The TMDL Program works to improve water quality in impaired or
threatened water bodies in Texas. These projects have been adopted
by the TCEQ and submitted to the Environmental Protection Agency
(EPA) for review. Final approval from EPA may be pending.
A TMDL and its implementation plan are developed to restore the
full use of a water body that has limited quality in relation to
one or more of its uses. One TMDL is required for each impairment
listed in each water body.
An impairment is the combination of the use that is affected
(such as support of aquatic life) with the pollutant or condition
of concern (such as selenium or low dissolved oxygen). For example,
if Jones Creek was listed as not attaining the aquatic life use
because of low dissolved oxygen concentrations, and not attaining
the fish consumption use because of selenium in fish tissue, two
TMDLs would be required for Jones Creek (one for dissolved oxygen
and one for selenium).
