The Need for Stakeholder-led TMDL

The Tennessee Department of Environment and Conservation (TDEC) is currently in the process of developing a Total Maximum Daily Load (TMDL) for the Harpeth River. A TMDL is a pollution reduction study and plan that puts a waterbody on the path to restoration. In the case of the Harpeth River, TDEC is engaging stakeholders to help develop limits for phosphorus pollution. CLICK HERE to learn more about the development of a Harpeth River TMDL, the Harpeth Conservancy's concerns and recommendations, and how you can participate in the process.

This page lists resources that provide deeper context for understanding and designing TMDLs in general and stakeholder-led TMDLs in particular.
