About the Heavy Duty Diesel Replacement Program

The Houston-Galveston Area Council’s Drayage Program has been replaced by the Heavy Duty Diesel Replacement Program (HDDRP). Grant funds are available, and we are accepting new applications.

The H-GAC Heavy Duty Replacement Program provides a reimbursement grant to help fund the replacement of heavy duty diesel powered equipment with newer, cleaner equipment.

Funding Limits

The amount of the reimbursement grant is limited to:

  • 50% of the incremental cost of the equipment should the new equipment be powered by diesel fuel.
  • 75% of the incremental cost of the equipment should the new equipment be powered by alternative fuel (such as CNG, LNG, Electric, etc.).

The incremental cost is the price of the equipment less all taxes, fees, and funds generated through the vehicle/equipment dismantling process.

  • On-road vehicles class 6 to class 8 are eligible.
