The TMDL examines the possible sources of pollution and determines a pollutant reduction target. The I-Plan, developed by stakeholders, outlines how they plan to reduce pollution and restore water quality.

Implementation Plan

The commission approved the implementation plan on February 9, 2011.

TMDL

The commission adopted this TMDL on August 8, 2007.

The EPA approved the TMDL on April 21, 2009, at which time it became part of the state’s Water Quality Management Plan.

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.

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