||This document, upon approval by the U.S. Environmental Protection Agency (EPA), establishes a Total Maximum Daily Load (TMDL) for bacteria in the Duck Neck public beach, Upper Chester River watershed (MD basin number 02130510). Section 303(d) of the federal Clean Water Act (CWA) and the EPA's 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, states are required to either establish a TMDL of the specified substance that the waterbody can receive without violating water quality standards or demonstrate that water quality standards are being met. Duck Neck Beach, a public beach, is located near the border between Kent and Queen Anne's Counties on the southern bank of the Maryland 8-digit basin Upper Chester River (basin number 02130510). Duck Neck Beach is designated as a Use I water: Water Contact Recreation and Protection of Nontidal Warmwater Aquatic Life (COMAR 26.08.02.02). The tidal portion of the basin was first identified in 1996 as impaired for fecal coliform (bacteria). In the 2008 Integrated Report of Surface Water Quality (Integrated Report), the bacteria impairment (enterococci) was clarified and identifies only Duck Neck Beach (assessment unit ID: MD-CHSTF-Duck-Neck-Beach). The designated uses in Upper Chester River were listed as impaired by sediments (1996), nutrients (1996), bacteria in tidal portions of the basin (1996, 2008), impacts to biological communities (2006), and methylmercury in fish tissue in one of the basins impoundments (Millington Wildlife Management Ponds) in 2004. A nutrient TMDL was completed in 2006 for this basin. This document, upon EPA approval, establishes a TMDL of enterococci bacteria for the waters of Duck Neck Beach that will allow for the attainment of its designated use. The listings for sediments, impacts to biological communities and methylmercury in fish tissue within the Upper Chester River Basin will be addressed at a future date.
