Collectively, the EPA's TMDL and the state Watershed Implementation Plans establish the Clean Water Blueprint for the Chesapeake.

Washington, D.C. and the other six Bay jurisdictions agreed to create state-specific plans to implement 60 percent of their Bay cleanup practices by 2017 and 100 percent by 2025. These plans are called Watershed Implementation Plans or WIPs and will not only help restore the Bay, but will also significantly improve the health of local waterways.
