Chesapeake Bay TMDL

What's Happening

Jul 6 -
Unanimous Federal Court Decision Upholds Bay TMDL

The 3rd U.S. Circuit Court of Appeals on July 6, 2015 rejected a legal challenge to the Chesapeake Bay TMDL, ruling that EPA’s action is authorized by, and consistent with the Clean Water Act.   In a statement, EPA called the unanimous decision, which affirms a 2013 lower court ruling, “a victory for the 18 million people in the Chesapeake Bay watershed. We can all now as partners continue to build on the progress made in restoring local waters and the Bay.  We remain committed to revitalizing this national treasure through the collaborative federal-state framework with the six Bay states and Washington, D.C.”

Bay TMDL — A Commitment to Clean Water

Actions are being taken across six states and the District of Columbia to reduce water pollution in local streams and rivers in connection with EPA's Total Maximum Daily Load to restore the Chesapeake Bay. Read the Bay TMDL Factsheet (PDF) (2p, 46KB) or view the Bay TMDL Poster (1page, 3.2MB).

The Bay TMDL, a historic and comprehensive "pollution diet," was established in December 2010 based largely on implementation plans prepared by Delaware, District of Columbia, Maryland, New York, Pennsylvania, Virginia, West Virginia.

In 2012, the jurisdictions submitted Phase II implementation plans designed to strengthen the initial cleanup strategies and reflect the involvement of local partners. They also submitted a first set of two-year milestones outlining near-term restoration commitments.

The Bay TMDL is a key part of an accountability framework to ensure that all pollution control measures needed to fully restore the Bay and its tidal rivers are in place by 2025, with practices in place by 2017 to meet 60 percent of the necessary pollution reductions.
