Relating to programs established and funded under the Texas emissions reduction plan.

HB 3868 amends Texas law to expand funding for existing air quality programs under the Texas Emissions Reduction Plan. It directs the state commission and comptroller to provide grants for specific initiatives, including clean school buses, alternative fuel vehicle programs, diesel emissions reduction projects, and port authority incentives in areas with poor air quality. The bill specifically authorizes funding for programs like the Texas clean fleet program, hydrogen infrastructure grants, and congestion mitigation projects. These funds support local entities and agencies working to reduce emissions of nitrogen oxides, particulate matter, and ozone precursors. The bill does not create new programs but modifies how existing state-funded environmental initiatives are financed.
