The Texas Commission on Environmental Quality (TCEQ) administers the Texas Clean Fleet Program (TCFP) as part of the Texas Emissions Reduction Plan (TERP). TCFP encourages owners of fleets containing diesel vehicles to permanently remove the vehicles from the road and replace them with alternative fuel vehicles (AFVs) or hybrid electric vehicles (HEVs). Grants are available to fleets to offset the incremental cost of such replacement projects. An entity that operates a fleet of at least 75 vehicles and commits to placing 20 or more qualifying vehicles in service for use in the Clean Transportation Zone may be eligible. Qualifying AFV or HEV replacements must reduce emissions of nitrogen oxides or other pollutants by at least 25% as compared to baseline levels and must replace vehicles that meet operational and fuel usage requirements. Neighborhood electric vehicles do not qualify. For more information, including current application periods, see the TCEQ TERPwebsite. The program is not currently accepting applications (verified July 2019). (Reference Texas Statutes, Health and Safety Code 386 and 392, and Texas Administrative Code 114.650-114.658)
