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.

SB 51 extends the Tennessee Air Pollution Control Board's existence until June 30, 2031, by amending two sections of Tennessee law (TCA Title 4, Chapter 29 and Title 68, Chapter 201, Part 1). It removes an outdated reference to an automatic expiration and clarifies the board's legal foundation under existing statutes. This change ensures the board can continue regulating air pollution without requiring new legislation before 2031. The bill directly affects the board and the state's environmental oversight process.
