Relating to the addition of certain counties to the Texas Emissions Reduction Plan.

HB 2179 expands Texas' Emissions Reduction Plan by adding 24 specific counties to the list of "affected counties" under state law. The bill amends the Health and Safety Code to include counties like Travis (Austin), Bexar (San Antonio), Williamson, and others, plus a provision for future counties designated due to poor air quality. This change directly affects residents and businesses in these counties, as they will now fall under the plan's requirements for reducing air pollution. The bill takes effect September 1, 2025, without altering existing emissions standards.
