What Is TMDL? (Total Maximum Daily Load)

    A TMDL is a technical analysis that determines the maximum loading of the pollutant of concern a water body can receive and still both attain and maintain its water quality standards, and allocates this allowable loading to pollutant sources in the watershed.  Upon approval by the Commission, this technical analysis must be submitted to EPA for review and approval.

    TMDL stands for Total Maximum Daily Loads. These projects evaluate stream and lake segments, ultimately determining the amount of pollutant which can be contributed by both point and non-point sources.  The TMDL Program works to improve water quality in impaired or threatened water bodies in Texas. The program is authorized by and created to fulfill the requirements of Section 303(d) of the federal Clean Water Act.

    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 and, based on that target, the state develops an implementation plan to mitigate anthropogenic (human-caused) sources of pollution within the watershed and restore full use of the water body.
