast Diesel Collaborative, which is part of EPA’s National Clean Diesel Campaign, a program combining regulatory measures with voluntary initiatives to reduce the pollution emitted from diesel engines across the country. The collaborative is a partnership between leaders from federal, state and local government, the private sector and other stakeholders in Alabama, Florida, Georgia, Kentucky, Mississippi, North Carolina, South Carolina and Tennessee. The goal of the collaborative is to improve air quality by encouraging the use of clean, renewable energy and by reducing diesel emissions from existing engines and equipment from agriculture, heave construction and on-road sectors.

Across the region, SACE has worked to help fleets identify funding options for retrofit projects and we encourage diesel fleets to retrofit their vehicles with pollution control devices and to use clean fuels, such as ultra-low sulfur diesel in fleets that are currently not federally required (off-road), and biodiesel blends. These changes could help cut diesel emissions by up to 90 percent, thus preventing premature deaths every year and significantly reducing the number of respiratory illnesses suffered by children and other sensitive people.

Clean Contracting
Clean contracting includes performance standards that require and/or encourage contractors, owners and operators of construction and off-road diesel equipment to reduce emissions by installing pollution control devices. These standards can also include idling reduction parameters, use of clean fuels, and/or properly maintaining equipment. These standards can be established and implemented by and for state government, city and county government fleets or those that perform public work or by private companies.

Encourage and require the use of biodiesel by all diesel fleets
Biodiesel blends, like B20, can reduce particulate matter by12-15%. Further, biodiesel can provide the needed lubricity for ultra-low sulfur diesel fuels currently used in on-road diesel vehicles. SACE encourages the use of biodiesel for all diesel fleets.

Encourage and require the use of ultra-low sulfur diesel fuel in off-road fleets.
Ultra-low sulfur diesel fuel is currently required by EPA for use in all on-road diesel engines. Regulations for the use of ULSD in non-road engines are being phased in from 2010 to 2014. SACE encourages the early use of ULSD in off-road vehicles. Use of the fuel now can bring air quality improvements sooner.

  • The Congestion Mitigation and Air Quality Improvement (CMAQ) program passed as part of the 2012 federal Transportation bill (MAP-21) allows for non-attainment areas to use funding to retrofit or replace diesel construction equipment used in federally funded transportation project in order to reduce the emissions from the projects. The clean up of these engines will significantly help reduce the public health burden and climate impacts of these programs. Implementation guidance on the this program is now available.

  • The 2012 Diesel Emissons Reduction Act awards have been announced. EPA awarded $30 million to clean up diesel engines across the U.S. To learn about the project’s funded, visit EPA’s website here. Congratulations to the Southeast awardees: Alabama State Ports Authority and the SC Department of Health and Environmental Control.
