Conowingo Watershed Implementation Plan (CWIP)
The Chesapeake Bay Program (CBP) partnership’s Principals’ Staff Committee (PSC) agreed to develop a separate and collaborative CWIP that would outline the programmatic and numeric commitments that could be taken to reduce the adverse water quality impacts to the Chesapeake Bay resulting from Conowingo Dam infill, as well as a timeline at which those reductions could be achieved. View the CWIP or learn more about the Steering Committee activities.

The Chesapeake Bay TMDL called for a midpoint assessment to review progress toward meeting the nutrient and sediment pollutant load reductions necessary for Bay restoration. EPA completed this Midpoint Assessment of the Chesapeake Bay Total Maximum Daily Load (PDF)(4 pp, 4 K, About PDF) in 2018. The jurisdictions committed to develop Phase III WIPs following this midpoint assessment. The Phase III WIPs will provide information on actions the jurisdictions intend to implement through 2025 to meet the Bay TMDL restoration goals.
On July 9, 2018, the Chesapeake Bay Program partnership’s Principals’ Staff Committee approved the final Phase III planning targets (PDF) (1 pp, 196 K, About PDF) which represent the nitrogen and phosphorus pollution imits necessary to meet applicable water quality standards in the Chesapeake Bay. The Phase III WIPs will describe the actions the jurisdictions will take to have all practices on the ground by 2025 to achieve their respective Phase III planning targets.
On January 24, 2020, the Chesapeake Bay Program partnership’s Principals’ Staff Committee approved the final Phase III planning targets for sediment which represent the pollution limits necessary to meet applicable water quality standards in the Chesapeake Bay. Additional information on these sediment targets can be found on the Chesapeake Bay Program partnership’s Watershed Implementation Plan (WIP) Sediment Planning Targetsdocument.
