Chesapeake Bay TMDL Development and Regulatory Dates


On December 29, 2010, the Environmental Protection Agency (EPA)  issued the final Total Maximum Daily Load (TMDL) for the Chesapeake Bay.  The TMDL identifies the necessary pollution reductions of nitrogen, phosphorus and sediments necessary to restore life to our local waterways and the Chesapeake Bay. The TMDL is designed to ensure that all pollution control measures needed to fully restore the Bay are in place by 2025, with at least 60% of the actions being completed by 2017.  That is only 6 years away.

Because Pennsylvania revised its draft Watershed Implementation Plan to include a significantly increased commitment to enforcement and compliance with state requirements for agriculture and funding to develop and implement state-of-the art technologies for converting animal manure to energy for farms, EPA has reduced or removed most federal backstops, for now, which would have concentrated mostly on wastewater treatment plants, municipal stormwater systems and large
animal agricultural operations in the watershed.

EPA will now shift its focus to Pennsylvania, and the other Chesapeake Bay watershed states, to monitor the implementation of the state's Nov. 29, 2010, Watershed Implementation Plan's policies and programs that will reduce pollution on the ground and in the water.  There will be two year milestones established and monitored.  If progress is insufficient, EPA has said it will take appropriate contingency actions including targeted compliance and enforcement activities, expansion of requirements to obtain NPDES permit coverage for currently unregulated sources, revision of the TMDL allocations and additional controls on federally permitted sources of pollution, such as wastewater treatment plants, large animal agriculture operations and municipal stormwater systems.

In 2011, Pennsylvania will continue to implement the state Watershed Implementation Plan as well as develop Phase II of the Watershed Implementation Plan. designed to engage local governments, watershed organizations, conservation districts, citizens and other key stakeholders in reducing water pollution.
