The 2010 Chesapeake Bay Total Maximum Daily Load (Bay TMDL) is in place to ensure the Bay and its tidal rivers maintain a healthy water quality by setting limits on the amount of nutrients (nitrogen and phosphorus pollution) and sediment that flow into it. Each of the six watershed states – Delaware, Maryland, New York, Pennsylvania, Virginia and West Virginia – and the District of Columbia recently developed roadmaps called Phase III Watershed Implementation Plans (WIPs) to guide them in meeting their pollutant reduction goals by 2025. Sediment allocations under the Bay TMDL were established differently than those for nutrient pollutants due to scientific evidence supporting the greater importance of reducing nitrogen and phosphorus loads entering the Bay.
