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) Exitwhich 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 Targets Exitdocument.
