Total Maximum Daily Loads of Fecal Coliform for the Restricted Shellfish Harvesting Areas in Tracy and Rockhold Creeks of the Other West Chesapeake Bay Drainages Basin in Anne Arundel County, Maryland.

摘要

Section 303(d) of the federal Clean Water Act (CWA) and the U.S. Environmental Protection Agency's (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, 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. Other West Chesapeake Bay Drainages Basin (basin number 02-13-10-05) was first identified on the 1996 303(d) List submitted to U.S. Environmental Protection Agency (EPA) by the Maryland Department of the Environment (MDE) as impaired by nutrients and sediments in the tidal portion, with listings of fecal coliform impairments added in 1998, and evidence of biological impacts in the non-tidal areas added in 2002. On the 2004 303(d) List, the fecal coliform impairment was clarified with the identification of specific restricted shellfish harvesting area within the basin. This document addresses the fecal coliform impairment listings area identified: Tracy and Rockhold Creeks. The nutrient, sediment, and biological impairments will be addressed at a future date.
