South Carolina Diesel Emissions Reduction Act (DERA) Grants

Reducing diesel emissions is an important air quality challenge as diesel emissions make up a significant portion of the on-road and nonroad mobile source air pollution in South Carolina. Although more stringent emission standards are taking effect for new heavy-duty on-road and nonroad engines, the diesel engines currently in use will last a long time and continue to emit large amounts of air pollution for years to come.

The U.S. Environmental Protection Agency (EPA) administers four components of the DERA grants through its National Clean Diesel Campaign:

State Clean Diesel Grant Program funded through DERA has provided an opportunity to help reduce diesel emissions. The federal funding for the State Clean Diesel Grant Program funds projects that provide cost-effective diesel emission reduction strategies. This funding is intended for county, city, or other local government entities, private organizations, businesses, and universities. Grants are awarded to eligible applicants for implementation of diesel emission reduction projects across the state to achieve public health and air quality goals.

The National Clean Diesel Funding Assistance Program awards competitive grants to fund projects that implement EPA or CARB verified and certified diesel emission reduction technologies.

The National Clean Diesel Emerging Technologies Program awards competitive grants for projects that spur innovation in reducing diesel emissions through the use, development and commercialization of emerging technologies. Up to 10 percent of the national funds may be spent on emerging technologies.

SmartWay Clean Diesel Finance Program issues competitive grants to establish national low-cost revolving loans or other innovative financing programs that help fleets reduce diesel emissions.

Please visit the Southeast Diesel Collaborative's website for more information on these grant opportunities and clean diesel strategies. This group 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.
