S.B. No. 1145 amends the Texas Water Code to grant the Texas Commission on Environmental Quality (TCEQ) the authority to issue permits for the land application of produced water from certain mining and oil and gas extraction operations. The bill modifies Section 26.131 by adding a new Subsection (e) that allows TCEQ to issue these permits for treated produced water, while also mandating the adoption of standards to prevent pollution of surface and subsurface water. Additionally, it clarifies that the Railroad Commission of Texas retains the authority to issue permits for waste discharge, with the new provisions taking effect only for applications filed after the bill's effective date.

The bill specifies that the changes will apply to permits filed on or after September 1, 2025, ensuring that applications submitted before this date will be governed by the existing law. This legislative change aims to enhance the management of produced water in Texas, promoting beneficial use while safeguarding environmental quality.
