Relating to standard permits for certain concrete plants.

SB 1178 modifies permit requirements for concrete plants in Texas that perform wet batching, dry batching, or central mixing. It requires applicants to submit detailed operational plans, including daily facility and vehicle operation hours (7 a.m. to 7 p.m. for facilities, 5 a.m. to 9 p.m. for transport), and site maps showing property boundaries and emissions points. The bill allows limited exceptions for up to five days yearly for special circumstances or emergencies, but mandates on-site record-keeping for any alternative hours used. Existing permits under this section are exempt from the new operating hour rules, and the bill takes effect September 1, 2025.
