Clear Creek Above Tidal: A TMDL Project for Total Dissolved Solids and Chloride

A completed project to develop and implement total maximum daily loads for total dissolved solids and chloride in the freshwater portion of Clear Creek that is above tidal influence.

Counties: Brazoria, Fort Bend, Galveston, Harris
Parameters: chloride, total dissolved solids (TDS)
River Basin: San Jacinto-Brazos Coastal
Segment: 1102

Background

Clear Creek is a suburban freshwater stream located in the southernmost portion of the city of Houston, Texas. Water quality testing has found that concentrations of chlorides and total dissolved solids in Segment 1102, Clear Creek Above Tidal, are not optimum for supporting aquatic life.

The goal of this project is to reduce chloride and TDS in Clear Creek to levels that support a healthy aquatic community.

The goal of a TMDL is to restore the full use of a water body that has limited quality in relation to one or more of its uses. The TMDL defines an environmental target by determining the extent to which a certain pollutant must be reduced in order to attain and maintain the affected use. Based on this environmental target, the state develops an implementation plan to mitigate anthroprogenic sources of pollution within the watershed and restore full use of the water body.

Adopted TMDLs

The commission first adopted these TMDLs on August 10, 2005. The commission adopted revisions to them on April 12, 2006. The EPA approved them on June 26, 2006, at which time they became part of the state's Water Quality Management Plan.

Hot Topic The TCEQ proposes to withdraw these TMDLs in the July 2014 draft Update to the Texas Water Quality Management Plan. The proposal to withdraw is in Appendix III, page 10. Comments are due by September 8, 2014. Find out how to submit your comments.

Updates to TMDLs

From time to time, it is necessary to revise TMDLs to account for changing conditions in the watershed, such as new or amended permits, or urban growth, or to correct oversights in the original TMDL report. Revisions 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.

Revisions to the TMDL are documented in the approved WQMP updates listed below.

Learn more about  WQMP updates and about opportunities to comment on revisions to them.
