News from the Texas TMDL Program
News announcements including proposed TMDLs or I-Plans for public comment, adopted TMDLs or approved I-Plans, and training opportunities.
The TMDL Program sets targets for improved quality in surface waters. Communities in the watersheds work together to develop implementation plans (I-Plans) to achieve those targets.
Adopted TMDLs
The Commission adopted Two TMDLs for Indicator Bacteria in the Halls Bayou Tidal and Willow Bayou Watersheds on July 23, 2025. Read more about this project on the Halls Bayou and Willows Bayou project page.
Approved I-Plans
Community stakeholders worked together to create Implementation Plans for three TMDL projects. The Commission approved the I-Plans on July 9, 2025 for:
Revisions to TMDLs
From time to time, it is necessary to revise TMDLs to account for changing conditions in the watershed. Revisions to the load allocations in TMDLs are made via the State’s Water Quality Management Plan (WQMP), which is updated quarterly.
The WQMP provides projected effluent limits for use in planning and permitting activities under the Texas Pollutant Discharge Elimination System (TPDES). The TCEQ reviews all applications for new and amended permits for conformance with applicable portions of the WQMP, including adopted TMDLs.
Information about how to view and comment on the latest draft WQMP Update will be posted on this page quarterly, so check back here for more details!
