||Section 303(d) of the federal Clean Water Act (CWA) and the U.S. Environmental Protection Agencys (EPA) implementing regulations direct each state to identify and list waters, known as water quality limited segments (WQLSs), in which current required controls of a specified substance are inadequate to achieve water quality standards. For each WQLS, listed in the Integrated Report of Surface Water Quality in Maryland (Integrated Report), the State is to either establish a Total Maximum Daily Load (TMDL) of the specified substance that the waterbody can receive without violating water quality standards, or demonstrate that water quality standards are being met (CFR 2007). The Maryland Department of the Environment (MDE) has identified the non-tidal waters of Cabin John Creek, a Use I-P waterbody (Code of Maryland Regulations (COMAR) 26.08.02.08O), in the States 303(d) List as impaired by nutrients (1996), sediments (1996), fecal bacteria (2002) and impacts to biological communities (2006). All impairments are listed for non-tidal streams. The 1996 nutrients listing were refined in the 2008 Integrated Report of Surface Water Quality in Maryland (Integrated Report) and phosphorus was identified as the specific impairing substance. Consequently, for the purpose of this report the terms nutrients and phosphorus will be used interchangeably. . The 2008 Integrated Report Assessment Unit ID for this listing is: MD-02140207. A TMDL for fecal bacteria was completed in 2006. The listings for suspended sediments and impacts to biological communities will be addressed separately at a future date.
