The National Diesel Emissions Reduction Program provides funding through its two components:

National Clean Diesel Program (70% of funding)

• National Clean Diesel Funding Assistance Program contains the majority of the funding dedicated to deployment of EPA-verified and certified technologies. This component will be administered by EPA"s regional offices.
  
  
• National Clean Diesel Emerging Technologies Program fosters the deployment of innovative technologies through a national grant competition. To qualify as an emerging technology, a manufacturer must have an EPA approved application and test plan for verification.

• SmartWay Clean Diesel Finance Program allows EPA to issue competitive grants to establish national low-cost revolving loans or other financing programs that will provide funding to fleets to reduce diesel emissions.

State Clean Diesel Grant Program (30% of funding) makes funds directly available to States interested in establishing new diesel emission reduction programs.
