Chesapeake Bay TMDL

Chesapeake Bay TMDL Midpoint Assessment

The Chesapeake Bay TMDL document calls for an assessment in 2017 to review progress toward meeting the nutrient and sediment pollutant load reductions necessary for Bay restoration. This midpoint assessment will measure the Bay jurisdictions' progress towards meeting the 2017 goal of having practices in place to achieve 60 percent of the necessary reductions compared to 2009 levels. The Bay jurisdictions include Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia.

The ultimate goal is to have all practices and controls in place by 2025 to achieve the Bay's dissolved oxygen, water clarity/submerged aquatic vegetation and chlorophyll-a standards.

As part of this midpoint assessment, the Chesapeake Bay Program (CBP) partnership is reviewing the latest science, data, modeling and decision support tools used to measure progress. The intent of this part of the midpoint assessment is to strengthen the CBP partnership's decision support capabilities to optimize the jurisdictions' Phase III Watershed Implementation Plans (WIPs).

The Phase III WIPs will provide information on what actions the jurisdictions intend to implement between 2018 and 2025 to meet the Bay TMDL restoration goals.
