Final TMDLs Approved by EPA: Patuxent River Lower

Battle Creek and Buzzard Island Creek are located on the eastern shoreline of the Lower Patuxent River.  Hog Neck Creek is located along the western shoreline.  The Patuxent River, which drains directly to the Chesapeake Bay, is located on Maryland’s western shore.  Shellfish harvesting waters in the Patuxent River extend from Ferry Landing, which is south of Jug Bay, to the mouth of the river where it discharges into the Chesapeake Bay.

The Maryland Department of the Environment (MDE) has identified the waters of Patuxent River Mesohaline Chesapeake Bay Segment (Integrated Report Assessment Unit ID: MD-PAXMH) on the State's 2016 Integrated Report as impaired by polychlorinated biphenyls (PCBs) in fish tissue (2008) and fecal coliform in the restricted shellfish harvesting areas in Battle Creek (MD-PAXMH-Battle_Creek-2) in 2010 and MD-PAXMH-Battle_Creek-3 in 2014), Buzzard Island Creek (MD-PAXMH-Buzzard_Island_Creek in 2012)  and Hog Neck Creek (MD-PAXMH-Hog Neck_Creek in 2014).  The TMDLs available below addresses the fecal coliform listings for the restricted shellfish harvesting areas in Battle Creek, Buzzard Island Creek and Hog Neck Creek, for which a data solicitation was conducted, and all readily available data have been considered.  The water quality criteria for shellfish harvesting areas is more stringent than the criteria for water contact recreation.  Therefore, the endpoint for the TMDL is also protective of the water contact recreation use.  Note that this report does not address the downstream portion of Battle Creek, MD-PAXMH-Battle_Creek, which is not listed as impaired on the 2016 Integrated Report.  The document uses the name “Battle Creek” to describe the impaired sections MD-PAXMH-Battle_Creek-2 and PAXMH-Battle_Creek-3, which constitute a majority of the Creek.
