TMDLs and the Vision for Assessment, Restoration, and Protection Under the Clean Water Act

In 2014, EPA and states began a process to modernize the TMDL program. Like other states, Tennessee submitted a priority framework for TMDLs and TMDL alternatives that Tennessee has committed through 2022. Tennessee has identified subwatersheds (HUC-12s) with source water protection areas and nutrient impaired streams as its priority, and has submitted a list of sixteen such waterbodies to be addressed by 2022. How Tennessee implements the priority goal for TMDL development under the Clean Water Act long-term vision is described in Tennessee’s prioritization framework document.
