## **What is the Bay TMDL?**

On December 29, 2010, the U.S. Environmental Protection Agency established the Chesapeake Bay Total Maximum Daily Load (TMDL). The TMDL is a historic and comprehensive "pollution diet" to restore clean water in the Chesapeake Bay and the region's streams, creeks, and rivers.

## Implementing the TMDL

A number of elements are in place to ensure that all pollution control measures needed to fully restore the Bay and its tidal rivers are in place by 2025. Practices will also be in place by 2017 to meet 60 percent of the necessary pollution reductions.
