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. Specifically, the bill modifies Section 26.131 by adding Subsection (e) and Subsection (d) to allow the TCEQ to issue permits for the land application of treated produced water, while ensuring that such applications adhere to established water quality standards. The bill emphasizes the importance of preventing pollution of surface and subsurface water through the adoption of relevant standards by the commission.

The changes made by this Act will only apply to permit applications filed on or after its effective date of September 1, 2025. Applications submitted before this date will continue to be governed by the existing laws in effect at the time of filing. This legislative update aims to enhance the management of produced water in Texas, promoting beneficial use while safeguarding environmental quality.
