The South Carolina Department of Environmental Services (SCDES) announced Monday that it is accepting applications for the Diesel Emissions Reduction Act (DERA) grant program

SCDES says $400,000 is available to fund projects that reduce diesel emissions and improve air quality.

Department leaders say the initiative aims to assist local governments, non-profits, and private businesses in upgrading or replacing older, high-emission diesel equipment.

“Diesel engines last a long time, and many older-model diesel engines are still in use throughout our state. Older engines have significantly higher emissions than similar, newer engines,” said Rhonda Thompson, Chief of SCDES’s Bureau of Air Quality.

Funds can be used for different projects, including:

  • Replacing older diesel vehicles and equipment.
  • Retrofitting engines with cleaner technology.
  • Installing idle-reduction technologies.

Past projects have upgraded school buses and replaced concrete trucks.

The grants typically cover approximately 25% of total project costs. Applicants are responsible for the remainder.

Applications for the grant can be completed online. Applications are due June 12.
