Final TMDLs Approved by EPA: St. Clements Bay

St. Clements Bay Basin is situated approximately 45 km upriver from the mouth of the Potomac River along its northeast shoreline. St. Clements Bay extends about 11 km from its headwaters to the mouth of the river where it discharges into the Potomac River.  The shellfish waters include the tidal waters of the St. Clements Bay Basin and its tributaries in St. Mary's County, Maryland from the headwaters near Dynard, Maryland to its confluence with the Potomac River.  

St. Clements Bay (basin number 02140105) was first identified on the 1996 303(d) list submitted to the EPA by Maryland Department of the Environment (MDE) as being impaired by nutrients, sediments, and bacteria, with listings of biological impacts in non-tidal portions added in 2002. On the draft 2004 303(d) List, specific restricted shellfish harvesting areas were identified. The document available below establishes TMDLs of fecal coliform for identified restricted shellfish harvesting areas in St. Clements Bay.  The nutrient, sediment and biological impairments within the basin will be addressed at a future date.
