  • New Fact Sheet Helps Chesapeake Bay States Design Nutrient Trading Programs

    2011 will be an important year for the Chesapeake Bay, not only because scientists are predicting an unusually bad “dead zone” this summer.

    Last December, the Environmental Protection Agency (EPA) issued total maximum daily loads (TMDLs) that establish the amount of nutrient and sediment pollution that the Bay and its tidal tributaries can safely receive each year. The TMDLs divide the pollution loads among sources, such as urban areas regulated for stormwater runoff, wastewater treatment plants, and agricultural lands.

    Now, responsibility for implementing the TMDLs falls to states in the Bay watershed that have been delegated authority from EPA to run water quality programs. By December 1, 2011, Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia will submit plans to EPA that explain how sources within their jurisdiction will meet and maintain the TMDLs.

    The December deadline has states reviewing legislation and regulations that could reduce the amount of nutrient and sediment pollution that impairs Bay water bodies.
