On December 29, 2010, pursuant to Sections 117(g) and 303(d) of the Clean Water Act, the Environmental Protection Agency (“EPA”) established the Chesapeake Bay Total Maximum Daily Loads (“Bay TMDLs”) for nitrogen, phosphorus, and sediment. The Bay TMDLs apply to the seven watershed jurisdictions: Delaware, Maryland, Pennsylvania, New York, West Virginia, Virginia, and the District of Columbia. TMDLs aim to help restore the Bay by setting pollutant limits on the amounts of nitrogen, phosphorous, and sediment that can enter the Bay without violating water quality standards. The Bay TMDLs plan to reduce nitrogen by 25%, phosphorus by 24%, and sediment by 20% within the Bay watershed. Through the Bay TMDLs, EPA employs measures to ensure accountability and EPA intends to have all pollution control procedures set by the year 2025. For more information about the Bay TMDLs please visit EPA’s Final Chesapeake Bay TMDL website.
