The document summarizes the Chesapeake Bay Total Maximum Daily Load (TMDL) plan, which aims to reduce nitrogen, phosphorus and sediment pollution in the Chesapeake Bay watershed. It outlines that the TMDL caps pollution levels from point sources like wastewater treatment plants and non-point sources like agriculture. States must develop Watershed Implementation Plans by 2017 to show how they will meet pollution reductions through controls on sources. The EPA will take federal actions if states do not meet their pollution reduction targets.
