Sunset Laws - As enacted, extends the air pollution control board to June 30, 2031. - Amends TCA Title 4, Chapter 29 and Title 68, Chapter 201, Part 1.

HB 230 extends the existence of Tennessee's air pollution control board until June 30, 2031, preventing it from automatically ending under sunset provisions. The bill updates two sections of Tennessee law (Title 4, Chapter 29 and Title 68, Chapter 201) to clarify the board's legal foundation and ensure its continued operation. This change directly affects how air pollution regulation is governed in Tennessee, maintaining the board's authority to oversee emissions standards and enforcement. The bill does not create new environmental rules but preserves the existing structure for air quality management. (Note: The bill became law on March 21, 2025.)
