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 TMDLs are documented in the approved WQMP updates listed below. Files are in PDF.
- March 2008, pages 12-13
- June 2009, Appendix II, pages 16-17
- December 2009, Appendix I, page 13
- September 2011, Appendix II, page 13
