Chesapeake Bay TMDL

Final EPA Evaluation of 2012-2013 Milestone Progress and 2014-2015 Milestone Commitments in the Chesapeake Bay Watershed

In June 2014, EPA provided its evaluations of the Bay jurisdictions' and federal agencies' progress towards meeting their 2012-2013 milestones. Bay jurisdictions include Delaware, Maryland, New York, Pennsylvania, Virginia, West Virginia and the District of Columbia.

EPA also provided its evaluations of the jurisdictions' and federal agencies' 2014-2015 milestone commitments. The milestones represent key check-in points on the way to having all pollution reduction measures in place by 2025 to restore the Bay and its tidal rivers. By 2017, controls should be in place that would achieve 60 percent of the necessary pollutant reductions.
