Press Room


EPA will establish and oversee achievement of a strict "pollution diet" known as a Total Maximum Daily Load, or TMDL, to remove excess pounds of nitrogen, phosphorus, and sediment harming the Bay and its network of waterways.

  • Each jurisdiction in the 64,000-square-mile watershed – Maryland, Virginia, Pennsylvania, Delaware, New York, West Virginia and the District of Columbia - will get shares of the pollution diet.
  • The Chesapeake Bay TMDL will be supported by a series of accountability measures to ensure that commitments to achieving clean water standards are met.

  • Scheduled for completion in December 2010, the Bay TMDL will be the largest ever developed, yet it will allow states to target cleanup actions to local areas and sources.

  • Actions under the TMDL will complement significant and ongoing work by EPA and its partners to restore the Bay.
