Total Maximum Daily Loads and Implementation Plans

 
     

What is TMDL?

Total Maximum Daily Load (TMDL) is like a budget for pollution. The Clean Water Act and the EPA require that all states identify water bodies that do not meet, or are not expected to meet, applicable water quality standards for designated uses. These water bodies are listed and prioritized in order to schedule TMDL development. A TMDL study is a technical analysis that determines maximum loadings of a pollutant of concern that a water body can receive and still meet water quality standards and allocates this allowable loading to point and nonpoint pollutant sources in the watershed. Visit the Texas Commission on Environmental Quality (TMDL) website to learn more about TMDLs.

Get Involved! Participate in Specific TMDL Projects in the Region

H-GAC hosts open houses and public meetings to let people know about and participate in specific TMDL projects in the region. Local perspectives and involvement are a key part of any TMDL. More information on our regional projects can be found on the TCEQ Website.

The Bacteria Implementation Group: A plan to reduce bacteria  levels in waterways for 72 TMDLs in the Houston-Galveston Region, including Buffalo and Whiteoak Bayous, Clear Creek, waterways upstream of Lake Houston, and other bayous and streams in the Houston metro area.
