Phase III Watershed Implementation Plans

In 2010, the Chesapeake Bay Total Maximum Daily Load (TMDL) was established by the U.S. Environmental Protection Agency (EPA). This historic clean-up plan provides a guide for reducing pollution and restoring clean water to the Chesapeake Bay and its local rivers and streams.

To guide these efforts, Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia (collectively referred to as the “Bay jurisdictions”) created a series of roadmaps—known as Watershed Implementation Plans, or WIPs—describing how each will achieve the pollution reductions called for in the TMDL.

There are three phases of WIPs. Phase I and II WIPs were developed in 2010 and 2012, respectively, and describe actions to be implemented by 2017 and 2025 to achieve the goals of the TMDL. Phase III WIPs, under development in the 2017 to 2018 timeframe, will describe actions the seven Bay jurisdictions intend to implement through 2025 to meet Bay restoration goals, based on a 2017 midpoint assessment of progress.
