DERA Funding Opportunities

 Clean Diesel Grant Program


The U. S. EPA Clean Diesel Program provides support for projects that protect human health and improve air quality by reducing harmful emissions from diesel engines. This program includes grants and rebates funded under the Diesel Emission Reduction Act (DERA).

Authority for clean diesel funding comes from DERA, part of the Energy Policy Act of 2005. As stipulated by the Act

  • Seventy percent of the DERA appropriation is to be used for national competitive grants and rebates.  More inoformation on these national grants can be found at
  • Thirty percent of the DERA appropriation is allocated to the states and territories to fund programs for clean diesel programs. Base funding is distributed to the states and teritories using a formula based on overall partitcipation..

The LDEQ applies for funds from the thirty percent appropriation and makes these funds available to eligible parties, following guidlines established in

EPA awarded the first DERA grants in 2008, the American Recovery and Reinvestment Act (ARRA) grants in 2009, and grants from funds appropriated in Fiscal Years 2009 through 2016.

Project Period

To the extent resources are available, EPA finalizes program awards by October 1 of every year. The LDEQ anticipates that applications for the state DERA funds will be received, evaluated and awarded by the end of the calendar year. All funded projects must be completed by September 30 of the following year.

Please reference the 2022 Applicant Guide for Louisiana Clean Diesel Grant Program for more details on how to apply.

Summary Statement

The LDEQ will award competitive grants to elible organizations for projects that maximize the benefits to public health, create and/or sustain existing jobs, and reduce diesel emissions in Louisiana. Awarded grants will achieve diesel emissions reductions by retrofitting, upgrading, replacing, or reducing idling from on-road and off-road diesel engines and equipment. All projects shall use EPA or California Air Resource Board (CARB) Verified Technologies.

Program Priorities

Project funding for diesel emissions reduction grants will be consistent with  EPA's Program’s priorities in achieving the goals listed below:

  • Public and non-profit organization participation
  • Maximize public health benefits.
  • Cost effectiveness.
  • Create and/or sustain Louisiana jobs
  • Serve areas with the highest population densities or are in poor air quality areas such as ozone non-attainment and maintenance areas.
  • Serve areas with a high concentration of air pollution from diesel engine fleets, including high traffic corridors, ports, rail yards, truck stops, and distribution centers.
  • Maximize the useful life of any certified engine configuration or verified technology.

 LDEQ will commence expenditures and activities as quickly as possible consistent with prudent management when implementing this grant.
