Chesapeake Bay TMDL

EPA Evaluation of Final Phase III WIPs

EPA Evaluates Final Phase III Watershed Implementation Plans– EPA has released its evaluations of final Phase III Watershed Implementation Plans (WIPs) from Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia, and the District of Columbia to reduce nitrogen, phosphorus and sediment pollution to the Chesapeake Bay.  As part of the implementation of the Chesapeake Bay TMDL, jurisdictions committed to develop WIPs that document how jurisdictions will achieve and maintain water quality standards.   The third and final phase of implementation called for the development of Phase III WIPs which provide information on actions the jurisdictions intend to implement between 2019 and 2025 to meet the goals of the Chesapeake Bay TMDL.  The seven jurisdictions released their final Phase III WIPs on August 23, 2019. 

To get answers to state-specific questions, please visit your state's website or contact your WIP lead.
