TX SB273

Requires the Texas Commission on Environmental Quality (TCEQ) to consider cumulative effects on public health and physical property from air contaminant emissions when determining whether to issue new air quality permits

Mandates that permit decisions account for combined emissions from both the facility seeking a permit and all other facilities located within three miles of the site

Adds cumulative emissions impact assessment as a required consideration for preconstruction permit renewals, alongside existing criteria like operator performance and emission control equipment effectiveness

Applies only to permit applications filed with TCEQ on or after September 1, 2025; applications filed before that date remain subject to prior law
