Relating to air quality permits for certain concrete plants and crushing facilities.

SB 817 amends Texas Health and Safety Code sections to establish new air quality permit requirements for certain concrete plants and crushing facilities. It prohibits construction within 880 yards of residential areas for facilities performing wet/dry batching or central mixing, and mandates specific pollution controls including enclosed conveying systems, special filters meeting strict emissions standards (no visible emissions exceeding 30 seconds in 5 minutes), and on-site production records for two years. The bill directly affects concrete plants and crushing facilities operating in or near residential zones, requiring them to meet these new environmental standards to obtain or amend permits. These changes aim to reduce air pollution from industrial concrete operations while maintaining operational requirements for affected facilities.
