Relating to contested case hearings on the issuance, renewal, or revocation of authorizations to use certain standard air quality permits.

SB 279 adds a new option for individuals to request a contested case hearing regarding the issuance, renewal, or revocation of certain standard air quality permits. It allows people to challenge these permit decisions if they believe the action conflicts with the relevant state law, but only for permit applications filed on or after September 1, 2025. Applications filed before that date continue to follow the existing rules. The bill does not change the standard permit process itself but provides a specific hearing mechanism for new applications under the new rules. This directly affects businesses or individuals seeking or challenging these air quality permits in Texas.
