Relating to the denial of certain applications for a permit or other authorization under the Texas Clean Air Act on the basis of certain adverse impacts.

SB 2636 requires the Texas Commission on Environmental Quality to deny permits for new facilities under the Texas Clean Air Act if emissions would disproportionately harm the health, property, or environment of nearby low-income communities compared to other populations. The bill mandates that the commission consider both the individual facility's impact and the cumulative effect of multiple facilities in the area on low-income residents. This applies only to permit applications filed on or after September 1, 2025, with prior applications governed by existing law. The policy change directly affects developers seeking new facility permits in communities with significant low-income populations.
