MoreIn a Federal Register notice on Thursday,
Jan. 7, 2011, the EPA officially announced its establishment of the Chesapeake
Bay total maximum daily loads (TMDL) for nitrogen, phosphorus and sediment in
the Chesapeake Bay region and tidal
tributaries.
The agency revised the TMDL after a 45-day public review of its draft, over the autumn months of 2010. Load limits have been established for each of the 92 segments in the tidal portion of the Chesapeake Bay watershed.
The TMDL provides pollutant loads for nitrogen, phosphorus and sediment which can enter a waterbody without causing a violation in the water quality standards. The TMDL allocates that pollutant load between point and nonpoint sources. It contains segment specific point (wasteload) and non-point (load) allocations for nitrogen, phosphorus and sediment that when met will assure the attainment and maintenance of all applicable water quality standards for each of the 92 segments.
The Bay TMDL is a key part of the clean water commitment in the Federal Strategy developed as part of Executive Order 13508 on Chesapeake Bay Protection and Restoration. The EPA has worked closely with its federal partners, the six watershed states, the District of Columbia, local governments and other parties to put in place a comprehensive, transparent and accountable set of commitments and actions that together ensure that pollution controls needed to restore Bay water quality are implemented by no later than 2025, pursuant to Executive Order, 13508.
