Overview and Goals
The goal of this current project is to reduce bacteria levels in parts of the San Antonio River, making them safer for recreation. High levels of bacteria may pose a risk to people who swim or wade in them—activities called “contact recreation” in the state's standards for water quality.
The stream segments included in the project are Salado Creek (Segment 1910), Walzem Creek (Segment 1910A), and the Upper San Antonio River (Segment 1911). Texas AgriLife Research and the San Antonio River Authority (SARA) are key partners in this project.
In all our projects, we seek opinions and information from stakeholders—people who represent government, permitted facilities, agriculture, business, environmental, and community and private interests in the watershed.
All stakeholders are welcome to get involved in developing the strategy to improve water quality. Public meetings about the project are open to everyone. Find out more about what it means to participate in TMDL projects.

At this meeting, stakeholders will discuss adding more TMDLs for the project watershed.
Implementation Plan Development
Texas AgriLife is coordinating with people in the watershed to develop the I-Plan. A coordination committee representing diverse interests will develop the plan.
Everyone is welcome to participate in this project to improve the river. Meetings about the project are open to anyone interested.
Technical Subcommittee, continued
The TCEQ and Texas AgriLife are working with stakeholders to develop an I-Plan for the project watersheds.
- I-Plan Summary Facts (June 2013)
The I-Plan will complement the watershed protection plan (WPP) for the Upper San Antonio River. The WPP, now being updated, was originally developed by SARA in 2007, together with stakeholders, the City of San Antonio, Bexar County, and other partners. The WPP was developed to allow early implementation of measures to reduce pollution; environmental improvement targets were based on data and information in the TMDL report. on the SARA website.
The commission adopted these TMDLs on July 25, 2007. The EPA approved them on September 25, 2007, at which time they became part of the state's Water Quality Management Plan.

Revisions to the 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. Revisions are made to TMDLs in one of two ways:
- Updates are made to account for changing conditions in the watershed, such as new or revised wasteload allocations, permits that have been canceled or have expired, or changed facility names.
- Addenda are created to add load allocations for assessment units that are impaired by the same pollutant or condition, within the same watershed as in the original TMDL report.
Updates to TMDLs
Updates to the load allocations in TMDLs are made via the state’s 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.
Updates to the TMDL are documented in the approved WQMP updates listed below.

- July 2014, Appendix VI, page 39
- April 2009, Appendix III, pages 18-19
- April 2010, Appendix IV, pages 19-20
Meeting Records, TMDL Development
A stakeholder committee called the San Antonio Bacteria TMDL Advisory Group assisted the TCEQ in developing the TMDLs. The group included volunteer members who represented government, permitted facilities, agriculture, business, environmental, and community interests.
