The TMDL Program works to reduce pollution in impaired or threatened waterways in Texas. A TMDL is like a budget—determining how much of a particular pollutant a water body can assimilate without its quality being impaired.
While a TMDL analysis is being completed, stakeholders and other state agencies begin developing an implementation plan (I-Plan) with the steps necessary to improve water quality.
