Final West River PCB TMDL page

Final TMDLs Approved by EPA: West River and Rhode River

The West and Rhode Rivers are located in Anne Arundel County, Maryland, on the Western Shore of the Chesapeake Bay. The West River is approximately 4 miles in length, with a watershed area of approximately 19,865 acres (80 square kilometers). Rhode River, one major tributary with a length about 4 miles, connects to the mouth of West River. 

Maryland's water quality standards specify that all surface waters of the State shall be protected for water contact recreation, fishing, and the protection of aquatic life and wildlife. The designated use of the tidal portion of the West River 8-digit basin which includes the Rhode River watershed (Basin Code: 02131004) is Use II – Support of Estuarine and Marine Aquatic Life and Shellfish Harvesting. The Maryland Department of the Environment (MDE) has identified the tidal portion of the West River 8-digit basin which includes the Rhode River watershed (Integrated Report Assessment Unit ID: MD-WST-RHDMH-02131004) on the State’s 2012 Integrated Report as impaired by PCBs in fish tissue (2006). The Maryland Department of the Environment (MDE) has identified the waters of the West River Mesohaline Chesapeake Bay Segment (Integrated Report Assessment Unit ID: MD-WSTMH) on the State's 2012 Integrated Report as impaired by nutrients (nitrogen & phosphorus) (1996 & 2012), total suspended solids (1996), and fecal coliform (1996). MDE has identified the waters of the Rhode River Mesohaline Chesapeake Bay Segment (Integrated Report Assessment Unit ID: MD-RHDMH) on the State's 2012 Integrated Report as impaired by nutrients (nitrogen & phosphorus) (1996 & 2012), and fecal coliform (1996). MDE has indentified the watershed of the West River (Integrated Report Assessment Unit ID: MD-02131004) on the State’s 2012 Integrated Report as impaired by total suspended solids (2012) and sulfates (2012). 

The fecal coliform TMDLs for the restricted areas in the West River watershed were approved by the EPA in 2006. The Chesapeake Bay nutrient and sediment TMDLs, which was approved by the EPA in December 2010, has addressed the nutrient and sediment impairment listing for the West and Rhode Rivers Mesohaline Chesapeake Bay Segments. The total suspended solid and sulfates impairment listing for the 1st- through 4th-order streams in the West River 8-digit watershed (MDE 2012) will be addressed at a future date. 

The document, available below, establishes a total PCB (tPCB) TMDL for the tidal waters of the West River and the Rhode River, for which a data solicitation was conducted, and all readily available data from the past 5 years have been considered.
